245 MHz Memory clock MAX with PStrip

[chuck]

So let's see.
The card runs @ 20% above rated clock speed
on a buss thats 30% above rated clock speed
and the whole mess stays stable!
You'd think these guys had designed hardware somewhere before.

For those of you getting a G400 32MB Dual Head.. Check your memory speed and also check if there's a white fan power plug on your Matrox board. If you have a white fan power plug and your memory is 5ns memory, you are a lucky bastard..

Those G400 cards are basicly the Max boards but they fail the Max test so Matrox release it as the regular G400 instead of G400 Max. Those cards run at the 360MHz memory and they were clocked at 144/192. If you install the 5.13 drive and look at it in the propertey section, it will tell you it's a G400 Max but technically it isn't. It comes with the regular heatsink. I have one of those boards and I was able to OC it to 165/220 easily. I haven't push it to the max yet. I am getting and fan heatsink and gonna push it to the limit. I will keep you guys posted with the result. But don't go out there buy a G400 and expect it will run at the same speed cause result for each card might vary..

Good luck

Are you lot serious - are these speeds REAL?

It's amazing...

I'm guessing most of you will be CPU bound in the extreme... has anybosy with a beefy OC'd PIII (600+) done any tests with 3DMark or anything?

WOW

and again...

WOW.

Hi there

Is there any overclocking utility (or will there be any) that allow to change the core/memory multipliers? Like G200clk did for the g200 (it doesn´t work with the G400).

I can push my vanilla G400 retail 32Mb(6ns) to 153/204, and then that coloured dots and lines appear. Memory, isn´t it? But it NEVER locked up, so I think the core is willing for more. I would like to test it at 166/166 or something like that. Probably it would perform lower than it does at 150/200, but hey...

Maybe a new version of G4set? Where´s gbm?

Cool!

Running mine @ 145/194

MGATweak will allow you to change the core/memory multipliers

No kidding huh? You mean you can run at 175/175 or even 200/200 Wow!

[Brian R.]

I don't know what's possible. I don't have enough knowledge about these things to risk a $250 video card. Powerstrip is simple enough for me to feel secure.

Brian R. I think I lost something. What is MGATweak and when will it be released?

And about "risking" the videocard, maybe at long term, but I simply don´t believe you could just fry it overclocking it. It will simple crash and you have to reboot. Maybe at a long term, it will not last so many years as it was intended to (10?15?) but 10 years from now I am sure you will not want to be using a G400...

And sometimes simplicity doesn´t equal to safety. Remember the first powerstrip versions? They looked harmless, but some did report bios corruptions...

I know Mag, it's still early, and this was bound to happen... someone confusing G400Tweak with MGATweak.

[Scytale]

Hey Phil, I always feel CPU limited. Since you seem to care, consider it...donation time

Seriously I think the first statement of the G400 being CPU limited has started living a life on it's own, and this is even more inflated by 3DMark99 (a gaming platform benchmark, not a graphics card benchmark).

When overclocking my MAX on my P2@450 I still get a linear performance increase. I'm convinced it will perform much better when paired with a 600+ CPU, but CPU is definitely not the only factor.

Hi there

Maggi, thanks for the link, but I knew already about G400tweak...

That Mgatweak and the possibility of changing multipliers is what is bugging me right now
