Pentium Guy, thanks for the continued effort. I only wish I'd read your guide before building my rig... I might have made a different choice.
My .02 regarding motherboard choice comes from experience building my second rig. After some on-line research, I picked the following components:
Athlon 64 4000+ San Diego
Zalman CNPS7000B CPU cooler & fan
ASUS A8N-SLI Deluxe
Corsair Twin x 2048-3200c2 (2 GB total in two sticks)
OCZ600ADJ SLI PSU (600 watts)
2 x BFG 6800GT OC (256 MB each)
Hitachi 160 GB SATA II HD
Win XP Pro
Lian-Li PC-V1000 case
I went with the A8N-SLI Deluxe rather than the Premium because I had read that the passive cooling pipes didn't work correctly with an inverted case (like my Lian-Li.) After assembly I got it to POST on the first try (yeah!), and all went well with 66.93 graphics drivers. 7X.XX drivers all caused a hard crash and auto reboot without graphics (black screen, but normal boot noises.) Cycling the power restored graphics. The only game I was playing at the time was Pacific Fighters, which had other problems with the 7X.XX drivers anyway, so I just reinstalled the 66.93's and pressed on...
When the 81.85 drivers came out, they solved the game problems, so I tried those. Now I was getting the hard crash both in game and from the desktop. Much troubleshooting later (going from dual card to single card, swapping the BFG's, power connections, drivers, etc.) showed the second PCIe graphics slot on the ASUS was dead. Among all this flailing I also discovered that the ASUS utility for updating the BIOS was just as useless as I had found it several years ago during my first build. All of my attempts to update the BIOS with the utility were met with "unable to connect", "too many users" or "no appropriate BIOS found on this server". After a call to ASUS tech support and customer support, I RMA'ed the board. The folks I talked to both times were great.
Talking to folks at TigerDirect (we have a retail outlet here in the Chicago area) they recommended either MSI or Abit to replace the ASUS mobo. I've had good luck with MSI in the past (I went with one of their socket A boards on my first build, which is still running strong as my wife's computer) but hadn't ordered one initially because I'd read in a NewEgg review that their mobo BIOS couldn't be flashed to support X2 processors (I might want to upgrade later.) Later reseach showed this to be wrong, or at least corrected in later releases of the board. The good news was that the MSI K8N Neo4 Platinum SLI POST'ed too, and the MSI update utility works very well. I was still getting occasional hard crashes though. Then the PSU died...
At this point I gave up, dropped back 10 and punted to a local computer shop. Talking to the tech there, he confirmed that the PSU was dead, and that he'd read an article noting problems with PSU's powering SLI'ed cards with a Y connector (two molex connectors Y'ed into one PCIe graphics power connector.) They pulled the dead PSU, and I RMA'ed it, which is where I now sit. I don't know if the PSU was the underlying cause of my crashes, or if the ASUS PCIe slot failed on its own, but right now I'm hoping the problem was a slowly dying PSU, which cascaded problems to the mobo.
Lessons learned:
- Trouble shooting new build systems is a pain, since all the components are essentially "unknowns". With upgrades, you've at least got a handle on the performance of the rest of the system.
- ASUS updating utilities are much less useful and "idiot proof" than those of MSI.
- SLI hasn't been completely sorted out yet, and problems can be tough to solve. The problem can lie in the game code, drivers, graphics card(s), mobo, PSU or some combination of these.
For the moment, if I had to recommend one of the two, it would be the MSI K8N Neo4 Platinum SLI. I don't overclock, and prefer the update utility of the MSI board to that of ASUS. I'm comfortable cleaning and updating graphics drivers manually, but not comfortable doing the same for the motherboard drivers or BIOS. Quite frankly, I hate computers, but I love flight sims. My goal is to have a stable, fast, low maintenance system which will run flight sims. The MSI may not be the fastest performer, but in my experience it is stable and easy to maintain. Once I get the PSU back, and can have the techs dive into the system, I may change my opinion.
Sorry for the long first post, but I hope this info will prove useful to some of you. Thanks again for all the work you've put into this thread Pentium Guy.
