they haven't blocked anything go and read the original article...found here
original article
its just the usual semiaccurate (ie Charlie's website) sensationalist headlines
so as i said earlier the overclocking functions haven't been removed, else msi's afterburner app wouldn't work.
NO, Lars is new and so far proven to be a complete twit, I wouldn't be remotely surprised to see him gone, very very soon. His writing is simply poor, his rumour type write ups(read the Apple one) literally don't have a single shred of info, its forum rumours, and yes theres a difference between writing an article based on forum rumours, and one from industry sources that starts forum rumours
I've so far seen from his first article to the latest, nothing but twaddle and a poor understanding of the situation he's commenting on.
Bru, its not Semiaccurate scaremongering, its talking about SOMEONE ELSES article and their conclusions. But having read it its Lars typical absolutely useless ability to draw conclusions from what others have writen. He's just thick as **** in all honesty.
THe original article is showing significant clocking problems, core/memory are the "non important" to a degree overclocking features, most Nvidia cards all the power is locked up in shader clocks, removing it is pretty big. But the article doesn't say it fantastically clearly, but seems to be hinting that these are set for Fermi OVERCLOCKING, and that it will just do it significantly differently on Fermi which is working against CURRENT overclocking functions.
Its not suggesting no overclocking but that its changed it to be compatible with Fermi, because if you're read on Fermi, a LOT of features that used to be on core clocks, are now on dividers under shader clocks, I would imagine that needs to be taken into account for overclocking.
Lars has misinterpreted it(and as I said its not fantastically clear in the original article) that they meant they've changed it so you won't be able to overclock Fermi so they've tried to inhibit shader overclocking. Which more than ever Fermi will be based, in terms of performance, almost completely on shader clocks as very little is left to be governed by core clocks.
Either way you've got, its not an original article, but commenting on someone elses, not brilliant english and a complete tool who misreads almost every situation it would seem.
In terms of Fermi, overclocking will be interesting, according to the white papers its a very low voltage design, but in doing so became an incredibly high amperage design. So now overclocking is supposed to be a huge extra power draw in amperage, I wouldn't be surprised to see some pretty significant "safety" limits in terms of overclocking to keep power usage in check.
