CPU run slower than default after BIOS Flash

Specs: Microsoft Windows Vista Ultimate, 2.2 GHz / 4094 MB
I had flashed my BIOS to the new version on the ASUS website and ever since then my CPU is running at 2.2 ghz when it should be at 2.8ghz and my ram running at 400 mhz when its default/proper value (which i set in BIOS as well as cpu freq) is 800mhz.

is it possible to reflash the BIOS and it will run proper again?

64bit OS
DDR2 / 800mhz / 2.1V ram
ASUS M4N72-E mobo which is AM2/AM2+/AM3 sockets compatible

why did u flash bios? No cpu info provided.
Ram is running at 400mhz, 800ddr/2=400mhz.

So you're setting the correct speeds in your cmos/bios setup and they're reverting back to the slower speeds on their own? Or are the correct setting holding in cmos but you've got some diagnostic software that's showing it's slower?

Is this an overclocked system?

Sometimes a bad cmos battery will cause the bios not to hold the settings.

You may need to check the manual to make sure you're taking all the right steps in adjusting the speed.

Oh i guess the ram is running right then. its ddr2 800. I updated thinking the newer bios would utilize my processor better in game shouldnt have flashed it. I have Phenom II 925 quad core 2.8 ghz CPU (Deneb core). It shows in BIOS that its running at 2200 mhz as well even though it is supposed to be 2.8 default. CPUID shows it the same in windows. ASUS tech support said was a problem in the registry which is a mess to fix . they said to pay them 160 for a year of service and they will fix it im not going to do that. but sounded like it was old registry files or something making it run slower than its default speed.

Cool 'n' Quiet at work?

Did you try manually configuring the CPU settings in the BIOS?

It's not the registry if it's showing that speed in the bios also.

Well, did you try manually configuring the CPU settings in the BIOS like I asked? Turn off the stupid AI Overclocking (in other words, set it to MANUAL), then manually enter the CPU multiplier, CPU frequency, DRAM frequency, PCIe frequency, HT link speed, voltages, RAM timings, etc

You kids are so cute when you revert to name-calling but you should probably click your edit button and remove the last sentence. Jam's the only person that can help you. Do you really want to piss him off?

Specifics on bios setup varies with different motherboards. Jam is more familiar with those boards.

I don't know how many people related to this site can help with your problem. But of the ones that have so far responded, Jam is your best bet.

It's all voluntary here. It's not like we get paid.
