Overclocking AGP freq. to 75MHz ?

[Joscht]

Hi

Does anybody if it's good or bad to overclock the AGP frequency to 75MHz?

Of course, I've used my G200 and my G400 at both 75 and 83 MHz FSB at 1/1 CPU-to-AGP-ratio in AGP2x mode. There is no noticeable overheating or something. If you are planning to overclock your card too, you might want to install a fan on your favorite videocard

Thanks Nautilus !

You know, I first had this problem with crashes during 3d games...
Now it's gone, since I've overcloaked my AGP freq. to 75MHz.

You can still use G400 to AGP 93.33MHz (At FSB 140MHz) without any problem. But please don't force to AGP2X.

Currently I run my P3-450 at 630MHz using Asus P3B-F and a G400MAX.

I run my G400 at 75mhz fsb. I can run it at 83 as well but my hard drive has a hissy fit and I loose all my data. I get weird dir names and lots o' corruption. But the processor and everything else is fine. My G200 ran that way for over a year no prob.

I've found an article on www.overclockers.com about a dude overclocking a celery to 680 Mhz or something like that... It was 155 Mhz FSB giving a 103 Mhz AGP bus frequency... Needles to say he had a G400 in his rig and was shocked more by the result his card worked on that speed than getting a Celery at nearly 700 Mhz with water cooled peltier cooler...

I've run my G200 on 100 Mhz but was losing textures randomly in 3D games... Reverted to 95 FSB, and everything worked fine. But since it's a slow card rising it's bus doesn't help much so it... worked on 66 Mhz happily ever after...

I thought it was the experience of most G400 owners that the cards run at 100Mhz AGP speed, in 2X AGP mode, without problems. What a fine piece of hardware--thank you Matrox!

My vanilla G400 runs fine at 100+2X, even at overclocked (170/190) speeds.
