E8400 oc question

[trance4850]

I oc e8400 to 3.6ghz. I done fsm to 400 and cpu voltage for 2 click. But doesnt touch ram configuration. Do i have to?

Plz help me. Do i have to set dram frequency to 801? Or leave on auto

 

[theAnimal]

What speed is it running at?

 

[richardscott]

auto will set the min value at 800 anyway use cpu-z to see ure mem speed.

 

[trance4850]

Cpu voltage ir 1.1250v

I cant use pc because i havent got hdd now. But i wanna know to future. Is 801 ok? when i push fsb strap to north bridge to 400 than i can set dram to beautiful 800mhz. And how i can do fsb:dram 1:1 ? i cant set dram to 400hgz. 800 is min. So it is 1:2

 

[richardscott]

yea tecnically it is 1:2 because its a fsb of 1600 and mem of 800 but everyone calls it 1:1. 801 is okay for 800rams

 

[trance4850]

Why fsb 1600? Fsb-400mgz dram-801mgz. So i need set fsb strap to 400 or not? And big thx to you because you always help me

 

[trance4850]

And how about seting called dram command rate. Do i need set 2 there or leave auto?

Your RAM is already at 400MHz. Because it's DDR2, you multiply the base frequency by 2, or divide the effective clock by 2.

800MHZ DDR2 RAM is actually running at 400MHz.

The FSB (I believe) is quad-pumped, so it's 400x4 for your total, but it's the base one we're worried about.

400MHz FSB and 800MHz DDR2 RAM is in a 1:1 ratio.

Auto is fine.

 

[trance4850]

It's 400x9. So if i understand corectly i dont need to configure any ram setings and run ram test? But do i need put fsb strap to 400?

 

[trance4850]

Anyone

 

[richardscott]

no if you can run the fsb strap at 333 you will get better performance anyway.

 

[trance4850]

How about 1 part of question?

 

[richardscott]

? well your ram is running stock so just leave it and dont bother checking for stability on it as it is running stock, as for fsb strap to 400 it makes no difference all it means that if you choose the 333 strap then your ram will use a divider to run at 800mhz

 

[trance4850]

Ok than i will set it to 333. Thx for help

 

[trance4850]

Many people on google use strap 400 on ddr-800

 

[richardscott]

Yea because there 333 strap isn't stable enough, all the higher straps allow you to oc more, so mb makers sell the better ones with official support for the higher straps. eg a 1600mhz board costs more than a 1333mhz

 

[trance4850]

Maybe you know this cpu stock voltage?

 

[richardscott]

no thats the vid of the cpu u can find it with cpu-z everest etc.

 

[trance4850]

Do i need to set config like pll voltage dram voltage nb voltage?

 

[trance4850]

Do i need to set config like pll voltage dram voltage nb voltage?

 

[richardscott]

not if ure oc is stable, if you wish you can manually set them low such that they dont get as hot and will loast longer but most of the time they should be fine with such a mild oc

 

[trance4850]

Thx a lot. Youre the best
