Cpu undervolt method

[shivauthaman]

I want to undervolt my cpu core2quad q9550 I used Intel tunning software and throttle stop but it's not working I mean it's not showing undervolt option

Why would you want to undervolt your CPU? That is something that could cause instability and should only be done by experienced builders and overclockers, if at all. What exactly is it that you are trying to accomplish by undervolting?

Actually the thing is my motherboard support 65 TDP cpu and I installed 95 TDP cpu now its frequency is slower than stock speed this is because of overheating and I can decrease this heating issue by undervolting few point which will boost my performance and less power consumption

You cannot undervolt much, my i3 was stock 1.1V and I've managed to get 1.0V straight with few dips here and there under 1V and over 1.05V.
Its not recommended, you can get slower perfomance than being throttled by mobo itself.

If you dont have options in bios for voltage, there is no other option than lowrring multiplier of cpu , perhaps...

Actually there is a much better option, sell that motherboard or use it for a secondary system, and get a proper motherboard that supports your CPU.

What are your system specs?

Motherboard?

CPU?

Power supply (Exact model number)

CPU cooler?

my motherboard is BIOSTAR g41d3b ver 6.0

Q9550 quad core cpu LGA 775

450watt smps (oddesy)

cooler antec A30

That CPU is not on the support list for that motherboard. It would be highly advisable to get a motherboard that was intended for use with that CPU, however, page 29 of the user manual BIOS settings guide available on the Biostar website for your motherboard indicates that voltage adjustments ARE possible within the bios. You would also want to adjust the CPU frequency (Clock multiplier) as well or else you risk causing the system to become unstable if it runs at it's normal maximum frequency.

I'm not even sure that CPU will work on that motherboard since it is not on the support list.

If it does run, another thing you can do is limit it's power and performance by going into the control panel advanced power options and changing the maximum Processor power state to about 65%.

All of these are only band aids to the real solution which is to get a motherboard intended for use with that CPU. That is the only actual solution and unless you can find one fairly cheap, it's probably not a good one as this is very old hardware and simply upgrading to something newer probably wouldn't be a bad idea.
