Depending on your mtrbd. it will be compatible. I mention mtrbd. as only in rare cases it causes a problem. You can visit memory online retailers for yet another source of ram of the original type, but the DDR2-677 will work as 533 as the best it can do. You can try Craigslist and eBay as well for vendors if you like, but checking: has provided good advice and being a retailer good ram to choose from.
