Polaris Bios Editing ( RX5xx / RX4xx ) - Page 154

post #1531 of 3453
@pok123 Your welcome. Your temps look solid. Can't wait to see the next bios results. Try DeLimited, first. Then if needed move to Cooler bios.

*Side Note*

So I have tested Tomb Raider 2013 - 4k - Ultimate - 1433Mhz - DeLimited - Runs Awesome - VRM is a bit high but stabilized and didn't budge past 87C. My max shutdown temp is 88C, so it is allowed to hit 87C at least. The deviation between the Core temperature and VRM temperature is 11C. Also max fan RPM of 3166rpm, which is pretty inaudible.

That deviation of 11C, means the VRM pad is likely 11W/m K shy of matching the core temperature at 1433Mhz. Meaning the conductivity of the pad is about to guess 3-7W/m K. Fujipoly 11w/m K would match the core temp and Fujipoly 17W/m K would exceed the core temp by 5C or greater at this clock. I have yet to test the 11W/m K fujipoly which I have, since I want to use Thermeez Thermal Putty first. So basically with the stock pad to achieve an 11C reduction on VRM temperature, I would need to set fan rpm 15.79% higher. Which would be 3667rpm which is too loud. So it will need better material or Thermeez if it ends up working as well as I expect it to.

Thermeez is Ceramic Thermal Putty. Basically ceramic curing putty, that cures as it heats up and the hotter it gets the more thermally conductive it becomes. Based on VRM application of Arctic Silver Ceramique 2 on VRM, it should perform equal if not better than Fujipoly 17w/m K on a budget. It also should not be as messy as Acrtic Silver Ceramique 2, as it hardens and doesn't make a stick mess if applied carefully. It should also last a very very long time for thermal applications. Right now I'm using Arctic Silver Ceramique 2 on the core, super thin layer has conductivity immeasurable at this thickness. Which would also apply to the Thermeez at super thin applications.

This card is a beast, no reviewers give it the credit it holds (Teasing nudge nudge thumb.gifwink.gif ). It's capable of hanging with the highest of end GPU's with no power limit. AMD may thoughtfully consider just setting the Power Limits to 999 from the factory and dial in the Targets so it doesn't overheat. Which more appropriately controls power output, while giving no lag-outs and ultra high speed performance. Unlike stock which is an utter slideshow at 4k ultimate. I hope I'm not too forward to say so, but I'm trying to help. haha wink.gif

@chris89

delimited is the first bios you gave me right? 1000mhz clock 1797mhz mem?
post #1533 of 3453
@pok123 I sent 2 bios, which in the title says "DeLimited". thumb.gif

post #1534 of 3453
@chris89 lol i see it now thanks, will try this weekend and report back

actually, I see the gpu is overclocked to 1333mhz.. i'm not looking to overclock, i think the card was already OC at 1230mhz by default... can I use something that is strictly power saver?

@pok123 Cool dude, hear ya go. DeLimited 1Ghz Core 1.5Ghz Memory. This bios should be a top performer on a minimum power budget.

*Side Note*

I found out the absolute most essential part of achieving more performance and consistency is to consider this. Basically the fan controller is hard coded to slowly increase rpm, which is amazing. I'm finding more out about this card with all my trial and error. It all has to do with the "Fan Sensitivity". I found that the stock sensitivity was 4836 value which means the fan is going to take For-Ev-Er to spin up. I tested values in between 0 and 8888 and it always takes For-Ev-Er to spin up with these values. I then finally came along value 0, which solved 99.9% of the issues with any value above 0 from what I had been seeing. Which now actually spins up but takes less time than higher values took a mid 70C temperature to actually begin to increase. It's all about how many RPM per second will it rise. So value 0 gave about 100 RPM per second and did fairly well. However I then tried negative value, which defaults to the key to success value of 65333. Not to mention my max RPM was set to 3333rpm, which yielded the below results. It performs very consistently now every single time and WOW the 4k performance smokes everything i ever tested before.

Now the card is on the top of it's game at Sensitivity 65333. That's where it's-all-at. This card literally blew the doors off my DeLimted Maxidy-Max clocked 390X at 80GPixel/ 220 GTexel/ 450GB/s. I also found much higher sensitivity helps even more up to and beyond 33333.

