3 out of 5 eggsit's all about the CPU stepping, it seems - make sure it's a C2

Pros: With 6 total sata ports, am3 cpu support, dual gigabit nic's, and easy onboard video for when you need it, this is a pretty perfect board for a d.i.y. storage server running either ubuntu/centos linux or possibly freebsd/freenas if you're into zfs/raid-z over traditional raid-5. The pci slot can be used for a variety of low-end secondary connections or a budget alternate graphics solution. There's an onboard com header that makes for a positive surprise after not being mentioned in the specs. Can easily boot 95w-tdp cpu's, despite what the specs say.

Cons: Huge trouble getting this thing to post consistently (and then later, at all) with an athlon ii x2 260 for my first cpu attempt. Knew that the black socket strips issue didn't apply to me, so started doing some other research and came across a random blog page suggesting that the board's problems could be isolated down to the cpu stepping and that it would only properly work with C2 processors. Threw in a phenom ii x3 720be I took out of another build to give the theory a try and all post/boot problems instantly vanished - a success in the end, but still not acceptable to have lost weeks over the issue after not seeing a single mention of the limitation anywhere in the specs or manual. There are plenty of other issues, too, though - incorrect clear cmos header labeling in the manual, board won't boot linux when you try to populate the 2nd (underside) ram slot due to a kernel panic, and no cpu/core voltage control option in the bios for undervolting / minimizing power draw.

Other Thoughts: I know that this board is probably dead and gone, but just wanted to throw the stepping info up there for anybody else that might google the model # for suggestions or troubleshooting.

5 out of 5 eggsGreat little board

Pros: Used this with an old athlon x2 i had to build a rsystem for my friends parents, however i didnt notice it uses laptop memory...... Other then having to buy some ram it was awesome booted right up and did what it was supposed to do!

Cons: Make sure you buy ( or read because i was stupid and didnt) that ull need so dimms for this board

2 out of 5 eggsso so only

Pros: small (m-itx), 2 network interfaces (could be used for nice router/firewall). older platform (lower and lower price) so all required build parts may be laying around

Cons: the biggest problem for me is unreliable POST - sometimes I have to press reset multiple times before it'll start OS (both cold start or OS restart) - this is major issue if you wanted always on system that would have "restart after power failure" option turned on (this could be setup specific issue but I'd doubt this). Did not observed stability issues once started but with only dedicated RAM (128MB) used for video frame buffer you get artifact in videos (youtube, vimeo, media center performance). in general video performance is not that great - aging video chip. also power consumption for the whole platform is not that great (have athlon II at 2.9) and north/south bridge heatsink gets very hot. supplied cpu cooler is sufficient and not overly noisy but amd cooler does better job. extra fan for chipsets may be needed (depending on the case). PCI and not a PCIe slot.

Other Thoughts: got this thing when the price dropped down to the level that allowed for experimenting - had spare 2GB RAM, old sff case (some dremel action helped fit it in), drives etc. because of the startup issue it's hard to recommend it (can't even give it away because for non-geeks this could be too much to handle). also power usage and video performance may be sub-par for htpc.

4 out of 5 eggsWatch every miniscule detail

Pros: Motherboard is stable and fast once configured correctly. Need all 4 gig of RAM, 1 gig reserved for video.
Works good with Windows 7. Intel 320 120 gig SSD with 1TB HD secondary, really super fast.

Cons: 1) CPU heatsink too small. Customized aftermarket cooler base with dremel tool- worked well after. 2) I built this system to utilize old hardware incl. CPU, the CPU has to match the part number EXACTLY, constant blue screens of death until more $ 3) Manual is wrong bios setting caused 3 hours hardship trying to figure out no video until I discovered the jumper move 4) manual wrong orientation jumper for 5 volt rear USB terminator 5) tech support for the video took 3 working days to reply to Email and NEVER returned my call. Newegg can't find help- on your own 6) no HD header, need 1 built into case 7) AMD bios acronyms are too much even for this expert. There is NO online help for this stuff. If you can't put two and two together- call a friend, 2 heads better than one

Other Thoughts: Some reviews indicate no video, I think they were confused llike I was about the bios battery/reset jumper. Other reviewers indicate black strips but don't say where- they are over the processor socket (Jetway finally sent a photo). Mine did not have them. AMD after 20 years building PCs, I hate it that I chose an AMD again and ended up not using anything existing but the case and CDR, they never cooporate first time and unstable- have to fidgit for hours and no customer support to get it to work well. If you have the patience, this time worked well after many hours and sweating it out, they will eventually do what you want, watch the details. I gave it 4 stars because it does actually work, but at what cost?

5 out of 5 eggsWorks perfect

Pros: Works perfect with a 2.0GHz X4 65W Phenom. With standard heat sink idles at 30-32°C Using 32Gb SSD as boot system and 1.5Tb drive for all my movies inHTPC setup. works fine on Windows XP and 2Gb Corsair RAM. Boots in 15 seconds.

Cons: Little tight on coonnecting all internal USB headers

Other Thoughts: Don't know about all these DOA complaints-I would think it unlikely that you'd get 3 dead boards in a row like some people claimed.

1 out of 5 eggsDOA

Pros: Nice Specs. AM2+ CPU support (not Atom!). 2 Gigabit Network ports w/ 2 external eSata all in small ITX form. Seems like quality build.

