View Full Version : Is my motherboard holding OC back?

02-08-08, 10:16 PM
Hey everyone! Over the past few days i've been muking with my new 8600GT on this crappy old dell dimension 8400. But basically i've set my fan to 76%, Core clock to 800 mhz, and memory clock to 1000 mhz. It runs for awhile, but when I run 3Dmark06 it crashes everytime. Obviously the motherboard is a dell proprietary POS. But im seeing very little OC ability.. Anything else I can possibly do to STOP this $#%t

I never had much luck in upgraded any Dell computer.How is the power supply .Does it put out at least 22amps on the 12v rail.the 8600GT reviews I have seen says the card needs at a minium of 22amps ,and from what I can tell the card comes clocked at around 540mhz on the core and 1400mhz on the memory,and if you are running the 8600GT core at 800mhz it may be drawing more the minium of 22amps.It could be you have your card overclocked to high causeing the crashes.

Core from 540Mhz to 800Mhz?!?! lol.... no wonder its crashing.

The stock core is 540 mhz and mem is 700mhz.
You are trying to run it at 800 and 1000?

Ever occur to you that a 300mhz overclock might too much?
Only thing holding back that overclock is a nuclear reactor and some liquid nitrogen.

1. Your vga card probably gets too hot. However, even w/ good cooling, that oc might be a tad bit much.
2. There's probably a pos psu in that pos dell, which causes further stability problems.

Har Har yeah for sure. I kept it stable for around 4 hours then I got in return the blue screen of death. But hey a 3DMark06 score of 4733 for a P.O.S computer. NOT BAD?!? (nana2) Well i'll check the amps on the rails later. Thanks
