Locked Intels

Website · by **skier** » Sat Jul 21, 2007 11:48 am

I have a P4 3.0GHz in a dimension 4700, it says it has a fsb of 800MHz in the BIOS, but the RAM is only 400MHz(so 200 in reality) are locked Chips always at the standardized FSB regardless of the speed of the Memory, and does the Ratio automatically adjust itself(from DDR2 400MHz to 533MHz)?

any help is appreciated(i dont really know much about locked chips)

all chips are locked whether it be intel or AMD. You have no control over the multiplier, expect for certain high end Intel and AMD Chips. Ram is dual pumped (so 200X2 = 400 FSB which is the rating of your memory) and Intels are quad pumped (so 4 x 200 which is 800 which is the FSB of your chip). Yes the board will adjust the multiplier so that it achieves the needed FSB for the chip to run at its full speed. It uses multipliers to do that. If you have 533mhz ram it will run a multiplier of 3:5. 800 would be 1:1, 400 would be 2:1.

oh.. thanks again for awesome help dicecca :prayer:

i had no idea it was quad pumped, i just though CPUz was reading wrong when it said 200MHz FSB

It's not wrong, that is the ACTUAL FREQUENCY.

Distributed Processing hardware designs are not rated by the real operating frequency but effective bandwidth throughput being bandwidth based.

For example... in this case the bandwidth throughput performance equated to that of 400MHz Symmetric Processing memory designs, or PC3200 = 3.2 GB/s throughput with actual memory operating frequency = 200MHz.

The terminologies are simplified for 20+ years Intel's hardware experts trained-by and stuck-with Symmetric Processing hardware. Not capable and/or not flexible enough for comprehending/using Distributed Processing terminologies.
