Thank you for your information/suggestions, I just got the 330W laptop adaptor from Dell and the tip converter from bitnext ( X75 Power Connector - 7.4 x 5.08mm Female Jack to 5.5 x 2.5mm Male Plug ) today, and did a test using Kombuster. The result is quite good, the overclock is now stable even at 948/2198MHz. I think my old adaptor is somehow partially broken and can't supply 180W power anymore (and that's probably why it's making a ticking sound every 1/5 second..).. The new dell adaptor is running cool (The old adaptor is super hot when gaming) and quiet and I'm quite happy about it. - - - Updated - - - For anybody with the same problem, Please refer to the post above. This thread can be marked as solved now.

Interesting... Might have something to do with the driver, cuz I let it to do auto updates.. It is not bothering me too much tho cuz it won't happen for most games. Just when testing with Kombuster.

Hi landsome, I am using MSI afterburner, and I was running Kombuster to test the overclock when the fluctuation happens. Is your laptop adaptor making ticking noise?

Hi Lyff, yep, it's from my adaptor.. The adaptor is quite far away from my laptop, and I can tell the noise is from the adaptor..

Hi svl7, thank you for sharing the vbios. Just a few questions: First, what is the voltage for 675mx after using the modified vbios? Or will it increasing dynamically as I'm adjusting the overclock to a higher value? Second, currently, I noticed that overclocking the 675mx at 797MHz, 2198MHz is not stable anymore after I locked it for 4 months. The clock speed jumps up and down from 797 MHz to 199MHz, and the laptop adaptor is making "ticking" sound at a high rate (about 4 ticks per second). I updated the laptop with the unofficial EC control from MSI website, but it doesn't help. I'm wondering if the adaptor is faulty? I opened a discussion below, but nobody replied anything. http://forum.techinferno.com/msi/6592-msi-gt70-one-laptop-675mx-clock-speed-not-stable-when-overclocking.html Thank you in advance for your reply!

I'm afraid you can't improve it without redesigning your program to take the advantage of multi-processor... Option 1, try using Parallel computing toolbox. Option 2, or you can simulate the multi-threading process if you don't wanna purchase parallel toolkit. In your primary code, start another matlab instance by invoking a batch file which opens up matlab and run a script. The synchronization can be coordinated by sharing a piece of memory specifically reserved for parameter transferring, or you can simply create a .mat file and share the parameters via hard drive (check the file every several millisecond). This is what I used for multi-threading during the development of one internal test frame, and I saved a lot of money for my team lol (cuz parallel computing toolbox cost some 1000 dollars a piece)

For sure you can keep it on. I always keep it on when gaming, it keeps my laptop at 78 degree C when heavily overclocked.

Hi guys, I have a MSI GT70 laptop which I locked for 4 month last term, when I use it again, I noticed that the overclock at 797, 2198MHz is not stable anymore. The clock speed jumps up and down from 797 MHz to 199MHz, and the laptop adaptor is making "ticking" sound with a high rate. I updated the laptop with the unofficial EC control, but it doesn't help. I'm wondering if the adaptor is faulty? Thank you in advance for your reply!

Thank you very much for your tutorial, glad that I read other ppl's post before doing the flash in windows mode lol
