Faulty i2500k

[magicmutley]

Hi

Been having problems overclocking my i2500k CPU so someone suggested I run Prime95 at stock.

Ran Prime95 for 8 hours and one of the cores had an error.

Had the following error on Core 3:

FATAL ERROR: Rounding was 2.213541735e+020, expected less than 0.4.

So, 1 error in 8 hours...does this mean my CPU is knackered? Would explain why an OC fails everytime I guess if it can't even stress at stock.

Can I return this for a replacement or is there some weird tolerance disclaimer from Intel?

Test your RAM first, also, what's your PSU?

 

[El Jimben]

Are you running small FFTs? What vcore are you using?

 

[magicmutley]

Sorry really should update a signature.

Using a Cooler Master Silent Pro Modular 700W '80 Plus Bronze' Power Supply and Samsung 16GB Green RAM.

NO not tested RAM yet, maybes do that now :/

Used IN-place large FTT and VCore is set to AUTO in BIOS

you proberly just need to set the v core a little higher to get it stable

Test the RAM with memtest86+ then come back to us.

Being a bit dumb here, but surely the BIOS defaults should be OK for stock speeds, like I say 1 error in 8 hours is not the end of the world but a bit cheesed off it will not overclock

HAVE YOU TESTED THE RAM???

HAVE YOU TESTED THE RAM???

Ran Memtest86 and no errors.

Ran Memtest86 and no errors.

How many passes?

 

[magicmutley]

Did 1 pass as it took nearly 70 mins, someone I know suggested re-installing Windows which I did and seems to be working OK (for now) clocked at 4.2ghz....

Gonna run Prime95 overnight
