Max Ram Speed for Sager 9872 laptop?

just purchased one, it comes with DDr2400, will it accept faster ram?

If so, is faster ram noticeable?


Laptop includes i7-6700 3.4ghz + Nvidia 1020

 

What model is that? P870DM2? If so, XMP 3000MHz is Clevo's listed maximum allowed RAM, but 2400MHz is the highest accepted non-XMP speed.

 

hello, yes Sager 9872S is also known as Clevo P870DM2.

i need to read up to understand XMp then. So 2400 is highest nonXMP okay sounds good. thank you.

 

XMP is nothing to understand. It's a "profile" on the memory (like changing from balanced to high performance in windows) except that you do it in the BIOS, and it needs to be supported by the installed sticks. So, if you want say, DDR4 3000MHz XMP enabled, you need to grab something like this: http://www.gskill.com/en/product/f4-3000c16d-32grs and enable XMP: 3000 16-18-18-43 in the BIOS.

 

oh ok.

so would a memory speed of ddr4-3000 w/latency 16
be faster than say ddr4-2400 with latency 14?

 

in theory, all current clevo bios versions for that model (including premaMOD) allow for a max. of 3200 Mhz. but currently, 3000 Mhz is the fastest available, with 3333 Mhz sticks already announced but not available yet

latency is basically a "waiting time". so rule of thumb: less waiting time is better / faster! at same clock speed, say 2400 mhz, a latency of 14 is faster than a latency of 16 because the sticks dont "wait" as long to process new data.

rule of thumb: clock speeds are more important than latencies! so 2666 mhz CL16 is faster than 2400 Mhz CL14! although this becomes relative when u compare large differences in latencies. thus, 2400 Mhz CL12 could actually be faster than 2666 Mhz CL20

 

Actually it should be a little different than that. Some programs LOVE the higher speed, but in most usage cases, speed + timings are the combination. Most of the "RAM speed makes no difference" posts would use similarly bad comparisons, like 1600MHz 9-9-9-24 versus 2133MHz 12-12-12-30 or something, and then claim "no aggregate change" or "maybe 1-2fps".

Also look for RAM that has different timings, like Kingston's 2800MHz is 15-15-15-36 for laptops, but G.Skill's 3000MHz is 16-18-18-43, making the Kingston the faster overall set.

Eh we're probably going way over OP's head though. But holy meowmix, does good RAM help. I upgraded my RAM recently courtesy of Luna being Luna, and holy... the difference is insane. I legit gained like 30fps in Evolve Stage 2, far less other games.

 

well i wasnt talking about where and when such ram upgrades DO make a difference, just where the higher bandwidth and overall performance lies

and ha, i actually noticed ur upgrade! was about time! im still trying to finetune my sticks to 2200 mhz, unfortunately 2400 is out of the question... in any case, faster ram really helps in minimum fps gaming! and overall system snappiness
