The SL9HA is physically larger and takes some work to get in the socket but it does NOT work in the DL380 G4. Now I have some of those to kick around... Oh well live and learn.
That brings me back to one of my original questions, would it be worth the money (~$30) to go from the 3.6ghz single core to the 2.8 ghz dual core? Or more importantly what are the benefits of switching? I don't know if the drop in speed is worth the doubling of cores.
I'm going to use it to run a Minecraft server, lamp, terraria server, ect. As time goes on I intend on adding some other low performance cost game servers like doom. In short I will be running many applications on it at all times.
I don't really view the price as problem for it, but If it won't benefit me I don't want to waste the money.

Thank you for that pdf, That was what I was wanting to know! I have been running the hyper threaded 3.6Ghz for about 10 months now and they have worked out. I get some kernel panics in Ubuntu 12.04 every now and then that I think are performance related so I may step up to the dual cores now that I know it would be a step up.
