WattTool: A simple tool that combines overclocking with VRM monitoring/tweaking for RX 400 series - Page 5

post #41 of 380
BromoL,
could you please tell me, what is the adress of voltage offset in BIOS?
My Sapphire Nitro rx470 has default offset +25mV, but I would like to flash some negative offset in bios...

the Volage offset in the BIOS would be very interesting smile.gif

No I haven't. My offset raises my p0 voltage to 887mv. I was looking for a way to run 800mv on idle but keep my offset. Or have profiles so I can remove my offset/overclock when I'm not gaming or benching and run stock on idle for other tasks. Right now., I just reset in wattman with wottmon still open saving my values. Then when I go back to gaming I reapply settings in wattmon. But that leaves me having to re-enter my overclock on boot if I don't want to boot with 887mv going to my video card for p0 initialization on driver load. I occasionally get a little pink flash on driver initialization that may be related to the extra voltage.

I tried the air unlocked bios and asus gpu tweak. It was terrible. I couldn't hit the same overclock and a failed overclock didn't reset and was persistent into the next boot. The failed overclock was lower than what I can do with an an offset so I I don't know. Maybe the unlocked air bios loads different memory timings.

So if you can get me to stock on p0 I'd be very grateful. Thanks for your help.

My tool has absolutely nothing to do with bios editing. I assume that this information is available in the polaris bios modification thread.

OK, so i will disable the P0 fields.

I will also add buttons for stock settings (very easy to do). Profile support of some kind is planned, but i have no timeframe for this. My time on this tool is very limited and at some point i might leave it as it is. Feedback is also kind of scarce (this thread is the only communication channel i use). Several people asked for multi-gpu support, but so far there is only one positive confirmation. Adding proper RX 460 support will be impossible without someone testing it.

The pink flash was unrelated to my offset. It happens on stock too. I think it's just a slightly messed up card. from day one on the reference cooler and at reference clocks I've gotten this




In game for JC3 is fine. All other games are fine except some annoying artifacts in ROTR. I'm waiting to hear back from sapphire about RMA. Probably the pink flash is related to whatever my memory controller is doing to mess up without throwing errors and I'm over-reacting about the potential for problems with running too hot on voltage on p0.

Anyone else have a problem with multiple GPUs? When I try to select anything other than the first one that comes up, I get a popup stating the GPU I selected, but then everything just closes when I click ok. Also, would there be a way to apply the changes to all GPUs rather than having to select each individually? Thanks!

I reproduced and fixed this bug. The buffer holding the current selection was overwritten by the asynchronous monitoring function while the MessageBox was displayed. Stupid me! The MessageBox was removed and the buffer is now exclusive.

As per request i extended the voltage offset range to +-300mV. The most important change was made possible by @W1zzard (Thanks again). I2C access is now synchronized with other popular tools via a global mutex. For example, if you start up HWiNFO while monitoring VRM status with my tool, you will get some readings of "NA" instead of a possible system crash.

I also made a namechange because the original name is already used for a Remote Energy Monitoring And Control Platform (hardware and software). I dont like the new name but i dont care.

Reporting that multi-gpu to reference RX480 is working great! Good detection on both cards! Thank you!

How do I disable power shift from slot to 6-pin in the program?

Select "None" below phase gain. The first three phases are powered from the 6-pin, the remaining three from the slot. AMD's fix for powergate was to increase the load on the first three phases leading to a 56% vs. 44% split. This can be undone by selecting "None". The VRM phases operate more efficiently when loaded equally. TomsHardware measured 3W increased power draw after the fix.

Thank you for the answer, and thank you again for your work! This is a great app, simple and reliable! smile.gif
