Dram Voltage - RAM Voltage
Dram Termination - Max voltage allowed before mobo reboots computer ?
Channel A reference - ????
Channel B reference - ????

Lastly, I have no idea how the settings in the ADVANCED TIMING CONTROL can be used.. Lol sorry for such noobishness but I must learn somehow!

P.S.- Successful Overclock at 3.0 GHZ now with Vcore at 1.45 | MCH at 1.4 i think
Prime 95 ran for about 5 hours with No errors

Done

I think to keep current i am going to update my bios to the newest version tonight.

Hi all,

Please help a newbie. I just built a system: P45-UD3P, Q9300 with Freezer 7 Pro, G-SKill DDR2 800. How can I OC my system?

If I want to get something higher than 3GHz, my RAM will operate at higher freq than 800MHz. Why is not there an option of the memory multiplier small than 2?

Thanks,

D.

I have seen your chip get well over 3.0GHz, but it varies from chip to chip and board to board.

As far as the memory frequency goes, a multiplier of one wouldn't do anything and anything less than one becomes a divider (doesn't make sense, does it?). Anyway, it doesn't really matter what frequency your CPU runs at, it's more a matter of finding the right memory frequency/memory multiplier to keep your RAM stable with a higher CPU FSB. Play around with those two options and you will see what I mean.

You are right Enyalius. I did some search before OC, and I found a lot of people getting to 3.75 without any problem. And that freq multiplier does a big role in my system. Unfortunately I can adjust it from 2 and bigger, so if I set FSB too big (for example, 450 to get 3.375 GHz, then memory runs at 900 if multiplier is 2 (smallest) and my system crash (not past POST). Darn, it seems that I will have to OC my memory as well to get my chip higher.

Anybody helps me how to tweak RAM with my board (UD3P)?

Thanks,

D.

What exactly do you want to "tweak" about your RAM?

And have you tried playing with the frequency for your RAM (not just the RAM multiplier)?

I meant OC my memory.

Sorry but I am too new to this. I do not see any option in the board to change the freq of RAM (it is always 800 MHz). I can set DRAM to Manual, but doing that just to change the timing. In the advance control, there are so many options (most of them in Auto), and I have no idea how I can change them to get my RAM at higher freq. The only option that has something similar in advance control is Channel A (or B) Driving Profile, it is Audo by default, and I can select 800, 1033 etc. But even when I select that, the freq shown in the MIT screen is still 800.

What I am missing here? Is it possible that my memory (8G G-Skill DDR2 800) does not have ability to OC???

Thanks,

D.

See where it says DRAM Timing Selectable that needs to bet set to manual
ADvance Timing Control you can tweak more settings.

Hmmm well I've been running my CPU @ 4GHz (445x9) 1.232V CPU-Z idle and 1.28125V set in BIOS for a couple of days now playing games etc (prime95 9 and half hours stable). I went AFK for abit today and when I came back to my comp had restarted. Now is the CPU unstable or did the CPU termination reboot the computer? Because at load this board drops the CPU to 1.200V. In BIOS I have every voltage set to normal except the CPU vcore.

I'm not sure what CPU termination is but is that how it works?

Yeah I saw that, after changing it to Manual, I can adjust the RAM timings. I also filled out my specs.

In the third image you posted, I saw

Memory Frequency (MHz) 800 1200

Does that mean your memory is running OC at 1200 while its stock is 800? I have stock DDR2 800 as well, and if I try to set FSB to high (450 for example) hence memory is OC to much higher than 800, my system can not past POST.

Are you running your system stable?

Thanks,

D.
