Thanks, it's nice to see a tool like that, simple functional unlike the AMD Wattman eye candy crashing "thingy".

For those putting the 1750 timings onto the 2000 timings a word of caution. after trying my normal overclock with the 1750 timings for 1 short failed run of valley, my video ram degraded. Now back on the 2000 stock timings my max overclock is 25mhz lower for memory. Just a word of caution. To make sure the settings weren't being carried over after the re-flash I did a ddu and reapplied the patched atikmdag.sys and re test signed it. So it really did degrade I guess.

Are you sure your VBIOS got set to 2000 timings? I saw the pictures posted in another thread and it looks same as for 1750. It's strange that VRAM would do that.
post #525 of 4668
Here. I took another screenshot with the end of the timings scrolled over. the beginning of all the sequences are the same so it's easier to look at the end.

I haven't re-dumped my bios and made sure my bios matches the custom rom file, but flashing showed no errors. 2220 was my old max overclock. 2205 was for safety. I have to run 2195 now.



edit: for sanity's sake I should note that I did try the stock bios as well. It seems degraded. This card was already waiting for a rma due to memory issues anyway. Waiting to hear back from Sapphire It's not urgent though. Replacing is a pain as my loop doesn't have a drain. Takes a couple of hours to get it all taken apart safely without dripping on anything and all but 2 of my games are fine. All are playable. . Those issues have occurred since the card was unmodded on the stock cooler and brand new and not related to this issue. But maybe it's why it degraded so quickly.

edit2: dump from current bios 2000 timings: 777000000000000022CC1C0031F67E57F05711183FCFB60D006C070124081420FA8900A0030000001E123A46DB354019
the current bios was from a re-dump of the card not my file.

dump from stock bios 2000 timings:


777000000000000022CC1C0031F67E57F05711183FCFB60D006C070124081420FA8900A0030000001E123A46DB354019

they are identical. Just making sure.

Hello!

I finally got my Sapphire RX 480 Nitro 4GB. I have those 4GB stickers on packaging and when I remove them there is 8 GB text under those.


Is this card flashable to 8GB? And is it safe to flash considering it has dual bios? I never have flashed a GPU so far.

I also bought my Sapphire RX 480 Nitro + 4GB OC. I have those 4GB stickers on packaging and when I remove them there is 8 GB text under those.

I also want to know is this card flashable to 8GB?

And is there a link with guide, utility for flashing and BIOS formware file?

It is not.Only the reference RX 480 4GB had 8GB. The Sapphire RX 480 Nitro+ 4GB OC uses exactly 4GB memory from Hynix. The stickers are a cost saving measure. The extra 4GB on the reference model were a marketing decision.

I tryed Sapphire Nitro RX470 4GB, it has Hynix H5GC4H24AJR memory chips, they are 4 Gbit, so there is nothing to unlock.
Sapphire Nitro RX470 8GB has different memory chips - Samsung K4G80325FB, they are 8 Gbit, like on reference boards.
Some other 8GB cards have Micron memory (like MSI RX470 GAMING 8G).

What are the chances that the 1750 timings I copied onto the 2000 timings stayed even though I've since flashed it twice and a bios dump shows the correct 2000 timings? I'm getting artifacts like crazy in ROTR dx12 and lockups.. I had to go to 2000 mhz dx11 to play. I did send an RMA request to Sapphire last Friday for the day one issues I've had since the late June release, but they haven't gotten back to me. I emailed them again yesterday and they still haven't gotten back to me, so I'm not really happy with Sapphire support right now. Their online support told me to email tech support for rma. I did, twice now, and then they have not yet responded.

It's just such a coincidence that the problems would get so much worse right after the failed bios experiment. It flashes white stars and black missing parts of the screen like a failed memory overclock. I drop the frequency and it works for a bit then gets bad again after ten minutes or so, so I drop the frequency further. HWiNFO isn't showing memory errors so maybe the problem is in the memory controller. I was getting memory errors at much lower frequencies than before in The Evil Within. For some reason that undemanding game shows memory errors at lower clock rates than any of my other games, so I use it to test memory over-clocks. But I have to go way lower than what's stable in Evil just to keep from locking up in ROTR now. I suppose I could flash the card with the stock bios one more time and ddu one more time. But if Sapphire might not honor the warranty anyway since I've got an aftermarket water block on there. I have the original cooler and stuff to put back on for the RMA.

The original problem I was getting an RMA for was due to graphics corruption in 2 games ROTR and the title screen of JustCause3. I'd get odd pixelation at the edges of water in ROTR and blocky distortion if I enabled SSAA HBAO+ and DX12 at the same time. I get the same distortion in the T-REX benchmark in foliage. Both games were purchased with the card and had problems before I went under water, but who knows if they'll honor the warranty as they wont email me back to say one way or the other. I'm about to just purchase a replacement.

Any ideas?
