Overclocking T9900

Has anyone overclocked their T9900 processor? If so, what have you reached (3.x) and do you see a major improvement in speed as opposed to 3.06 GHz? Could someone also post step-by-step instructions on how to overclock this specific processor? Lastly, does this void my warranty, and if so, how do I prevent the OEM (ThinkPad) from finding out? I'm on a ThinkPad W500.

 

1)Get SetFSB
2)Get the Clock Generator/PLL for your motherboard (Lenovo subforum probably would help)
3)Overclock
4)Stress with Orthos and monitor temps with HWMonitor
5)?????
6)Profit

Ignore steps 5 and 6......just for laughs

Anyways, software overclocking is really undetectable and do not have any adverse affects on your computer unless you change voltages (which you can't do in SetFSB) or overclock beyond acceptable temperatures.

 

I oc a t9900 to 3.67ghz in a gx720 through the OC options in the bios. Temps were a bit high though.

 

Do you think you could help me?

 

Unfortunately, your thinkpad doesn't have any OC options in the bios, so you will have to use the "SetFSB" program to OC.

 

I wouldn't be surprised if you got it to 4ghz.
if you have problems with setfsb check the thread in my sig.

Also describe the problem here, it's easy to troubleshoot problems with setfsb.

 

I guess I don't know how to use it. I'll do some reading on it and come back here for questions.

 

Are there step-by-step instructions on how to use setfsb, specifically for a ThinkPad? Honestly, I'm new to this whole OC thing, but want to get the full power out of my 3.06 GHz T9900 Processor.

 

first you need to find the PLL (clock genorator) that your system uses.
It's a small chip on the motherboard which is sometimes near a crystal that says "14.318mhz".

otherwise you can try every available PLL in setfsb until one works.

1. select the PLL
2. press getfsb.
3. move the top slider to the right a bit.
4 press setfsb.
5. check with cpuz if your frequency changed.

please describe what happens. we can troubleshoot.

Setfsb didn't work with my notebook. I had to move a resistor to allow overclocking and then I had to troubleshoot setfsb. now setfsb works for me.

check the thread in my sig about setfsb and clockgen, it will help you.

 

Does anyone know the PLL for a ThinkPad W500? I can't seem to find it. Please help!

 

do you have any pictures of your motherboard?
I can try to help you find it.

 

I'll take some today and upload them.

 

The PLL chip usually is a elongated inch long, aluminium looking but narrow chip that stands up some way off the motherboard. Along the top of it your PLL number should be written. I have heard the chip can also be square. Look near your CPU socket and near the ram.

 

Most of the PLLs I'v seen dont look anything like that ^^^.

check the thread in my sig about setfsb and clockgen for photos of my PLL.

The PLL is usually black. most likely is an ICS or silego chip. has many pins (very small pins).

Sometimes it's near a 14.318mhz crystal.

 

Lol, mine was. I guess my laptop has a modified P35 chipset which is originally a desktop chipset so it could differ from most laptops PLL chips. Ignore my description...;p

 

I wouldn't say ignore it.
the OPs PLL could be the same as yours.


@OP, I think you could get to around 3.5ghz.

 

1) Not worth it
2) A pain in the to do
3) You'll propably fry/brick it.

 

Um its defo worth it if 3.5ghz+ is attainable which is very likely. Also bricking a CPU is pretty hard to do unlike a GPU.

 

1) Worth it, depending on the task
2) Pretty much
3) Nearly impossible to achieve

 

My point is: Its too much work for what you WILL attain.

 

I know some people enjoy the effort they give to OC. It's a hobby to tweak the hell out of everything.

 

Those who enjoy overclocking don't ask about it. They just do it.
