Is my 1090T CPU faulty?

post #1 of 29
Thread Starter 
Just wondering what you guys thought about the voltage I am getting with the 1090t.
(Voltages monitored with CPUZ)

At stock with bios set at auto, the chip is running at 1.4vcore (23c/37c stress)

Once I started overclocking:
At 3.8Ghz, I had to use 1.47v to get it stable and run prime95 without problems.
At 4.0Ghz, I had to use 1.51v to get it stable and run prime95 without problems.(26c/45c max stress)

Comparing these voltages to what other people are having to use to hit these points, it seems a little high. Faulty chip? Bad Mobo? Or did I just get a chip that likes more voltage or am I missing anything? Any thoughts would be appreciated. Thanks.

No it's fine.

Every chip is different.

Yours just needs a little extra juice.

high volts, but I think is because of your mobo.
What is your voltage at full load?

Well at 4.0ghz my voltage actually drops to 1.47ish from 1.51 while stress testing according to cpuz.
At stock speeds the voltage dropped from 1.4v to 1.37-1.38v.

Only a 4 pin EPS 12v? Seems like a bad idea for an overlocked Thuban.

At stock speed your volt. is 1.40?
Mine is 1.30V(mobo sets it... @ AUTO)
Did you try to OC just the CPU with everything else @ AUTO? Still needs 1.51V for 4 GHz?

Yes needs 1.51 to run prime95 without locking up with everything else stock. Yes 1.4 stock as it reads above

Could my motherboard be the problem? Thought it was a DECENT one that could handle this, its not to extreme.

Multi or FSB overclocking?

What are your settings?

I have over clocked with both. 250x16 and 200x20 and have left everything else at stock as well. Still needs the said voltages to run stable.

EDIT:: Just ran another to check. Went to 250x16 and then dropped HT/NB/RAM back down to stock speeds. Set the Vcore to 1.47v and booted into windows, but it locked up Prime95.
