Good evening, i picked up a very cheap 32gb 6000mhz cl30 kit (other timings are poo)
i was very cheap so i thought i would grab it to play with.

i have never done any DDR5 OC, the sticks in my AMD rig are set to expo and left alone as there was the big AMD ram cpu killing thing

KIT: ADATA XPG Lancer Blade 32GB DDR5 6000MHz CL30 Desktop Memory(single rank)
Running 100% stable at EXPO setting

i will test with TM5, any advice on what to do.. do i chance Mhz or working on timings
What is a good voltage for DDR5

How long is a piece of string?

It depends on the die used for the memory chips and so many factors.

You could try 6200 or 6400 for better gaming but I'd wager that improving sub timings would be a huge uplift in performance and something you should do first.

I'll see if there's a dedicated DDR5 overclocking guide for you to follow.

Could also look at buildzoids videos on youtube, he has good info on overclocking DDR5 on both Intel and AMD.

Buildzoid is very good for RAM overclocking.

I will read the guide myself because I’ve not got any DDR5 to play around with but it will be fun one day.

I would like to get a motherboard that has amazing RAM overclocking (gene, Unify-x, tachyon, etc)

I’m hoping to get an Intel rig in the future.

how many sides on a die

This is a great starting point, for pretty much any DDR5 regardless of IC's, ive ran these timings on M die and A Die......if you can stay awake and will improve performance quite a bit.

Jump to 4mins.10 if you want to get some of the babble out of the way and get on with it.

EDIT: SOC voltage is not safe upto 1.4v as per the video, max safe is 1.3v and also the FCLK being fastest at 2033mhz bug was fixed, so its no longer the case, keep everything 3:3:2 so 6000mhz ram = 2000mhz FCLK.

well this just worked. stable and zero errors.
i dropped the main timings the other days and there stable with this set of timings.

only steerability testing over night. ill run some bench marks latter. but i cant see it been slower

The only timing that I find doesnt scale with voltage is tRCD, watch out that you dont try and lower that one too much, your probably just better off leaving it at 40, mine is stock 38 and set to 37, it gives errors if I lower it to 36.

Ive posted this many times, but this is currently my A-Die im going to push for CL26 later today, I need 1.5v VDD though to keep this stable, but im happy to push 1.6v, the starting point for this was Buildzoids video that I posted above and a little bit of help from guys on another forum, notice GDM is disabled, it gives massive improvements on latency, but its not easy to tweak, most of the time it leads to no post and bios resets.

This is quite an old picture now, things have been tweaked further since this and voltages reduced.

i ended up running the BZ timings for a bit they was stable.

but then i want back to XMP i nipped up the 2nd and 3rd timing but not as tight as BZ said, and i set the ram to 6400Mhz it been there for a week with no problems passed a few runs on TM5
Today i set the ram to 6600Mhz again with the same timings i have been running for a week or two now. TM5 is running now but showing no errors as of yet

Are you running 6600mhz 1:1 or 2:1 ? have a look at UCLK in HWInfo, or the UCLK speed in the Memory tab of CPU-z should be the same speed as the memory speed, if its half then its not worth it, drop it back down to 6400mhz, it will be way faster., 2:1 isnt even worth bothering with until your pushing 7600mhz+ andd even then 7600mhz is the same as running 6400mhz 1:1.

i genuinely don't know it was set to auto but the CPU is locked so everything base base(5200Mhz) speed would not be 1:1 would it?

All Ryzen's are unlocked, this is what 1:1 looks like, so at 6600mhz your DRAM Speed a UCLK speed if 1:1 should say 3300mhz, if your DRAM Speed says 3300mhz but your UCLK says 1650mhz then you are in 2:1.

Which motherboard do you have, you can force 1:1 but if you can get 6600mhz stable 1:1 then you'll pretty much be the first ?
