Help! Maximus IV Extreme-Z BIOS 3203

[fullinfusion]

Got a new bios for the Maximus IV Extreme Z68 installed for the migration of the 3770k cpu and there is a few different items now to choose from.

Maximus IV Extreme-Z BIOS 3203
1.Improve system stability.
2.Improve memory compatibility.
3.Support new CPUs.
* Enable support for Intel Next Gen 22nm Processor E1 stepping MP version CPU.

I get this new item to change but not sure if I leave it alone or not.

I noticed that on mine as well....not sure either. It says something about above 4G...I may see what mine does since I have above that assuming it means Gb lol

Just out of curiousity I tried it and when I got into windows I checked system properties to see how much ram was usable. With 16Gb installed only 13.XX was usable. Apparently it remapps the memory to be used with the PCI devices from what I've been reading. More or less here's what I've found and better explained .vs MS info lol (go figure)

If you have 4 GB of memory or more, you must have Memory Remapping [enabled] . Sometimes it also asks to what location, I just try each option until I can see all of my installed memory. I believe this feature was necessary because the orginal x86 architecture did not recoginze 4 GB much less a lot more.

And here's what MS says about it

Hope it explains a bit, I changed mine back to default setting as I like to use what I have when the app needs it

its for running xp 32bit

So your saying it should be off for 32bit?

 

[Fitseries3]

i always turn it off.

its for when you run xp32 and have 4gb ram.

it remaps the ram so that 32bit OS can use most of it.

not sure why they are still putting it in bios's but i suppose its not a bad thing

i always turn it off.

Will keep that in mind next time.

I dumped the latest bios as it wont boot up at anything more then X48 multi.
Was a pain but if you know how to use the flash back with out flashing the wrong chip your good to go

 

[Fitseries3]

ROG connect with flashdrive works perfect
