Defective Asus P4S8X (SiS 648 chipset)??
I recently purchased an Asus P4S8X with the SiS 648 chipset and have had nothing but a bad experience.
Allow me to explain... I intalled the motherboard into the case and turned it on for the first time and was excited that it actually worked. Then it shut off by itself. I tried it again, same thing. Then after a few more tries, it shut off almost immediately after I hit the power button. The only things that are attached to the motherboard are the video card, the RAM, and the CPU. The system's POST beep is one short beep and when it actually goes into the BIOS, sometimes with an error message saying the CPU's frequency is wrong and sometimes with it saying the memory frequency is wrong... and sometimes it goes through everything fine and stops at "No floppy drive installed." The second time I try and turn on the system, it generally doesn't make it to POST. If I do manage to get something changed in the BIOS and save and exit, when it restarts, the monitor stays in stand by and there's no POST beep, and then the system shuts off. This morning I had the mobo outside the case and the computer ran for at least 15 minutes. Then I put it back in the case and it started again. But last night it was doing the same thing outside the case as it is now inside the case. I have tried switching power supplies and video cards between my old and new computer with no luck. Both new items work fine with my old system and the old system's components don't fix the situation with the new system. The motherboard is in jumperless mode. I have read over at Asus Boards that DDR333 RAM isn't compatible, even though the box says it is. I've also read lots of other horror stories over there, so I'm just wondering... Do you think the board itself is defective from the situation I've posted here? Here's the specs of the system: Asus P4S8X motherboard Intel P4 2.53ghz processor Abit Siluro GeForce4 Ti4200 (128mb) graphics card Samsung 512mb DDR333 (PC2700) RAM stick Thanks! |

Have you tried using the Default settings in the Bios? It should offer to autodetect your cpu & memory timings. If they've been set too high, that could cause trouble.
The fact that it's shutting down, rather than restarting, though - makes me think you might have a heat or power supply problem. Check your temps in the "PC Health" or "Hardware Monitor" section of the Bios when you can. Is your power supply from a reputable maker, and does it have the special P4 attachment plugged into the motherboard? . . . Gary __________ p.s. ....looks like it's time to put this thread to bed. Saw your other thread's post, where you mention you checked the temps & used thermal grease instead of the pad when reseating your heatsink & all is well now. Congrats.

Yes, the system is working, but if I change anything in the BIOS pertaining to vcore, RAM speed, or the CPU settings in general, the system tells me that the system failed to start due to CPU overclocking.
It does this even when trying out the settings that fixed other people's problems with this particular motherboard (which can be found over at asusboards.com). Even after changing the settings back, it wouldn't start and I had to reset the CMOS. During the time of changing things, the CPU temperature would be around 190 degrees, then gradually heat up to over 200 and the system would shut off (which I now understand as being helpful rather than a pain in the butt like it was a few days ago). When I use the default settings the CPU runs at a normal temperature, usually right around 100 degrees. There are some definite horror stories with this board and I wish I didn't have one to add to the pile. I am returning the board tomorrow and going with something else.

Yes, there seems to be some problems with that Asus board. Someone here put up a link to it over on the Asusboards forum and quite a few members there who were using it were having several issues with it.
Historically, Asus has been a rock solid build - I guess this was their rotten apple. Maybe they may get some fixes out for it though.

If Asus is having issues with their 648 board, I would be leery of ALL other 648 boards right now.........
