just want to know are there any significant differences btwn using 1 x 1Gb RAm & 2 x 512 Mb ????
According to apple site , it' best to use up the 2 slots so taht the dual memory channel can perform at its best. Has any1 feeel the diff ???

it's depend how affordable u r also...
as long both ram sticks are 667mhz...

i know.. now i m planing to get a 1gb 667 1. then maybe later upgrade another 1 gb stick. jsut wondering if i use just 1 stick , will the performance be not as good as 2 x 512 ??

I would suggest you to get a standalone 1Gig Ram rather than 2x512MB ram. This is because later when you wanted to upgrade to 2 Gig, just slap another 1Gig would do. Dual Channel or single channel doesn't matter. It dont really makes much difference. I think it's more of a marketing gimmick

Get the 1Gb and slap it in for total of 1.25Gb. Its good enough AND upgradable.

I've been using this setup for few months, yet to upgrade another Gb cause rarely use that much memory. Hehe..

BTW, who knows what brand of RAM offered by other party supported for MB??

Can v find those 3rd party non-apple certified RAM that can run smoothly on MB easily in Penang??

if u dont plan to upgrade the memory in future anymore.. than get 2 x 512mb to enable the dual channel.

dual channel is like - two way two lanes motorway

single channel is like - two way but one lane motorway

hence dual channel can afford more transfer, more capacity, more efficiently.

but if u plan to upgrade ran again in the future, then get 1 x 1gb first to save up the slot for next time

ya i do plan to upgrade again later. jsut that 1 shot cmoe out with RM800 abit too much for my wallet to handle.

if u plan tat ur total upgrade will be 1gb only, then get a 512mb first and get another 512mb next time when u got the cash again.. at least when u hv the total upgrade of 1gb, u can hv it running dual channel..

else throw much cash now for a 1gb and upgrade another 1gb ram or 512mb next time if u need it. but if u put 512mb next time, u wont hv the dual channel stuff.. which is not really important if u a lot of memory..

rhesusv..

if u r on the macbook, i think u need two of the same size rams, i.e. 2x512 or 2x1GB... it's dual channel... i heard the macbook does not boot or does some weird shit if only one slot's occupied...

U can give it a go... mayb the new core 2 duos allow tat... gd luck...

Its not a marketing gimmick . these ram and mainboard call them dual channel memory slots for a reason. its actually slower to have a machine with 1gb compared to 2x512 - there are tons of writeups on the net- go look for it.

I think everyone knows that, and that you cannot leave one slot empty. Just pop in the 1GB coupled with the existing 256MB for a total of 1.25GB. The upgradability of this setup is worth more than the speed improvement of 2X512MB setup.

if you are talking about the same amount of memory...i'd say dual channel memory is better at least under the benchmarks... but it might not be that much noticable...i'd opt for the 1 x 1GB upgrade as many here is correct as you do not have to sacrifice the 2 x 512MB in the future... furthermore... 1.25GB is more than 1GB even if it is only 256MB more.. and don't forget the macbook takes up another 64MBs for its built in display adapter...

just make sure you get the same memory in the future you get now to better optimize it... as DDR actually states that you should get a dual channel kit...which is more expensive than buying 2 separate pieces...

there are Kingston KTA memories available for around RM550 i think rather than the usual KVRs...

i c... so both slots must be occupied then.

btw , civic 98 , so far yr 1.25 has no prob at all right ?? what ram are u using? coz i m planning to get the mushkin 1gb coupled with the stock ram. no prob right ?

better use 1gb indeed of 2 x 512mb

I'm using Corsair, no problems but there are people here against Corsair, maybe I'm the lucky one.

I think Kingston RAM prices came down, the 1GB is less than RM350 if not mistaken, while Corsair is still around RM395.

but i heard right ? Kingston is not that good. Some apps maybe not run smoothly. how come ppl are agaisnt Corsair ?? i though Corsair is 1 of the leaders in the RAM market.... :|

It's not that it's not good, just maybe not really compatible with the motherboard.

RM350 .. is kinda cheap ...

am looking to pop in a 1GB after CNY ..... but also wondering what to buy (as long as no compatibility issue.. performance wise, i don't think it is really noticeable)

1 more is dual channel is on,you will get extra marks in pcmark lol...

If I were you, I would pop in 1 x 1GB first, then another 1GB when I have enough money. It's hard for me to earn money so have to spend wise

hai,

Does the RAM mention above compatible with Mac Mini ( intel chipset )? Any idea where can i source those RAM?

Thanks.

now Im using 1x1GB 667mhz by corsair replace to 256mb x 2 on my Macbook. To tell the truth, using 1 slot show much slower performance than using both of it. Agree?

but using a 512mbx2 u have no choice but to have the max cap of 1024 mb ram

1gb ram can add aditional 1gb ram so it will be faster

Just put in one 1GB and leave the other 256MB there, nothing wrong with it. In total you have 1.25GB which is pretty good!

hahahaa...1 shot 2 gb is really taxing for most ppl. btw , i think like wat civic said just pop 1 gb in 1st together with the stock ram. then later only get the other 1gb .
Currenly with the stock 512 mb , ifeel the speed is still fine if there's no multitasking. if there's really multi tasking, i can really feeel the need for waiting.

