I've just noticed an additional problem with my Sapphire 280-X Vapor-X  >:( If CGMiner 3.7.2 is started with --auto-fan or Sapphire Trixx is used to control card's fan the speed jumps to 100% for 2-3 seconds and drops to 0% for 5-6 seconds and this behavior repeats constantly.

With the version 3.7.2 i had problems too. It runs very unstable.
I have tried a few other versions today. CGMiner 3.5.1 seems to be the best choice for me.

Now it runs stable between 670 and 680Kh/s per card with the following settings:
-------------------------------------------------------
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
DEL C:\Users\Mining\Desktop\cgminer-3.5.1-windows\*.bin
C:\Users\Mining\Desktop\cgminer-3.5.1-windows\cgminer.exe --scrypt -o stratum+tcp://XXXXX:3333 -u XXXX.XXXX -p XXXX -I 13,13,13 -g 2 -w 256 --lookup-gap 2 --thread-concurrency 8193,8193,8193 --gpu-engine 1055,1055,1055 --gpu-powertune -20,-20,-20 --gpu-memclock 1500,1500,1500 --temp-target 66,66,66 --auto-fan
-------------------------------------------------------
And  undervolting to 1.093V.

I hope I will find a way to improve the settings to get 720 - 730KH/s or so ...

I'm very interested what settings alphageek has made.
Or have someone else a solution/idea for the problem? .... let me know  ;)

It's very frustrating. In my gaming-pc i have a gigabyte r9 280x rev. 2.0 ... There I get 725 Kh/s with very simple settings and without overclocking, undervolting, ...

Software used is: VBE7 BIOS Editor, atiflash and bootable usb memorystick (atiwinflash locks up when flashing, luckily no bricking).
Downloaded sapphires' r9 290 bios release, ran the hp util and copied atiflash and the bioses to the usb memory stick.
Bios obtained from Techpowerup's vga bios collection.

I've kept to the 15.039 version bios for dualx, vaporx and toxic edition.
Results:

Dead outputs on all bioses (earlier sapphire bioses, msi bios, sapphire 7970 bios). I thought I fixed it and got working outputs with the MSI bios but I realised later I was just running off onboard! Doh.

The card does get detected in windows though and mines if using the msi bios and onboard as primary.

Otherwise only the original (backup) bios  flashes and results in no dead outputs. Some good news, using the orignal backup bios, vbe7 works. So at least with a bios editor I can affect the default clocks and volts.

Think I'm getting a bottleneck as well as I'm using a 280x & 7950 on the same motherboard, tho the 280x is just a 7900 series card all but in name more or less. If I remove the 7950 I canget 700kh/sec with the 280x (but then I get better temps of course and lack of possible bottleneck...).

Anyway looking at the bios thru vbe and techpowerup, even tho mem is autodetect I notice my vram is a different brand than what most bios have. Maybe that can explain the disabling of outputs? Or is it the lack of uefi bios? The card should just work in legacy mode? As well the original bios modified by VBE7 works and it disables uefi.

I notice on my card it has mem "Elpida Edw2032BBBG" and the vga bios available seem to have "Hynix H5GQ2H24AFR" listed. It shouldn't matter what brand as it meets a spec, so I guess I grasping at straws :).

Once last try I'm going to try the 290 bios sapphire released and then modify the clocks in vbe, all the dualx bioses (lists my brand at least and one of them contains uefi).

Results:
1st bios works - made sure to be plugged into its outputs and set as primary this time :). Looks like it either matters that UEFI is present in the rom file and or Elpida is specifically stated that its supported in the rom file. So yeah dualx with uefi present and my memory brand supported in the rom file works and is 15.039. So I finally find a BIOS that works but mining crashes the driver, guess I have to find a good voltage.

OK think I answered my question, after editing the 1st bios that uefi present in the image and then disabled by vbe7 it still works.  AS its powertune settings were different than the original bios, I just copied the values from the original bios into the modified bios. Hmm adjusting the power adjusts the tdp :-/. Cgminer still crashing. Hmm think its to do with the voltages being locked (?) in the dualx bios, played with same of the vddc and tdp settings and still crashing. I notice when setting the clock with trixx or msi ab it doesn't change from 1v, whereas if using the original back it changes. Thus no doubt why cgminer crashing the display as not enough volts are going to the card. At least the original backup still works.

Also i think I know why people get no posting - I think its due to the bios you are flashing with is for Hynix vram vs Elpida (your gpu most likely uses Elpida vram). I'm lead to believe this as the only bios image to work to date lists Elpida as supported. All the other bioses that don't display video only support Hynix.

Is someone able to post up a link to a downloadable bios image that is for v15.039 and your vram is Elpida. You can find out by opening your bios file in VBE7. Memory Types should listed Elpida EDW2032BBBG - if it lists Hynix only don't bother (can list both tho but Elpida has to be present). Thanks.

CGminer still crashes, so I think I'll have to go back to the original bios for now until I find a bios that works for both display and mining. At least i know now to target my memory type as far as bios images are concerned.

Results so far...

tldr version for bios image v15.039 or earlier:
ATI bios - no display
HIS bios - no display
Gigabyte bios - flakey the display works sometimes, so i'd pass on it.
MISO bios - no display
Sapphire bios - no display
XFX bios - all versions with display and no cgminer crash.

XFX bioses are good, esp the one that sets the clocks to 1080 but you might want to drop the volts. v15.039 & v15.040 I'm going to go back to v15.039 to be safe since its a known good bios version.
As much as I find a good bios I think I'm being capped by my  config of 280x + 7950 as they seem to copy each others hash somewhat and I'm not using crossfire.


I'd be interested to know if the XFX bioses that match your vram fix the throttling issue.

