Hello, guys, here is my problem.

i oced my 3770k to 4.5GHz with H100 cooling. everything seems fine beside my thread number on CPUz is only4. i thought 3770k should be 8 thread, so what's wrong here?

edit, i am using asus z77 v-pro MB. and corsair 1600 ram.

perhaps update bios or reset cmos? and check in the bios for hyperthreading etc

You need to enable HT to get the other threads. That's what HT is.

As to how that effects your OC, I'm not sure.

If you disabled HT, that's the problem! Hyperthreading is what turns your 4 core CPU into an 8 thread one.

Overclocking and hyperthreading are completely separate things. Hyperthreading gives a performance boost in some circumstances but not in others. That's true whether you've overclocked or not.

...nothing like follow an OC guide, disable HT without even knowing what is it....

FYI HT might make your overclock unstable; that's why most overclocking guides have you disable it, and i would leave it off myself - no real use for HT on anything but synthetic benches, as games / apps don't use it (well.. a few do .. but if you use these, you'd know)

If this commentary were for me:
I do know that HT might get OC unstable. My main complain is with people that blindly follows a guide, clicking in whatever the guide says without knowing what he's doing. Like the case here, OP disabled HT without understanding that this is feature that enables 2 threads/core.

If this commentary weren't for me:
Yes, I do agree with you. But let's not forget the new rockstar game. Max Payne 3. It recommends a holy christ Intel i7 hexacore with hyperthreading activated!

You'll get higher performance with 4 threads at 4.5Ghz than with 8 threads at 3.5Ghz (3.9Ghz turbo).

Could you go higher than 4.5 on it with the H100? Just curious...
