Okay, Crashman was helping earlier on the PSU section of the community. I decided to bring it here to the motherboards and chipset section.
quick reference: a8n-sli, amd athlon 3200+ 90nm, 2xsamsung 160 satas going for raid 0, 2x512 kingmax 2.5 pc3200, NX6800 [pcie] by MSI -- motherboard is in the air, not accidentally grounded by anything -- motherboard has not been shorted out by my knowledge -- i have gotten displays a few times, even into the windows setup a couple times -- sometimes it works, sometimes not. here is the long conversation

IS ATX12V ATX 2.0? IT SEEMS LIKE IT!

I can't hardly figure this out! Is ATX12V another way of naming ATX 2.0? Does this mean every case I look at with an ATX12V PS actually has a 24-Pin ATX 2.0 Power Supply?

RAAAR!!!

thanks,

doug

Re: IS ATX12V ATX 2.0? IT SEEMS LIKE IT! [re: dougyfresh]

bleh....I'm pretty sure I found that ATX12V is not necessarily ATX 2.0, just that it has the extra 2x2 12v connector. I know ATX 2.0 is new...but my Asus A8N-SLI has to have a 24 pin connector in it. Where can I find a bunch of ATX 2.0 cases or power supplies? I've been looking for about a couple hours all over the internet and local businesses.

crap.

Take a look at The Picture. See that 4-pin power header next to the AGP slot? See the 4-pin square header next to the keyboard/mouse ports?

These types of boards DO NOT NORMALLY "REQUIRE" A 24-PIN CONNECTOR. You can use a 20-pin connector and the extra 4-pin connector instead. The 20-pin connector DOES FIT the 24-pin socket, it's offset to one side, and DOES WORK with boards that are made to accept either type of power.

Re: IS ATX12V ATX 2.0? IT SEEMS LIKE IT! [re: Crashman]

yeah, it does fit. I've been trying to work with this new system lying by my feet for a while. Maybe you could help me out....right now, ive got my 400w PS. It has a 20 pin male regular ATX connector out of it plugged into the motherboard, with 4 of those pins left open. Ive got the molex plugged in (by the pci-e slots), and ive got the 2x2 12V thing plugged in as well. Ive gotten this system to start up about 5 times now, but its very inconsistant. I cant seem to get it to start up now. I was having a little luck by clearing the CMOS and trying to restart...but now that is not working :(  . ***I HAVE HAD THIS MACHINE UP AND RUNNING FOR A TIME******* , the problem is, it seems when I shut it down, it has a real hard time getting back up. Sometimes it sends out a second long beep every few seconds, sometimes it doesn't. this is the weird part...why is it so random? --I HAVE NOT SHORTED OUT THE BOARD.

keep up with the help crashman...i love it

Re: IS ATX12V ATX 2.0? IT SEEMS LIKE IT! [re: dougyfresh]

A little digging around says the second molex is for adding power to the PCIe bus for dual video cards, so the one next to the PCIe x16 slot doesn't need to be used for a single card. Also, my appologies for saying it was next to "the AGP" slot previously, force of habbit, it's a PCIe slot, AGP cards won't work.

bleh, i unplugged that molex next to the pci-e ....but my monitor still isn't getting a display (yellow)

darnit!!

it seriously should be working correctly.

What power supply are you using? Most cheap supplies are not providing stable voltage under that much load on the 12v line.

I tried seeing if I would get a display this time by unplugging both my optical drives, fans, and both my SATA drives....no result, I'm still not getting a display. This sure is pissing me off :(

Hey, that DOES look like a good power supply! So, now you still have a problem!

What video card are you using?
Are you certain the back of the board isn't grounded to a spare standoff?
What RAM are you using?

Re: IS ATX12V ATX 2.0? IT SEEMS LIKE IT! [re: Crashman]

I am using 2 512's of Kingmax pc3200 that were in my old system, never had a problem with em. I am also using this new MSI NX6800 , pci express of course. I don't have enough money for my other 6800 yet, tee-hee. I've gotten it to display several times.

--
ok, i just took the mobo out and found a screw that was pinned under it, but once I placed the motherboard back in and set it up again, still the same result --> no display.

Re: IS ATX12V ATX 2.0? IT SEEMS LIKE IT! [re: dougyfresh]

I plugged that molex in next to the pci-e just to make sure, thats what was causing the beeping. You said that you thought you only needed to have that plugged in when running dual video cards, I think you are right.

Re: IS ATX12V ATX 2.0? IT SEEMS LIKE IT! [re: dougyfresh]

WOW WTF?

I'm just a foolin with this machine some more, and it just started beeping again (same beep, about a half second-whole second beep repeating each 2.5-3 seconds). The problem is, I DO NOT HAVE THE MOLEX PLUGGED IN BY THE PCI-E SLOTS THIS TIME. This means that this beeping is something totally random, because it has happened with and without that molex in, and sometimes beeps and sometimes doesn't.

WHAT
THE
HELL

I even checked back, and yes, it is in the faq:

Q. Upon starting system, I get continuous long beeps, with no video?

A. Probably a memory problem, the first thing to check is that you inserted it all the way until it clicked

Different hardware reserves different parts of the memory. Especially when moving to a s939 A64 system (with on-cpu memory controller), it is very well possible that (faulty?) memory ranges that were never used are now adressed.

Let me dig up my "DIY - hardware forum - 1st aid"

Generally, it is wise to assemble a new system out of it's case before first use. This to eliminate the possibility of the case shorting the mainboard.

If it somehow locks up during first boots, then best strip systems to it's bare essentials:

- Mainboard
- CPU
- Video (onboard, / pci(-e) / AGP)
- PSU (power supply)
- ONE block of Memory (RAM)

This setup should let you go into BIOS, or at least show an error (no boot device...).

-> If this doesn't work, try swapping one part after the other, to determine which part is wrong. Lend something from a friend, if you need, try 1 block of RAM in stead of the 2 (and don't forget to test the other block alone too). Also try swapping mouse & keyboard! Don't make crazy expenses until you're sure what part is broken. If swapping ram, cpu, video and PSU didn't work, then you may have a broken mainboard.

-> If the above did work, your problem lies in another component (harddisk, PCI card, ...). Add them one by one until you find the part that locks up the system.

If you still have problems with this part, please post back with more details!

Hope this helps ;)

Well, I took out both dimms, tried each one on the B1 slot, thats where it says to put it if you have one module and started the machine with the motherboard in the air to make sure it was not being grounded (I still believe I never shorted it out). The same result still happened, that stupid beeping. Notice its not a fast beeping sound, it is a beep, then a decent delay, then another. I had this memory in my old system and never had a problem with it, it worked great. Also, I had this system started up a few times, memory usually won't just go bad. That means my memory is good and my PSU is good. Is my motherboard broken? That is all I can think of.

***EDIT***
I tried starting up with all the memory out, and the same beeping happens. This could be a bad thing...either something on the motherboard that controls the dimm slots isn't working right or both my sticks of memory somehow are broken....okay....

sadface :( 

**EDITED AGAIN**
i just tried my memory in my old system, boots up fine. It said both 512's were working correctly.

I just reconnected everything and then it booted up...this is what is annoying me-- I havn't changed anything!! It was doing this last night too.. I had everything fitted correctly, memory in the same dimms, both ATX powers are in the same slots, the graphics card...can't really be in wrong. Bleh, I just don't know what is going on.


welp... seems to be working every time now. It looks like I made some dumb mistake somewhere, but dudes...seriously thank you for your time you put in to help me. I really enjoy having people help others like this. I really like Tom's Community, and will continue to post here.
