I like to hit 4gig on my e6400 p5b with air

[markymoo]

Is it possible to hit 4ghz with 6400 on air with ddr2 800 memory using p5b and 507 bios? or am i dreaming?

I'm using noctua-nu12 air cooler

I need 500fsb 8x500 to get there.

Is ddr2 800 fast enough to get 500fsb?

Well, you can only use 1.575V as maximum if you want to run it long-term.
Unless you're aiming for a Bungholiomark.

Any DDR2-800 rated 4-4-4-12 will get you 500Mhz easily.

Getting 500Mhz isn't as simple as Anandtech portraits. To be abosolutely sure you have to replace the thermal pad with paste, remove the ASUS logo plate on NB&SB heatsink then add a 40mm fan.
And to have any voltage beyond 1.45V stable you have to perform a simple droop mod shown at VR-Zone.

Also getting 4Ghz isn't just about keeping temperature cool, you have to get it below a certain level before 4Ghz will work stably.
4Ghz is possible, but only under careful guidance.

if i run it at 1.6 will cpu last 1-2 years ?

i will AS5 northbridge , dont think i can fit fans on the northbridge as the noctua overhangs and fan be too high, if i can i reckon i can raise the nb voltage too if it take it

is this absolutely droop necessary to take it over 1.45 im sure i seen people selecting 1.5 from the off with no mods

im crap at soldering dont trust myself, i see you can do a pencil mod on the p5w dh , where are the mods located to do on the p5b?

i like to do the vmch mod thats the northbridge, if i can really cool it good

 

[markymoo]

you ill informed look again

pencil mod for vmch hehe

 

[markymoo]

That's for P5WDH, but then again it could be similar for P5B. (965P vs. 975X PCB)
Anyway, you'll still need a pot in order to fine tune the voltage.

you wrong a pencil mod will do it yet again lol

the p5b pencil mods are coming lol

 

[markymoo]

wrong again!

here is the voltage mod via pencil

shhhhhhhhhhh

you are dangerous

stop dissing wusy...

@ wusy, this guy is far from serious. if he went through any serious forums, he'd know that nobody has got 4ghz stable with a 6400 on air.

 

[markymoo]

how is it you swear it cant be done yet i find it in 5 mins. whos wasting the time here what big deal is it where i got it from. thats one of many places.
im just glad i didnt listen to you thats all. thanks for trying

stop dissing wusy...

@ wusy, this guy is far from serious. if he went through any serious forums, he'd know that nobody has got 4ghz stable with a 6400 on air.

a few have got 4ghz stable. thats why i asked in this first place.

so running prime95 for 24hours is not stable ? duh

im not the one putting out disinformation

If he has all the answers to his own questions then why is he wasting your, and everybody elses time?
