John-Mark Gurney stands accused of saying: > right now I'm running a i486dx33 at 40mhz... and running 70ns ram at 0w/s > if I remeber right... I believe I had to turn of FAST page mode dram > though... but I do have a question... I can get a Cyrix (yes I know.. > they suck) 80dx2... could I run the chip at 80mhz (my motherboard > supports it) but not double it? would there be problems with my IDE You don't understand. You run a DX2/80 at 40MHz, and it doubles internally. > vlbus controller? would my isa bus break? from what I have heard about It would look like a DX/40 to your motherboard. You would most likely have to set the >33MHz VLB jumper, which would then run your VLB at 20MHz. > the motherboard doing to slow down of the chip on doubled and tripled > chips that the cpu is actually rated at the fast mhz but I don't have the > technical background to know... thanks for the help...
