ASUS P8P67 Deluxe Cold boot black screen

[ConMac]

I just upgraded the BIOS from v.1003 to v.1305, I was having the double POST issue. Now when I cold boot, I get a black screen, I have to cold boot again to get the message that the overclock failed, press F1 to continue to get into the BIOS. When I go into BIOS it says that my target CPU is 4.2 GHz. I did make the mistake of trying to OC using the AI Suite with the old BIOS a month ago. Now I just want to go back to the stock speed of 3.3 GHz for my i5-2500K. I'm using 2 x 4GB G.Skill Ripjaws 1600, which they say is compatible with this MOBO. Under AI Tweaker, I have it set to XMP. How can I accomplish this? Any help would be greatly appreciated!

overclocking failed is RAM, this goes back 5 years at least
try one stick of your RAM
the new bios made to be more compatible with dif brands has now made yours less compatible
First thing I would do is cmos clear, flash 1503 with bios set at failsafe defaults
See what happens.
Uninstall AI Suite
If still black screen, then flip up TPU switch on mobo, give it time to do its thing, reboot twice and see if that can find workable bios config for you.
Even tho you set to XMP, manuallly enter the all values anyways
If that still fails, you can go to superbiiz and buy Suoertalent 4GB sticks by listed dram chip
Hynix
Spectek
Micron
Samsung
Elixir
One of these will work for you - on my board its (cheap) Micron
Remember - its not the RAM brand, its the DRAM brand.

Can you load default settings in the bios and then f10/save?
CMOS reset or taking out the battery for a minute will clear the bios settings too.
Uninstall AiSuite on your HD and it won't be there to boot and you can reinstall it.
Enable "wake up from PCI-E" to eliminate the double boot issue.
XMP profile is under the advanced bios not simple bios interface.

Thanks guys! I'll try clearing the CMOS first, then go from there. Cheers!

Hey, before you do anything would you put this on a mem stick and boot to it and seei if it passes.
I always suggest this, but everyone ignores it
System doesnt have to be bootable, you just have to get into bios to reset USB as first boot
