FEATURED Woomack's memory test list

[Woomack]

One more Hynix A-die kit - ADATA XPG Lancer RGB 32GB DDR5-7200 CL34 1.40V, added to the list. It's the same kit as previously reviewed, but in the standard version (before it was Limited Mera Edition).
The next one will be G.Skill 2x24GB 7600MT/s.

 

[Woomack]

G.Skill Trident Z5 RGB 48GB DDR5-7600 CL38 and Acer Predator Hermes RGB 32GB DDR5-6800 CL32 kits were added to the list.
G.Skill review is on the front page - 2x24GB Hynix M-die kit, overclocks well past 8000MT/s.
Predator Hermes RGB is a Hynix A-die kit. It's the lowest CL kit on the market at 6800MT/s. Overclocks above 8000MT/s+ too. This is pretty much expected from 2x16GB Hynix A-die kits

The next in the queue is Corsair Dominator Titanium 48GB DDR5-7200/7400 (officially 7200, but has 7400 XMP profile, too), but as usual, I have delays I can share that it goes up to 8400MT/s.

 

[Woomack]

Two kits have been added to the list:
Dominator Titanium 48GB DDR5-7200 / Hynix-M
KLEVV CRAS V RGB 32GB DDR5-6400 / Hynix-A

 

[Woomack]

Crucial Pro 2x48GB DDR5-5600 has been added to the list.
It's a regular Micron-based kit, but it's the cheapest option at such a high capacity. It still overclocks past DDR5-6000 at tighter timings than in the XMP/EXPO.

The next in the queue are 3 Patriot kits and something from V-Color.

 

[Woomack]

Patriot Viper Xtreme 5 RGB 48GB DDR5-8000 has been added to the list. The review is on the front page.
It's a great overclocking Hynix M-die based kit. If not for the limitations of the test platform, it would probably go up to 9000MT/s. It overclocks about the same as the 8200MT/s kit, which will be reviewed soon.

Patriot Viper Xtreme 5 48GB DDR5-8200 review is on the front page and added to the list - click
As I mentioned, it's pretty much the best overclocking M-die you can find. It went up to 9000MT/s, but I wish my CPU/mobo could make some more, as it limits stability much below that - details in the review.

 

[Woomack]

V-Color Manta XPrism 2x24GB DDR5-8200 CL40-52-52 1.40V memory kit review has been added to the list.
One more Hynix M-die kit that can make 8600MT/s+ ... just good luck with the CPU+motherboard

 

[Woomack]

KLEVV CRAS V RGB 2x16GB DDR5-8000 CL38-48-48 1.45V memory kit review has been added to the list.

One more Hynix A-die 8000 kit. Overclocks pretty good - 8400+, temperatures are reasonable, the price isn't bad, and RGB looks well, too. In short, it's a very good 8000 memory kit. It also supposed to work on AMD motherboards as it has EXPO profile, but I had no chance to test it on AM5. Most new Hynix A/M kits don't have problems with that, and the CRAS V RGB DDR5-6400 kit, reviewed some months ago, was working on AMD without problems.

I may review some SODIMM DDR5 kits soon. With some luck, 3-4 kits, and probably with some overclocking results. I'm waiting for replies from vendors right now, but at least one kit was already shipped.

 

[Woomack]

Crucial 96GB DDR5-5600 SODIMM review has been added to the list.

Even though this memory looks quite standard, you won't find anything faster for laptops at this capacity.
At standard 1.10V, it overclocks up to 6200MT/s CL42. I couldn't change the voltage on my motherboard. It clearly needs memory with a proper PMIC for overvoltage.

In the queue right now is:
Team Xtreem 48GB 8000 CL38
Kingston Fury 96GB 6400 CL32
Kingston Impact 64GB 5600 CL40
Crucial Pro OC two 2x16GB kits 6000 CL36

 

[Woomack]

I don't have much time to review this kit, but I want to leave it here.
Kingston Impact SODIMM 2x16GB DDR5-6000 CL38 @ 6800 CL32-39-39 ~1.40V




Timing options are limited in BIOS. It's benchable at 7000 CL32, but I can't stabilize it. Maybe it's a matter of standard IMC voltage, as it's also missing in BIOS. Either way, it looks pretty good.

 

[Woomack]

Crucial Pro OC 32GB DDR5-6000@7000 CL38 1.40V / Micron D-die.
The review will be soon, but I wanted to share one quick OC result. It posts at up to 7600, but I couldn't stabilize it above 7000. It's still the best overclocking Micron IC so far, but also not even close to Hynix A/M.

 

[Woomack]

Crucial Pro OC 32GB DDR5-6000 CL36-38-38 1.35V EXPO/XMP memory kit review has been added to the list.

There is a promo on Amazon right now, and this kit costs $104.99. Just letting you know if you are searching for a reliable and inexpensive 32GB DDR5 kit.

 

[Woomack]

Kingston FURY Impact 2x32GB DDR5-5600 CL40-40-40 1.10V SODIMM review has been added to the list.

In short, Hynix A-die IC, and if you have a motherboard/laptop that overclocks without issues, then you can push it much higher. My test motherboard, for some reason, didn't like PMIC and no matter what I did, it was forcing 1.10V VDD/VDDQ (even though software was showing more). Still, at 1.10V I could stabilize it at 6000MT/s CL36-38-38, which is a great result for standard voltages.




The next in the queue are 3 regular DIMM kits:
Team Xtreem 48GB 8000 CL38 / Hynix M-die
Kingston FURY Renegade 96GB 6400 CL32 / Hynix M-die
KLEVV BOLT V 32GB DDR5-6800 CL34 / Hynix A-die

Neat that you're able to tweak a SODIMM kit. Any idea which laptops support that?

