i purchaced the ultima oc 8800gt system and the system has been quite unstable, i've just discovered the psu seems to be extremely hot, when the system is being used heavily the psu runs at about 95c (hotter than the cpu and gpu), the system comes with the ocz 600w psu

does anyone know if this is normal for this model?
 
this is according to everest, although i've just put my hand around the back of the psu and the air coming out is cool

im trying to identify what the problem is with the system so if i need to send it back it can be as quick as possible as im dependant on the machine for work at the moment

i have a lot of bluescreen issues at the moment, and the errors pointed towards the memory, i ran memtest once and it reported an error but i ran the test a few more times and the error disapeared so not sure what to think about that, but i just decided to give everests stress test a try and noticed the psu readings were really high

ok heres the temps

and this is the system details, although i have
4gig instead of 2 as listed there

thanks thats good to know, so i can rule that out as a cause of the problem


@Cob, you mentioned i may be able to tweak the voltage settings to help, could you give some specific details, i don't know enough about overclocking to know what to adjust and what are the safe ranges for each setting, i would really be happy if i could get my system stable so i can continue with my work, this has been horrible timing right in the middle of a project

Ensure the DDR2 Voltage is set to 2.2v in uGuru>Voltages Control in your BIOS.

If it is then raise the CPU Core Voltage by 0.02v.
 
The CPU voltage *should* be fine at 1.45v.

Have you got 2 or 4 sticks of memory? If it's 4 then set the MCH voltage to 1.35v or thereabouts.
 
@ lazyk

I would certainly investigate the temps for the PWM1 as I am also running a Q6600, Abit IP35 Pro and my PWM1 temps in everest now is 41c

[edit] just ran the Everest stress test and my PWM1 didnt go above 55c, my Q6600 is at 3ghz just as a reference to work from, you also have a better case than me for cooling.

I know the PWMs on the Abit IX38 Quad GT run very hot but as far as I have seen the IP35 Pro runs a lot cooler in that department!

its 4 sticks,

the voltage settings are

DDR2 voltage 2.200v
1.27v MCH voltage 1.33v
ICH 1.05v voltage 1.12v
ICHIO Voltage 1.55v

so u think the mch option is a better way to go than playing
with the cpu voltage then

d.m - thanks for the reference temperatures
 
If anything I'd say the CPU voltage is a little high, but it won't be causing the blue screens.

Up the MCH voltage to the hight setting to help boost it for running 4 sticks.
 
what is the negative effect of having the cpu voltage to high, is it gonna put extra stress on the cpu, ie if upping it fixed the problem should i just be happy about it and leave it or should i definatly try other methods
 
For the meantime you might be better dropping it back to 3ghz til you finish your project. You should be able to drop the CPU voltage to ~1.4v without any issues when doing so. Remember to note down any settings that you change.
 
yes i will try and knock the settings down and hopefully this will at least allow me to finish my project, really terrible timing for all this to happen

when my system first arrived it was running at stock speeds, i had to manually follow their instructions to overclock so im starting to think the system was never checked for stability when it was built and unfortunatly im only just discovering this when i really need to use it the most, wonderfull timing, but thanks for all the tips anyway, now i just gotta hope its stable at slower speeds :(
 
I'd assumed it would have come pre-clocked.

You'd be better starting all over again when you've finished your project. There's more than enough information and helpful users on these forums to overclock a Q6600 to a stable speed.
 
yea its supposed to be preclocked, it appears the machine must have skipped a couple of stages during the building process, i'll just send it back when i am able and hopefully get a system thats been setup and tested properly
