Currently I have 3GB DDR3 PC3-10600 (broken down into one 2GB and one 1GB) that came with my HP Pavilion p6350z. As I was reading about upgrading it I was wondering if its okay for them to have installed a 2GB stick next to a 1GB stick. I want to get 2GB more ram, but I want to utilize dual channel capabilities.
I'm unsure if it would be more beneficial to get one 2GB stick, two 1GB sticks and put them next to each other, or one 1GB and one 2GB stick so I can match up with the installed 1GB and 2GB sticks (2GB + 2GB and 1GB + 1GB). I'm not sure if I'm misunderstanding how to go about this or not. I read the FAQ and some other threads, so sorry if I'm being redundant!
Here is my PC specs:
Windows 7 Home Premium (64-bit)
Foxconn H-RS880-uATX Motherboard
Athlonll X4 630 (P) (2.8GHz / 4000 MHz HT3) AM3; 2 MB L2 cache (95W)
3 GB (1 x 2 GB, 1 x 1 GB) DDR3 PC3-10600
500 GB 7200 rpm SATA 3G (3.0 Gb/sec)
SAPPHIRE Radeon HD 5770 1GB 128-bit GDDR5
SoundBlaster X-Fi Xtreme
Memory slots: 4 DIMMS
Maximum memory: 16 GB (4 x 4 GB) (64-bit OS)
Okay, I figured it out with CPU-Z I think. "Channel #: Dual" should mean the currently installed 1GB + 2GB sticks I have are running in dual channel mode. I also says "DC Mode: Unganged," which seems to mean each CPU core uses a different stick.
So basically I think it's best for me to get two more 1GB sticks or two more 2GB sticks. This way I can preserve dual channel and unganged mode. Correct me if I'm wrong?
^ You do NOT want the mix-match Dual or Quad Channel RAM, and you ONLY want to purchase Dual Channel MATCHED sets. HP didn't give a crap about warning you! Further, you do NOT want to mix-match Speed, CAS, or Voltage.
Therefore, if you want your PC to run 'properly' then please list the RAM Part-Numbers; use CPUz:
More than likely, your 1GB is going bye-bye to trade-off for a match-set Dual Channel kit...
