ASRock Innovates Socket 939 Motherboard with AMD 785G Chipset

This creation by ASRock is bound to surprise you. The motherboard specialist used a present-generation AMD 785G + SB710 chipset to drive a socket 939 motherboard, called the ASRock 939A785GMH128M. That's right, socket 939, supporting some of the oldest processors in the Athlon 64 and Sempron 64 series. The socket 939 CPU is powered by a 5-phase power circuit. It is wired to four DDR memory slots, supporting dual-channel DDR memory at speeds of up to DDR-400 MHz.

The AMD 785G chipset packs an ATI Radeon HD 4200 class integrated graphics processor with 128 MB SidePort memory, while the SB710 southbridge provides 5 internal SATA 3 Gb/s ports, and one eSATA port. The expansion slots on this micro-ATX motherboard include one PCI-Express 2.0 x16, one PCI-E x1, and two PCI slots. The IGP connects to its displays using DVI-D, HDMI, and D-Sub. 8-channel audio, and gigabit Ethernet make for the rest of it. There is no word on the availability or pricing as yet.

LAN_deRf_HAMy 939 Opty was 100 MHz faster clock for clock than first gen AM2 procs... and my value select ddr1 scored 5.9 in vista. When I switched from that system to a 3.5 GHz core 2 there was no performance increase noticeable in games, particularly in gpu dependent games like crysis. So for people with the right processor oc'd far enough 939 should still provide relevant performance.
yup agreed.. playing game like crysis will need good GPU.. my previous system almost scored 5.9 in vista, except my cpu scored 5.5 (bcoz it is dual core) which is for me much better than the other newer processor.

This is very, very interesting. I have two friends running S939 systems and one of the systems is being kept alive only capacitor transplant. This might be exactly what the doctor ordered !

Great idea ! :toast:

I still ahve a Xfire capable 939 board downstairs i bought off fleabay for the other thigns that came with it. Sold my 2Gb 1t kot to work for $40 OCZ Platinum 400's with micron chips.......

While this does look like a cool board for those retro s939 processors (own an X2 4200+ 90nm Toledo myself), there are some drawbacks. The DDR-400, while having low latency, is rather slow for advanced IGP (although the IGP does have that 32bit Sideport memory IC). Also, 939s are Hypertransport 1.0 compliant. This is also a bottleneck for the IGP. I'm pretty sure that if you use an old AM2 HT 1.0 on a 780G board, the HD decoding ability (UVD) of the 780G is disabled, due to the slower, older revision HT. It might be the same case for this board, unless the Sideport RAM magically fixes the inherent bandwidth issues. Just my $0.02.

Now that's done it! I've been looking for a 939 board to turn my 4400+ and 4gb ddr into a small home server/HTPC and this is perfect!

No need for a dicrete graphics card so i can make this silent with low heat output, and stick in a few TB of HDD space to backup my main rig :D

.... wtf!?!?


i'm sure a million small businesses started crying tears of joy, but otherwise... no deal.


DDR1 ram is so expensive, finding 1-2GB of ram for that alone would make it cost more than a DDR2 variant of the board and ram combined.

Not if you already have it laying around from an old build. I think that is what this is targeted towards.

ASRock has always tried to fill small niches with some of their products. They have many boards mixing both old and new parts to try to help a builder be able to recycle parts, but also move forward somewhat.

My 4200+ and my 3200+ are doing their little dance of joy. :laugh:

devguyThose of you with the infamous Opteron 1xx serious chips, this is your dream come true!
crap and i sold my 4GB worth of Mushkin Redline DDR500's four months ago! on the upside i still have my 165 that got up to 2.7GHz on my DFI NF4 SLI-DR Expert that died on me earlier this year. this just answered the call for the upcoming bedroom system!

i won't change also my 939 rig ;the point is i can play all new titles;i'll change only when something die or i won't have enough fps.

just wonder if this board can be used in crossfire x...

it can, following the same rules as all over 780/785G boards.
(which means only with a select few, entry level cards)

words cannot simply express how fucking awesome this phenominal item of WIN that ASROCK has pulled out from the depths of hell.

this is a great idea, Kudos to ASROCK.

I still got 3 939 procs lying around & with THIS i can get the running again & with PCI-E graphics too!!!

boy Im gonna have a field day getting my 3000+ & Fx55 back up & running. not to mention being about to give my working X2 3800+ (@2.66Ghz) rig a facelift.

but despite all that, Im guessing the 939 cpus will serverely bottleneck higher end PCI-E graphics cards

----------------------

On that note - its a shame DDR400 (PC3200) is so expensive now..... its around £60-80 here in the UK for a 2x1Gb Corsair/OCZ value ram kits.... *sigh*

My 2x2Gb DDR2 1600's didnt even cost me £40......

(I use to own a set of Elixer value ram that clocked to 480Mhz on 3-3-3-8 for around £20 a 1Gb stick)
