VCore Alternating

post #1 of 6
Thread Starter 
New to overclocking here.

I'm currently running stability tests on my 1090T @ 3.8Ghz to ensure that everything is running fine before bumping up to 4.0Ghz.

While running prime 95, once my temp is reaching 57 degrees and staying for a few minutes, the Vcore drops from 1.45 to 1.32 and the Core Speed from 3.8 to .955 Ghz. I'm not getting any errors from Prime95.

I'm not entirely sure what's going on. Does anyone have any information about this?

In the meantime, I've set everything back to stock values.

Thank you,

Sciezka

Check to see if Core Boost (C1E) and Cool N' Quiet (CNQ) are off in the BIOS, as they are known to change the processor clocks and voltages.

did you set the core voltage in bios?

looks like c1e and cool&quiet are enabled, they will scale back core voltage/cpu multi when idle


57c is pretty warm, 62c is the max, try to get it closer to 50c

set the core voltage lower or bring down the overclock

I had both disabled, but these shouldn't have done anything as this was under full load in Prime95. Voltages were set in BIOS, not through Overdrive.

Quite honestly I'm at a loss as for what to do about the temperatures. I thought that with the H50, it would be lower than what it's at. With stock settings I'm idling at 34, full load 45ish.

I haven't done changed anything around anything after assembly of this PC; everything is how I installed it. Thermal paste on the H50 is stock.

Perhaps I just got unlucky and got an unusually hot 1090T.

Try push/pull with the fans on your H50, I was very impressed when I got my H70 and the temperatures under load and at idle droppped dramatically.

go to start<-- in windows then go to the box at the bottom, type in power options
change it to high performance=problem solved
