Basic overclocking question
By the time you damaged your card with overclocking
you really don't wanna use it anymore. "MattB" matt.baranski @ bigpond.com schreef in bericht ... Hi all, I picked up an Albatron Ti4200 128mb card today and want to overclock it a bit. I tweaked the driver level clock frequencies to 270mhz core and 533mhz memory and the card seems perfectly stable under D3D games with no artifacts. My question is, will this cause the card harm in the long term (stock heatsink/fan)? I plan to hang onto this card for at least a year, does excess overclocking show itself as system instability or is it likely to just die unexpectedly after being overclocked for a period of time? I guess basically I want to know how much overclocking will reduce the life of the card. Cheers, Matt |

I can o/c my sparkle to 270/540 with no problems have for the last 9 months.
If i go higher on the memory, the memory chips get too hot and i get artifacts onscreen. The card will do about 275/550 stable but gets too hot for my liking and i cant be bothered with extra cooling, not worth the trouble or expense for the speed increase i wreckon. For some wierd reason i like too keep the memory twice the speed of gpu (paranoid maybe). i dont get much improvement with gpu increase only. Just for reference i get about 11000 in 3dmark 2001 at default settings and 13000 when overclocked to 270/540 Unless theres a fault with your card i wouldnt expect its life expectancy to shorten by any noticeable amount and unless u get some extreme heat issue which i wouldnt expect at the setting u r running at. Excess overclocking of the memory usually shows up as artifacts on the screen like white dots at random, missing textures or dark rectangle/triangle objects flashing on the screen. Excess cpu overclocking for me shows up as games crashing and computer locking up or games dropping out and going back to the desktop torr "MattB" matt.baranski @ bigpond.com wrote in message ...

I have been running at 266/566 for some time now (1 year) on my Ti4200, and if anything, it's even more overclockable now. /M |

What is the best overclocking program to use? I have a PNY Ti4200 and would
like to speed it up. Can you guys recommend one for a novice? Thanks! "Martin Eriksson" wrote in message ... "MattB" matt.baranski @ bigpond.com wrote in message ...

Estimated life is ~ divided by 2 for every 10 degreesC above 80 degreesC CHIP-temperature. Damage is irreversible. You may or may not see artifacts before irreversible damage. Silicon slows down significantly with increasing heat, so it may slow enough to see artifacts before transistors or silicon-vias go POP or it may not............ Just make sure that you have enough reserve cash in the bank for a replacement card. The video card memory is far less likely to go POP unless it is has poor local cooling or is grossly overclocked. Or shares the same physical heat-sink as the GPU plus a poor heat-sink design allowing low thermal resistance between GPU and memory. FYI:- Unlike the CPU chip-temp monitoring on modern motherboards, most video cards have no GPU chip- temperature monitors, although the design and thermal-stress rules are exactly the same as for CPUs. The latest video cards ATi9700, 9800, FX5800, FX5900 cost more than most CPUs and disspate as much power as a 2.6GHz P4. Out of these only the FX5900 has built-in user-accessible chip-temperature monitoring. John Lewis |

And the DATA to back this statement up ? You may be confusing the very poor cooling solution on the FX5800 with the actual chip temperature of the GPU. Neither nVidia NOR Ati publicly publish any diissipation figures for their GPUs. The process, transistor-count and clock-speed are the key determining issues. There is no silver bullet. The FX5900 15% higher transistor count and sligfhtly-higher clock speed, but 0.13u process (and lower core Vdd ) instead of 0.15u on the 9800 results in about the same power-dissipation. Come back when you have real data to back up your argument. Go install a temp-monitor on the 9800 GPU. You may get a very interesting surprise/shock......... As it is you may be blowing hot-air.............. John Lewis |
