Running Athlon XP with DIMM memory and performance drop...

[vigi_lante]

Hi,

I want to use a processor like Athlon XP 2100+ with my motherboard. This motherboard support 266MHz of Front Side Bus DDR transfer. Athlon XP also runs at 266MHz. But this mobo only have DIMM slots of ram memory (running at 133MHz).

So, I think that I would have a drop in performance, right ? But this drop would affect tasks like processing video too (or playing emulators) ?

Thanks.

Is it not DDR SDRAM? All socket A motherboards that I know of that support PC133 also have support for PC2100.

if DDR: 266Mhz
if SDR: 133MHz

No. It only support PC133

Take a look...

My opinion is there would be a drop in performance. When I bought my Athlon 2100+ it was said that a 266MHz FSB and PC2100 RAM were closely matched. (somthig like the CPU could proccess about as much data/second as the FSB/RAM could constantly deliver to the CPU.) I guess that means slower FSB/RAM would not be able to supply the CPU with enough data/second to constantly keep it busy and a slower CPU wouldn't be able to keep the FSB/RAM constantly busy.

Video encoding is a major FSB/RAM hog. So PC133 is going to hurt that more then alot of other applications.
