Are the opterons multiplier unlocked? I was just wondering. Lets just say 275mhz is a good round about number that we can safely say is what most performance RAM can safely achieve. I mean, i think thats a good realistic number. Assuming athlons are good overclockers (most say they are) that would mean a 2.47 max speed for the opteron (9x multiplier) and a 2.75 for the X2 (10x multiplier). Of course we all know that 2.7 is dangerous no matter what anyone says, but are there any over clcokers out there that would agree with me that the X2 would achieve 2.4 ghz with a lower voltage? One chip needs 600 mhz to reach 2.4ghz and another needs 400. One might get away with overclocking and not need to overvolt the CPU. I think that one is the best chip despite saving a few bucks on the other. What do ya'll think? The other issue is the increased L2 cache. One chip disspiates 110W and the other 89 watts. Does the opteron come with a different HS/fan? Its safe to assume that a chip that disspiates 110 watts needs a Pentium class cooler. That means the opteron could be a little more expensive than one would anticipate. Just my thoughts. I am really interested in the Opteron vice the 3800 although it really wouldnt help me with video encoding though. I dont care.
 
That really changes the dynamics of what it is that I want to do. It really does. So they are unlocked both up and down? That sounds almost too good to be true. Is there any compatibility issues between opterons (939 of course) and X2s when it comes to mobos? Does this mean if the mobo is X2 compatible it will take an opteron with no need for a bios update? I have seen your posts and I can tell you know your shit. What do you think about heat dissipation difference between the 165 and the X2 3800? What kind of heat will 110W be in comparison to 89W? Do you think I would need to buy an aftermarket cooler should I choose to OC to 2.4ghz?
 
yes the opteron will work in your system 100%

( I asked the same question and got the same answer above when I asked :lol: )

currently have a opty 165 in my old lady's pc oc to 2.6 on air, because I just updated (whole new system) with 170 was going to go with the 180 but decided against it saved the cash and went with a liquid cooling solution.
Going to wait a while and let the arctic siliver reach its 200hr mark before I start to OC it, planning to go to the 3.0 if i can. But it will be a slow process!
 
By stock Opty 165 is slower, but once overclocked it can go higher than X2 3800+ in most cases.

I too have researched this. The key difference between the X2 3800+, 4000+, and I believe one of the 4200+ models and the optys is that all the optys have 2x1mb L2 cache. The X2s I listed have 2x512kb L2 caches. Although the opty 165 is 200MHz slower, its got the 2x1mb cache instead of 2x512kb.
 
so which one would you guys go with? opti 165 or x2 3800.....

i dont want to OC, but I want super good performance when gaming....I also thought about just getting a single core for now, and waiting for dual cores software and games to become more popular so then i can upgrade my cpu again
 
If you want to go dual core, which I'd recommend because they're mature enough now to have most of the technologies that'll hold you over for a while. I'd go Opteron 165 because you always can OC in the future, even if you don't now, and because of the bigger cache. If you want pure gaming, go single core, as much as I hate to say that, but if you want to have great gaming and the ability to do something else at the same time, I'd go dual core. Besides, I'm sure a lot more stuff will be written for dual core in the future and you won't have to upgrade when they do.

Essentially, go opty 165 if you want dual, go single if you want pure gaming.
