I7 4980hq overclockers: Intel Core i7 4980HQ @ HWBOT

Overclocking example:

— Turbo boost case (and only in this case) the operating frequency of the processor is set by turbo boost — the turbo boost multiplier for one core is set to +1 to the maximum, for 2, 3 and 4 cores — the maximum multiplier. So for 4980hq, turbo boost overclocking has the following form — a multiplier of 45 is set for 4 cores, a multiplier of 44 is set for 2, 3 and 4 cores. manually.

— Overclocking with bug and throttlestop — available on any motherboard. Details:

In the case of CW, you do not need to remove microcodes from Bios, because. they are not there anyway. In the rest — I did not study the details, but you can find a discussion in the Haswell topic on the forum. Maybe I’ll add to this section later.

— Overclocking strap 125MHz — available on Z87 and Z97 chipsets. Allows you to reach frequencies higher than those available when overclocking simply by a multiplier. Straps are unlocked on the entire line of CW processors, however, no one will guarantee that overclocking will work in the case of your bundle. It depends both on the implementation of the motherboard and its Bios, and on the implementation of the processor (or its adapter). May be available on the entire line of CrystalWell processors, however, it is believed that selected crystals go to the top model 4980HQ, which is more likely to take higher frequencies.

Strap will not work in 166MHz, because it is tied to the cache frequency of level 4. The L4 cache has a multiplier of 16, at 100 straps it has a frequency of 1.6GHz, at 125 straps it has a frequency of 2GHz. 2656MHz, which he would have received at 166 straps, is impossible for him. There is no multiplier adjustment for L4 cache in this case.

Before overclocking with straps, you need to test the capabilities of your processor — what frequencies are stable and at what voltage, whatever it is, what to dance from.

When overclocking with a strap, make sure that all other multipliers are set correctly. For the first run with a strap, I recommend setting: bus 125 / strap 1. 25, main multiplier 28, Uncore / Cache multiplier — 28, memory frequency — 1066 (when using the strap, it starts as 1333), turbo boost is OFF, you can set fixed voltages for the core and cache . In case of a successful launch, increase the multipliers with voltages in turn.

Overclocking example:

General:

with intermediate checks! On average, CW processors take frequencies from 4.2 to 4.5GHz! Cash takes 3.8-4 (not uncommon with a voltage increase) to 4.2-4.4 on the most successful specimens! Pay close attention to cache overclocking! As well as overclocking the processor cores, unstable cache overclocking instantly leads to «Whea uncorractable error» bluescreens!

— Some motherboards do not display (display fundamentally incorrectly) the core voltage and SA data of processors in Bios and in CPU-Z. This is the norm. Also, you will not be able to measure it on the measurments points of the motherboard. Whether the specified voltage has been set or not — you can see in HWInfo by running the program with the sensors-only checkbox, the voltage is displayed in the Vcore line, but if there is rubbish — the only option is to see what’s in the VID lines.

-Cache frequency (Uncore ratio) must be set manually for any overclocking, I would recommend setting it to 36 if you do not plan to overclock the memory. It is worth increasing this frequency to overclock the memory, so the instances that I had in my hands kept my RAM at a frequency of 2200 with a Cache multiplier of 36-38, but in order for the memory to work at a frequency of 2400, I had to set the Cache multiplier at 40. The voltage for this element and for its overclocking can also be set manually with an override — 1.150-1.2v — safe, and, probably, the maximum voltage.

— The voltages of IO Analog and IO Digital, as in the case of Haswell, can be offset by +0.1 for stable memory overclocking.

-VRIN voltage is an interesting point. When overclocking 4790k, I lowered the input voltage to 1.73v, and this action helped to decently reset the processor temperature by shifting part of the work of the internal regulator to the external VRM. In the case of the Chinese adaptation of crystalwell, such methods led me to blackscreens in the load. Apparently, the Chinese adapter does not use the entire available array of power contacts, which causes a drop in the input voltage. According to my observations, for voltages lower than 1.3v Vcore, the standard 1.8v VRIN is quite enough for itself, but for greater reliability, you can throw up to 1.85-1.9. At 1.35v my stone already needed a minimum voltage of 1.85v, at 1.39v Vcore it needed to set 1.9V VRIN. With a constant margin, I set the voltage to 2v VRIN. Feel free to upgrade.

