[Mr Meltdown]

H'mm, I've just had a few "moments" with my IS7.

When bench testing my CPU in the IS7 I had it posting @ 290FSB and running Windows @ 285FSB. However when I moved it into my PC I can't get over 273FSB (275FSB just locks at POST). This could be due to a different PSU though or loading on the motherboard or some other reason..... But here's what I just decided to try.

I decided to take the north bridge cooler off, clean off the TIM goop that was on there and put AS3 on it instead. I used alchohol to clean the NB and the heatsink as well and then applied a THIN smear of AS3 to the NB core and refitted the heatsink / fan back on it.

Now the mounting method for these just plain old sucks, there's just too much movement available within the mounting setup to allow for a bad fit.

I rebooted and got the siren, so I rest CMOS and chose 250FSB....... but I still got the siren. I reset CMOS again and also removed the NB HSF and refitted again trying damndest sure it was as true as I could get it. OK things are as they were before, but no better...I'm still unable to get past POST screen with 275FSB. (I'll swap PSUs later or unplug everything off the mobo and see if either of those help)

So what does this little escapade tell me? That NB HSF mounting must be involved in max FSB ability of these motherboards. If it's a bad fit from the factory your max FSB will suffer.

Suggestions for an NB replacement and mounting method anyone?

Back to the drawing board.....(and yes my sig is a lie, i'm @ 273FSB)

Cheers,

MM
