Sapphire RX 470 8GB E388 BIOS

[nfinitefx]

Hi,

I am looking for the VBios for my Sapphire RX 470 8GB with Micron memory. I have tried a lot of the VBios (verified and unverified) but they are all not working. Yes I have tried all 4 BIOS switches and all of them are messed up. All of the BIOS I've flashed (and successfully loads Windows) shows 0/0 frequency on GPU-Z. The rest, will not load Windows and shows black screen instead. I've tried I think almost ALL of the verified and unverified E353 VBios since E353 supposedly should be similar to E388.

Sapphire customer tech are also having trouble providing the BIOS. They've given me 2 VBios for E353 but they are for Polaris 20 and they didn't work. I'm still trying to get more VBios from them.

The card's sticker seems to be incorrect (PN 299-TE353-430SA, SKU 11256-65). After scouring the net I found the probable correct part number should be 299-WE388-000SA with a SKU # 11256-57.

Here are some sites with photos of the PCB which matches mine.

All those have the exact PCB # as mine 236-DE388-0C0 and P010-0276-00 and has a E388 sticker on the PCI-E connector on the bottom along with a QR Code for a number plus a part number EWE388000SA. The attached photos are photos from my card.

To sum it up here is the confirmed information on my card:
- Micron 8GB
- PCB # 236-DE388-0C0 and P010-0276-00
- E388 and B0350 Stickers on the PCI-E Connector
- QR Code for a number plus a part number EWE3888000SA
- DVI-D Only Output

Probable information:
- PN 299-WE388-000SA
- SKU # 11256-57

It would be great if I could get some help from the forum regarding this. Thank you so much!

Might be worth doing a search through the forum here for the BIOSs as I remember another 4 Bios mining card with the same issue not too long ago, not more than a few months anyway.

Ok so I've searched through 32 pages of the AMD/ATI threads and only found 1 thread with the 4 BIOS. I tried them and they didn't work.

I also asked the seller where I got the card from and they have an old GPU-Z screenshot of the card but I'm doubtful it's the correct one since it's for E347 card and Samsung memory and 1206/2000 MHz frequency. I have tried a few of the similar BIOS but they're not working so far. Will try some more. Thank you.

This should be your card, not that it helps with a Bios as it only identifies the GPU.

I'm not sure about this since my GPU Variant is 215-0876406.

Anyways, I have just finished flashing ALL available VBios for RX 470 8GB (all memory brands). I counted 89. None of them works. There are varying results :

- Best case: Windows fully loads, 0/0 GPU and Memory clock. Unknown fill rate and bandwidth and shader. (Like attached).
- Worst case: Windows crashes during boot-up. I would have to go into safe mode and use DDU. Then Windows load again and I reflash with another VBios.
- Windows partially loads, but crashes soon after. Then I would switch to an alternative BIOS and reflash.

I didn't use DAG patcher since it causes some of the crashes. I'm not sure what else can be done next. Sapphire still cannot provide the correct BIOS either since they need one of the stock BIOS sent to them so they can send the original BIOS.
