Yes smile.gif .

My R7 1700 is 1.1875V for PState 0 VID, I would like to make it 1.356V for my FID of 3800MHz.

Only option for me is changing FID in PState 0 and applying either manual or offset voltage on Extreme Tweaker to reach the CPU voltage I need. I don't use OC SW and prefer setting up OC in UEFI. So if UEFI 0003 is allowing VID change in PState 0 for an increase I may try it smile.gif .

It seems I misread. I'm on 0003 but stopped attempting to change VID in bios several versions ago. Not sure why one would need to change VID and use an offset at the same time.

Might re-test IBT and play with VDDP and SOC voltage.

Digitalfrost, I set my SOC to 1.15 via offset. I'm using the Gskill FlareX DDR4-3200 CL14 ram 16g (2 x 8). I set the Overclock tuning to D.O.C.P. standard which sets all the 3200 parameters in the BIOS automatically. As I said I find setting SOC to 1.15 manually gives me the best stability.

As to my cpu it is a 1800x so I suspect it should be a bit better for the price. When I run IBT it works at P0=40x only if I set the voltage to a minimum of 1.3925V. Below that it reboots. I set the clock to 40.25 and needed 1.4125v to pass.

Right now my system appears solid at P0=40x at 1.3925v. I have BLK at auto.

BTW, I really appreciate the feedback on this forum especially from the OCers with the 1700s.

Having a 5960x rig which has an incredible OCing potential (or Intel intentionally kept it low) to now working with Ryzen shows me that AMD released a cpu that is just about at it's max without much OCing headroom.

What is funny is that my $499 1800x at 4Ghz via Zenstate OCing is scoring almost the same Cinebench 15 score (1763) as my 5960x at 4.4Ghz (1758). In Aida64 CPU Queen the 1800x is 92774 while the 5960x is 98790. In memory remember the Ryzen is dual channel while the 5960x is quad. I have 3200 memory for the Ryzen while I kept the 5960x at 2133 for stability.

In Aida64 memory read the 1800x is 48929MB/s while the 5960x is 59880MB/s.

Of course I sent @$1000 for the 5960x and @$450 for the mb while I spent $499 for the 1800x and @$260 for the mb.

After verifying again that my CPU won't post with increased baseclock below 104.8 I again tried to get stable with this. Memory errors are not a problem but my Fury X absolutely does not like the higher baseclock. With some increase in VDDP I could get it to just BSOD instead of code 8 most of the time but in the end only lowering to PCI-E generation 2 for the 16x slot fixes this. I increased VDDP up to 1.095V, not sure if I want to try any higher.

But the lengthy freezes during RealBench reappeared to some degree even though they were mostly gone after the power plan fix. Guess this is somewhat related.

Furthermore I do not specifically disable Core Performance Boost and do not see my CPU change frequency higher than what I have set in BIOS (neither using fixed OC or using P-state OC). Frankly, I would be happy if it did that, because then it would use 4.1 Ghz for 1/2 core tasks instead of just using 4.0.

On a side note: I just passed 10 loops of ITB AVX at 4.0 + 3300-CL14 after decreasing SOC to 0.95 V via offset. Let's try to lower VDDP a notch more and then see if I can squeeze more power-saving out of it during idle times (60 W idle still is a bit excessive wink.gif).

Maybe its some limit on BCLK then. Im on 118 wont work. It works on 100 and i know it wont work at 104.

Ok, I solved this. Using BIOS P-state VID higher than 1.35 (20) does not work, it will also fail to OC then. What *does* work, though is to use *any* offset (smallest is 0.0006) and then use ZenStates within Windows. The offset step is necessary, else ZenState doesn't work (neither for frequency nor VID).

This is why ZenState worked when I tried it earlier, which in turn made me post that it works for me. wink.gif

Negative SOC offset seems to get me into trouble (re)booting. I get Code 02 and D1 (upon reset) errors. My suspicion is that during early boot SOC is lower than the later 1.15 V Auto value, so my -0.15 V lowers it further down to instability.
post #11568 of 17534
I'm really looking forward to having higher memory multipliers available, seems my CPU & memory can do at least 3400 cl14 without additional voltage increases. Increasing BCLK has to many side effects for my system atm.

Anyone got an idea why the same pstate & vcore offset settings result in different voltages when increasing the base clock vs. Auto? What would normally get me 1.425V with an 0.075V offset only yields 1.25V when BCLK is increased. Guess I have missed some info there wink.gif

I do get 1.425 V with a +0.075 V offset, but my RAM OC also fails once I step from 103.2 to 103.4 BCLK. So maybe that Vcore change happens with that step and I just didn't notice the drop?!
post #11570 of 17534
I only noticed once I stress tested and got code 8 errors instantly. HWiNFO reported very low core voltages.

Did you try stepping a little further above 103.4? Or do you want to keep it on the low side? Maybe you got a memory hole a little above the one I noticed with mine.
