I have just upgraded my laptop from win 7 32 bit to win 7 64 bit and everything went well but when i try to upgrade my ram from 4 gig to 8 gig it stalls at the windows start screen. could this be a ram speed problem ? I have flashed the bios to a newer version but this didnt help
turns out there is no bios fix for this problem. my laptop will only run ram with a 1.35vt and not the new 1.5vt, thats why it hangs
Depending on the model of Toshiba, there are 4 possibilities. a) The voltage of the RAM is too high. In this case, either just upgrade the RAM to 6gb. Or change both RAM chips to low voltage. b) It simply may not support the amount of RAM. This is more of a design flaw than anything else. I’ve had a few i7s that had this issue. It locked at 6gb RAM max. c) You may need to take out the RAM first, update to the latest BIOS, then install the new RAM. BIOS updates sometimes increases compatibility. d) You may have bad or incompatible RAM. I’ve seen a lot of problems with mismatched sets, wrong speeds, mismatched speeds, etc. The best is to have a matching set of low voltage RAM. Check your CPU and BUS speed to see if you need for example DDR3 1333mhz or DDR3 1600mhz. Store bought RAM has lifetime warranty, so if you find out RAM is bad, you can just RMA for replacement RAM.
