Hey every one! I'm new to Overclocker.net, here we go!

Okay I want to get the most out of my little monster. When I OC my CPU to 3.2 it changes my ram ratio (Stock ratio is 5:6 - OC is 1:1). The ram is OCZ Vista upgrade DDR2 800 5-5-5--15 @ 1.8v.

I was wondering if changing the timings would give me better performance and how would I do this?
Also make my Ram run faster.

Any other ideas that would help this monster that could, that would be great!

You need to unlink the RAM from the FSB to stop it from changing, but a 1:1 ratio is usually best anyway. I have never used that RAM or mobo, but you may be able to get the RAM over 900MHz with just a slight voltage bump. Be sure to get the maximum stable CPU OC before trying to OC the RAM. It is usually better to up the speed than to tighten the timings with RAM. To raise the speed, you will probably need to unlink the RAM from the FSB but I am not sure how to do this on your mobo. I usually keep mine unlocked and just manually set everything.

Definitely look for your max clocks on the CPU before going after the RAM. When the CPU is stable then you can unlink the RAM and bump it up a little at a time just like you did the CPU.

Okay 3.0ghz is good for me, its good, its fair, it works. How do i unlink the ram. and since its DDR2 800. max is the max speed and volts i want to push?

dont go over like 1.5v id say stay below 1.4v if u can.

OKay stock volts are 1.8v

i think he's talking about vcore. The ram can probably take 2.1v but you'll want to work up to that.

He meant CPU vcore I think.

Either way, that board cannot unlink the memory. There are a few easy solutions though. If you run at 400FSB, and keep the memory linked 1:1 you will run it at 800mhz exactly. 400 x 8 = 3.2Ghz, which should be a piece of cake for an E6750 (give or take around 1.35v).

Really good advice. I have crappy Corsairs that don't overclock so I had to decide between running it at its rated 1066mhz or going with a lower memory multiplier and higher CPU clocks.

Thank you for this advise, I will try this next time I restart. Im running Prim95 right now @ 3.0Ghz and the temp is 46*C (been running for about 2 hours now). and the Vcore is 1.23V

Is that 1.23v in the bios or idle in Windows? If that's your bios setting you might get away with 1.30v at 3.2Ghz.

windows @ full load. i just changed it to 3.2ghz now im prime95 with a 1.25v
