Just bought a 2gb set of OCZ Dual Channel Ram for my computer
Exact specifications-

OCZ Performance Dual Channel Kit - memory - 2 GB ( 2 x 1 GB ) - DIMM 184-PIN - DDR

Storage Capacity 2 GB ( 2 x 1 GB )
Upgrade Type Industry standard
Technology DDR SDRAM
Form Factor DIMM 184-PIN
Memory Speed 400 MHz ( PC3200 )
CAS Latency CL3
Features Copper heatsink , unbuffered
Supply Voltage 2.6 V

To add onto my original ram-

OCZ (OCZ4001024PDC-K) 2x512MB DDR400 PC3200 CL 2.5-3-3-7 Premier Dual Channel Kit

ULN Technology: (U)ltra (L)ow (N)oise shielded PCB
Lifetime Warranty from OCZ
1GB (2x512MB) kits
Copper Heatspreader
400 MHz CL 2.5-3-3-7
2.6 volts
184 Pin Dimm
Unbuffered

For my Motherboard-

MSI K8N Neo4-F SKT939 nForce4 chipset Dual DDR400 PCI-E ATX

Main Memory

Supports dual channel DDR 266/333/400, using four 184-pin DDR DIMMs.
Supports a maximum memory size up to 4GB without ECC.
Supports 2.5v DDR SDRAM DIMM.


I put the 2 sticks in the 2 free slots. I started up the computer, powered up but nothing happened on screen (black) so I removed the original ram and put the new stuff in the slots where the original ram was. Tried to start again but the same thing happened. Took the new stuff out and put the old stuf back in and started the computer without any problems.

So... Is the ram faulty
Or... Does the motherboard support that ram. All the specs of the new pair are the same. The only thing I was wondering is because it's a larger size (2gb instead of 1gb) the 2.5v limit on the motherboard cuts it off or can't power it (the memory is 2.6v same as the original).
 
Are you running a vDimm of 2.5V? Set it to 2.6V in the BIOS then add your new RAM back in and see if it works then. 1GB PC3200 modules are supposed to require 2.6V (some may be able to run at 2.5v)
 
It have tried what you suggested- it set it to 2.60v and 2.70v on to two atempts I made but still the computer fails to display anything on the screen. Still works fine with the original. Another thing i read was that ECC memory might cause the system to do exactally what i described (black screen), but i cant find any evidence that the memory I bought is ECC
 
Since both have heatspreaders the only thing you can do is look at the sticker on them. If it says ECC then it is, otherwise it isn't.
If there are no heatspreaders on them count the chips, if its divisible by 3 it's got a parity chip on it and is ECC..I suppose you could look at the bottom and count the chips that way if theres a heatspreader on them, but they should be stickered correctly, I don't think I've ever seen a mislabeled stick of RAM.
 
So it should all be compatible? Ill have to get in touch with OCZ or Komplett, see if I can get it replaced.

Is there any chance that it could be the Motherboard? It says it supports up to 4Gb.
