Ive got a E5310 off ebay for 5$ and a as-rock g31m-gs motherboard for 30$ and the mod for 3$.I put it all together it didnt work i take the cpu out put in a e6400 core 2 dou and update the bios to version 1.9 and i take the core 2 dou out and put the xeon back in and it boots but in the bios it 1.2ghz not 1.6ghz i boot into windows and i see windows see the cpu but only 2 core i open cpu z it says e5310 but core temp says xeon 5110 but on all of them it says 2 core btw the cpu head was scratched but it said e5310. any ideas im going in blind

I'm glad you have a quad to fall back on. Doesn't give back the time or alleviate the frustration trying to figure out whats wrong. I spent a lot of time and some extra money buying a second mobo because a dysfunctional CPU. And then I still had to go and buy another CPU. I too am happy with the end result, just wish it would have worked first time around.

How deep was the cut into the PCB? Did they take out any capacitors or resistors on the bottom?

"I'd start by adding the Xeon micro codes to your bios. Real easy to do because I think that's an AMI bios. Takes 3 minutes. Did it myself last night.

http://www.overclock.net/t/1431723/mod-lga775-support-f...

There's also fixes for the number of cores reporting, but start with the codes."

Done the only thing that has changed is now my bios no longer say press f2 to enter.
How do i fix my cores and clock speed

I got the CPU back to 1.6ghz i had to move a jumper on the motherboard for it to to work it was at 800fsb not 1066fsb now all i need it my 2 missing cores then the cpu is fully working

The dreaded manual fsb jumper. I guess it cost less than a proper bios. What happens if you set it to 1333? Easy overclock?

This answer came from bailw on overclock dot net:

Go into MSCONFIG (CLick on Start, type MSCONFIG in the earch box, heit enter, in the window that opens click on the Boot tab, click on Advanced Options, in upper left, click the box and Select 4.

Otherwise, ive heard reinstalling windows fixes this too. A bit dramatic if you ask me.

Hope it helps.

I installed again lass night still 2 core btw in the bios I see the cpu it's reported by the bios and the full cache shows up in the bios but in windows only half of the cache shows up in windows

It took me 3 try's of reseating the cpu in the socket to get it to post for the first time with the xeon

I've read all 400+ pages of the thread at OCN and haven't heard of anyone getting half the CPU to work but not all of it. This definitely is a hardware issue and I'd look at 3 things.
1. Double check the socket modification. If you had to seat it 3 times before it worked, try again. Cut a little more back where the tabs were.
2. Double check the sticker alignment. Make sure other pads on the CPU are lined up with the holes in the sticker.
3. The CPU could be broken. If you have access to another 775 board, try it on that. If you don't want to modify another mobo, you can notch the Xeon to fit in a stock 775 board. It isn't pretty but I didn't notice any difference on the chip I did it to. Granted that chip didn't overclock before I notched it and still didn't after.

Or, since the Xeon was only $5, buy another one and see if that one works. If not, then you know its something with the mobo.

If I put the notch in the cpu I'll need to use a mill to get a nice cut but the I got the asrock board because it support quad cores I have a few 775 motherboards but the have a limitation of being dell,hp,Emachine I'll try reseating it later but before I installed the xeon or even did the mod to the board I was running a core to duo e6400 and after moding the socket the cpu would no longer post in the asrock board but I'm gonna test it in the emachine I pulled it from to test the asrock board NOTE THIS all parts in this build was a ebay find I got all the parts for a sum of 47$ I had the gtx 550 ti and psu before I built the pc and I have a pentium d 925 that's a 3ghz dual core and it was the first chip I ever tryed to overclock and you now it's a dual core but after my first attempt to overclock the cpu had a core die "ya my first idea to overclock was to up the core voltage right up to 1.5v on a evga 680i sli board that or it was a 780i sli it had 3 pci e x16 ports on it but back the post my full cache didn't show up In the 680i bios with the pd but with my xeon i see all the cache in the bios. Big note here I milo get have the 680i a power surge killed it back in 2010

Might be worth getting a magnifying glass and really checking the mobo socket. Look for bent pins or small pieces of plastic from cutting the tabs that may have found their way behind the pins. The E6400 should still work after this mod.

If you have used parts that are not tried and tested, then cross testing is the only way to know if the mobo or the cpu is at fault. Look for G31 or G33 mobos on those HP and dells. They might work, might not if they don't support any quad cpus. When they want them to be only dual core machines, they use less power components that the quads need. It saves them money.

I just used a hand dremel to notch mine. A router table would have been even better, but this can be done with a hand file if you have one small enough. Use the E6400 as a template to know where to notch and start small. Try it and keep shaving away little layers till it drops in the socket nicely.

I took the pics of it but I had a q9400 sitting on my desk I thought it was dead the mobo didn't post when I installed the first time I had the wrong fsb setting fixed it and the q9400 boots up like a champ I'll give up on my xeon for now but I'll probably just have fun with the core 2 quad I found 3 mouths ago for 20$ so I'm happy with it
