I'm using a Gigabyte EP45-UD3R, E8400 Core 2 Duo, Windows 7 Ultimate 64bit, w/ 2GB of DDR2 800.
I want to upgrade my ram, but still use my old ram. I looked in my motherboards manual and it says "It is recommended that memory of the same capacity, brand, speed, and chips be used". Has anyone tried using this mobo and tried to mix match memory sizes and brands? I figured i would have to at least get the same speed. But can i attempt to put 2x2GB ddr2 800 of say corsair? and still have it work? the brand i'm using now is pqi. I know it says in the manual not to, but i just wanted to know if anyone has tried with this mobo and had it work. thanks for you time.
Most important is the voltage. If the voltage is the same, or very close, and the latencies are the same, or very close, it PROBABLY will work. But you can never be sure. Sometimes memory just does not like to be mixed with other memory, and some motherboards are more picky about it than others. You just never know.
However, do a double check on the voltage thing. If you have sticks that run at 1.8 volts, and you toss in a couple more that run at 2.3, you are going to have problems for positively certain.
awesome, thank you guys. my timings are 5-5-5-16, at 1.8v. running at 333MHz. so, in theory, if i bought ram, with these similar specs, it should work? no matter the brand? and what about the size? if i added 4GB to 2GB, equaling 6GB, would that work? and is memory compatibility better with win7? or does it just depend on the mobo? sorry if these questions are redundant. i know they've been asked before, but i just wanted to know about this specific mobo. i probably should just buy the ram sticks and be done with it. but anyways......thanks for you time and advice
my ram is underclocked to match the the bus speed, which is 333MHz. im positive the ram is 800(PC2-6400), i still have the order saved on newegg. the item is deactivated though. and they're different from the ones on their website. different heatsinks anyways. the timings are different too, but this could have to do with, my settings in bios. i'm not very keen when it comes to oc'ing and timings, so the settings are mostly set to auto in the bios. and it has fancy features like "turbo" and "fast" that i probably have set to as well. so i guess i'll try the ones off their website that must be the same as what i have, just different heatsinks. thanks for your help. i'll just cross my fingers and see what happens.
