Mixing two different sizes and voltages of memory on a board.

[Mister Lemons]

I've come to accept that my computer is neither the fastest or greatest around. I have grown tired of the performance and 'lag' it gives, struggling to do the most basic of tasks. Taking 10 seconds to load Google chrome when nothing else is running is unacceptable, nor is 95% RAM used when playing a game.

I know there are loads of threads and discussions out there about this topic, but my situation is a smidge unique giving that the RAM is of a different brand, timing, AND power, and my searches have turned up unsuccessful.

I know SOME RAM can be mixed and matched with the only downfall being that the MoBo will tune everything to the slowest stick. What I don't know is how safe it is to mix the sticks I have available to me under the following circumstances.

-One stick is 1.35v @ 4GB, the other is 1.5v @ 2GB
-If it is safe to do so, would enabling XMP harm anything in any way?
-This is a micro-ATX board with a mere 300 watts powering it

I proceeded to take some statistics with each setup and match them together knowing it was safe for a short period of time, if at all.

These are the results. (If one set looks better than the others, please do inform me)

So here are my questions.
1) Are there consequences to mixing two different brand sticks wit two different power requirements over an extended period of time (I.E. frying one or both of the sticks and/or motherboard)?

2) If not, would it be alright to enable XMP in the BIOS and set everything else to 'Auto'?


All input would be appreciated.

Your fine, nothings going to fry or blow up as far as the DRAM goes and what it's at, perfectly safe

You're positive? Despite differing speeds, brands, and POWER, they are compatible and there is no harm to be done?

Yes, it's not a good idea to mix DRAM, primarily because it can be problematic, but if you do mix and get them running, as long as you don't go way out of spec it's perfectly fine, and you are far, far from going way out of spec to a point that would bother me. DRAMs been a specialty of mine for quite a few years, really started studying it heavily back around 2007, worked with a few teams that went after record scores in the 3DMark BMs, and have done forum support for GSkill for about 5-6 years now, am an Admin on their forums

That's what I was looking for. Thank you for your time and knowledge input.
