Personally, I always update any board I get with the latest (non-beta) BIOS available. I've never had any problems yet.

I'd have to say that the P5B Deluxe is one of the best boards I've ever used. The only problem I've have with it is the lack of dividers for RAM. I'd like to be able to have the option to run my RAM at a lower frequency than the CPU FSB, but with this board, it appears that the lowest divider is 1:1 .

The P5B Dlx doesn't have any dividers other than 1:1?

It may depend on the type of heatspreader as well. Just get some active cooling over those sticks and you'll be golden.

Thank you.

One of my favorite OC's is 389fsb=3501Mhz @ 1.3875 v. Memory at 2.25 ddr2-1167 5-5-5-12 or ddr2-778 3-3-3-6. All other voltages are set to auto.Enhanced speed step and other things are disabled. I will see the exact settings in 15 mins, as I am about to go for 3.5 now. Maybe consider, dropping to 8x multiplier 435fsb=3480Mhz ddr2-1088 at maybe 4-4-4-12.

You cant select a divider less than 1:1. IE, you cant have a 400fsb speed and ddr2-667, ddr2-800 is the lowest option available




Ooops, sorry about double post, I meant to edit my last response

How do you figure DDR2-1167 or DDR2 778? If your FSB is, for example, 400MHz, isn't your RAM then 400MHz (DDR2 800)? Or can you manually set it or something? Also, is there really only one divider on the P5B DLX?

But you can have your RAM working faster than the FSB? Isn't that pointless cuz it would be bottleneced by the FSB?

Edit: I ask because i'm interested in this board.

Well, yeah, sorta'. You can, supposedly, make your RAM run faster than your FSB (although I'm not sure how that would help performance..?) but you can't (afaik) set your RAM to run at, for example, four fifths of your FSB (5:4 FSB:RAM), or half the speed (2:1 FSB:RAM), or at least I (and several others) can't find a way to do it...

Somebody correct me if I'm wrong here, I don't want to spread false information .

K, there are 1:1, 4:5, 2:3, and 2:1 dividers.

I was using a fsb speed of 389, 389fsb with a 2:3 = ddr2-1167 The same with a divider of 4:5 389 fsb with 4:5 divider = ddr2-973, with a 1:1 divider=ddr2-778.


DDR2-778 = 1:1
DDR2-973 = 4:5
DDR2-1167 = 2:3
DDR2-1556 = 2:1


^^^^^with using a fsb speed of 389.







Edit: read this thread, devolop your own opinion if there is an increase in performance. I saw a 8k difference in AM3 and maybe a 1% difference in fear byt have ddr2-1167 5-5-5-10 vs ddr2-778 3-3-3-9

Ah, ic. So basically all those dividers do is just run your RAM faster than the FSB.

Yep, afaik, that's right. It's not so bad though. My DDR2-667 will run at DDR2-800 speeds with a little extra voltage and a few looser timings. 1:1 is best, as mentioned above; it's just nice to have the option to use a divider that slows your RAM down vs the FSB, to take the RAM out of the equation when overclocking your CPU.
