HELP! 2700X voltage(manual) out of control
Before I start here is my system:
2700x -Asus Crosshair VII
Standard WraithPrism Cooler
1250w platinum g.skill PSU
32gb DDR4 3200 g.skill
Reference Vega 64 x2 in crossfire
1tb ssd/2tb HDD
(Skip to 3rd paragraph if you want to get to the point please)
This began with the usual gpu OCing(still need help with this too) I'm newer to computers but feel I have had my fair share of enough research/playing around to be well enough off.
My GPU seemed to always have slight microstutters (this is with crossfire totally disabled because I am only tuning my primary card since most games dont seem to work with crossfire..) the GPU usage will drop a few % like down to 95% that is where the stutters occur. Even setting GPU back to default this still is happening. So I was in bios the other day looking for a way to slightly enhance my CPU gains cause I was looking around and read people saying cpu bottlenecks could case these usage drops.
I went into bios where all my settings were unchanged. I had manual voltage set to 1.375v, LLC level 1, standard DOCP xmp settings, nothing much else was different. But back to the point I was in digi+ power settings and saw VRM Spread Spectrum settings which were set on auto. Asus' definition of this setting was turn to disabled when OCing. So I figured hell this is a OC feature maybe by disabling VRM spread spectrum it would unleash my VRM capabilities and enhance the standard XFR2 boost clocks without me messing with any other OC enhancements. So I disabled the setting and didn't touch anything else left it all how it was with manual voltages etc.
When rebooting the system I opened up gpu-z, AMD RyzenMaster, Heaven benchmark, and radeon wattman. Started fresh and set the GPU back to default (aside from my fan curve) to re-do the OCing process. Started heaven and very soon into the process I noticed my CPU temps into the mid 80's. I have always had an aggressive CPU fan curve to keep my thermals below 55c never really would go above that. So, immediately I stopped the benchmark and waited for my temps to cool down while monitoring my CPU. That's when I noticed XFR2 taking rein and going all over the place. My CPU sure did boost higher, but my voltages were spiking from 0.875 all the way up to 1.6! Going up/down - simply said voltages were bouncing way too high. - keep in mind I still had my voltage set to manual 1.375 and made no other changes. Before this my CPU would stay 1.35-1.375 all the time no crazy up down or over my manual set limits. After seeing this I went back into bios immediately and turned this feature back to auto like it was at default. When booting back up went into my monitoring tools again and ryzen master was showing my typical 1.35-1.375 like I had set. Until about a minute into monitoring it did the same thing. Bounce up down & all the way up to 1.6v. Not cool so I restarted again went back into bios went to that VRM setting again and switched it to enabled from auto. (So it was on auto to begin, went to disable, had this issue, went back to auto after issue, still persisted, so went to enabled as to turn the VRM throttle back on) problem still existed.
So I've spent the last 2 days screwing with bios trying to fix this. I have cleared cmos, reset, loaded optimized defaults, rebooted on default settings still persisted (ofcourse that's xfr) then restarted back to bios re-set my manual voltage - still persisted, have turned off auto performance enhancer - clocks stayed at 3.7 with 1.1ish voltage but after the minute again it would drop voltages then boost back up to 1.45-1.5 ranges just to get it to boost back to 3.7 ghz. I have tried everything in the world I can think of to set my voltages back to manual like it was before where I had none of these bouncing around issues. Have set llc to 1, turned back to auto, set it to 2, still no change set back to auto, have limited my cpu current to its 100, have tried limiting everything that relates to power so I can try to get my system to stop over volting and still it's doing the same thing.
Why cant I get my voltage to go back to my normal setting of 1.375 and not pull any more than that. I have never had this voltage issue before hand when I had it initially set on manual and I'd leave all the performance enhancing on auto like it is at default and my system never pulled more than its 1.375.
But now after turning that vrm spread spectrum feature off I can not get it to go back to my manual voltage no matter what I set for voltage or settings.
Is it my chip? Is it my mobo? How do I fix so I can set my manual voltage once again to it's fixed ratio and not have any overvolting above my set limit.
