Defect in graphic card?
When I restart my computer (when it has been turned on a while), my
Point-of-View TI-4280 draws some wrong characters, at random locations. It happens only when I am in text-mode. In the DOS prompt in Windows, there are some columns which are mostly blank. On the boot screen, there are random characters instead of spaces. The problem began first 4 months after I bought my graphic card. I exchanged it then, and got another card of same model. It worked fine for 2 months, and now the second card has the same problem. Does my motherboard (Asus P4G8X) provide a voltage which is too high, is it an error that can be fixed with software-updates, and what can the problem be due to? I have a Thermal Take Xaser II cabinet (5 fans) with an average temperature at 26°c (78.8°F), so I don't think it has been superheated. Hope you can help me. |

Boot to safemode/Device Mangler and remove ALL entries for the display adaptor and re-booot and let windows re-install it and look for updated drivers.

From the pictures I just saw on the 'net it looks to be a cheaply constructed card and so the caps would be more likely to fail, sooner rather than later. You might have POV replace it under warranty again but if they keep sending you the "same" model new card with marginal capacitors the only long-term solution might be replacing the capacitors or buy a different card. You might express your concern with POV and see if they'd replace it with something else. The following link shows those caps I'd replace (assuming your card is the same as pictured or similar enough) and the replacement order from more to less likely to need replaced (which is only speculation based on observations of other TI4200 cards). http://69.36.189.159/usr_1034/pov_Ti-4280_caps.jpg Dave |

At 66MHz bus it's fine but at 100 it has artifacts all over the BIOS screens but is absolutely fine in Windows. (This is running a celly 600@900). I don't understand it as it's my understanding that the AGP bus is back in spec at 100MHz. (MS6163 Pro). -- ~misfit~ --- Outgoing mail is certified Virus Free.

I suspect the problem you're running into is that some boards, once they post at a certain FSB/AGP ratio, can raise the FSB but the ratio for the AGP remains the same. So, to get the ratio correct the system must initially POST at the higher FSB rate. I am not sure that it applies to that particular board but assuming the CPU is happy @ 900MHz it seems the likely problem. Different ways to get the higher FSB before POSTing might include: - FSB jumper on the board - Slotket jumper - Slip a 2mm long piece of ribbon cable insulation over the CPU BSEL0 pin and slightly ream-out the corresponding socket hole so it fits. On this pic it's the pin to the right of the one featured: http://69.36.189.159/usr_1034/s370_bsel1_133FSB.gif - Break off same BSEL0 pin Dave |

I don't understand it as it's my understanding that the AGP bus is back in spec at 100MHz. (MS6163 Pro). What method did you use to set the FSB? Option in the BIOS. It goes from 66MHz to about 155. It was my understanding that at 100 it put the AGP back in sync. I suspect the problem you're running into is that some boards, once they post at a certain FSB/AGP ratio, can raise the FSB but the ratio for the AGP remains the same. So, to get the ratio correct the system must initially POST at the higher FSB rate. I am not sure that it applies to that particular board but assuming the CPU is happy @ 900MHz it seems the likely problem. Yep, the CPU is happy. Prime95 runs for 24 hours with no errors and the HS is hardly warm to the touch. (I used AS3) Different ways to get the higher FSB before POSTing might include: - FSB jumper on the board - Slotket jumper Niether avialable. - Slip a 2mm long piece of ribbon cable insulation over the CPU BSEL0 pin and slightly ream-out the corresponding socket hole so it fits.

It doesn't matter if the board/chipset natively supports the FSB speed, I've had to do it several times for o'c Tualatins to 133 too, was the initial topic prompting the marking on above linked pic. If the CPU can run 900MHz without any voltage increase, I'd probably break the pin off, since the CPU could still be moved to another board someday and would work at 900Mhz, or use the insulation if it needs voltage increase.

OK, thanks. Food for thought. I'm toying with the idea of trying a higher FSB. I haven't yet as I was just pleased to get 900 out of it. I've since heard of others getting over 1GHz out of these CPUs. Did I mention it's in a slocket? -- ~misfit~ --- Outgoing mail is certified Virus Free.

I still have a Celery 600 "c" core around here somewhere, will do 1.2GHz at 1.85V, though it was just barely instable at that speed in two different slotkets, only stayed stable @ 1.2 on a S370 board. Mine is atypical though, most would only hit slightly under 1.2Ghz until the "d" core, which is a shame since hitting 133FSB (& 133 Mem) really helps a Celery, though if your board has 1/4 PCI divider option at 124 FSB, that might be another good option. These weren't BX boards though, you may need a decent northbridge 'sink to approach 133FSB. Dave |

It has a slot and a socket, haven't had time to play with it. I don't think it's a BX, it has Intel......... 810 on the northbridge. And no 'sink. My BX boards have sinks. I may play, dunno yet. I'll research this board later (got to go out) but, as it's going well now, I'm loathe to try it in another board. It's my fileserver/gateway machine so it really doesn't have to be fast. I just use it for crunching SETI WUs on too. (+or- 10 hrs per at the moment using GUI) -- ~misfit~ --- Outgoing mail is certified Virus Free.
