Any difference between Patriot Viper Steel 4000 and 4400 besides XMP profiles
JavaScript is disabled. For a better experience, please enable JavaScript in your browser before proceeding.
Has the title says is there any other difference between :
Patriot Viper Steel Series DDR4 16GB (2 x 8GB) 4400MHz Performance Memory Kit (PVS416G440C9K)
Patriot Memory Viper Steel DDR4 16GB (2 x 8GB) 4000MHz Performance Memory Kit — PVS416G400C9K
I already have a 8GBx2 4400 Kit considering getting another for DR rank setup.
So is there any real / physical difference between these two kits?
From what I can see its just the XMP profiles that are different or is the 4400 a better bin?

It looks like they are both bdie according to bdie finder, which is surprising since that first kit has pretty terrible timings for 4400 and the second one isn’t great either.
What cpu/motherboard combo do you have? Is the first link the kit you already have?

Yes those are both B-Die Kits. Its the main reason I bought them in the first place. I do have the 4400 Kit listed above 8GBX2.
The Patriot Viper Steel 4400 is actually infamous has being a «cheap» B-Die Kit and there are numerous overclocker’s on this site using this exact kit.
I’m surprised you not aware of just how popular this kit is.

Eh, this one is the one I’m familiar with. I was using it for a bit:
But to answer your question, I would just buy the same kit you already have.

I guess the info at the Amazon link for the 4400 is wrong. It says 19-21-21-41, 1.35v and both 4400 and 4000.
The only Patriot 4400 I know is the PVS416G440C9K at 19-19-19-39 and 1.45v.
If you have one already, I’d say get the same one.
It’s the higher bin of the 2.
One more thing. You will have 2 ranks (dual rank), not 4, because we count ranks within each memory channel.

You are correct the listing for the timings is wrong on Amazon. It is 4400 CL 19-19-19-39 @ 1.45V.
Yes meant 4 X single ranks lol which is Dual rank not quad rank.
I’m also leaning towards paying the extra and just getting another 4400 8X2 kit than buying the 4000 which is cheaper..

Patriot Viper Steel 4000 19-19-19, 4400 19-19-19, and 4000 16-16-16 are all «b-die» sticks
They also behave fairly differently;
—-
UPDATE: if your sticks, when booting up «default settings» — default to DDR4-2666 instead of DDR4-2133, then they’re the new revision on the same (well-behaved, good) PCB as the Viper 4000 16-16-16 sticks, just a worse bin.
The 4000 19-19-19 ones have a lower maximum frequency than the other two, and potentially the weakest secondary (RRD/WTR/tFAW) throughput performance.
They seem to like RTP 7 / tWR 14 or RTP 8 / tWR 14, though some people also run RTP 7 / tWR 10
Unfortunately then I don’t have hands-on experience with them, so I can’t tell many funny details, but they are by far the «weakest» of the three.
preferred RTT’s, something like Nom /6 (40), Wr /3 (80), Park /6 (40) (the divisor is for «»RZQ»», which is 240 ohms)
they have some wiggle-room in what RTTs they can run-run with (not all boards will do Park/6), but those seem to be their «best» performing ones
===
—-
The 4400 19-19-19 ones are closer to the 4000 16-16-16, as they prefer to run at insanely low procODTs and raised DRAM Input Voltage (CPU 1P8 / CPU 1.8v / CPU Standby 1.8v[?aSUS?])
They differ from the 4000 16-16-16 and 19-19-19 ones by having strange odd delay requirements,
(MSI LGA1700)
(AddrCmdSetup 56, AM4)
Both the 4400 19-19-19 sticks and the 4000 16-16-16 do very good secondaries at high frequencies (>= 4200 MT/s), the 4400’s prefer running either RTP 7 / tWR 14 or RTP 6 / tWR 12
on Intel they have high RDWR requirements (17 at 2100 MCLK, +/- 1 each step of 100 [200 MT/s]) and require RDWR_dd to be +1 of _sg/dg/dr (e.
g. 17/17/17/18)
preferred RTT’s, pretty much Nom /6 (40), Wr /3 (80), Park /5 (48) or /4 (60)
these sticks are not friendly if you don’t run those exact RTT’s and a very low procODT
UPDATE:
spotted in the wild:
Apparently you can, instead of wrapping the delay around, just not nudge the signal at all with tCKE to get real 1T working
poggers

