5 out of 5 eggsAWESOME MOBO No Ram Probs please Read

Pros: Will do the same job for you and in some cases even better than the newer i- series mobo's at a lot less cost

Cons: None

Other Thoughts: This MOBO Rocks and the Skull Logo printed on the MOBO & bridge Cap is a great affect ... I SetUp using out of box Bios & no problems with this board at all.No Ram trouble at all if you first read on how the board ram set-up works - Use Either 4 sticks DDR3 1gig ea. or 4 sticks DDR3 2gig.ea. I stacked it with 4 sticks DDR3 2gig each stick for a total of 8gig. of Ram ... It is Micro Center 1333mhz PC3-10666 High Perf Duel Ch. DDR3 RAM & its there house brand so cost me only $80 total & this house High Perf ram is made for them by ABIT so its great ram. To Order Online Use MICRO CENTER Site Search. THE PART NUMBER FOR THE RAM IS - 168237 - ... I'm running a Intel Core 2 Quad-core Q9650 with a EVGA GeForce 550 tsi Graphics Card, with a Ultra LSI 750 Watt Power Supply, & well by now you all know what ram i'm running ROFL ... Remember some say this board takes 16 Gig of Ram Max and That Is A Lie as IT ONLY TAKES 8 GIG OF RAM MAX which even as of this date of posting is still way way way more than enough in use with still some left free to spare & I my friends do quite a bit of online gaming and video editing and have never so far run into a problem & I mean not even a little bit. I keep up with friends using the newer i-3 i-5 chipped boards easily& in some cases totally out preform them . In Operation under heavy use for over 6 months & no problems what so ever. This MOBO will do what you need it to do and more. Well hope this helped you all somewhat ... TY for reading & by all means Trust this MOBO you will love it . I sure know I do :)

5 out of 5 eggsCluster Capable

Pros: This review is mainly for anybody looking for information on this board that is new material:

This board DOES support Core2Quad Q6600 no problems
This board DOES support GTX 400-GTX600 graphics cards
This board is picky on RAM, but the CRUCIAL sticks recommended on Intel's ARK are easy to find and dirt cheap to pull 8GB worth, and it's well worth getting the full 8GB
This board is FULLY supported on Linux and Windows

Cons: The SATA ports in the quad-group get blocked by a second graphics card. (Namely a GTX 480)
First PCI-E x1 slot does get blocked by the first graphics card, but if you need more than the one reachable x1 slot, get a different board

Other Thoughts: I have 12 of these in a mini personal cluster all running with Core2Quad Q6600s, 8GB Crucial DDR3 RAM, 2 GTX 650 Ti BOOST cards for the master node, 2 GTX 480 graphics cards for the compute nodes, and Cougar 760w PSUs. This board has a very low failure rate and has worked wonders for me for my research. Highly recommended for someone on a budget! (Especially considering how cheap these parts are now. $100 for this board, a Q6600, and 8GB RAM!)

1 out of 5 eggsDOA

Pros: Can't think of any.

Cons: Was DOA. NewEgg return policy was excellent as always and they quickly got me a turn around on a new board. No problems with the new board since.

5 out of 5 eggsHad this board almost 4 years

Pros: Had it about 4 years no problems with it, oc my q8400 about a year ago to 3.2 and ram timings from 9-9-9-24 to 7-7-7-20.

Cons: When I got my second 5770 had to bios update to get the white noise to stop. Not really a con since bios updates are a good idea at times.

Other Thoughts: I have never really had any problems with this board maybe I got a lucky board. OC stable crossfire no probs. I have 8gb or gskill ripjaws in it didn't bother to look at the compatible ram list. In case you get the board and max out ram get 4x2 sticks wont read 2x4 as per the instructions. The board is a little weird when you oc, if you oc you will see when you get to it. Still gets the job done though.

4 out of 5 eggsGreat board, once you get memory that works with it and update the BIOS

Pros: Once you get past the memory issues (see other thoughts for my solution) it's a fantastic board. Boots quickly, good readings all across the board, allows me to overclock without stability problems via an unlocked multiplier (haven't tried FSB overclocking). Paired with a EVGA GeForce GTX 550 Ti FPB 1024 MB GDDR5 PCI Express 2.0 2DVI/Mini-HDMI SLI Ready Graphics Card, 01G-P3-1556-KR and I'm having excellent performance across the board.

Understand, this board, is a very good board. You just have to be patient enough to get past the memory issues.

Cons: Very picky when it comes to memory, intel has stopped issuing updates for the board and no longer offers technical support, other than warranty and RMAs.

Other Thoughts: Alright, so all the reviews about this board being particular about the memory it will function with are indeed true. I had to order to RAM off of amazin that was on the approved list that intel has up on its website. The first sticks I ordered from Newegg kept giving 3 beeps on startup which with this board signifies bad or incompatible sticks. The sticks I initially ordered that didn't work were G.SKILL Ripjaws Series 8GB 240-Pin DDR3 SDRAM DDR3 1333 Desktop Memory Model F3-10666CL7D-8GBRH. The stick I ordered off of amazin that DID work WITHOUT the BIOS update (I.E. worked with the stock BIOS) was Kingston ValueRAM 1GB 1066MHz DDR3 Non-ECC CL7 DIMM Desktop Memory. After I got this stick, it powered on just fine, no BSOD, no problems. I got the BIOS updated via an ISO file and a flash cd-rom, and the original sticks I bought still didn't work. Tried these, worked and are working flawlessly; G.SKILL Ripjaws X (4 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Model F3-10666CL7Q-8GBXH

1 out of 5 eggsThrow It Out a Window!!!

