Intel Core i7 Build: Overclocking the Intel DP55KG and Core i7 860
This is the third post documenting my upgrade to an Intel Core i7 Lynnfield system. In my first post I discussed the components I selected and why. I talked about assembling the system and some of the challenges I encountered in my second post, and in this final post I’ll be discussing my efforts at overclocking the Intel DP55KG motherboard and Core i7 860 processor.
Two Approaches
Intel’s new “Turbo Mode” feature is able to increase the processor multiplier value beyond its default value (21 in the case of the Core i7 860) if the processor is operating within what it considers are safe temperature parameters. For example, in Intel’s Core i7 Bloomfield architecture, processors are allowed to raise the stock multiplier value by 1 or 2 depending on the number of cores being used. Intel’s Lynnfield processors are considerably more aggressive with Turbo Mode, increasing Turbo Mode multipliers within a range of ~2-5. Essentially what this means is that when fewer processor cores are demanded by an application or process, larger multiplier values are used, thus the processor is allowed to run faster than the default multiplier would normally allow. In the case of the Core i7 860, it’s not uncommon, for example, to see it use a multiplier value of 26 in single-threaded applications, yielding a processor speed of 3.46 GHz, well above its stock speed of 2.8 GHz. While this sort of dynamic overclocking is pretty damn impressive, a question arose for me when it came time to overclock my Intel DP55KG and Core i7 860: should I attempt to overclock the system with Turbo Mode enabled, meaning I would have to consider the headroom required when higher multiplier values are used, or should I simply disable it and go with the more traditional overclocking approach? I ended up trying both approaches to see how they compared and to evaluate which would work best for me.
Regardless of which approach you use though, overclocking a Lynnfield system is pretty straight forward. Adjust the host clock frequency until the system achieves a stable CPU speed. From there, the memory multiplier can be adjusted to compensate for the change in host frequency. If desired/needed you can also adjust the CPU voltage, memory voltage, and Uncore voltage to further stabilize the system. That’s pretty much all the adjusting the architecture allows you to do.
- Turbo Mode enabled
My first attempt at overlocking the Intel DP55KG and the Core i7 860 involved raising the host clock frequency but leaving with Turbo Mode enabled. These are the BIOS settings I started with:
Performance
Host Clock Frequency Override: Manual
Performance -> Processor Overrides
CPU Voltage Override Type: Dynamic
CPU Voltage Override: Default (default)
CPU Idle State: High Performance
Intel Turbo Boost Technology: Enabled (default)
Performance -> Memory Configuration
Performance Memory Profiles: Manual – User Defined
Memory Multiplier: 12
Memory Voltage: 1. 65
Uncore Voltage Override: 1.10 (default)
Performance -> Bus Overrides
All settings in this section were left at their default values.
Power
Enhanced Intel SpeedStep Tech: Enabled (default)
CPU C State: Enabled (default)
With this approach, my objective was to try to achieve the best stable overclock I could using Turbo Boost and leaving the voltage settings at thier default values. However, I did alter two voltage settings: the CPU Voltage Override Type, which I set to Dynamic, allowing the CPU to still manage its own power usuage but with higher upper limits; and the Memory Voltage, which I set to 1.65 to match the voltage input specified for my Mushkin DDR3-1600 kits. I left the RAM timings at the default SPD values of 9 9 9 24.
And the result? I was able to achieve a host clock frequency of 154 MHz before the system became unstable (stability in this case is defined as the ability for the system to run without failure using Prime95 (v25. 9) Large FFT for 2-3 hours). This yielded a CPU speed of 4 GHz, assuming a Turbo Boost multiplier of 26 (154 * 26 = 4.00 GHz). I did notice, however, that the multiplier in my case generally liked to stay at 25 a large percentage of the time during idle. I suspect this was the result of the High Performance setting in BIOS that forces the system to use the higher multiplier when the operating system would otherwise be allowed to lower it.
