Overclocking E6850 and RAM
So I want to overclock my E6850, but I dont know what speed my ram runs at.
I say a video on youtube showing a kid overclocking the e6850 using an intel program? Would that be a good way or just use bios?

Here's Graysky's Core 2 Duo OC guide.

You want to overclock in BIOS because you can't change a CPU:RAM divider with software. CPUZ can tell you the DRAM Frequency.

BTW, what models of motherboard, RAM, and power supply are you running?What computer do you have? And please don't say a white one. - Sheldon Cooper

Motherboard is a MSI P6N SLI
Ram is 2gigs, 800mhz
Powersupply is 500 watt

Since you have an nForce chipset you should be able to disconnect the RAM from the FSB in BIOS. That will keep the RAM at 400MHz (DDR800) when you increase the CPU Frequency from 1333MHz. If you keep the memory linked, lower it to 333MHz (DDR667).What computer do you have? And please don't say a white one. - Sheldon Cooper

How much should I raise the CPU Freq each test? Should I test for stability everytime I increase? Whats a good program for that

Blue screen system crash when torture testing
Im trying to overclock my E6850 3ghz to 3.6ghz.
I can achieve 3.6ghz but when I test it using Prime 95 small testing, it crashes to the blue screen. When its testing, it gets to about 63 (around there) and crashes.
Im doing the 400 mhz x 9.
CPU volt is at 1.38 (default is 1.33)
Northbridge volt is at .30( defulat is .25)
Is there something I'm missing?
I see people get their E6850 stable at 3.6 and higher speeds..

merged this all together since its all related!
First let me say just because someone else's system can do it doesn't means yours will. OC'ing is art not science and even two identical systems can and sometimes will OC differently.
Second you should be jumping it up slowly, testing then bumping it again. You really shouldn't need to change your voltages until you get a steady baseline test. Then if you hit the wall you bump the voltage a tad. Just make sure you watch those temps
edit: I should add, you mention 2gbs of RAM but not a make/model? What are the exact settings you are using (what have you turned off changed ect, including the RAM settings?)

Thats understandable ..
What exactly is a steady baseline test in prime95? All the tests I'm doing never go on for more than 20 mins'. All crashes.. So you think I should start from scratch and increase FBS until it's not stable then increase volt?
And I'm using two A-Data DDR2 PC2-6400 (400 MHZ) 1g a piece.
And I'm going to go in to bios and write what I changed so I can come back and post. BRB.
D.O.T. control: disabled
Intel EIST: ENabled
System CLock Mode: Manual
FSB Clock: 1600Mhz (1333 defualt)
Memory CLock: 800 Mhz (defualt)
Adjust PCI-E Freq.: 100(defualt)
CPU Voltage: +.0375v (So its at 1.368 v )
Memory Voltage: Auto (defualt)
NB Voltage: 1.3v (1.25 defualt)
SB Voltage: 1.50v (defualt)
FSB VTT Voltage: 2% (0% defualt)
Memory timings: auto (defualt)
Got all the sprectrem stuff disabled
So now my current CPU Freq is 3.6GHZ (400x9)
My current FSB Freq is 1600 MHZ
Current DRAM Frq. is 800 Mhz
I had to type this out 4 times because IE 9 beta sucks and wouldnt post it for some reason. Now im on chrome.
