Ok my friends, for context:

i have a kit of TeamGroup Xtreem 8200CL38 1.40v 2 x 24Gb MDie's, that i'm really fighting with since it needs a lot of VDD.

Doing a direct test of these vs XPG Lancer Rog 6600CL32 A-Die 2x16, at 6400CL28, the XPG needs 1.5VDD or less and the Xtreems need 1.62v and not one volt lower.
Also with this, my VSOC is 0.01v lower on adie, from 1.29 to 1.28v.

So with all this i decided getting a 8000 kit A-Die and this GSkill kit pops up every time.

Any experiences with it? In terms of OC, what should i expect, any examples?
 
That’s a very niche kit and there are a lot of factors here, especially IMC quality of the CPU and the quality of your motherboard.

I’d be very very very surprised if someone here had the same RAM and managed to run the same timings and voltages given how variable the quality of CPUs and motherboards are.

Buildzoid has one CPU that can run very high RAM speeds and that was a sample given to him by AMD and not a retail chip so yeah.

You also haven’t specified your config so are you running Intel or AMD and have you tried other processors and motherboards to see if the RAM is a good bin or not.

You can’t really say “is this memory good” because it really depends on what you’re trying to do - if all you want is bragging rights for the highest RAM speed then that’s different to having benchmark or gaming XOC attempts.
 
I just finished my build new build: 9800X3D with Asus X870E Strix E & Corsair 48GB (2x24GB) DDR5 DRAM 8000MT/s 38-48-48-98
Booted 100% stable on first try at default timings and default voltage (1.4)

I left a review of the 32GB kit on overclockers shop website, I think its the only one TBH, shows everything there, running with a 7950X3D which doesnt have a bad IMC but ive had better with different chips, much better, however I have also got the X670E Gene, so depending on your board and CPU, theres no guarantee you'll be able to hit what I got: https://www.overclockers.co.uk/trid...8-8000mhz-dual-channel-kit-mem-gsk-01363.html

Quick benchmark results.........this is also why im not interested in 9000 series at the moment, RAM latency is rubbish on 9000 as you can see on pvp-forlife link above, hopefully will get fixed with bios updates.

Could you share your sub-timings?
I am running my kit stock atm, once I tweak it, it should be superior to any 6xxx kit out there.

You can see all my timings here on the zen timings screenshot but they won't work on your kit, you'll have to tweak them, the 48gb kit is Hynix M Die, my 32gb Kit is Hynix A Die which does tighter timings.

Regardless of tweaking though, ram latency will still be 10ns slower on Ryzen 9000 compared to 7000, I really don't know why as they share the same IOD, but there's plenty of guys I know holding off from 9000 because of this hoping it will get fixed.

Awesome thanks for sharing - valuable info. There seems to be an intrinsic latency issue, no matter the tweaking, however the starting point is solid so hopefully with bios/microcode updates we will see improvements.
I am still well in the return window, so if the 8000kit is limited I can always return it and swap it for a 6xxxkit
