Official ExtremeHW DDR5 Memory Overclocking Thread - Share Your Successes and Failures Here!

[Mr. Fox]

I looked around to see if we already had one and did not find a thread for this, so I decided to start one.

 

With DDR5 being the direction things are heading, it's time to shift our attention away from DDR4 to the nex big deal.

 

This has been quite a weird journey for me. Everything I knew about overclocking Samsung B-die turns out to be mostly worthless now. The new bully on the block is S.K. Hynix.

 

I am by no means an authority on the subject, but I will be glad to share what little I have learned with those just getting started, and eagerly learn from those that have learned more than I have.

 

What I meant by weird journey is I have had three DDR5 kits that have had their SPD corrupted and needed to be replaced. All three kits got screwed up on a Unify-X motherboard and I have seen reports of the same thing happening to ASUS Z690 owners. The kits in question were two TeamGroup Delta RGB 6200 kits like the one reviewed by Brother @Avacado and a Corsair Vengeance (non-RGB) 6400 kits between the two. I am on my third TeamGroup Delta RGB 6200 kit now, crossing my fingers and hoping it doesn't happen again.

 

Fearing I may encounter the same circumstances again, I replaced the Unify-X with an EVGA Z690 Dark K|NGP|N motherboard and plan to sell the Unify-X. We shall see how it goes and I will report on the experience here.

[Mr. Fox]

I saw @Splave selling generic Hynix sticks on HWBOT Marketplace for $450 for 2*16GB binned samples. A little too rich for my blood at that price (especially if it gets the SPD corrupted as mentioned above) I found similar modules brand new on eBay and snagged a pair for $80 each. I received them today. Here is what I discovered in my first 30 minutes playing with them.

 

As luck would have it, these naked generic DDR5-4800 SK Hynix modules with no XMP that I purchased brand new on eBay for $80 each overclock better than my TeamGroup RGB sticks, LOL. And, totally naked with nothing but a fan blowing on them they run a good 15-20°C  cooler than memory with stock trash heat sinks beautification covers on them. What a wonderful find at an affordable price. Using exactly the same manual settings they perform better.

 

A few moments later... BOOM - there it is...

 

These are actually running as cool as the Delta sticks were when running on water. It seems like the stock heat sinks we are getting on the overpriced brand-name memory are actually trapping heat rather than shedding it.

 

Conclusion: If you are looking for performance rather than aesthetics, then don't waste your hard-earned money on branded sticks with worthless beautification covers inappropriately labeled as "heat sinks" LOL.

 

Next Steps: Back to the water cooling so I can see how far these sticks can go. $80 each, brand new... what's not to love? And, no need to fart around with buggy garbage RGB software messes.

Great topic idea. Looking forward to seeing people's findings. I will add mine in about a year or so haha.

[Avacado]

Great topic Mr. Fox! I have learned quite a bit from DDR5 as I have been benching with them consistently for many months now. As you stated, SK-Hynix IC's are king right now. There M-dies are killer and their new A-Dies are supposed to be monsters, though I have not read too much on them. As for daily OC with the dark, I am convinced that 7000MHz 1T is possible between 1.6-1.65v with active cooling over top. As for benching, EVGA ELEET is your friend. I have managed some seriously sick timings with the 1T command rate using software based tuning post windows entry. THIS PyPrime HWbot run is from the currently running team competition. We actually need a third sub for that category.

Below are images of the modules and IC close-ups of the memory in my possession for anyone that wants to search for these online for a cheap price as I found them. As you can see from the Thaiphoon Burner data, the generic modules I bought on eBay look to be the same IC as what is on the far more expensive TeamGroup Delta RGB modules, and probably other brands like G.SKILL and Corsair.

 

The generic modules I purchased are Hynix part number HMCG78MEBUA081N. These are M-die IC # H5CG48MEBDX014 DDR5-4800. The Hynix DDR5-5600 A-die module part number is  HMCG78AGBUA081N. I have asked @Splave for a photo of the actual memory IC # and if he is kind enough to share that I will put that information here. Having the IC # can be helpful when purchasing memory modules online when the IC is visible in the photos, because the memory module part number is vendor-specific.

