I've been able to get around 6500 with my 675mx and no overvolt, but it's not stable. To do it I overclocked +405 core, +800 mem. 3d Mark will somtimes give a result of around 6500 with that overclock, but if I run Heaven or another very taxing program the driver will crash. I've found that max stable for my card is around +395 core, +600 mem. I reduce that to +385/+500 for daily operation and still get a 3D Mark of 6200-6300.

Got it. I didn't realize how bad kombuster could be, but at least it proves that the throttling is working to limit the max temp to 90. I reduced the overclock to +375 core / +400 mem and get a 3D Mark score of ~6250 with a max temp during the benchmark of 78. I'm pretty happy with that, although Heaven Benchmark still peaks at 83. The averages during both tests are about 5-7 degrees lower than the max. I can of course max the fans and drop the temp quite a bit, but that seems wasteful and very loud.

I think the 15inch Clevo models just run hotter. Even with no overclock, I'm hitting 89-90 degrees with Kombuste after 5-10 minutes. My temps in actual games seems to peak at about 85 regardless of overclock unless I push it all the way to +400 GPU. If I do that the temp will hit 90 in games.

Yes it's a Clevo. The first run seems to have been an anomoly, it's peaking at 85 degrees C now with the average temp about 80 with gaming use and in the benchmarks at +400 MHZ. Looks like the absolute max I can get it to benchmark at is +405 before the driver will crash. I'm thinking of running it at +375 for daily use to provide a little more margin of error.

Seems like my limit is somewhere between +400 and +450. At 450 the driver crashes. Anyway, this is the most stable run I got at +400. The temp did peak at +90, do you guys think that's ok for daily use or should I ratchet it back for a lower temp?

Ran a few tests. I'm able to get the core up to 1004 (+350) with memory at 2450 (+650) for a 3d Mark of 6170 vs a stock 3d Mark of 4269. At those settings the temp maxes at 87 deg C . I know people have pushed the memory higher, but I've only seen minor improvements with it up to 825 and I got artifacts as low at +700 on one of the PCs so I'm going to call it good at +650. I think +350 on the core clock seems like it's already pushing my luck, but I might try higher just for testing.

Hey gents, I'm new here. I've got 2 Sager/Clevo 9150s with 675mx and i7 3610s to work with and so far haven't messed with the vBios. With normal overclocking I'm able to get about 5050 in 3d mark. I've taken the RAM on one of the laptops up to 825 and it was pretty stable, but the other one seems to top off at around 675 before I get artifacts. I'm going to try the vBios from the beginning of this thread and see what taking the core clock up a bit can do for me. I'll post my results later today I hope. Thanks for great work on these!
