[QUOTE=Albert;2784028]The various Dell documents for the laptop say it is merely DDR3, and a separate Dell article notes that DDR3L (low voltage) memory was only supported for 4th gen & newer Core i5/Core i7 (and related) mobile processors.
As your system uses a 1st gen Core i5, getting a ‘plain’ DDR3 SODIMM will work, but going for a DDR3/DDR3L SODIMM will be fine, too. (DDR3L modules are inherently backward compatible, supporting 1.5V and the lower 1.35V. Plain DDR3 SODIMMs support only 1.5V.)[/QUOTE]
So basically, I can get any DDR3 SODIMMS at 1066Mhz, as long as it supports 1.5V. Is that what you’re saying? Also, it sounds like [B]all[/B] DDR3 cards are backward-compatible with 1.5V slots. Yes? No?
Dell’s documents confirm that the system bus (and memory speed) are operating at 1066 Mhz. That’s your target for you search, and should be your only concern (as long as you make sure you’re getting an SODIMM rather than a desktop-type DIMM).
I know what the documentation says. In fact, I even mentioned that in my original post. However, I had some confusion about conflicting reports from two different programs (neither of which said quite the same thing as the documentation), which Dee rather nicely cleared up.
[QUOTE=Dee;2784030]Also 8GB is the maximum RAM supported, across 2X 4GB SODIMM.
You can probably buy faster memory than 1066MHz, but it will still run at 1066MHz.[/QUOTE]
In other words, each card can have <= 4GB, and must be able to run at >= 1066 MHz, right? Before you answer, I’d like to mention that I’m not really interested in having the fastest RAM in the world. I just want to make sure the RAM I get works on my system.
