I am wondering what the safe voltage is for the socket 775 Q9550@2.83 ghz would be for 3.5ghz

Q9550
8GB DDR2 PC8500 1066MHZ RAM
MSI P45 PLATINUM 775 MOBO
850W MODULAR PSU SILVERSTONE STRYDER
COOLERMASTER V8 CPU COOLER
XFX RADEON 4870 XXX - AKASA VORTEXX NEO SERIES COOLER

Well the max for the Q9550 recommended by Intel is 1.3625 but i would imagine you should be under that to hold stable somewhere around 1.33 to 1.35 should keep you stable but all CPUs react differently could be less could be more.

I have a q9550 at 3.4 (400x8.5) ghz and only 1.12 volts it runs perfectly stable. just try and see what you can do. use common sense. I strongly suggest not going above 1.2 I did and it got pretty hot but i was pushing 3.9ish ghz. never hit the 4.0 though (old mobo xfx 680i lt)

I have got the msi p45 platinum mobo and it lets me overclock but I can only overclock my ram from 800 to 1600 mhz and it wont let me overclock my cpu

Max VID is 1.3625 volts. That is the maximum voltage that the CPU chip will program the motherboard power regulator to produce.

Intel's max recommended voltage for the 45 nm Core2 Cpu's is 1.45 volts. That is not the same thing.

Here's where the "1.45 volts" figure comes from.

You can learn all kinds of neat things poking about the technical documentation.

badoosh, forget the RAM overclocking on a Core2 system.

I am unfamiliar with Asrock motherboards, but he is what you need to do ...
Download and run CPU-Z. It will monitor your RAM settings. You want a 1:1 FSB:RAM ratio.

Go back to stock settings, then adjust the RAM frequency to twice the FSB freq. FSB will be 333 MHz. RAM will be running at 667 MHz. Now start pushing FSB and core voltages up. You should easily reach 3.3 - 3.4 GHz. If you have an E0 stepping CPU, you should be able to reach 3.5 - 3.6 GHz.
