ASUS P5B-Deluxe; Problems & Fixes

[chuckbam]

bios is 1004
now i put 90 pci-e and i put higher voltages ( i didnt need them to be stable) and everest marks @X16. I launched a game in which i had sound corruption and lag and it seems to be fine for the momment. I will be testing it.
PD: i put the latest bios 1226 and i had the same problem with the pci-e X1 and i put back this old one because i cant boot past 440 FSB.

That may be the problem. That is an old issue that has been fixed by a bios update. I would go with #1219 or 16
bios 1226 has an OC problem.

Anyway, updating to 1219 is worthly apart from that?

Let's be clear. ASUS bios never solved the PCI-E x1 issue, this is not true. It is a hardware limitations fixed in new PCB releases. I tested two P5B Deluxe, same C1 revision, one old, the other new. The new one, doesn't have the problem. Note also taht it is not a NB revision bug, as many C2 boards also have the problem. It is suerely a problem in the PCB design or elsewhere.

The only thing causing it on those defective PCBs is the NB voltage above 1.45v. Starting from 1.55v it happens, this is a well known issue since the begining. I tried all bios versions, it won't solve it. The only solution is a poweroff by removing the electric plug completely. Any soft reset will give the error again.

My two cents, live with unplugging the power cable when you reboot, or RMA it, you could get a new PCB bug free

I agree about your fix. But, I have not had the 1x PCI-E issue in over 8 months.

Johnny resumed what I have experienced too quite well......any soft reboot on a crashed vga or other will invariably give a x1 pcie.....unless you have a very low multiplier (high fsb if you a re looking to OC max) or low Pcie........only solution is to cold reboot after a long wait(sometimes even haveto take out the pcie devices )

our friends at BE have discussed the subject quite extensively too.

BTW with my setting I've worked out the pb too and never ecounter it.
