Compatible RAM with Asus Motherboard?

Just got some memory from a friend and I wondered if it was compatible with my motherboard.  Obviously they are different frequencies so I wouldn't use them both if they were both ok, but which one is better and can I use it for my motherboard?

Reneon CL 2.5
256mb DDR 333 Pc 2700U


Kingston Infineon KVR 2.5 V

Let me know if you need more information.  What I gave is off the two cards.

Crucial and Kingston have memory configurators that tell you what RAM will work with your motherboard.  PC2700 DDR333 looks compatible, but only with a cpu that runs at 166FSB or less (in other words, most hyperthreading P4's are not compatible).

The Kingston Infineon doesn't have enough information, like PCxxxx rating.

Intel Pentium 4 3.0E Prescott 800MHz FSB 1MB L2 Cache Socket 478 Processor - Retail

Nope - the RAM that I could identify is too slow for 800FSB.  I don't know about the other one.
