Why does ATI limit overclocks and Nvidia do not.

There's nothing wrong with it, I'm just pointing out one reason why ATI cards have the soft lock on overclocking :confused:

You're right, pardon my harshness.

Anyway, I'm very happy with the situation, if the cards (5850s for that matter) were released with higher stock clocks (which is easily achievable, most [not saying all because I can't know it] do 5870s clocks with less voltage than 5870s need), they would certainly be priced higher. For those who are scared of overclocking, can't be bothered with it (stresstesting for example or higher load temps) etc. there are cards factory pre-overclocked. Another matter is the fact that a premium they charge for those is by no means worth it IMO.

Not too sure on the 5770, is the XFX a pre-overclocked model? it maybe that is what the limit is on the 5770.



Another that feels the need to derail a perfectly legit thread, if you have nothing constructive to add please stay out of thread.

It seems very sensible to set a maximum OC limit to restrict RMA's from the 'casual/ novice' overclocker. People with more experience will go off and find ways around any artificial limit imposed.

Not trying to derail anything but this is kinda a troll/ flame bait thread. With no offence intended, who cares why they do it? When you start a thread like this you know exactly the way it will go, down hill rapidly. As Drunken has mentioned, it is funny that this was never worth discussion when you owned an ATI card! :D

My "locked" 5850 goes from 725 to 1050Mhz, yup, 45%, I really should move to a 460gtx that will be around 50% slower at 1920x1080 with 4/8xaa, because its unlocked and therefore will clearly overclock further.

Yes, but you know what you're doing, Joe Bloggs on the street doesn't, hence will hit the soft limit in CCC.

Actually I do believe I made a thread or reference to it way back when. I was kind of miffed at having to potentially void my warranty to be able to overclock my 5870 past the measly 50Mhz limit.

My 470 overclocks to 850 pretty easily on 1.087v, so a 10% increase in volts gains a 40% overclock. :)

You mean more like 15% increase in volts. Still, overclocks as well as 5850 I see. The problem is most 470s don't seem to like these high clocks (stable) as far as I've seen in these forums. A few users didn't achieve 800Mhz at this voltage too.

There's your answer.

ATi hope that if you want to go faster than what CCC allows, you'll buy the next card up in the range, or go crossfire. Both which make them money.

Maybe NV allow you more headroom because they know you'll need it once you hit the 'physx' button...:p

Sorry, couldn't resist :)

I'm not sure what your point is, with Nvidia, Joe Bloggs if he overclocks might whack his 480gtx to max available voltage, set the fan low, and whack it to 1000Mhz and not know whats going on.

Joe bloggs with AMD is completely safe AND gets a small overclock, for free, covered by warranty, thats completely safe and available right there in the drivers.

Users of either brand can take things further and overclock to where they want to.

Not sure what your point is either, officially you've voided the warranty on your Nvidia card by overclocking, yet you're upset you have to potentially void the warranty on your AMD card to do the same thing? I also assume you mean flashing the bios? GPU clock tool can overclock beyond these limits and has been available for about 3 years, overdrive was available just about on launch and allows you to bypass the limit in overdrive without flashing the bios.

Whats the issue?

It also struck me as funny, off the top of my head when you had an AMD card I can't remember threads by you stating issues with your cards, since you got the Nvidia card you've made to threads regarding problems with your card(stuttering/lack of gpu usage and vsync(that might have been the same thread, I can't remember).

Before you had an Nvidia card you didn't USE or mention xfire drivers constantly, since you've gone Nvidia, without using SLI or Xfire, you can't stop posting about how Nvidia drivers work, and AMD don't.

THen you start a thread complaining that you have to void warranty on an AMD card to overclock behind the limits in overdrive, yet you had to void your warranty to overclock your Nvidia card, and afaik you're using the SAME APPLICATION to overclock as before, and somehow this offends you greatly.

Somehow a free overclock covered by warranty on the AMD side, vs no overclock covered by warranty on the Nvidia side is better for Nvidia.

Its getting beyond ridiculous, I mean, way way beyond.

You're using the exact same tool to overclock both cards, yet saying somehow its awful for AMD, we all know you overclocked beyond those locked in limits with your AMD card, and you almost certainly did it using the incredibly simple option to do so rather than flash your bios.

You have a card, you like it, you're nit picking every little thing possible and making up rubbish(all AMD users, you specifically said it absolutely effects everyone get flickering IN GAME under load, you went out of your way to say that, post a video and try and make it sound like its typical of AMD before insisting it absolutely effects everyone, this while ignoring your own issues and the stuttering fixes in the lastest Nvidia beta drivers).
 
Sorry mate, you're wrong, I like the simplicity of doing an overclock and having powerplay work and associated things, with overclock tool that is not possible, like I said I don't care if I overclock either card because they are not going to know it's been overclocked anyway, arguing that ATI limit clocks for warranty purpose is just silly. Flashing the bios can void the warranty if they get it working and they check it. It seems you need to do a bit more research as you claimed the overclock limit is through the drivers when it is in fact through the bios.
 
I think anyone paying good money for an enthusiast card like the 5850 and above will know how to clock it lol. To have ATI dictate how far I can clock my card is rather lame TBH.
 
Isn't it the same with different mobo makers though? Some let you overclock/tweak more than others, sames goes with CPU's come to think of it, some have unlocked multipliers and some don't

Im pretty sure (not 100% LOL) that the bios can be overidden on most hardware by drivers/software, like when speedfan overides the mobo bios to set fan speeds.
