DDR2 RAM Compability

Hi guys, lately I have been taking apart some old computers and now I want to upgrade one so if I sell it it will be even more attractive :). I'm not sure what motherboard I have but I don't think that this is essential for this question. I want to mix 2*1 gb ram with 2, 1 gb of ram (so extra sticks, one of two and another one of 1). The 2*1 is currently in my computer and it works fine. The 2 and 1 gb stick of ram was in my old computer which also worked (psu broke).

Specs: 2*1 gb ram HYS64T128020U-3S-A 1GB 2Rx8 PC2-5300U-555-12-EO
Specs: 2, 1 gb of ram MT16HTF25664AY-667E1 200753 BZAE02D008, 1GB (same for the 2gb stick apart from the product number i believe before this) 1RX8 PC2-5300U-555-12-ZZ 1GB, DDR2, 667, CL5

When it comes to these detailed tech questions I am a total noob! Any help would be appreciated!

  1. Mixing RAM isn't recommended at all.

    All sorts of issues can arise from it.

    It's best to have RAM that come in kits.
  2. I allready own the ram so I am not repurchasing it :)
