Asus Maximus Extreme-Z not recognizing memory right

[pimpin-tl]

I purchased this ram: http://www.newegg.com/Product/Produc...82E16820145325 And the bios is saying it's DDR3-1066. What do you recommend I do to resolve this issue?

Thanks!

Go into the BIOS setting that allows you to configure your memory settings, choose the setting that makes the board follow the memory's XMP profile, and voilà! DDR3-1600 at advertised settings.

The reason the BIOS is seeing the memory at DDR3-1066 is that that's the default JEDEC setting for the memory to allow it to work on any DDR3 compatible motherboard. You have to change the settings to get the advertised speed, as mentioned above. Nothing wrong here.

I have this mobo too!

Trying to figure out why it doesn't let my cpu lower its voltage when the cpu is idling (it idles my 2600K at 1.6GHZ but 1.25V ).

I too have an issue with the default memory speed. I bought some DDR3-2133 sticks but the mobo defaults them to DDR3-1600.

Near as I can tell the mobo just randomly decides which SPD setting it wants to apply for your ram, because DDR3-1600 is neither the lowest nor the highest SPD entry for the dimms in my case.

I haven't found a way in the BIOS to tell it to use a specific SPD setting (complete with all the timings stored in that SPD). I have found where I can set the DDR3 speed (1600, 1800, 2133, etc) but I still have to dial in my own timings at that point.

If you figure it out please report back so I can find out too!

Damn! I just looked at the manual for your motherboard and while your BIOS sure is pretty, it seems to be lacking a lot.

I used Asus almost exclusively but for some reason went Gigabyte with my 2500K.....and while the BIOS is old school, it does access the XMP profiles in the memory and does drop the voltage on the cpu at idle.

Looks like Asus tried too hard with that new BIOS and just screwed the pooch in the end.

take a few minutes & view...

dimm a2 + dimm b2 populated

update to latest bios - 18xx beta available "&" update all asus/rog utilities

i have recently set-up m4e/b3 + 2600k + gskill f3-12800cl8d-8gbxm (4gbx2)

Well there has to be a way when it's one of the hottest OC boards today. Will post back once I figure it out.

OK, it may actually just be a case of information overload...ASUS packaged too many options all together in the BIOS and you have to navigate through a lot of stuff to get to the options you need for this.

OP - go into "Extreme Tweaker" in your BIOS, its the first option on the far left.

Then go to the option labeled "Ai Overclock Tuner" and select X.M.P. from the pop-up menu:

Then the BIOS should find, and use, your DRAM settings.

My BIOS was overvolting my 1.5V dram to 1.65V by default, even though the SPD settings specify 1.5V across the board.

Thank you sir. I actually was able to manually switch it to 1600mhz instead for now, but next time I reboot I will change it to that setting for now. Thank you!
