I have an older E725-4520 laptop.
It came with T4400 cpu and 3GB ddr3 mewmory ND WINOWS7 64 BIT.
I upgrade to windows 10 and 4GB ddr3 2x2GB ddr3, all is good.
I then installed 8GB 2x4GB ddr3 memory, identical modules.
BIOS and win 10 reported 8GB.
windows 10 very slow, somteimes sy interrupts at 90%
Removed 1 4GB module, win 10 ran great
Any ideas?
