Ram question

post #1 of 13
Thread Starter 
Right now i have Two 2g DDR2 Ram sticks and a friend has a motherboard that's better then mine and i have two 1g DDR2 Ram sticks laying around his Mobo has 4 slots mine has 2. So i was just wondering would it hurt to mix the DDR2 2g with the DDR2 1g ram sticks.

Would they need to be the same speed or?

Right to clarify, You have 2x2gb sticks and 2x1gb sticks?

You can mix and match sticks of ddr2 but they will need to be the same speeds aka 800mhz,

The way you would do it is like this.

Slot one (far left) 2gbstick second slot next to the first one 1gb stick and then the 2gb stick and the 1gb on the far right

2/1/2/1 that should how it looks like

Some boards might be ok to have mix speeds, I remembered my mums board had 2sticks of 800mhz and 2 667mhz and it was ok about it but, I think you have to keep them in the same slot config as above

1. The configuration of the motherboard's memory channels can be different. Either read the motherboard's manual that should be online somewhere or often it is apparent the setup of the channels through the colors of the DIMM slots. The idea is to keep the 2 2GB sticks in the same channel and the 2 1GB sticks in the other.

2. The memory will be run at the same speed, regardless if they are the same speed. The higher speed sticks will be dropped to the lower stick's speeds. You can go to your BIOS and mess around with speeds, just keep in mind all sticks are run at the same voltage and same speeds so mix and matching can make things hard to find a good compromise of settings.

Nice

Tbh never really mix and match ram much prefer to have the same sticks just so I know that they will work with each other.

Each to their own I guess.

lol, i'm confused so is it okay to mix and match or is it a bad idea?

agree with what markisa said
you can mix ram's but the faster ones will be downclocked to lower ones

keep 2gb sticks in same channel and 2 1gb in other channel, you can refer to your motherboard guide to get where exactly should you place your ram sticks

Ok, but with the ram being downclocked won't it make my ram overall slower?

It won't hurt to try to mix and match memory sticks, its just that each memory stick uses a different chip and sometimes will not mix and match stabily. Even if its made by the same manufacturer like gskill they can use different chips for different versions of their model, even sometimes for the same model but different revisions of the model. The only real way to be safe today that memory will work with eachother is by purchasing the sticks in a kit together. Otherwise, nothing is guarenteed, but there still is no problem in trying. All you have to do is stick them in and see if the computer starts up. Sometimes with more memory you have to loosen the timmings or downclock them to work also, so if the sticks don't work together at stock settings don't be discouraged. If you do find settings that they start up with eachother then just download memtest http://hcidesign.com/memtest/ and run the test to 100% to check for stability and if it passes then they work perfectly fine

The ram being downclocked will make your ram overall slower, usually that is the side affect with more memory being mismatched, slower speed for more memory, even if you purchased 2 kits of the same memory it would work the same most of the time.

So would you recommend to do this or not to? Sorry i'm a complete newb when it comes to this stuff.

I understand what you guys mean but i don't know if losing speed for quantity is better or not.
