Your onboard ATA-133 is almost equal in speed to the SCSI adaptor...
It's not the protocol, it's the drive hardware itself that makes the speed, and IDE still delivers a good (if not better) performance for a lot less money.
And most important: you need a PCI-64 slot (twice as long, often other way around because of the voltage position gap) to get the maximum speed (320MBps) out of those cards, and as the normal consumer motherboards don't have those, you will only get problems with it not fitting (last half of the connector sticks out at the end) and less speed (160MBps, which is awfully close to the rated 133MBps of the onboard IDE)
The trick with the DDR modules is this one: if you have 2 modules of the same type (capacity, per-chip capacity, CAS latency) in the special marked slots, it will give 5-10% more performance in memory-intensive applications (Gaming etc.)
But if you are planning to upgrade the memory amount just stick to one, and buy an IDENTICAL one (capacity, CAS and per-chip capacity) when you upgrade
