I think this mobo will support down to 1.6ghz (or 1.4). I can't see blowing ~$150+ on a chip when I only payed $17 for the mobo! And I bought it through the mail from weirdstuff ~8 months ago, so therefore if it don't work (was new though) I'll be at less of a loss.
Anyone got any pictures of sick case mods by the way?

umm as far as FSB speed, 433 or 500 mhz (from memory). Or does that not make a lick of sense?

USSEnterprise may be able to help you with the CPU, but as far as RAM, does the board require RDRAM, SDRAM, or DDR RAM? RDRAM has two notches in the middle about .5" apart; SDRAM, as I would imagine you know, has 3 notches; and DDR has 1 around the middle. As soon as you post which one, we can help.
:eek:

SD RAM only has 2 notches. RDRAM rulz.....

RDRAM is way too expensive, and I'm keeping my system for the MAME cabinet, tgunner. Sorry

Yeah, I kow its uber expensive, but Its my favorite.....
(No I don't know why, it just is......)

MAME CABINET!? Converted or custom built!?

By the way, isn't RDRAM like 3X faster than SDRAM because it doesn't have to keep recharging micro capasitors or something like that? (I don't know much about memory)

RDRAM runs at 800MHz and up. Its a lot faster than SD and DDR. The highest level of RDRAM is 1GHz. Thats why I don't see what all the fuss about DDR2 is. RDRAM was at 1GHz long before it was.....

I don't see the point. wouldn't the speed of the RAM be limited to the CPU's bus speed?

Someone else wanna explain this one? Its getting late in my TimeZone......

Oh, and no, its not.....

Those PDF's are the who what when where and why of RDRAM. Check em out.....

The speed of the RAM is not limited by the bus speed (FSB) of the computer. The RAM uses it's own local (processor direct) bus (a back-end bus) to the CPU. Does that sound about right? (It's late here too)...

custom built. The cabinet is completed. I just need the PC, control panel (I have all control panel parts), and a 19" LCD

Sorry, I had just gotten up, and was picturing in my head, the three sections of pins...

Yes, but I said "Limited". Systems usually crash if the bus speed of the CPU is higher than the bus speed of the memory.

tgunner, ah It happens. I have come up with some strange stuff too...

USS Enterprise, Thst sounds like one wicked machines you've got going.

Atari2600a

indeed that would happen, but why would the FSB be faster than the memory clock?

And just to watch your mind shift gears with out the clutch, the Rambus Corporation also makes XDR, which has a memory clock speed of 3.2 Ghz. O_o Thats got a peak bandwidth of 16 GB per second. Now thats high speed.......

Say you have a PIII 866 MHz with a 133 MHz FSB, and you put PC100 RAM into the motherboard...

As far as a CPU for Chris2005, check eBay, I just looked, and you will be able to find a used with warranty, P4 1.8 GHz chip for under $40 including shipping.

LOLOLOLOL The Memory bus and FSB can run at different speeds in both directions. I was tired, I was lucky to hit the keyboard at that point. (IBM Model M, so its a little hard to miss....) I'm not sure how I came up with that one......
