i have played about with my memmory timings. after what u say i'v had a look at my bios setting and info. they are as follows.
cpu fsb 133 x 18 @ 2.4 . clock open, multiplier is locked.
memmory is set to auto. the chip is fsb 200 but the bios auto set it at 166
that seems to be the lowest my bios will set the ram. it has the option of 166 or 200 or auto.
all other timings are on auto atm but i have played around with: CAS trcd and trp settings with no visible success only performance loss
i have another dimm which is a 166 chip. not in my system at the mo as i was told not to mix different dimms.
prior to installing my graphics card i had both dimms installed and running without a problem as far as i can remember.
i'm beggining to think that this card is to new for my m/b as the card has a hardware clocked memmory core @740 mhz and my sys mem 166 and cpu 133
i think the hardware o/c might be preventing the card from reducing its speed to come inline with the rest of my hardware.
i tried reducing the clock with software to no avail just incredibly slow refresh on everything. in game and desktop windows. looked like safe mode with no drivers.
i was thinking of increasing my cpu clock to 166 but i figured i might burn it out.
cpu temp at the mo is 41 deg so i think i got a little bit of o/c play
i'v only got a cheep fan and heat sink and i think that clocking my chip from 2.4 to 3 gig to sync the fsb might be too much for the heatsink to handle and probably the chip too.
spose it time to buy some new hardware.
