PC3200 200Mhz??

[Play4Fun]

CPU-Z shows me that my memory card got only 200MHz (pic below), can it be true? I got PC3200 so it should be 400MHz right? ;\

What is your bus speed for your mobo / CPU? I am pretty sure it will only go as fast as the slowest link....

 

[ailevation]

:O Oh crap... my SiSandra says that I am runnin' 200 Mhz x 2 so, 400 Mhz, should I be at 400 x 2 or something?!

 

[rammstein]

Haha

Remember that you are running DDR memory.... 'Dual Data Rate' or 'Double Data Rate'

www.google.com for how it works

so basically if effectively doubles the throughput - just multiply the clock speed by two... so yes... your PC3200 ram DOES run at 400MHz.


"CPU-Z shows me that my memory card got only 200MHz"

It's easier to say "RAM"

I'm suprised at the general lack of hardware knowledge on this forum, although I guess not everyone is the hardcore hardware modder that I once was lol

People have to learn from someplace.

If you've got pc3200 ddr, it will be running at your bus speed. If your bus speed is 200mhz, then that is what your memorys speed will be. The rating on the ram only means how high it will go before becoming unstable.

No. DDR 400 (PC3200) Ram runs at 200 MHz. However, since it is DDR, so its *effective* rate is 400 MHz. So in reality, DDR400 Ram only runs at 200 MHz, but does the same work as 400 MHz non-DDR Ram.

PC3200 (DDR 400 Ram) refers to the amount of memory bandwith of the Ram. In this case, PC3200 means your ram has a maximum bandwith of 3.2GB/s. PC2700 means your ram has a maximum bandwith of 2.7GB/s.

Yeah, but pc3200 ram is ddr400. I have never seen anything different. And I don't want to become too technical either

So, my RAM is running at 400MHz... k, thats all I wanted to know!!!
Thank u all!!! :thumbs:

 

[Ecthe|ioN]

So I learned something new today I was wondering why my RAM only displayed 200MHz as well. Spank you for clearing that up.

 

[m3ta1head]

I have regular ram that runs at 133mhz :\

no its running at 200MHz its just that the marketing people like to con you into thinking its running at 400MHz when its not! :E

(Actually its running at 200MHz + double data rate which means its fetching data on both the up and downcycle of the electrical pulse so the marketing people like to say its running at twice the speed by calling it 400MHz)

Yep! That's why when ever I talk about memory speeds I write it like PC3200 200MHz (DDR400).

Just like Intel's FSB runs at 200MHz yet is rated at 800MHz and Athlon XP 3200+ runs at 200MHz yet is rated at 400MHz.

Although the Athlon 64's HT actually runs at a true 800MHz... :O

Asus, Intel's FSB does indeed run at 200. But it's quad pumped. 4x200 = 800. So it's a true 800mhz. CPU's such as the Athlon 3200+ (Barton core) are dual pumped. 2x200=400 True 400. Barton 2500+, 2x166 = 333, etc etc. See, when you overclock, you're increasing the multiplyer, or the bus speed.

 

[Asus]

Well as I understand it, both Intel's Pentium 4 and AMD's Athlon XP use some tricks and 'twist' the bus for dual or quad pumped. Not sure how to explain it. Basicly pushing more data than normal, similar to DDR.

A quad pumped bus that runs at the 200MHz freqency with the performance of a 'single pumped' 800MHz bus.

With CPUs and serial HyperTransport links, they use a multiplyer to actually multiply the freqency based off of the base clock (200MHz).

You could have just quoted me.
