Is the mV memory value bugged? I modded my bios to use 1150 mV (testing timings) when it hits 2000 Mhz but watttool shows 1000 mV (stock value).
I tried some timings that weren't stable (few EDC errors) at 1000mV, no they are perfectly stable with 0 errorrs... It possible that the real value is 1150 but Watt Man and Watt Tool shows me 1000 mV just because it should be the default value? Can some one confirm/test this?
I'm modding the bios of my RX 480 Nitro+ OC, I'm quite unlucky (80% ASIC but I cant't OC s***) my VRAM can reach 2220 MHz but everything past 2100 just spawns EDC Errors (a ~5k at 2150, ~2kk at 2220, crash past 2220). I still have to touch Core frequency and voltage, I want to tweak my VRAM first. I decided to improve timings, at 2100 with the 1750 strap copied onto the 2000 strap i just need to raise the memory voltage to 1025 mV to be perfectly stable (if not I get like 10 errors, nothing to be worried about but I want to be safe). My current plan is to raise the voltage to 1150 mV (the max safe mem voltage) find the tightest stable timings (following this method: https://youtu.be/TR25v-jvWao
, starting from 1750 timings as base) and later, find out if I can lower the voltage a bit (I hope 10/20 mV).
I modded my bios like this:
- TDP and Max Powerlimit = 225
- TDC = 190
- Copied 1750 timings to 2000 strap
- Set 1150 mV next to 2000 MHz memory frequency
I didn't change the frequency to 2100 and left it at stock 2000, so I'm sure that the card boot and I can set it manually by (when I find the best timings I'll set 2100 inside the bios).
Btw, the real question is, now the memory is perfectly stable but WattMan and WattTool still shows me 1000mV, since the m is stable should I assume that the 1150mV is correctly applied but the oc tools shows me 1000mV just because it should be the default value? Can someone try/confirm this thing? Is 1150 the max safe voltage for memory controller? Is 1.300v the max safe voltage for core (future plans)? My card is cooled by an Arctic Accelero Hybrid III 120 + Custom Unified VRAM+VRM+PCB Heatsink + Back Heatsink (pictures will come).Edited by Vento041 - 11/21/16 at 2:40am
