a7n8x not posting.
Hi,
I just got an Asus a7n8x motherboard, amd 2800 xp processor and a set of corsair pc3700 twinx ram (512).. i set 'er all up but it won't post! I've read about other people having problems with that motherboard and have tried every recommended remedy - I've reset the cmos numerous times, hit reset button countless times, tried every memory config.. unplugged everything.. checked all the jumpers but it keeps telling me there's a memory error which i think is a bs message because it only says it half the time. - every once in a while, after resetting it a while, it looks like it's booting, but it hangs again. Should i look into buying new ram? Anyone seen this configuration working? Is my mobo f'd? thanks |

First, use only one of the memory modules till you get it working
100%. What video card? Is the power supply adequate? A7N8X uses 5V for CPU power, and combined with a high-performance video card it would be prudent to use a name-brand power supply with =200W combined 3V+5V rating. Is the system bare still, nothing but one memory module, CPU/fan, video card, power switch connected? Is the board inside or outside the case? If inside, is it possible you have something shorting against case or other wires, or ... ? With a new system build there's a lot of little things that could go wrong, it could be a bad board or something not obvious without more detail or perhaps if looking at the system. IIRC, that board is "supposed" to revert to 100MHz FSB if it fails to POST, so the memory should be OK to get it POSTing, would only err if it's unsuitable at higher memory bus speeds. How many of these parts are tested working in another system/environment? I have a 480W power supply so that shouldn't be an issue. It's strange because it only gives a vocal warning about the memory 3/4 of the time and it whines with one stick of mem too. I unplugged the cpu fan from the board (but leave it running of course) and if it doesn't give a warning about the memory, it will say that the cpu fan isn't running - but only one warning at a time. Should I be getting beep warnings? I'll have to find another system to test the parts.. this is getting very frustrating. thanks for the help though. |

If so go to the "Main Menu" and select "Halt On" and change the value to "No Errors." Save and reboot. Does the board complete POST now? If not try just one DIMM or look hard at your power supply. All 480 watt power supplies are not created or rated equally. -- callsignviper The truth is out there. You just have to look in the right places and ask the right questions. |

I have absolutely no idea what happened, but i installed one DIMM before and it didn't work... came home from work and tried it again a few times and now it works and I was able to get into the BIOS setup! ...... afraid to reset it though to connect my SATA drive. The powersupply is a thermaltake 480W silent purepower, it's defenitely not the problem unless there's a short somewhere which is what i'm thinking is the problem now. anyways, thanks for all the help guys.. greatly appreciated -Steve |
