How people get 150+ FSB ?.... what about the memory?

I saw someones PC running @ 183FSB is that possible ?!?!?
Wouln't the RAM just DIE
Oh ... and the PCI/AGP clock ... will CRAZY wouldn't it?

Assuming the PCI = 183/4 = 45.75mhz
and the AGP = 183*0.6666 = 121.99Mhz

Bump

I hear they use custom clock generators or something like that.

They run at 183mhz all the time?:Q I wanna know about this too.

A lot of people custom modify their mb to re-adjust the pci/agp/ram bus's......soldering resisters and such on the mb(kinda advanced)

Some people dip their whole mb into a bath tub of mobil 1 synthetic.....it's non-conductive so nothing will fry

there's always liquid nitrogen

Actually-

All of my PCI devices are stable up to clock speeds that high- and the GF2's are supposedly stable up to 100-110 MHz AGP, at least. You can pull all sorts of fun tricks to get your AGP cards to behave going that fast.

You can also buy RAM that's certified to run at 175 MHz at wonderful reputable stores (BS! *cough cough*) like OCZ, drop your memory timing, and go a little higher. I've never tried going that high, but I've gotten pretty close, so I don't see why it wouldn't be possible.

Check my system specs if you want to see what kind of PCI goodies will go that high and not fry.

Whoops-

Forgot to add that the newer boards have AGP dividers of 1/2. So running at 183 bus would put you at 91.5 MHz, which the GF2's can do.

I was running 138 bus on an old P3-450 with an Abit BX6-2, and it was pretty happy. It was a BX chipset, so the AGP divider was 2/3.

138 * 2/3 = 92 MHz AGP bus
138 * 1/3 = 46 MHz PCI bus

My video card at the time was a Guillemot Xentor32 (TNT2 Ultra). I also had a Diamond Viper550 (TNT) that was happy at the AGP bus speed.

The RAM that I was using was 128 MB of good old Crucial Technologies Micron RAM, the PC100 -8E version. You'd be surprised at how high that RAM can go..

I would have tried for a higher bus speed, but the CPU would not go any higher. My next step was 143 MHz, I think.. and that was just too big of a jump for the old P3 core.

Damn. Forgot something else... that was all air-cooled. No fancy-schmancy stuff going on with that system setup.
