Thinkpads Forum

just curious if it would work to replace a T9300 with a X9000 processor in a t61p. why or why not (ignoring the cooling issue temporarily)?

another question is can one expect in the near future that there will be a, say, T9550 non-extreme processor, that has 2.8 or 3 ghz?

and then, anyone knows links about overclocking the T9300 or T9500 together with the thinkapd (ignoring the cooling issue temporarily)?

speed is really the only thing I care most for what I currently need to do, worth $800 to me for a X9000 if it would exist (within the limits of a 15" notebook).

thanks

Hi toby909,

I am considering the same questions with regards to the t61p.
It seems that the only way to overclock the thinkpad is through the fsb since the bios does not allow to change the clock multiplier.

there is a tool which makes that possible called setfsb but it works only if you can determine what it the pll of the planar.
If you manage to know it and if supported by setfsb, the job is done.

I am striving to overclock mine and went as far as to consider replacing my current T7700 with T9300 or T9500 but it seems that the gain is not that obvious.

If it were possible to merely insert a X9000 in the T61P with no cooling issue, I would not hesitate.

wow, thanks for the helpful info.

what do you mean, what is the "pll"? my chipset is the pm965.


thanks


(your memory is 4-4-4-12, but is it also actually running at 4-4-4-12 or 5-5-5-15?)

The pll is a series of number in the motherboard of every notebook.
Setfsb uses this pll along with clock generator menu, afterwards you have to increase step by step cpu frequencies.

The problem is that it is not that obvious to find the pll in the motherboard. you can check all this stuff at the site of the conceptor of setfsb at : http://www13.plala.or.jp/setfsb/

ps: My memory is running at 4 4 4 12 (fsb:Dram = 3/4) according to cpuz.

Cooling is the problem though. The X9000 runs quite a bit hotter than the T9500.

the cooling is not a problem!. the t9500 is a 35 watt processor and the x9000 is a 45 watt processor and , the thinkpad fan runs with 3500 rpm when the processor is under full load, with thinkpadfancontrol, this can be manually increased to 4500 rpm if the/a processor needs it. see the pattern?

but my question actually was if the x9000 is compatible interfacewise (not temperaturewise) to the t9500?

My RAM timings are 5-5-5-15...I have DDR2-667MHz RAM running at, you guessed it, around 333. Soooooooo...What's the magic trick to get mine "up to speed". This setfsb looks great.

Bumping your RAM past your FSB/2 usually will not do much, and since your RAM is most likely running at dual channel 333mhz(667mhz) you won't get much of a benefit from upping your RAM to 800mhz, and in fact you might even get a performance increase by lowering your speed to FSB/2 and see if you can set more aggressive timings.

Thermal dissipation does not work that way - but feel free to try it and see how hot it gets.

I have a t61p with a t9300 processor. Has anyone put this X9000 chip in their T61? Is there anyway to do this without overheating?

I think we aren't considering this moment - X9000 draws (can draw) much more power than T9300(9500).
DC/DC converters on motherboard may overheat and fail...

Thanks for the reply. I guess I will stay away from that processor. I read multiple reviews about how easy they are to overclock to 3Ghz, 3.2Ghz, 3.4Ghz by simply changing the multiplier. In a Dell 1730 XPS it takes five seconds to do, but apparently eventhough the Extreme processor has the multiplier unlocked (unlike the T9300/9500), as I've read above Thinkpad has that feature difficult to access BIOS unlike the Dell which has it open in the BIOS. I don't want to break my T61p, so I'll stick with the T9300. The X9000 uses 44 watts whereas the T9300/9500 uses 35 watts, but when you start changing the multiplier that raises quite a bit...I guess the Dell is designed for it and the Thinkpad isn't.
