I guess system bus 1033 is
more than enuff for me. If I'm buying AMD Phenom IIx4, i think I've
to use only AM3 which is backward compatible with ddr2
ram.
Hmm, the type of ram that can be used is usually depended on the
motherboard's design. My board supports ddr2 and ddr3, but some of
my friends tell me that these kind of board tend to spoil easier
due to different voltages(i cannot confirm about this). DDR3 and
DDR2 rams runs on different voltage, different speed and timing
A normal ddr2 ram runs at 667-800mhz. Meaning it can run at that
speed. But it can read the data and use them normally at 6-6-6-18.
The number basically means how the amount of time taken for the
data to pass from one section to another in the ram, and the time
taken to utilise them. Of course, we want the timing to be as short
as possible(Like ping, or your response time)
A ddr3 ram runs faster, which is around 1333, but the timing
will be higher, about 9 to 10. However it does make a slight
difference in speed, i can't really explain into detail because i
really don't know about it.
When you buy rams, sometimes the salesperson will say that both
the ddr3 runs at 1333mhz, but one runs at 9-9-9-24, while the other
runs at 10-10-something. Unless you are really an overclocker to
squeeze out all the juice, i can say there you 'cannot really feel'
the difference between the two of them in normal operation
Also, sometimes they will try to get you to buy rams with nicer
packaging, or with heatsinks, and tell you gamers uses this to play
games etc. This kind of ram are more expensive because you are
paying for performance(and of course the nicer packaging etc).
Remember i said about ddr3 running at 1333mhz, with timing of
9-9-9-24. THe more expensive ones that they might as you to buy
will be the rams that are capable of running at higher speed with
shorter timing(you can think of it as response time). They also
comes in dual channel or triple channel kits.
WHen they try to sell you kits, it meant that the rams are
tested one by one(tht is what i tell people to get them to buy the
ram, but im not sure if they really does it), and after that, they
group ram of similar or near exact performance together and sell
them. In this way, you can run them optimally in dual channel or
triple channel mode. Dual/triple channel generally means that there
is more bandwidth for processing
Unless you are really overclocking, there is not a need to buy
very expensive rams
Yes, have to agree with you,
Kingston is value for money. In the past went to the distributor
once before, services not bad, no complaint from me.Corsair rams
never heard or try before, not too sure if its good &
stable.
I am using corsair rams, if i am not wrong, most people
associate corsair with their dominator series(which is a high end
ram series), however they also have their value rams. Kingston have
their high end series, like the hyper x series
Corsair is not bad, but if you are familiar or have more faith
in kingston you can stick with it(sometimes it is weird but i will
say get something you are familiar with.Like sometimes you want to
try a new dish in the rice stall, but scared it might taste
bad)
Didn't know that hardisk have
cache, noted again, thanks.
Hmm. You need to understand how hdd work basically. The data is
stored on tracks and sector(Like in hdb, floor and unit
number.)
If let say the data(or program like photoshop) u used most
frequently is stored in track 3, sector 1(Or your best friend stays
on 3rd floor, unit 1, and you always go there and drink coffee with
him)
Cache now is like a memory, because you cant expect yourself to
look at the phonebook to find out which unit your best friend is
staying at evertime you want to find him. After going to his house
a few times, your brain 'remembers' the location
Same in computer, the hdd knows that you go to that location on
the disk frequently, they will store the info on the cache.
And when you start photoshop next time, the hdd will not have to go
to search all around for where photoshop is, but it will go
straight to track 3 sector 1. It is like you memorise where your
best friend stays, and u can go straight to him. Thus, there is
less waiting time
I thought if I buy the AMD
processor, it only comes with the processor right ? how come got
heatsink & fan, i'm quite puzzle abt this.
Ok, this is like buying a car. When you buy a car, it comes with
a default radio.
When you buy processor, it is the same thing, it comes with a
factory built fan that is designed to cool the processor at normal
operating speed.
When you want to use it at its defaulted speed, or overclock it
a little, the design of the heatsink will be able to dissipitate
the heat quite effectively.
Like the radio in your car, you can turn the volume up a little
more to listen to your favourite song.
But if you want to listen at loud volume, with better bass or
subwoofers, you need a better headunit with more watts or a power
amplifier. If you keep on blasting, maybe it will cause
damage
Same as the processor, if you want to overclock it, you have to get
a better heatsink+fan(HSF for short in some forums), if not it will
cause damage
3rd party Heatsink fans can be bought in sls, just make sure it
supports your cpu socket.(meaning the mounting given in the package
must be able to fit your motherboard to cool the cpu
efficiently)
that is all i can think of now
