having to underclock for stability

[cygnet]

Hi all,

I have the following system:

1.33 ghz Thunderbird, AYHJA (266)
GlobalWin Copper HSF (CAK28) w/ Arctic Silver
256 meg DIMM, PC2100
Lian Li PC67, stock version

My temperatures are mid twenties C (room), 33 (board) and 49 (CPU, web surfing).

Everything's seated well, but the CPU still seems a bit hot. The bigger problem is that I'm having to underclock (120x10) just to run stable (i.e. no blue screens). Any ideas? I don't know what else to mention that might be relevant.

(EDIT: the PSU is an Enermax 430W and mobo is Epox 8HKA).

what is your core voltage at?

[cygnet]

1.8 at the moment. I've tried everything from 1.725 to 1.85.

hmm. you said idle is mid 20's and full load is around 50's? sounds like the heatsink might not be on correctly.

[cygnet]

nah, it's 50 idle, maybe 53 or 54 loaded.

Y'know what? I'm killing myself here and I'll never ever be takjen seriously in the forum again, but...

I hadn't realised that the clip on the HSF was angled off-center for a reason. The clip wasn't pushing down on the die.

hmm. well, it could be overheating. if there is somthing up with the probe, i.e. it not totally touching the cpu, then it could really be hotter than that and become unstable. How about ram settings? after I switched to win2k, it didn't like the higher bus speeds for the RAM.

well, there ya go. :)