The 4000 16-16-16 sticks, on the other hand, seem to be the «simplest» to work with of the three.
On AM4 they effortlessly did 3800 14-14-14-28-42, (tRFC 252-188-116), 1T GDM Off, @ 1.50vDIMM / procODT 28.2 with no funny delays, CADBus 40-20-30-20
something like that, didn’t take screenshots (🤡), didn’t experiment too much: [Official] AMD Ryzen DDR4 24/7 Memory Stability Thread
Unlike the previous two sticks, they do prefer RTP 5 / tWR 10 rather than 6/12 or 7/14.
They seem to have a lower CPU 1.8v-increase requirement — currently running procODT 24 [/15] @ 1.88v instead of 1.
91v like the 4400’s (guy with 4000 19-19-19’s runs 1.93v for procODT 30) —
but I’m not sure how consistent this observation is.
preferred RTT’s, still seem to be the Nom /6 (40), Wr /3 (80), Park /6 (40) of the 4000 19-19-19’s — as those were the only ones to even boot 4600 16-16-16
but unlike the 4400 19-19-19’s, they don’t seem to be very temperamental about it — though they might still be cranky about higher procODT impedances, DIDN’T TEST DIDN’T CARE LOL 🤡
and unlike the 4400’s, you require no weird Delays on AM4 nor LGA1700 — the entire «ODT Delay Duration Configuration» section is set to 0, and runs stable unlike the 4400’s.
On Intel, they seem to run a lower RDWR than the 4400’s, as well as require (it does not negotiate) RDWR _(dr?)/dd to be -1 of _sg/_dg
(e.g. RDWR 15/15/14/14)
RDWR still sort of scales +/- 1 each 100 MCLK
===
tl;dr
(zentimings format of rtt Nom/Wr/Park)
4000 19-19-19: rtt 6/3/6ish, procODT 30, highest cpu 1.
8v(?) + rtp/twr of 7/14, 8/14, or 7/10 + flirts with CAD setup timings, unless super specific CADBus 60-20-40-20
«meh» bin (best I’ve seen is 4200 15-15-15-34-49 @ 1.66v)
idk about daisy good vs. bad slot preference
idk about intel RDWR behaviour
4400 19-19-19: rtt 6/3/5 or 6/3/4 or **** YOU, procODT 28.2 or lower, high cpu 1.8v(?) + rtp/twr of 7/14 or 6/12 + delays/CAD setup timings mandatory(*), CADBus 40-20-30-20(ish?)
decent bin, hits 4200 15-15-15-30-45 @ 1.62v +/- silicon lottery
works great in daisy-bad slots in a 4×8
INTEL RDWR: _dd must be +1 of sg/dg/dr
edit: (* potentially CAD 60-20-40-20 works without AddrCmdSetup 56 ?)
4000 16-16-16: rtt 6/3/6ish, procODT 28.2 or lower, lowest cpu 1.8v(?) + rtp/twr of 5/10 + no delays/cad setup timings, CADBus 40-20-30-20
actually pretty good bin (you can get better for 2-3x the price but who cares), my single reference is 4200 15-15-15-30-45 @ ~1.56v
idk about daisy good vs. bad slot preference
INTEL RDWR: _dr/_dd must be -1 of sg/dg
they’re all within 20 euro of eachother, so turns out the newest of them all, 4000 16-16-16, is the one to buy buy

Thanks for taking the time to post all the above. Will definitely save me some time tuning when I get a Zen 3 CPU.
My current CPU doesn’t really do below procODT 53.3 or 48. In fact my 1700X seems to only like 53.3 I can only do 48 below 3466MT/s
I did get some low timings to pass with a quick TM5 but not useful for daily has the performance from 14-14-14 is almost the same.
If I could get 3800 CL14 with a Zen 3 CPU that would be great. Sadly the 4000 16-16-16 kit is not available in my country and the 4400 is the best option. G.Skill is just
ridiculously overpriced here so that’s not even an option.
Weird issue I have with these Patriot B-die sticks on my system is that they will not pass TM5 without errors @ 3600 at any voltage or timings. But my Dual Rank Rev.E 32GB can do so without any problems.
Do you think the problem is with procODT? This is completely stable when tested with TM5 and Anta777 extreme.

procODT (+ CPU 1.
8v) is an extremely important setting, being the difference between «running» a dual-rank kit I had at RRD 6/12 + WTR 6/12 & tFAW 24 and RRD 4/6 + WTR 4/8 & tFAW 16 (huge improvement)
So yes — you’re still getting memed on by Zen1, unfortunately.
DDR4-3600 is around the point where proper procODT + RTT becomes significant, and >3800 is usually where it is critical.
(Which is why I get the impression 6/3/6 is best on the 4000-16-16’s, being able to boot 4600 16-16-16 1T isn’t simple )
The 4400’s are not that much worse than the 4000 16-16-16 kit — which is very new — they are just more annoying to «make work».
Fortunately the «solution» is right there — AddrCmdSetup 56

Hello
Bloax
The past two weeks I compare some settings according to your reviews and postings with my old setup and I end up with this stable setup
I have 4x8GB patriot Viper steel 4400 CL19 memory sticks
If you have some suggestions to improve that OC I’ll be glad to hear.
Thank you in advance !!

Also if you have some suggestions how can go from 3800 to 4000 or to 4200 with max 1.55v I’ll be glad to hear it to.
Thanks again !!