I have no idea. I picked a Minisforum motherboard for that - AR900i with soldered 13900HX cost me like 14700K in Dec last year. It's about 1/5 of the price that a typical laptop with this CPU costs. It's the only SODIMM motherboard that supports RAM overclocking. I also see that no one reviews SODIMM, so I thought, why not do that?
Minisforum officially says the AR900i motherboard doesn't support overclocking, but somehow it does, up to at least DDR5-7000 (no MC voltage, so I can't even try higher). It also officially supports only DDR5-5600 max and doesn't support XMP, but in reality, it does.
The manufacturer couldn't say anything about RAM compatibility besides it is supposed to work with a regular/JEDEC 2x16GB Kingston kit. Officially, it supports 64GB max, but I tested it with 96GB 5600@6200, and it works fine. With Kingston 6000/XMP kit, it goes up to 6800 stable. Sub-timing options are limited, but the performance is still pretty good. VDD/VDDQ voltages do not always work. It depends on the used PMIC, and even then, it's not guaranteed it will work. So far, voltages work only on Kingston kits with XMP (so there are only 2 kits).
Considering how many SODIMM kits I have already tested, my QVL is much longer than the manufacturer's one

I also have a Minisforum motherboard with a Ryzen 9 7945HX / 16 core/32 thread, but it doesn't support RAM overclocking at all. It works at DDR5-5200 with 5200/5600 kits, and the 6000 XMP kit works only at 4800. It still works at 5200 38-38-38 1.10V with 5600 40-40-40 kit (the one from the last post).
I have the AMD motherboard on my 24/7 PC. It also supports 2xM.2 PCIe 5.0 and has a PCIe x16 5.0 slot. 32 threads with boost up to 5.45GHz and 55W TDP. It's possible to unlock power limits, and then it keeps the max boost for longer and on all cores.

Btw.
Team Xtreem 48GB 8000 review has been added to the list - the review is on the front page if anyone missed it.
One more Hynix M-die kit that can make 8600+. The main difference is the design; there is no RGB, but there are high-end-looking heatsinks.

 

[Woomack]

KLEVV BOLT V 2x16GB DDR5-6800 CL34-40-40 1.35V review has been added to the list.

Hynix A-die IC, overclocks up to at least 8200MT/s. Results were slightly worse than on 8000 kits with A-die, but maybe it's the latest BIOS, as I flashed it multiple times since the last A-die tests.

Kingston FURY Renegade RGB 2x48GB DDR5-6400 CL32 review has been added to the list.

It's the best 96GB kit you can get. As expected, it's Hynix M-die, but dual-rank. I had limited time, but my kit overclocks up to 7600. If I work some more on sub-timings, then maybe it will reach 8000. Maybe I just need a different BIOS as it was acting weird at 7800.
Kingston also has the best RGB backlight - infrared synchronization, so it doesn't require software to put colors on track, and you can't count LEDs looking at the top bar.

Hi there. Thank you very much for your continued work on this.

If I may ask a bit of a subjective question, but with your testing, do you think DDR5 "dual-rank" performance could ever be worth it over very fast "single-rank"? For example, that 7600 2x48gb kit compared against a 8400 c38 2x24gb kit.

Hi there. Thank you very much for your continued work on this.

It's easier to stabilize 2x32GB/2x48GB of Hynix A/M at 7400-7600 than 2x16/2x24GB of Hynix A/M at 8200-8400. This is because, except for only a few motherboards, most won't run at 8200+, and most CPUs won't run at 8200+ either. So with dual-rank, you will faster see RAM limitations, with single-rank IMC/mobo.

In a perfect environment, assuming that you can easily set dual-rank at 7600 and single-rank at 8400, it doesn't really matter as the difference in games will be like +/- 0-1%, and in other software, you can wait that 0.05 seconds. Most software is scaling pretty well up to ~7200 single-rank, where the comparable performance of dual-rank is anywhere between 6400 and 7200, depending on the software used. Above ~7200, the difference is barely visible in everything except for low-resolution games. However, it doesn't matter much if there is 250 or 270 FPS.

It also depends heavily on the CPU used. For 1CCD AMD, it doesn't matter if you use 6000 or 8000 or if RAM is single or dual rank. For Intel, it's better to get faster RAM, but as I mentioned, it's not scaling well past 7000-7200, so it's not worth spending too much unless you need it for a specific usage.

Btw. I have 2x32GB Kingston Fury Renegade 6000 CL32 and 2x48GB 6400 CL32. Both overclock up to 7600, but on some motherboards, more than 7200 is not easy to stabilize.

Hello there. Thanks for entertaining my question. Yes, "dual-rank" will always be more difficult to clock higher, but DDR4 seemed to yield larger performance gains compared to DDR5 when it came to dual vs single rank.

I haven't tried any "dual-rank" DDR5 yet, but I have done some black and white tests of stock 5600 vs 8400 c38 "single-rank" and I've seen up to 20% increase in FPS in best case scenarios. Unfortunately, I haven't tried anything in between like 7200, so I can't confirm whether the scaling falls off a cliff after that point. I would guess that it would be largely application or game specific.

Manta has some 2x48gb 7800 sticks I may want to try for fun.

So, with your best guess, how much do you think "dual-rank" is worth in terms of "single-rank" speed of DDR5? For example, maybe 7600 "dual-rank" could be equivalent to 8000 "single-rank"?
