CPU-Z and Ryzen Master showing different RAM Timings than BIOS is

I have a Ryzen 5 - 1600x Processor, ASRock AB350 Fatal1ty Gaming K4 Motherboard. G.Skills Ripjaws V Series DD4 8x2 GB 3000MHZ C15 sticks for memory. As most people with new Ryzen's, I've had issues getting my RAM to go up full speed. It was 2133 MHZ for quite awhile, but it seems like I can finally get it working under 3000 MHZ with these new timings, but I still am getting infrequent errors so I don't think it's 100% stable. I was using the timings of 16 CAS, 16-16-36. Then I tried to update it to these timings.

In the BIOS, I've got my timings set to 15 CAS, 16-16-35. I've also set the Command Rate to 2T. I save, I load into Windows. CPU-Z and the Ryzen Master OC tool both show me as having the timings of, 16 CAS and 16-16-35. CPU-Z also shows me the Command Rate as only being 1T.

Is there any reason for the discrepancy? As far as I know, everything is up to date.

  1. Are you looking at the memory tab of CPUz?

    Yes I was.

    The memory timings seem to work flawlessly for World of Warcraft, never had a crash in that game. But Overwatch, it'll have a memory related crash anywhere from 5 to 20 minutes within launching.

    Still don't know why CPU-Z would show different timings

  3. For reading timings, use another program like AIDA 64 or a benchmark test to see what the tested values.

    As far as the crashing, have you tried individual sticks to see if the problem occurs with each?

    I have not. How would I do that? Would I just pull out a stick physically and see if the other works with no issues or is there a way to disable a stick without removing it physically?

    Ok, I downloaded AIDA 64 and I can't see the Command Timings because of the trial edition, BUT it does tell me the same thing CPU-Z tells me. The timings are 16-16-16-35 according to AIDA 64, but my BIOS says otherwise.

    Have to physically remove it, then test and see if one module performs differently than the other. By isolating the sticks, they are forced to run on their own, so if there is any problem it should be apparent.

    Do you have the latest BIOS for the motherboard?

    Load BIOS defaults then try again. If possible, hard reset by shutting down power completely, Let us know how it goes.

  6. I also have a ASRock B350 motherboard although mine's a slightly different model. I had some similar problems when I first built my pc.
    Firstly, make sure your sticks occupy the 2nd and 4th ram slot positions only. Secondly, my ASRock B350 mobo will only allow me to enter an even number. I know this from experience having tried entering 17 and 15 for CAS latency and when booting back into BIOS finding the real value to be either 18 or 16 respectively despite the set values still being displayed as an odd number.
    Does your motherboard have a similar function to show set and real values?
    If so maybe you can find out if the problem is the same as mine
