mick_the_prick Posted May 2, 2005 Posted May 2, 2005 Just for fun. I have an old 486sx 25. the mobo is a via486-vc. the cpu is soldered to the board and it has one cpu upgrade socket and i think one overdrive socket. it has jumper settings for 486SX, 487?? and 486DX/2. If i get a DX/2 cpu and stick it in it should work, but does anybody know anything about the other socket? If it is an overdrive socket, do i need a 486DX cpu or do i just need an overdrive socket?

bigred Posted May 2, 2005 Posted May 2, 2005 it's not overdrive socket. it's for a math co-processor (x87 series). if you had a DX series 486 it would have the co processor as part of it. Share this post Link to post Share on other sites More sharing options...
mick_the_prick Posted May 3, 2005 Posted May 3, 2005 so if i just put a DX cpu in it thats all i have to do? Share this post Link to post Share on other sites More sharing options...
Guest FxXP Posted May 3, 2005 Posted May 3, 2005 so if i just put a DX cpu in it thats all i have to do? 472077[/snapback] You can't. You mentioned that the CPU was soldered to the board. The math-co upgrade is the only one you can do to the board. However, check to see if the socket is an LIF (low-insertion force). If so, you can pry the processor out and put in a DX-2. The DX-2 is double-clocked to DX. Share this post Link to post Share on other sites More sharing options...
mick_the_prick Posted May 4, 2005 Posted May 4, 2005 Or i could just use the 486 motherboard as a frisbie and get a $10 pentium 1 mobo and cpu to play with. Thanks for your help. Share this post Link to post Share on other sites More sharing options...

tazwegion Posted May 8, 2005 Posted May 8, 2005 (edited) Hmmmm... seems like yesterday Are you sure the 486 is 'soldered' on, and not inserted into an earlier style ZIF socket? (as in the picture below) For reference, the following picture is an actual DX2 OverDrive PR66 Oh yeah, FxXP didn't the P75's have some mathmatical error/issue? <_< Edited May 8, 2005 by tazwegion Share this post Link to post Share on other sites More sharing options...
bigred Posted May 8, 2005 Posted May 8, 2005 no the P75 was the first 5th generation x86 that didn't have that problem. the 60 and 66mhz version did however. Share this post Link to post Share on other sites More sharing options...