Looks like the seller I bought from now has two more sticks of SK Hynix M-die for sale 

 

Here is more info on A-die. Generic SK Hynix HMCG78AGBUA081N module part number. The memory IC part number for A-die is H5CG48AGBDX018. The JEDEC clock speed for A-die is 5600 versus 4800 for M-die and it seems like the increase in overclock headroom is similar. A-die is not in full production yet and modules using the IC are difficult to find and very expensive.

Really interesting @Mr. Fox!
A French friend is also working on an A-die kit, if he's willing to share some results I'll let you know

Awesome. I look forward to hearing about it.

A-die seems kind of scarce right now and in the rare circumstance I find it, the price is simply too high to justify considering the purchase. I hope the supply of it becomes abundant and the price improves.

[Bastiaan_NL]

I totally agree, I'd love to have a kit but I don't want to waste a lot of money on it before knowing what I can do with it.
With all the hardware coming out soon I need to watch my wallet a bit, don't want to spend it on something that turns out to be useless in combination with next gen AMD for example..

...I put Igor's A-die summary / link  > here last Monday. The oc room he's getting is very promising !

As I was playing around with my Hynix kit on the Z690 Dark board I noticed your post, and I had to try this myself.
Results have been pretty good on the Dark so far, I can squeeze more out of the hardware than on the Hero board. 

First my current best on SPI32m:

 

Now this is on 2 cores, tuned for SPI32m. So not really comparable to your sub, but kinda cool anyways.

Just wanted to say this is a great resource. Well done !

[Mr. Fox]

Well, there is a firmware update out for the Z690 Dark Kingpin mobo, and I have to say it's looking pretty sweet. Has some nice extreme memory OC profiles from Vince (Kingpin) and Luumi. I have generic green M-die and I never dreamed it could run 7800. It couldn't with the previous firmware versions.

 

This is not optimized or stable. Right after I flashed it I grabbed at 7800 profile from Vince in the menu, saved the settings and *BOOM* it ran. Going to be tuning it up so it is stable.

 

Not too shabby for sticks I paid $80 each for, not even part of a kit.

 

[Mr. Fox]

I spoke too soon. Not ready for prime time, but it will be great when they correct a few mistakes.

@evga_james - memory overclocking is much better, but I see a couple of problems. I am running a 13900K CPU.

1. Ring/Cache will not go above 45x. I have it set in the BIOS for 47x. In Windows is shows 45x and it does in ELEET. If I try to manually set it to 47x in ELEET, it goes back to 45.
2. All core clocks do not hold in Cinebench. Cores randomly drop to 800MHz across the p-core and Cinebench scores are 10,000 points lower.

Good first stab at it, but those things need to be fixed before it is a usable firmware.

Thanks for sharing!
I think I checked for an update two days ago and it wasn't there, but glad you tested it so I'll wait
Hopefully by the time I've got a nice kit of A-die we'll have a new bios version.

Also, I had to play around with the 12300 and I couldn't get it to work on the 2.03 sadly. I still have the 1.14 bios saved and it did work on that one. I don't like the fact that BCLK overclocking doesn't work on the newer versions where the memory overclocking should be better, but despite the older bios version I was working with 7020mhz CL28-39-39-28 2T with a chip that doesn't allow a change of SA voltage. I think the CPU could clock higher if I could get it over 130bclk. Maybe one day with some ICE on the core and a bump in voltages all around, but I'm sort of careful with this AVX 12300.

I am finding v2.05 to be pretty decent now. My generic green Hynix A-die modules from China should be here late this week. My M-die modules definitely work better, so I am eager to see how those modules run. The memory I used in making this video are the Sabrent modules that I did the ExtremeHW review on. They are bench stable at 7200, which is pretty impressive for M-die.

My generic naked green A-die sticks arrived today from AliExpress. Seem to be working well, so I will put the jackets and water block from the M-die on them this weekend.

OK, I think I got this dialed in now for my 24/7 overclock. It's so easy to run these generic green A-die sticks at 8000 MT/s. It's ludicrous in light of how many retail kits I RMA'd with RGB rainbow vomit and sloppy loose gamerkidz XMP profiles that cost double, were pure garbage and would barely even boot at speeds like this. Consumers are getting screwed real hard.

That looks fantastic Mr.Fox!  I wish my Unify X could do that tREFI and speed otherwise i think id be right there with you.  Most I can get my board trainable with is 7730, and unless I go back to 67-6800 speed range, my board just wont boot with high tREFI....  Congrats on your tuning sir!
