Old Intel mobo sees 200 CPU as 90

[gjwilson]

I just replaced a friends dead mobo with an almost exact replacement......an Intel AN430TX socket 7. I pulled the 200 mhz cpu and put it in the replacement board and it only sees it as a 90mhz processor. It`s supposed to automatically read the cpu so there isn`t a jumper to switch for setting the cpu speed. Do I need drivers for this old beast ? What do you think? Gary

If you know for sure that this board can support a 200mhz CPU I'd suspect it might need a newer BIOS. Also, the 90 number indicates it is running at 60mhz FSB, also lower than you need to get 200, which should be 3*66.

Usually older socket 7 boards had some jumpers on them. I have been wrong before but it seems early for jumperless motherboards back then.

It is impossible to detect the _intended_ CPU speed grade on socket 7 processors. You need to set it up right via jumpers or in the board's BIOS.

Yep, never seen an old TX board the could auto detect.

Thanks for the thoughts......I `ve been on line with Intel and they say ,Yes, that board has auto detect. The jumper for setup allows access to the BIOS but it doesn`t allow changing of the CPU speed. I`m not sure where to find a newer bios for that old of board.......might just have to absorb the cost and buy her a newer board. Haven`t flasfed a bios before and I don`t want to start on someone else`s board. Gary

Woops..or should I say whoopie.....My mistake. The mobo auto detects the "type" of processor not the processor speed. I have found both the jumper configuration for setting processor speed and the site for a bios upgrade should I get brave. Thanks again, Gary

Glad ya got it Bubba :)

I had an old Abit TX5 which was jumperless and as far as I can remember it auto detected the cpu's I put in it just fine.

No way. No socket-7 CPU has had a readout of its intended operating speed. Complete auto-detect of a socket-7 CPU is technically impossible, all a BIOS can do is detect the make and model, set a known safe voltage and fire up with the lowest known speed setting for that model - and then prompt the user to set the CPU speed correctly for what has just been put in.

I stand corrected, well sit actually but lets not quarrel about that. ;)
