Thinkpads Forum

Does anybody know how cool the chips in this run and how much headroom they have for overclocking? Has anyone figured out which software programs are compatable with the cpu and chipset?

If we could get a 200mhz-400mhz bump out of this chip, it would truly be the ultimate ultraportable.

I feel the same way about this. If only the X300 was clocked the same as the MBA, I would get it in a heartbeat.

Since I almost had a Dell m1330 w/ SSD for $1800 (returned it due to crappy screen and build quality), I am finding it hard to justify the premium price of the X300.

Count yourselves lucky you can buy an X300!

It isn't even listed on Lenovo UK.

It seems Lenovo only wants to sell its products in the US, and if we get it here it will be a ridiculous price, I suspect.

No problem, we can go elsewhere if you want us to, Lenovo.

On other laptops people have reached 950 FSB. So, assuming compatible software can be found, the next step would be to check the maximum voltage and compare it to the average people have been getting at 1.5ghz or so with NHC on other thinkpads like the T61.

It all depends on what PLL chip Lenovo uses and if it's programmable or not. If they use one of the hundreds supported by programs like setfsb we are golden.

I have some really nice soldering equipment and when I get mine, not only will I open it up to find the pll, but I am going to see if me and some people on xtremesystems.org can figure out a vcore mod for it, depending on how solid the cooling solution is. Provided the PLL is programmable and the cooling is up to par, I would think 2ghz is a lock. The core 2 duo's are some of the most overclockable chips out there (my e6850 is at 4.1ghz in my desktop without a sweat) and the low voltage ones are traditionally even better overclockers as they are higher binned silicon.

Worst comes to worse, I will look at the bios and see what other cpu's it will support. My university has FCBGA soldering equipment, so provided I can find another cpu that is in the same package as the stock chip, and provided the bios supports it, I should be able to swap it out.
