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?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.

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?
Yes, this is normal when speedstep is turned on. Your CPU is downclocking to save power and reduce heat.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?
There really isn't a preferred bios per se, but you just will have to try them out and see how they work out for you. I use Ket's modded bios over at the xtreme forums. Also, if you are getting 60's with a waterblock, then I would say that something is wrong or misaligned. You should reseat the waterblock again just to make sure. I have a p5q Deluxe with a q6600 g0 and it's running 1.4v stable in the mid 30's (at idle), mid 40's during use right now and that's with an 8800 Ultra in the loop as well.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.
Well, you can disable any onboard motherboard devices you won't be using, like if you have an external sound card then you can disable the onboard audio. Also, you should enable ACPI 2.0 if it isn't already. Other than that, I don't think there's anything.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?
If you are worried about memory compatibility then you might want to check out Ket's mbios'. He takes care of a lot of them in those modified bioses of his.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?
I flashed my P5Q Pro to the most recent official BIOS on the site, as I usually do with a new mobo, and that was 1613... having absolutely 0 problems with it.Question: as others have asked above, which BIOS version is most recommended? I'm using 1613, straight off Asus' site.

Well my power supply died and took my motherboard with it or vise versa. Cost me about $40 to ship my power supply back to Coasair for a replacement. After I received the power supply I discovered my P5Q died too.Care to elaborate ?
Remember the processor has its own FSB limits as well. Most quads won't go above 475. In fact I know many who can't get their quads above 450MHz on any motherboard.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.
I'm watercooling @ 3.6ghz already. 9 * 400, but my calculation shows a 5:6 ratio.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.
