x58 ud7 DONT START, only 88 CODE

If what you say is correct then the only way to prove whether the board is faulty or not is to clear the CMOS and then load BIOS optimised default settings with a basic configuration of CPU/cooler, RAM, buzzer and 1500w PSU. See what beep codes it produces and post back.

I cant do that u say, because the motherboard DONT START, only show me 88 code , i cant go into a bios and load bios default, THE BOARD DONT POST,with any cpu, any vga, any ram any nothing. Is any way to star the board with the BK bios, ( 2nd bios ) i remove the battery for 24 hs, and no way,

tks

You don't need to go into the BIOS to clear the CMOS memory. That is done without any power to the board at all. Remove the motherboard battery and leave for ten minutes at least.

i do this, but dont WORKs, any other way??? is possible swith to the bk bios?? maybe is bios corrupt, i dont know, i dont know what can i do

tks

If the main BIOS becomes corrupt the backup BIOS should take over automatically next time you boot. When you said you did this regarding the CMOS did you remove the PSU from the motherboard as well as the onboard battery?

[sangon]

yes, i remove the PSU from the board ( both conectores, 8p and 24p ), remove cpu, ram, vga, ALL, leave only the motherboard WITHOUT the battery for 24hs, and dont work, after 24hs, i put a cpu, all and show me 88 code, if i start the board with any hard plug ( cpu or mem or vga ), only the PSU conected, show me 88 code TOO

There is only one other thing to check as far as I can see and that is to make sure that none of the pins in the CPUI socket on the motherboard are bent. You will probably need a magnifying glass as they are extremely small but we have had a few instances recently so it is worth checking.

[sangon]

yes, i check the socket when this problem start, an it is PERFECTLY health, no pin bent!!! and no physical damage on the board, the board is perfectly ..

tks

In that case I can't think of anything else to try. I think you will have to RMA the board.

[sangon]

ok , tks for all

No problem, sorry I couldn't help more. Good luck.
