Tell them it has a coldbug, although AMD does not warranty overclocking, they love it when people tell them they are doing super overclocking, this has worked for one of my friends, his 1090T had nothing wrong other then being a poor overclocker, he told AMD he was entering a contest and was going to be using LN2 and that the CPU had a cold bug, they RMAed it for him.

im dead serious lol. i went through 3 of these chips before i finally got one that would go over 4ghz. the rma department for amd is a joke. i explained my issue, of course i never said i was overclocking. just that the cpu was having abnormal temps with the stock heatsink. they never asked any other questions those 3 times i submitted an rma request. so on the 4th time, i got my magic cpu, and have been able to hit 4.2ghz.

heres my proof.

My 1090t gets up up 4.1 before becoming unstable its just the luck of the box LOL
post #16 of 27
Mine can hit 4.0 and 3000 NB. I can hit 4.2 with two cores disabled. I am using the 990FXA Gigabyte UD3 board. Getting ready to put on Ebay this week though since I have an Intel setup coming.

I can get to 3.72 ghz at 1.325v but for that 200 mhz more i need 1.125v and cant even manage 4ghz

could be your ram. higher frequencies tend to put more stress on the cpu (adding more heat for example). Try running at 1333 or less.

My 555 takes 1.5v to reach 4GHz.

My 1090T was kind of the same.. until i bumped the NB voltage and frequency. Now im at 4.12 at 1.43V.

Not to derail, but you have much to learn in the way of the overclock

1100T @ 4.1ghz
16min 59sec
1055T @ 4ghz
17min 20sec

But what does single thread stability matter?
