At this point in time the Gina card must run on a computer thats base clock setting for the buss speed is the standard standard setting of 66 mhz.. Some processors ( notably any Cyrex processor over 200 mhz) require the motherboards base buss speed be set at 75 mhz,or some other nonstandard value.. This will make the Gina run erratically and cause the computer to freeze...The workaround ; The customer can usually set the clock speed to 66, and then set the multiplier speed for the cpu to match the base clock..they will be sacrificing CPU and overall system speed however...It's either this, or change out the CPU for a faster unit..
