The GeForce FX series sometimes mis-reports RAM speed, as for some reason the program reports/doesn't report the DDR'd rate.
What's your method in detecting the GFX's cclk and mclk? Is it by driver’s "cool bits" features or by third party applications?
they've been nothing but rock solid on a GeForce 4Ti 4200 OC'd to almost 4600 speeds.
Note that the Geforce 5900 (PV) normal editions can be softmod’ed to 5900U or 5950U via BIOS reflash e.g. Albatron’s heatsink is the same across 59xx series.
FX OC’ing may have issues with FX bottom end cards e.g. FX 5200. FX 5600 can be soft'moded to FX 5700 (use google for success rates and comments) .
The success of OC can be influence by PS, type of motherboard(e.g. A7N8X Dlx Rev 1.04), gfx memory timings, build quality of Gfx card i.e. if I O’C my Geforce TI 4200 to 4400 level it will destabilize the related voltages lines (via ASUS Probe). It still works at 4400 level but it may stress motherboard's related power regulators. Leadtek has stated that there’s a minor difference between Leadtek 4400 and Leadtek 4200 in terms stabilization circuits. PS; GA-7N400Pro2 can handle it due to a separate P4 style power lines.
