RAM problems

Recommended Posts

Hi all,

 

I am having a few issues with my ram, according to windows i only have 4gb (YES I AM RUNNING 64BIT) while cpuz recognises all 12. My system specs are; i7 950, ROG R3F, 3x4gb corsair 1600mhz 9-9-9-24, 2x 6970s crossfire.

Also apparently im in dual channel.

Here are some pics.

you need to type "msconfig", in the start menu search.

 

Press enter

 

Goto "Boot", then click "Advanced Options", then do Maximum Memory as high as it will go and then reboot.

 

(also activate your windows lol)

Mucho -

 

What's your dram voltage set to in BIOS? What is Corsair's recommended dram voltage for your kit?

 

While you're in BIOS manually set tRFC to 113.

 

Remove and re-seat your RAM modules.

 

If none of this works - pull your cpu and check for bent cpu socket pins.

Hmm, reseating the ram has made it go up to 8gb, nearly there!

Thanks for your help and any other suggestions would be great

You're welcome.

 

In my experience - most problems with Windows detecting all your RAM are caused by;

 

1. Outdated motherboard BIOS

2. Improperly seated DRAM module(s)

3. Lack of sufficient DRAM voltage

4. Improper memory timing settings (I've especially noticed on tRFC - Asus and MSI x58 boards - set too low with high amounts of memory can lead to "missing memory")

5. Bent CPU pins

6. Faulty DRAM module(s)

 

Good luck.
