Will HPZ800 take Intel Xeon X5690 CPU?

[chucklor]

Great thread! I'm in the same boat. I just purchased two intel Xeon X5690 CPU without realizing the higher power requirements. Okay, so is the 463981-001 heat compatible with the Z800? I mean, will I have to remove the RAM memory fan out?

Chuck,

No one has ever responded that the Z400 "Performance" heatsink/fan you refer to will fit in the Z800, but its mounting plate is perfect (same sockets for both).  I did the experiment for the Z600 and found it was just about 3/8" too tall and the lid would not reliably be able to close if you used that in a Z600 because the fancy handle mechanism projected into the case too much (ran fine with the lid off).

The Z800 is a much thicker case so that won't be a problem.  It will be the other stuff around it that might get in the way.

Spend the $25.00 to buy one off eBay and let us know......

Okay, I just upgraded to dual X5690 CPU(s) with my existing 463981-001 heat sink. However, when I boot my computer it still says:

517-Lower Power CPU Heatsink(s) detected for High Power CPU(s)
F1: Boot

Any suggestion?

You have the following options at your disposal:

- Install the correct heatsink / fan components for the higher performance CPU's. if you can find them, they tend to be a bit pricey.

- Deal with the F1 error on restart and knowingly run the system with heat sinks that are not large enough to keep the CPU cool under heavier load.

- Install a jumper wire on the connecting plug of each fan to "trick" the computer into thinking you have the higher performance fans. You won't get a prompt at boot, but you're still running the machine wth underpowered fans / heatsinks.

- Revert back to the lower performance CPU's.

I installed the jumper wire and have been running my system for a year or so without issue. I also don't load the Z800 very heavily in terms of CPU workload - it's a virtualization host and I have no heavy-hitting guests on it to speak of. I do have ONE guest with a large quantity of CPU and RAM allocated that I use to transcode media files. When it runs, it will run at a constant CPU load of around 85-90% for hours at a time. It has never caused me an issue.
