MacBook 5,1: RAM upgrade to 6GB

I currently use KINGSTON KTA-MB1066K2/4G 4GB KIT with no problem.
After a chat with macsales they insist and agree that after their tests macbooks 5,1 can have RAm up to 6GB.
I was wondering If anyone knows what will happen If I use one 2GB from KINGSTON KTA-MB1066/2G 2GB MODULE.

Thanks very much for your time.

MacBook 13.3'' Unibody (5.1), Mac OS X (10.6.4), 4GB RAM (KINGSTON KTA-MB1066K2/4G 4GB KIT), 500GB Seagate 7200 HD

Your Mac only has two RAM slots. That means you'll have to find a 4 GB module to go along with your 2 GB module to upgrade to 6 GB. The Kingston 4 GB Kit as I Google it shows it is i two individual 2 GB modules.

Actually according to OWC the 5,1 can use 8gb of RAM

This was only recent, during the time of this thread's activity, OWC would not recommend or sell anything larger than the 6gig kit. It wasn't until real recent they acknowledged and began offering 8gb kits.

I used this as a guideline for upgrading my Macbook Alum to 8GB and things seem to be running smoothly for the past day or so.

I'll report back if there are any issues.

8 GB works fine, my MacBook Unibody 5,1 has 8 GB Corsair memory installed (2 x 4 GB) and works fine, and has been for a week. Tested under full load/all memory used, no issues.
