Pretty good price on these. I picked up one yesterday to upgrade my MAME machine. Thinking about getting another to split off some stats tasks but can't quite justify that yet.

I have 2 Z600s. More room inside and the cooling solution is better than the T5500s. I like'em.. especially at that price.

Tempting! The only downside is the memory is 6x4gb, which is only 1gb/thread. And it has only 6 slots, so the DIMMs would have to be replaced to increase the RAM. It looks like it needs PC3-10600 DDR3-1333 ECC, which costs about $100 on ebay for 6x8gb.

Well heck. I thought that was too good of deal. It was just a 2 CPU upgrade kit. Not a full system.

These CPU coolers work great for the CPU on the motherboard, better than the Z600. I need to see if they'll fit on the riser CPU and still keep a fan on riser RAM.

If it's running WIndows, check the Power Options. It may be running Power Saver mode. If so, that's it. Set it to High Performance

If that's not it, run a monitor to show what the core temps are while BOINC is running. See what core temps and power use are. BTW, I do have the case fans set to like 75% in the BIOS and the case cover must be on to get proper air flow.

Not very familiar with the two chassis. What are the pros/cons of the Dell T5500 vs HP Z600?

The Z600/Z800 have both CPUs mounted on the motherboard and each CPU uses the same type of CPU cooler, which is proprietary. Another heatsink may fit but the fan has a special plug and I'm not sure whether it will boot if it's not plugged in.

The T5500 has 1 CPU mounted on the motherboard and comes with a crummy aluminum heatsink. The one I linked to works much better. The 2nd CPU and RAM bank must be mounted on a special riser. The CPU cooling on the riser CPU has something to be desired. They seem to be selling a little cheaper than the Z600s though.

I've got a T5500 and a T7500 - the 7500 has a 2xdual hexcore procs and 48Gb Ram. I like them as they are well put together and really very quiet under full load. I'm certainly hoping the HP one is similar.

here is a T7500 I was looking at also.

I just realized the ebay item I linked to was only a 2 CPU upgrade kit, not a complete system. Thought that price was too good to be true. Sorry.

BTW, I still have some RAM available for these systems. 9x 4GB DIMMS I think.

I went digging around on google for images of the guts of both. I have to say, the layout of the Z600 looks less cramped.

Can either of these actually fit the length of a modern GPU? And power connectors?
