Windows 7: RAM performance

lffoar · 16 Jan 2010

Hi all,
I'm running 8Mb patriot DDR3 1600 RAM but read somewhere that my i7920 CPU only recognises 1333. If that is so, how can I get full value from my RAM? Txs Harry

These processors support DDR3 memory with a maximum frequency of 1066 MHz. If faster DDR3 memory is used (such as 1333 MHz or 1600 MHz), it will be down-clocked to operate at 1066 MHz.

You can overclock the RAM if your motherboard will let you.

Your FSB of your CPU will determine how much your RAM will perform I have a Q6600 quad and the FSB is only 1066 but I have DDR3 1333 but its stuck at 1066 unless you want to overclock with is not highly recommended=, the other thing you can do is try going into your bios and set the RAM to FSB ratio to suit your RAM speed.

.
As noted check your BIOS settings to see if you can change the RAM clock speed independently. Be aware if the computer doesn't like the new speed it may not boot. You will need to return the BIOS settings to default by setting a jumper or removing the battery on the motherboard (check the motherboard manual).

Considering my comp's performance is satisfactory as is, I think on what has been said here and other advice I've had, the best option is............
"if it aint broke don't fix it"
Thanks to all for your input
