DDR2 667 only run 533

The Pentium D 805 runs on a 533mhz FSB- not 800mhz.

Sorry bud... looks like you got the wrong Pentium D.

Sorry I mistype that FSB, I know it's only 533Mhz, but is this mean that I can't run my RAMs at 667? Is there any way I can make it without replacing the CPU or mobo?

So normally RAM can't run faster than FSB? If I force my RAM faster than FSB will that be called overclock? AFAIK overclocking = increasing CPU clock.
And can you mention that "new motherboard"?
At first I was planning to buy Asus P5LD2-VM, but it was out of stock, so did Gigabyte and MSI. So I bought this Intel mobo.

I can't find neither RAM divider in my BIOS nor FSB setting, the only thing I can adjust is the RAM speed (400, 533, 667) and RAM timing. But everytime I set to 667 it won't boot and I get 3x beeps. Is this mean Intel D945GNTL is not overclock-able?

Just overclock that 805 and it will take advantage of that 667 RAM. That actually gives you some serious headroom.

I think you got all the freqeuncies mixed up.

1st and foremost, pentium 4's use a quad bus so, 800MHz / 4 = 200 MHz. so 200 MHz is the actual bus speed.

2nd DDR memory frequencies are actually multiplied by 2, since (i forgot the actual explanation) it has something to do with 2 things being done in 1 clock cycle at a time. Thus DDR 266MHz actually runs at 133, 333 runs at 166, 400 runs at 200MHz. This is also the case with DDR2, a DDR2 533MHz ram runs at 266MHz (in reality).

You don't divide the ram frequency by 4 and then multiply by 4. You only overclock by raising the FSB, NOT THE RAM SPEED. In synchronous mode, if you raise the FSB, the RAM speed also goes up! In asynchronous mode, wherein you set the two independently, i know that you can't raise the mem speed higher than the FSB. That's why it won't boot, it simply can't be done.


ON THE BIGGER AND THE ONLY ACTUAL IMPORTANT PART OF THIS POST:
The 945GNTL is a board that you can't OC, period. I also have the board and it has no option of setting the FSB, so any OC dreams are crushed with this board. The Mem speed settings are only left open because if you have say a 800MHz FSB CPU, and say you want lower mem latencies, you could throttle down the 667 to 533 and set the proper latencies. YOU CANT up the thing if you're using a proc with a 533 FSB.


Though i do hope that you're able to read this.

amnotanoobie replaced the real facts

but yeah its possible to run the ram higher than the fsb. If the possibily of choosing 667 is there, its because it applies a ratio cpu:ram of 3:5 when you get a cpu that runs at fsb200.

if you couldnt run ram faster than the fsb, the option wouldnt be there.

now I dont know what the mobo does when a cpu with fsb133 is installed. And I dont understand why it wont boot
