Een bios-update is beschikbaar voor mijn plank, waarin staat dat er een optie, of iig feature PCI-Fetch disabled is. Na een snelle zoektocht op het net over de invloed van PCI-Fetch kwam ik uit op de volgende site:
Bah. Dat heb ik weer. Ondanks dat ik 2 sloten heb waarvan 1 voor een S-ata controller, is het verstandig te upgraden, en zowiezo als er straks ondersteuning is voor mijn plank voor de nieuwe Phenom X2, moet ik dan inleveren? Als geen enkele bios met PCI-Fetch meer mag, dan kan ik er lik op stuk nemen dat mijn controllertje het ineens een stuk minder doet.It has come to our attention that Nvidia has ended up in more product trouble, although this time it's with regard to Nvidia's chipset division and it's not related to a manufacturing issue, but rather a lawsuit from OPTi Inc.
As the story goes, Nvidia has infringed a patent regarding to PCI prefetch that OPTi holds and although OPTi no longer makes PC chips, they now license intellectual property. The problem in this case is that Nvidia didn't come out on agreeable terms with OPTi and has to remove the PCI prefetch feature from its chipsets.
The problem with this is twofold. Firstly, it means that just about every single Nvidia chipset from the nForce 500-series and onwards is affected and as such, PCI prefetch has to be removed from all retail boards and every single BIOS upgrade that contains the PCI prefetch code has to be removed from the Web. This also means that all Nvidia partners have to release BIOS updates for every single Nvidia motherboard from the nForce 500-series and onward.
For consumers, this means that they'll get very poor PCI performance, so if you're using any PCI cards in your Nvidia-based motherboard, don't upgrade to the latest BIOS, as it will reduce the performance of the PCI bus. This isn't going to be popular with a lot of users out that that have already upgraded their BIOS, as this "feature" has already been implemented by some motherboard manufacturers going back a couple of months.
