No it does not. PC2100 is DDR memory (Double Data Rate). It performs 2 writes per clock cycle. Basicly it works twice as fast. PC100 memory only writes once per clock cycle. Also the only way you can use both is if your motherbaord supports it, but only one or the other.
And while we're on it the only way anyone will get the benefit of PC2100 memory is if their CPU is running at 266 FSB (Front Side Bus). If not then it will run at PC1600 speed which is 200 FSB.

That's right.

It was a joke

ack.. and it's not running at 266... i can't figure out how to get my FSB higher than 133 hehehe

In your bios it will say 133 but as it works twice per clock cycle it doubles up and becomes 266.

so my processor IS actualy working at 266 FSB? it's all tied into the RAM?

If you are using PC2100 DDR RAM then, yes your system is working at 266 FSB.
To complicate things futher, some motherboards allow you to set the memory speed as well. If yours allows this make sure that it is set to 133 too. If it does not then it probably has already detected it so do not worry.

Hope this helps.

one question, why is the jump point so flat? shouldnt it be a tunnel?

And Crusade/ACTA shows jump points as flat from the side, but long when you look into them.

And then there's the physical problem that DDR RAM is 184-pin and regular PC100/PC133 is like 168-pin ... so they won't fit in the same slots.

By the way, RAM speed and FSB speed are not necessarily the same. The original KT7 ran the memory asynchronous from the FSB; that is, FSB was 100MHz and it could run the RAM at 133MHz. The KT7A allowed for 133/133 (as well as +1MHz increments for both RAM and FSB, for example my KT7A board ran with the FSB and RAM very happily at 140MHz.)

DDR RAM does not run at 266; your BIOS is correct in displaying 133, but because it can take action on both the rise and the fall of the clock cycle (think sine wave...imperfect analogy but whatever) it gets twice the work (hence Double Data Rate) out of one cycle.

So anyway ... Coconut Joe's right about the rest of it though

....forget to read my post there, Kazan? Good point about the RDRAM though. Too bad it's got horrible seek times and prices. :shrug: Oh well.

Im Jealous of all you people. I have to get by with an AMD-K6-2 500 MHZ, 88 megs of RAM( dont ask about the amount of RAM, its a long story), and no AGP slot.

Heh. I'm currently on something like Tomcat's - K6/2 400, 96MB RAM (EDO no less...) an 8MB Voodoo2 ...

Currently, that is. Just wait until the 2nd.

(And it's not even my computer. Whee!)

My computer, on the other hand, is killer because I paid money for it to be so. Sorry guys.

While were on the subject of pictures and hardware: I'm looking at getting a new video card and I was wondering if you guys could give me a few suggestions about what the best video card I could get for less than $100 and that is PCI would be.

OR should I go for more RAM.

Yeesh I hate making these kind of descisions.

Anyways any input would be welcome.
