168 Pin or 184 Pin RAM?

[yELLOthar]

Well, my A++ teacher (whom I doubt is even certified himself...) claims that 168-Pin RAM is far more popular than DDR 184-Pin RAM. He then goes on to say that it is far to expensive for "everyday use", and that Rambus is the only ones who make it. Naturally, I couldn't help myself. With the release of DDR3200 512MB sticks, for only $40 (Rosewill), he is full of crap. Honestly, I don't know of anyone who still uses 168 pin, maybe it's just where I live?

All I know, is he is using an outdated book (any book on computers gets outdated quickly...) and we are "learning" with 166MHz Pentiums and 16MB 72-Pin SIMM memory. Honestly, I despise that class. It's so stupid...

IIRC, 168-pin is SDRAM.
184 is DDR
200 is SODIMM DDR
2xx is DDR2

SDRAM is old and getting more expensive as it's no longer in mass production, supply/demand etc.
RAMBUS RAM is different to SDRAM, and has different slots.

Tell him you will sell him all the DDR 512MB DIMMs he can use for only $75 each. :laugh:

168 is SDRAM.
184 is DDR (Double Data Rate) SDRAM

I know those two for sure, but I don't know much about SO-DIMM and DDR2, but isn't SO-DIMM used in laptops? Either way, my class sucks

And yes, RAMBUS is RIMM. So it does have it's own specifications. He, however, said the only 184 pin RAM was RAMBUS RAM!

 

[yELLOthar]

Heh, I should try that. But he uses a Dell anyway, so he probably wouldn't know how to install it >_<

just go up to him and say screw urself

It's fancy Sunday church-goin' RAM? The good RAM for when you have company over?

I would rather not get a detention this early in the school year

168 = SDRAM
184 = DDR
200 = SODIMM DDR
240 = DDR2

I think your teacher is a bit behind the times.

Your teacher obviously doesn't keep up to date.

SDRAM=168 pin, old, slow, and actualy more expensive since it's not made anymore.

DDR=184 pin, mainstream, good prices for now until DDR2 becomes more mainstream

DDR2=240 pin, currently used only by Intel, higher clockspeeds, but also higher latency

RDRAM 16bit = 184 pins, keyed differantly than DDR, high speed, bad latency, serial interface, used by intel 850 chipsets, had to be used in pairs

RDRAM 23bit, 232 pins I believe, ASUS P4T533 was basicly the only motherboard that used it, 850E chipset.

Rambus did not make DDR, they made RDRAM, which was much more expensive and SDRAM was mainstream at teh time, but that was like 4 years ago, so your teacher is a little out of date. DDR is SDRAM that runs at double data rate as others have already said.

sdram had a point where it was really cheap.. and yes thats true it is actually rising in price, it's pretty crazy.

all you have to do is this.. tell him to visit pricewatch.com and look at the widespread ram pricing for himself

Or you could just remind yourself that he's a tool, pass the class and forget about it.

Give him the link to this thread.

Tell him DDR can be used for special occasions also.
Like when he has a hot date with one of your classmates that just happens to be failing the class. :laugh:

Amen.

Tell him to stop living in 1993.

I love seeing teachers who teach that class. I don't see why anyone would take that class, when they should be able to pick up just about everything with everyday computer use. (at least if you do anything constructive with your computer)

The only thing that anyone on these forums should need to pass the A+ test is a $40 book to get a few of the particulars.
