How to restore previous RAM settings

[UPSDW]

Hi all, this is my first post on the corsair website and as i suppose many are, it's a problem related one.
After changing the RAM speed in the BIOS from 'auto' to '800mhz' -as i feared the high 1066mhz speed was causing the instability issues i had been facing- the PC refuses to POST.
I've tried all the recommendations for POST failures i could find online and none of them have provided a fix.
With no ram sticks inserted the board still makes a continuous beep so i'm hoping that the motherboard hasn't died.
Any tips on what i should try next? I've already reset the CMOS and removed the battery etc.

have you tried a single stick first?
most MBs use 1.7-1.8v on reset so if your RAM needs 2.xv you may need a cheapo stick to get into the bios.
you can also try holding down DEL during boot.

I've tried using just one stick of my dominator ram and that hasn't made a difference. I guess i'll have to borrow a stick of low speed ram from someone. Will a 512mb pc3200 work on my MOBO?

You may have to reset the BIOS with the CLRTC jumper.
Please make sure you have the latest MB BIOS and load setup defaults and set the Dim Voltage to 2.1 volts ( +.3 Volts with Gigabyte) and then set the timings manually to the tested settings for the specific module you have and then test the module/modules one at a time with www.memtest.org! If you still get errors, we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure. In addition, with some MB's (mostly ASUS) you have to disable legacy USB in the bios when running any memory test.

I've managed to get my system running again after leaving it untouched for 24 hours. It's back up and running as usual and i've set the voltage at your recommendation of 2.1v. If i have any further problems then i'll set the timings manually. Thanks to all for your help.
