Undervolting and frame limiting

[devoncoke]

Hi I'm new to theese forums but from what I've read there are quite alot of competent people around so I'm pretty sure I'd get some good suggestions.

Well I have a Toshiba a300-15b on my hands and I use it dayly for CAD drawing and rendering with occasional gaming. I've done undervolting on desktop PCs via the bios but never on a laptop and with the help of software.

I hate it when the laptop handrests get uncomfortably hot after 2-3 hours of drawing or an hour or so of gaming and was hoping someone could help me about it.

I found a very useful guide in this forum which suggested using the program RMclock v2.35 but unfortunatelly the program didn't recognise the CPU: Mobile C2D T8300 Penryn-3M C0 stepping (i.e. showed blank under the CPU info tab) so I didn't dare try anything with it. If anyone could post a program and some tips and tricks on undervolting the T8300 it will be greatly appreciated.

Also when gaming I use this dll hook to limit my frames under Dx games to 30 which greatly reduces heat output from the GPU but it only works for Dx9 goames nad not for Dx10. Would be great if i find an alternative. It was quite difficult to find it in the first place. Also http://www.xtremesystems.org/f...ndex.php/t-176498.html">here's</a> a link to the discussion page of the hook

darn the forum link doesn't want to work try copy pasting:

Edit: Well did a bit of googling and found out that alot of people used RMclock, so I gave it a try and it worked like a charm. Did a mix of Everest, Prime95 and for now it seems to run pretty stable at a v.core of 1.000V at 12x multi and a v core of 0.950 at 6x. For some reason I can't go lower than 0.950. I'm guessing penryns need all that v.core to feed the extra l2 cache. Temperatures dropped by 10-15 degrees C. Need to do a more serious stability check tho.
