Any disadvantage with a single memory card

  olyman 10:17 28 Sep 2018

Memory always seems to be paired. My PC came with a single 8Gb card. Is there any performance disadvantage. I'm thinking of an upgrade to improve video processing. Would a matched memory card be an advantage? I was thinking of adding a budget graphics card to replace the integrated graphics. What's better doubling up the memory or improving the GPU? I suspect doing both will be the answer. It's a newish PC with an i5 7400 Kirby Lake processor.

Your motherboard will almost certainly have dual-channel memory support, increasing effective bandwidth and speed, it will need 2 or 4 memory modules for this to work. As you are doing video processing, more RAM and dual channel enabled, should be beneficial.

Further to the above, if you have limited budget prioritise RAM over GPU and, in any case, unless you are gaming as well don't bother with an expensive high-end GPU.

Thanks for your prompt response which confirms what I was thinking. I can easily double up to 16 Gb as there is a spare slot. I was thinking possibly of a low end graphics card to free up memory used by the integrated graphics. I would be limited by the PSU in any case. I'm not into gaming other than some ancient flight simulators but my camera is 4k capable so I was thinking of future use.

your cpu already has 4k support click here double up the RAM and see how it goes.

An exactly matched Memory Stick would be the cheapest and most effective upgrade.

Upgrading Graphics Cards is an expensive game

Thanks for the comments. I'm going to double up the memory. The limit on adding a graphics card, apart from cost, isn't the CPU but the power supply.
