As others have said, that is not normal. The two BIOS positions on the 290 aren't supposed to have any kind of functional difference, just one is write protected while the other isn't. If this is a card you picked up second hand I'd say that someone tried to flash the BIOS but made some kind...

Hopefully the addition of Japamd, the creator of RadeonPro, will spur them to expand the tweaking ability of the tool. I like the idea behind it, but the execution still seems to be lacking.

It does when you use the 40% fan cap. Different bins have different voltages (anywhere from 1.11v to 1.17v), and with such a low fan speed the higher voltage binned chips will have to throttle more. If the "Uber" BIOS is used the fan is allowed to spin fast enough that even with different...

Then what does the Aux actually control? AMD has implied that the IR controller is functionally similar to the CHiL used on previous designs so it doesn't make a lot of sense that they'd remove memory voltage and use it for another part of the chip without documenting it.

The Aux offset will up the memory voltage, as confirmed by GPU-Z's VDDCI voltage reading. Unfortunately +/- 100mV isn't enough to be all that useful.

You can still be CPU limited even though no core is maxed out. Windows will throw threads around so that no core will be completely maxed out, but even spread out that/those thread(s) can only perform so much and games only create a few. AMD's drivers also seem to have a fairly large CPU...

http://forums.guru3d.com/showthread.php?t=383465 They passed the WHQL testing, but are for the 290(X) cards only. They're also missing all the performance tweaks of the 9.x betas.

Don't pay attention to the GPU usage as it doesn't really reflect what is happening due to issue with AMD's driver. It will always look like it's throttling no matter what fan/powertune/clockspeed settings you're using. The best way to see if the GPU is being pushed is to watch clockspeeds, as...

I'm another that has no Overdrive tab with these drivers. I think you can get it back to proper by completely uninstalling the drivers, booting in safe mode, and running DDU before reinstalling. But as I use Afterburner for my overclocking I haven't spent the time to try it for myself.

Just to point it out, HDR means High Dynamic Range, no high definition rendering. It improves the contrast between dark scenes and bright lighting, and as such games can still look extremely good without it.

Most likely the game sees the Nvidia driver but doesn't know it's not the rendering card so it's allowing you to select TXAA, My guess is that if you tried to use it, you'd either got the base MSAA or no AA at all as TXAA has certain hardware requirements that only Kepler has.

It's most likely that some of the initial 290s were actually 290Xs that were castrated at the BIOS level to meet the initial demand ($400 cards sell a lot better than $550 cards) while later chip shipments were meant to be only 290s from the start and are laser cut. Those who received the ones...

Games need to be coded with this in mind for it to be taken advantage of. It's possible that updates could add this functionality, but that's probably game engine dependent. http://msdn.microsoft.com/en-us/library/windows/desktop/dn312084%28v=vs.85%29.aspx#tile

In my experience that is an AMD driver issue. I've had it off and on over the last few generations.

1. The only difference in the BIOS in fan speed cap, and that the quiet is write protected. I don't see how it would matter for software voltage control. 2. And as for what 100mV will get you, it depends on your stock voltage. Different chips come with different voltage, like mine is at...
