I just added a GPU in this PC. To do that I had to change the Motherboard... Here's my browser.geekbench.com/v5/cpu/14720972 results... :)

Hi, I have an old acer 7720z ick70 from 2007 with 2gb ram. The original processor is an Intel T2310 and the motherboard reference is ICL50 LA-3551P. I've already replaced the hdd with an SSD, the processor I'd like to put a T7300. For the memory sticks, I'd like to put 2x2gb but it doesn't work, I get a blue screen on startup, either with windows 10 or 7. In the bios the 4gb are well recognized. These are old memory sticks from another PC with exactly the same references (so-dimm ddr2-5300s 667mhz). They work in another pc or one by one in the acer. Any ideas? Upgrade not possible? Thanks in advance
