Please need assistance with my RX 580 card. I please need someone to help me to add the correct memory timings. I dont have the time to mod this card. There is a user on here @ket That knows these cards very well but not sure how to get hold of him as i am new. I mainly use this card for gaming but as i understand it, this card can push more than factory with heat in mind. All help will be greatly appreciated.

Hello,
I have much expirience with the RX580, if you can tell me which card it is exactly I can make a custom bios for you, or guide you into making you’re own vbios. I with my XFX RX580 GTS XXX was pushing WR on air cooling. But something went wrong with the card and it doesn’t boot as it use to, and also I lost the heatsink screws…
1600mhz core
2430mhz mem
1000w vbios
My card is a RX580 Nitro 8gb and is using Samsung memory. The Bios on Tech powerup does work 100% and can be used to mod the bios . The thing is that i really would like to push the card to perform it’s best . I dont really care for to much OC but aleast have better Fine tuning maybe in the Bios aswell as Memory timing. Currently it runs well on 1400mhz and 2000mhz memory. Can you assist in fine tuning this bios inlcuding the fan curve , volts etc?
Thanks for the reply , i have been following your post about this cards but obviously its not my cup of tee . I will send you one. I can’t attach due to new user.
@Nem I tidied things up in the vBIOS generally speaking once I know how this does further refinements can be made. This vBIOS isn’t really about performance at this stage its about finding the cards sweet spot between power consumption and maximum frequency.

@Nem vBIOS is good to go, as I said its a baseline to establish the best power to performance ratio for your particular GPU, typically on Sapphire cards the GPU is pushed to the bleeding edge out of the box which results in copious amounts of heat, noise, and power draw so normally its best to dial the GPU clock back a bit, lose a negligible amount of performance then pull things up with advanced memory timing optimisations. Best of both worlds. Knowing what the ASIC quality is for your card would help, you can get that with GPU-Z. Currently maximum GPU clock is rounded down to 1.4GHz @ 1.1v, the voltage should be enough but it will depend on your specific GPU its not really ideal running more than 1.1v to the GPU ordinarily. In terms of testing the Final Fantasy XV benchmark is ideal, set it loop and to maximum settings, disable the nvidia stuff as it doesn’t play nice on AMD cards then just let it run for at least an hour to test the new lower voltages under load.
I will do so . I do aleast have basic knowledge of testing and will check for any heat spikes and errors. I will also use the Bench you gave me.
The Asic Is a out 78% if i last checked for this card. I also like to play red dead 2 for fun and the game will also be a nice bench. Will let you know how things are going tomorrow. THANKS a mil.
@Nem An ASIC of 78% is pretty high, I definitely wouldn’t recommend more than 1.1v on the core. In simple terms the higher the ASIC the lower the voltage is required to achieve maximum clocks.
I did flash and bench the vbios. It is stable and temps runs max about 70 tot 72c.
No issues whilst gaming and no Mem erros in HWInfo.
What can we do to push the performance further? Especially memory maybe? The Core Clock seems that 1400mhz is the sweet spot. What i want to ask is can you mod the Mem as this is you speciality😀
@Nem One thing at a time to make sure everything plays nicely. With a high ASIC core voltage should be able to come down some more, for an RX580 70-72c is decent but getting it a bit lower would be ideal, GDDR gets VERY hot so lower core temp = memory will stay cooler too as the surface area is shared on Sapphire 580 cards. If you haven’t done it already with the age these cards are now replacing the thermal paste and cleaning the heatsink and fans out would be a very good idea. Attached vBIOS makes a tweak to voltage under load, should be high enough to keep the current core clocks stable.
There is a Shop that service cards here. Will do that this weekend. In the meantime i will flash the attached bios tonight again and run the test once more.
Side note : it also depends when the Framerate of games is dropped like from 60fps to 30fps the temp drops obviously to 55c max with Higher Graphic settings. The next example is when i Run a demanding game like Red dead redemption 2 with ultra/high mixed optimized settings on 60fps i get a stable 60fps with a slight drop to 55fps now and then , that is where i hope that you can fix this memory timings that you are very good at. I truly believe that it will make a steady 60fps . I dont expect the card to run higher and i am happy to play on 60fps most games anyway. So on 60fps = 72c max and on 30fps = 55c max with the fan curve in the bios. I will let you know tonight how things are going.
Also i know that the RX 580 is old and date back to 2017 and is not that much of a high end card but the Card really does well with it’s age and that is why i looked you up for this as i know you are very good to optimize these cards and i like to run my system with optimized mods . Aleast you get your moneys worth.
NB:After the voltage drop from yesterdays Vbios you sent temps actually went down from 78-80c to 70c so there is a good drop on heat here . It usally stays about 72c max but with spikes to 78c on some parts of the game . Now it is steady 70 -72c . Lets see if we can gain more with the update vbios you sent now.
No extra heat , dropped down from 72c tot mostly stable 66c . So from stock to the latest vbios you sent heat went down to lets day 14c max. The rest all stable including no memory errors and no crashes. So everything Solid so Far.
@Nem Alright, next step is to use wattman to manually OC the GPU and memory, doing one at a time. Increase core frequency in 25MHz steps to see how far the core can go before instability/crashing sets in, I’d wager you won’t get much further than 1450-75MHz but thats fine Polaris isn’t frequency starved we are just checking how much headroom you have here to ensure even under demanding scenarios you won’t encounter stability issues. Once you have identified max core frequency reset wattman and start OCing the memory, see how high that will go until HWinfo logs EDCs or you see visual artifacting. If its anything like the cards with Samsung memory I had you won’t get far, 2050MHz at most. Once I know the results of this I can apply the last few changes.
Ok i can actually give you the results , i went a step further and did just as you asked above yesterday after the vbios was stable on undervolt. The Clock can go to 1450mhz but then the heat spikes to 80c so stable with heat is a about 1400mhz. The Memory frequency reaches 2045mhz with no errors and temps are good 66c about. But if i increase the memory to lets say up to 2150mhz the mem test in you flash pack that you uploaded on another Post i get about 2000mhz = 203gb transfer rate and on 2150 i get 226gb transfer rate bit then the errors arise to 50+. Now what is strange is that from 2050mhz up the errors start but no heat increase and the actual benches or game test has no artifacts. I not pro here and obviously you will know this but it seems that the memory do or can run stable up to maybe 2150mhz with your mod straps . As i read you posts is like as the memory goes up the timings gets looser. So here is the final result.
Core : 1400 = stable @66c
Core : 1450 = stable @ 80c High temps.
Mem Freq : 2000 = stable @ 66c low transfer rate.
Mem Freq : 2050 - 2150 stable @ 66c high transfer rate but with errors. But no artifacts.
The question is can you do anything about memory because it actually lifts up the transfer rate really good at 2150 mhz? About 226gb transfer speed or rate.
