8gb ram installed, only shows 3.95gb usable. Pics inside

Corey005 · Jun 22, 2014

I installed 2x4gb of ram, but it only shows that 3.95gb are usable when I go to control panel > system. In CPUz it shows that there is 4gb in each channel. I'm running Win 7 Ultimate x64. I've already looked in Msconfig to see if it restricts how much ram will boot with the system and it shows that it all boots when the system boots up. http://gyazo.com/eeab6d71c760f1bb58f663c208755f52

How about some more info? What MB and what is the memory kit model?

EDIT:
Looks like maybe only one stick is working. CPUZ says single channel? Are the sticks in the correct slots?

sounds like 1 bad stick, bad mobo, or bad slot in ur mobo. or u don't have one seated compleaty.
pull both sticks, put um in the other slots on ur mobo

Ok just tried reseating them and this was the outcome: slot 1 both worked in it. When I tried to put just 1 stick of ram into the 2nd slot it would not display anything and my power button would be fading in and out. Does this mean that I have a bad slot? If so how can I fix it? Btw it still shows that I have 8gb installed
EDIT: I was just thinking, does the 2nd slot of ram go towards the hardware reserves?

The mobo is an MSI A55M-E33

The memory I have is http://www.newegg.com/Product/Product.aspx?Item=N82E16820231655&cm_re=g._skill_sniper_2133-_-20-231-655-_-Product

ur mother board has a bad slot, 1 stick should work in any slot on the board, no the 2nd slot is not designated hardware reserve
all slots are for main ram for ur mobo/proc. hardware reserve, is setup by ur os.

windows 7 n up will dynamically assign hardware reserve, as needed, even with hardware reserve, 8gb shows as 8gb hardware reserve doesn't take away from ur installed mem

You might have to OC the cpu some to be able to use that memory at the advertised speeds if at all.

The 760K is rated at up to 1866MHZ memory.

The number of controllers: 1
Memory channels: 2
Supported memory: DDR3-1866

On top of the CPU, you probably have a bad MB that does not read the memory correctly in one slot.

Try going into bios with one stick in and set up the BIOS plus the memory voltage to 1.6V plus the memory timings and speed. Enable XMP Profile1 in BIOS and see.

Corey005 · Jun 23, 2014

Tried that and nothing happened spooky2th, should I just get a new mobo? And I currently have the ram set at 1866 MHz

It's looking like that you need another MB. RMA the board. Should have a 3 year warranty or if it is within 30 days, send it back to where you got it.

Corey005 · Jun 23, 2014

Yup, just got an RMA. Thanks!
