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 :lol:

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?
June 28, 2008 5:49:42 AM

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)
June 28, 2008 5:54:27 AM

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.
June 28, 2008 5:58:26 AM

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?
June 28, 2008 5:59:14 AM

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
June 28, 2008 6:00:10 AM

What are you upgrading from?

June 28, 2008 6:10:05 AM

It's an Athlon 64 3000+, turning that into my NAS/DVR, building a new system...
June 28, 2008 6:15:13 AM

skywalker9952,

Where did you see that on Newegg? I see where it says Supported CPU Athlon 64 FX / Athlon 64, is there something somewhere else that says X2?
June 28, 2008 6:19:30 AM

Second sentence of the product overview
"Foxconn's nForce4 Ultra based board brings nVIDIA quality to everyone at a value conscious price. The Socket 939 supports the Athlon 64 processor line, including the Athlon 64 X2 Dual-core processor. Up to 4GB of dual channel DDR 400 memory can be installed in the 4 DIMM sockets."

I added the bold
June 28, 2008 6:20:45 AM

I am reading some reviews on Newegg for that board and I see one guy running a 3600+X2 on it.... hmmmmm...
June 28, 2008 6:22:35 AM

Skywalker...

Thanks, I need to get the crud out of my eyes... :-) Hmmmm... now I need to find a cheap X2 processor...
June 28, 2008 6:35:14 AM

Thanks everyone for your input, checking ebay to see what is out there for X2 CPU's. As I go along I think I'm going to give more and more stuff for my NAS/DVR box to do so if I put in a beefier processor now for a few bucks more I think I'll be happier in the long run.

If anyone knows of any good sources for X2 cpu's let me know! Thanks again!
June 28, 2008 6:37:03 AM

Well thats the best I can do tonight, Your s939 question has brought up some longing to do the same thing to mine, too bad mine doesn't support X2s. Good Luck. Let us know how it works out
June 28, 2008 6:49:39 AM

Thanks Skywalker, I just sent off a message to Foxconn's tech support asking what is the fastest X2 that will run in my board... I'll post the response (If I get one). At least it looks like there are some prospects out there for X2 processors...
June 28, 2008 7:05:17 AM

I just upgraded from a s939 x2 4800+ on an nforce 4 DFI lanparty. No bios flash was required for me out of the box. Thing ran like a champ, overclocked like garbage though. Only could get a few 100mhz out of the thing (stock was 2.4)
June 28, 2008 7:21:13 AM

I've got the fx57 in my old computer which is 939 2.8 ghz still plays call of duty 4 very well

Before you go out and buy an X2, according to Foxconn's website says that your board does not support X2 processors, only the single core Athlons and Athlon FX's.

http://www.foxconnchannel.com/product/Motherboards/detail_spec.aspx?ID=en-us0000008

If you check the listing of BIOS updates it looks like support for the X2's was never added for this 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.
http://www.theinquirer.net/en/inquirer/news/2006/05/29/...

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



Unfortunately this was yet another false rumor. The faster socket 939 X2 was the 4800+ and the fastest FX processor was the FX-60.

All of the socket 939 boards only supported DDR memory. AMD had to transition to socket AM2 in order to add support for DDR2. The X2's definitely work on DDR1 as I'm running a 4200 X2 with it in my 939 rig.

Buying second hand you are best of going for socket 939 Opterons. I picked up a couple on Ebay recently at an OK price in the UK. This was for building up systems around 2 second hand DFI boards. These overclocked real nice (2.8Ghz on stock/air) with some lapping of heatsink and CPU spreader.

The socket 939 Opterons have a 1024Mb L2 cache and the x2 have 2x1024 L2 cache. They overclock well (especially the Opteron 165 X2 1.8Gz or the Opteron 144 1.8Ghz which both had a lot of headroom). The Opteron 144 can be had for about 35 GBP (new) in the UK (don't know about USA). You would need to look on Ebay for the Opteron 165, 170, etc. x2 series. Best to look for Opterons on Ebay as people will just list them by there as "Opteron+ series number"... Lots of folks don't even know what to look for (i.e. they will look for "Athlon 64 X2 socket 939") and not find/ bid for the Opterons!!

:lol:  :lol:  at all the poeple blowing cobwebs off their memories!! Has Intel been performing mind-wipes!!

I'm amazed, Foxconn sent a reply to my question this morning, they included a link to a CPU compatibility chart for my MB. It supports dual core athlon 64's up to the 4800+ and Opteron dual core up to the 180.

Thanks for everyone's help!

Look if your only going to build a network storage box from what you have, it would be insane to put more than the $40 newegg cpu into it.
You really won't be able to tell a difference between cpu's in that kind of storage environment.

Now if you want to use it for photo shop or video conversion then go for one of the opteron 175's and overclock it. the 180's are still overpriced.
Hell can't even find a good price on an opty 175, so here is the best I could find for the 180.
http://www.pricegrabber.com/user_sales_getprod.php/lot_...

Now I have a 2x4800 at the same speed and the opty 180 is a bit faster than mine so there ya go. But really for a NAS it's a waste of money.

Nah,

If the guy wants dual-core and a bit more power for other stuff so be it...

Since the socket 939 processors aren't produced anymore you need to get 2Mb cache Opterons second hand. Otherwise its a sellers market!! A single core Opteron (with 1Mb cache) is not quick so pricey to buy new (that would be fine for a good NAS box).

You can easily get a bargain on the American Ebay site. I had a quick look and I can see some good prices on the Opteron 165... It may take a week or two to get a good price (just keep bidding on them till you catch folk napping :wahoo:  )... You don't want to spend more than about 60 USD. OK so the CPUs have probably been abused a bit/ OC but they are server grade chips... You definitely want the stock heatsink as well as these are total beasts (massive finned, copper sinks with extra heatpipes) - really effective. Not like the pants coolers Intel try to palm off on punters these days (don't know 'bout AMD since they have dropped out of the race)!! Most Ebay sellers will include the stock cooler (I wouldn't trust the ones that don't...)

BTW If your are planning to OC it's definitely worth lapping the heatspreader on these old Athlon 64 CPUs as they are very concave. In otherwords raised slightly around the edge of the spreader - not the middle where the actual die is!!
