Upgraded 2 AMD systems to quad today

austinbike · Post by **austinbike** » Sun Nov 23, 2008 3:58 pm

I updated my HTPC from dual core athlon to quad phenom and my workstation from dual core athlon to quad opteron.

Here are the temps:

Was there any noticeable performance gain ?
I was unaware that any Opterons came in socket AM2 , does it fit ( and work ) on all AM2 boards ?

Performance is better on multi threaded programs. On single threaded programs I will see a performance hit (2GHz vs. ~2.5GHz).

The board does support some of the dual core opterons but I knew it would work with the quads too.

All of the 1000 series are in AM2 sockets.

Thats some pretty nice results.
How about power consumption?

Unfortunately I didn't bother with the power consumption.

The server had ~42W before and is now ~65.

The HTPC was never measured before so I have no frame of reference.

your cpu fan idles at over 1100 rpm. Doesn't that seem like a lot?

I thought it was interesting that your hard drive temps dropped in both cases.

Did you change case fans or airflow in any way or is that just a side benefit of reducing total power draw / waste heat from the rest of the system?

That's a good question. What are other people seeing from their fans?

Actually, the server has a 4-pin fan (120mm) and that one is running higher speed in idle. The opteron is 75w acp, the phenom is 65w.
