    I'm running an hp pavilion dv2615nr with Nvidia GeForce 7150M 128MB (Shared) and 4gb of corsair ddr2-800, an amd turion 64 x2 tl-68 2.4Ghz. I'm running into stability issues when the ram is at around 900Mhz. So, I need to force it to 667 so then I can have the headroom for stability and overclocking. I think I can push to 2.8Ghz possibly if I can get the ram to ddr2-667.

    I modded this hp pavilion laptop with an open free air-intake (removed plastic fan grill), copper shim on gpu only, cpu/gpu cleaned and re-pasted using 91% alcohol and Arctic Silver Ceramique 2. I also modded the fan to 5v constant by removing the "Yellow" wire from it's connector.

    Right now i'm sitting at 28 Degrees Celsius idle on the cpu, gpu is at 44 Degrees Celsius at the moment. The cpu at idle is 800Mhz and the GPU is overclocked from 425Mhz to 525Mhz. I also disabled Powermizer so it sits at 525Mhz unlike before it would sit at 100Mhz and not ramp up in game sometimes. I edited the registry to allow for no powermizer when on AC power and Powermizer when on battery. I ran 10 runs on intelburntest standard at 2.6Ghz and the cores were about 74 degrees celsius max. I also bought a new 120W power supply which is 18.5V @ 6.5A and the factory power supply was 18.5V @ 3.5A. So that will help stability as well. It's much more stable with the 120W charger with the new cpu and the huge gpu/cpu overclocks.

    Thanks

    *Basically is there a pin mod I can put white out or something on one of the pins of the ram chips to force the bios to think they're 667 chips rather than 800? That or possibly an older bios flash possibly... I'm running the latest bios at the moment.

    Could I edit my bios file .f28 i think it's called with Phoenix bios editor to all for maybe the option is locked in the bios and I need to unlock all the locked features so I can change the ram multiplier.

    I downloaded and started SPDTool_063.

    I get an error upon startup saying no memory modules found, possibly an incompatible smbus driver? I'm running the latest available driver from nvidia maybe I'll try and re-install or something...

    I'm on Windows 7 x64 and it looks like the smbus driver isn't installed... what should i do to install it? tried doing so via device manager adding a legacy device since i have the driver on my pc for the smbus.
