so my corsair pc3200

[Bobo]

Ok first off you just proved me right by sayin that the ram is doubled pumped which is what i said from the start.

Of course it is double pumped. 100MHz x2=200MHz. DDR400 chips originally run at 100MHz, but because they are double pumped, they run at 200MHz.

2. Yes it is DDR500 250mhz x 2 = 500mhz that is why they call it DDR500 and not DDR250, duh.

Where are you getting this idea that DDR500 exists? Unless you OCed it to that speed, of course, which is quite possible. DDR500 runs at 250MHz.

3. You denied that the ram was double pumped and now you are sayin it is?

I never denied that it wasn't, I just denied that what you are saying is right, because of course, it is wrong.

And what point exactly am i missing?

The fact that you are totally wrong. I am not going to bother to post the Wikipedia article again to prove to you a third time, because if you are stupid enough to think that the rest of this forum and I are wrong, then you need to go to a mental institute.

Well, thats enough for now i have to go back to work.

About time.

They actually sell DDR500 memory on newegg, however technically it's just overclocked DDR400 RAM.

Single Channel:
64bits (interface) x 200MHz (frequency of the RAM) x 2 (Double Pumped) ÷ 8 (8 bits in a byte) = 3200MB/s ~= 3.2GB/s or PC3200

In dual-channel:
128bits (interface is doubled, not frequency) x 200MHz (frequency of the RAM) x 2 (Double Pumped) ÷ 8 (8 bits in a byte) = 6400MB/s ~= 6.4GB/s

OK, that is what I figured

Single Channel:
64bits (interface) x 200MHz (frequency of the RAM) x 2 (Double Pumped) ÷ 8 (8 bits in a byte) = 3200MB/s ~= 3.2GB/s or PC3200

128bits (interface is doubled, not frequency) x 200MHz (frequency of the RAM) x 2 (Double Pumped) ÷ 8 (8 bits in a byte) = 6400MB/s ~= 6.4GB/s

THIS IS RIGHT. PLEASE LISTEN TO REASON.

Yoi and double yoi......

Ok well im done arguing the point cuz you obviously dont understand and i wish that someone else with knowledge would back me up on this.

But if you really wanna think that every single RAM company lies about what they are selling, then you believe that. I was just tryin to help someone understand what DDR is. No, i dont know EVERYTHING about DDR but i know alot, and obviously alot more then you.

Oh and another thing, what was just posted compares single channel and dual channel DDR, that has nothing to do with the speeds just the bandwidth. Thought you might wanna know that. Yes, comparing dual channel ddr to single, it is only the bandwidth that is doubled (in my case it only went up from 2.2gb/s to 3.2gb/s so not really doubled but hella better) . But would someone like to tell me what that has to do with anything we are discussing? We are discussing that DDR is double pumped multiplying the clock speed by 2. And it doesnt say that DDR400 chips are 100mhz, it says DDR at 100mhz, there is no 400, so it is most likely talkin about DDR200.

Would you still like to explain to me then why every DDR400 ram says it runs at 400mhz? Or it will say 200 x 2.

I dont understand why you can't understand this...

Straight from Wiki.

This is turning into another Grapejuice fight.

Im not sure if you guys can read what im typing or not, but as it ALSO says in that site, if you would read, it says that the ram is double pumped which we have gone over and over on this and you still arnt getting it. 200mhz x 2. Its not that hard of a concept to understand. I understand it all just fine, they are posting the actual clock speed, not the multiplied speed.

And bobo iv seen your track record of being right and i gotta tell you it doesnt look very good.........

In any case, i DO know what im talking about whether any of you understand what i am trying to say i will make it as clear as possible

DDR400: 200mhz(clock speed) x 2(double pumped) = 400mhz Hence the name DDR ****400***** not DDR200. I would think that the ppl that actually make the ram would know what they are talkin about when they label it DDR400. I really cant clear it up anymore then that.

I dont understand why you can't understand this...

hey i need to chime in, just because its said on wiki does not make it true, anyone can post on that site

 

[TheChef]

I know anyone can post and I've seen stuff that's completely outrageous....

but that is true.

Good point, kgod.

I would think that the ppl that actually make the ram would know what they are talkin about when they label it DDR400

or they're trying to sell it

There is a simple way to do this. Download CPUZ and check your memory frequency...

