P4C800 Deluxe - P4 3.20E Running at 2.8GHz?

I just got the P4C800 Deluxe, with a P4 3.20E. The BIOS shows it running at 2800 (and Win XP also reports 2.8Ghz).

I have updated the BIOS to 1016.

Is there a BIOS setting I need to adjust to make the CPU run at it's full speed?

Thanks,

Peter Franz.

try adjust your FSB to 230 in the bios which will bring your 3.2E running @ 2.8 up to 3.22ghz. your motherboard can handle it since it's a very good MB and since that CPU is designed to run @ 3.2, so it should have no problems either.

I think they want 3.2 speed using stock FSB. I guess you have to wait for the correct bios to be released.

I can push my DDR400 to 225Mhz, (3.15Ghz) but that is just a "Band-Aid". The system needs to recognize the chip correctly, and it's not. That's the whole base of the problem. The BIOS will see it as a 3.2GHZ chip but will only run it at 2.8GHz. I'm all for overclocking, but I want to push my speed beyond the default speed - not to it.

The funny thing here is that 1016 states it address this issue. From ASUS concerning the 1016 BIOS:

Fix Prescott Locked CPU cant run to highest frequency.

Thanks for the tip. It works great, although I'm still annoyed that it's not detected correctly in the first place. Hopefully they'll get it fixed in the next BIOS update.

Even funnier that when I called ASUS tech support they basically blamed it on the CPU (mislabled CPU, bad CPU ID String, etc.). Now, how probable is that?

To follow-up on this issue. I was running BIOS 1014 and have since flashed to 1016. The problem was the CPU is recognized as a 3.2GHz with that BIOS version, but the multiplier was incorrectly locked at 14 instead of 16. Simply flashed to 1016 BIOS - reboot - reset to system defaults - reboot - enter setup to reconfigured BIOS to my hardware. Works like a champ now

So your Locked multiplier is now 16? No luck for me. I reset to the BIOS defaults, rebooted again, and everything is still the same. Have I missed a step?

Also I noticed that with the FSB set to 230 or 225, the DDR rate dropped down to 266, so I guess I'll leave it at the default for now.

Try a reflash of 1016 - see if that helps you out. Yes, the multiplier was locked, and grayed out, in the BIOS prior to the flash to 1016. Now it's locked, and grayed out, at 16. Download CPU-Z from http://www.cpuid.com/ and see if your processor is indeed what you ordered.

Reflashing didn't help. This is the output from CPU-Z. Looks ok to me...

You got a stubborn board on your hands. Maybe clearing the RTC RAM may help. See section 2.7.2 (page 2-19) of the manual. Boot directly to the A:\ drive and try a reflash again. I see you have a P4C800 Deluxe. However, my board is a P4C800-E Deluxe and the 1016 BIOS fixed the issue for me. If all else fails, RMA it for a P4C800-E. Here's my info:

Clearing the RTC RAM did the trick.

Thanks for all your help!
