DDR5 Memory overclocking - Samsung Bdie

Jay85 · 18 Jun 2022 at 12:51

Anyone managed much success with overclocking DDR5 yet?

I've managed to settle my cpu overclock over the past 2 days at a point where im happy with both temperature, voltage and speed and now looking at upping the speed on my memory kit. The kit has the sku CMK32GX5M2B5600C36 5600mhz 32gb (2x16gb) kit Samsung Bdie, i think i want to aim for 6000mhz without much tweaking initially so something like just upping the voltage to 1.3v from 1.25v and increasing the speed to 6000mhz and go from there.

Any other suggestions or what you've managed to achieve?

Hi Jay85. Where you able to succesfully OC the CMK32GX5M2B5600C36 5600mhz RAM to 6000mhz and keep the 36,36,36,72 timings? I am curious because I'd like to do the same thing. The 5600mhz kit is $100 less than the 6000mhz kit. The 5600mhz kit runs at 1.2v. The 6000mhz kit runs at 1.35v. Otherwise timings are the same. Curious if a little more voltage is all the CMK32GX5M2B5600C36 5600mhz needs.

Thanks for your help.

It's Samsung DDR5 16Gb B-die (I guess there was some previous versions that failed).My Patreon: https://www.patreon.com/buildzoidTeespring: https://teespring...

How warm are the DIMMs under that voltage?

In the summer they were hitting 54 now with 25 ambient they peak at around 48c. The voltage isn't the main culprit for temps, it's the command rate and trefi. I have it at 65535, cause maxed out at 262000 the dimms hit over 60c even with low ambient

I got close to this however in one particular game it would crash out constantly where as every other bench and game it would pass no problem. In Star Citizen, no matter what i did i couldn't get 1T on the command rate to stick, it would crash, i even had to loosen my timings for 6000mhz to work!

I had it upto 6400mhz with a relatively tight timing and 1T to stick on the latest bios no problem, passes all benchmarks especially Y-cruncher but in Star Citizen it would crash.

Pretty much the same as Bencher, would sit around 50-55c for me but during benchmarking i've had them as high as 80c so had to put a fan ontop to cool them through tests.

You can get 6000mhz with very little work but as mentioned above its abit finnicky with some particular games. I've had it upto 6400mhz with tight timings and ran okay no errors but crash in Star Citizen but nothing else.

That's impossible. Did you stress test them with something like TM5? If they pass TM5 anta extreme then it won't crash on any game.

No not TM5, not that i recall anyway. I need to look into it again at some point as i haven't messed with it since getting 6000mhz stable in everything i play. Would be nice to tighten the timings abit more tbh.

Can you tell me the configuration you used for 6400 (times, voltages etc...)

Will need to take a look at my settings again, it's been awhile! Let me get back to you later with some settings.

Tendré que echar un vistazo a mi configuración nuevamente, ¡ha pasado un tiempo! Déjame contactarte más tarde con algunos ajustes.

te agradezco hermano

I just tried this setting also and apparently it works! Before I ram 6600 Mhz 36-36-36-96 .. I have not yet compared them.

But I was wondering what is your tWrc? Mine default is 90 via XMP 2. But im thinkin it can be lowered with -58 tRas.