Pros: It looked promising, with it's awesome specs and 8GB of RAM capability.

Cons: It was extremely picky with RAM. It only worked with ones that were labeled on the Intel website. It DOES NOT HAVE ON-BOARD GRAPHICS which may not be a problem, but this motherboard is also extremely picky with which video cards will work (avoid everything in the GeForce 400 series)

Other Thoughts: For as awesome as this motherboard could have been, it failed miserably when it came to being compatible with the most generic of hardware. The motherboard drivers kept failing at installation as well as any connection with the video card. I bought three different RAM brands to get the thing to even turn on without the post beeps. Just avoid this motherboard at all costs.

1 out of 5 eggsWaste of time.

Pros: Nearly the only only Crossfire motherboard for LGA 775 sold in 2012.

1st ram slot is clear with a 212+

Cons: 8GB of RAM is rare. Most manufacturers have upped their RAM densities. Multiple 8GB kits, I was met with a no POST 3 beep.

S3 sleep is not working in Windows 7 64bit. Intel says use S1. S1 sleep does not save much power.

NIC drivers broke internet connectivity.

Not particularly stable when overclocking my X6850 compared to my other P45 and P43 Motherboards, even though it is marketed as the "extreme" board for the "extreme" CPUs.

Other Thoughts: PCI-e layout makes it difficult for 2 GPUs and a 1X card. (blocks GPU Fan on XFX 6950)

Being that this board will not work as advertised, I can not recommend it.

Search for RAM/Sleep issues on this board. The results are plentiful.

3 out of 5 eggsWhoops!

Pros: Intel 3yr warranty. Lots of goodies, great price for what was an $$$ board. Needed a new board for my Core Duo E8400 and it fit the ticket along with the cheaper newer DDR3 RAM.

Cons: DOA, Newegg did not allow return so now I have to hassle with an Intel RMA.

Other Thoughts: I bought the last one Newegg had apparently, I beleive this board may have been a refurb given the marks on the CPU bracket and "Windex" like smell upon opening. I put in 3 different brands of RAM that meet board specification only to have it give me the 3 BIOS beeps. Not pleased to say the least... 3 Eggs only because I know Intel will warranty it. (hopefully without much fuss!)

4 out of 5 eggsCheck your processor FSB before you purchase!

Pros: P45 Chipset
Intel ICH10R Soutbridge
ATX Form Factor (Full Size Motherboard)
2 PCI-E Slots
5 SATA ports

Cons: 1600/1333 FSB Speed (DOES NOT SUPPORT 1066 FSB, YOUR Q6600 or any 1066 FSB processor WILL NOT WORK)

RAM Compatibility Issues (must update your Bios to get some brands of RAM working, ships with old bios)

No PS/2 Ports for your old mouse and keyboards.

No IDE ports for your old DVD/CD Roms or old hard drives.

Doesn't really come with a manual, just a quick reference guide that folds out. Gotta goto the intel website to find the PDF if you want any special information.

Other Thoughts: Make sure you check to see if your processor is compatible. This motherboard only supports processors with 1333 FSB or 1600 FSB speeds. Do not make the mistake of trying to get this to run an older Core 2 Duo or Core 2 Quad processor.

Everything on this motherboard is what I was looking for.

5 out of 5 eggsExcellent board, still going strong

Pros: I am going to list out the pros of the board that are not in the specs, relative to what I am using it for:
At the moment, I have had this board for over 2 years in my system. Started with a E8400 Core 2 Duo and moved to a Q9400 Core 2 Quad. Overclocked the CPU from 2.66GHz to 3.0GHz via the Intel Desktop Manager.
It is in a Cooler Master HAF 932 Case, with a Zalman CPU cooler, an XFX 5750 1GB GDDR5 GPU, 6GB of Kingston KVR memory.
Whats nice is I have kept this board up to date with todays technology. I have a PCIex1 Card for the front USB 3.0 ports on the case which work wonderfully. The system runs VERY VERY stable. I cannot remember the last BSOD I got. Take that back, it was when I had some bad OCZ memory that needed to be returned. I am running Windows 7 64 Bit which it runs beautifully. I would buy another one of these boards just to have a spare incase this board were to fail after the warranty. So far, it has done everything I have expected and more.

Cons: As far as cons go...
It's not a 1155 socket? Not SATA III? It doesn't make me coffee in the morning? This board was part of my first system build, and I still use this system to date. I built it back in February of either 09 or 10. This is a very very stable board. People who have complained about it I am sure are not doing something right or have the worst luck of all. The reason I choose Intel is the company I work for has an Intel partnership. Should the board fail under warranty, BAM, new motherboard next business day courtesy of Intel, no questions asked. I'm sorry, can't beat that. I love @SUS boards, they have come a long way, but until my company gets an @SUS partnership like the one they have with Intel, Intels will have a firm place in my heart.

Other Thoughts: I think most people that have a bad experience with a system build have some other things happen as well. They lie about their tech level, cause let's face it, a real high level tech wouldn't complain in reviews about it, they would take that effort toward figuring out the issue that they shouldn't have run into in the first place if they did their research in the first place. A lot of people just throw a bunch of stuff in the cart. The pick one or two really good items and a bunch of cheap stuff to go with it and when surprise surprise the system doesnt boot, the blame the most expensive components first.
