opteron 165 or opteron 170 for my spec?

[Y3]

i have been researching for abit and has come to the conclusion that ill give up on the 4400+ 89w as they are almost impossible to locate. will be getting Opteron instead.

notice some thread talking about 170 has different "multiplier". i have no idea what it is. current spec is as follows. should i get opteron165 or 170? will try to fiddle with OC once i get the new cpu. ^^

Anthlon64 3200+
CoolMaster Susurro Fan
ASUS A8N-SLI DELUXE
Samsung DDR400 1GB x 2
160GB Hitachi SataII/8M
XFX 6800GS DDR3 256MB
Antec PS-SP450
X-Fi XtremeMusic
Asus 1608P3S

Thanks in Advance.

The Opteron 165 has a multiplier of 9; the 170 has a multiplier of 10. (I think). Each chip runs at 200 MHz before being "multiplied". The 165, then, is 200MHz x 9 for the 1.8GHz it's rated at; the 170 is 200 MHz x 10 for 2.0GHz. They both have great overclocking potential, especially with the right steppings. I have a 165, and it runs well at 2.4GHz, but some people have gotten theirs a lot higher. The 170 should overclock well also, but more people bought the 165 because it was cheaper and easy to overclock, which invalidates buying the 170 in most cases. Nowadays the prices are much closer together so it doesn't matter so much. In short... either chip will work great for you.

The Opty chips come with very nice HSF's. They have a huge fin block with four thick copper heat pipes running heat away from the chip. I'm using the stock one with no issues. I would recommend, however, using Arctic Silver 5 thermal paste. It seems to work better than the stuff that comes on the HSF originally.

I have seen, in the past, some cooling tests done on Opteron chips with both the stock HSF and various aftermarket HSFs, and the stock HSF actually did as good as, or better, then like... 90% of them. This was a year or so ago and things may be different now, but regardless the stock HSF is a really good one. If you still have your Susurro Fan, you can try running the chip with it installed also, and using a temp monitoring program, compare temps and see which one runs cooler for you.

I think those tests with the opteron heatsink were using a different fan.. as my results of the heatsink are different.

Not sure if it is the mobo or CPU but i have my stock heatsink fan from my opteron on a Sempron 2600 @ 2Ghz and it 10* hotter than my Opeton 170 @ 2.6Ghz... but at load there is only a 5* difference.
