Micron PC 100 vs Micron PC 133

[heng1028]

Why the price of PC 133 is cheaper than PC 100???
Which is more overclockable between this 2??

 

[paulip88]

Obviously the PC133 will perform better. Why is it cheaper? The gods must be smiling upon you or something. Don't ask questions, just take it while you can.

 

[TuffGuy]

i think that the pc100 is cas2, and the pc133 is cas3.

Click here and you will know the price of PC 133 is cheaper than PC 100.

I am just wondering how could this be?? Is that PC 133 CAS3 and the PC 100 is CAS2??I will phone them and ask them

 

[heng1028]

If the PC133 is CAS3 and the PC100 is CAS2. Which is better to get and which is better for overclock??

 

[office boy]

100Mhz Cas2 operates SLIGHTLY (VERY SLIGHTLY) faster then PC133, BUT running at 133Mhz gives better performance (go figure).

 

[Vegito]

Doesnt it depend on the speed of the chip also ? If you have a PC100 @ 6ns hehehe

PC 100 @ 8ns x cas 3 = 24 ns
PC 100 @ 8ns x cas 2 = 16ns

PC 133 @ 7.5ns x cas 3 = 22.5 ns
PC 133 @ 7ns x cas 2 = 14 ns

 

[heng1028]

Should I go with PC133 or PC100??

 

[office boy]

forcesho, You don't need 8ns chips to be PC-100 you only need 10ns chips
1000/10=100Mhz
1000/8=125Mhz
1000/7.5=133.33_

But the point you raise is a good one; a buyer should look less at the PC ratting, and more at the speed of the chips and their relative performance.

 

[heng1028]

The Micron PC133 is more likely be overclocked to CAS2 than some generic PC133. Is that true?

 

[office boy]

Hell just get PC-150
$105 for 128MB from Mwave

 

[lundog22]

Yeah I know Office Boy.

Those PC-150 TinyBGA are cheap and great.
I heard alot of people are getting great results with these babies (150 cas2)

 

[heng1028]

How good are they??

 

[lundog22]

They are great, here is an old thread KingMax PC105 TinyBGA

[office boy]

lundog22, Are they cas3? I've never seen where Kingmax has ever given them a CL rating?

 

[Vegito]

Oh I know, 1000/150 = 6ns, I forgot who posted it originally but learned it from someones here like months ago but Intel standard calls for 8ns for pc100...

 

[lundog22]

Here is a review of KingMax PC150 TinyBGA.
They ran some interesting tests and posted some results.

And here is KingMax's Website.

Like I said there babies can fly
...(without the high Mushkin price tag)

 

[office boy]

Thanks lundog22, they must have just added that features section (or I'm just blind )

 

[lundog22]

Office Boy how are they doing in your set up?

Cuz I am doing the same set up, just waiting for the T-Bird800, 256 of these RAM, and the Antecsx803 case.
Got the Asus A7V yesterday.

 

[office boy]

The ram's doing great running at 137mhz 2,2,2
I just wish I knew what was holding my FSB back, It won't go over 105 :frown:

 

[lundog22]

hehe shouldn't complain too much since your Duron 600 can do 1081.

 

[MSNY]

I have Micron PC100 and its CAS2...

 

[heng1028]

I will go get 2 stick of the Kingsmax PC150 at mwave.

 

[heng1028]

damn it... i was going to order 2 sticks today but the shipping fees cost half of the price of the ram to canada?? how could this happen?? it is just 2 sticks of ram. is that very heavy or what??

it is 98 bucks now... go get some before it is too late..

by the way, how much did you guys in US pay for the shipping????
It seems high for the canadians

Geeez Heng...by the time this thread fizzles out, you should make it to senior member without saying one intelligent thing. All of the questions you have asked are easily answered with just a smidgen of reasearch on your part.