According to CPU-Z (v1.53) The CPU voltage (VID) fluxuates between .8 and .9 at idle and core temperatures according to Speedfan (v4.40) were ~30c at idle. Given the DRAM multiplier setting of 12, the DRAM frequency weighed in at a nice 1848 MHz. Loading all four cores resulted in VID rising to 1.096 volts and core temperatures to ~63c. Using all four cores of course also resulted in the system using the default CPU multiplier value of 21 (154 * 21 = 3.23 GHz).
So, in summary, I was able to achieve ~15% overclock under load using Turbo Boost and leaving the voltage settings at thier default values.
- Turbo mode disabled
After determining the optimal overlocking settings for my Intel DP55KG and the Core i7 860 using default voltages and Turbo Mode enabled, I attempted to overclock the system with Turbo Burst disabled as well as the freedom to use higher voltage settings, if necessary, to make the system stable. These are the BIOS settings I started with:
Performance
Failsafe Watchdog: Enable (default)
Host Clock Frequency Override: Manual
Host Clock Frequency: 133
Performance -> Processor Overrides
CPU Voltage Override Type: Static
CPU Voltage Override: Default (default)
CPU Idle State: High Performance
Intel Turbo Boost Technology: Disabled
Performance -> Memory Configuration
Performance Memory Profiles: Manual – User Defined
Memory Multiplier: 10
Memory Voltage: 1.65
Uncore Voltage Override: 1.10 (default)
Performance -> Bus Overrides
All settings in this section were left at their default values.
Power
Enhanced Intel SpeedStep Tech: Disabled
CPU C State: Disabled
And the result? With Turbo Burst disabled and the latitude to increase VID and other voltage settings if necessary, I was able to achieve a host clock frequency of 170 MHz using a VID of 1.2 before the system became unstable, yielding a CPU speed of 3.5 GHz (170 * 21 = 3.57 GHz). Further increases in VID, memory or Uncore voltage did not allow for a stable system using higher clock speeds. Core temperatures rose to ~35c at idle and loading all four cores caused the core temperatures to rise to ~74c. With a the DRAM multiplier setting of 10 instead of 12, the DRAM frequency fell to 1700 MHz. Here again I left the RAM timings at the default SPD values of 9 9 9 24. I did try to run with the DRAM multiplier set at 12 but there was just no way my 1600 MHz RAM was going to run at 2040 MHz!
So, in summary, I was able to achieve ~28% overclock by shutting down Turbo Boost and raising VID to 1. 2.
Comparison
Afterwards, I threw a few highly unscientific tests at both cases to see how they compared. The first involved transcoding a typical MPEG-2 DVD *iso to the h.264 high-profile format using Handbrake. There was no significant difference in time between the two methods, however both represented a nice improvement over the default settings. Turbo Boost, however, did provide a nice bump in memory bandwidth, due mostly to the ability to run at a higher DRAM multiplier value. The use of Turbo Boost also won out when running 3DMark Vantage, suggesting that the higher multipler values played a role. The game-based tests I ran were essentially useless since the particular games I had on hand to test with (BattleForge, Crysis, and X3 Terran Conflict) more strongly rely on the GPU for performance improvement and not the CPU.
Conclusion
Turbo Mode is something that should be evaluated based on your needs and the specifics of your overclock. Which one did I go with? I decided to run with Turbo Mode enabled and the lower host clock frequency. There were a couple of reasons for this choice. First, I rather like using the default voltage settings; by allowing Intel to manage the power settings, I’m able to run my system moderately faster, and in some cases a hell of a lot faster, but also a lot cooler. Second, I typically run applications that do not utilize all four cores, so a moderate overclock with Turbo Mode gives me better results than a higher-speed overclock without Turbo Mode. However, it’s good to know that as I grow to depend on more cores consistently, I can simply shutdown Turbo Boost and clock the system higher.

