I currently have a socket 939 Athlon 64 4000+ Clawhammer, and would like to get a performance boost without a platform change.
The opteron 170 is down to $122.99 at newegg, but it runs at 2.0 GHz, while my 4000+ runs at 2.4. However I have also read that these are great overclockers. Would I have a significant increase in performance if it doesn't
overclock higher than 2.6-2.8GHz?
It would be used mostly for gaming and video encoding.
Well, I don't know a lot about opterons, but I'm assuming they don't have unlocked multipliers, so I'm thinking that I won't be able to overclock very high without putting to much stress on the motherboard and memory.
I would have to go over 2.4 GHz to see any increase at all in single threaded
games, and would like to go 2.6-2.8, but I don't think my parts cand handle it.
Just use a memory divider, say 166-5/6. With a 10x multiplier you'll have 200mhz on the memory and 240mhz on the core. You can go up from there if you wish but at that speed it does put you on the same playing field as your 4000.
I got the Opteron 170 for 114$. I currently have it running at 2.4GHz (same as the 4000+) on stock voltage. My ram is is overclocking very well. The FSB is at 240, and I have not needed to use a memory divider yet.
At stock settings it idles at 38C and goes to 52C under full load. These temps seem high to me, but they didn't change at all after overclocking.
No buyers remorse yet, and I'll like this proc even better after I get it running faster. I'll continue working on it and see how high it can go.
