I'll try and make this brief, but I need to be thorough to avoid ambiguities. I've got 8GB of RAM, in four 2GB modules. I want more RAM, so I'm buying a 16GB pack which comes in two 8GB modules. My plan was to leave two of the old sticks in, totaling 20GB (since I can't currently afford the cost to go up to 32GB).
16GB is obviously better than 8GB, but still isn't quite enough... so if it really comes down to it, I can just go with 16GB for now. However, I've read the following about mixing/matching: "You may be able to [mix and match], but if the new ram is not the same speed than it will run at the slower ram speed unless you manually change this." So, how would I go about manually changing this? In other words, it looks like I'll potentially be running into the issue that the new RAM will essentially be bottlenecked, but based on what I read, I can manually fix this. Am I correct?
How about the fan/heatsink on the old RAM? Would this be compatible with the new one or would it be safe to leave it off?
Other than the potential for "bottlenecking" the new RAM and my question about the fan/heatsink, are there any other issues I would need to worry about if I mix/match these?
1) Depending on your motherboard, you may have different options to change the speed and settings of the RAM. Which mobo is it?
2) I don't think its compatible, and I believe the fan is more of a gimmick than real performance.
3) Some issues might be that you must run the new RAM at the speed of the old RAM. For the sake of 4 extra gigs of RAM, this is not worth it. Unless you are extremely RAM strapped in your applications.
I would just use the 2 sticks, chances are much better that things will be smooth.
I put a link to the motherboard in the original post near the end.
I guess I'll just grab another two (identical) sticks in a couple months when I can afford to get the full 32GB. That'll eliminate any compatibility issues if they're identical to the ones I am buying now.
I didn't think the fan was too big of a deal, but I figured if I can use it, why not?
