Underclocked

[shadowbreaker513]

I was looking on the ATi website and it said the 9800 Pro's memory is clocked at 680Mhz. I looked at the speeds on mine, and it is clocked at about 340Mhz. Is this something to be worried about? Or for some reason is it picked up the clock speed at half of the stated?

I believe you are looking at the core speed instead of the memory speed. The ATI Radeon 9800 Pro 128MB 256-bit version has a memory speed of 680Mhz and Core speed of 380Mhz. In any case, the underclocking if any, is not as severe.

You're probably seeing the actual memory speed, 340Mhz. With the effective (DDR) speed being 680Mhz.

Somehow, I neglected to think of that when I thought DDR RAM...scrap my previous post.

Ok. All the things I looked at said that so I thought I might as well ask. Mabye that's also the same situation with my fsb.............

The FSB of your Processor, yes. It depends on your processor, but Intel Pentium 4 processor have a quad pumped structure. So what is advertised as a 200Mhz FSB would be 800FSB. Same with AMD but less. What is advertised as their 266Mhz FSB would be 133Mhz FSB.

So having mine set as 200Mhz means it's running at 400Mhz which is right for processor correct?

If you're talking about the build in your signature, technically, no although theoretically, your processor takes the 400FSB as its memory speed.

Sorry, I'm confused.

in the bios, you should set your RAM frequency to 400, your FSB should be 200. the RAM's actual frequency would be 200 but because of DDR technology, it would run at 400.

Look at his signature Yuanji. I'm not too familiar with how the Athlon 64 handles the FSB system, which is "integrated into the chip", so I explained as far as I could...

i think in the athlon 64s, HTT acts like the FSB. it's supposed to be overclocked similarly to the Intel way of Ocing but i do know that athlon 64s are 400mhz FSB chips.
