Have you bumped Vsoc and/or Vttddr?

If you are asking me, the answer depends.Have you bumped Vsoc and/or Vttddr?
I agree, that is why I use Blend with prime95 v28.10 for reduced temperature do to increased memory usage..If the workload fits in the cache or not depends on the FFT size. For "large" FFT it certainly doesn't fit in the cache, and will stress the ram. For "small" FFT it does fit in the cache, and stresses the execution units more, but not the ram.
Also note that the release versions of P95 (28.xx) don't detect Ryzen correctly, and doesn't use FMA3. There is a test release of 29.1 at link below if you want to try an updated one. The CPU detection is updated so it handles SMT now, and it can use FMA3 transform. It seems to give slightly higher benchmark numbers than Bulldozer/K10 it was using in 28.xx.

This is not abnormal at all. Many different platforms do this all the way back to socket A.But if there was a thumb drive left in the system after reboot it would always try to boot from it regardless of boot settings in BIOS.
That's because there isn't any setting to change. That's also why there are two different BIOS versions for the C6H board -- one for 1T and one for 2T. They haven't enabled user choice in the BIOS (yet).I've never seen the 1T command rate on my 1700X and Prime X370. Always has been running at 2T command rate. Haven't seen anyplace to change that in the BIOS. It just seems to pick that on its own. The G.Skill F4-3200C16D-16GTZ is running at 16-16-16-36-56-2T @ 1.35V

It can set the command rate I believe, but mine is always stuck in 1T. Sticks are rated for 2T :/I was replying to BlueFalcon13 because he stated he has only run at 1T on his Prime X370. I was wondering how he did that. Does an XMP memory profile also set the command rate? I thought it only did timings.
Thanks. I knew that you can see the command rate in various utilities, but I always thought it pulled the information from the motherboard EC and that has been set in previous generation motherboards in the BIOS. Didn't know it is defined in the embedded SMP chip in the DIMM.
Mailman just showed up, 15 minutes before his 5 PM quitting time. Now to try out the new Corsair 3200 CL16 memory. Wish me luck.
XMP on the memory does set the Timings and sub timings. What the motherboard Bios sets for other settings is a different story.I was replying to BlueFalcon13 because he stated he has only run at 1T on his Prime X370. I was wondering how he did that.

Yes, I can't change anything related to command rate in the BIOS, but the new Corsair sticks are running at 1T versus 2T on the G. Skill RAM. Stock XMP settings for the Corsair 16-18-18-36-75-1T.
How is your memory working on the Asus X370 Prime? I would RMA the Gigabyte Gaming 3 to the place of purchase, Woomack is not having that problem with his.
Haven't tried that yet. For a LONG time I've just moved this 27.9 P95 folder (portable zip extraction) from one windows install to the next. I just wasn't sure what I should be using to stress test at this point cause everyone keeps saying P95 is overkill and too heavy of a load to test with...
Oh yeah, I know. The reason I call mine a dud is the voltage. Most that hit 3.8GHz can do it on 1.2v or so while mine requires 1.351v. Mine can only do 3.65GHz on 1.2v.
My 1700 is running 3.7ghz @1.1875. stock cooler or I would look for the limit [emoji14]Personally I'm a little doubtful that most chips can do 3.8 GHz on 1.2v. 3.7 GHz on mine requires 1.2125, and even that is reported as actually being 1.245v in CPU-Z (probably due to LLC setting). For people claiming to hit 3.8 GHz with only 1.2v, I take it with a bit of a grain of salt. Some might have a good chip, some might not have actually tested for stability (some people's idea of stability testing is to run a few tests for 5-10 minutes, and then see that it doesn't crash in games), some might not realize their motherboard is applying an LLC setting which is pushing their voltage up much higher than 1.2, and so on.
This is not abnormal at all. Many different platforms do this all the way back to socket A.
Has any one tried keeping stock memory speeds and getting tighter timings vs going for a higher clock speed? Curious if timing tweaks result well.
