Help, my RAM won't work!

[Daniel95H]

Hi Community,

 

I got an issue with my PC. I started running out of RAM (even my Firefox needs about 1.5GB in itself) while playing some games (ex: Modded Minecraft) so I decided to upgrade from 8GB to 16GB by adding 2 more 4GB sticks to my existing setup. However, even though the RAM is detected by both CPU-Z and Windows 7 Professional Service Pack 1 64-bit (Though windows says only 7.99 are useable), I am unable to use them. Both are G.Skill Ripjaw, but I only found out through CPU-Z that the new sticks are a different make and that they are slower, use less voltage and are ranked as single channel by CPU-z. Currently CPU-z also says that my memory is running on single channel.

 

My specs are as follows:

Motherboard: AsusTek P7P55D (apperantly should support 16GB of RAM)

OS: Windows 7 Professional 64-bit (Service Pack 1)

Memory: 2x G.Skill Ripjaw F3-17000CL11-4GBXL (my old and current RAM) and 2x G.Skill RipJaw F3-12800CL9D-4GBXL (My new Cards)

GPU: Zotac Gefore GTX 650 Ti Boost

CPU: Intel Core i7 860 (Codename Lynnfield)

HDD: Toshiba DT01ACA100 ATA

 

Any help is really appreachiate, as I will have to try and send the RAM back if it is no use to me (Amazon 2 week policy).

 

Thanks in advance,

 

Daniel H.

 

 

Edit: After Scrounging the Web for more info on similar issues, I found that my Resource monitor Reports that it has reserved half of my memory for "Hardware" (8201 MB).

You need to run them at the same timings and frequency for them to work together.

I'm also like 90% sure the voltage needs to be set the same, too.

How can I set this up? because it seems my old RAM was actually better than the one I added (higher frequency). I'd assume by tuning the frequency the voltage should also decrease, but do you have any idea on how to tune these things?

higher frequency ram should automatically drop its speed to suit.

KK. Thanks MrJarhead. Still doesn't solve the overarching problem though , but thanks none the less.
