771 to 775 conversion
« on: November 20, 2013, 08:05:56 AM »
So I have some Xeon 771 Cpu's kicking around all quad cores all bored out of their minds.
I also have a massive amount of 775 motherboards(Dell/HP/Acer) you know the throw away ones but they all are DDR3 and some even are itx.

So I'm going to order the small conversion stickers and start this project I will record the whole build and testing and if its goes up in smoke no big deal they were not being used anyways:)

So over the next bit I will have some fun with this mini project and if they do work I will water cool them and make some custom rigs

LOL, that would be awesome if you could get one fully working. I figure I can still use the 2nd one as a HTPC since I won't need the actual screen part to work as it will stuffed in a cabinet.

This conversion from LGA771 to LGA775 catched my eye, because I own a LGA775 mainboard - but with just DDR1 rams and VIA chipset. Therefore it is clear, that such conversion is not helpfull for so old boards, that did not have support even for C2D, much less anything more modern.

Sad.

But even Xeon E5450 looks pretty good with 12MB of L2 cache, 4 cores and 3GHz clock.

ATM I have only a mediocre experience from oldie MSI 6340 board, that did not support AXP CPUs, to make them run in it. They does, but in the end, the AXP at 1100MHz (brutal downclock because of FSB 100MHz) is slower that just Athlon at 900MHz...!

Not good. Probably time to inject the CPU support code into the bios to try again...

Let's hope the conversion went much better!

I did get 2 working sorry they were built and bought within an hour of eachother. The cheap adapters on ebay (literally tape and some copper holes) worked like a charm

Got 2 cheap dell towers to run quadcores.

If you want to try yourself pick up the tape online

anything like that will work and again I have lots of spare CPU's so you buy a multipack of tape I send you a few cpus :)

Congratulations! Amazing to see thing like this work so well. Looks like the Intel is just creating some artificial compatibility limitations w/o there are being any real reason for it.

Good work, John!  ;)

That's awesome! Good to put some of the 771 CPU's to use.

I'm in the process of getting rid of all my C2D systems, they just suck up to much power. Going to try and build a BayTrail J1900 machine for my HTPC/File Server

I heard about this and wanted to try it out on a old board of mine. The E5450 looks to be the cpu worthwhile.

Anyone have one? I am interested in buying and trying this out.
