DRAM E.O.C.P Not working
« on: February 06, 2012, 11:36:46 pm »
Hi running 990fxa-ud7 MOBO with corsair vengence ram had computer running smooth since i built it few months ago used DRAM E.O.C.P function to run RAM at its rated 1600 no problems what so ever

Now hear is my problem i updated BIOS yesterday now i cant get the RAM to run a 1600 computer wont even post. From memory i tweaked something but cannot remember what i also reverted back to my original BIOS but still no luck any help would be very much appreciated

P.S i have tried to use both original BIOS and BETA F8a BIOS with the same result i get the message (boot failures accured due to overclocking) i am almost positive its just a setting i have overlooked

Here is what I had to do in the bios:

Set DRAM E.O.C.P to x1600
Set Memory clock to X8.00
Set system voltage to auto

Then had to go into the DRAM settings and manually set the timings to match the BY SPD column. under the AUTO column they are 1333 mhz settings and for some reason the auto wont change them to the 1600 mhz settings which are listed in the BY SPD column, you have to do it manually
