Title: B350m Bazooka Vcore
Post by: nepatsallday on 06-February-18, 18:19:20
I updated my MB to the latest bios, 7A38v1A, and now my Vcore hovers around 1.45v in the bios. I have reset all everything back to default and reflashed. Stays at 1.45v for 20-30 seconds before dropping to normal range and then right back up again. Also, according to HWinfo it spikes at 1.52v. When I attempt to manually set the voltage to 1.3 volts, because now it wont allow the voltage below that, it locks my PC up on boot. It will only allow me to run the voltage on "auto". Is anyone else having these issues and is it possible to downgrade the BIOS?

Ryzen 1500x
Msi Bazooka
Team Dark 2400mhz
EVGA Gtx 1080

I’ve reset the cmos and not sure what else to do. Any help would be appreciated. I’m afraid I’m going to damage my CPU and/or MB.

I updated my B350 Gaming Plus too and can't go bellow 1.3vcore also i was at 3.7ghz with 1.2375vcore since i can't go bellow 1.3vcore i bumped the speed to 3.8ghz with 1.3vcore seems stable and all good, something im really happy is that now my Gskill Tridendz 3200cl16 now work at 3200mhz and before could go past 2666mhz.

I may have found why it was spiking at 1.4 and 1.5 volts. This bios update apparently makes the core performance boost hate the motherboard and tries to destroy it. I turned off core performance and voltage stabilized. But after turning it off now the voltage drops from 1.265v to .85v before rebounding. At this point I’ll take it. At least it won’t burn my motherboard up. Hopefully some of these issues are ironed out soon.

Hi

As far as I am aware, MSI made minimum voltage to be 1.3v. I do not know the reason for this though.

This is an obvious problem with the new BIOS, even if you did the voltage to the core 1.3 volt default with senseless dissipation at default frequencies, then call the default DDR voltage 1.55 volts, in my head. Do you have any idea how many memory modules will fail in humans who won't pay attention to it?

What board are you running that you have DDR voltage as 1.5v in default? Is it B350M Gaming Pro by any chance?

Yes, it's B350M Gaming Pro, I understand the whole series B350 has a similar problem with a new BIOS

Yes it is B350M Gaming Pro
Ok, it's a known issue, and we already got BETA if you'd like to try. It apparently fixes DDR voltage.

Im just curious if the vcore issue im having on my Bazooka as stated above is a known issue? Whether the core performance is turned on or off the vcore appears to bounce all over the place. I'd rather it bounce very low like it current does than bounce all the way up to 1.52v like it was with core performance boost on.

No. Known issue is 1.5v on DDR on B350m Gaming Pro motherboard which we already received BETA BIOS for to fix it.
Unsure of this vcore spikes to be honest. Might get more information about it later on.

Ok. Thank you for your quick responses. I'll continue to mess around with it and see if I can find a solution.

first of all i had a very same problem with sa and io voltages , 1.35. is not great at all ,with latest bios v4 this has been fixed and the voltage needed has been lowered a lot on both sa and io .as for your memory and xmp ,ive had trouble in the past with g skill memory and found very temperamental and often, xmp would not work .is your memory on the qvl list of compatible tested memory on msi site and on g skill site .ive had said compatable memory not work with xmp ,and found it is the memory module at fault not the motherboard .i changed to team memory and have now no problems at all runs xmp as stated overclocks better than g skill in my opinion.xmp works on setting it .if no xmp runs at 2133mghz as coffeelake max is 2666mghz and thats why the voltages went high on sa and io.but now msi have fixed that and the default voltages are much much lower so there is mjuch more headroom for overclocking memory .i have 8600k sli plus team menory dark pro 3200 mghz

This has nothing to do with AMD system
