Hello ,I have 8 GB of ram but my system memory shows 8GBram (4GB usable ) so I went into bios checked system memory it shows 4094 gb ??

I tried taking out the ram switching it but that didn't change anything , any ideas how to fix this ?


note - I recently went from windows vista 64 bit to windows 8 64 bit


motherboard - maximus formular 111
ram - corsair dominator


I don't know much about computing so please try to keep it simple if possible step by step walk through

Thanks n advanced :)

Hi, Try unplugging the power cord and removing the CMOS battery for few minutes. Look for a video on youtube if unsure how to remove the CMOS battery.

Check in msconfig / Boot / Advanced Options. Maximum memory has to be unchecked.
Also in BIOS /Advanced Chipset settings / North Bridge, Remap Memory has to be enabled.

both of these are as they should be, still didn't fix the problem I think my bios is out dated but the only updates are for windows vista / windows 7 but im running windows 8 not sure if that has any cause to the problem

bios is not os depent it not a driver. the last bios file for your mb is Version 2202. if your bios is less that that download the file to a usb stick do into the bios and use the mb bios updater tool. if the memory still shows 4g you may have a bad memory stick or a dead ram slot. take out both dimms. try each dimm by itself. if you have a bad dimm them one of them wont read/system wont post. if you have a bad slot in the mb moving the dimm to another bank may work. the issue to is if the ram is 2 sided ram the mb may be only reading 1/2 the ram.

SMORIZIO thanks for your help, I pulled out all the ram tested it individually it all worked

then I reinserted ram firstly into red slots ( 2 sticks ) and then black slots (2 sticks ) turn pc back on

and all ram is now present.

Strange thing is I pulled out the ram yesterday and switched it around but it didn't solve the problem but today is all good ??

only thing I done different is place ram as pairs in each colour slot.


My bios is still 2104 don't think I will update it as im not comfortable with that process in the past I used auto update but now that software is not compatible with this op system.

PROBLEM SOLVED :)
