I have increased my Memory Voltage from 1.95v to 2.05v and found a huge improvement in stability while playing PC games but its not 100% stable.
I still get freezes and crashes while playing for maybe 4-5 hours. Ok, ya, I game a lot 
and built a rig for it.
What is the max voltage I could go up too?? I am a bit afraid to go higher as this was expensive RAM
Here r my specs..
nVidia 7950 GT OC'ed from 550/700 to 650/800 stable
AMD 64 AthlonX2 4000+ AM2 2.1 ghz OC'ed to 2.85 ghz stable
CoolerMaster 500w PSU
BioStar TA760G M2+ motherboard
WD Cariar Blue 320 GB WD3200KSRTL SATA
RAM
Brand CORSAIR
Series DOMINATOR
Model TWIN2X4096-8500C5DF
Type 240-Pin DDR2 SDRAM
Tech Spec
Capacity 4GB (2 x 2GB)
Speed DDR2 1066 (PC2 8500)
Cas Latency 5
Timing 5-5-5-15
Voltage 2.1V
Multi-channel Kit Dual Channel Kit
Heat Spreader Yes
Features DOMINATOR with DHX Technology and Airflow Fan
Is Cas Latency and Timing adjustable stuff?
Should my voltage be at 2.1V for stability?
What is 5-5-5-15??
From BIOS I got this info..
Memory Over Voltage choose from 1.95V, 2.05V, 2.15V, 2.25V.......2.65V
CAS Latency 5.0
RAS/CAS Delay 5CLK
Row Precharge Time 5CLK
Min Active RAS 18CLK
RAS/RAS Delay 3CLK
Row Cycle 23 CLK
All of this stuff is adjustable in my BIOS
I'm a dangerous noob and to prevent a fire in my house or unnecessary abuse of expensive RAM any feedback is helpful.
Thanks, Matt (goel0012)

If you system is crashing after 3 or 4 hours of gaming, it is not stable.
You do not know whether you are crashing because of bad CPU settings, bad memory settings, or bad GPU settings.
Or bad thermal problems.
Suggestion:
Write down all of your settings. Put everything to stock settings and start over.
Start your RAM voltage to 2.05 volts. Set the timings to 7-7-7-20.
Start overclocking the CPU. Once you get up to around 2.5 GHz., start running Prime95 small fft's for 8 - 10 hours. Need to watch your temperatures. Work up to 2.8 GHz if you can.
Now try to work your memory timings down to 5-5-5-15 if you can. Use the Prime95 blend setting for this.
When all this is stable (I test for 24 hours), work on overclocking your video card.
Yes, it's tedious and time consuming, but it is what you should have done in the beginning.
Or you can just learn to tolerate the occasional crash.

jsc is 100% right. I assumed I had a stable rig but it is obvious to me now that I don't. It's funny to read what I wrote in my initial thread, I actually say that my rig is not stable 
Be gentle, I'm new 
I'll DL Prime95 and roll up my sleeves...or take a nap 
I'll update as I go to tell ya how its goin.