Now that my OS’s are the way I want them.
I thought I’d try researching and then attempting to Overclock my Core i7 860.
After reading the 3 STEP GUIDE on Overclockers.com
I gave it ago and then found this on youtube
Found this on YouTube
Now obviously this wouldnt be your 24/7 speed, but could you use this method from youtube and run constant 3.5ghz ?
If i try it I will be using PRIME95 or LINX as the 3 STEP GUIDE mentioned for testing.
UPDATE
Got home from work and tried the Youtube advice from the link above.
So..In BIOS..After loading DEFAULTS then resorting back to AHCI instead of IDE
I then made the following changes
-ADVANCED CPU CORE FEATURES-
INTEL(R) TURBO BOOST TECH. — DISABLED
CPU MULTITHREADING — DISABLED
CPU ENHANCED HALT (C1E) — DISABLED
C3, C6, C7 STATE SUPPORT — DISABLED
CPU THERMAL MONITOR — DISABLED
CPU EIST FUNCTION — DISABLED
-ADVANCED FREQUENCY SETTINGS-
BASE CLOCK (BCLK) CONTROL — ENABLED
BCLK FREQUENCY(MHZ) — 185
SYSTEM MEMORY MULTIPLIER (SPD) — 8. 0
-ADVANCED MEMORY SETTINGS-
PERFORMANCE ENHANCE — STANDARD
DRAM TIMING SELECTABLE (SPD) — QUICK
-ADVANCED VOLTAGE SETTING-
LOAD-LINE CALIBRATION — ENABLED
ALL OTHER VOLTAGES AT AUTO
Saved settings and booted into WINDOWS successfully.
Once opened the following and ran linx with all available RAM for 20 runs.
See results below.