Will pop in a 1gb by next week .

Well, actually, the performance of dual channel will be more significant if you use it in MacBook or MacMini which uses shared graphic. For iMac or MacBook Pro, seriously, no difference.

is the differece really that big until i can feel it ???

Yes, if u have 512mb ram only, u can feel the difference of its running in dual channel or single channel..

but if 1GB ram and above, you wont feel much different unless u run heavy applications + multitasking a lot of time.

dual channels works best if both rams are of the same model chips...
similar to dual channel performance ram for PCs bundled together...

but one shot 800 bucks pokai lor.....
i'm usin dell insp 6000 dual channel wif 1Gb + 256Mb....running fine...
u wan faster boot time... use apps to load boot/startup/system files on memory...

even so, wen i upgrade to 2Gb, i'll sell my current 1Gb and get 2 new 1Gb sticks.... definitely minimize compatibility issues....

sayin tht i feel like wanna get a new laptop altogether....heheheheh....

mac os x boot time is fast enough.. c.f. to windows XP.

so you mean that if i use a 1gb + 256 mb ram will be faster than 512mb x 2 ???

I just upgraded mine to 2GB. No diff compared to my previous setting 2 x 512mb setting, except for the photoshop la.

Ofcourse la...
Imagine a highway that have 5 lanes, but only have 10 cars....(2GB)
Then imagine a highway tat have 2 lanes, and 10 cars (512x2)

Anyway...back to the question...
1GB logically will run slower than 512x2 dual channel......But u can hardly see the difference......
And no matter what, i will advise u to get 1GB instead for 512x2 if u have intention to add until 2GB later time, it will be more benefit....

the extra 256mb does have extra advantage.

since there are only two slots, go for 1gb ram, then next time u can upgrade again if u feel not enough.

hey guys. i just bought a kingston 1GB from lowyat (the shop at the back on IT floor that sells macs). he convinced me to get the KTA RAM for mac which costs RM630.. much more expensive than the normal ram. he said the performance is much better..

I've paid of course but i want to know if it's true or he's just bull shitting me. anyone care to clarify?

This post has been edited by seok: Jan 31 2007, 01:46 PM

wow... RM630 for a 1GB RAM. That's pretty hard for me to swallowed....

You should ask him whether the 1GB KTA is faster compared to 2GB normal RAM, cause at that price you could have bought 2GB.

Ouch.. Guess you been cheated/punk

he said KTA is more stable for Mac.. value ram crashes a lot especially with heavy tasks load like photoshop/final cut/etc..

true true??

*sob.

Dont worry about it, KTA is priced higher for a reason, you bought it and now what you need to do is ENJOY it!

I assume yours is for Imac / Mac Pro? I dont think they have KTA notebook RAM right?

no I'm using Macbook.. and it's KTA notebook RAM that i bought.

Yeah u're right i should enjoy it instead of whining how much overpriced it is. anyway i'm also wondering if i were to buy another 1GB later on, do u guys think it's ok to use one KTA and one other brand ram, such as corsair etc..? or is it better to use 2 same brand? am currently running 1.25GB

Dude, if i were you, I'll just standby one empty slot for expansion, it's common sense.
Why wanna trouble yourself later knowing that you wanna upgrade to 2GIG later?

well i am. now 1 slot is 1GB and 2nd slot is 256MB. so 1.25GB all together.

so far no crashing and quite big improvements. haven't tried playing games but i'm sure it'll be alright.

It's better to use same brand if you want get DualChannel (64bit). Another alternative, you need get same speed ram(other brand) as your KTA for DualChannel to work. Sometimes with other brand, you still get dualchannel running. Or if you don't mind about dualchannel stuff, just get other brand as it much cheaper than KTA, unless you're rich

He IS rich, he just bought 1GB RAM for RM630! Hehe.. Be rest assured he is enjoying it! The next question he needs to ask is the 2nd piece, should he get a KTA or normal.

My guess is, NEITHER. 1.25GB is enough (well for me) 2GB RAM doesnt necessary help out in games due to max 64MB video memory. What I realised from my setup is I rarely use all 1.25GB of it.

YA..

Need ask him whether got use parallels or some app(photoshop) eat lotz memory. For me, definite need 2Gb cos' parallels

i think an 1 gb ram is bter...i read them somewhere else..it said that it is more easy 2 acess the memory usin 1gb ram stick...i myself use 1gb ram instead of 2 512mb stick...

hey guys. well i'm using my macbook mainly for photoshop and internet.. little bit of games. so far i think with the new RAM photoshop is definitely much faster. i don't use parrarel so it's ok.

yeah guess i'll stick to 1.25 for now. and i'm not rich.. just stupid!

great reviews i read over here. thnx guys. gonna pop in 1Gb
