Problems even after a rma


After returning the first board and getting a rma it took 3 weeks to get another board from tyan. my suspicion is that tyan send me a board that someone else has rma'd and they had (fixed) unfortunately they didn't test fully to figure out that the...

2nd motherboard seems really stable ; accepts my areca raid controller w/o issue ; all features basically work

First board DOA ; no pci-e 1x slots besides the 2 16x sli connectors ; cpu placement on motherboard makes cable runs tight in a normal atx case ; after rma my rear sound connectors didn't work, audio does work through front audio connectors though ;...

Last Best Option for 939


I bought this mobo because N-Force 3 250GB Chipset doesn't support Dual core Procs along with AGP for Vista, and I'm in defiance of spending at least a grand for a full system upgrade to run vista Opteron 180, 2GB Corsair XMS DDR 400, ATI HD2600 Pro,...

It is a excellent quality alternative to what is left to support the AMD 939 Socket. It is designed primarily as a workstation/server mobo so it will support the use of ECC RAM. Has everything: PCI-E x16, PCI-E x1, PCI, USB, FireWire...the list goes on...

I had to disable the AC-97 Audio in the bios because it was causing the blue screen of death in vista. (more likely than not I'm assuming the vista drivers)

Solid, Fast, No extra shi#


Took 5 days to get to me. Longest ever for a newegg order.Not bad really.

Just what the doctor ordered for a guy that doesn't O.C. But wants a fast PC

No French maid

Overall Great


I'm going to update the BIOS (3.02 to 3.04) to try and get the 1TB Seagate ES to work.

I have used this motherboard for a year running 24/7 with a dual core AMD Opteron 170, four 750GB SATA II drives (non-RAID), and constant use of both ethernet ports, without a problem

I just tried replacing one 750GB drive with a 1TB drive and now the system doesn't boot (POST). Tyan says there is a 2TB limit, which I have yet to see and maybe only applies to RAID

Consumer review by: Peter (

Very disappointed


Changed 2 different power supplies, 3 types of memory, even 2 different CPUs in order to isolate the problem... Must be a defective motherboard. Nothing fancy in the PC configuration: just 1 IDE and 2 SATA disks, no add-on cards, onboard graphics card...

Nice layout. No useless components as for a server motherboard

Hangs/reboots occasionally, which is not acceptable for a server

Great Budget Board


It's a budget board. Aside from any manufacturing defects, it's hard to complain about missing features. Save your pennies and purchase one that has the features your looking for.

While it's not loaded with features, it's stability paired with an opty 170 and a couple gigs of corsair 3200 is outstanding. No boot or install issues

None thus far

Great 939 Board


Easy Config, it auto senses CPU and voltage.

No SLI support.
