Mixing two 512 MB ram sticks with two 1G sticks of ram?

[connect4]

I have a GA-P35-DS3L motherboard:

And I currently have two 1 Gigabyte sticks of Kingston Ram (KVR800D2N5/1G)
http://www.newegg.com/Product/Product.aspx?Item=N82E16820134114&Tpk=KVR800D2N5%2f1G

Can I add two 512 MB sticks of the same ram?

Are they compatible and safe to put into my motherboard?

1. Same speed.
2. Same voltages
3. Same timings/latencies

So long as they are of the same voltage-rating and CAS Timings/Latencies, same speed in MHz and the right interface then yes, you can work them together in concert.

Kingston 1 GB
Speed DDR2 800 (PC2 6400)
Cas Latency 5
Voltage 1.8V
Heat Spreader No

Kingston 512MB
Speed DDR2 800 (PC2 6400)
Cas Latency 5
Voltage 1.8V
Heat Spreader No


Okay same speed, check. Same voltages, check. Same latency, check. Can't find latency any but it seems that:

timing = latency correct?

So these two RAMS should be compatible and my motherboard is safe?

Yes, is compatible and safe. Have fun
