CPU/Mobo insane CPU temperature
- Thread starter anibhatt

It is safe to run the CPU undervolted, but do run a OCCT stability test for atleast 2 hours to make sure that the CPU can run at the low voltage.anibhatt said:Well today i decided to give the reseating another chance and also decided to undervolt the processor to 1.1 V [as experimented by someone else having the same problem on Tom's Hardware forums]. It seems the mobo is overvolting the CPU, as now the cpu runs pretty stable, i reduced the foltage to 1.1V [ which shows as 1.12V-1.15V]. The normal voltage as in the vicinity of 1.32-1.37V.
This brings me to some new queries:
1. is it safe to run the CPU undervolted? or do i need to underclock it as well for the sake of stability??
2. is the mobo to blame??
thanks for all the helps guys...much appreciated. Saved me a lot of time, effort and money which I would have wasted otherwise
You can use RMClock here to force the CPU to run at a lower voltage, while keeping CnQ enabled.
Check the guide in my sig.
PS: I've been experimenting with a Windsor 5200+ (90nm, 2.6 Ghz) in my office and I got it to run stable at 1.25V @ 2.6 Ghz (stock).
I feel that the newer Brisbane 65 nm chips can go even lower.

I've gone round and round about my ma78gm (v1.0) and amd X2 5400
overheating.
I've replaced the mobo once, and still get the issue. Now I can run the
cpu at 7x or 8x (around 1.5Ghz - cpu is rated at 2.8Ghz, or 14x multiplier)
with things like Einstein@Home, Folding@Home, Apache and JBoss running,
nothing else. Any graphics game pushes it to the warning (over 70degC)
within about 15 minutes (I turn off Einstein and Folding when running games).
I've decided to RMA the processor as well; the stock AMD hs/fan is the
basic aluminum one; no heat pipes. I've also ordered a Zalman 9500 AM2,
since the HS mount bracket has the plastic flanges and the Zalman AM2 has
a bracket that fits the flanges (I hope - the 9500 AT had a square bracket
that did not fit the mobo - the stock cooler bracket is rectangular, not
square).
Even if the stock HS/fan is not the issue, maybe I can use the Zalman to
overclock it.
Anyway, I'll report the results here. Sounds like more than a few people
are having overheating issues with this mobo.
