Can I install one (1-gig) memory stick instead of 2 match pairs (only have one) this is to replace two 256 sticks?will it preform at 1 - gig memory

You need to have 6 gigs of free dynamic ram.(Not including that used by the operating system and any other applications you have.

The way that memory is organised in a computer these days is usually in pairs or DRAM (dynamic random access memory) sticks which are matched. This allows the CPU to withdraw data from both memory sticks in the same clock cycle (DDR double data rate) which improves the over all speed of the processing.

So legal combinations over 4 gigs which will use the dual channel feature on your motherboard will probably be.

2 x 4 gigs sticks = 8 Gig DRAM
2 x 8 gig sticks = 16 Gig DRAM

Below is the minimum specification requirement.

Note: MINIMUM Faster CPU better graphics card and More ram is better.
CPU: Intel Core 2 Duo E8200 2.66 GHZ / AMD Phenom X3 8750 2.4 GHZ or better CPU Speed: Info RAM: 6 GB OS: Windows 7 64-Bit / Windows 8 64-Bit Video Card: NVIDIA GeForce GTS 450 / ATI Radeon HD 5870 or better Sound Card: Yes Free Disk Space: 40 GB

Once you installed the memory, did you enter into the System BIOS Setup screen? Do this and verify that the system recognizes the newly installed 2GB RAM. This should let the system access the new memory once you boot.

Please look into the below link for user guide manual to install Memory into your computer:

You should be able to do so.
However most manufacturers recommend installing pairs of matching RAM.
This is to take full advantage of the dual processor...

Hello,

Yes, you should have matching memory sticks to insure you have the same specs for each slot.

Good Luck

did you only install one 1 gig stick if so thats the problem ram has to be in matching pairs so for 1 gig you need two 512 sticks

Seems the memory is not comatable with the motherboard. Replace the old memory and visit http://www.crucial.com, they have a scanner tool which will confirm what mem can be installed.

if this is dual channel memory, you have to use matching pairs for each channel. 2 kingston sticks will not neceserrily be a matching pair.

maximum memory is1GB for your motherboard, you can only install 2 x 512MB, sorry.

This is likely a memory timing incompatibility. You can go into the BIOS settings of many motherboards and set the timing specifically for each RAM slot, but without knowing exactly which piece of RAM you have I can't tell you what to set it at. You could use the utility CPU Z, install one stick, run the utility and write down all the memory information, then install the other stick and write it down too. Then go into your BIOS and see if you can set all of your specifications to match the memory.

Of course if you could find someone to swap sticks with that would be easier. Some motherboards are more picky than others about which sticks they work well with, name brand manufacturers are more picky than aftermarket in general.
