Pros: When it works, it works. It has a somewhat unusual slot configuration that I needed for a build out.

Cons: I purchased a total of six of these motherboards. Out of the six, three were defective. One had a short on a PCI slot that fried an add-in board, one simply would not ever get past the BIOS screen, and one had a short on the IEI controller that produced a visible spark. I have built hundreds of systems and never had this high of a failure rate on a board. What is worse is that Tyan customer service has been completely unresponsive. I submitted the RMA online, followed up with several phone calls, re-submitted the RMA's, but all I have gotten are form e-mails and stock responses to my calls. At no point has anyone at Tyan actually offered to repair or replace my motherboards. I got about 10 minutes of troubleshooting and then was referred to Tyan's online RMA form. I have been working on this issue for a month now. I am now going to attempt to work with my credit card company to see if they will approve a chargeback.

Great Board. Be prepared to update bios.

Pros: Great board. Works with 6 core istanbul(s) with a bios upgrade. Good number of PCIe and PCIx slots to work with. EATX form factor is a bit big, but that also helps with giving cables and jumpers more room to work with.

The board comes with 6 SATAII ports and plenty of USB/firewire ports for expansion. Great for a workstation. I'm using it for my all-in-one for my photography, video, and virtual machines.

Be sure to get an EPS 12V compliant power supply with the 24+8+4 power connectors. It's a hard requirement.

Boots Opensolaris X86 just fine. All hardware is detected right off the bad. Kudos to Tyan for producing a great board. (aside from bios issue)

Cons: Some of the indicator light jumpers are butted right up against the edge of the board, where it would run into the hard drive cages and the like. Kind of annoying. Also, the board has NO speaker jumper, no piezo beeper, and no LCD/LED indicator for port x80 status codes.

And the one that had me placing an overnight order was the fact that the bios on the board doesn't support 6-core processors out of the box. You need to flash it to the 4.0 firmware. If you already had a supported opteron lying around, you're all set. If you don't you're ordering a replacement bios out of pocket.

Overall Review: I bought this board to build out a 12 cpu core monster, like the other poster. Likewise, I went with 2 6 core istanbul's at 2.2Ghz. And just like the other poster, I ran into the bios problem. An overnight order from biosman.com got me a replacement bios chip (v4.0) that worked the first time. Kudos to biosman.com for getting it to me so quickly.

Excellent Board

Pros: Board performs perfectly as intended, both sockets populated with amd opteron 2427s 6 core and all ram slots populated for maximum 32gb ram. 40+ hours burn in testing no crash at 60-90% processor utilization.

12 cores of 2.2ghz processing power and 32ghz of ddr2 667mhz ram. Its a monster.

Cons: If your utilizing the new istanbul series 6 core processors you will need to verify you have version 4 of the bios if not you will have to go through a 3rd party bios chip replacement site as i had to. System did not post until we ordered a v4 bios chip from biosman which immediately booted the system with 0 problems.

Regardless of the cons and the notes i put in other thoughts the board works excellently. Boots quickly and has everything you could want for a general workhorse server.

Overall Review: First board i got had a truly ratty looking box and the serial/spdif ports were nearly torn off the board. Several pressure points were noted on the boards static bag via large indentations in the plastic over capacitors indicating it had been either stacked under large heavy boxes or the like. I took one egg off the rating for that sad quality control at the warehouse sending such a horrible looking box. I never installed that board requesting an immediatly replacement which newegg promptly sent. The board packaging on the second one was in excellent shape, no pressure points. I question how tyan packs their products as again in this board the serial port was slightly lifted off the board but was easily pushed back in place. The spdif port was lifted as well and the plastic housing was cracked and split, it was easy enough to push back down as well with no worries as i will not be utilizing these ports and the damage wasn't severe enough to even worry me, but i did take a second egg.

watch psu connections

Pros: I've built 2 of these now, mb's not purchased from newegg but most of the other parts were. One for my parents, and a sister who does a lot of graphics. Excellent for this, very fast and has been extremely solid once I got them to post. I used to use mostly ASUS but this board has me very happy with TYAN.

Cons: Watch the video card, and make sure you have plenty of power. Both boards were touchy starting and posting the first time, very important that the 24 pin is solidly connected, and if won't post with newer cards make sure you update the Bios

Overall Review: using a pci-e 2.0 video gave me headaches with original bios.

Solid Workstation/Server Platform

Pros: Flexible I/O, Chipset bandwidth, and extensive Processor Support. Many undocumented cooler options

Cons: Many undocumented cooler options. Power Connector layout.

Overall Review: I've built at least 5 of these, as workstations and servers. They require careful integration but are worth the effort. With either a PCI-E or PCI-X dedicated raid controller they are real workhorses.

Good Board

Pros: Has almost all the features that I want. Silent. Good included audio hardware.

Cons: Tyan needs to invest more in its website. Site is slow and/or unavailable sometimes(last two days). No power-on from keyboard option in BIOS ( my computer case is outside my room door, to reduce noise ) and I got used to my older ASUS system powering on my machine by tapping the keyboard spacebar. No included hardware monitor software something like ASUS PC Probe ( hardware monitor screen is available in BIOS setup, though )

Overall Review: Initially got no video using new PCI-E 2.0 video card, used an older PCI video card and I was able to post. Flashed bios from 2.04 to the latest 3.00 (for Shanghai) using Dr-DOS and bootable DVD created in Nero 6. Now all is well. Would be helpful if Tyan included info on their website about compatible HSF. I did some research on the web and installed Zalman cnps7000 cu (overkill?) but had to dremel out the top of the Tyan HSF mounting brackets to reduce bracket heights because there was vertical freeplay in the HSF/cpu contact and board was shutting the system down after 30 seconds (to protect the cpus) when case was upright. Now both cpus idle around 22 c. I have no use for the PCI-X slots, but then the board has 5 PCI-E slots and that's plenty.

Ehh

Pros: Tyan name.

Cons: Bad layout. I also was unable to get the motherboard to boot from a third party raid card, but I haven't gotten mine to work yet...

Support is horrible. I bought two, had to RMA one, and it was like putting teeth to get them to replace it. I asked them for help on my raid card problem and they basically ignored me. I may be looking at other brands in the future.

Overall Review: Don't buy this one

Pros: works as specified. Backplates are already attached to the m/b - no need to purchase separate one for CPU fan mounting. Rear panel fitting/covering USB, Ethernet, etc. ports is included.

Cons: no on-board SAS.

Overall Review: Tyan specifies max RAM as 32 MB, not 64. Make sure to get registered, not buffered memory and a PSU with all three power feeds (as per SSI spec).
