KDS Mini RAM?

[AuraEdge]

I went to a comp show recently and asked to look at some RAM 128MB 168 PIN DIMM for NS ratings. Well some of them were from a company named KDS, and the chips on the RAM sticks were smaller than normal (like micron or something). When I asked about them, they said it was 'new technology' and it was the 'cheapest' you can get. Is this ram shady, or are they ok?

The memory in question is based on a new memory manufacturing process called "ball grid array". I don't know the exact timings, but it is supposed to be moderately fast, plus it is cheap to make. I believe Kingston was the first to use this process. As for its o/c'ing capabilities, I don't now, since I have yet to try it.

The reading on the chip was 8ns to me. Doesnt seem like much is different besides the size of the RAM chips on it. Is there anything to be aware of if i were to purchase this stuff?

Hey, remember, 8ns can mean the speed of the chips on the stick, or just the speed of the stick, if they are both 8ns, then it would be pc133.

EXCUSE ME?
Theres no numbers on the stick
Just on the chips!
and PC133 is 7.5ns or less (1000/7.5)

[KillerBug]

Ok, 7.5ns, but since 10ns runs at 133mhz, (not officialy), 8ns will go way past 133mhz.

ok so the physical limit of my 7ns pc100 128 megger would be 142 mhz??(1000/7)??

[AuraEdge]

They call this Thoretical limit. The NS ratings are givin as how long it takes to complete a cycle (as labeled). If it can complete 1 cycle in 7ns, then it can complete 2 cycles in 14ns, and complete 142 cycles (mhz)in 1000ns (1 second). Again..this is only as labeled. (like Celeron 300a..hehe). Anyways some will go past that number, but PC133 is really nothing more than 7.5ns or less. A smart RAM shopper would look for low ns rating instead of PC numbers when shopping for RAM (I do...). There is usually a markup on PC133 RAM as opposed to 7ns PC100 SDRAM, which I believe are very similar. Heck I got some PC66 @ 6ns running at 142Mhz FSB.

thanks for the tip on puchasing ram auraedge. I still say you've either got pc66 on steroids or its possessed.
