I have a Dell XPS 8500 with an i7-3770 whose motherboard was bricked by a Dell BIOS update. I've since purchased another board, but am having problems with RAM.
The original board had PC3-12800 RAM modules. From what I read, these modules (as well as the PC3-10600) should work. When I put them in the replacement board, I get 4 beeps, indicating a RAM problem. I've tried some Crucial brand RAM which was listed as compatible with this model and get the same results. I've tried a single module in each of the slots, one at a time.
The board does work if I use a PC3-10600 module.
I've upgraded to the latest BIOS and reset it to defaults. I don't see any settings in the BIOS that have anything to do with timing.
I can go ahead and purchase the slower RAM, but I'd prefer not to.
Is this board defective or am I missing something?
