Just wanted to share my experience with a really interesting and also budget friendly way to give new life to older LGA 775 based computers such as those with a Core 2 Duo cpu.
I had an old computer running a Core 2 Duo e8200 that had been overlocked from 2.66GHz to 3.4Gz for the last 6 or so years. It had recently been acting up, probably due to the increased voltage and long duration that it had been OCed.
My options were either to throw it away or see if I could get a replacement cpu. While looking around for an LGA 775 compatible cpu I found two things:
- LGA 775 cpus are incredibly expensive for their age
- There were some interesting article about using an adapter with LGA 771 Xeon cpus to run in an LGA 775 motherboard.
This second point certainly piqued my interest, especially since I found that these Xeon cpus which once sold for $999 USD were now selling on Ebay and Aliexpress for ~$40 USD.
Since my old PC has a P5K SE motherboard I had to do some bios hacking to add Xeon cpu microcode, but it was fairly easy and I got to add AHCI support to the motherboard to make the SSD work better at the same time.
I decided on a Xeon E5450 SLBBM stepping which is a quad core running @ 3.0GHz stock and equivalent of a Core 2 Quad QX9650.
I installed the cpu last night with a little bit of help from my wife to cut the tiny plastic bits out that prevent LGA 771 CPUs from fitting. It runs really well now, I have yet to overlock but I have a pretty hefty HSF so I am sure I can boost it to 3.8GHz or so with no problem.
Anyway just thought I would share my experience with this as it's an incredibly cheap upgrade for an older PC that can give it a bit more life.
