What I reviewed?

Well this eh so much of a review as it is my experience of the board and it was relatively brief. The ASRock 939Dual-VSTA Socket 939 ULi M1695 ATX AMD Motherboard retails for just under 70USD and has 2 special features that many people find very useful. It has both native PCI-E and AGP slots. Its also can upgrade to any CPU (AMD , Intel or "insert brand") via a daughter card and proprietary slot. Other than those features, this board is pretty lacking. It has 4 USB 2.0 in the back and 2 USB 2.0 headers on board (cable not included), C-media sound and the standard array of SATA, IDE and floppy connectors.

When working with this board, it was equipped with a ATI 9600PRO 256 AIW, 512 CAS 3 PC3200 RAM, a pair of Western digital 80 GB 16 MB cache 7200 rpm IDE drives, NEC 3550a DVDRW, Lite-on 40x12x48 CDRW, AMD X2 3800 with stock heat sink and CooLMax "SLI" CXI-500B ATX v2.01 500W Power Supply.



What I didn't like about this board?

The ATX power connector was only 20 Pin while most other boards have gone to the newer 24 Pin standard. This might be good if you wanted to use that PSU you bought 6 years ago but odds are that PSU eh going to cut the mustard in this case. What this means is that a 20+4 ATX connector will have to be used and the +4 part will be dangling with its only purpose in life to be unsightly. The ATX connector is to the let of the CPU and power regulators, therefore it blocks air flows and makes for and unsightly install. No gigabit LAN! The makers of this board must live in the dark ages where porn files are still less that 10KB. The layout overall seem a bit clustered. The board only supports 1 floppy. Many find this a none issue but the person who I got this board for has 2 (3 1/2" and 5 1/4"). The BIOS is lacking in the Over Clocking department. It doesn’t even give the CPU supported DDR500 option.



What I did like about this board?

The price is great. At under 70usd, this board is a steal. Why a steal? It’s stable. I have never been a big fan of AMD platform stability but this board is making me think twice. How stable is it? I ran 2 instance of Prime 95 (one on each core of an X2 3800) while looping 3Dmark2005 for about a day. Why did I do that? Because I over clocked the CPU to 2.8 GHz form 2.0 GHz. All I did was reduce the memory speed to DDR266 (the owner only had a single stick of 512 MarkVision, which wasn't the best for OCing) and reduced the multiplier to 8. If people didn't do the math, that’s a 350 cpu bus speed. I’ve not seen that on ANY boards for K8 make that bus speed, even with exotic cooling setups. What’s even more amazing is that no voltage bump was require and there was no control in the bios of the HT multiplier. Using my GSkill 2 GB Kit which I know can do CAS 2 DDR500, I managed a 356MHz fsb using CAS 3 DDR 333 setting for the memory.



Who would want this board?

If you building a new computer, definitely not you. Intel new offerings make it a much better buy and DDR2 is a little more future proof, though DDR3 is suppose to hit next year. But if you're upgrading in small steps and want to keep that video card and memory you bought 2 years ago and still get the job done, this is definitely the way. Hell if I had know this board would kick so much ass, I would have told people to buy this board over the rest of the socket 939 offerings.



What could be better?

The on board Audio is just good enough to lessen to music and to play a few games. I suppose they could have done better. The LAN port is 100MB full duplex which is kind of slow but in its defence, it had 93% sustained throughput that is the highest I've seen for any 10/100 NIC ever. The lay out off the board could have been better. The power regulators could have had some kind of heat sink as well, though didn't seem to impact the stability or overclocking ability. A PCI-E 4 slot would have be great instead of the PCI-E 1.



Conclusion.

This cheap gem has shocked the hell out of me. Its stability, OCing ability and versatility are second to none for AMD IMHO. Its short comings are pretty secondary since they apply to the none essential aspects of the board operation but the board is so dam good, it’s easy to ignore the hiccups. I'm sure anyone on a tight budget could mod this board witha little extra cooling and get even more impressive overclocking results than i did.

Its a pity ULI was bought by nvidia. But I suppose when they consistently getting higher fsbs than nf4 they had no choice. That and the fact ATI was using them.

Im personally sick of nvidia chiset issues so I'd buy this or ATI chipset if I were going the AMD way.

As for running 2 primes + 3dmark...Won't 3dmark actually suck away cpu cycles leaving little for prime to use? I could never understand running multiple stress testing tools at the same time (except dual prime). Won't it reduce the effectiveness?

100% cpu usage doesn't mean it testing everything it should. But then I guess its all a matter of what one considers "stable".

350 is very impressive. I think only DFI uber highend lanparty made close to that...340ish.

Your Gskill kicks so much ass and so does that x2. I think Im going to ask you to get me stuff with that kind of luck.

As for Intel a better deal..sure its faster but you still pay much more for it. For gaming AMD still better value.

And btw for those who don't know AsRock is a branch of Asus...a place that designs all kinds of weird sh!t.

I am a fan of Hard[OCP] style of testing so that infulences my decission to test the sability like that. The thinking is, 2 instances of prime will have both cores @ 100% but the 3dmark will cause many context switches which would stress other parts of the CPU more frequently since its an I/O bound application. This in theory should produce a more stressfully environment. In anycase, when i did have the board, it was not my intension to do a review on it. But seeing as it was so stable, i began to tinker with it (with the owner permission of course). Seeing as it wasn't my hard disks either , i didn't want to trash them with some disk benchmarks. I just wanted men to know they don't have to break their piggy bank and build a new system but instead have planned migration and have the best fo both worlds.

i would rather go with the xpress 200 chipset + either ULi or ati sb450 southbridge. like in the dfi LP rdx200... It's only $10 more and a lot more kick for your money.

Of course this ASRock will always be the board if u keeping your AGP card and upgrading that later!!! I am supposed to be doing a system for someone soon so i think I'll probably get an xpress 200 board and see how it works.

Just a minor update.
I slapped Vista 64 ultimate on this board and it works great. So great that the already impressive performance of the integrated NIC got better. With basically noting but the host Vista 64 installed and 2 GB of ram, the integrated 10/100 NIC does 99% network utilization with 3% CPU utilization off a Opteron 165 OC to 2.4GHz. Again, while not as impressive as any GB NICs, it shows how good it does what it can.
