Looking for ASUS p6t deluxe v2 screen shoots to match OC guide

If you have memory with XMP profiles, choose this setting for AI Overclock Tuner, if not, set it to Manual, and you will get the option to enter the BCLCK Frequency.

Ok, I'm still lost. I'm trying to get to 3.6 on the i7 920.
1. What is the CPU voltage default to start it shows AUTO but I need to put in a number?

2. Same thing on the PLL voltage?

3. Which one do I need you adjust when I change the BLCK Frequency 172?

4. I changed the DRAM frequency close to its original setting at 1379 and loosened the timings for 7cas to 8cas. I'm using OCZ LV 1333 777@1.65. I have the voltage set at 1.64375.

Also which of the voltages do I need to keep within .5 of the QPI/DRAM Voltage?

VCore = what in the ASUS bios?

Auto lets the BIOS control the voltage, and will let you overclock some without having to set a specific voltage yourself. Default is 1.2V.


Default is 1.8V.


That would depend on your CPU, motherboard and cooling, in other words, you have to try and see what makes your system stable.


Ok?

..


From the linked overclocking guide: QPI/DRAM Core Voltage must be within 0.5V of the DRAM Bus Voltage. This could only be an issue when the DRAM Bus Voltage is set very high (1.71V-2.46V).

..


That would be CPU Voltage.

BIOS settings set at:

i7 920 running at 3612 MHz

AI Overclock Tuner set to Manual

everything else is set to Auto except the following

BCLK 172
CPU voltage 1.21250
Dram voltage 1.64
Memory freq. 1379 w/loosened cas timing to 8-8-8-24.

Temp is at 70 max at full load. Idle 38

Should I try lowering the CPU voltage to the stock setting at 1.2 or just leave it?
Any other suggestions?

The less voltage you use, the cooler the CPU will run, so yes, if this is the overclock you want to run 24/7 (which might be a good idea to not go higher considering your temps), now is the time to fine tune it by seeing if you can lower any voltage settings, and tightening memory latencies.

Built for gaming: Call of Duty WAW, and Bf: Bc2. I don't think these games will push it that much do you?

Video card EVGA 275 GTX

Only going to 1.21250 on the CPU voltage is pretty low isn't it?

Would lowering the memory below the voltage stamped on the memory help the temps or is it a bad idea?

You mean above the temps you had using Prime95 (or whatever you have used to stress test?), no, if you keep that overclock you will be fine running all other applications.

Yes, you have a low voltage, but you are also at the sweet point, pushing it further would start to require (or generally do so) much more voltage, as an example, I am running mine at 4 GHz @ 1.3V.

Lowering memory voltages would not help cool the CPU.

I want to keep it a 3.6, so should I try to lower the voltage or just leave them alone because they are already low enough?

P.S. I left the PPL or something voltage this is under the CPU voltage in the bios on AUTO. Should I put in a voltage on that one?

I'm using prime95 for the testing. Should I also run memtest?

The settings you have right now are more than fine if your system is stable.

You could set PPL to 1.8 and see if the system is stable, if not, up it one step and test again .. you know the procedure.

It is always advisable to run Memtest86+ when building a new PC (getting new memory sticks).

Update, put PPL at 1.8.
Ran prime95 for an additional 4.5 hours on the blend test.
Ran small FFTs while playing Call of duty World at War online it worked great.

Max temp only hit 72, most of the time it was around 68.

Idle 41

Temp hits 57 while playing COD only w/no stress test going. Is that a good temp for that?

The 275 GTX GPU temp gets up to 70, hows that?

OC is holding at 3.6 w/no problems.

Thanks a bunch for the help!
