i7-920 watercooled overclock help

JordanNaylor · April 18, 2013

Hi guys, looking for some help overclocking my i7-920. Old I know. Recently did a system upgrade mostly with cooling in mind, so I bough a coolermaster Haf X and new fans to fill every slot.

I'v got an 850Watt hybrid-modular PSU, 2GTX 670's and 16GB DDR3 1333 memory too.

Motherboard is very common, Asus P6TD v2

So, my CPU cooler is a H70 in a push-pull configuaration with some silverstone high performance quiet fans, idles in the low 40*C's and hits 75*C tops in 3Dmark in Fire Strike.

Current overclock is 4.25Ghz, but I seem to have hit a "barrier" of sorts. Any higher than this and I start getting blue screens. Temps are barely higher, but it blue screens. I don't want to push excessive voltage through either. I don't know if its the RAM holding it back, or im just not daring to push as much voltage as it can handle.

Ideally i'd like 4.6GHz maybe more. Is it even possible with the 45nm architecture?

Cheers

Jordan

75C in 3DM? You're done overclocking.

Your temps are too high to let you go any further. More volts=more heat and more heat=more volts too, so it's an up hill battle unless you freeze your board.

Congrats on the overclock. Don't go and buy an H220 just to get an extra 100MHz, put that monies in the new platform jar :D

Isn't the max temp like around 90 or 95 for that chip? I may be mistaken, but he should be able to push it a little further; granted, you wouldn't want it anything above 85, but it's not completely out of the question. That said, 4.6 is perhaps looking too much for that chip - 4.2 is good as it is, and as Wats said, any more and you will risk damaging your chip simply due to the much higher voltage required.
