Completely confused about ram choice.

My Dell Inspiron 530s had four ram slots and with my ORY007 motherboard can take 4 gb of ram altogether (4 x 1 gb).

I used the speccy program and the Crucial Scanner and memory tool.

Crucial suggested the following:

2GB kit (1GBx2) DDR2 PC2-5300 Unbuffered NON-ECC 1.8V 128Meg x 64

or

2GB kit (1GBx2) DDR2 PC2-6400 Unbuffered NON-ECC 1.8V 128Meg x 64

I thought: simple enough.

But then, an E-Bay seller brought up single-sided ram vs double-sided ram, and updating the BIOS. He was trying to help and I am glad to have this information.

But now, I am a bit confused. Does anyone else have the same exact pc I have: the Dell Inspiron 530S with ORY007 motherboard?

I want to install all new ram: 4 x 1gb. Is it important to be double or single sided, and how important is updating the BIOS before installing ram?

Please help.

The DDR2 memory can only be inserted one way due to a step in the memory slots which has to coincide with the notch on the DIMM's. Note the location of the step and notch carefully, and then insert the DIMM carefully making sure the step and notch line up (and, of course, the ends of the DIMM must line up with the ends of the slot).
The memory shown as a result of memory compatibility search at Crucial is compatible with the Dell Inspiron 530s, regardless of whether the DIMM's are single or double sided.

The memory will (or should) work in the system. In the unlikely event the memory doesn't work, then the BIOS may have to be updated, which is a fairly easy process.

I have used Crucial before with success, but I had never heard of single vs double-sided ram. However, I have updated my BIOS successfully. Now, my only concern is if it is single-sided ram, should the memory chips face my left or right hand. It would be just like me to break them. Thanks.
