Okay, so I wanted to overclock my system to around 3.6 maybe higher on stock cooling.

Here are the specs:

CPU: Q9550 @ 2.83GHz
Mobo: XFX780i
VideoCard: GTX260 Superclocked
PSU: 750W Corsair
Memory: CORSAIR XMS2 DHX 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X4096-6400C4DHX
Windows 7 64bit

I just tweaked the FSB up to 1500 and the CPU Core to 1.2

Ran Intel Burn with stress level on standard and times to run at 5. passed

Recommendations? Would like to reach 3.6 if possible. right now its at 3.19

Everything is basically default except for the ones I said I changed above. Also, I get a floppy error when I boot for some reason and I have no floppy at all.

I would like to overclock the CPU, RAM, and Video Card to be stable with stock cooling if possible.

Actually error is this: Floppy disk(s) fail (80)

Have to press F1 to bypass

Still get error even after I turned off OnBoard FDC Controller

What should i run to test the system stability?

Check for RAM stability using Memtest86+ prior to attempting to boot into Windows, and for system stability use a program like Prime, LinX, Linpack, etc. in Windows.

Click the 'All' button in order to utilize all available RAM, which in turn will maximize the Problem Size accordingly. Leave the Run times at the default of 20, and make sure to monitor the core temp's while LinX is running.

Ok, how hot should the system get? Or will it stop if it gets too hot?

I am at 46% on the memory test now. Gonna be awhile more before its done.

Okay, after only 1minute and 26seconds into LinX test using all of my memory, which was around 7GBs, the temperature reached a high of 85 Celsius.

How big of a difference can having to much thermal paste on the CPU make? I fairly sure I put way too much.

I got a Antec Nine Hundred Two case with 5 fans in it. My room is fairly hot because of the PC, like at least 10-15 degrees hotter then the rest of the house. Right now the temp is at 50 Celsius at idle basically.

Edit: I passed the memtest with 0 errors.

A TCase of 50C at idle is way too high, and > 85C under load is also too high. Try reapplying the thermal paste, and when reseating the HSF make sure it's evenly seated and as square to the socket as possible. Your best bet though would be to invest in a better cooler.

Okay, before overclock Idle was around 32 or 38 Celsius.(not sure)

What aftermarket cooler do you recommend?

EDIT: how big of a temp difference do you anticipate re-applying thermal paste will make?

EDIT2: System won't even pass with everything back to normal. 3minutes in temps reach 80 Celsius.

Okay, I reverted everything back to normal factory settings and passed the LinX test. Here is a screenshot:

With a 45nm quad running at only 1.152 Vcore, core temp's (Tjunction) of > 70C and Tcase of 76C under load are way too high. You need to get yourself a better HSF.

I have the stock fan, shouldn't that keep the temps under those? I mean don't they run these same kind of tests?

Okay last night I went out and picked up some aftermarket cooling. I picked up the Cosair H50(I know I am going to catch some flak for this but oh well).

I tested again on the stock CPU settings and the highest temps reached was 45 Celsius under load. It now idles around 29-30 Celsius.

Now would you recommend I try the overclock again?
