Please Help with RAM problem!!!

[styga]

Hey guys I have isolated the problem with my ram being is that for some reason they are only coming up as 4 GB per stick rather than the 8 GB they actually are. Using G.skill RAM 2x 8 GB sticks, Gigabyte 990FX-UD3 mobo. If someone can help it would be greatly appreciated.

Whats ur os? 32bit or 64bit?

 

[alyoshka]

Post the exact Model Number of the RAM.
Isn't that the Gigabyte GA-990FX 'A' -UD3 mobo?
The MSL (Memory Support List) or QVL seems to support only one 8GB module , and that is Samsungs M378B1G73AHO. Though the RAM Model number would still be appreciated.
Other information that maybe asked for is What CPU and PSU?
ANy changes that you made in the BIOS?
Has this been happening from the very first moment or did it recently start?
Have you checked in the BIOS as to the Installed RAM?
Which slots have you populated on the Board?

 

[styga]

OKay here we go..
CPU- Phenom II x4 975T BE
GPU-HD 6950 2 GB
PSU- Corsair 750w
RAM- G.skill RAM 2x 8 GB 1333 speed

I have used slots 1 and 2 to support dual channel
No changes have been made in the BIOS
This happened right at the start
Yes its the 990FX-A-UD3

Ok, now I want you to tell me again, are you using the Slots that are side by side or are you using alternate slots? Since you haven't mentioned the name of the slots, which are DDR3_1,DDR3_3,DDR3_2 & DDR3_4 and are precisely in that order. Starting from the outer edge towards the CPU.

 

[styga]

Nope DDR3_1 and DDR3_2 they are separated but have the same color.

 

[alyoshka]

Good, remove the RAM sticks and put them in DDR3_3 and DDR3_4.
Boot straight into the BIOS and check the amount of RAM it Shows there, post the result here.
Also post what Voltage they are running at.

 

[styga]

okay will do be back in a few

 

[styga]

Alright went into BIOS the only thing I could find was extended memory which read 8190 and for the voltage I found DRAM voltage- 1.5v

 

[alyoshka]

Since the BIOS itself is showing only half of the total memory available.
Or Do you have a 4GB stick lying around?
Another thing would be to try just one Mem Stick at a time and see if it shows up to it's full capacity in the BIOS.
Check and let me know again with just one stick in Slot DDR3_1.
Try them both one at a time and check in the BIOS for each ones shown capacity.

Or then Finally, you're left with no other option but to test the RAM sticks in another rig....

 

[styga]

I've already tried that no matter what each one is idependently a 4 gb stick for some reason unknown to me.

 

[alyoshka]

Are you sure that's a 8GB Stick, I want you to read the Product Number off one of the RAMs and type it here, not the new egg link.
Just to reconfirm.
I know it's a pain, but, lets not leave any place for doubt.

 

[styga]

I've read the sticks and they say 8 GB on them and then a lil further on the RAM stick 2x 4gb

 

[styga]

Each one says that they are individually 2x 4gb = 8gb per stick

 

[styga]

I think I am rather dumb because it might have come as a kit thus meaning that they are 2 4gb sticks to = 8 gb overall, although the confusing matter is that each stick says 8 gb on the stick itself

 

[alyoshka]

@ x4gb means 2 Sticks each one of 4GB.
