The x201 is a 12" ThinkPad model with i5 2.5 ghz, unfortunately only DDR2 but jam in an SSD and it's a crazy bargain for ~$100 on eBay.
Coreboot support too if that's your kind of thing.
Stay away from the tablet x201, forget that noise.
- yuhong 10y agoCore i5 would not be DDR2.
- dom0 10y agoCorrect, all three-figure models are at least DDR3. The X20x support up to 8 GB (2x 4 GB). Edit: And no, they really don't support more. The memory controller only supports 2 Gb chips, so with two ranks per channel you only get 2x 4 GB. (Intel i7-600, i5-500 series processor datasheet, section 2.1.1).

- yuhong 10y agoThe datasheets are often outdated. See http://www.businesswire.com/news/home/20100923006778/en/Samsung-Mass-Producing-40nm-class-8GB-DDR3-Module http://www.businesswire.com/news/home/20100923006778/en/Sams... for an example.
- dom0 10y agoYes, such things are often outdated, but the availability of different memory chips does not change existing hardware. The MC really doesn't support it, there is no way to change anything about that... I believe there were other chips at the time that supported more than 8 GB (i7-9xxM perhaps), but these are a different die (Clarksdale quad cores, ie. high end mobile chips that are selected desktop chips).
- yuhong 10y agoThe point is that the datasheet is now inaccurate. This happened before with 2Gbit DDR3 and Intel had to update the datasheet for the Mobile 4 Series chipsets.
- dom0 10y agoThe datasheet says that the IMC only supports 2 Gb chips, which remains accurate. Even a single 8 GB DDR3 module will not work with these laptops.
- yuhong 10y agoAnd if you read http://www.intel.com/content/www/us/en/processors/core/core-i7-900-mobile-ee-and-mobile-processor-series-vol-1-datasheet.html http://www.intel.com/content/www/us/en/processors/core/core-... , it does not say anything about 4Gbit DDR3 either.
- dom0 10y agoThe difference is that with the one DS we know it's accurate because anything beyond 2 Gb simply doesn't work. So that DS is accurate. On the other hand we know that with Clarksdale more than 2 Gb does, in fact, work, just like they work on Lynnfield. As one would expect, it's the same silicon after all. If you'd excuse me now, I believe my work here is done ;)
- yuhong 10y agoAnd here is another example (notice it almost works, proving there is no hardware limitation): http://apple.stackexchange.com/questions/42426/can-i-upgrade-my-macbook-mid-2010-to-16gb-of-ram-2x8g http://apple.stackexchange.com/questions/42426/can-i-upgrade...
- eltoozero 10y agoCorrect, had too many machines on the bench this week.
- dom0 10y agoX20x: make sure to get a Panasonic cooling unit; Toshiba's is awful. Apart from the noise they are built differently (so easy to tell apart), the coldplate on the Panasonic is split into the actual coldplate and a silver aluminimum piece that holds it down, while on the Toshiba the coldplate is copper all the way to the screws. But you only see that if you flip the system board over. ... and at something like 1.3-1.5 kg they aren't really heavier than more modern laptops anyway, just thicker.
- criddell 10y agoWhy do ThinkPads have such terrible resale values? That's one point that makes Apple machines more appealing - in three years the resale value is still decent, drastically lowering the TCO.
