What software do you use to bump up memory/core voltage and clock speed? Also, what is a safe voltage for memory and core?

A custom fan profile isn't going to do much for you. When the fan speed throttles up under load, it is needing as much air flow it can get since it hovers around 94c. You will either have to deal with it or go aftermarket.
Afterburner.
There is no programable voltage controller for memory on the 290/290x, only for Core.
Voltage is no longer static, it changes, so offset is how you change it.
100mv max.
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 are assuming VDDCI is the memory voltage. Unwinder has said there is no memory voltage control on these cards.

Just installed the Gelid cooler, I would suggest following the pictures/instructions over at this thread- on overclock.net.
Instead of using the crappy tape adhesive for the RAM I purchased a vial of AS Thermal Adhesive and used those on the RAM and VRM2 heatsinks.
So far under furmark load I've seen a max of 72C at 74% fan, I pushed the fans to 100% and you can't even hear the difference. The quality of the parts is questionable but it did get the job done, will probably look at purchasing some upgraded fans for the heatsink in the near future.
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.
did anyone here check GPU usage in BF4 with 290/290x?
I am getting GPU usage all over the place, its never steady in BF4 for what ever reason, every second it goes up and down, the graph looks really bad, it drops from top to nearly bottom.
Using MSI Afterburner Beta 17.
ok, thanks.
What about vrm temps on load?
Its not a problem with Afterburner.
Afterburner is reporting the data the driver returns, it doesnt perform any calculations to get GPU use data.
same for mestill crashing with the new drivers still
its the drivers, see my prior post.
its been confirmed.
Its the actual divers
If the gpu usage is polled too quickly by the driver after another sensor, it returns garbage.
I assume amd will fix it at some point
VRM Temps during real-world gaming (BF4, DayZ, Arma3, etc) will reach around 62-65C MAX. Running furmark VRM1 maxes out at ~100C. VRM2 is usually lower at around 55-60C during benchmarks. I have yet to see the core drop below 940Mhz which is AWESOME, before switching to the aftermarket cooler, I'd see dips down to around 800Mhz or more.
So I'm pretty pleased with this thing, I will say though, the VRM1 temps are kinda high, I put the long VRM attachment thingy that came with the cooler on it, but noticed the mounting holes didn't perfectly line up with the board . I ended up rigging it up with some copper speakerwire threaded through the holes and clamped down then tied off. It's held on pretty sturdy but if anyone has any ideas for what i could use instead that would be great. I was going to use the narrow heatsink's that I used on VRM2 but I didn't have enough to run the length of VRM1.
its the drivers, see my prior post.
its been confirmed.
I am not sure why you didn't just use the same AS Thermal Adhesive that you said you used on the Ram and VRM2 heatsinks..If you mix it properly, and then apply it in the proper timeframe, that stuff will work wonders..I used it on my old 4850 with an Arctic Cooling S1 and it a wonderful job holding the heavy square 'sinks I used on the VRMs.
Contact AMD for support.
They may want to know that Newegg arent helping.
You know everytime I start to type a post about my frustrations and aggrevations with this card I just stop and erase it because no one really cares. AMD has my money and I can't get a refund from Newegg. XFX says they can't do anything for me, I have to wait for new drivers.
I've come to the conclusion i'll just take my $475 video card and aftermarket cooler (because they can't get that right either) investment and let it sit on my desk and use my old video card until these people figure out how to fix this POS.
I will NEVER purchase another AMD product again. I learned my lesson the hardrway about AMD processors and now I've learned the hardway about their video cards.
I tried, after being on hold for 40 minutes and no one ever answered, I again gave up on them.
