Sounds like it's for the EVGA SC, which is not a FE but uses a FE PCB.

Also, my 3DMark Time Spy score went up from 6987 (stock STRIX bios) to 7576 after simply flashing the EVGA SC bios. Clocks are exactly the same but I noticed the EVGA cards are currently leading in the 3DMark scores so I wanted to give it a try, and it worked.

ROG Strix (2,101 MHz / 1,377 MHz)
Score : 6987
Graphics Score : 7260

EVGA SC (2,101 MHz / 1,377 MHz)
Score : 7576
Graphics Score : 7993
http://www.3dmark.com/spy/71580

Card gets about 5 degrees hotter with the EVGA SC bios.

Interesting

So you flashed an EVGA sc bios onto a Strix same clocks but getting higher scores

Are you getting more volts and higher power target then with the EVGA bios

Here's my 2cents.gif

I feel I need to throw out the caution flag here... just in case there are some that do not understand the risks here. We don't want to make it sound like any BIOS can be flashed to any GPU, no restrictions.. That's NOT the case.



Right now 10x0's are new and there's a good chance they are all using the same GDDRX memory brand/model#. This changes a LOT as time passes. You'll end up with Samsung, Hynix, Elpida, etc. eventually.

All REFERENCE GPUs are required by NVIDIA to follow an exact PCB design, layout, power and voltage delivery and cooler used. The only thing that can be changed is the default clock speed basically (SC versions). This means that since all REFERENCE GPUs are essentially identical in every way all the BIOS' released by different vendors ASUS, EVGA, GIGABYTE, etc.. then all of those BIOS' are usually 100% interchangeable.

Note: If the GPU brand of memory changes during an extended production there's ALWAYS a new BIOS to accommodate that change (because when you run out of Samsung you might need to use Hynix, or whoever won the bid...). There are times when a BIOS was programming the timing and memory voltage for "A" brand and if that BIOS is flashed to another GPU with a different memory brand, it's applying those voltages/timings to "B" brand. I know for sure that each time a new memory type is used on Gigabyte G1's they release a new BIOS for it. There's NOTHING else different it's the same GPU, same model number just a different "revision" with a different BIOS just for the memory change.

Things you should be aware of if you are not.. you don't want to just flash "any random BIOS" you find here or anywhere else.




Now... let's talk about CUSTOM PCB designs. These custom designs as you know are MUCH different from reference. They have more power phases, different voltage controllers, better quality components, more power delivery, the list goes on. The BIOS' for these custom cards are definitely customized for the specific vendor part. I can't say precisely what is changed but I know for sure the BIOS is specific to that GPU. Flashing a Gigabyte 980Ti xtreme BIOS to a Gigabyte 980Ti G1 would most likely brick the GPU...

We need to understand that there is significantly increased risk here when flashing a CUSTOM PCB BIOS from VENDOR A to a CUSTOM PCB from VENDOR B. You CAN and sometimes WILL brick your GPU.

This very much applies to the 10x0 series as well. As I said, we're limiting these issues right now because the cards have all just been released and there's much more common ground...

Just use caution and ask before you flash if you're not certain. I don't want to see anyone brick their GPU...

I've flashed a modded 970 g1 bios into my 970 windforce and it worked just fine. Did the same flashing a zotac 980ti amp! extreme bios into my 980ti omega. It didn't worked as good so after a lot of tweaking I've used a modded 980ti g1 bios on that zotac card, which improved it immensely.

Right now with my 1070 g1 I've tested the 1070SC and a few MSI but found little to no improvement, but nothing blew up. I really wanna test zotac and strix but I'm still trying to get a hold of those.

So on my personal experience, as long as it's the same chip and the same memory brand, it's fine. If your memory chips are from samsung and you're trying to flash a bios from a card that uses Hynix then that's asking for trouble.

I would still be careful as there is more too it than differences in memory i do not think it would blow up the card straight away just cause a problem later on ....its more so to do with power delivery settings within the bios but i am no expert on this Laithan may be able to shed more light on this

WF3OC and G1 have an identical PCB, totally fine.. that's not really an "exception" when the PCBs are identical wink.gif. It's the same PCB DESIGN and MEMORY BRAND that should be paired together when looking for a matching BIOS.

When we have the ability to MOD the Pascal BIOS we can apply all the needed/requested tweaks you want using the original BIOS that came with the card.

Got tired of waiting for a BIOS modding tool and did the hard mod on xDevs. smile.gif Just soldered a small wire over resistors RS1, RS2, and RS3, did not add resistors to any capacitors, I just kept it easy.

Before (120% power limit, +170 core, +500 VRAM), Vcore bouncing between 0.981v and 1.031v with clock speed between 1965MHz and 2025MHz.



After (same OC settings as above), Vcore stable at 1.062v and clock speed stable at 2062MHz.

Where do we get BIOS for our cards if the manufacturer doesn't list them?
Is Techpowerup's database the best, despite missing quite a bit of stuff?

MSI removed the 1070 Gaming X BIOS from their site, but for some reason left the 1080 Gaming X BIOS.
They also haven't put anything up for 1070 or 1080 Gaming Z or Gaming non-X non-Z.

They just have an update tool, and as an owner of a 1070 Gaming 8G (non-Z or X) it will likely try to give me a BIOS for the card I obviously have, not allowing me access to X or Z BIOS's.
Currently I've flashed an X BIOS to my non-X 1070 and would like to get updates if they become available for it, or I may upgrade further to the Z BIOS if I can find it.

You can always dump a BIOS from your card. Either by software or soldering the chip to a reader.

The thing is, the 1070 is only missing a few components from a standard 1080 PCB. I would try and solder those to a 1070 with a 1080 BIOS.

They are the ones listed below. So if somebody has the original 1080 PCB I would need some values, The thing will differ from VRAM chips not being GDDRX. Worth a try.