Ok well im done arguing the point cuz you obviously dont understand and i wish that someone else with knowledge would back me up on this.

It seems that everybody (whether or not they have any knowledge, but I won't get into that) is backing me up on this one.

But if you really wanna think that every single RAM company lies about what they are selling, then you believe that. I was just tryin to help someone understand what DDR is. No, i dont know EVERYTHING about DDR but i know alot, and obviously alot more then you.

Well #1, a lot is 2 separate words. #2. The pronoun I is capitalized. #3. No RAM company is lying about what they sell. #4. You may or may not know more than I do about the RAM itself, but in this case you are dead wrong.

Its not that hard of a concept to understand.

Which is why I just can't figure out why you don't get it.

And bobo iv seen your track record of being right and i gotta tell you it doesnt look very good.........

Oh really....you have been here for not even a month, and I have been a member for almost 2 years now. Sure I have been wrong before. But personal insults aren't really a good idea, especially when you are on the losing side.

DDR400: 200mhz(clock speed) x 2(double pumped) = 400mhz Hence the name DDR ****400***** not DDR200. I would think that the ppl that actually make the ram would know what they are talkin about when they label it DDR400. I really cant clear it up anymore then that.

Why do you keep trying to explain it incorrectly when Wikipedia does such a fine job?

Chip specification

* DDR-200: DDR-SDRAM memory chips specified to operate at 100 MHz
* DDR-266: DDR-SDRAM memory chips specified to operate at 133 MHz
* DDR-333: DDR-SDRAM memory chips specified to operate at 166 MHz
* DDR-400: DDR-SDRAM memory chips specified to operate at 200 MHz

Wow....I think we are going to start calling you grapejuice from now on.

*edit* just saw this:

hey i need to chime in, just because its said on wiki does not make it true, anyone can post on that site

So here are some more sites that explain it:

http://arstechnica.com/guides/askars/ask-ars-20040710.ars
http://www.archmemory.com/index.asp?PageAction=Custom&ID=45

The RAM is NOT, I repeat, NOT running at 400MHz. It is running at 200MHz, but "acting like" it is running at 400MHz, because it is dual-pumped. Do you get this? It is "acting like" it is. BUT IT ISN'T ACTUALLY.

"At roughly the same time, faster memory, in the form of DDR (Dual Data Rate) RAM, hit the shelves. DDR is a type of memory where data is sent over the bus at twice the speed of the clock. A 133MHz bus behaves like a 266MHz one would and the memory used on this bus is known by the higher speed, i.e. DDR 266." Thats from your first source which proves me right once again.

We are goin in circles here. You dont seem to get it, and im not gonna sit here for months tryin to get you to understand how DDR works. I know how it works, thats all i care about.

Also, im not sure if youv counted lately, or can count period, but if by everyone backing you up you mean a whopping 2 ppl, then yea, i guess "everyone" is backing you up.

And why are you correcting my grammer? Are you really that worried about it? Cuz im not.

Do you not see "behaves like"????? IT IS NOT 266MHz. IT BEHAVES LIKE 266MHz. There is a big difference there.

I understand how it works perfectly.

Also, im not sure if youv counted lately, or can count period, but if by everyone backing you up you mean a whopping 2 ppl, then yea, i guess "everyone" is backing you up.

Because nobody else cares about whether or not you understand this.

And why are you correcting my grammer? Are you really that worried about it? Cuz im not.

Because you were commenting on how you were right and I was always wrong.

 

[{LSK} Otacon]

This is the last time im gonna prove to you im right, if you wont give up now then i will, cuz i really could care less if you know how it works or not.

http://www.legitreviews.com/images/reviews/69/label.jpg

Do you see where it says 400mhz? Tell me why it says that if its not true. If they were saying that and its not true, thats a lawsuite which companies like that wouldnt risk. Im not sure why you cant understand it. But after this i give up. That would be like Intel tryin to sell cpus that SAY they run at 2ghz when really they run at 1ghz. Doesnt make sense does it? And its illegal.

 

[TheChef]

Download CPUz and see what your RAM is running at. That should tell us everything we need to know...

 

[{LSK} Otacon]

I already know what cpu-z says, im not stupid.
