12 hours stable overnight.

Will test some more tonight, try and get a 24hour memtest done. Though happy for now unless anyone can spot anything obvious.

Try and run with GDM (Gear Down Mode) disabled. I believe if GDM is enabled you're not running a true 1T command rate. You might find what you thought was stable is then not.

Well I've managed 3600mhz 14-14-14-28-2T so far, tRFC at 252 with some tweaks to secondary and tertiary timings I'm just below 50ns on latency :)

It's actually made a considerable difference to my minimum FPS in MW2.

EDIT: One thing I can't acheive is the command rate at 1T. It won't even boot with any of the 1N options selected.
I'd personally run CL16 @1T instead of CL14 @2T. I think I read that the difference between 1T and 2T is about a jump of 2 in CAS terms. I know this is old (DDR3 graph) but here - https://www.anandtech.com/show/2381/8 - shows that DDR-1860 CL8 @1T is quicker than tighter CL7 @2T in the memory read benchmark (bottom graph).

Just went up from 2x8 to 4x8gb sticks of the 8pack 3200/14, spent an evening tuning with a night of memtest and pretty pleased with the result considering its on a 4 layer B450 tomahawk.

Spent the afternoon adjust mine today, have been able to eeek out a few more seconds and lower the voltage slightly too so over happy.

Managed to get to 205, memtesting overnight now and if all is good will call it a day.

My 2x8 gb sticks were definitely easier than my 2x16gb sticks. With the latter I can't get 1900mhz fbclock but that was no issue with previous sticks.

I had to use 1.47v to turn off GDM and tighten timings a bit more.
I am sure I had to also adjust another setting to turn off GDM, but cannot remember off the top of my head.
Great ram for the price.

Going for the following build: 5800x3d w/ rtx 4070, MSI Mag B550 mobo; stuck on RAM selection.

Considering getting the Team Group 8Pack Edition 32GB (2x16GB) DDR4 PC4-28800C16 - cannot quite determine if this ram variant is compatible with MSI Mag B550 Tomahawk, the Team Group 8Pack Edition 32Gb (2x16GB) not showing on the Team Group product compatability inquiry page - https://www.teamgroupinc.com/en/support/compatibility.php

Would be grateful if someone could confirm compatibility.

I'll work fine but that said if you're building new then you should be looking at a DDR5 build.

Got this kit this weekend and this is what I have gotten so far, have not fully stability tested it yet but passed a quick mem test. Any suggestions to improve?

I've just moved from the 16gb kit that would happily sit at 3800 cass 14 at 1.40v to the 32gb kit.

Unfortunately the new kit won't even post at 3800 cas 16 and I've tried voltage upto 1.45.

Also tried 3600 14/14/34 but that doesnt pass memtest and blue screened the pc so at the moment I have it running at xmp.
I have this 32GB kit @ 1.4v 3800MT/s cl16. I have ProcODT 53.3ohms which is what made the difference for me. I went through this guide before:
and ProcODT is the starting point and got rid of my errors running:
https://memtest.org/ Memtest86+ v6.10
I have an MSI mag B550 tomahawk and even with the "try it now" 3800MT/s setting (cl18) it worked.
Using DRAM-Calculator-for-Ryzen-1.7.3 download from techpowerup
and TM5 by 1usmus for further memory stability testing.

I just upgraded my bios to the latest for my board and carried over my timings by taking a picture of the bios memory timings.


tRDWR is 11 as 8 would not boot requiring a cmos reset (8 was from DRAM-Calculator-for-Ryzen-1.7.3)

FYI 2nd pic was done by someone else here:
