i7 Overclocking for Beginners

Is there a program to see what my ram's set at? I can't see to find the RAM multiplier, though I do have an option to set RAM frequency, there is a 1604 option there. Should I set that?

Sorry for all the questions but as my board isn't the one in the guide it's a bit confusing for me.

I'm currently at 3.2 btw with domino on middle mode (adjusts fan as it needs to), turbo boost is still on though so it's moving it up to 3.4 a lot on OCCT. 20 mins into an OCCT test and max temp recorded is 68 degree's on coretemp.

Turned turbo boost off and max cpu temp atm is 72 degree's with the domino on low speed. I set the ram to 1604 as I said above at 1.65v, cpu v is 1.2.

Temp drops down to low 60's max at 3.2 with domino on middle settings.

I also tried at 3g and max is 58 degree's.

Sorry for the late reply. CPU-Z should be able to help you with RAM timings to check them. You'll want to turn Tubroboost off because it can cause stability problems at high overclocks. Those temps look fine, you don't want to exceed 80, but if you're below 70 that's even better.

RAM timings on the P6T? Hmm. I have a friend who has a P6T who may be able to shed some light on this, I'll get some info off him later, unless someone else wants to interject?

Thanks, had any news on this yet? Want to make sure my settings are right.

Okay. Got it. Row to Row Delay, or tRRD, is not the command rate, as far as I can tell.

rsmarsha. I aplogise that I have been so busy as to help you directly and quickly with this.

Anyways, tRRD or to Row to Row Delay is not the command rate, and I recommend you reset that to default/auto.

In the P6T BIOS the Command Rate option is called DRAM Timing Mode (under AI Tweaker--> DRAM Timing Control). I had to ask my friend cmndr_andi to have a look at his BIOS because he has a P6T Deluxe V2.

The RAM timings, normally listed in the form X-X-X-XX are tCAS, tRCD, tRP, tRAS respectively.

The memory controler for the i7 is capable of handling 1T command rate, but 2T tends to be way more stable.

Thanks, I'll adjust that tonight.

You don't have to apologise, the fact your willing to answer my questions at all is great.

If I could work out how to give thanks to a post here I would do.

I also couldn't find the multiplier for the RAM instead there was a setting to set the actual RAM speed, I'm assuming that the setting in question actually changes the multiplier depending on what you set the RAM speed to. I set it to 1604, I can't remember the name of the setting I'll have a look tonight and post it here.

I need to install CPU-Z to check the RAM and will do so after I set the above settings correctly. I believe CPU-Z will show me the command rate so I can verify it's working.

Ok here is my CPU-Z output.

I'm a bit concerned about the frequency, I have 1600 ram and in the mobo settings is set to 1604.





Shouldn't the 749 be 1600?

Also in the CPU tab what does QPI link mean? It's at 3598.

It's fine. The freq reported by CPU-Z is half the actual (the hint is in the name, DOUBLE DATA RATE). Your QPI is also fine, it's just the current freq of the link. It goes up under load conditions.

Ah thanks, so I shouldn't be trying for 800?
