mixing Kingston 1333mhz with corsaire xms3 1600mhz

[prashant10289]

Hey guys i have a Gigabyte GA G41 M combo motherboard
and i wanted to move from 1gb ddr2 to 2*4gb ram

from some place i am getting these two RAM real cheap
Corsaire 4GB XMS3 CMX4GX3M1A1600C9
Kingston 4GB Ram KVR1333D3N9/4G

I was wondering that is it ok to mix(1333mhz and 1600mhz, i am not talking abt mixing ddr2 and ddr3) them up and whether my mobo will support them since it says it is 1333mhz(o.c)

Thanks in advance

Mixing ram is always a gamble. Remember to remove the old memory as well. it takes DDR2 OR 3 not and.

You should be able to run it all at a lower speed, but just remember that while you have a good chance of it working, it is still generally not recommended.

Please also note that both sticks are rated at a different voltage.

It is best to meet the voltage and speeds of the slower stick. so 1333 @ 1.5 volts. Even lower speeds should not be an issue.

you will likely have to run them at 1066mhz but that shouldn't be a big deal. As Nuke mentioned you can't just add the new sticks to the old as you can't mix ddr2 and ddr3.

so different voltage is a prblm or not??

not really it means the chips in the higher voltage kit suck, but especially since I suspect you'll be down clocking to 1066 it won't matter they'll both run at the same voltage.

Thank you man....both of you

I would not go as far as to say that the higher voltage chips actually suck. for a while all 1600mhz memory was 1.65 because it was overclocked 1333. Newer memory got "better" because Intel did not want higher voltage. I have seen 1.8-2.0 volt ddr3 in the past even.

In fact the XMS3 tends to run under 1.65 volts anyway if you try. Also at 1333 it is rated at 1.5 volts.

I am running similar sticks at 1.35 volts @ 1333 8-9-8-20 1T

Closest sticks I have. Just gives you an idea of the other rated speeds and timings on those stocks.

Don't have the CPU-Z shots on this computer but the ram in my sig will run 1600 with 8-9-9-24 timings @ 1.42v and the rated 9-9-9-24 timings @ 1.35v and I even have 2 sets of them in my computer. The lower the voltage the better then chips in general There is only one reason to rate the volts that high, its because several of them are unstable at "normal" voltage.

1.35 is higher binned sticks. not all memory runs the same. just like you can get 2 video cards with a different boost frequency(the nvidia set one, not the card makers average.).

Either way, I was just saying some of the 1.65 sticks are not actually "bad" I do not run 1600 in that system because it requires a cpu bus speed change that I do not want to do.
