You indeed have the first generation Mac Pro. It can use up to 8 - 240-pin PC2-5300 (667MHz) DDR2 ECC fully-buffered DIMM (FB-DIMM) in (matched pairs.) The modules should have an Apple certified or similar heat sink. Do not use DIMMs without heat sinks as they will not last and may be subject to frequent errors. The DIMMs must be fully buffered (FB) and must be error correcting (ECC) and installed in matching pairs.
Whatever your local dealer sold you if there's no heat sink, they aren't FB and ECC modules, then don't use them.
For proper installation see the following:

Mac Pro Memory Configuration
Memory Tests- "2008" Mac Pro
Ram should be installed minimally in matched pairs and optimally in matched quads. This means the memory modules are the same size and specifications. They should also be equipped with the Apple-certified style of heat sink.
That dealer doesn't know squat it sounds like. Not when it comes to the Mac Pro.
The heat sinks haven't changed. The price is better than it was 4 yrs ago.
Hynnix is fine.
