Help with mobo/ram... HALP!

[DanMikietyn]

Hi all. I hope you can help.

I've just build a new build, specs are as follows:

i7 4770k
Gigabyte z87-HD3 Motherboard
Palit Gtx 770 2GB
120 GB Kingston Hyper X SSD (windows/photoshop/steam)
1TB 7200rpm Seagate Barracuda HDD
1x 8GB Corsair Vengeance Pro 1600mHz (cmy8gx3m2a1600c9b)

and i'm running Window 7 Home Premium 64 bit.

I cant seem to get the system to see all 8GB of ram, only 4. I've tried all 4 memory slots, checked the bios (which doesnt say how much ram there is, just what frequency its running at) and looked at past posts here.

I cant seem to find the answer.

Any help would be greatly appreciated!

Thanks for your help in advance,
Dan

Make sure you have the latest BIOS, also ensure it is the Win7 64bit, check the stick itself and make sure it's a 8GB stick, in the BIOS, it should show how much DRAM is in each slot, also can right click MY COMPUTER, select properties and see what that shows, if it's a 8GB stick should show as such

i downloaded the latest bios from gigabyte, but it didnt really seem to install, just flashed up and was gone. not sure if thats done.

The stick is legit, my computer and all properties are shoing 3.9gb available.... i'm a bit stumped

Sounds like OS, positive it's 64bit version - didn't accidentally install the 32 - can look in MSCONFIG at the Boot tab>Advanced and see if Max Mem is checked - should be unchecked

 

[DanMikietyn]

yup, def 64 bit, boot tab memory, is unchecked.

I downloaded cpu-z and checked, it says my memory is running in single channel, not dual.

 

[Tradesman1]

That part is right, a single stick will only run in single channel - sounds like it's possible somebody changed the label on the stick from a 4GB to a 8GB label

 

[DanMikietyn]

wow... thanks very much for your help...

Changed the label lol xD. THats gay.
Maybe try it on another pc and see?

 

[DanMikietyn]

i've contacted the shop i got it from, hopefully i get to the bottom of this sooner rather than later!

 

[Tradesman1]

Hopefully Have seen where people buy DRAM, and chanfge the labels, then keep the 8GB sticks and return the 4GB ones with the label from the 8GB, then the stores never check them them and sell tham as whet they think are 8GB

 

[DanMikietyn]

well, its the only thing that this points to... unfortunately. ah well, i'll just soldier on with 4 gb for the moment

 

[DanMikietyn]

Actually, should it still run at 8gb if its in single channel? If i put another stick in, allowing it to run at dual channel, would i utilize the full 8gb in the stick then?

I was going to invest in another stick as it is...

 

[Yingda Wang]

Yes, it should still run at maximum capacity even at single channel.
Dual channel is faster but has nothing to do with capacity

 

[Tradesman1]

Does anything show the stick as being 8GB
