1 rank, 2 ranks ?! What it means ?

post #1 of 5
Thread Starter 
I have 2x4GB Geil Black Dragon, CL-9-10-9-28 with 1866Mhz

Now i bough another pair of 2x4gb, of the same ram, geil black dragon 1866Mhz CL9

And aida64 says to me that they are a little different, in terms of 1 rank and 2 ranks.

2 chips are 2 ranks, the ones i bought today, and 2 chips are 1 rank.

This is gonna be a problem ? I've enabled XMP mode, and they work on 1866Mhz with CL9.
here are the pics

Basically 2 chips are 2 ranks 8 banks, and the other 2 are 1 rank 8 banks.

Normally, single-sided and dual-sided memory doesn't work too well together but if you're not having any stability issues then there is nothing to worry about.

Then how do i needed to order the ram, the box is exactly the same. Doesn't specify there 1 rank and 2 ranks.

Anyone could tell me something about those two ? Or how to test for stability issues ?

I don't think there is any way to tell if modules are single or dual sided with Geil.

How to test stability? Try Prime 95 blend mode or multiple ~1500MB instances of HCI Memtest.

So the 1 rank memory is weaker than the 2 rank memory ?
