2x2gb or 4x1gb?

post #1 of 6
Thread Starter 
Hi all,
I have a question regarding ddr2-800 ram for a Asus P5K Deluxe mobo and Intel Q6600.

I have the choice of getting one of two types of ram:
1. G.Skill 4x1gb ddr2-800 CL4-4-3-5; or
2. G.Skill 2x2gb ddr2-800 CL5-5-5-15.

I have asked this question in a couple of places, and was told to steer away from the 4x1gb solution, given the reason that using all 4 RAM slots on a mobo takes a performance hit.

Can anyone confirm this?

I guess my main question is, which of the two choices is better?

Hi there. I am still new to overclocking and the forum. But my opinion is that you go with option 2. Reason for this is you can alwys later on upgrade with more 2x2gig's for ddr2 800.

You may find that with 4x1GB your memory controller might be under a little bit of stress which would limit overclockability by a bit, but not much, I'd imagine. I'd go with 2x2GB myself

I don't think there is a real world performance between the two. If anything, go with the 2x(2gb) kits. Not only do you free up two slots for later usage, but RAM generates heat, and if you run four 1gb sticks to fill up your RAM slots, that whole area will be generating heat whereas if you have two 2gb sticks in dual channel, there is at least a narrow space inbetween them to have some airflow.

I say go for whatever is cheaper.

I have 4x1Gb and I can OC like a champ. Yeah, theres a good amount of heat, and I upped my MCH voltage, but I hear that people with 2x2gb that overclock do the same thing.

More than likely, by the time you need more than 4Gb DDR2 is going to be behind the curve. I doubt that you will really need to upgrade to 8Gb without going to DDR3 first. But hey, maybe youll keep this machine for years, I dont know.

IMHO, just do whats cheapest, I havnt seen ANY data (only opinion) regarding extra stress on the controller, or any legitimate performance difference.

Ideally you want to get 2 x 2GB

For the pure reason we don't get 512MB x 4 nowadays.

With 2 sticks you have a better chance of getting a higher OC. This is because there will be only ONE stick limiting the other from going further.

However if you have 4 sticks, you have more chance of the limiting stick being worse. Because you have a better chance of getting 2 good sticks compared to 4 good sticks.

This is the same with memory timings. You will possibly achieve better latency with 2 sticks compared to 4 sticks.

Also i read somewhere that 4 sticks will put more stress on the memory controller and the dimms themselves which will make it harder to acheive a good OC. I am not sure how true this is but for me, all signs point towards the 2 x 2GB

However the performance gain will not be that much so go for which eevr is cheaper. A lot of people on these forums run 4 x 1GB and have had no problem with OC'ing.

Also make sure you are running a 64Bit operating syste. A 32bit OS will not be able to run all of the 4GB it will only register 3 - 3.5 at the most
