Polaris Bios Editing ( RX5xx / RX4xx ) - Page 190

post #1891 of 3471
I do not have any framerate issues and i need the best performance/power ratio which would not be possible with 1000mhz Core clock. Yes, the power draw will be much less but i need a higher performance.
post #1892 of 3471
Have you tried 1000Mhz? That's 32 Billion Pixel's consistently, remember... not slow by any means.

Up to 1407Mhz, only 13 Billion Pixel's... which is only 40% yet cannot be sustained at that 40%... So yeah just a lyk haha I tried it very surprising performance to power.

For the Rx 480 to do 2Ghz, just needs a reference heatsink of twice the length and a larger fan... sounds simple...it probably is haha

Totally respect you ,but i need this performance and going back to 1000mhz is pointless. I do not care about the temperatures as long as the card is not throttling- i do not care about the card life and etc, i have not married her and i need to use her at it`s max performance. I am using 2k resolution and need the squeeze the performance without increasing the temps too much.

Hahah I get ya 100% man... Try out those settings I posted on the previous page... Add some RPM if needed? Probably will... I just hit VRM 86C but it was 35fps consistent vs 25-45fps. Dial back ram to what works for you... I'll update as I find out what works best... I suppose I could deal with 86C VRM with consistent 35fps city fps fallout 4 at 5k... 5120x2880.

Thanks, but can`t go higher than current RPM limit of 2300rpm - any higher it is freaking terribly loud. Now VRM`s at 90 is in FireStrike where the GPU load is much higher, normal ingame VRM`s Temp is around 80-83.
I am planning to replace the stock cooling with Accelero Mono Plus to get some lower temps and much less noise. Accelero Mono Plus is almost the same heatspreaders area, but it has 5 heatpipes compared to the stock two heatpipes.

Right on try my settings with your desired settings and see if it help as it did for me quite big time I would say.

Btw - funny about heat pipes? My reference has non and does great... I'm not so sure heat pipes are all too spectacular... compensate for mass and density for a heat pipe... haha works well in a laptop but even they could be better.. haha Just thoughts bro I hope u line it up the way you like.

Which of your advised settings do you like me to try, can you specify them please ?

P.S The number of heatpipes dictates how fast the heat will be transferred to the aluminum heatspreaders. From there it all depends on the heatspreader size, mass and fan CFM.

Mono is a good choice, this card should be sold with this cooler from the beginning. Overclocking with Ref cooler is pointless. Usually ppl undervolt their cards with Ref cooler. With mono you should reach 1400-1450 MHz, depending of your chip, easily with reasonable noice without any throttling which is the most important.

Nvidia's blowers works great, unfortunately AMD's not.

I need a help from the super experts in the forum, thanks in advance.
This is the table VOI from the bios of my card (RX 480 Nitro + OC 8GB):



Unfortunately, I have many questions:

1) I have not retrieved any information on the registers 14, 61, 62 and 69 of IR3567B controller.
2) the register 33 is set to h72 ie binary 01110010, bits [7:5] is 011 ie x3 = 325mV (OVP threshold), bits [4:0] is 10010 ie x18*2A = 36A (Loop 1 per-phase OCP threshold) I know my card uses 5 phases so 36A*5= 180A. If my understanding is correct what these values? (maybe 180A is max TDC?? I have no idea about 325mV!!!)
3) the register 24 is Loadline slope Loop 1, (set to 0.7mΩ) What if you change this value?
Actually fully I understand just 8D register (Voltage offset Loop 1) set to +25mV for all DPM.

Sorry for my bad English.

Greetings.

I can't confirm this, timings available on first post of this thread are as stable as stock ones. Especially Uber V2.1 of course for Samsung mems. I use them and can't complain for stabilty. Replacing timings may be very useful if your mems dont like to overclock.

VRM temp isn't crucial, stay below 115 C degrees and you will be fine. Core temp is very vital, lower temps may extend overclocking stabilty.
hello Na1l,

I have OCed my memory to 2250Mhz as mentioned earlier and without touching its voltage but would like to push the timings more extreme.how to check which memory brand my card is using? are the timings in the OP only valid for Samsung?I believe Hynix is the other memory maker AMD is using on RX480, would that timings work on my card if so?