Not to mention I broke down the card again and replaced the Bergquist material with Fujipoly 11w/m K material. Which also resulted in impressive gains, clearly far superior to Bergquist in the high speed range. So in conclusion, I can dial in a super speed bios for the RX 480 near or at stock voltage. I found I resulted in a black screen above 1466mhz booting to windows, along with any voltage higher than 1234mv. So it's possible now I could see even higher numbers than this. Also found 2266Mhz memory clock at 1000mv stock timings yields no where near the level of errors the 390x through out and gives 290GB/s.







Comparison on AIDA64 GPGPU Test : RX 480 numbers could be higher if sped up the fan speed. You can see how it gets faster over time from left to right. After the end of the 1st test, the fan had just begun to spin up. Which is right when I started test 2,3 which fan was well sped up through. Also RX 480 is in NUMA mode. Which also is slower than SMP with it's striking performance increases on frames per second Julia & Mandrel.



SMP Mode with 33333 Sensitivty 3367rpm max. It took 2 1/2 minutes to get spun up. Which it doesn't perform until then. I just open GPUz Render Test and wait 2 1/2 minutes for the fan to spin up and then hit up the benchmarks as quickly as I can. Since as you can see, that middle benchmark was 10 seconds of fiddling between starting it again... The fan began to spin down at that point. Which it starts to spin back up after beginning again, however it's the time delay on spin up that dictates it's performance. When fan is static spun up, performance is very high and consistent.

Which is also showing that ideal max clock is 1433Mhz at 1233mv. No higher really. Maybe a couple Mhz and 1-2 Millivolts before no-load OS black screen upon boot. Although it can boot to windows at 1466Mhz at 1233 or 1234mv no problem, except benchmarks aren't stable. Only reason for instability at 1466Mhz is the fan speed spin-up delay. If it were able to spin up quickly, it could maintain stability.

I have an xfx rs 480 8gb, stock 1288/1.15v and 2000mhz. Crap asic 65%... Figures
Recently, Even on stock bios stock settings, I was occasionally getting bsod. Not even full load, using vsync 60fps and 65C GPU temp! So it's not like occt level of stress! Also occasional coil whine on high load games like deus ex.. I also tried my other 600w psu, to eliminate that issue. Even tried with stock cpu/ram speeds.

So I downclocked to 1270, no problems for days. This card was failing occt at stock clocks when i first got it, but no bsod then in games. Now it happens at xfx 1288 stock. Occt doesn't bsod but will report errors at some time or crash the driver which win 10 reloads ok. Only the games can randomly bsod after some time, hour or so of play.
I got rma approved but xfx sucks, no advance rma, no shipping label (my gigabyte 7950 was much better rma policy). So I don't know, a dud from the start I think but is it worth the lottery of shipping cost, time for ship +then testing it only for them to maybe never get bsod or get another crap asic card?

Honestly, shouldn't 480 be able to do 1288 stock at the stock 1.15v? I see people getting that at lower voltages!

@robnitro Which card are you using? Have you monitored your VRM temperature with HWInfo v546? My ASIC is only 70% on reference RX 480 8GB from visiontek. I'm hitting 1407Mhz on stock voltage. Zero crashes of any kinda, only when testing new bios will it fail to load into the OS. So I would say your VRM is overheating and your fan isn't kicking in enough. Send me you BIOS and I'll take a look bro and dial it in. thumb.gif

It's xfx rx480 rs, the vrm temps don't show in the utilities but I don't it's vrm because happens even when load is very little like 50w. This card can push 150w no problem in occt at 75C stable with fans maxed... Only if I set clock to 1270 and below, or 1280 if I run 1.175v.

I think my chip is just a dud. Also heaven will crash or bsod at stock 1288/1.15v and that uses only about 120w...

I went back to stock bios just to make sure it wasn't the memory straps.

Seeing how the stock bios stock clocks with low loads and temps fails randomly, i think i should just do the rma...

I downclocked the 1250MHz GPU clock to the reference spec of 1210MHz across all GPU states and set the power limit to the highest Wattman would allow me (25%) and I still get black screens. Is there anything else I should be doing (memory clock of 1650MHz is stock afaik)?

Edit: The default voltage for 1210MHz was 1031mV, I previously had each state set to 1210MHz with voltage control on auto. I will try setting each state to 1031mV and see if that helps.
