Hi all,

Apols if asking this in the wrong place.. It's been a while since I had my PC built and more and more I'm needing more memory for my games. But what can I upgrade to?

I currently have 4Gb in 2 of my 4 available slots:

2x DDR3 Corsair 2133Mhz CMX4GX3M2A1600C9 2Gb

I've dumped some of the system information below (probably too much) but I would really appreciate advice!

Thanks!!

Darren

Go to Crucial and use their scanner. It will teel you what your options are. Whilst you can get cheaper memory, you'll not get better service.

Thanks Marvin.. looks like I am stuck with a max of 4Gb for my system according to Crucial lol

  alanrwood 10:22 16 May 14

That would be unusual nowadays. What is the exact model of your motherboard. If not sure run Belarc Advisor.

Maybe Crucial is saying this because you only have 4 slots and two are filled with 1GB sticks. You may be able to fit for example 4 off 2GB sticks to give 8GB (ie discard the existing 1GB sticks).

Remember though that if you are running a 32 bit Windows it can't use any more than around 3.4 GB anyway. To use more you must be running a 64 bit version

Hi Alan,

I'm running a 64bit system and currently have x2 of the following installed, with 2 free slots:

Memory type DDR3 Module format UDIMM Manufacturer (ID) Corsair (7F7F9E0000000000) Size 2048 MBytes Max bandwidth PC3-10700H (667 MHz) Part number CMX4GX3M2A1600C9
Number of banks 8

Motherboard: Mainboard Model H55M-UD2H (0x0000023F - 0x0287A9D0)

Is that about right? Thanks again!

If this is your motherboard CLICK HERE it will support up to 16GB

  hastelloy 14:55 16 May 14

Crucial usually give you the option to keep what you have or to start from scratch. I'm puzzled by their response to your query.

  darrenford1111 15:04 16 May 14

Thanks everyone for your kind and swift help!

I'll be buying another 2x of the same RAM and also discovered I can upgrade to a 3Gb graphics card too!

Have a great weekend all!

If you have used Crucial's RAM notation, be aware that it does not tell the whole tale.

I can't believe that Crucial would pass up a sale if they could. So, why not try Kingston's RAM Checker
