CPU voltage question

siclilmonkey · 20 Jul 2008 at 19:10

Iv just set up my new Asus P5Q with E7200 and im slightly confused with the voltages.

in the bios i set the voltage to 1.35 but in cpuz it is saying the voltage is 1.088 and pc probe says the voltage is 1.09

temps are about 56c with dual prime @ 2.8ghz

hummm well pc probe is just rounding the value up.... but that is very low, when cpuz says 1.088, is that at load or just idle, because u might have speed step enabled so when not doing anything it might crank the voltage right down and only bump it up when under load. so i would check that first.

it was at full load. think iv solved it now

other problem i have is temps at 1.088v im at 55c on the cores

iv tried resetting the hsf no luck will have to try again tomorrow

hsf - TRUE with 120mm 1600rpm fan + Arctic Ceramique

its a coolermaster stacker case with
2x 120mm front intake
1x 80mm top intake
1x 120 rear exhaust

iv spent 2 days on new pc been hard work

temps at load at stock?

Sasso · 20 Jul 2008 at 21:48

humm thats odd because i have the same HSF and mine at loads goes to about 50 oC with a 1.36 voltage in cpuz..... humm tricky, anyone else got ideas?

stock voltage but 3ghz clock

iv done a quick test to see what the temps were at 1.35 and they were 75c+

going to try reset the hsf again

after resting the hsf again the temps are exactly the same

edit////

i have set cpu voltage to 1.35 again and cpuz and pc probe are telling me the voltage is 1.12.

i don't understand

speed step is disabled in the bios but it is still reducing the multiplier according to cpuz

im thinking there is something up with the board :S unless i am missing something??

Have you updated the BIOS yet?

What thermal paste did you use?

siclilmonkey · 21 Jul 2008 at 17:21

i havent updated the bios

i used Arctic Ceramique same as AS5 without the silver

edit//

speed step now disabled but voltages way way out

I would update the BIOS. The readings may have been corrected in a newer BIOS.

And do it via the flashing option within the BIOS, and not via the Windows flashing utility.

iv flashed to 0703 easy

right with the voltage you have to type in the numbers using the keypad where i was using the + and - buttons

was just reading on the ASUS forums that the beta 0901 bios recalibrates the cpu temp diodes and there's a 10c drop in temp. dunno whether should try that bios
