EIST Option Disappeared From BIOS Setup, GA-X48-DQ6

[Rusty_Shovel]

I have been using the Dynamic Energy Saver utility for about 2 months without any problems. Yesterday, after I booted to Windows, DES did not start and instead there was a dialog box which says something to the effect of: "in order to use DES, enable C1E and EIST in the BIOS". This was strange because I knew that both were enabled already. When I checked the BIOS, however, I found that the option for "CPU EIST Function" was not disabled, but had disappeared entirely! I flashed to the latest BIOS (F7B) today, to see if that would fix it, but that has not changed anything. The only thing I can think of is that the motherboard has stopped recognizing that my CPU has EIST available. Any ideas? The CPU is an Intel E8400.

Lol, funny stuff.

Did you overclock that e8400? If you did, set it back to stock. Speedstep is known to behave strangely when overclocked.

Never overclocked it, it's plenty fast as it is (for my mundane purposes). I guess I should check to see if the various settings are where they should be.

I have the same problem here. I have a gigabyte GA-X48-DS4 and a E8400 as well and the energy saver was working fine, but after i updated the thing (it kept asking if i wanted to update so i did) it didnt work anymore. I checked the bios and the EIST function was gone. This is really weird. Did you find anything interesting already?

Same problem here, Gigabyte DS4 X38

and the sleep mode doesn´t work (i must turn OFF and ON the computer power supply) 😱

Once in the BIOS Hit CTRL+F1 to show the advanced BIOS settings.. you will see Enhanced Halt State (C1E) and EIST Function once again.

im also having the same problem. EIST has disappeared completely.

i tried Ctrl+F1 and it did nothing. did this work for anyone else? im not sure what it was actually supposed to do? what is it a shortcut for?

has anyone had any luck fixing this?
