This might be stupid question for some of you but im unsure about something. Should'nt my FSB be 533. My chip is the P4 3.06GHZ HT 533FSB. I have tried with HT Tech turned on and off in the BIOS but its no difference. Is there a jump setting that needs changing or something or is this how the chip comes. Type in a rush, Comp spec below thnx in advance :p

I can't reallly understand what's the problem here. Your system is already running with 533MHz FSB, as you can see from "System Bus : 534.64 MHz QDR" and also your CPU is running at the correct clock speed, "Internal Clock : 3074.19 MHz".

My thoughts, but it's been awhile since i built a computer and never used Intel before and when ppl start saying "Thats not right" i started to doubt myself. Thnx for clearing it up :)

actually 533mhz fsb is 133mhz "real" fsb

My own beast: Athlon 2700xp+ (oc: 3200xp+ with 200fsb) , Radeon 9800pro (oc: 410/370) , 512mb ddr400. SO MUCH faster than my last computer (pIII 550......)

Yes, well, but since QDR was written there, that's OK. It's just that 533Mhz is the data transfer frequency, that's all. So it's actually 133Mhz, but four bits of data every clock...

How exactly does AMD measure there fsb? There's isn't 4 per clock cycle it's two isn't it?

2. That's why AMD's 400 bus is actually 200MHz in clock cycles. And Intel has the 800 bus. And that's why Dual Channel does more for Intel than AMD.

But at first.. wasn't intel all for Rambus and AMD all for Dual channel?
Well everyone went dual channel.. wouldn't you being AMD wanna go with the faster memory due to the dual channel not being as fast for them?
Or was it all a price thing..

No, Intel was for Rambus, which WAS dual channel on the P4! Their P3 Rambus chipsets were single channel. AMD had little or nothing to do with dual channel, it was nVidia who pushed it into the AMD market.

AMD has a DDR CPU bus and the chipset use DDR SDRAM. Both are 64-bit, and synchronous, so everything is well balanced in single channel mode with no bottlenecks to RAM access by the CPU.

Intel has a Quad Data Rate bus, which carries TWICE the date transfers as Double Data Rate, hence the P4 profits from Dual Channel, which adds TWICE the bandwidth to the RAM.
