Ok i recently got this and these system specs

E6300
Biostar TForce 965PT mobo
G.Skill DDR2-800 5-5-5-15
Rosewill 450w PSU
7900GS (no OC)

Also i have an Arctic Freezer 7 Pro

Ok now i cant seem to get past 350x7 stable. My CPU is very cool and even when i up the voltage it doesnt help. Im running the ram at 2.0v as well.

Now what I think it is is my RAM is being pushed like a mother. I cannot seem to find my FSB : DRAM ratio in my phoenix award bios at all. I have checked and checked only to find how to change the mhz speed and the timings. Im starting to think my Mobo doesnt offer a ratio change but that can't be. The OC options of this board are awesome so dunno.

At a 2:3 ratio CPU-Z says my DDR2-800 RAM is running at freakin 525mhz!

First off thats ****ing awesome for DDR2 800 ram. Also when i made it 360 it was like almost 540mhz. I doubt the ram can take anymore mhz since its at this 2:3 ratio.

This does sound plausible right? Im only 16 and my first time ever OC so I cant say for sure. But i know enough to think that is the reason. Now, if it is the reason is it does anyone know where I might find this FSB : DRAM ratio? I've looked and looked in my BIOS and cant find it. But i also know that this board was said to reach very high OC, which makes me think unless they had INSANE RAM they were able to change the ratio. Any help would be appreciated.

lol, welcome to OC.net

First off, you need to look at your "system memory frequency" right under your memory voltage selection. Change that to 533 (which is 1:1), or the OCed value of your processor. Next boot up, it should read as 1:1. If not, keep playing with that setting until you find what you like.

thing is my bios I read dont have a system ratio that I can set to 1:1 or so. Even when i set my mhz to 677 then my FSB to 333x7 my ram was running at around 500 mhz to make a 2:3 ratio. I mean if it could run like that at a 1:1 ratio I could get some serious OC's. But untill then I have no idea how to change it to 1:1 ratio while the ram is at 800.

Do you have a Screenshot/picture of your system BIOS?

Biostar motherboards are not well known for a huge array of BIOS options. However, as a 2:3 ratio has been set, there will be the option to change the system divider ratio.

The system ratio should be contained within the same page as the CPU overclocking options.

It will give you either:
Integer clock speeds for Memory (667MHz, 800MHz, 1066MHz)
Integer Ratio's for System Dividers (2:3, 1:1, 4:5).

You said you could find how to change the Memory speed? If so that is the option you will need to use to change the divider of the system.
The Integer Clock Speeds for Memory will change depending on the system overclock. These values will not be Integers in reality however, but you do not need to worry about that

my BIOS give me the option to set them at a certain mhz. 533, 677,800.
When I booted it up with it manualy set to 266 and then 533 ram it booted up and CPU-Z said it was a 1:1 ratio. Yet it wont even post with my CPU set at 333 and ram at 677. Although it's not the ram. I have this ram running stable at 531mhz in a 2:3 ratio. So what Can i possibly do? Why wont it boot at it manualy set at 677mhz

sounds like the only thing left to do is flash the bios(if u think ur version is lacking the option u want) or swap out the ram and try it, even though u clearly said the ram is good.

well i need to figure out why it wont boot with ram manually set to 667mhz and my fsb set to 333
