First boot. Asus P5n32e-sli doesn't POST. - Page 4

post #31 of 55
I have this board (actually on the second one) and some high voltage RAM. I had all the symptoms that you had because the board undervolts so much. By default it's at 1.8v. My RAM defaults at 2.1. I did a lot of head scratching trying to figure it out. Solution was to buy some cheap 240 pin Corsair stuff and boom I was able to post long enough to set the voltages and I was fine.

I won't get into all the other trouble I had with this board.

Good luck.

I am now on my third P5N32-E SLi as both of my previous board's had faulty lower PCI-Express 16x slots. I would get the exact same symptoms as you're getting, no post nor beeps. But this was only when a second card was installed in the bottom slot and it would boot as normal with a single card in the system. I know that you're only useing a single graphics card but its possible that both of the PCI-Express 16x slots on your board are faulty, especially as this is a new build.

When I first got my P5N32-E SLi it wouldn't even power up at all and none of the fans would move as I originally tried useing a 4-pin power cable for the CPU 5v+ that connects onto the motherboard. Replaceing this cable with an 8-pin fixed that problem. You could give that a try but given the information provided in this thread I think that both of your PCI-Express slots are faulty. Your only option after trying an 8-pin cable is to RMA the motherboard at this point as there really is nothing more you can try. Usually I would suggest updateing to the latest BIOS but this is impossible to do if you can't even POST.

note...........leave it on for around 10 seconds just to be sure ..

Make sure your system speaker is connect and that no USB connectors are reversed.

I'm beginning to think this is the problem because I don't think the board will even POST if the memory isn't right. It isn't possible to put DDR memory in DDR2 slots is it? Because that's all I have at the moment. The other possibility I hope it isn't is there's something wrong with the CPU. I can't imagine the motherboard is faulty because of all the lights turning on in the motherboard.

Being that another member of this site was using this board not too long ago with everything working, I doubt there's something wrong with the PCI-express slots. I tried both, and the result was the same. That, and there was a loud squeal that came from the videocard when I didn't plug it into the psu. That makes me think that it was getting some power from the board itself.

I've left it on for probably up to a minute on some tries, still nothing. Nothing smokes up or makes weird noises, it sounds like everything should be working, but nothing really happens.

How does that happen? Every USB device I've used has only fit in one way?

I tried that too, no beeps. The only time I've heard a beeping type sound from this setup is from the videocard when I didn't connect the power. It seems like I've gotten to the point where the only next step is to try to boot with different parts.

Quick question though, the system has to go through it's boot process before I can press delete and get into the bios right? I was thinking that maybe if I hook up my thumb drive and press Alt-F2, I might be able to EZflash the bios. I don't want to try it unless someone lets me know beforehand that it'll work because I don't want to take the chance of just ruining my motherboard. Thanks for the help, hopefully I find the source of the problem by the end of the week.

IDK about the easy flash, sry.
DDR will not fit.

Try one more thing, use the Power adapter that came with the card, the double molex to PCI-E adapter. Make sure you come off seperate rails with the adapter.

Unfortunately no, DDR is 184-pin, DDR2 is 240-pin, it wouldn't physically fit. Because that's all I have at the moment.

My motherboard's green LED would light up as normal. Just because fans spin or power LED's come on doesn't elimiate the possibilty of a component on the motherboard being faulty. Look at it like this, in the same way that a system is made up of multipler components, CPU, RAM, drives, etc, a motherboard is also made up of different devices, NorthBridge, SouthBridge, device controllers, bus's and of course the very tracks that link these devices together.

Unfortunately, with a faulty motherboard component you have to replace the whole motherboard as its not practical to remove something like a faulty slot or chip to solder on your own in the same way that people replace something like a faulty DIMM as RAM is designed to be removed. Anyway, do try useing an 8-pin cable to power the CPU instead of a 4-pin but I'm pretty sure that the PCI-Express 16x slots are dead seeing as you've already confirmed that the graphics card is seated correctly.

If this is a second hand board and you have never seen the board POST yourself then its possible that the member could be telling porkies about its condition.

I'm sure that there is power flowing through the board but just because power is flowing through the board doesn't meant that the compnents that make up the motherboard are operateing correctly, if that makes sense.

Either way, I've just thought of something. Have you tried booting without a graphics card installed? I know that you wont be able to see the POST but it would confirm weather the PCI-Express 16x slots are the problem and not the MCH as you shoud hear the usual POST beeps even though your unable to see anything on your monitor.

Try everything disconnect and connect, even with the CPU. My P5n32-E sli always has the same problem as yours. With green led on, fans spin, video card fans running, but no post.

Last weekend I took the mobo out and lapped my HSF. Before this, I reassemble the rig naked. The same problem happened. What I need to do is to reset CMOS, remove battery, disconnect the mouse & keyboard and power on. and it post. And I reconnect every and no problem at all.

After lapped the HSF and put back on the CPU, the mobo could not post as usual. The above trick could not work. I then took out the CPU and everything, remove power cord, reset CMOS, took out battery. Put back CPU, HSF, battery, VID, RAM and power on, it post. Put it in the case, everything work fine up to now.

Maybe I'm naive, but the guy's got a pretty good reputation on this site, and I haven't seen one post of his that says he accidentally broke the board or anything, just that he got a new one. I just bought a $20 (with shipping) stick of Corsair 1.8v ram. I figure I can test that out, and if it doesn't work I might still find it useful at a later time. That, and it's only $20.

I'll let you guys know what happens good or bad. Thanks for the help.
