Can i use 1333 ram in 1066 laptop




















You can, both sticks will run at MHz. As long as your motherboard supports more than 8gb of RAM, which most of them do. Technically yes. Your motherboard will automatically down clock the RAM to to match the other stick. The reason is because the two modules are tested and compatibility is verified.

I wasn't trying to imply it wouldn't work with any Mac. I don't think anyone would read it that way, and if they did, bumpkiss to them. And you blithely ignored the part where I said things that aren't a Mac and wasn't directly commenting on what you said?

This is bordering on the edge of vegetative state stupidity. I also did not mean that all macs cant run with this ram, I meant that some macs will not run without modifications, because of firmware apple adds to prevent modifications to the machine.

Macs do run on the same X86 architechture as other PCs. The only difference is they try to lockdown what can be modified through adding firmware. Apple computers also contains very few parts made by apple if any at all, most is licensed from other companies intel, ati, nvidia, asus, etc. Just look what they did to their harddrives Good to see your "points" have come down to personal attacks.

At least I am weaving fact and logic into my assertions that you are an ignoramus. Search In. Share More sharing options Followers 0.

Connect and share knowledge within a single location that is structured and easy to search. I have 2 slots. MHz, because the motherboard supports this maximum frequency, and in single channel mode. Will they work fine with both running at MHz?

And will it be activated in dual channel mode in this case? And also they show me that it runs in single channel mode. Tried to see the tech specs on an almost similar laptop, with 2 modules identical to this one, they run both at MHz even if they are MHz both , and the Dual Channel mode is activated Dual Channel Ungaged, supose it's ok. Both memory modules should work and operate at MHz. If properly supported, the modules will operate in dual-channel mode, but both modules will be limited to the slower one, which is unlikely to be noticeable.

The RAM stick should simply run at the lower clock frequency. That number is usually indicated on a sticker on the RAM stick itsel or the case.

Divide the number by 8 to get the speed in Mhz. May be the newest Mhz don't support running at lower clock speeds so they are less likely to work.

The Mhz RAM can be identified by the number. So the answer is that Mhz memory modules may not work in a slot that supports only upto Mhz.
