ROG Crosshair VI overclocking thread - Page 896

post #8951 of 17358
What do you guys need for 3.6, 3.8 and 4GHz? Who tested these values specifically?

With my Ryzen 7 1700 I need for primestable settings:

  • 3.6GHz@1.11V
  • 3.8GHz@1.24V (still testing if less also works)
  • 4GHz - not even doable with 1.45V

So my CPU runs pretty well down low but up top - oh man. There's a reason why this thing didn't become a 1800X. I still get extremely efficient operation at 3.6GHz and lower, the CPU draws about 75-90W in Prime95 according to HWInfo64 and runs at 43°C (with Sense MI Skew disabled).

I just wanted to try P state overclocking again, but BIOS 0081 refuses to save any changes to P state that I make. It doesn't even show up in the changes summary when you choose Save and Reset in the BIOS. Did I miss something?

Running my 1800X @4Ghz 1.385v
4.1 did work from Ryzen Master @ 1.4125, but did not manage to boot on it.
Have not tried higher voltage for 4.1, running at 4.

Thanks, did someone test the other settings as well? I would be interested in what you guys need for like 3.6 and 3.8GHz.

1. Didn't test 3.6GHz.
2. Higher than yours (1.381v and 1.362v -- I have two 1700s).
3. Same results as you.

I use IBT AVX Maximum for stability testing.

AMD CBS changes never appear on the list. You just need to make the changes and save and exit - they WILL apply assuming you did it right. You can verify by going back into the BIOS and looking at the speeds and voltages on the right side.

Have not tried higher voltage for 4.1, running at 4.
If it's a consolation, I could boot both 4.1 and 4.2 GHz, but they are not stress test stable.

I know what my crappy chip needs to be stable by now. Guess Need to set LLC2 and keep bumping +offset voltage till i get 1.42x after vdrop.

Finally gotten to full stable setup yesterday and what did the trick in my case was bumping VDDP from 0.915 to 0.960. More VCORE SOC VDDR PLL was doing nothing. Bumped that 2 notches and passed 9 hours prime blend2 hours realbench 3xibt max and AIDA. Left it rendering 4 hours of 4k footage from my gopro as final test. Since as i mentioned on X99 i could pass every stress test for hours and yet still crash when producing my test video :/

I doubt you'll be able to overclock a 2400 rated kit to 2993.

I would've gone with that one if I was forced to get memory from that store. 3200 MHz, G.Skill TridentZ. But note that they are 44mm/1.73 inches tall so you make sure you have clearance for your cpu cooler.

I had to pay 555 CAD for my 32 GB, 3200MHz, CL14 RAM. It's actually my most expensive component. Hoping it'll pay off..

Of course, there is nothing too exotic though:

- cpu multi 39.5
- cpu voltage 1.375
- LLC 3 (will try to lower it after what I saw on this topic yesterday, but it's not easy since with LLC auto I need more than 1.425v to get it stable)
- 3200 ram multi
- timings 16-18-18-18-38
- Ram voltage and ram boot voltage 1.4v

Anything else on auto/default with bios 0083.

Note that after trying to bump the bclk I had also a problem: even when back to 100 my ram was rebooting at 2133, I had to clear cmos. Also yesterday back from work I noticed that the computer booted twice, it probably had to train ram again. But everything stable while gaming and benching at 3200.
