P5B Deluxe: BIOS screens for maximum overclocking success

[mrt2]

I've had this board since January and have had such a nightmare with vdroop, FSB issues and issues with my pci-E video cards running at 1x... I personally don't think it's too much to ask for a product without so many glitches... ANYHOW back to my issue, I currently can't boot... AGAIN yes AGAIN... usually when I have that issue I just do the switching RAM trick, but it's not working now and I don't know what I'm doing wrong. What's the best way to do the RAM switching trick? I usually put generic RAM in it... it boots fine, then I change the mem voltage to desired (usually 2.15 or 2.25) then save/reboot... wait for it to false start two times in a row and then either flip the switch in the back or hit and hold the power button during the real startup until it shuts down again... and switch out the RAM... I've been doing this for like over a day now and I still can't get it to boot. This happens to me like once a month... I'll come in the room and the PC is not responding so I reboot and can't get it booted up again without switching RAM... Does this happen with ALL RAM that require more than 1.8v or is it just certain brands/kinds of RAM? Currently I have OCZ platinum 8000... anyone know if this RAM has a life time warranty or good customer service so maybe I could ask them to switch out my RAM? Or is there a brand of RAM I should get instead of this? Please help, as I need my pc for my job. Thanks in advanced guys.

Ive had this mobo for some time now and love reading about how you lot like to push the limits of the P5B.

I finally got around to playing with my settings,here is a picture of how far i got i no its no where close to you all but im new to this.

Any new beta bios folks ?

Are any of you guys with 2:3 in the mem ? Any problems ?

Some times when Saving & Exiting the bios, using 2:3, it freezes and doesn't restart ! But the changes ara all saved.

Any idea of what it is ? Could it be because of the 2:3 memory divisor ?

My 24h/day system is like this :

Can someone explain the result of the FSB strap change at 401 on these boards?

What happens to what timing signals (RAM frequency) that is different at an FSB of 400 vs 401? If possible could you use my FSB of 400 running my memory at 1:1 (DDR2-800, 400MHz to memory) and tell me what happens to what numbers if I bumped to 401 (I think that's the 'strap change')?

Thanx in advance, Skip

It would take along time to explain the 'Theory.' Each seccessive strap is slower than the previous one. Check out the following link;that will explain it better than I can.

Thanx, read it... good write up. Everything else I've read on P5B-Deluxe and P5B-E says the strap change appears to be at FSB=401 instead of 400. Maybe a newer BIOS.

I got a good, fairly short, explanation of FSB strap HERE.
