It quite normal that the card isn't stable at 250 mhz with the normal heatsink. From what I can tell from the pictures is that its a very small one. Ant could ya tell me the size of that heatsink in mm

pretty cool thought it can run 240 with the normal heatsink.

I think the biggest improvements in games will come in future driver releases , I think the drivers aren't really optimized yet for games

The heatsink/fan does seem rather pathetic, I'll measure it up next time I have the lid off. The fan is actually "embedded" in the heatsink so by the looks of it in the centre there are no fins on the heatsink.

Here are a few more numbers to fill in at the bottom end.

250 200 = 149.648
250 220 = 160.942
250 230 = 166.480
250 240 = 171.667
250 250 = 176.025
250 260 =

275 200 = 152.680
285 200 = 153.721
295 200 = 154.556
305 200 = 155.041
310 200 = 155.204

Hey Ant, how about some surround gaming numbers?

It appears that overclocking the memory does not get you much of an increase. How about when running Q3 with three monitors?

[P5ycho]

it looks like a G400MAX heatsink evolution. Not a very effective design. (i've been studying heatsink designs lately)

Add at least a copper based heatsink for air or water and the thing flies if you ask me...

[Enak]

Well at least Matrox designed us something we could spend more time modding

Using absurd texture sizes when testing the gain on memory overclocking would be a nice idea too. It's all about finding those worst case scenario's.

The "OEM rate" numbers look pretty close to retail. Is the clock rate the only HW difference on the OEM cards?

Now here is the more graphical result of Ant's benchmark...
I added the lastest results for 200 MHz core and 220 MHz mem speed!

It no longer look's weird....
Thanks Ant!

210 hey? OK I'll fill in the gaps

[Drizzt]

Hey, Ant, what about those 3d glasses I suggested to try?

Seem's to me you've got to much time!

By the way: Which type of memory has the bulk version of the board?

[Ant]

Here we go...

250 210 = 155.408
275 210 = 158.745
285 210 = 159.840
295 210 = 160.862
305 210 = 161.189
310 210 = 162.211

Ok, Ant! I updated the chart (look above....).

Hi:

Where on the CD is Sharkmark? I can't find it???

Thx

So at 300MHz we should expect to see a performance increase of about 36% if the increase is linear and memory bandwidth isn't a problem.
