Pondering an additional 4gb of ram.

post #1 of 8
Thread Starter 
Right now I have 8gb in my sig rig (2x4gb). I want to add another identical stick for 12gb but I have some questions.

1. Right now 2 out of 4 dimms are in use. I have the existing 2 sticks in the matched slots (both blue). If I add another stick I will have to put it in a white slot, using 2 blue and 1 white total. Will I lose dual channel mode? If so, will using all the slots (2 blue and 2 white) with identical sticks get dual channel back?

2. I heard using more than 2 ram slots can affect your OC....this doesn't seem likely unless I OC with the fsb, right? I only use the multiplier so will this still affect me?

And lastly of course, is it "worth" it for someone who does a lot of gaming, some video editing, and some virtualization?

It won't run in dual channel with three modules. Using four will net dual channel. I have four and it's running in dual channel. It simply needs pairs. There can be multiple pairs.

I'm not sure about the other one. With a traditional Northbridge, yes, that's true, as you need more voltage for more modules/addressing space, but I don't know about with the newer CPUs where the MCH is in the CPU, and in cases where you're overclocking with multipliers.

If you wanted 12GB, you'd have to buy a 2x2GB kit it would only affect your OC if you have the C2 revision. If you have C3 you're good.

You will lose dual channel mode when using more than 8GB and it will run in single channel/interleaved, halving your bandwidth and potentially affecting performance. Many apps will appear in dual channel including MaxxMem until you use more than the 8GB and everything reverts to single channel.

What is your peak memory usage now?


Video editing benefits from more memory.

VMs benefit if you have multiple ones running.

For video editing you will definitely see an improvement with the extra memory.

As for the VMs, if you are running 2+ then go for the increase in memory but keep it dual channeled with another pair of sticks.

I say, honestly, 8GB is pretty much enough
I video edit with 1080p video often in multiple layers and never pass 8GB, it's perfect
