Abit uGuru Reliability

[Lukozer]

When i first booted my AX8 system (see link in my sig for full specs), i was quite stunned to see my idle temps at 23c (identical to room temp) and load temps at 45c. Since a brief power outage though, my system is now displaying much higher temps. 47-51c idle and around 62-69c under load.

First question... which set of readings is the more accurate?
Second question... Why is there such a huge descrepency between the two readings? Is this purely down to uGuru? I am taking all my measurements through the Guru Clock since while i have this connected, i cannot get the temp readings in the BIOS!!

Another thing is the temps barely change when overclocking. Using the uGuru overclocking utility i overclocked slightly to 2730mhz and idle temps remined pretty much unchanged, still around 51c idle, although under load i was approaching 74c, which is only 1 degree below the temp that sets off the warning alarm. These temps are taken using the stock FX-55 HSF incidentally.

I am now back to running at 200FSB (the default FSB on the AX8 is actually 204, but i decided not to take any chances with a CPU as expensive as this one) and the CPU is back to running at exactly 2600mhz, with 47c idle temps (still showing as 47c while i type this).
Do i have good reason to be concerned, or is it that the initial temps i was getting were the incorrect one and the temps i am getting now actually right?

47c sounds a lot more accurate than 23c. Cause to get int he 20s idle youd have to have a)water b)a pretty chilly room

My winchestor never got below 26c and its running 400mhz slower and on 90nm.

Mine starts out at room temp (23 to 25C). Average without cool n quiet is 35C (250 MHz FSB with 9x multiplier or 2250 MHz for Winchester 3000). Maximum load is 49C. With cool n quiet running (250 MHz x 5 multiplier or 1250 MHz), it's 25C.

Micro Guru readings basically mirror the BIOS readings.

I would remove and reload Micro Guru. Also check reported temp in BIOS. I would say your 1st reading is more accurate. Perhaps data corruption in Windows? If you see similar high temp in BIOS, then perhaps the heatsink has worked lose. Clean up the thermal paste and reapply. Make sure the CPU cooler is fully seated.

Also reset the CMOS.

I've uninstalled and reinstalled Micro Guru twice, still the same readings. For some ridiculous reason, the AX8 BIOS does not report any temps!! I don't know if this is because i have the Guru Clock fitted or if this is some king-sized cock up by the AX8 BIOS creators. The heatsink is fitted perfectly, so nothing has happened there.

Maybe that's how microGuru works? You see the temp in the clock and not in the bios when installed?

Yeah, i figured that much out... My question is how reliable is it, since in the space of one reboot my temperature readings are now around 20-30 celsius higher than they were before...

i'd say your actual temps are probably somewhere in the middle of the two.. if you're gettong over 70C at load (too high), then either the reading is waay off, or the heatsink needs to be reseated.

given your ambient room temp being so low.. i'd reaseat the heatsink just in case, and if you dont see a change, the readings are probably screwed.. i wouldn't want to be running >70C

You should be able to view the temps in BIOS. Not sure if you're brave enough to re-flash the BIOS. Also reset CMOS and perhaps clean install Windows.

Don't forget that the system was "okay" prior to the power outage.
