Anyone have a source for an AMD FX-55, or one to sell? Looking to reuse some hardware for a NAS and would like to max out the Foxconn NF4UK8AA-8EKRS 939 MB I'm using. I think that is the fastest CPU that will go in that board or does anyone know better?

Thanks,
Stan

At this point, Ebay will be your best bet if you're looking for the FX-55. Then again, for a NAS, you don't need a high-end CPU.

Probably the only FX-55's you're going to find are going to be on ebay. There is usually 1 or 2 up for auction. Sometimes there will be an unopened one but usually they are used hardware. I would never buy one of these used. Remember that the FX chips were marketed to overclockers and hence any used ones were likely not treated kindly in their past life.

I would recommend that you just buy a new Athlon 64 4000+ from Newegg for $40. These were still some of the fastest single cores available for socket 939 and they are still available new for far less than you would pay for a used FX-55.

Thanks for the responses, does anyone know if there was ever a dual core AMD CPU made for the socket 939, or is the 4000+ and FX-55 as far as the 939 went?

Thanks,
Stan

Yea, there were/are dual cores for socket 939. The fastest dual core for socket 939 was the fx-60 if i'm not mistaken. But, you'll have to look for dual core socket 939 cpu's as they don't sell them at alot of etailers anymore. Even NewEgg doesn't have any dual core 939 cpus anymore. but like runswindows95 said, you don't need a high end cpu for a nas. hell, my nas is running off a socket A barton core athlon xp 2800+ and 1gb of dual channel ddr. it'll handle all the porn you'd wanna store on your nas

My desktop gamer runs a barton 2800 thank you very much!

Thanks for the reply, I should have mentioned before that I am looking to make the box do double duty as a NAS and DVR, that's why I was trying to see what I could cram into there as far as cpu...

My Foxconn board (NF4UK8AA-8EKRS) manual (v. 1.0) says that the FX 55 is the fastest CPU that works with that board. I'm sure it was printed before the X2's came out. Foxconn's website makes no mention of the X2 on the page for my board.

Do you know if the rule of thumb was that most any 939 board could handle a Athlon64 X2 939 chip?

Yea so does mine lol... but i can't say i'd call it a gamer. no pci-e graphics, no ddr2, no dual core... lol it just doesn't cut it anymore.

Thats my quick pick from online etailers. If you are set on getting an fx-55 that $100 tiger direct deal seems pretty good (as long as it doesn't sell out to soon)

well stan, from foxconn's website specs on your board, i don't think it will support X2's. your board has the nforce 4 chipset which i don't think supports X2's and your board only supports DDR RAM, no DDR2 support. so if i had to guess my life upon it, i'd say you won't be able to run dual core on your board.

amd had x2 in for 393 motherboard for upto 5000+ or maybe 5200+ and Fx62. although 5000+ & fx62 are not listed, i have seen many reviews.i bought ma old PC during that time so i remember them.

Just_An_En gineer makes a very good point and for now ur best bet is fx62

Wow, you guys are awesome... Thanks for all the info, so this brings me to my last question, if it was you, would you go for the $99 FX-55, or save the cash and get the $40 4000+? Is there a big performance difference between the 4000+ and the FX-55?

As far as I know most s939 boards that came out before the X2s needed at least a bios update to work with X2s. Some northbridges (like my via K8T890) never got around to supporting the X2 architecture. you would have to do some poking around some forums for your chipset to see if your motherboard supports it with a bios flash. I wanna say off the top of my head that nForce 4 motherboards supported X2s with a bios flash, but its been about a year since I have looked into it so I may be wrong

What are you upgrading from?

Just did some quick looking around and on the newegg spec sheet for you MB it lists X2 processor as supported (but not specific ones).

It's an Athlon 64 3000+, turning that into my NAS/DVR, building a new system...
