Motherboard reading CPU wrong

Hello everyone,

I recently installed a Intel I7 3930K to replace my Intel Xeon E5-2680 for increased single core performance. After reformatting the hard drive, removing the CMOS Battery 3 times and BIOS changes, the computer keeps setting the perimeters of the CPU to the old Xeon processor (clocking the CPU at 2.70 ghz instead of the 3930k's default 3.20 ghz).

If anyone knows how to do some kind of Motherboard or Chip reset to make the system recognize and use the defaults of the 3930K instead of the old CPU's settings, please let me know!

Thank you,
flaiR

If you looked at the PDF I linked, there are four versions of the motherboard and two versions of the processor. The OP has the fourth version of the motherboard and each version of the processor requires a specific BIOS version. Depending on which version of the processor the OP has, that determines which BIOS version is required.

Again, I do not know if this is even the issue. It's just a thought on my part. Why CPU-Z and that PDF do not show similar BIOS versions, again, I don't know.

The power was disconnected when I removed the CMOS Battery, but I have never checked for any CMOS pins on the board. If I find some, would it be better to touch them together with the screwdriver or just switch the 2-pin head from pins 1 & 2 to pins 2 & 3 while holding the power button?

It says that the BIOS version is SIX7910J.86A.0650.2014.0307.0138 if that means anything to you.

I just found a jumper on a 3-pin slot that said "BIOS CFG", which I assumed would be like a CMOS pin layout. I proceeded to move the jumper from pins 1 & 2 to pins 2 & 3, hold the power button for about 10 seconds, then put it back to normal. I do not see any new results and I'm still confused as to what could make my system do this to my CPU...

CPU-Z shows the following:

Model: DX79TO - AAG28805-402
Version: SIX7910J.86A.0650.2014.0307.0138

That seems like a long BIOS Version number. Maybe it is though. Mine looks like this:

You are right. I am not as familiar with Intel naming conventions. I guess you could visit their website and look for your motherboard and see if a more current BIOS is available. I am not sure what Wolfshadw was referring to above, maybe he will jump back in.

My BIOS is always up to date and downloading the latest drivers just says that my machine already has that version. My main concern with all this is it's making games slower than they should be. I've seen people with old i3's get better FPS than me and even seen machines the same as mine get much better frames in the same games I currently play (the CPU and GPU's on the tested machines were not overclocked, like mine). I just don't understand why such a high-end system struggles to play most games well.

Specs:
CPU: i7 3930K
GPU: GTX 1070
RAM: 4x4 16GB's - 1333mhz
PSU: Cougar CMX 1000W
HDD: WD Blue 1TB - 7200 RPM
