Help me overclock: e6400, ddr2 800, and Asus p5b.

Don't change the cooling setup. You can, if you want to do it, remove it, clean it off really nice and put AS5 there instead of the stock stuff. I didn't and it never goes above 40c ever. There's no need to increase the cooling on the NB.

ok, i was hoping that would be the reply.

I should note that I booted into windows at 510fsb on my P5B Deluxe with everything stock, but at 1.45v on the NB and it was 40c. I don't know a way to stress the NB more than overclocking it and pumping voltage into it.

Can someone just please tell me how i can set the memory to a 1:1 ratio all the time when ever i change my fsb in the p5b asus board so as i change the fsb 380x8 etc it seems to change the memory frequence itself am i suppose to disable something.

Thanks

You can't lock the memory. It ramps up with your FSB. The settings shown are the REAL MEMORY SPEEDS.

I too am confused about memory ratio on the p5b deluxe. Am I right to assume the bios is expressing the resulting memory speed instead of the ratios? So as I up the cpu freq. and the bios keeps updating the memory speed from 800 and up then I should select the next level down that is now closer to 800? In other words, if I choose a memory level that is <=800 my memory will be at 1:1?

Sorry but I just can't get this straight!

ok, basically whatever the BIOS says for your memory speed is what your memory will run at. If you set fsb to 400 you will see these speed possibilities...DDR2-800, DDR2-1000, DDR2-1200, DDR2-1600

If you select DDR2-1000 you run 5:4 ratio except it doesn't show. If you select DDR2-800 it's 1:1. It shows the actual running speed of your memory, not the ratio.

@crazymike

raid 0,1,5 and 10 can all be run from the p5b using the ich8r controller. the jmicron controller is only for external raid. dont use jmicron. make a raid ich8r floppy using your asus cd or use nlite(im in the credits) to intergrate your raid drivers into your xp cd so you wont need no floppy.

dont say raid 0 cant be done im running it fine.

@kandor

the memory has to be at a certain speed to keep data flowing upto the cpu. you have to lower the memory under its default speed if you going to overclock otherwise when you raise the cpu the memory will be overclocked way behind its possible potential and the pc wont boot. so the minimum and maximum benefit is setting the memory on 533(1:1) to give you your highest oc potential. this way your memory wont restrict your overclock. so the cpu will hit a heat issue before that happens.

266 fsb = 533 memory
333 fsb = 667 memory
400 fsb = 800 memory
500 fsb = 1000 memory
600 fsb = 1200 memory you wish

Thanks for the info - much appreciated.

Thats what I thought but wanted to be sure, I tried a few basic overclock with my setup last night and realized it's way more complicated that overclocking my x2 system. So research and more research.

my specs:
P5B deluxe wifi-ap
e6400 (week25)
2gb kit OCZ Platinum ddr2 800
Nvidia quadro fx1400
zalman cnps9500 LED with as5
5 x wd2500ks (250gb sata3.0 drives)
1 x samsung 250gb sata3.0 drive (leftover from other system)

@markymoo: when you say 533 = 1:1 do you mean if your ram is 533 speed?

Also, about raid on the p5b deluxe. I have 6 drives on the intel ICH8R, 2 are a raid1 for my C drive and 4 are raid5 for data. But I'm sort of pissed about the intel ICH8R, the documentation CLEARLY states that the ICH8R support upto 6 drives for raid5 but when you setup the array it says "please select 3 or 4 drives" and never allows you to select more. (btw I hadn't planned on raid1 on my c drive but I sort of got stuck with an extra drive) I wanted 5 drives in my raid5.

Thanks,

Kandor

I posted my BIOS settings Here

you may want to try this and see how it works for your overclocking.

Cool, I'll check it out -thanks.

Also - I'm just starting to figure this out. My ram is ddr2-800. The stock cpu freq. is 266 so if I leave everything alone my fsbram ratio is 2:3 or 266:400.

Another question: the ocz product page for my platinum dual channel kit says that it's 2.1v and 4,5,4,15 so I've gone and forced those settings in the bios - good idea? or not...

Thanks,

Kandor

Yes always set the standard recommended settings in the BIOS. If OCZ says do it, then it should be able to handle it.

Thanks cmdrdredd,

I've managed a successfull overclock, ortho runs ok, but prime95 errors after 5 minutes so I still need to tweak some stuff. I think I'd be happy with the temps if I didn't have core showing me 60-62 degrees. But that is only with torture tests, my renderer which runs both cores at 100% runs about 4-5 cooler. What do you think?
