CPU running slow and keyboard not found!

post #1 of 19
Thread Starter 
Hi I just bought a AMD Phenom II X4 955 CPU for my M2N-SLI-Deluxe mobo. I have cleared the RTC RAM, then updated the bios to 5001 which makes my mobo support AM3 CPU's, installed the new CPU and cleared the RTC RAM again. But now when i check CPU-Z it shows that my CPU is only running at 804MHz and the multiplyer is set to 4. So I try to go to the BIOS and change it to X16 instead of X4. But when it does enter BIOS the keyboard does not work anymore. Also, I get this error sometimes:
"..The fileis corrupt or missing
<windows root>\\system32\
toskrnl.exe
Please install a copy of the above file"

So How can i get my CPU running at full speed and how do I get that error fixed? Now my memory is 3Gb i have 4Gb installed. Before putting the new CPU the memory was 3.5Gb now it's down to 3Gb. I need to solve this too. the memory says something about unganged DC mode, what is that?
I cant use my keyboard in the BIOS by the way.

well i wont be able to get a new mobo, but is there a solution to this. i cleared the cmos and put in the CPU but when i booted the computer, it showed that file listed as missing or corrupted i can get past that by taking out the keyboard. but my CPU is still running very slow. My old dual core CPU can run way faster than this. what can i do?

i want to be able to enter the bios.

You have to use windows 64 bit to detect more than 3gb of ram.

That CPU is not exactly supported by that motherboard. If you look at the CPU support page on the Asus site you will see that the 945 is the fastest CPU that will work in that board without any tweeking. The 955 will work, but you will need to do a few things to get it going. Heres the thread you need to read to see how its done.

well if you do check on the CPU compatibility page, it shows the AMD Phenom II X4 955, is supported. well i'm now able to change BIOS settings. so i changed the multiplier to 16 and the voltage to 1.35. then i restarted and turned on CPU-Z. And it is STILL at X4 multiplier. how the **** am i supposed to get it to 3.2Gz I dont want to think that i wasted my money on this. I need some simple, easy to follow steps, (i couldn't understand that thread, too many things) to get my CPU to 3.2Gz.

First things first, I hope you have a ps/2 keyboard around. Should keep you from losing capabilities in the bios.

Also, check this particular post out regarding the 955 and your mobo: http://www.overclock.net/7594611-post3945.html

so how do i keep it at 3.2Ghz? it always downclocks after the computer starts up.

since i dont have any games on the computer to test this, does the nvidia control panel actually make it faster or is it just for show?
