Gigabyte GA-MA790X-UD4P

I am using 4gbs 2x2gbs GSKILL DDR2 1066 RAM on a Gigabyte GA-MA790X-UD4P motherboard. I accidentaly ordered Corsair Dominator 2gb 2x1gb DDR2 1066.

Now my question is can I install the two 1 gig sticks from Corsair in the last two slots next to the two 2 gig sticks of GSKILL ram? So I would be totaling 6 gigs of ram or should I just go ahead and RMA the corasir and get another 4 gigs of GSKILL.

    The faster ram will reduce in speed to the slower ram (the timings). You'll probably be fine , having the same brand of memory is one of those enthusiasts obsession that is 90% cosmetic and 10% fact. Go for it.
  2. You can, but mixing memory can cause issues and is best avoided. You will have to play with the voltage and timings a bit to get a stable setting along with a few hours of memtest, run it if it posts, to make sure it's stable.
  3. The timing on GSKILL is 5-5-5-15 and Voltage is 2.00-2.10 and it is clocked at 800mhz because it just wont go to 1066. And the Corsair timings are 5-5-5-15 and Voltage is 2.20V. If it is going to be a pain I will just keep the product unopened and RMA.
  4. You said both were 1066 but if you can go ahead and return it.

    Yes both are rated at 1066, but this GSKILL ram has a lot of issues running at 1066. So just plug and play its clocked at 800mhz which is fine by me, Im just wondering IF I can safely run both. But I guess I will have to RMA.
