Memory upgrade for 0RY007 motherboard

Jump to solution

I have been doing some research on memory for my Dell Inpiron 530.  I have 4 slots for memory(2x1GB @333MHz, 1x512MB @333MHz and 1x1GB @400MHz installed now)  I am planning on adding 4x2GB @800MHz but have to do it in 2 steps(2x2GB now and 2x2GB later).

From what I understand, the 800MHz will only run as fast as the next highest speed.  Is this correct?  Also, If I decide take out the old RAM and only run the first step in my upgrade(until I'm able to get the other), is there a specific slot that NEEDS to be filled on the board?

Any help would be great!

Hi Mcoomer146,

I suggest you go to the Crucial site and use their upgrade adviser to check.

Osprey, thank you for the reply.

I couldn't understand the Crucial adviser.  Only thing it told me is the stuff I already knew(how much RAM, frequency, and speed).

But, here is what I learned.  I took out the 1x512MB @333MHz(DDR2 PC2-5300) and one of the 1x1GB @333MHz(DDR2 PC2-5300) and added 2x2GB @800MHz(DDR2 PC2-6400). 

Started my PC checked it with CPU-Z, it showed 6GB RAM and everything was running @333MHz.  So I took out the other 1x1GB @333MHz(DDR2 PC2-5300), restarted showed 5GB RAM and everything was running at @400MHz, which is the same as the stick I didn't take out.

So, doing this I I have figured out my question.  To use the full capacity and speed of my memory, I should have 4x*GB @800MHz(DDR2 PC2-6400).

Oh, and there doesn't appear to be a "required" DIMM slot on the 0RY007 motherboard.  Seems like it checks to see if the slot is filled, if not, it moves to the next slot.

Again, thank you for your help!
