Adding ram to my pc

rvbuijtenen · Mar 5, 2014

Today i bought an 8GB stick of RAM, and tried to install it. Everything on my computer is detecting a total of 16GB now, except when i look for properties in windows, it says memory:16GB(8.00GB usuable)

System specs:
ASUS M5A99x EVO motherboard
AMD 6-core(dont know exact product)
2x4 DDR3 kingston 1333Mhz
newly added 1x8GB DDR3 Kingston 1333mhz
samsung SSD 120GB
Caviar Blue 500GB hdd 7200RPM
HIS Radeon HD6840
Windows 7 64bit

the 2x4 GB are in slot A2 & B2, and i put the 8GB in slot B1.
also, my motherboard is in dual channel mode

does anyone know how i can get my system to recognize the new 8GB memory stick?

ps, i havent tried switching ram slots, those things are fitting in so tight, and with the limited space because of my additional CPU fan, i can't pull them out. i don't want to remove any components either, since i think i'll mess stuff up when i reassemble it.

well, first make sure all your ram is working in your bios. also make sure it isnt reserving a large amount for bios or windows.

Check your motherboard manual. It may specify that the RAM can only be used in pairs. To find out what your CPU is, use a program called CPU-Z.

yup, your mobo is dual-channel architecture. https://www.asus.com/Motherboards/M5A99X_EVO/#specifications

better to put dual channel kit.. not 2X4GB + 1X8GB ???
get an other dual channel kit (2X8GB) instead of 2X4GB + 1X8GB

Check this topic there is quite detailed solution there: http://www.tomshardware.co.uk/forum/321581-30-installed-memory-usable

and yes, 2x4gb ram is faster cuz of dual channel.

Danbuscus25 :

so, thats means that it only accepts memory in pairs of 2?
also, i finally managed to get the RAM out after removing the GPU, and tried booting only with the 8GB in slot A1, and a red light started flashing and nothing happened, then i put the 8GB + a 4GB in slots A2+B2(where the 2x4 originally were) and right now windows says memory:12GB(8GB usuable) so its only using the 8GB stick, but requires 2 to be in place somehow. why is it still only 8GB? (Edit: nothing to see here, never said anything about the c-word

my apologies)

Danbuscus25 · Mar 5, 2014

so, because you do have 2 sticks in, it boots. but i guess it can only use 4gb from each slot?? idk why it doesnt say 12gb.

''i have a cracked OEM version of windows ''

ITS NOT A PLACE TO TALK ABOUT CRACKS! SORRY

rvbuijtenen · Mar 5, 2014

Danbuscus25, i have 1x8 &1x4 right now. Im 100% sure my mobo supports 8gb sticks since the manual clearly states it accepts up to 32gb ram with 4 slots. Also, 4gb from the8gbstick + 4gb from the 4gb stick? Im no expert but tht seems rather unlikely. My gues is tht its using the 8gb 1 & ignoring the 4gb. I think theres something in the settings tht limits my ram, even though i disabled ram limit in windows settings. Also tried booting with limit set to 16gb.

Danbuscus25 · Mar 5, 2014

well, by cracked, do you mean its normal windows but its not activated?

rvbuijtenen · Mar 5, 2014

Cracked as in windows thinks its activated(said so in settings) w/o paying for it or ever going through the activation procedure. Anyway, i was told i shouldnt talk about tht here, sorry for bringing it up

rvbuijtenen · Mar 5, 2014

Btw, cpuid detects the ram, bios detects the ram, windows detectsvit but says only 8gb is usable

Danbuscus25 · Mar 5, 2014

its weird that it wont boot with only 1 stick, but it will with 2 sticks but only use 1. idk whats wrong then.

Hello man · Mar 5, 2014

Danbuscus25 :

My MSI 970-G46 (great motherboard right!) does the same thing. I use 16GB right now, and when installing it it was quite a shenanigan.
