Ram expert needed badly

[Onyx Paladin]

I have a very simple question, however, I do not know enough about ram to know the answer. Here is my problem.
What type of difference would there be between the following....
512mb pc3200 cl2.5 64x64 nonECC unbuffered buffalo ddr
512mb pc3200 cl2.5 32x8 nonECC unbuffered buffalo ddr
Here is why I ask.
According to 1stchoicememory.com's compatibility listing, for either the asus a7v8x-x or a7n8x-x, you have to have name brand, high grade, 32x8 or 16x4 cl2.5 ddr ram.
I bought what was listed as a 32x8 stick of ram, but when it got to me, it was 64x64 chips instead.
As you can read in the post asus a7v8x-x problems, I have encountered two of these boards that give the exact same I/O error when using either the 64x64 stick I received, or, pc2100 ram which runs my a7a266 board. Two known good sticks totalling 1Gb of ram.

Could the different chipsets cause the I/O error: Status=000002B9 and cause the bios and motherboard to 'see' the drives connected to the ide ports, and not be able to communicate properly with them? All the ram I have tried, which works fine in all the other systems I have, have failed when trying to communicate with the drives, all of which are known good.

Ram experts out there, I could sure use your input, asus tech support has not addressed this question when asked.

I would move this to the Motherboards forum, but it's a double-post too. You have 2 pages of responses there already. I'll just close this and link back there.
