oh.. cooll sumthing i learnt.

well how do we check the speed of the ram?

and another question.. how do i make sure the windows given to me is the original one?

Its limited to DDR2-667 because of Athlon X2, Turion can go 800, but the speed difference is insignificant. Mine comes with 800MHz, but you can mix memory speeds, which it will run at lowest speeds. You can either use CPU-Z or physically see the RAM module

Checking authencity of Windows? Usually they give the CD AFAIK, at least a recovery CD, but most k40AB is FreeDOS

oh.. so.. the processor determines the speed.. well.. basically da turion will run better with the aid of faster ram but athlon processor runs faster but with a slower ram which makes them even?

a recovery cd as in the windows one? well.. its most probably a freedos.. and when they install.. i wont know if its the ori or pirated one..

does purchasing the laptop come with the driver cd?

No, don't get mixed up, the Turion are supposed to be the 'Phenom' of the laptop, so they are better than Athlon, they have larger cache, more P-States to give better power saving and support for faster memory. Forget about it since it only comes with A64 X2 QL-64 anyway

Most probably they install pirated one, unless you asked for them for OEM one, I don't know how much does OEM costs, maybe RM300-400?

Yes they do give the driver CD, everything comes with driver CD, they don't expect people especially people with zero knowledge of PC wandering around the web looking for driver

lolz.. so Turion will be a much better offer.. but wonder why its not available in malaysia.. uh.. any chance there will be ppl offering turion in pc fair? a singapore company? lolz..

i have zero knowledge on the processor stuffs.. haha.. all i know turion saves mroe power and cooler eh..

well.. rm300-400.. it cost quite a sum eh.. i guess.. im left with pirated vista as choice..

Careful, be clear on your " vice versa " statement. some ppl will thought that if K40AB is slower and the guys ram faster, it will run in faster speed then. which is not true


"RAM will always select and apply slower memory frequency on both memory module"

this is a better statement. System will always run on slower speed if ram modules are found different in speed.

you cant feel the difference in real life imo

well that's true. that's what happen with my rig which i OC ram bought quite some time DDR2 667 to DDR2 800 ( to be parallel with OCed cpu ), which in the end " NO FELL ", LOL

well, Turion is more like the higher end of desktop Athlon, while mobile Athlon is the lower end of the desktop counterpart, to be honest...

AMD still dun ve any K10 mobile CPU till a few mths later, when the Turion II and Athlon II comes out...

anyway, for AMD, the CPU type determines the max RAM speed u can use, since the memory controller is built into the CPU, where for Intel, the FSB of the CPU is the key as memory controller is located on the mobo...

ahh i see.. so those labelled of 667 and 800Mhz in the processor are those indicating the ram speeds.. cool

so from the brochure i gotten from ASUStek in midvalley.. it says 800Mhz so the ram shud be running in 800Mhz.

and ram can be overclocked? according to Someonesim??

and "anyway, for AMD, the CPU type determines the max RAM speed u can use, since the memory controller is built into the CPU, where for Intel, the FSB of the CPU is the key as memory controller is located on the mobo..."

tat means only AMD processor determines the ram speed while Intel processor leaves the job to the motherboard?

and last of all.. it shud be impossible to get a turion version in malaysia rite? probably.. 1% chance?

whichever RAM speed u can use, it's all determined by wat the memory controller supports...

for Intel, it's still going the old way, where the controller is built into the motherboard... so whenever u change CPU, the same type of RAM is still supported... (eg PM45 chipset, it supports DDR2 of up to 800MHz and DDR3 up to 1066MHz iirc, no matter u use C2D or Pentium Dual Core, these RAM still can be used) but for Intel, they go by the FSB (Front Side Bus) way, which u can see as the speed at which the CPU communicates with the RAM... a slow FSB can be limiting the max RAM bandwidth avaliable, and vice versa...

for eg, C2D 1066MHz FSB (real FSB 266MHz), RAM running @ 533MHz DDR (real speed 266MHz) is already sufficient, anything more is fine but wasted since the FSB cannot run as fast unless u overclock... putting in 400MHz DDR (real speed 200MHz) is fine too, but the RAM's speed will become bottleneck instead since it cannot catch up with the FSB... so yeah, dun listen to all the DDR3 bullshit, those are juz marketing gimmik...

for AMD, their memory controller is built into the CPU, so everytime u change the CPU, u re changing the controller as well, those affecting the RAM type that u can use... for Athlon x2, it supports only up to DDR2 667MHz, while Turion x2 is DDR2 800MHz... so for Athlon, even if i put DDR2 800MHz into the laptop, the RAM will still run at 667MHz since that is the max speed that the memory controller in the CPU can handle...

hope this make things clearer...

its clearer now. hahaa. thanks bro.

hmm. well whats the real diff of DDR 2 and DDR 3 then?

from the brochure i've got. it says the athlon processor is 800Mhz?

is there a typo or what?

Generally DDR3 > DDR2 - Its memory speed

Think of it is BMW 3 series (DDR2) vs BMW 7 series (DDR3). Generally DDR3 is faster , and it just beats the crap out of DDR2 - in terms of power consumption , speed and such

oo.. the speed in Mhz rite?

but with the processor FSB running at at 667 or 800.. the DDR3 lets say its 1066, its fairly useless rite?

can i know the memory type of the k40ab 4570? cant find it

is it DDR2, DDR3 or GDDR3..

it shud be DDR2 according to the AsusTek brochure i gotten from midvalley

actually DDR3 and DDR2 can have good performance gap, but due to some issue now still no fair increase. issue like speed, common DDR2 ram can bought likely DDR2 800 to DDR2 1066, while DDR3 can be bought was DDR3 1333 to DDR3 1600 ( without consider those extra-expensive one ) see the difference of speed ? little !
another issue was what being previously argued. FSB speed. no matter how fast you ram are, still cap by bus speed ( FSB for convention intel cpu, HyperTransport for AMD, QuickPath Interconncet for Intel Core i7 ). Obviously from Intel's Core i7 changes, you can notice DDR3 cant smoke DDR2. In fact Core i7 introduce triple channel ram so ram bandwidth can be triple ( instead of double in DDR2 ) to eliminate ram bandwidth bottleneck.

DDR2. And yet you include GDDR3 inside which was impossible since is a graphic memory type.

means it all depends to compatibility.. between the processor FSB with the ram..

a higher ram with a low FSB is fairly useless.. correct?

Yap, like when you put turbo to Kancil, still lousy car mah ( sorry for all great kancil owner )

for Intel laptops, high FSB with low RAM speed or vice versa is bad... best is when FSB and RAM are of the same speed...

for AMD, it's all abt RAM speed... the faster RAM u ve, the more bandwidth u ve... that's y gamers and servers would like to use AMD also...
