Having had a look at the specs for both (click here & click here), I cannot find a reason why they shouldn't be compatible (but I have to stop short of saying they will work 100%).
Info from the Asus link about compatible memory:
- 4 x 184-pin DIMM Sockets support max. 4GB DDR400/DDR333/DDR266 ECC/non-ECC un-buffered DDR SDRAM memory
- Dual Channel Memory Architecture
