Quick LGA775 question...

Sumanji · 17 Sep 2008 at 11:01

Hey guys,

Just installing an LGA75 chip for the first time - I've put the CPU in the socket and it sits flush, but when I close the lid, it doesn't go all the way down. Seems like it needs a lot of force to get the locking mechanism in place again... is this normal??

Feels like I might crush some pins :eek:

Cheers,

Suman

Thats normal, mine takes some force (though nothing excessive)

Certainly doesn't compare with my old A8N32SLI board, trying to put the stock CPU cooler on that with the locking pins made me think it was going to snap the socket straight off the board!

They do indeed sometimes take a little bit of effort....Not so much that your hand is straining obviously.

As long as you have the noches lines up with the cpu, and the lid goes down first while the 'arm' is open...Then you should be fine.

Ok cool, thanks guys...

2nd question! I'm installing a Silverstone NT06 cooler... just mounted the backplate which goes on the rear of the mobo and it causes pretty major flex of the PCB :eek:

I haven't even tightened the screws that much! Should I leave them loose until I mount the HSF and tighten those screws? I guess they will oppose each other and the mobo will not be as bent...

Well....the standard LGA fan that comes with intels makes hte board bend a fair amount...

You could tighten them lightly, so its only finger tight via screwdriver, instead of tweaking it at the end to 'tighten' it. See how that goes?

I've never installed them, so I can't say for sure. But a little bend is nothing to worry about.

Hmm I could try mounting the backplate turned 90 degrees, but this would require me to trim some rather large solder stubs sticking out of the back of the board. What could I use to do this?

Cheers,

where's that thread gone where the guy got his dad to hit a mobo with a hammer to get his QX to fit?... lol

I wouldn't if I were you. You shouldn't need to take any such drastic measures to fit a CPU cooler and you risk damaging your mobo. As said above, a little flex in the PCB is acceptable.
