Advice needed: Upgrade Memory

Hello everybody,

About two years ago I assembled the following machine:

Motherboard: Gigabyte GA-P55A-UD3 Intel P55 LGA1156. (http://www.gigabyte.com/products/pro...px?pid=3242#sp)

CPU: INTEL Core i5-760 2.8ghz quad-core (BX80605I5760)

Memory: G.Skill Ripjaws DDR3 4GB Dual Channel 1600MHZ CL7 4GBRM

Graphic card: SAPPHIRE TOXIC Radeon HD 5850 1GB Video Card 100282TXSR

HD: half a year ago I switched to: Crucial 64GB M4 SSD SATA3 6Gbs - 2.5 in (CT064M4SSD2)

I have now decided it's about time to use my 2 free RAM slots in addition to my "original" memory. I just bought this: G.Skill Ripjaws 4GB 2GBx2 DDR3-1600 F3-12800CL9D-4GBRL

However, after installing it the computer won't come up. What am I doing wrong? Is it because the new memory is not suitable with the old one, or is it just because I'm installing it wrong?

Thanks!

    You may need to reset the firmware settings when installing memory that pushes the capacity above 4 GB. Consult your motherboard manual on how to do this.

    Hi,

    thanks for the answer.

    What do you mean by "reset the firmware"? it's the latest one... The MB can't accept above-4G memory by default?
  3. Reset the CMOS memory the right way as is described in the motherboard manual using the clear CMOS link with the power cord unplugged.
    And when the battery is out, press the power button to discharge all the electricity from the system.

  4. I think he meant the BIOS.

    By reset the firmware settings I mean "reset the BIOS" or "reset the CMOS", those are just unfortunately common misnomers so I avoid using them.

    Some motherboards have a pushbutton on the board which will do this, others require that you move a jumper. Consult your motherboard manual to find out how.

    Some motherboards have problems with going from <=4GiB to >4GiB. It's a compatibility issue with mapping various other real addresses into the virtual address space. Once the settings are reset it should remap everything properly.
  6. Thanks guys, I'll try it out.

    I knew it, not the first time I've seen that with the Intel 5 series chipsets. Glad you got it working
