My mobo wont work w/ new ram

[MrPanther0]

My question/dilema is this. I recently bought an Asus a7n8x-x Nforce2 ultra 400 mobo w/o IGP.
At the time I was running 256 MB PC2100 RAM because I was in the process of upgrading. I now have 3 seperate DIMMS of PC 2700 CL 2.5 with 1 GB each. I recieved these as a gift and all i know about them is what i just stated and it says "g-tek" on all the modules on each side. It has 8 banks on each side and is 184 PIN memory. It runs fine with my old memory and even with just one stick of the 1GB PC 2700 memory I see no display and startup never commences. I don't hear a beep at startup. It seems to me that the mobi doesnt reconize the memory. Do I have to flash the BIOS or change the CMOS jumpers? Or maybe I have to just change the BIOS settings. Thank you very much for your help in advance.

Registered and/or ECC RAM is not supported by this chipset. If the said memory modules are Registered and/or ECC then they're not compatible.

I don't know if they are ECC or registered is there any way possible i can find that out? All it says on the sticks is "g-tek" and Pc2700 DDR33 "warranty void if removed". I recieved these DIMMS as a gift. If I sell them does anyone have any recomendations on where to sell , how much to sell for.. etc..

<i>The general rule of thumb in deciding what type of memory you need is to look at what's already installed in your system. To find out if you have ECC, parity, or non-parity memory, count the number of chips on the module. If you can evenly divide the number of chips by three or five, the module is ECC or parity, if not, then it is a non-parity module.

So what if your system does have ECC or parity memory (the chips are evenly divisible by three), how do you know which one you have? One way is to look at the part numbers on the chips of your module. If each chip has the same part number, you have ECC.</i>

<i>You can tell if you are using registered memory by looking at one of the modules currently installed in your system. If it has one or more small black chips mounted horizontally on the module, you have registered memory. If not, you have unbuffered memory.</i>
