I just changed motherboards to a DFI DK-790FXB-M2RSH. Great mobo has lots of o/c options (although half of them i have NO idea what they do/mean).

 

As alot of the terms in the bios for memory timings have changed (and the sequence has changed too), is there any1 that can advise me on subtimings?

 

I know that the first 4 should be 5-5-5-15, but there are about 10 other subtimings that i have no idea on where to set them (even if it's a base guess and i can try adjusting up and down from there to find stability).

 

Problem is with this board it doesn't seem to have an EPP setting (that i can find) so i am not trusting the SPD/auto settings that are placed (as i'm seeing numbers that i never saw on the GBT MA790FX-DQ6 from the memory section.

 

Below are memory settings i will put in brackets what i have selected so far.

MCT Memory Timing ...... Sub Menu [Press Enter ]

MCT Memory Timing ...................: [Auto]/[Enabled] {Enabled}

CKE Drive Strength..................:[1.00x][1.25x][1.50x][2.00x]

----------------------Dram Configuration--------------------------

DCTs Mode...........: [Ganged]/[unganged] {Ganged} *Don't really do many multithreaded apps only game so Gnaged it is.

CKE base power down mode {Enabled}

CKE based power down......: [Per Channel]/Per CS] {Per Channel}

 

If any1 could please give me some advice on these settings it'd be GREATLY appreciated.

 

Also another note... i used to be able to run this @ 1160 on my gigabyte ma790fx-dq6 is there any reason that i wouldn't be able to run these settings on my 790fxb? surely i would be able to as i have ALOT more control over the settings now (drive strength settings etc).

 

Also is there any chance of pushing higher mhz with looser timings?

 

Any advice would be greatly appreciated :)

Please make sure that you have the latest BIOS version and then load setup defaults and set these settings:

Memory Frequency: DDR1066

Memory Voltage 2.1 Volts

2T Mode.................: [Enabled]

CAS Latency Time.....................: {5}

Precharge delay (tRAS)...............: {15}

DRAM RAS# Precharge..................: {5}

DRAM RAS# to CAS# Delay.............: {5}

Bank to Bank Cmd (TRRD)..............: {Auto}

TRC..................................: {24}

TRTP*................................: {Auto}

Write Recovery (TWR)*................: {5}

 

All other settings should be left at Auto or BIOS default.