Just ran MEMTEST86+ v4. 00 x 1 PASS
No errors there either
See below

Anyone want to tell me how much of a douch bag I am, go right ahead.
After all I am obviously new to this whole OC thing & can take criticism.
Pay attention to my sig as I am not using stock FAN! Would not have attempted this if that was the case.
Now just a bit scared to turn on HYPER THREADING (MULTITHREADING), EIST, C STATES etc.
If anyone has any suggestions as to what I should do from here let me know.

After speaking to a mate at work who has oc’d his 920, I’m thinkin of turning off EIST (SpeedStep) and MULTITHREADING.
Will reseat heatsink tonight though prior to switching those 2 features off and see if that lowers temps at all.

This is the fourth and, most likely, the final material on the Socket LGA1156 platform. In the past, we checked representatives of the Core i3 and Core i5 series for lice, and now we can please you with a gaming test Intel Core i7-860 .
This is a 45nm member of the Lynnfield family with the Nehalem microarchitecture. He got at his disposal 4 full-fledged cores in 8 threads with a base frequency of 2.8 GHz and dynamic overclocking to 3.46 GHz. Just imagine — from 2009 to 2017, the top mainstream Core i7 series used just such a configuration of cores and threads. And only with the release of Coffee Lake the situation changed for the better.
This chip also includes a 2-channel DDR3-1333 memory controller, and its TDP is 95W.
The test stand has not changed. At the core is the GIGABYTE GA-H55M-UD2H motherboard. It supports the installation of not only mass, but also some server processors of the Xeon line after a firmware update. With DualBIOS technology, it is safer to do this.
The RAM subsystem is represented by a quartet of 4 GB modules DDR3 from Samsung , which nominally ran at 1600 MHz. From the very beginning, the BIOS saw all 16 GB, and Windows only 8. I had to wipe the processor contacts several times so that the OS saw the entire available volume.
Comfortable processor temperature was maintained by 3-section dropsy Cooler Master MasterLiquid ML360P Silver Edition . To do this, it includes a water block with a large copper base, an aluminum radiator with a density of 20 wafers per inch and a trio of 120 mm turntables.
The disk subsystem is represented by a pair of terabyte SSDs PATRIOT P200 . To speed up the work, they use SLC caching technology. After filling up 35% of free space with continuous recording, the speed drops from 460 to 240 MB / s.
We have a processor test, not an assembly, so we took a productive video card Palit GeForce RTX 2080 SUPER GameRock , so as not to run into the video subsystem. For this, the reference frequency formula is enough for her, because all tests will be held in Full HD.
Our processor is old, but powerful and demanding on the quality of power. The RIOTORO ENIGMA 750WG2 unit with 80PLUS Gold certification, fully modular cabling and a 120mm fluid dynamic bearing fan satisfied his requests without any problems.
Case RIOTORO CR1288TG was also taken with a margin. This is a full-fledged Full Tower with an elegant exterior and thoughtful interior. The top panel has four USB ports, a pair of audio jacks and LED backlight control buttons.
BRAIN and Vinga helped with peripherals. The gameplay is recorded by an external system with AVerMedia Live Gamer 4K, that is, without performance loss.
Overclocking didn’t work out very well. In 2009, we managed to overclock the Core i7-860 to almost 4100 MHz. This time I got a not very successful copy of the processor, and the motherboard cannot be called an overclocker’s dream.
The system successfully started with a CPU frequency of 4.2 GHz, but there was no stable operation, and I had to roll back, and then again and again. Even with a significant reduction in overclocking, during the stress test, the frequency began to dip from 3500 to 1400 MHz. Games in this mode constantly freeze. You can raise the voltage, but then throttling appeared and it got even worse.
The system was completely stable only at 3. 4 GHz. To achieve it, we raised the system bus frequency to 155 MHz and simultaneously increased the voltage of Vcore, QPI bus, chipset and memory. By the way, the RAM worked at a frequency of 1860 MHz. In this mode, the system passed all stress tests, and the maximum temperature of the cores did not exceed 70°C.
Then came the turn of two standard synthetic benchmarks. In CPU-Z , the overclocking bonus was 16%. If in nominal value the Core i7-860 lost to the no less legendary FX-8350 in multi-threaded mode, then after overclocking it emerged victorious in both tests.
In CineBench R15 , the increase does not exceed 18%. At face value, the 860 bypasses the Core i3-7100, and after overclocking it approaches the Core i5-7400.
In gaming benchmarks, using three popular APIs as an example, the situation is as follows. World of Tanks EnCore RT with an average preset estimated the increase in performance at a maximum of 19%. Although the nominal results are more than comfortable.
In Shadow of the Tomb Raider , there is a noticeable increase of 17% only in the average speed. The rest of the statistics remain virtually unchanged.
In Wolfenstein: Youngblood overclocking had the most positive effect. The indicators have grown by a maximum of 19%, and this will really make the gameplay more enjoyable.
As a result, the average increase is 14%, which is not bad for this level of overclocking. In online projects, you may not even feel it, but in heavy blockbusters, he is a welcome guest.
In general, the system feels more responsive and faster than the previously tested processors. Therefore, for tests, we selected several heavy topical games and indulged in ray tracing. But let’s start by tradition with simpler online projects.
The system pulls Dota 2 with the maximum quality preset without any visible problems. In the process, only the 0.1% Low indicator drops below 40 fps, but there is still sufficient margin to the heart attack zone at 24 FPS. The average speed is kept around 90 frames / s.
World of Tanks flies on ultras, no problems are observed. On a fast light tank, we get over 90 FPS on average, with good statistics on rare and very rare events. You can play for fun and not be afraid of friezes at the most crucial moment.

Topic: Overclocking i7 860.
Who the thread is the owner of such a process. It just needs to be overclocked to the maximum for CPU-Z validation until this is the only way to get a validation link. Does anyone have any suggestions to improve the rezalta?
Also, if anyone has a thread i7 875 k?
I just want more air.

Re: Overclocking i7 860.
What is the native frequency of the memory? you can pull out one bar, play around with the timings — only the frequency is important to you.

Re: Overclocking i7 860.
1866 memory . Everything rests on the percentage and its voltage + mother at the limit of the base frequency + memory controller at the limit. max per percent I can apply 1.5 well, this is in cases of hopelessness
ideally you need a frequency of 4700-4800, well, at least 4600-4650

Re: Overclocking i7 860.
Link for something that I won’t be able to do anymore or that two cores were disabled there for a larger multiplier. For now, I want to pass validation on 4 cores (find the ceiling). Then I will naturally disable 2 cores on Hwbot, this is not prohibited. I need help who has unraveled such processes, or knows about them. And I, as it were, can use the Internet myself.

For such a process, you need a lot of beer, then a lot of vodka, and 20 tons of liquid nitrogen. Then he will be strong.

