Nice clocks dude

I just sold my x48 as the FSB wall was holding back my Q9550
I'll be getting a P45 UD3P in a couple of days and will try to use your settings

That said, might I ask why your FSB voltage is so high? I've always heard that 1.4v is the absolute maximum you want to go when using 45nm chips and that you can usually achieve similar clocks with much less... have you tried it with less?

Whats the CPU voltage within Windows? And is that a C1 or E0?

Nice, I'm going to try this when I get home, haven't been able to get 4Ghz stable yet on my C1.. (damn second core keeps failing)
I would also like to know if this is C1 or E0

Thanks for posting!

Something like 1.32v idle and 1.344 load i think.

Nice clocks dude....I had the very same choice on mobos when I was shopping for one. I ultimately choose the UD3P. Now I am completely stable at 4.3ghz with 1.36vcore.

I've had to use 1.4 FSB Term on mine to achieve anything over 3.83Ghz, it's been going strong for over half a year now w/ no problems.

He's showing LLC is disabled so I don't think he's getting any vBoost, assuming the P5Q Pro does the vBoost.

Nice clocks Doat

P5Q should do vDrop and not boost.. I know my P5Q-E drops about 0,1v on load from what I've set in BIOS.

nice going m8, i only need about that to get to 4.3ghz too on my ud3r.

bit more to chipset tho.

I do not know my voltage exactly but step speed is on so during idle according to coretemp my volts are 1.1000 but i set them to 1.3500 in bios. From what my friend tells me i have the magical q9550 with the VID of 1.1000 and it is an E0 stepping. I will try to lower my volts gradually sometime soon. Thank you all.

I just dropped my volts to 1.33V stable.

Wow. 1.1 is crazy. My VID is 1.25. But I can run it at 3950mhz (and climbing) on my 780i. Wanna trade??

For finding your real voltage, look into CPU-Z. Core Temp only shows the VID.

Yea i need to download that.
EDIT: I just found it in my documents lol, it says core voltage is 1.304V

Nice. I'm at 3920mhz and 1.328V right now. Still tweaking as RAM was a problem before. Now at 1150mhz 1.95V.

I dont like having my ram clocked to 943MHZ from 800 but when i touched them they just felt warm maybe because my radiator is mounted on the top of my case and the fans are right above the ram.

Where did you get the GTL stetting in the BIOS? The P5Q Pro is not supposed to have them. At least not the NB GTL.

I found the settings from searching and what do i need a screenshot of? CPUZ?

We have almost same settings with my P5Q Deluxe. However, my CPU Vcore is 1.2875v, FSB termination at 1.26v and NB Voltage at 1.24v.

Validation, speed step is on so right now i am at idle, which clocks my cpu down to stock speed but look at the bus speed.
