Hello

I've built my Unraid Server few months ago, and it works fine

I'm using a ECS AMD690GM-M2 with 1 x 512Mb DDR2 800 (PC2 6400)

1) Do I need more RAM?

2) If yes, can I complete with 1 more module (I cannot find the same module anymore). For example 512Mb+1Gb or 512Mb+2Gb

Or should I buy 2 new modules (2 x 1Gb) to run dual channel?

 

Thanks

If it works fine, then no, you don't need more RAM.  If you want to add more anyway, then you should be able to mix and match RAM sticks, most motherboards allow that.

Since I already have 512Mb but I can't find the same one, I will have to put let's say 1Gb or 2Gb on the 2nd memory slot

1) Is 1.5Gb a good amount of RAM, or 2.5Gb is much better

2) Do I need to prefer dual channel (like 2 x 1Gb) but in that case I would not be able to re-use my 512Mb .......!!!

Do you run any unRAID add-ons?  If so, then more RAM will likely help them run better.  If not, then you don't really need any more RAM.

 

Dual channel doesn't really matter.  1.5 or 2.5 GB will work, unRAID doesn't really care either way.

No, I do not run any add-ons (as far as I know.......)

What are those add-ons for examples?

Any add-ons that are a "must have"?

Here is a list of unRAID add-ons.  The User Customizations forum contains all the active add-ons threads.  I consider unMenu to be the only 'must have'.
