which RAM from those two for my Clevo P170HM

So those are the two RAM options I can get quite cheap here in Austria:

G.Skill SO-DIMM Kit 8GB PC3-10667S CL9-9-9-24 (DDR3-1333) (F3-10666CL9D-8GBSQ)

and

Corsair ValueSelect SO-DIMM Kit 8GB PC3-10667S CL9 (DDR3-1333) (CMSO8GX3M2A1333C9)

The MALIBAL Satori P170HM comes with 2x 4GB 1333Mhz RAM so I still have two slots left. No idea what RAM it is :/
Which ones of the two above should I use? Or are they both crap?

Thanks

 

For the best, most stable and glitch free platform performance I would install 4x 4GB, Identical modules. Not a requirement - but (greatly) recommended. Either of those two listed will do (as long as you don't mix and match them...).

To see what you have now, download CPUz and check out the Memory and SPD tabs.

See:
CPUID - System & hardware benchmark, monitoring, reporting

 

Hmm actually never heard that before.. 4x4 same RAM modules to be recommended :S

I guess I will wait for the arrival of my laptop then and see what RAM it has inside. I bet some expensive one

@edit: according to MALIBAL its Samsung Original Memory.. so I guess it is this one:
https://www.amazon.de/DDR3-1333-PC3...FCK2/ref=sr_1_1?ie=UTF8&qid=1319229323&sr=8-1

It is fine as well?

Thanks

 

Actually, it's 4 identical SODIMMs that are recommended. You want at least matching SODIMMs paired for dual channel. For example, in my G73 i have 2x2GB in slots 2 & 4 and 2x4GB in slots 1 & 3. All 4 SODIMMs Kingston 9-9-9-24. The only variation is in capacity and PCB color.

If the original is samsung, then samsung. I would wait to receive the notebook before ordering though, sometimes you get different RAM. I got DDR3-1333MHz instead of 1066MHz in my G73 for example, supply shortage of the latter, worked out in my favor .

 

Nah, no such thing as expensive/'good' memory - 4x 4GB is less than $100 if you shop wisely. Unless you're overclocking your system (you'll need an extreme processor to do that, btw), any RAM is great ram (with lifetime warranty from a reputable dealer).

Yeah, that RAM is just as good as any other. Buy RAM on price, not brand name (or, 'specs').

Since you haven't received your system yet, why don't you order it with the smallest modules they have available (or simply the full 16GB's if their price is decent)?

@tijo, yeah, I meant SoDIMM modules too.

 

So far, i have heard of two cases of RAM not playing nice together and in both cases, it was corsair RAM (probably just happened that way) with a non corsair SODIMM/DIMM in the other paired slot. I haven't seen any case of paired identical modules causing problems. Still, there is no reason not to play it safe. I agree with tiller, if you can order it with a 4GB config, do so and buy 4x4GB.

@tiller, i know you meant SODIMM, i use SODIMM' stick and module interchangeably depending on how i feel .

 

Hmm I'm kinda confused now.. so you say the brand doesn't matter when mixing RAM as long as it is the same SODIMM ?
In my case, the G.Skill/Corsair/Samsung would all have the same SODIMM ?

Well I actually thought the 8GB of RAM are way enough (when ordering)... but since I now found those 2x4GB RAM quite cheap, I tought I would upgrade

 

No, Brand doesn't matter as long as all modules are identical. Different brands will not guarantee identical SoDIMM modules.

 

SODIMM refers to the type of RAM module (stick), SODIMM is laptop RAM and DIMM is desktop RAM, as simple as that.

What we are saying is that identical SODIMMs, brand, size and timing is the config that is the less likely to give you problems. Matching SODIMM timings and size is next to it, after that it is matching pairs and finally completely mismatched SODIMMs is more likely to cause trouble. Note that all those three configs can work very well in the best case. RAM problems are always weird, i have used mismatched sticks without problems, but others haven't been so lucky.

EDIT: The only config i actually try to avoid is completely mismatched SODIMMS. For the record, the weirdest thing i saw was 4 matching 4GB corsair DIMMs in a desktop that caused instabilities, tried 3 sets of 4x4GB too and all were unstable (my luck with corsair hasn't been good to say the least). I don't think i'll ever see that again. Anyways, don't worry about potential problems, they are rare, some of us have been messing with computers for some time so we had time to see a few strange cases.

 

Okay so the SO-DIMM would be the same for the samsung/corsair/g.skill ? How do I know about the timing? is it the 9-9-9-24 number? If yes, that would be the same for all three as well. And what is the timing even saying?

thanks alot !

 

Timing refer to the different latencies and yea it is those 9-9-9-24 numbers:

For example, the first number represents the number of clock cycles before a new instruction sent to the RAM can be executed. For more information, read this: Understanding RAM Timings | Hardware Secrets

Technically, all laptop RAM is SO-DIMM, however, we often use the term SO-DIMM to designate the physical RAM stick which might be different depending on the manufacturer. The connector type, size and pin arrangement will be the same for all DDR3 though and they will all work in any DDR3 compatible laptop. Not sure if that is clear, it sure wasn't clear when i first got into computers.

 

Well in the end all those 3 RAMS have the same connector type, size , pins and timing.. so they should work well and without any troubles?

 

Yes, all should work without a hitch, so get the one that is selling for the best price .

 

thanks for your help !

 

of those two, just get whatever is on sale...they are nearly identical. I bought the Gskills and they have worked flawlessly

 

How exactly does performance drop or change if you're running more sticks than there are channels? I was pricing some Sagers yesterday and seeing some 24GB configurations lol (3x8GB) in a dual-channel memory setup.

Just looking for benches/documentation on this.

 

No benches or documentation that I could link you to (off the top of my head). Just personal experience over the years.

With 'balanced' configurations it wasn't a matter of getting more performance - it was a matter of being stable and glitch-free (that is the performance I'm talking about) no matter how the system was pushed.

The Sager you mention with 24GB in a 3x8GB config would not even be on my radar for long term use/purchase consideration - either 32GB (4x8GB) or 16GB (4x4GB) are the only 'sane' choices for me.

When a program or the O/S hangs, BSOD's or otherwise makes a nuisance of itself, I want to be as sure as I can that the build/config is as stable as I know how to make over the years - and then I can concentrate on correcting the Software issues and not wondering if the Hardware setup is somehow affecting it too (as I've seen in the past).

 

Just saw that the original RAM in the lapto pis for sale on ebay... costs like 4€ more than the one I listed above.. so I bought them since they are now 100% identical.

 

Get the cheapest

 

What does the following information mean of a RAM?
PC3-10667S
CL9-9-9-24
DDR3-1333
F3-10666CL9D-8GBSQ

Does it mandatory for additional RAM to be matched all the above ratings of existing RAM?

 

speed (bandwidth)
timings
speed (frequency)
Item code

 

Does speed (frequency) "DDR3-1333" means 1333Mhz clock frequency?
So, Bandwidth "PC3-10667S" means?

Which ratings should exactly be matched to get optimum result?

 

The clock speed in MHz is directly related to the bandwidth. All DDR3-1333MHz is PC-10667. Bandwidth is the amount of data that can be transferred: 10667MB/s. You want to match both timings and clocks, the bandwidth will match since the clocks match too.

 

Thanks...
But how can I match timing "CL9-9-9-24"? Is it written on the packet?

 

It is written on the specs sheet so look for that when you shop.

 

I see a lot of systems configurable for 3 or 4 sodimms but it's only 2 or 3 channel memory. How would one notice this difference in day-to-day use, if at all?
