G400 overclocking
This may be a strange time to bring up overclocking the G400, it has been discussed before, but not recently as far as I can recall.
I've bought 2 replacement cards for my G400, a Powercolor Evil Kyro and a Radeon SDR.
The Kyro's 2D was too poor compared to the G400, and I returned the Radeon SDR due to the G550 rumours.
As I'm back with the G400 I'm looking to maximize it's performance.
I'm extremely surpriced by the overclockability of the core, mine's runnning at 185 MHz (a 48% overclock) with standard cooling, and I'm sure it'll go faster especially if I add a fan.
The memory is my bottleneck, it's 6ns and can run at 180 MHz. Today I mounted some ramsinks which lets me run at 185 MHz (maybe a bit higher, but 190 was a no-go).
I'll add a 80 mm fan to blow air over the core and ram sinks, and hopefully it'll go a bit faster still.
How far have you people been able to clock the G400 core ? If mine is any indication of average overclockability it really surprices me that Matrox hasn't introduced a G400 Ultra (or whatever they would call it). With core/mem running at 180/240 it could have followed the competiton for a while longer.
