es gibt neuigkeiten zum thema cpu overclocking. ich habe es aber nur begrenzt bei meinem t9300 hinbekommen. Problem ist bei mir, das IDA zwar im leerlauf dauerhaft aktiviert war, aber unter vollast (prime) nur der normale max. multiplikator umgesetzt wurde. vielleicht hat jemand von euch mehr talent. das tool macht einen guten eindruck und könnte rmclock sogar ersetzen. ???
viel spass

P.S. nich vom langen text abschrecken lassen. die links sind wichtiger :D
If you can't overclock your CPU try this:

I've been trying for ages to overclock the CPU in my Dell M1530 (T7250 CPU). SetFSB didn't work which is the most common method for overclocking stubborn laptops. I've found a program which doesn't seem totally common knowledge on the net, that allows for limited overclocking of the CPU. Basically any CPU which has IDA mode can benefit from what I will show you (That's any Core 2 Duo CPU basically).
Okay, so to start what is IDA mode. IDA mode is something that your Core 2 Duo does without you even knowing. If the load on the CPU is low, then the CPU will overclock just ONE of it's 2 cores to give more performance. Now, what I will show you will enable you to force your CPU to run at IDA frequency levels on BOTH of your cores for 100% of the time. So, for my T7250 which is 2Ghz at 100% load, using this program I will show you enables it to now run at 2.2Ghz for 100% of the time when at 100% load. It's been coined the 'Dual IDA mode' (google that if you want to know more about it outside of this thread).
OK, so the program is called ThrottleStop, which is a free program that seems to have been designed by an independant enthusiast. Not only will it give you 'Dual IDA' overclocking, it will also enable you to undervolt your CPU, thereby running using less power & running cooler. => Double Bonus!
You can find the ThrottleStop program at the following link in the first post of the forum on that link (just click on the ThrottleStop link when you get to the forum in the following link):

Also, in that link above (also in the first post), you will find a link to click on for instructions on how to use the program.
Now for the enabling of the overclocking by using ThrottleStop, follow the instructions located in the first post of the following link:
http://forum.notebookreview.com/windows-os-software/477704-how-enable-intel-dynamic-acceleration-ida-both-cores-core-2-duo.html
This all sounds a little bit complicated, but it's not really if you take the time to read the first posts at each of the links I've given you above.
Well, good luck with your 'overclocking' of you CPU, and post back to let me & everyone else know how you got on. As a word or warning if you're new to overclocking and/or undervolting then please research around this topic before you try this. Above all, monitor your temperatures using free monitoring software such as CPUID Hardware Monitor to make sure temperatures don't exceed safe limits.
Bonus 10% performance, plus the ability to undervolt in a small free program can't be bad!!

Replying to your own thread is poor form I know, but I can't edit my previous post I think, and I wanted to add to it.
I want to expand upon the benefits of this program and what I have achieved with it. I mentioned before that you could undervolt as well as 'overclock' (well, you can enable Dual IDA 24/7 at 100% core load, which isn't possible without this program - ThrottleStop). So for the undervolting, just wanted to let you know what I have achieved with my Dell M1530 with the help of this program:
Before CPU at 100% load = 1995 MHz
After ThrottleStop 'Dual IDA Mod' = 2195MHz
Before (stock) voltage on CPU (IDA mode) = 1.275V
Now (using ThrottleStop to undervolt) = 1.0375V with Dual IDA invoked.
By undervolting CPU, my CPU temperatures have dropped by about 15 degrees centigrade. Also, by undervolting CPU, (because my GPU shares the same heat pipe), I am able to overclock my GPU to insane proportions without it overheating. My GPU is now overclocked from stock values of 475 core / 950 shader / 700 memory to 700 core / 1700 shader (insane!) / 1000 memory (this is the 8600M GT GDDR3 version). Basically if you make your CPU use less power by undervolting, then your system could have more room for GPU overclocking without GPU temperatures going over acceptable limits (I would say over 90 degrees centigrade on your GPU is not advisable). With this setup, my GPU is at 85 degrees full load on GPU & CPU (Furmark & P95).
Apologies for replying to my own thread, but couldn't add this extra info otherwise. As a result of all these modifications (CPU undervolting & overclocking, as well as GPU overclocking), my 3DMark06 benchmark at 1280x800 resolution has increased from a stock 4527 to 7029 when overclocked. A 55% overall increase in system performance in terms of games is not to be sniffed at! None of this would have been possible without overclocking CPU (& undervolting at same time), and wouldn't have been possible without overclocking GPU. Just keep an eye on your temperatures! I reckon I've given my laptop a few more years of NOT being obsolute - BONUS! You can too, just be careful with temperatures.
Forgot to mention previously. I'm using a notebook cooler which lower GPU temps by about 5 degrees centigrade at full load - every bit helps when you're pusing your system to the limits! Mine is the Zalman NC2000 notebook cooler which is well known & recommended, I recommend it anyhows!
