Best notebook RAM for an Asus G1S?

I have an Asus G1S-A1 and would like to go up to 3 GB of RAM as opposed to two; what is the best bang for the buck I can get for it that is compatible? Thanks a lot.

 

Your laptop utilizes pc5300 ddr2 sodimm memory.
If you have two gb of memory, you most likely have 2 1gb memory cards.
You will only have to remove one of the 1gb cards to get 3gb of memory. Simply replace one of the 1gb cards with a 2gb memory card.

I recommend this memory card, and its pretty cheap:

You can buy any memory card you want, just as long as it comes with a lifetime warranty.

Mixing brands should have no effect, correct?

 

Correct! This is not your fathers notebook (or RAM for that matter).

 

Mixing brands is okay, memory is prettu much all the same anyways.
Most of the memory cards use samsung, qimonda, micron or hynix memory chips.
However, I recommend getting from crucial, corsair, kingston, patriot or ocz, because they tend to use higher performance micron memory chips. Buying from these manufacturers also gives you the piece of mind that the memory card will be compatible, and the chip will be backed by their lifetime warranty.

I agree. Stick with the mentioned brands for high quality. Although, when i got OCZ, it seemed that my memory bay did get a little hotter that before (with standard HP memory, dont remmber brand)

 

Alright guy's, who exactly did you leave out? I mean you list so many. Off the top of my head you left out PQI and G.Skill. G.Skill as far as I know has PC5300 with the lowest CL, CL4 and not expensive. It was said any are fine, but should be expressed more clearly that the ones you recommend are simply nothing more than ones you have had good experience with. So in no way a negative on those not listed. Just a thought, I do see you guys making an attempt to be fair but could go a little further. I am also intrigued as that the GS with the lowest CL was not mentioned? Micron chip or not it is stable with lower CL? My opinions on RAM in more detail for those who are just learning, link. Oh and K-T add Elpida to your list then you will have all six DRAM MFG's in the world (yea not specialty MFG's). Any brand with a lifetime warranty should be good to go. I guess if we wanted to have a very short thread or one of the most biased. We could start one, "who makes bad RAM"? See my point?

 

I do not recommend Great Skill because it is not yet a well developed company. It is a step above generic brand, but it does not have the known reliability and performance as Corsair.
I am a very biased memory recommender. I usually always recommend Corsair, because that is all I use. I find that Corsair does manufacture the best memory cards, and I have never had a problem with any of their cards. Personally I like supporting american manufacturing, which is another reason why I go with corsair.
When it comes down to it, it is really personal preference. Any of the cards will be good, as long as they carry a lifetime warranty. It just happens that the Corsair memory works out to be only $1-2 more than Pqi, and I think that extra $2 is worth it.

even if gs is cl4 , won't it go to cl5 if ram in there already is cl 5 ? now if he is replacing all the ram it would be worth going to gs with cl4

 

You are correct and that would interject a new dilemma to the scenario. I was not mentioning for the purpose of a suggestion for OP just general thoughts. But good catch and you are correct. You ask what it matters? Good question. A lot of work has been done on this. If you have specific questions MOD John Ratsey is the best to ask. He has the most benchmarks. Funny thing is as much as PC5300 increases speed it also increases latency by the same amount. So not much of an improvement. Other things matter also. I have PC4200 that has bandwidth the same as PC5300 Santa Rosa, I have AMD.

 

I understand your points PP
PP, Dont you have your AMD overclocked ? If so that is probably why your memory runs so fast.
I have an AMD in my laptop, and the bandwidth of the PC3200 ddr memory is much higher than the Pc5300 in my intel systems.
AMD's rock, built in memory controllers are the best

Ktron i was just going to mention how my opty 185 and 175 with pc 3200 have better mem benchmarks than my pc 5300 mem in my intel comp , whats up with that ?

 

All recent AMD processors I believe Socket 462 and newer have a integrated DDR/DDR2 memory controller. The Opteron 180 you have and the 185 I have have a integrated ddr memory controller built into the processor.

Having an integrated controller helps to reduce the real challenges and bottlenecks of system architectures. This allows for optimized memory performance, balanced throughput, expandable I/O, and more linear symmetrical multiprocessing. This controller reduces latencies during memory access in a system, since the data does not have to go back through the chipset again like in an Intel system. It basically eliminates the need for a separate northbridge chip.

Plus DDR memory like PC3200 is clocked at 400Mhz.
DDR2 pc5300 is 667Mhz effective, but its really 333Mhz.
AS you can see 400Mhz is faster than 333Mhz
Even when comparing Pc3200 to DDR2 PC6400 at 800Mhz effective - 400Mhz, the ddr memory seems to yield a higher memory bandwidth, at least with the amd chip than an intel wth comparable speed ddr2 memory.

Integrated memory controllers are AMD's secret weapon, which all intel processors lack.
