New to i7-2600K and Intel in general - Overclock?

post #1 of 5
Thread Starter 
So today I decided to upgrade my computer to an Intel Core i7-2600K with the Asus P8Z68-V PRO motherboard. I also ordered 8GB (2x4GB) of Corsair Vengeance DDR3-1600MHz C9 RAM.

Naturally, this must be overclocked!
I read a while back that the way to overclock Sandy Bridge CPUs is to use the CPU Multiplier, quite simply. I'm perfectly happy with this but I have some quick questions:

1. What is the maximum CPU voltage I should be setting?
2. What are deemed safe temperatures under 100% load?
3. Does enabling/disabling HyperThreading affect maximum overclock (I want to keep it enabled)?

Thank you for any guidance you can provide!
For reference, my cooling system is basically a custom watercooling loop for my CPU and graphics card (new card will be a GeForce GTX 570). The CPU waterblock is an EK Supreme HF Full Copper and my radiator is an XSPC RX360 with six 120mm fans on it.

1. 1.5ish with watercooling.
2. 72c/ 80c
3. enabled generates more heat.

Of coarse, these are general specs.

1) 1.52v
2)72c (as per intel)however..it'll survive higher..i wouldn't push the envelope too far,though
3)hyper-threading adds heat

You're water cooling, so heat won't be a huge issue.

I wouldn't go much above 1.5 volts

I stay under 85 in linx/80 in prime (remember, your cpu will never be that hot in real world usage anyway)

Hyper-threading adds heat, but it's still worth it.

Thanks very much guys!
+rep to all!

I will try to stay below 1.50V then although I'd happily adhere to "air cooling limits" as opposed to "watercooling limits", for extra safety margin. 72° or so maximum sounds like a good safety margin, too. HyperThreading will indeed stay enabled. I want it for 3ds Max!
