Hey guys.
So I have this Q9550 E0 sitting on an Asus P5Q Deluxe (P45) mobo.
I had it running happily at 4Ghz for years, with these voltages.
CPU 1.3v
NBcore 1.35v
FSB Termination 1.56V
The RAM I was using is two sticks of OCZ Platinum DDR2-1000 5-5-5-18 2.1V
The FSB was running at 471mhz and the ram with 1:1 ratio at 942mhz.
Now the fun starts here, when I got from a friend two sticks of 2X1GB from Teamgroup, models Xtreme, in order to go to 6GBs which seems to be needed for games lately.
As a good(?) overclocker, I set everything at stock and proceeded to see if the RAM sticks can actually work with each other. So I set them at relaxed 5-5-5-18 with 1.9V for start at 800Mhz. They worked fine. Memtest reported everything OK, Prime95 the same.
Now I upped the RAM frequency to DDR2-1000Mhz, set the voltage to 2.2V and tested again. The result was the same. Everything OK.
After seeing that the RAM worked OK, I set the cpu multi to 6X to see what FSB I could get. I went straight to 400Mhz with little voltage and it worked fine.
The problem is that it stayed there. If I even go to 405, no matter what voltage I throw at it, it is not stable. Prime95 with large FFT, gives errors after a few minutes and games crash after a while.
To give some specific numbers, I tried up to
FSB 433mhz
CPU 1.25V with X6 multi
NBcore 1.5V
FSB Termination 1.7V
It does not get stable no matter what.
Am I fighting a lost cause here guys or what?
If I get 2X 2GB memory sticks, will I go any further? Maybe the 2X2GB on one channel and 2X1GB on the other are confusing it?
I mean I know that you can't really go as far with four memory sticks, in terms of FSB overclocking, but 600Mhz less? :S
Thanks for your time!
