4 gig seems unstable

Banny · 16 Dec 2007 at 15:10

Have a DS4 rev 2 I think, my first 2 gig is special ops (OCZ) and all was fine running it at 900mhz using +.300v added 2 more gig 2*1024mb sticks and now games are crashing with the .exe having a problem.
Have increased the voltage to .350 games last a little longer.
Do I drop my FSB down or can I keep increasing the voltage, what is the max I can go to.
my new ram is OCZ pc6400 gold stuff.
This was the closest I could get, I am pretty sure this can get to 900mhz easy if my old Special Ops stuff does it no problem.
Any help would be most welcome.
I must add no problems using Vista and explorer its just gaming have only tried COD4 and Crysis and crash out on both after a few minutes.

Well it seems it is not stable in windows, so have increased volts to +.400 and chipset volts to 15% will try this see if it is any better what is the max chipset volts I can.

More ram usually means more stress/heat on the memory controller (in the Northbridge which also has the FSB going through it), so if you have already overclocked your PC on 2Gb, you may have made it a little unstable by uping it to 4Gb. Try winding back the FSB or putting a little more voltage through the Northbridge.

Try adjusting the "high speed DLL" settings and the performance setting, just a thought.

Can it get through memtest without any crashes or errors? If not, then something's definitely up with the ram.

This computer has a P35-DS4 and originally had OCZ RAM in it, but it was unstable and crashed memtest. It's now got the Corsair that's on "this week only" and it's all fine and dandy

We sent the OCZ back for a refund, as it's either faulty or incompatible (if faulty a refund will be sorted, if not faulty and just incompatible I've asked to return it under distance selling regs).
