I'm just curious...which OS are you using 32-bit or 64-bit. Windows 32-bit won't see all 4GB...if you want to use and see all 4GB you'll need to upgrade to 64-bit.

2.84V seems very high for dram ...

What does the bios tell you on the post screen ?

Try testing the ram by installing it individually.

It might be hardware related issue with the motherboard...have you installed the latest BIOS...you might want to test with another brand of memory...if the results come back with the same issue with another brand of memory...it's possible that the motherboard is faulity.

Did you have the DFI LANPARTY SLI DR EXPERT motherboard for a long time with other memory and it worked fine? Or did you have a different motherboard with this memory?

Do you have other memory you can try that you know that works?

jamietonerCommented:
Sounds like both sets are good just not compatible with each other possible due to voltage issues one is 2.8 the other is 2.6. One more thing to try is with all 4 stick installed try reseting the bios defaults with the jumper on the motherboard and see if that helps, if not then you'll need new ram if you want 4gb.

Plain and simple, that board is picky about RAM.

Many DDR boards, despite the fact they are supposed to, simply don't work well with 4 modules installed.
The original specifications [from Intel] for the memory Voltage Regulators resulted in under powered RAM slots.
- That's 4 MODULES. It doesn't matter what size they are.

Your best bet may be 2x2GB modules if the board supports it.
