p.sherbet Posted November 22, 2014 Share Posted November 22, 2014 Morning all, First post . I have a Clevo P150SMA, it's about 6 months old now. Luckily I have some really nice temps at the moment:- CPU/GPU never seem to go above 60c. So I though let's overclock! I have flashed prema mod BIOS and now have no idea what to do next to overclock. I'm used to overclocking on AMD desktop machines but not Intel/nVidia laptops . I normally dual boot linux/windows, linux is my main OS and windows I use for gaming so I would prefer BIOS overclock, although for GPU this is not that important. MSI Afterburner does not allow me to overclock. So I far I believe the best thing to do is flash a vBIOS for the GPU to allow overclocking in afterburner and overclock the CPU in BIOS. My question is how do I overclock the CPU in BIOS and any other advice. A guide to prema mod BIOS overclocking would be great but I can't find anything.

jaybee83 Posted November 23, 2014 Share Posted November 23, 2014 use intel xtu for cpu oc and nvidia inspector for gpu oc, settings and GUI are pretty self-explanatory Quote Link to comment Share on other sites More sharing options...
p.sherbet Posted November 23, 2014 Author Share Posted November 23, 2014 use intel xtu for cpu oc and nvidia inspector for gpu oc, settings and GUI are pretty self-explanatory Thanks, with nvidia inspector and unlocked BIOS I have so far got +100mhz core, +750mhz memory and -25mv voltage, but that was just after a few hours I will go back to it later. XTU seems very complex - not sure where to start. As above I would prefer BIOS overclock for CPU due to my main OS being linux and often dualbooting - however I would first use XTU to find a stable overclock. Does premamod BIOS support the same overclocking features as XTU and where should I start? Quote Link to comment Share on other sites More sharing options...
p.sherbet Posted November 24, 2014 Author Share Posted November 24, 2014 Ok so I have looked around and it looks like the best way to overclock is just to undervolt the system, due to the TDP limits.However I have noticed in windows I don't get turbo at all, just the stock 2.5gz (i7-4710mq), in linux turbo works fine. Any ideas why is turbo not working in windows (8 x64)? Quote Link to comment Share on other sites More sharing options...
jaybee83 Posted November 24, 2014 Share Posted November 24, 2014 mmm yes and no. on one hand ull theoretically be able to reach a higher clock when undervolting due to a larger headroom with the TDP limits, in reality though ur maximum available clock will also be limited by the undervolt. basically more volts = higher attainable max. clock but since ur 4710MQ is limited to +200 Mhz overclock anyways, it might actually be a good step to undervolt it as long as it can reach that oc stably concerning ur turbo boost issue: have u tinkered around with tools such as throttlestop or maybe set a wrong value in intel xtu? if everything looks fine, try and revert back to stock values and see if your cpu behaves normally then. another thing to try: enter control panel and hardware list, remove your CPU and reboot. cheers Quote Link to comment Share on other sites More sharing options...

p.sherbet Posted November 25, 2014 Author Share Posted November 25, 2014 Wow - prema, I'm honored. Back to the issue. I have installed Clevo hotkey and set to performance but I have same issue, but the CPU does not clock down with this set to performance (always 2.5ghz, before it would go between 0.8 and 2.5ghz).I have tried resetting BIOS, uninstalling CPU from device manager and XTU shows that turbo and speedstep is enabled.I didn't have throttlestop installed but have installed it now and by default it shows multiplier set to 25 and the disable turbo box is grayed out. Setting multiplier to 26 - 35 does then active turbo, although the disable turbo box is still grayed out until set to 35.Running on battery I notice I get only 1.5ghz, understandable due to power savings but I though it may be worth noting. Again linux still turbos on battery.I have no idea what to try next, I may have to reinstall windows.... Quote Link to comment Share on other sites More sharing options...
