Updated bios, RAM causing system not to start

post #1 of 6
Thread Starter 
Posting on behalf of a friend.

He has an Asus P5QLD-Pro motherboard with a E6600 CPU. It has 4 ram slots which each contain a 1GB module. All ram is running at 800Mhz, however two modules have different timings (found using CPU-Z). His motherboard and Graphics card are brand new (XFX 5870).

Due to instabilities (freezing/crashing) in some games (just cause 2 and borderlands) we have been troubleshooting. Today I noticed that the bios wasn't the latest and updated it.

On restarting a bios screen popped up saying no OS on the optical drive or whatever, I entered the bios and changed the boot priority and disabled the onboard sound etc. Then when restarting the pc there is no output to the screen, completely blank. All fans are spinning.

For some reason I removed 3 sticks of RAM, and it booted to windows fine. I replace all the RAM and it gives me a blank screen. Dead. Nothing.

What could have happened in a bios update to have made this happen?

As an aside, does RAM of different timings causes stability problems?

Thanks in advance for all replies!

When you flash in a new BIOS all BIOS settings are set to their defaults.
You have to reset anything that was set in the old BIOS.

Also, the new BIOS may have different defaults for some settings or new settings where the defaults for the new settings don't work.

Thanks for your reply.

I realise the settings are set to the default. But I can't see how that explains how with one RAM module the machine can get to window, and with all 4 modules it doesn't POST (considering that it was working 'fine' before, although with some stability problems in some games).

Timings/voltage/whatever works for one, but 4 won't run at those settings.

Could be a memory controller issue too.

go into bios with 1 ram chip, Manually set the Ram timings and Mhz to the ones the slowest ram has. Increase Ram voltage to the highest one, one of the ram has.

Put in one ram at a time and then see where it stops booting.

Run Mem 86 on the modules individually...there could be a bad stick in the bunch and the new bios is just a little more picky...If the system was OC'd they may need more voltage. Try them all individually then in pairs then switch them around to different banks. Pair the same timing based ram in the proper slots. Set the bios not to use the Manufacturer timings? The last part is just random thoughts as I was typing.
