Will a AMD64 socket 939 motherboard run a Opteron 939 CPU?

Yes they will. Any Socket 939 motherboard will run the socket 939 (1xx) Opterons.

I wouldn't say Any s939 motherboard will work, but I would say most new ones. Always look at compatability issues before you purchase.[/i]

Thats why newegg is so great. You can read hundreds of reviews from people who have already purchased the items. You can see there raves and their complaints. Most of them list their system components, this way you know if your stuff is compatible or not.

Yes most S939 mobos will. The only thing you may need to do is update your BIOS to the newest revision. I have an Asus A8V Delux running an Opteron 175 (Duel Core) overclocked to 2.75 and it works flawlessly.

hmm, that is a good idea. Does windows see it as Opteron? or just someother stuff, like amd, xxx???

Windows recognises it as an Opteron  

My understanding is that any 939 board should technically support any 939 cpu (including 939 opterons), but that licensing restrictions prevent manufacturers from "supporting" opterons used in desktop 939 mb's. They don't want businesses stocking up their server rooms on cheap desktop parts.

All the major enthusiast boards support the opteron, and at worst you only need to upgrade the bios to recognize your opty. My opty works great (except it won't overclock as high as everyone elses's seems to).

Yes windows does see it as the proper chip and everything.

What opty, and mb are you using? What is your overclock?

So what is the big rave about using an Optoron on a 939 MoBo???
Whats the big Deal?

Generaly speaking the Opterons are better CPUs. They have higher quality control standards that they have to pass. That being said, they overclock better, run cooler, and are more stable. For instance my A64 3200 would crap out in Prime95 after a week or so. That was on stock settings and all!! My Opteron has been overclocked to 2.75, running an instance of Prime95 on each core for over a month now. My CPU temp is only 46 Degrees, and my office/sauna is almost unbearable to stay in. Mind you winter here in Edmonton hasn't been that cold but the heat is more then welcome!!!! I run Prime all day long. Even when I start up other programs. The only time I stop Prime is when I play games. My system is rock stable. I'll never go back to a consumer level CPU again. EVER!!!

So... from the current forum, I guess the Opterons for S939 come in 1XX flavor only?
By the way, are you perhaps from Cairns then?

Carins? I'm not sure about the 2xx Opties being s939 or s940. Never had a look at one to be honest. Anyone??

Opterons are only 1xx type for s939 (there is also s940 avail on 1xx) they have single and dual core for s939, offer 1mb L2 cache for single instead of 512mb L2 for A64, they aren't worth the premium if you already have an A64 at similar speed,... they overclock slightly better and have 2x the cache, but most A64 can overclock especially the venice and will get comparable results. If looking for a new build, might be worth considering,... though they will add $$$ quick to build. If you have a s939 board and want a bit more life out of it,... then it is a nice easy way to upgrade to a dual core chip with more cache and overclocking ability. Always check your motherboard site for true verification of compatibility but most should be fine  

Hi there I just purchased an opteron 165x2 socket 939. I have a gateway GM4019e. It contains an Athlon 3500+ and a foxconn mobo socket 939. I just want to double check that I will not have any issues when I go to install.
Thanks
