Sony Vaio S Series SVS1511AGXB
Processor 1.6GHz Intel Core i7 720QM
Memory 8GB, 1,333MHz DDR3
Hard drive 750GB 5,400rpm
Chipset Intel HM77
Graphics Nvidia GeForce GT 640M LE / Intel HD 4000

Overclocked it to 1000MHz Core 1000MHz Memory via. a bios hack around 4 months ago but it runs REALLY hot, even with it's fan on full. Is this bad for my laptop's health? How bad is it?

ps. Stock clocks are 500mhz for core and 900mhz for memory

and got all my instructions and bios patch from http://forum.notebookreview.com/sony/677079-sony-vaio-s-bios-mod-gt640m-le.html

You only gave enough information for a vague answer. If the temps are too high, then reduce the overclock. If they're not, and you're not noticing instability issues, then it's fine.

Alright, the stock clock is not fast enough for me. My laptop's native resolution is lower but I usually connect to an external monitor during gaming, which I run at 1080p. However I find thermal throttling kick in after around 45 minutes of gaming and performance takes such a hit that it's almost unusable. I find lying the laptop on it's back helps a bit but all in all it's pretty bad. I read somewhere that the gt640m le is underclocked a lot and is capable of much higher clocks, so am I doing something wrong?. Should I try a lower clock speed? How much of a difference do cooling pads really make? How badly is this affecting my HDD and battery ?

Well overclocking a laptop has two major disadvantages:
1. The cooling system of a laptop is not designed to handle the heat, even if the components can in theory be pushed higher. Generally laptop components are designed to withstand some additional heat, but they are not made for overclocking. If your temperatures are fine and you are stable then you can leave your overclock. However as your CPU is throttling itself due to the high temperatures you should lower your overclock as your cooling is insufficient, and it can potentially damage your components

2. By overclocking your system you are increasing the power consumption and the heat that your laptop outputs. Both of these things are not good for a battery. The more current you draw from the batter the shorter your batter life (obviously) but also the shorter it will last as you are drawing more current than it was originally designed for. Second of all as all the components of a laptop are placed close together the heat from your CPU and GPU will also heat up the battery which too, is not good for it. This will also heat up other components of your laptop such as your hard drive.


I suggest you install a temperature monitoring program like Coretemp, or Realtemp and monitor your temperatures. Also lower your overclock a bit, if you see that your pc is throttling or shutting down itself to protect its components then you should change something. You could buy a cooling pad, but still you should lower your clocks a bit.

Hope this clarifies things!

If your already throttling on your GPU then you can't overclock as it will only throttle easier, and faster. My brother has a GT630m and it normally throttles at 92c. And he can't game on it because it'll throttle too much. You must have bought one of those thin laptops. My brother has a DV4 HP and it throttles and BSOD's after gaming for 30 minutes. I have a DV6 with a GT650m and it doesn't throttle at all and I can overclock the graphics. If your gaming you want to overclock the graphics not the processor anyways. But in your case you shouldn't overclock the graphics or the processor as your laptop design is obviously lacking. We've even sent my brothers laptop to HP and they couldn't fix it. So this isn't a fixable issue. It all has to do with the laptop you chose. You can try to return it.
