I'm thinking these 470s were binned as 465s because the core is somehow not stable with voltage/frequency, just like phenom II 550/555. Never guess it could be the temp.
It seems to me like the majority of the OCN members who owns one of these cards (and has also unlocked it) has trouble keeping it stable when the temps exceed 75-85Â°C. Simultaneously, the majority of these cards aren't as good at overclocking as reference GTX 470s.
So, I don't know if it's a fact, but it sometimes seems to me like it might be - especially in situations like kidwolf909's.
But I don't know yet what reference 465s are supposed to be able to handle. However, if it is
105Â°C, then this might be why MSI put the "all-copper" Twin Frozr II on them instead of just some reference cooler. I mean, I think the combination of binning them as GTX 465s and using this cooler makes for a product that they felt confident about releasing to the public as opposed to binning it as a GTX 465 and just putting a reference cooler on it.
So, I think that the way they handle heat must be a part of the reason why they don't overclock as easily as reference 470s as well as why they binned them as 465s.
Of course, we have never heard/seen an official reason (or reasons) from MSI about why these were binned as 465s, so this is all just speculation. But I think we can get a pretty close idea by just observing the results from each and every owner who has unlocked their card and also overclocked it.
For example, my card's clocks seem maxed out at 765/1530/1848 with 1.100V. But I've talked with a couple of people who have reference 470s who were able to exceed 800 core without even adjusting their voltage one bit.
So, there have to be some sort of testing process which determined the ultimate fate of these cards.Edited by TwoCables - 12/18/10 at 11:32am
