Hello Guys,

I just curious about upgrading my ram laptop, I heard that corsair vengeance for laptop has better quality compare to other product, could anyone clarify my doubt? I also wondering that what's the meaning of ratio SPD latency of ram for? for example, 9-9-9-24. If I want to upgrade, what is the essential things should I looked for? such voltage, latency, speed, etc.

Thank You
Hope to get explanation and review about my doubt

Pretty much any ram available on the market is good if you're looking at laptop ram modules. The names that stand out are, G.Skill, Corsair, Transcend, Mushkin, Kingston and a newcomer Klevv. You won't be disappointed with either brand though there are a couple of differences in their appearance and target market appeal. Kingston's HyperX's, Corsair's Vengeance's as well as G.Skill's Black PCB'd kits are meant for gamers or people who need higher spec'd dimms.

Speaking of spec's the ratio is actually referred to as timing/latency of a ram stick/module/kit. 9-9-9-24 is a stick/kit with latency or CL of 9 and is arranged in this manner :CL-tRCD-tRP-tRAS-CMD whereby the last 2 digit numbers are the tRAS. You can read through this article to learn more.

The essential things you should look for while purchasing ram is to see if the kit is compatible with your unit/system. Compatibility can be judged by looking at the platform you're trying to upgrade to, the voltages it needs, as well as whether the motherboard inside your laptop or your desktop can accept such a kit and can perform at their rated speeds or if an overclock will be necessary. Often times older systems had a problem dealing with dimms that were populated with single side sticks and the same happened for dual sided sticks. Lastly you should also see the price of the kit as often times the price of an older kit is the same as a brand new kit with better timings and perhaps design and thermal output.

As platforms progressed forward we are seeing less power requirements for the memory sticks as they once used 2V of power and now they use about 1.35v.

Though we've been side tracked by your thread title and thread body. If you're looking for a ram kit for your notebook then take a look at 1600MHz kits with 9 or lower timings and the voltage requirements will be outlined on the ram slots at the bottom of your laptop. Since it's 4th gen mobile Intel processors I'd say 1.5v would be a good start but if you can find a donor who can lend you 1.35v rams then you can test them out and see if they run well. lower voltages mean less heat output and less stress on the memory controller within the CPU.
