P!! board acting weird with PIII CPU
Are all Pentium II motherboards compatible with Pentium III CPU's?
I have a computer that has a Pentium II 266 Mhz CPU, and it works fine. I tried to install a PIII 700mhz CPU. It boots up (at least to dos, since I just plugged in a temporary harddrive with only dos on it.). Anyhow, it boots up, but I get error beeps, and it says on the CMOS screen "? 500MHZ" (With the question mark, just like I typed it. The MotherB is a Premio 212B. The CPU is an Intel 700mhz. PIII. Does this mean the MB just cant handle this CPU or what? I transplanted an identical CPU into another computer that was a 300mhz and it worked fine. I also tried to change the CMOS, but its kind of oddly configured, It gives me the oprions for 222 or 333 in several places. (having to do with the CPU). I am not familiar with that type of CMOS. I tried it both ways, I also let it use it's default. Either way, I get this oddball ? 500mhz..... Anyone have any idea whats going on? George |

George When putting a Pentium III CPU into a Pentium II Mobo, make sure you wet the pins real good before inserting the CPU. Distilled water is the best, but spit will do in a clinch. Keep trying- you'll get it to work eventually. |

The 212b uses a 440LX chipset. That only supports a 66 MHz FSB (front side bus). The PIII 700 has a 100 MHz FSB: if it ran at all, I'd expect 467 MHz. I doubt that the board will run Coppermine CPUs at all. It's just as well. Antique computers (1997) should be kept in their original configuration. ;-) Address scarmbled.

But if that is true, would the BIOS be able to run long enough to print "? 500MHZ" on the monitor ? That is what I find puzzling. If it was just incompatible (socket not prepared for Coppermine), it should be a black screen with no writing. Paul |

If it was just incompatible (socket not prepared for Coppermine), it should be a black screen with no writing. Paul There are a couple of issues involved. Assuming that the multiplier is locked at a value of 7 for the Coppermine PIII 700 MHZ CPU, then it should be reading 460 MHz on the old PII motherboard. It is not since the PIII is also running with a Vcore that is approx. 0.4 V higher than spec. It is going to take more than a bios update to run this PIII Coppermine; the voltage controller must be able to run at approx. 1.6 to 1.7 V. If the PIII CPU has not already been fried, it will be shortly at 2.0 to 2.1 V. |

If the PIII CPU has not already been fried, it will be shortly at 2.0 to 2.1 V. Since I am not all that familiar with what CPUs work with what mobo, I'm just going to find another mobo. I already know that I have to avoid the PII boards, and I'm guessing the new mobos made for the P4 is probably too new. Besides I need to keep costs down so I will probably look at a used computer store (recycler). Or, if I want to take a big risk, Ebay. the CPU is an Intel PIII 700/256/100/165V S1 90240298-0026. What mobos will work with this, or I should say what numbers or terms do I need to look for? What does Coppermine mean? On the CPU, the 700 is MHZ, but what does the 256 and 100 mean? This multiplier of 66 or 100, what does that mean? Is that why many computers are x66 (like 266mhz). I always wondered why they made them such an odd number. I have been looking on Ebay (just to see what to look for), and Asus seems like a popular brand. Any model numbers I should look for in that brand, or is there another better brand? I want a board with lots of card slots, and at least 3 memory slots, plus it must have an AGPslot for video card. I dont want a card with built in video, sound dont matter. USB 2 is preferred but I do have an extra USB 2 card. All help appreciated. George By the way, that CPU did not say 460, it said 500 ??? The computer stayed booted for a half hour in dos mode. Either way, I removed it and put back the orignal 266 CPU. The computer still works with the 266. and that 266 is actually faster than this computer I am using now, which is a 500mhz. I know this mobo has a built in video card and it's a POS. The mobo dont have an AGP slot. |
