Will a D845EBG2 motherboard support a RH80532GC017512 CPU?

Well, i'm not even sure if the board or the CPU works, so it couldn't hurt to give it a shot; however, if one or both did and the board gives it too much voltage, that wouldn't be good. The CPU runs from 1.2-1.3V. I'm not sure what the board runs at or if it can automagically detect and adjust for CPU voltage. I know the stepping on this CPU is fixed at 14x and at a quad pumped 100MHz bus it clocks at 1.4GHz. The board supports a 400/533MHz bus. Will this work or will the CPU be toast?

I had a mobile P4 chip running in an 845PE mobo for a while. The mobile P4 chips require BIOS and chipset support for SpeedStep, in order to run at full multiplier speed. Otherwise, they clock down to 12x. Voltage-wise, I don't know what that board ran the chip at, but it can take desktop voltage levels I'm pretty sure. So you should likely be able to get it to work, at 12x 100 = 1.2Ghz, or perhaps higher if the mobo supports a higher FSB speed. My board supposedly supported 200Mhz, but had issues with the memory at that speed, so it wouldn't boot. Otherwise I could have had it at 2.4Ghz, which seems within the capability of a 2.0Ghz Mobile P4 cpu.

Will they blend?

We'll find out once i receive that DIMM someone promised me a while back.
