Right i built my new pc at the start of Dec 07 with the following spec


Antec Sonata III Piano Black Quiet Mid Tower Case - With 500W EarthWatts PSU
Asus P5N-E SLI 650i Socket 775 PCI-E Onboard Audio ATX Motherboard
Intel Core 2 Quad Q6600 Energy Efficient 95W edition Socket 775 (2.40GHz)
Arctic Cooling AC-FRZ-7P Freezer 7 Pro Socket 775 Processor Cooler
OCZ (OCZ2P800LP2GK) 2Gb PC2-6400 DDR2-800 4-4-4-15 DFI (2 * 1GB)
1 * 8800GTS 512mb PCI-E Graphics Card
1 * 160GB SATA HDD
1 * 250GB SATA HDD
2 * NEC Optiarc AD-7170S-0B 18x DVD±RW/DL/RAM Serial ATA Black

Running Windows Vista Business 32bit



Its been spot on since December, but i thought i would add another 2GB memory just to see if it would speed it up a bit,

I put another 2GB in on Friday (2 * 1GB EXACTLY the same OCZ memory as before, the same part number, ordered from the same place), and instantly it started playing up, it would run for a while, and then crash when in game, bluescreening sometimes, other times just becoming so slow i would have to do a re start, then earlier this evening it bluescreened, and refused to boot again,

I played arround with the memory, and it will work with ANY 2 dimms in ANY 2 slots, any combo works, however when you have 4 dimms in it will either refuse to boot or will bluescreen within a few mins.


Any body got any suggestions as to what it could be ?

Its pissing me off now :@ :@ :@

 

have u ajusted the voltages as they can cause that problem i think have a look on the manufactuers website to see what their recomended setting are.

 

OCZ state to run the memory at 2.2v.

The memory in the bios was already set to run at 2.2v before i put the extra 2GB in.

To cure the problem I tried setting the voltage to auto, and it made no difference.


I don't "think" its voltage related,

 

Is it a 64bit machine? I'm not certain but I dont think it is, and you can get problems with 32bit machines over 3.5gb of RAM

Edit: just re-read that your running Vista 32bit. Good chance thats your problem.

 

very common issue with Asus boards, they dont like OCZ RAM i think they said its a voltage issue, u have to run a highier voltage then normal for it to worked properly (as well as a bio flash) as Asus have addressed the issue, do a search on google you'll find 100's of threads on it.

If you've got some different brand ram throw, that in and it should work fine, just to see it really is the issue.
