exactly. I wish there was better drivers for this card. I compensate with lower power and higher clocks. Much more than I could squeeze out with afterburner and much much more responsive and cooler.

I just want that shiny new 1080...lol

I'm a happy camper. 1175 on core of 1356mv, max temps when gaming was 65-67c. Furrymark takes it to 73c in a bench run. No artifacting at all. Will slowly lower volts to check stability.

Where are you reading your output from?

My max temp overwatch on ultra is 60c with my AIO, I want to go lower!!!!!!!!

888mv is his actual setting he uses in his BIOS. When you use software like MSI AB you are applying an offset to whatever your cards stock voltages are.

You can view your stock voltage in wattman by enabling the ability to adjust them with the slider button.

You could then potentially adjust them individually in wattman instead of using the offset in your other software, but wattman and other 3rd party software dont play well together, and for many cards wattman is the inferior utility. Seems the 400 and 500 series of cards have much better support and many tools available compared to older models for no obvious reasoning.

If you are using the offest in MSI AB, all you have to do is look at your stock voltage in wattman and +/- the offset value you use to know your new voltage. That value should be very similar to what you read with a real time voltage tracker like Hwinfo or MSI AB utility.

@RaFDX It would be kinda awesome to run at below 50C load... Would need to remain stock or just 1Ghz on DeLimited power limit 65288 core voltage max 1.25v. On 888mv memory at 1250mhz.

You could game at 48-49C...? 1000mhz core 64gpixel 160gtexel r9 390... thats a ton of performance the difference is minimal and cool running is what feels good right?

lmk I can try and line you up a cooler bios.

Chris...that is exactly what i am trying to run via software. I am working on getting it done via BIOS, but until i have more time to tinker i will use what i have now via AB.

It runs much cooler and quieter than stock by far even with my software undervolt. A BIOS fix would be tits though. I will hit you up with a PM when i am ready but thats exactly what i want to try to start with.

Just need a screw driver. This is what I used to guide me through my first thermal reapply, before I went AIO. There are two cables the connect the radiator to the card, so be careful :-)

so it looks like i'm running at 200-300mV more than you guys. I'd like to get equal performance at lower mV

There are multiple voltage controls on a card. Afterburner doesnt always allow you to modify them all. In this case it looks like you have gpu core voltage control...but i dont see memory control ot auxiliary control. The 888mv that keeps being sited is chris's voltage for memory when clocked around 1250mhz speed. I dont believe it is the core voltage on the gpu, which will greatly depend on your clockspeed, powerdelivery, and the quality of the silicon you won in the gpu lottery.

Cards of differing quality will hit different clocks at different voltages. There are only rough guidelines for what voltage is needed at what clocks that may need to be fine tuned on an individual basis.

awesome thanks for the clarification
post #11230 of 11376
I find that with all the 290X & 390X at least these need mathematically 10% more core voltage per clock... 176 TMU 290X/ 390X vs 160 TMU 290/ 390 is 10%.

So for 290X/ 390X 1080Mhz on 65288 (1.25v max but will only go to 1.25v under 4k or high stress), 1133Mhz 1333mv, 1166Mhz 1366mv, 1177Mhz 1377mv, 1188Mhz 1388mv, 1200Mhz 1400mv, 1250Mhz if thermals allow on VRM 1 Core of between 1415mv-1449mv. With artifacts on the lower end of that scale, without on higher end with likeliness of black-screen. Need more rpm soon at lower Core Temperature to keep VRM in line at 1250Mhz. 1449mv is too hot on most all cards even water but is what is needed for real 24/7 stability artifact free 1250Mhz core on all cards. Hot VRM, Hot Card. Only 1425mv is max on most all cards for 1250Mhz and gives awesome results.

For the 290/ 390 maybe 1100Mhz on 65288, 1133 let's just call it 1266mv, 1166mhz 1333mv, 1177mhz 1355mv, 1188mhz 1366mv, 1200mhz 1388mv. Basically... These voltages are not based on "What Works" but that extra bit of voltage required for those rare later on crashes or instability... You need more than "What Works" for continuous stability to have that extra voltage headroom when it is needed, which it will require over the long haul. I tested lower voltage, many voltages lower work sure but are not 100% stable in the long term. That's why I defined the true upper-end of real stable voltages here. Rather than the minimum possible that just works.

290/ 390 can do same clock as 290X/ 390X at less voltage because of 10% less TMU Count.

Gotta Watch VRM 1 Core and have a fan profile that kicks in sooner at a lower temperature at higher RPM to hold cool temps.
