Reviews for the Rock Xtreme 840SLI

60% Rock Notebook Xtreme 840

Rock notebooks are built to order, so delivery time is normally around a week. Here I am looking at what would definitely be a top of the range unit, very powerful and rather expensive, it is all but £3000 and today that is not cheap.

Rock - Xtreme X840SLI-X9100 review
Source: IT Reviews English
We did an initial field test with Rock's new Xtreme X840SLI-X9100 desktop replacement laptop, using an 18 year-old female online gamer and a 30 year-old male Xbox 360 addict. We opened the lid, turned on the power and within seconds got the identical awed response that went something along the lines of, “Whoa, that is soooo cool!” There's no question that Rock's new hardcore gaming laptop will be heaven sent for serious gamers who want the latest and best from Nvidia's graphics arsenal, yet flashy lights don't make for responsive controls, despite the welcome macro buttons. The price tag is high, but you'll get a reaction (and probably arm strain) wherever you take it.

70% Rock Xtreme 840SLI-X9100
Source: Trusted Reviews English
With gaming laptops there's often a fine line between portability and power, but Rock's Xtreme 840SLI-X9100 falls firmly into the latter camp. This behemoth is most definitely a 'desktop replacement' in the truest sense of the term, as with a starting weight of six kilos (plus another 1.2kg for the power brick) it has the distinct honour of being the heaviest gaming laptop to have graced our labs - not counting the multimedia-oriented HP Pavilion HDX9095EA. It's big in every way, but despite its excellent Full HD screen, some innovative features and stonking performance in games, there are enough niggles to hold Rock's Xtreme 840SLI-X9100 back from coming recommended.

Two GeForce GTX 280M graphics cards in SLI combination. The performance is about 0-40% faster than a single GTX 280M, depending on the application. Due to the SLI setup, users may experience micro stuttering, especially in the 30fps range.

Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards.

Intel Core 2 Extreme: The fastest Core 2 Duo variants of Intel are called Core 2 Extreme. Technically, these processors are based on a Merom/Penryn (X9000) core like all other Core 2 Duo  processors,  too.


The X9100 is the fastest dual-core of the Core 2 series and thanks to a free multiplicator can be overclocked easily. Later the expensive X9100 was substituted by the cheaper and more power saving T9900 (with a fixed multiplicator).