— Vcore voltage — my opinion is , which is the maximum safe voltage, as in the case of Haswell — 1.4v. It is desirable to set it with an override, however, in the case of easy overclocking, you can also make an offset of +0.05 or +0.1.

— I check the stability of overclocking by 3-5 runs of Linx 0.6.5 AVX for 6GB. I check the stability of memory overclocking and cache using the TestMemory program (TestMem5). It is worth determining the most stable memory and cache frequencies BEFORE overclocking the cores — because. with an increase in their bandwidth, the load on the CPU will also increase.

— It is also desirable to manually set the PCI-E line generation to 3.0. Not exactly related to overclocking, but this recommendation will be here, with all the other Bios settings.

By the way, by itself, overclocking the L4 cache from 1.6GHz to 2GHz, using the 125 strap, according to my observations, does not really give anything: a much more successful memory controller that does not cut throughput at frequencies above 2200, and could well fit into suitable high-frequency modules, for example 2600:

However, unfortunately, this makes no sense due to the low dependence of performance on the memory frequency due to the presence of the L4 cache.

BIOS MODIFICATION:

Anyone can install CrystalWell native microcodes in the BIOS of their motherboards, in some cases it can help solve problems that have arisen, for example, with overclocking. So, for example, I myself encountered the following points — without native crystalwell microcodes, MSI Z9 motherboard7 GAMING5 refused to overclock the memory, GIGABYTE Z87X-UD4H behaved even more inadequately than with them.

WARNING! You can get a brick by flashing a modified BIOS to your motherboard, so please take the time to back up the contents of your motherboard’s Bios chip before modifying. In the absence of a programmer or crooked hands, you can do it quite cheaply at the nearest service center.

Ready-made kitchen with microcode 40661 v17 for MSI and GIGABYTE (tested on MSI and GIGABYTE, bios obtained at the output of this kitchen did not start in the Asrock motherboard) based on the latest version of UBU.

Instruction:

1) put the firmware file in the folder with UBU
2) run via cmd [ubu firmware_file]
3) select «CPU Microcode» in the UBU main menu
4) select C — create FFS with MicroCodes
5 ) confirm — U
6) in the plate that appears, make sure that the list of microcodes contains 306C2, 306C3, 40661
7) press 0 — exit to main menu
8) select Exit

Ready-made kitchen with four microcodes I have (F, 10, 12, 17) for Asus and Asrock motherboards (tested on one Asrock motherboard, in theory it should work with absolutely all brands, but it needs to be checked), based on the old version of UBU .

Instructions:

1) put the firmware file in the UBU folder
2) run via cmd [ubu firmware_file]
3) in the UBU main menu select «Update intel CPU Microcode»
4) select 1. Update CPU Microcode Haswel and/or Broadwell
5) in the case of a motherboard on an 8x chipset — replace the Haswell microcode with the CW microcode, I use 17. (In this case, most likely, the motherboard will not start with Haswell after flashing the modified BIOS), in the case of a motherboard on a 9x chipset — choose Haswell microcode for Haswell, and then change the Broadwell microcode to CW microcode.
6) Press any key, you get to the main menu, select 0 — Exit.
7) Choose 1 — Rename to mod_xxxxxxxxxx
8) you can make sure that the output file is correct by running it through MCE

FINALLY:

A fairly common question is whether the Chinese gluing will fall apart over time? Answer: I don’t know. No one knows. There are usually no problems with large BGA soldering without mechanical impacts, and there are factory models of processors with a similar layout on the market — 7980xe for example.

As for mechanical effects — there are already processors with problems after clamping in the socket, such processors work without problems where they were originally located, but when you try to install in another motherboard, one of the channels stops working due to differences in clamping and socket shapes memory:

At the same time, as a result of such deformation, nickels are pulled out of the adapter textolite, repair by heating or reballing is impossible:
