Mixing ram sticks issue?

I've got 2 new sticks of ram from a friend for free. These are the two sticks Newegg.com - A-DATA Gaming Series 2GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model AX3U1600GB2G9-CG The sticks i currently have are this Newegg.com - A-DATA XPG Gaming Series v2.0 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model AX3U1600GB2G9-DG2 I know you shouldn't mix ram but the sticks are almost identical will there be issues if I run two of reach in one machine? Thanks in advance!

I have run mixed ram before with no problems, it's not the best thing to do but the only way to find out is to do it and see..If the computer becomes unstable then you'll know. I noticed the latency and voltage are different I would be cautious I have never done that I have done different gigs though only of the same exact specifications...

If the new stick is listed in the qualified vendors list. Should be ok.

It's not a good idea to mix RAM.

I do agree with seth in that the specs should be the same. Make sure you're not pushing 1.8volt in the RAM as one set is listed as 1.65-1.85volts while the other set is listed as 1.55-1.75volts. You'll have to find a happy medium.

On the flip side you'll now have to make sure the RAM is getting at least 1.65 volts now as setting to 1.55volts will starve the set requiring 1.65volts.

Basically you'll now have to "manually" set your RAM's voltage setting!

Good luck.

plug them in and see, we can't tell you if it will work or not since it is very unlikely that someone has the exact same setup of you on this forum.

Since you are running x64, you may get a small advantage from the extra ram.
When mixing ram like you have, it defaults to the slowest speed.

I am confused. what speed is it going to run at if both sets are 1600?

It'll run @ 1600MHz since both sets are 1600.

The only issue is making sure the voltage of the RAM is set manually as most motherboards will set a voltage of 1.5, not 1.6 which the other set requires.

Mismatched Ram Slow, will matched sticks fix issue?
When I ordered my laptop from HP it came with 6 GB of memory. I realize now that they are mismatched sticks and the memory is only running at 533 MHz (7-7-7). The laptop has an i5 560M and the memory should/can run as fast as 667 MHz. If I buy a pair of matched sticks will they run at PC-10600 (667...

Mixing RAM
I have 4GB of DDR3 Ram right now, and I'm thinking of adding another 4GB. I have this ram right now, but it is deactivated on the Newegg site. Because I can't buy that ram anymore, can I mix it with this? Because, as far as I can tell, they are basically identical. Thanks :D

Mixing different ram
I just installed 64-bit and I'm looking to get some more ram. I currently have 4GB of DDR2 800 OCZ platinum XTC (2x2GB) with timings of 4-5-4-15. The problem is I can't find this ram anymore. Would it be okay if I got more ram with different timings and mixed the ram I have with the new stuff?

RAM... Two sticks, three sticks, dual channel, triple channels, huh?
I ordered some computer stuff at 4a.m. and I had a major brainfart when doing so. I ordered some Crucial ram that came in 2GB sticks, Newegg.com sold is in doubles and triple packs, my thought was well, 6GB is better then 4GB when ordering but after doing so I thought, wait, don't you normally...

Question about mixing RAM
So I was just curious how much of a loss of performance or how much instability would increase if I mixed two different brands (two different Cas Latencies) in my build? Right now I have this one: Newegg.com - G.SKILL 2GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Desktop Memory Model...

Mixing RAM
I've been thinking about buying some more ram, because I have read here that some believe that more than 2-4GBs is needed to get proper performance out of W7 x64, but I do not want to waste what I already have. To be able to increase the RAM on both of my rigs, I would need to buy 2 sticks of 2GB,...
