Figure out what killed my i2500k(ASUS Bios bug) - Page 3

post #21 of 33
this happens every time you switch from fixed to offset mode (bios bug),that's why you need to open up CPU-Z as soon as you boot up
there is absolutely nothing wrong with offset mode and i love it
@tats.. yes you idle @ 1.024v 1600Mhz and 1.368v 4.7 under load
or around 1.1v 1600Mhz and 1.45v 5.0 load

What llc level do you use?

LLC have a lot to do with it (to high ,it won't be stable in idle/light load)
what are you shooting for? 4.7 or 5.0 ..my chip need similar voltage ,i can give you some settings

Scary.. My i5 2500K arrives probably this friday, so I've taken notice of this. Thanks for the information.

if you use offset voltage when your cpu is at idle clock 1600mhz your voltage will undervolt to 0.928v and if you use manual voltage your voltage will stay same as you set it.

is asus going to fix this bios bug?

Now I'm glad I went with Gigabyte this round.
post #26 of 33
I actually did realise the same thing happen a couple times, but I always made sure to double check the settings before applying it. It is apparent like you mentioned, that switching between profiles that the voltage does somewhat get altered. As you have pointed out, this bug is very dangerous and I do always recommend checking settings before applying but nevertheless this bug should be a top priority for asus.

Don't mind if I link this to a thread. This information could be very handy to a lot of people with asus mobo's

Thanks for the heads up.

EDIT: what bios was you running?

Happened to catch it last night before I saved and exited my 5ghz +.105 offset, the offset was actually at +.975v.
Had I not checked...

So be careful and always double check the offset when switching saved profiles.

a similar thing messed one of my 2600k up.... but i was using a fixed voltage and it shot up to only 1.78v

is the chip still functional?

He was overclocking, but between changing profiles in the bios, the bug caused the voltage to increase substantially causing his old cpu to die. He only noticed the Asus bug when he did the same thing with his new chip, but this time before applying the settings in the bios he changed it to an appropriate value rather than 2.0v+

Thanks for info Grunion. It might save somebody from accidentally killing their shiny CPU.
