your board support ddr2 only the ddr3 memory wont work see specs in your user manual
Guys, the very topic of this thread is asking if upgrading the motherboard to get DDR3 support is worth the money. OP knows that his/her board does not support DDR3 and is asking if upgrading the motherboard, making a memory upgrade possible, is worth the money.
IMHO, it is better to save the money to buy a new motherboard, cpu, ram(next gen) than just the minor upgrade. You can buy a SSD as boot drive to speed up the system, it will be the better investment imo or the Seagate Hybrid drive to have faster boot up and launch time for applications. Upgrading to DDR3 will not have significant performance increase. SSD and Hybrid drives do save you time.
