I currently have a q6600 in my computer, and I think I should upgrade it. I saw a video by tech yes city, saying it was relatively easy to modify a motherboard to accommodate an lga 771 CPU. I am running a GA-P35C-DS3r. I value my motherboard higher than a cheap xeon (likely x5450). Is there any way I can cut/drill the CPU instead of cutting my socket? I think this is possible, because ebay listings have the actual cpus sliced. I'm going to buy one of these anyway, just because it is just slightly more expensive, and is already done for me.

Thanks!

Yep, all you have to do is search for "fully modded" on eBay to see pictures of how it's supposed to be cut. And use the socket itself to show exactly where and how much.

You only need a small round file to cut the notches into the fiber-reinforced plastic PCB. Those pre-modded chips also have welded pads so if you are DIY you'll also need one of those 771 to 775 stickers. And in any case you'll need a BIOS with the Xeon microcodes, something you'd need even for LGA775 Xeons like the x3370.

Hello!

Theoretically it should work, but my only concern would be that if you were to drill into the side of the CPU to create a notch it would interfere with some of the connecting points on the CPU's LGA (Land Grid Array). Cutting the board socket wouldn't cause any issues, and is a much safer bet in my opinion, but to each his own I suppose.

Also, I've never seen a lga 771 CPU listed on ebay pre cut. That's very interesting.

Anyways, hope I was of some help!
