I've bought T5500 memory from this seller: http://www.ebay.com/usr/1-800-4-memory
But I usually just find a listing with the "Make Offer" option and try to get it for around $5 per Gb.

Al and I ran some benchmarks of the T5500 against my I7 3930K @ 4.2G. We used Universe@home since the WU are short and a consistent length. Here are the results.
3930K @ 4.2G
1814.6s time per WU
2116.5 credits per thread
25,398 credits/day total
T5500 E5650 2.66G
3005.6s time per WU
1277.5 credits per thread
30,659 credits/day total
T5500 E5675 3.06G
2683.6s time per WU
1431 credits per thread
34346 credits/day total
Either T5500 will out perform the I7 3930K and the entire system costs less than the I7-3930K processor alone
Yeah, but then ya gotta pay for the electricity to run it!
That's why I parted with all my gpus.
I tested my dual X5650 T5500 a few days ago - it pulls 250-285 watts measured at the UPS with a full CPU load and idle GPU. Mine typically bounces between 2.8 and 2.9GHz... Intel lists the max turbo speed as 3.06GHz.
Has anyone tried the upgraded Dell performance heatsink? I'm curious if that would allow the Xeons to stretch their legs a bit.
And I turned off all my miners

This is the stock heatsink: https://www.google.com/search?q=t021...iw=320&bih=504
This thread started with me trying to fish for input on a dual xeon build from mobo up. So i thought I'd give it an update where you can see all your input manifested.
I now have a dell t5500 next to me. It has dual x5650s and currently 36gb of ram (until 8gb 2r gets cheaper). It came with a wd 10k raptor (could have been worse) and no OS. I have been playing around with a bunch of Linux distros this past month and linux mint mate went on it right away and easily, (this is with 12gb of ram at the time). I added a few projects to boinc, WCG, yafu and some others. I didn't give it too much time to settle in and get a lot of different apps/projects/tasks but I was really impressed by how little ram it used. I decided i didn't want to fuss with more up to date nvidia drivers on linux and installed win 7 64bit after some tail chasing (when installing from USB drive partition issues).
I popped a gtx 750ti in it between Linux and Windows, it has at least 1 pcie 6pin, i thought I saw two but i got a near reference model that requires no extra power. It is still limited to 38.5watts in vbios though.
So right now its pretty happy except the 2nd cpu well cpu1 reads anywhere from 15c-30c higher than my cpu0 cores. Cpu0 doesn't ever seem to break 70c while Cpu1 spends most of its time in the upper 70s and 80s. Unless I'm mistaken cpu0 is on the mobo and cpu1 is on the riser. The mobo mounted cpu doesn't even have a fan attached to the heatsink, while cpu1 on the riser has a much fancier heatsink and well who knows how good that fan is. I'm not quite sure what my temp solution is going to be but there will definitely be a change. I've ran it with the side panel off and on, not much different for cpu1, wasn't paying attention to cpu0. In a new case I don't see why an aftermarket 1366 cooler like a Cooler master 212 wouldn't work/fit? Maybe dimm clearances?
Let us know if you cure the heat problem. Both Bryan and I see the same issue with cpu 1. To be honest, I'm not too concerned about it.
Edit: I did change the thermal paste on that processor with no change in temps at all.
