CPU @ 1.55v

[BluD]

Been getting crashes in GTA all day, thought it was a bit odd so i flashed my GPUs with stock bioses, disabled my overclock on the CPU and updated graphics drivers.

No joy got another crash so i downloaded hwinfo and ran a stress test, i noticed the CPU temp sitting at 75 and even spike to 85 degrees for a second which is like 30 above its normal temp, checked the voltages which read Min 1.55v Average 1.55v Max 1.55v for the vcore. I restarted to bios to double check and in the bios it was reading 1.5v and thats with is set to stock voltage with no offset. Normally i have a +100mv offset for my overclock which means it could have been running at 1.65v causing the crashes.

Now the question is WTF!!!!! I havent changed anything, updated anything(maybe windows updated itself) or changed any overclocks, so why the hell would it suddenly feel its a good idea to increase the vcore to such a high lvl. I dont have any overlclocking software installed or any mobo rubbish, just AB for my GPUs.

Anyway, ive reset the bios and everything is running normal and the temp is maxing out in the 40s again.

Strange one ey?

Intel needs your cash- built in upgrade hints

Reset bios and start again.

Or aliens.

It cant be aliens, they always tell me when they're coming to visit.

Cool just found my CPU has been running at 1.51v all night again, no idea when it changed but ive been on gta most of the night, no crashes or anything so 1.51v must be ok, it just doesnt like 1.55v or above. I bet im gonna start losing my 4.9 overclock soon if it keeps overvolting, it will have degraded too far.

Anyway, looks like im gonna have to reflash the bios to try and stop it, im gonna go back to the old revision just to make sure.

1.5v is surely way to high? Your temps must be through the roof?

 

[BluD]

Luckily with the chip been delidded the temps dont get that high. At stock voltage it barely makes it out of the 30s under stress so even at 1.5 its still only in the 70s.

use manual voltages?

 

[RobertN]

update the mobo bios maybe

 

[BluD]

use manual voltages?

Yeah i use manual voltages

update the mobo bios maybe

I was on the latest bios, im trying the previous revision instead. I suspect a crash had just corrupted the bios, my old z77 gigabyte board used to corrupt its bios now and again, its the reason i ended up changing to z97 and giving away all my 1155 stuff. I obviously didnt want to sell it even though i had bought 2 new bios chips for it.

I've dropped my overclock to 4.7ghz now and its not crashed since so i suspect the high voltage has knocked a couple hundred mhz off the top end of the chip through degradation. I'll leave it on 4.7 for a week or so and if i dont get any crashes ill try 4.8 then repeat for 4.9. It might all be fine yet.
