OC'ing 2600K

post #1 of 13
Thread Starter 
Well, I'm finally looking at OC'ing my 2600K. I've got a Zalman CNPS9700 cooler which keeps the idle temp to about ~32C all around, and it never peaked above 70C when running prime 95 for about an hour.

The BIOS of my motherboard is a bit different than what I'm used to, but I've already got my memory up to speed.

So what's the highest I can safely crank this baby up to?

The quick and easy answer is multiplier=45 vcore =1.4125 and you should be stable (I know 5 people first hand with these settings, stable, first try), easily. Keep an eye on your VREG temps (or whatever your mobo may call it) under full load. Most 12/16 phase MOSFETs don't have big heat sinks on the voltage regulator and they can build up some heat under heavy loads.

Notably you may need more/less voltage to run at 4.5GHz, but those are quick+dirty settings.

I would say ~1.45V as a safe max for a long term OC, just be sure to keep an eye on your VREG temps. That'll be the real limiter under load when going for a high OC. ASUS VREGs are rated to 100C (rule of thumb is under 90C), the CPU is good to over 100C (rule of thumb is under 90C for longer life).

i know that most 2600k's overclock to MINIMUM 4.4GHz without pushing it too hard

but i dont think air cooling would be enough 4 that

Would it be beneficial for me to disable hyperthreading at this point?

Why would you want to do that? HT is beneficial if you use it and because you got it, doesn't make sense to turn if off. that would essentially be like burning $100 for no reason. I say get a moderate overclock with HT (4.5/4.6) and call it a day

Makes sense
I will be doing video editing and rendering in the near future again.
I'll see what I can manage later when I get home

Munaim1 helped me get mine up to 5Ghz recently, haha.

You'll need HT for rendering, that's the whole point of getting the 2600K.

Hmm, I'm having a problem now. I clocked up my memory to 2133mhz, which is what is the speed it's rated for, and now when I attempt power up my computer, it shuts off, then immediately restarts. If I change the frequency to auto, it resets back to 1600 and it boots fine.

Make sure you bump the VCCIO to around 1.150v when using that amount of RAM and that speed. It should help overall stability. Run the RAM at stock voltage, stock timings and stock frequency with a slight VCCIO increase, then you can concentrate on the CPU overclock.

XMP was disabled. I enabled it, it set the frequency to 2133mhz, and I've done several shut downs and it stopped shutting off, then turning back on. So I think that's solved now.