Cons: Okay first off, before you read DOA and think to yourself: "This guy probably doesn't know s*** about how to set up a system" (that's what I usually think when I read DOA reviews :P), I would like to say in my defense that Ive tested this thing out with (luckily I always have spare parts laying around):

4 different sticks of SO-DIMM DDR2 modules (1GB/2GB, Hynix, Corsair, G-Skill)

- 3 differing CPUS: Athlon 4850e, Sempron 1640LE, Athlon II 250

- 3 Power supplies (Antec SL220W, OCZ 650 Modstream and some noname small formfactor).

All combinations of the above and the P.O.S*. WOULD NOT POST (no beeps.. no video - fans spin but nothing). I have built around 10-15 different systems as a hobbyist (starting at my first 286 clone) for myself and NEVER have I had a NO-POST out of the box. Is this Jetway's poor quality control or a resold NewEgg RMA? I'm not sure, but after a 2 week wait I'm a little let down to say the least (this is my first DOA from NewEgg).

Other Thoughts: Also I never recieved the heatsink that the NewEgg image says comes in the package... This leads me to believe that this particular Mobo is a resold RMA

4 out of 5 eggsa few quirks, but definitely satisfied

Pros: High quality - solid caps. Very capable for its size/price. Perfect for HTPC. Biggest plus? It's not an atom.

Cons: The capability of the board to handle desktop rated processors (65W) combined with the lack of 45W or less dual core chips means you have to plan carefully if you want to use a small case. The included heatsink is completely inadequate for such a chip, yet is a requirement in order to fit into most cases which put the power supply above.

I purchased Rev. 1 of the hardware, which uses an AwardBios (current ver uses AMI) - by default, Cool and Quiet is disabled, which further aggravates the aforementioned problem.

As other reviews mention, there are these tiny black strips on two sides of the socket. I RMAd my first board before noticing the review, and the second suffered the same no boot issue until i removed these. Thanks for mentioning in the manual, Jetway - great way to waste $ on shipping.

Lastly, once I enable AHCI, I am no longer able to reenter the BIOS - in order to tweak anything else, I have to use the reset jumper.

Other Thoughts: Tips I think others might find useful:

- drop the VDimm power down to 1.85! No need to have it so high.

- HDMI audio disabled by default.

- SFAN smart mode is disabled by default but makes a vast improvement in noise.

Really a sweet board, and I'm really looking foward to my lian-li q07 to put it in.

4 out of 5 eggsNice

Pros: Very small board, maxes at 2 x 2gb sticks of RAM. Supports pin connecting wifi adapter (see cons) As many connections as you would want... perfect for tiny htpc projects

Cons: Called Tech Support for Jetway because I couldn't get video on startup. Turns out there are "sticker" strips on the chipset mount for the CPU. They are rigid enough they feel like plastic even after they are removed. I thought they were part of the component themselves. I'm new at this, having only built one PC before this, but I think this might be the problem for some of the other reviewers who cannot get video to load. Hard to believe Newegg would send as many as three DOA's in a row to some of these guys. Support also mentioned that this motherboard only supports up to a 65W CPU, so be careful of heat on anything bigger. Also, it supports a special on board pin connection for a wifi adapter called a "wifi diagram", however, good luck finding one. Newegg is the only place I can even find it and it's not in stock.

Other Thoughts: I put this into an case mod I made out of a clock my brother made in woodshop about 20 years ago. I got a 500gb WD HDD, 220 W PSU, this motherboard, 4 gb ddr2 800 ram into 13x10x2.5 area. I don't dare do any real computing on it because I've got a 95W Phenom CPU, but works great for streaming Blu-Rays and DVD's from my first build I keep in a separate room on the network.

2 out of 5 eggsMeh

Pros: * Very Small Form Factor
* Supports recent, powerful AMD CPU's

Cons: * Using Crucial DDR2 1GB sticks, I cannot use more than 1GB of memory. Inserting a second 1GB stick into the bottom slot causes and endless loop of crash and reboot.
* Fan is unnecessarily loud; a coper heatsink and slower fan would have increased the cost slightly but dropped the noise considerably. It also would have helped if they had polished the bottom of the heatsink or at least didn't leave it untreated.

Other Thoughts: I bought 5 of these with high hopes. They meet my requirements, but I don't require more than 1GB of RAM for my Linux based systems. Running Vista or 7 with more than a light load is ill advised with less than 2GB RAM. RedHat based distros may have some trouble configuring some hardware especially the NIC; Ubuntu 9.10 32-bit & 64-bit work perfectly.
I'd check memory compatibility on JetWay's site, but the board doesn't come up in a search...

5 out of 5 eggsExcellent HTPC Motherboard

Pros: Lots if features, Onboard HDMI, Small - fits ITX cases. Running Windows 7 x64 - boots quick. Easily upgrade cpu - supports amd quad core. Bought 2 of these - one open box and one new. I love the heatsink/fan that came with the new one - gives more room for air flow that the stock heatsink/fan that came with the cpu.

Cons: Had to flash bios in order to in stall Win 7. Need to install only one stick of memory before installation, then install 2nd stick after installing Windows. Motherboard runs considerably warmer than standard motherboards. Make sure you have good air flow through your case. When flashing the bios, its probably best to just have one stick of memory installed for the reboot afterward.

Other Thoughts: I have read a couple of the reviews that said that they didn't have any video on boot. I also had the same problem, but by removing one stick of memory (had 2 2gb sticks installed), everything worked fine. One the bios had booted once, then the other stick of memory could be installed after shutting down and worked fine. Installed Fedora 12 on one system - everything worked perfectly. onsidering addng a small case fan to help with air flow - cpu not getting too hot, but certainly can't hurt.
