i7 950 D0 OC on WC

Hi all,

I'm trying to hit 4.6ghz on my i7 950 (see specs in sig). What would be a safe max vCore for this CPU? I've currently got 1.40 as my vCore (showing as 1.392 in cpu-z), QPI/DRAM at 1.40 and DRAM Bus at 1.68 and get BSOD during boot up before it reaches the logon screen in Win7.

If I drop the multi to 21 I can boot straight in and running IntelBurnTest at Max on all threads gives me temps between 65-70 in Core Temp. 1.40v vCore seems a bit high to me but imo the temps seem fine, would it be a bad idea to run it that high for daily use?

Thanks!

Edit: Decided to just stick to 4.4-4.5 as 4.6 needs way too much voltage to be stable so not worth it

Ran mine @ 1.5v under water no problem for ages

There isn't a hard and fast rule about how much voltage to put through a CPU. If you imagine that the CPU has a life of, say, 10 years and you shorten that life to even 5 years, do you care?

Most folks on here swap their kit out fairly regularly. At the height of my obsession I was buying a motherboard and CPU every month or so, but now I change annually unless something truly amazing comes out, so putting 1.5V through my CPU to get 4.5gHz out of it still gives anyone I sell that CPU to at least another year of use.

If your temperatures are fine, go for it. And even if they're not the CPU will throttle to protect itself at which point you have to back off for performance sakes anyway.

Thanks. I upped the vcore to 1.44 and no luck so thought what's the point of such a huge volt increase for negligent difference. I'm gonna try for highest BCLK and OC the RAM while using 20/21 multiplier instead of 22 to get around 4.2-4.4ghz instead.

And yeah even with vcore over 1.42 on my WC loop the temps hit about 74 on core0 and 70/71 on the rest. Would love to see how my WC loop performs on SB, I could probably push the clocks it a fair bit on a decent chip
