Before WC = 3 GHz after = no OC? - Page 3

post #21 of 36
keiko, he replaced the stock heatsink on the northbridge w/ an aftermarket one, so if the aftermarket one isn't doing a good job for whatever reason, that could be it.

Another thing the OP could try is getting a water block for his northbridge.

can you OC at all, even 1fsb, also can you up the NB a little

Try a very small overclock. See what happens.

Maybe you damaged a capacitor when you were installing the WC.
Only about 213 lbs of force, which wouldn't be that hard to create using your typical threaded rod and nut arrangement. This is why so many watercooling kits come with the springs. It looks as though he is using springs, and they look like they are not fully compressed...so my idea is wrong anyways

Could it be the power supply failing? Or overloading? It seams that a Quad Core, 8800 GTX, the RAID'ed drives plus the added Water Pump might be alot for the PS to handle. May be wrong but, it would make sense.

Try the swap back to the air and see if wont oc then could have messed up something installing,also if you install the nb cooler wrong temps would be high but would mess up at stock too? maybe the power supply whats the rails rated?

You never know.

Another thing, doesn't look like you have room for it, but could you turn the northbridge heatsink the other way? Heatpipes don't work if they're perfectly flat or at a downward incline, and I'd say there's a slight downward incline here (since the weight will pull it down a bit).

If you can turn it the other way (by putting that gfx card in a different slot), then the heat pipes will function as intended.
Well i took that 80 mm fan off of it to make sure it was contacting correctly and put a 120 mm fan blowing on it but not leaning on it.

there aren't any northbridge temps that i can find anywhere, there's a cpu temp, mobo temp (just on the pcb from what i can tell by the temps), and a temp for each core.

Have you disabled all the useless things in bios?
yeah i actually saved the settings using the nice little tool in the bios so i know these are exactly the same settings.

I actually got it to overclock but i had to use the asus AI overclock thing which isn't very good. then after that it overclocks by hand fine but i can't get it to post over 2.8 now...

i thought about that so i mooved all my cooling to another power supply, and unhooked any unneeded hdds.

i think this might have something to do with those northbridge strap things i read about here the other day... so should i try dropping my multi and upping the fsb?

another wild stab in the dark..

are your RAM settings the same as before? Voltage/MHz/Divider/Timings ?

yup those got saved also, but i like to keep them at stock because i don't see a performance gain when i overclock them... so i set the voltage manually to 2.1 (rated) and then set the sli ready option to expert, and then unlink the fsb and memory (an automatic divider setting which keeps the memory at stock).

I'd try your old BT first, and then see if there still is a problem. If so, I'd then try another motherboard, because, as someone else mentioned, you might have broken a capacitor.
