Default Paired RAM Issue and Question

Hi everyone!
I was recently in the process of upgrading my computer when it occurred to me that I don't know much about the techicalities of DDR Ram.

During my last upgrade my Dual CMX512-3200C2PRO sticks decided to crash my computer in games like FEAR and Oblivion and Call of Duty 2. It seemed to only happen after i put a new GeIL PC3200 400MHz DDR SDRAM in. Now even when i run the old memory by themselves, its still crashes, I feel as though i've done something wrong to cause this.

note: I didn't change any settings when i put the new RAM in. Actually, i dont know what settings to change... I didnt change any settings when i put the original 2X512Mb in, but its been working fine up until now.

note: It works when the new RAM is run by itself.

I dont know what it means when ram is Un-buffered, or non-ECC, or Un-registered or anything like that. How do Dual channel optimized modules work? does my Gigabyte GA-K8U Motherboard (el cheapo) have anything to do with it? And i dont know if having them with another module that doesnt have the negative prefixes will damage anything.

So basically i would like to know,
a) Whether i broke my computer by putting in incompatible memory.
b) What the terminology means so i dont do it again.

These are the specs on the new RAM i put in that seemed to screw things up.


- 184pin, Non-ECC, Un-buffered, Industry Standard DDR memory modules.
- GeIL 5ns 32x8 Density DDR Chip.
- 6 Layers Low Noises Shielded PCB.
- Aluminum Heat Spreader.
- Lifetime Warranty .
- CAS 2.5- 6 - 3 - 3 in 256MB and 512MB
- CAS 2.5- 8 - 4 - 4 in 256MB and 512MB
- CAS 3 - 8 - 4 - 4 in 1GB
- 2.55 - 2.65V

And these are the specs for my Old Corsair RAM.


2x184 DIMM
Black XMS ProSeries

And these are the basic Specs for my computer.

AMD Althon XP 64bit 3000+ (TT Golden Orb Fan)
2 Gb Ram (currently running 1 gb.)
Gigabyte GA-K8U Motherboard
Windows XP corp ed. SP2 (windows updates enabled)

I'd like to be able to run both sets of RAM.
Thank you for your time.
