OK guys I'm still playing around with the settings in the BIOS, but this is what I've got so far:

http://valid.canardpc.com/show_oc.php?id=489296

My concern at the moment is the RAM timings. They look a bit stuffed, should I do something about it? Sorry if I seem a bit ignorant, I'm completely new at this.

Edit: Also, this probably isn't the right thread but is it possible to overclock my graphics card? Will I get a significant increase in performance? Thanks.

EDIT: here are some pics of the chip with the IHS removed, as you see it doesn't have any resisters inside it like AMD chips, they're all on the bottom. I used the blades from a disposable shaving razor, whatever you use it helps for them to be very thin. normal cutting razors are difficult to get in the crack between the IHS and PCB
Thanks for you comments but it's already off ! I applied some new tim and reinstalled the IHS (not glued),my scythe mugen hits a few caps when install without the IHS and the 1283 has only 1 heatpipe in direct contact.

Still a nice improvement, Ran 8 hours Prime 95 small FFT's 304x12.5 1.37V ( load) Vtt 1.3V, temps around 57°c. IBT around 63°C. With the stock tim between IHS and core prime temps where 70°c and IBT 80°c.

It seems the crappy zalman paste (not the new silver, just plain white) i had to use has a cure-in time, temps lowered by 8-9°c after running prime. Or maybe it's the AS ceramique i used between the IHS and Core.

i have the same motherboard as you you can't go for 3.3Ghz but you can go for 3.27Ghz which i managed to get stable.

i just posted this somewhere else, i figured it's appropriate here

"performance wise it's best to max out BOTH your FSB and your CPU. the thing is when testing your cpu, keep your FSB as low as possible to get the clocks your looking for. later on once you find a high stable setting then up the FSB and lower the multi to max out both the cpu and fsb. when you clock your FSB high you're basically overclocking TWO things at once, the FSB(part of your motherboard) and the CPU. So it's best to test them independantly. if I want to find out if my system can do 400 FSB I can set it to 400 FSB and lower the CPU Multi so that the CPU is running in spec. if the system is stable it tells me my motherboard can do 400 fsb. When TESTING you want to make sure you're only overclocking ONE thing at a time, but when you've found the high clocks for each component, combine them in the most effective way.

i have my e5200 at 3.75 now and I can do it with 300FSB*12.5multi or 326FSB * 11.5multi, the latter is better because they're both the same CPU clock speed but the FSB is also higher. FSB effects memory performance(read/write) you'll notice the effects of high FSB most in memory benchmarks like Everest

Just got this cheapo...

VERY impressed with it so far.

Currently stable on 250 x 12.5 (3.125ghz) AUTO volts seem to be sitting on 1.31v

Had it stable on 280 x 12.5 (3.5ghz) 1.26v

But motherboard seems to be playing up...when I change multi to 10.5 or set manual voltage (it only saved to cmos with that above setting...any help?

Gotta wait 2 weeks to buy aftermarket cooler (lost the adapter for the old Zalman). Once I get that and this motherboard issue sorted I'll be posting real results.

Update:

I just booted up with 375 FSB with 10.5 multi at 3.93Ghz. I'm gonna see if it's stable.

Modified my Scythe Infinity today, it fits my P5K-E + lidless CPU perfect now, bolted down with screw+ spring and a steel backplate !

333X10 1.19V (load)
Prime 1H stable ~ 41°c
Linpack 1H stable ~ 51°c

I'm pleased with these results

Ran some other settings :

351X11 3861mhz 1.4V
Linpack + prime max stress 74°c
only prime 61°c

Could be lower, but still pleased with it.


Edit : Just placed a second fan on my Infinity and it dropped my Linpack temps to 44°c using linpack ! ( 333X10 1.19V).
