I'm having an issue. After upgrading to 10.10c, my limit is still 800 MHz in CCC. What am I doing wrong?

I get my 6870 in a few days. It's the first launch video card I've ever bought.

BTW, for those of you having issues with the clocks revving up when idle, that's been an issue with the memory clock since the 10.5 drivers came out. It runs at max speed when overdrive is enabled, but the core revving up as well is new. I still show a normal core speed when idle using 10.10a.

Question: will I need to reinstall my drivers when my card comes in if I already have 10.10s up and running for my 5770? Or can I just plug'n play?

My Sapphire 6850 seems to be a pretty beastly overclocker. I have it at 930/1080 and it seems stable. I had to reduce it from 950 due to artifacting and 940 due to driver crashing so 930 so far seems good for stock voltage.

My idle clocks seem to work fine at 100/300 on the stock profile, however with Afterburner, it doesn't seem to automatically revert to the 2D profile once I exit my 3D games. If I hit the shortcut key to load the 2D profile of 775/1000, it'll go back to 100/300 when it gets a chance to calm down, but it won't go from my overclocked profile back to my 2D profile on its own. This is either a driver issue or a beta Afterburner issue.

using assigned 2d/3d profile in Afterburner loads fine for me.
both 2D and 3D.
my temp is at 775core around 50-52c
gaming is around 70-72c with overlocking, fan speed at around 60%

My 6850 sapphire does 975 on core but 1ghz is no go.
I need more voltage than afterburner gives me for 1ghz.
using 10.10 whql but 10.10c hotfix worked fine also.

Noteable is that fan speed at 100% is more silent than my old 5850 at 35%

What are you using to get past the 850 MHz limit in CCC?

Not true, I am at 900/1100 with my Asus 6850 using only the CCC. I have allowed max settings of 1000/1250, could be due to the bios on the Asus card.

Hmm.. you're correct. The TPU review shows the same limits for their ASUS 6850. BIOS differences could indeed explain it. Sapphire 6850s seem to have 850/1200 as their limits but it makes me wonder how changing such a simple setting in Afterburner could enable cards to go beyond such limits.

I read the TPU review and didn't even pick up on the fact the Asus allowed higher settings in the CCC. I got the card and went to overdrive and was like WTF, I thought you had to use aftermarket software to go past the CCC limit of 850. I had Afterburner already downloaded and ready to use. Needless to say I am happy, I only wanted 900/1100 and I got it easily. :thumbsup:

Yesterday evening I tested the Morphological AA in some games. At first I tried it on Fallout: NV since it was the game I play the most for now but I had Civ5, Resident Evil 5 and Metro 2033 installed too.

In FalloutNV, MLAA just doesn't fit at all. The image is all blurry and the overall quality is taking a huge hit IMO.

But in Civ5, RE5 and Metro 2033 it's just wow! It just fits! Less jaggies, better IQ overall without taking a huge FPS hit.

I'm really surprised at how well Metro 2003 runs on my computer at 1920x1080 with MSAAx4 and everything at High settings. Games look amazing!

Lonyo,

From what I can see, the MLAA does make edges smoother, but also makes everything fuzzier/more blurry and eliminates some graphic detail. For gamers running high resolutions MLAA doesn't seem like much benefit due to the hit to image quality.

So I guess the TPU review having their Asus card OC the highest doesn't seem to be true.

It was highest out of 2 cards tested (HIS and ASUS). :) Oc'ing is usually a crapshoot though, I'm sure some lucky bum out there has an ASUS at 1000@stock while someone has a dud at 820@stock or something.

I should of said this review below, using a bunch of cards from sites, not just TPU. I just meant out of all the cards tested, TPU had the Asus being the highest.

Xbitlabs has now got a review out, and interestingly they say this (inaccurate) statement:

Anyway, MLAA is based on post-processing and has both highs (particularly, it doesn’t affect the frame rate much) and lows (it cannot work with 1-pixel-large elements or with thin elements against a contrasting background, e.g. with text). Perhaps we’ll see some peculiarities in AMD's MLAA implementation during our special tests.

In the example Fallout screenshots it looks fine, but it's a case of it might work properly most of the time, but certainly not all of the time (since it doesn't not-do text in SC2).

Needs more investigation into where it does and doesn't mess up other elements.

Just got my Sapphire 6850 today, to replace a 4870-512.

It solved by biggest gripe with the 4870: noise. The PowerColor 4870 BIOS (which they never updated) ran the fans too slow in auto mode (quiet with cooking GPU, then screaming fan to cool down, then repeat). With manual mode I had to run at a noisy 39% constantly for 3D. I also had to run the rear case fan at a noisy level to keep things cool.

With the 6850 using the auto fan control it runs silently for 2D and quietly for 3D, while staying 10c cooler (53c) after an hour of gaming with the case fan near silent. Nice!

I also can run Fallout 3 with max quality settiings at 16x10 more smoothly than the 4870 ran at 14x9. Possibly even at 19x12, I just haven't tried it yet.

A 6850 makes a great upgrade for 4850 and 4870 owners, at a very reasonable $180.
