Please Help! No POST on P5N32-E MB w/ 4x1gb TWIN2X2048-6400C4


Recommended Posts



i am getting pretty desperate here, as i need to know if this is a possible problem with my mobo, or if i need to actively do something to get this system to work properly...


i purchased my PC from an individual who builds and sells, and he says that my problem has to do with the mobo's bios...i have 4 x 1gb of these RAM sticks, and up to 3 will run smoothly and problem free. however, when you plug the 4th DIMM in, you will get absolutely no POST. lights, fans, everything goes on, but absolutely no action up-stairs, if you catch my drift. all of the modules seem to be working just fine...no bios settings have yet been altered...


i'm starting to suspect it's a faulty mobo, but i wanted to ask the forum before i made any rash confrontations. i am also waiting on a new cooling unit, as mine fried (coolit eliminator, faulty revision) so as it can be noted, im having a hell of a time with this expensive investment, and i also cant run my system until i get the part back...please, please someone offer me advice to pull me out of this annoying financial quagmire.

This is not uncommon with the 680i based motherboards so it leads me to think that this is an issue of the 680i chipset. The only methods that I have seen achieve results with this issue is an RMA and a new board or a move to a 2 X 2048 DRAM Kit. The second method does mean you retain a motherboard that will not accept 4 DRAM banks populated though.
