Memory clock on Asrock X570 Creator

Thanks so much for your suggestions. I've actually had a little bit of success, and I'm not quite finished. Just doing experiments bit by bit like you suggest. But it takes time to adjust, then reboot, the fire up CPU-Z/benchmarks etc.

So far I've managed to clock ~3120MHz by doing this:

* I removed two of the DIMMs as your suggestion that x4 totalling 128MB could be the problem, (using slot 1 and 3, total = 64GB now). I'm not yet using the full 128MB yet so this isn't a big deal.

* I loaded the XMP profile for 3600MHz, so I have all the 3600MHz timings including 1.35V. However I changed the frequency to 2666MHz, then gradually increased in steps to ~3120MHz. At each step, CPU-Z is finally recognising the new clock speed and timings.

Unfortunately I was not very scientific in the approach (i.e. changing one thing and testing), so I don't know if:

? If 3600 will work with just two DIMMs, but I can try this easily later
? If removing x2 DIMMs helped, or if it was the frequency adjustment

So either way, I'm in a much better place than I was in yesterday. So I will keep testing and report back. Interestingly my memory is not listed in the motherboard QVL at all, yet it would seem that 2x32GB works and is somewhat overclockable.

Thanks for your continued support and help!

I would think 3600mhz is highly possible, just the timing needs lots of manual editing,

I think you can probably leave all the secondary sub-timing on auto, just use very high, very slow, very loose primary timings,

something like 20,20,20,20,40,60, and start at 2800mhz, then 3000mhz, then 3200mhz, 3400mhz, etc

record write on log book to collect failures and slowly you will see a pattern....

The problem is that even though in the BIOS it shows that my memory is clocked according to the XMP settings, the adjusted timings do not appear to be used. Perhaps this is due to the limitation you mention. Hopefully the images here will show it. Anyway, I will keep trying like you suggest, although not sure what options I really have from here.

Hi again,

Sorry to break this to you, but there's so many criteria and rules, this one is limitation, Ryzen 1000


Ryzen 3000 is higher but it was not meant to run all 4 dims plus all dual rank at 3600mhz, this will be a big big challenge, i.e. the true effort of overclocking the timings + voltages + mhz, etc

The 2666mhz that you're running, probably is default, using 1.2V dram voltage and soc 0.9V or something low? If I'm correct then your XMP is not working at all, most probably because of the inherent design-in limitation, plus ram XMP incompatibility with motherboard etc etc etc.

as for where to start reading, just try "stumbling" onto it, anywhere, everywhere, keep fiddling, keep trying.

if we're on VOIP, may be I can talk you through easier, but typing is too much, sorry.

tips, write down on a piece of paper to spreadsheet the results from calculator and compare results of all PCB version A2 vs A0 vs manual vs bad bin then find all the biggest numbers, theoretically this is least demanding and could possibly boot, but there's so many rules some parameters must be this formula and match with that etc,

only after comparing on paper all the possibilities plus trial and error you will slowly find better and better timings etc.

also start low, like your 2666mhz with very low tight timings to get latency lowest as practise start. then up 28000 then up etc. this way you also find out the few timing always fails and how many additional number you need to add etc etc.

I'm if you tell more, more people will help out, the info you provided is not enough to give advice honestly.
