I have a Gigabyte motherboard GA-G41MT-D3 [socket 775] which takes single channel DDR3 ram-there are only 2 slots.The board works fine & the ram read as 4GB-until I installed Windows 6-now it reads as 2GB & is as slow as ''Old Harry''.Kingston no longer make compatible ram in the larger GB sizes for this board.Does anyone know a suitable replacement,manufacturer,supplier or 2nd hand dealer -I would really like better performance short of reloading Windows 7.Can Anyone Help?
