    Overclocking Opteron 165

    It's reached the point where people look at my system and use words like "quaint" so it's probably time to spend some money and build a new system to last me the next 3 years or so. The Opteron 146s are looking very appealing right now but if it's possible to get something like 2.7GHz from an Opteron 165 then that would probably be better for my usage patterns but I really need the faster chip speed so dual core is a secondary concern.

    Anyone any advice?

    If you can hang on a bit longer, do so. When the first batch of 165s get tested by forum users around the world you'll get a better idea of the performance picture.

    If you don't need dual core then I can't see the point of going past the 146 for a third of the money. The only reasons I can see for going to the 165 are:

    Youve got loads of cash and the difference in price isn't a concern.

    You only upgrade once every couple of years or so (and youve got loads of cash and the difference in price isn't a concern.)

    There are reports of the 165 going close to 3ghz which would make it a fairly awesome machine for the cash. I'm running a 146 at just under 3ghz and its plenty good enough for me. I suppose its getting a nice balance of components, without one bottlenecking the other.

    Almost right. The price is a concern but it's not a dealbreaker.

    Thanks for the info about the 165 getting close to 3GHz, I'll keep my eye out on the forums.

    There's another good reason for going dual core. You actually want to run two CPU hog programs at once. Sometimes I want to run four, but dual core is a step in the right direction, and AFAICS 165 is more like double than treble the 146 (£110 to £230 at Komplett). Seems like a bargain seeing as you don't have to upgrade any other part of the system to run it.

    Aye just saw that price before - its about £100 cheaper there than anywhere else. Quite tempting when you see what 146's are going for on ebay

    1. Isn't it closer to 6 months?

    2. I was born neither good looking nor rich

    I need the best bang per buck and about 3 years life. My usage is generally more workstation oriented hence looking at the Opteron but I like to play games too so I need performance there too. What I don't know is how much gaming performance I lose by going Opteron instead of X2, the FP performance on the Opteron would be very useful but all work and no play isn't much fun and I don't want to make the wrong choice on something I don't expect to replace for years.

    In the here and now you'll get better gaming performance from the Opteron. Games aren't out yet that'll take advantage of the dual core.

    Hah. Komplett now says 5 days for 165 and 10 for 146. US buyers are also mentioning disappearing chips. Appears that AMD didn't realise how popular these were going to be.

    Or.. they did, and knew that over supply would drop prices below the X2 3800 and kill sales for that chip..

    Regarding FP performance of opteron vs X2, the X2 already has much better FP than intel chips, I don't think the opteron would have much more. Essentially the difference is you have a slower speed, but more cache, which basically equals the performance out between the two.

    For somethings the more cache will be better, and you can probably overclock the opteron better (by raising the FSB thingy, not multiplier) but then you probably want better memory to do so, whereas the higher multiplier on the X2 means you don't have to increse the FSB as much to get the same CPU performance gain, which is better for less good memory.

    Another probably insignificant factor is that AFAIK cache is always active, and using up power, whereas the multiplier can be dropped via cool n quiet so the X2 might have some small power/heat savings.

    Cool n Quiet???? Does anyone use that abortion? Say nay.

    Better memory? Well the current consensus is that in the real world tight timings make little difference. And you can always use the divider if you have real pony stuff.

    From reading on other spots there seems to be a fair bit of crack that AMD is discontinuing the 165 with the 170 being the 'budget' chip.