Who the thread is the owner of such a process. It just needs to be overclocked to the maximum for CPU-Z validation until this is the only way to get a validation link. Does anyone have any suggestions to improve the rezalta?
Also, if anyone has a thread i7 875 k?I just want more air.
Mother asus maximus gene iii
Memory Corsair Vengeance 1866
I have one so what?
want to buy

New life for an old computer! Processor Intel Core i7 860, 8 «cores» for $100.
Greetings to all!
Recently, my work computer on intel core i3 does not quite cope with the tasks, especially when it comes to encoding / editing video. More performance requires a more powerful processor. Basically, exporting a video lasting 15-20 minutes took from 40 to 1. 5 hours, depending on the number of tracks and applied effects. Since I don’t want to completely change all the insides of the PC, I thought about changing the processor to a more powerful one and suitable for my relatively outdated motherboard. For more information about what happened as a result — see under the cut.
The highest performance processor supported by my ASRock H55DE3 motherboard is the Core i7 860-885k line. There is no point in looking for 885k, since it is not really rare, and the difference is only in a higher frequency, which can be easily compensated for by weak overclocking. This processor is no longer produced and it is very difficult to find it on sale even used. Of course, you could find a used one. i5 750-760 for the same $100, of course there would be an increase, but not the maximum. I already have an i5 760 installed on my second computer, and I have something to compare with. The feature of the old i3 530 processor is that, although it is two-core, it has the Hyper-Threading function, which gives it 2 more virtual (logical) cores. And in benchmarks, it shows results at the level of full-fledged 4-core models. By the way, the i7 860 processor was primarily interested in the support of Hyper-Threading technology. i.e. in task manager and other applications it will have 8 cores !
So I looked through ebay and aliexpress, found several interesting lots from China, but one seller was from Germany, the price with delivery was about $ 120 for a used percent. The seller has a 100% rating and a large number of sales. In general, I made an order.
Delivery by DE mail took almost 2 weeks.
For the first time in my life, I ordered a processor from ebay and there was a slight fear that it might not come working. Surprisingly, when the package arrived, it was undamaged, a neat cardboard box, it contained a protective package, and it contained a processor wrapped with a pimply tape.
It only remained to install this rare beast 🙂
Characteristics of i7 860:
Issue date: Q3’09
Model: i7-860
Cache: 8MB
Tech process: 45 nm
VID voltage range: 0. 6500V-1.4000V
Hyper Threading — Yes.
Number of cores: 4
Number of threads: 8
CPU Base Clock: 2.8 GHz
Maximum clock speed with Turbo Boost technology: 3.46 GHz
Rated power: 95W
Number of transistors in the processor core: 774 million
Supported connectors: LGA1156
Let’s go directly to the processor itself and its installation. I prepared some Noctua NT-h2 thermal paste from old stock in advance, this is a very effective thermal paste from a well-known manufacturer. I also got a Scythe Shuriken cooling system from a friend.
The last 3 years the computer worked in the mode of 15-16h -365 days a year. Accordingly, having removed the old cooler, it is noticeable that the thermal paste has dried up a long time ago.
My old i3 530 has served me faithfully for over five years, and has handled everything except video encoding.
We take a new i7 860.
Set to socket.
On top of the processor in the very center we drip a drop of thermal paste.
As it was:
How it became:
By the way, I use different memory, one pair should work from 1.25V, the second pair from 1.8V, as a result, using the test method, I set the average voltage for both modules — 1.45V
Bios info.
Testing processors in the Aida benchmark, all 3 pcs operate at a frequency of 3.2-3.3Ghz.

Processor i7 860 . CPU Queen 36681 , FPU Julia 10636 , Memory Read 13714Mb\s , Write 11622Mb\s , Latency 50. 8ns .

In total, I got almost a two-fold increase in productivity for an adequate amount. In terms of CPU \ FPU, the speed of reading and writing from RAM has increased, memory latency has decreased, and 8 cores in the task manager also look unusual. =) Bottom line — my goal is achieved. Now a standard 15 minute video is exported in 20-25 minutes depending on effects and tracks. At the same time, the loading of the video card has increased from 30-50 to 50-75% during processing. You can painlessly raise the FSB frequency to 150mhz, although at the moment I have enough of such indicators with my head.
Advice for those who want to increase the overall speed of the computer — install the operating system on an SSD drive, the cheapest 60 Gb is enough. Replacing a hard drive from Windows 7 to an SSD (without reinstalling) — reduced the time to start the computer to the desktop from 1-1.5 minutes on a 1TB hard drive to 15-20 seconds with a dozen programs at startup + complete silence during operation.
