Been having a play with my P5Q-E and Q9550 but whatever I do I can't get it stable to 450FSB
425*8.5 is fine, 450*8.5 = Fail
Will run CPU test in OCCT, but mix and mem test fail almost instantly, it's not the memory as it's rated and tested higher then this and it's not the CPU as it passes the CPU test.
Annoying as I updated from a P35 based board hoping for a higher FSB with my Quad only to hit the exact same 450fsb wall.
P5Q-E (Bios 1406)
4GB G-Skill F2 8500
I've been all the way up to 499FSB. 500 is a little shaky, but 499 really works. I wonder what's up. If anything I would put the power requirements quite a bit less on your new proc. than on my old Q6700. What have you got your NB voltage at?
What BIOS are you using?
Try typing in the number directly instead of pressing enter.Problem: I can't access overclock settings in the BIOS. At all. I've gone into the AI Tweaker menu, set AI Overclock Tuner to Manual, then attempted to change CPU Ratio Setting (currently on Auto, by default) only to click enter on my keyboard, and... nothing. No menu pops up. I can't change the CPU Ratio Setting (or FSB Frequency, for that matter.) It appears locked on Auto. Have I missed a prerequisite besides setting AI Overclock Tuner to manual?
That worked, thanks. But now CPUZ is reporting my Q6600's core speed as fluctuating between 2.4Ghz (stock speed) and 3.2 Ghz (which is what I'm aiming for: CPUM at 8, FSB at 400.) Is this normal?
As others have asked, what is the preferred BIOS for this board? What BIOS version are people having the best luck with? My new (used) Q6600 is BARELY (not really) stable at 3.6ghz and 1.5v. Temps are in the 60's on water. Its a G0 from the L7 batch so i was expecting a bit more, or at least 3.6ghz with less voltage...its Prime stable for over an hour but one core will fail eventually.
General performance or stability enhancements. I've gone through now and disabled the IDE HDD boot check and ExpressGate, which helps boot time considerably. Anything else along those lines?
wow long time i've last posted on [H]... so well, here I am
I'm planing my new rig, including 8gb of RAM and an Asus P5Q-E. I've read a lot of memory incompatibilities, especially when overclocking a bit (not that much, just a tiny little squeeze ) and using 4x2gb RAM. After surfing through the QVL and the range of products my local online dealers here in Switzerland carry I found the OCZ Memory 2x 2GB KIT PC2-6400 Platinum-Series| (OCZ2P8004GK).
Since I can't just return the memory if it does not please me I'd like to know if this combination (4x2gb OCZ2P8004GK on P5Q-E) works without any problems? It is on the QVL and should therefore work, but I've read some misleading posts in different forums and am thus a bit unsure what to think of this combination.
Is there anybody that knows this combination and can give me some advice? go for it or not?
Question: as others have asked above, which BIOS version is most recommended? I'm using 1613, straight off Asus' site.

Care to elaborate ?
Dont think so. Its a Q9650 running 4.2ghz at only 1.25v. Thats at 467x9. If i lower the multi to 8 and make the FSB 500 for 8x500 = 4.0ghz, even with 1.25v....still wont be IBT stable.
333fsb x 9 = 3.0ghz, or 400fsb x 8 = 3.2ghz, or if youre cpu/heatsink are good enough maybe even 400fsb x 9 = 3.6ghz...setting the fsb to 400 and moving the multiplier would be best since thats the speed of your ram and you can keep the fsb/ram in a 1:1 ratio. I also am assuming you want to OC.
