Ram failing ?

Well lately i have been getting some game crash relating to memory and i have been watching it closely and it sits at 3gb used and about 1 gig free at desktop after i ran a game and let it sit for a while.

i am using a 4gb 2x2gb 800mhz g skill ram and was curious if changing out to 4gb 1200mhz ram would improve my situation ?


Motherboard: XFX 780i
Processor: E8400
Ram: G skill 4gb 800mhz
Video cards: 2X 8800gt in sli

was looking at getting this

Here's a small check list you can do:
-Flash to latest BIOS for your particular motherboard
-Go into BIOS and change speed + timing to 400Mhz (800DDR) 4-5-4-12 2T
-Increase RAM voltage (vDIMM) to 2.1V
-Update nForce and Forceware (185.56 is the latest) driver

Incorrect RAM setting or driver issue is the most likely cause I can see when crashing back to desktop.
Also have a household fan directly blasting into the case to eliminate cooling as potential cause when carrying out the list above.

well it is already running latest nforces drivers. and its also running latest bios. i also just changed my timings from 4-4-4-12 2T to your 4-5-4 2T and up the voltage from 2.0V to 2.1V. seems to be taking a lil longer to boot up now oddly. i will be posting a update in a lil bit after i see if it fixes my problem though.

the game was world in conflict


as for cooling i have a 120mm in at the bottom of the case one 120mm out the back of the case then a 160mm in on the side of the case then a high output 80mm out the side of the case and another 92mm out the back of the case between the video cards in a air conditioned room at 70 F


also will there be much of a performance increase if i got that faster ram ?

Check your memory for errors with memtest86+.

guys, if it looks like a mem problem, before doing anything else:

MEMTEST86+!!!

Seriously, never flash the BIOS until every other option has been attempted. Same with timings, etc. Test the easy things first, then go from there.

To repeat, run memtest86+ to check out the ram.
There should be NO errors for a full pass.
If you get an error, run it for each stick individually to identify the bad stick.
You may have to run a good stick in different slots to check the possibility of a bad mobo ram slot.

As to better performance withfaster ram, no you will not be able to notice any difference in fps or application speed with faster ram or better timings.

yes i am running vista 64 bit and no it not at stock voltage at stock voltage my system becomes very unstable but kinda works. and will memtest86+ still work with 64bit os ?
