Each time I try to overclock on 2D Core Clock to max on DVI it freezes! My graphics card has the DVI input and I have gotten the DVI adapter. I ve seted it all up and still it wont work! Am overclocking on 600MHz... Can anyone tell me why and how can I fix this? Thanks in ahead!

Windows XP SP2
1280 Mbytes of RAM
AM2 Live! AFG6-LIVE (or something like that)
AMD2 Athlon 64 3000+

My specs are above!

Summary and practical steps to diagnose the freeze when the card's 2D/idle core clock is forced high while using the DVI output. As noted by this manifests as a hard freeze; as pointed out, heat and instability are common when clocks are pushed far beyond stock. The digital output itself is unlikely to create the freeze — the problem is almost always an overclock/power/driver or adapter issue.

Recommended checklist (follow each step and test before moving to the next):

  • Restore stock clocks and confirm a clean, stable baseline boot and desktop. Monitor for artifacting or instability with a short stress run.
  • Raise core clock in small steps (single-digit to low-double-digit MHz), test each step under load for several minutes. Do not set the 2D/idle clock equal to the 3D/load clock unless voltage and stability are proven.
  • Monitor temperatures, core voltage and GPU activity while testing. Use a hardware monitor to watch spikes and thermal throttling.
  • If the freeze occurs only when the DVI connection is used, confirm the adapter/cable type (passive DVI-I vs digital-only DVI-D or active converters) and try a different cable or output to rule out a faulty adapter or EDID/power handshake problem.
  • Check PSU capability and rails; an older or marginal PSU can collapse under increased GPU draw. Also verify heatsink contact and VRM cooling.
  • Try a clean driver install and one well-known stable driver revision. If overclock tools allow, raise core voltage slowly only after stability fails at lower voltages — this carries risk and can shorten component life.

If the card still freezes after conservative, incremental testing, accept a lower stable overclock or consider hardware repair/replace. Useful utilities: MSI Afterburner for controlled overclocking, GPU-Z to monitor clocks/voltages, and FurMark for stress testing. For DVI signal details see Digital Visual Interface.

overclocking anything like a gpu or memory or a cpu is bound to make it unstable at some point. have you checked the heat or run any stability tests?

what is the standard core clock of the gpu without an overclock, is it 600 mhz or is that what you were overclocking to?

My default Core Clock speed is 350MHz, temperature is 41C (as always). The problem is when i try to go maximum (600MHz) the computer freezes then I have to shut it down manually. That never happened before. It just becomes unstable. I tried rolling back drivers, nothing! Before that I ve tried updating them... and now this issue appears in VGA mode too!

Yeah overclocking from 350 to 600 core doesn't seem that safe. You may have seen reviews on the net that say that card can be overclocked like crazy but you could really damage it going that high.
