[Solved] Overclocking CPU and keeping RAM stable

This is the issue I'm currently having, I want to overclock my CPU I haven't been able to draw a line yet where my RAM becomes unstable.

This is my system:

CPU: i7 860 2.8GHZ @ 2.94GHZ (Thing is 750, 860 and 870 are spos to be stock with 133 Bus speeds, and 860 is spos to have 21x multiplier... even though I never touched it, it has a 22x multiplier on the desktop but a 21x multiplier in the bios.)
MB: Asus Maximus Formula III
RAM: 4x2GB Patriot Sector 5 1333mhz Ram, right now the RAM is at 1333mhz
GPU: XFX 5870 @ Stock ( Having trouble overclocking that right now)
PSU: Corsair HX850W
CPU Heatsink: Coolermaster V8, I was planning on putting a higher end FAN in but after installation into the Coolermaster 932 case which wasn't made for P55 boards I decided to never touch the cooler for awhile again. It overhangs over my RAM so I took the ram cooler and just wrapped it around the intake of the cooler and its fits perfect =)

The computer is safe for overclocking here is the heat info:
@ Stock
______
IDLE: 29C
100%: 49C

@ 3.6GHZ
______
IDLE: 34C
100%: 55C

Perfectly acceptable temperatures but problem is my Computer is crashing after about 5 mins within a game but works fine on desktop so I drew the conclusion that the RAM was at fault, I turned the ram down to 1066MHZ but that was actually 1380mhz at the 3.6GHZ overclock but it didn't work apparently. So my question is how can I made the RAM stay at the stock clocks and get my CPU to about 3.4-4.0GHZ?

EDIT: Under Overclock the computer works fine with Prime 95 other then the fact in random 4 of the workers will cut out right after starting but I managed to heat test through other methods.

I bumped the voltage and it worked but Running a bit too hot, I use more of my GPU power then my CPU power. I had it to 4GHZ at 1.35Vcore and 40C idle and 85C Max which is a tad... well big tad high.