4×8 Goes up to 4200 for me with different RTT Park for different slots (e.g. CHA/D0 60, CHA/D1 48 & CHB/D0 60, CHA/D1 48) — the problem is that my memory controller does not agree with going that high with b-die 4×8.
Maybe with more «memory support» upgrades, and/or Raptor Lake 🤡
The only «improvement» beyond what you’re showing that I’ve found is that with 1.91v AUX and procODT «[15]» (I still think that’s 360/15), the 4400 sticks accept WTR_L 8 instead of 10 again, as well as tCCD_L 7 instead of 8
which is +1-2% in some things, not a lot, but more than nothing

you have the I7 I have the I9 if I am correct
you have the pro and I have the tomahawk but both motherboards have the same memory controller
and you run different RTT park because you have different memories 2 patriot 4000 and two 4400
is worth it to go for a 4.2 ?
because I know with this I need more voltage on memory

Voltage isn’t really a concern unless you can’t plaster an Arctic P14 fan to rest directly on the memory, as the heat-traps are very easily removed.
My only guess is that different park terminations are good because people have had a lot of trouble running mixed 4×8’s on AM4, maybe it’s fine to have the same for non-mixed PCBs.
What is a concern is that the only way I’ve been able to go past 3866 on 4×8, is through the 29×133 memory multiplier plus BCLK — 100 BCLK doesn’t want to do 39×100 or 30×133, (edit: or anything higher.)

to keep normal temperatures on this memorys is not issues for me as you see in the picture existing fan very close to them
couple months before I was also on 3866 and was more easily to train 29×133
now I am on 3800 full stable and I am very happy with my results
looking forward I’m thinking about 4000 or 4200 G1

Taking the Viper Elite series to the elite level

Tom’s Hardware Verdict
Patriot’s Viper Elite II DDR4-4000 C20 would be a great memory kit if only its loose timings didn’t hold it back.
Pros
- +
+ Average performance
- +
+ Aggressive design without RGB
- +
+ Short heat spreader
Why you can trust Tom’s Hardware
Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.
Practically every piece of modern computer hardware has RGB lighting. The memory market, in particular, is filled with flashy memory kits, and it’s to the point that it’s getting ever more difficult to find normal kits. Luckily for the ‘purists,’ Patriot recently launched its Viper Elite II series, the follow-up to the brand’s Viper Elite lineup. The Viper Elite II not only aims at securing a spot on our list of the best RAM, but the series also looks to capture consumers that still value a good old-fashioned design that’s devoid of all the glitz.

The Viper Elite II memory module sports an aluminum heat spreader with a black and red theme.
The heat spreader feels a bit light in the hand, but it should perform its duties without hiccups. The memory modules are 35mm (1.38 inches) tall, so they’re only a tad taller than the standard memory modules that don’t come with a heat spreader.
There’s zero RGB lighting on the Viper Elite II, so it relies on the aggressive design to stand out from the competition. Patriot implanted the Viper logos on both sides of the heat spreader as well as on top of the heat spreader.

The Viper Elite II features a black, eight-layer PCB. Each memory module is 16GB and has a dual-rank design. The memory modules use Hynix integrated circuits (ICs), although Thaiphoon Burner failed to pinpoint the exact model. The ICs read out as H5AN8G8N?FR-VKC.
The Viper Elite II’s default data rate and timings are DDR4-2666 and 19-19-19-43, respectively. With support for XMP 2.0, the Viper Elite offers two different profiles.
The main profile corresponds to DDR4-4000 with 20-26-26-46 timings, while the secondary profile is for DDR4-3600 with identical timings. The former pulls 1.4V, while the latter utilizes 1.35V. For more on timings and frequency considerations, see our PC Memory 101 feature, as well as our How to Shop for RAM story.

The Viper Elite II found itself right in the middle of the pack in our application performance chart.
However, the memory kit ranked third in our gaming performance chart. It stood out in the Sandra 2020 memory bandwidth test, where it almost caught the Trident Z Royal DDR4-4000 C17.

The memory kit’s standing in the application benchmarks didn’t change when we tested it on the AMD platform.
It did move up a position in the gaming performance chart, though. The Viper Elite II put up its strongest show in the Microsoft Office benchmark, notching a 26% margin between it and the slowest memory kit.
Overclocking and Latency Tuning

Memory Review (Image credit: Tom’s Hardware)Patriot Viper Elite II DDR4-4000 C20 (Image credit: Tom’s Hardware)
It was impossible to squeeze extra frequency out of the Viper Elite II memory kit. We tried using insane levels of DRAM voltage and loosening the timings to the middle ’20s, but to no avail. We’re convinced there isn’t even the slightest of headroom for overclocking, but it could just be back luck in the silicon lottery. As always with overclocking, your mileage may vary.

We had better luck tightening the primary timings for the Viper Elite II at DDR4-4000. A small voltage bump to 1.45V sufficed to reduce the timings from 20-26-26-46 to 18-25-25-45. Those are the borderline values, though, since the memory kit wouldn’t go any lower.
The Viper Elite II DDR4-4000 C20 has an appealing design and acceptable price tag, but average performance. Our tests showed that the memory kit’s loose timings didn’t allow it to stand out in any meaningful way. DDR4-4000 at CL20 is pretty hard to swallow, considering it’s at the bottom of the barrel in the DDR4-4000 category.
Patriot’s memory kit currently retails for $195.99. It’s not the worst pricing on the market for a DDR4-4000 memory kit, but it is on the more expensive side, especially considering there shouldn’t be an RGB tax.
There are more compelling options in the Viper Elite II series, but this DDR4-4000 C20 memory kit simply doesn’t offer the best bang for the buck.