Are you saying that the XFX works on these cards?

I'm royally pissed with Sapphire for this stunt they pulled. I have a 39 card and tested it for a month before deciding to build a rig with 3!!! more of these cards. Took me days of debugging and guess work, switching and buying new risers, before I found this thread (which I'm glad I did)

I've flashed legacy uefi roms of my 39 and nothing works. Unfortunately I think the 39 are meant for Hynix so I guess there is none with Elpida config. Right now I've flashed my cards with vddc of 1.093, set it to 65 target temp and getting around 680 hashes.

I've ordered some huge industrial heat sink over the web and will try stick to the back plate and see if it improves the temp and performance.

I don't have permission to edit the https://litecoin.info/Mining_hardware_comparison If someone does, please kindly update this to the page for the benefit of people like me getting fooked by sapphire.

My settings are
--gpu-engine 1055 --gpu-vddc 1.094 --gpu-memclock 1500 --temp-target 66 --temp-overheat 70 -I 13 -g 2 --worksize 256 --shaders 2048


the GPU2 is a 39 bios and the rest are 41

Some additional info that I managed to dig out from the net
http://www.overclock.net/t/1394623/belials-comprehensive-guide-to-7950s
seems like we are screwed with the Elpida rams

I'm very tempted to mod the board right now either modding the heatsink like the link wobbzz posted http://www.techpowerup.com/forums/threads/how-to-curb-excessive-vrm-temps-under-full-gpu-load-on-sapphire-vapor-x-7950s.186666/ or look for a waterblock that covers the vram (which I don't think exist until I talk to the local liquid cooling expert).

Or just let it burn out in 1 year running max fan and replace them since cooling them with blocks will cost a bomb and I'm losing about 10% of the hash rate

hello dear friends,
i have the same problem with you guys, the 015.041 bios of sapphire r9 280x vapor-x
anyway, i made a deep search for a week and i now i get 720 kh/s without undervolting or changing bios, take a try of this script:
--lookup-gap 2 --thread-concurrency 8193 -g 2 -I 13 -w 256 --auto-fan --gpu-fan 30-85 --temp-cutoff 90 --temp-overheat 85 --temp-target 70 --gpu-memclock 1500 --gpu-engine 1052 --gpu-powertune -20

i found some other good performing scripts too, maybe they work better than me for you:
--thread-concurrency 11200 -g 2 -w 256 --gpu-engine 1032 --gpu-memclock 1500 --gpu-fan 65 -I 13 --gpu-powertune -20 (requires vddc 1093)

-g 2 -w 256 -I 13 --lookup-gap 2 --thread-concurrency 8192 --gpu-engine 1020 --gpu-memclock 1500 --gpu-powertune -20

-g 2 -w 256 -I 13 --lookup-gap 2 --thread-concurrency 8192 --gpu-engine 1020 --gpu-memclock 1500

--thread-concurrency 11200 -g 2 -I 13 -w 256 --auto-fan --gpu-fan 40-65 --temp-overheat 85 --temp-target 71 --gpu-memclock 1500 --gpu-engine 1080 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale

c ya ;)

Yes xfx bios works. I have Elpida.. sucks to hear about Elpida maybe being the culprit... I think I'm still stuck with the issue as I can't get 700 khsec again (sold off the 7950 so only a single gpu setp atm).

Unfortunately in all the testing I've overwritten both bioses to xfx. Can someone with Elpida vram or this issue (at the very least) link to a copy of their bios image? I've emailed Sapphire for a copy but someone here maybe quicker.

Thanks

Thanks, can you post the uefi rom just in case I need to rma the card? I've created a support ticket and told Sapphire about this forum thread..

Hopefully they have a fixed bios or can send me some vbios to try (I've asked for 015.041.x, 015.040.x, 015.039.x).

I also said its disappointing they won't acknowledge and fix the problem, heh.

XFX Works as far as booting and displaying but  doesn't get the 700 khsec.

Using the legacy rom I get 710khsec~. Temp is at 73C for GPU.

OMG it works! i'm getting 710-720Kh/s. THANK YOU SO MUCH apulunas
I just tested undervolting (1.093) and normal volting and found no difference. except my fan runs at 2600rpm vs 3500rpm
I'm suspecting the --auto-gpu is messing it up as that was one of the key difference from my script

SO i'm going to leave it like this for a while until my industrial heat sink comes.

Pengo, I'll send you the EFI later as I'm running extremely late for my engagement. Cheers (i'm running legacy undervolted right now)

I'm getting 650/sec on a hot day now that cgminer has been running for awhile, i'm using:

--scrypt --thread-concurrency 8193 -g 2 -I 13 -w 256 --auto-fan --gpu-fan 40-65 --temp-overheat 85 --temp-target 71 --gpu-memclock 1500 --gpu-engine 1020 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale --gpu-vddc 1.093

Using some other settings vrm temps are 109/90 woah!

Using the following:

--scrypt --thread-concurrency 8193 -g 2 -I 13 -w 256 --auto-fan --gpu-fan 40-65 --temp-overheat 85 --temp-target 71 --gpu-memclock 1500 --gpu-engine 1032 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale --gpu-powertune 10

Results in a hash rate of 700kH/sec~ after 5mins, with vrms at 100C, 89C & gpu at 72c. Since cgminer is not setting the vddc I've used Trixx to set vddc to 1.088.

Sapphire support has replied to my ticket but state they can't connect to the thread. Either way I've asked for an earlier bios or the latest, so I can at least re-flash and the card will be stock standard.

Hey guys, I have also been in touch with Sapphire Support trying to figure out a solution.

In the meantime, I've created an Online Petition to try and get this into the attention of Sapphire (Althon Micro Inc) http://goo.gl/F6kSWj (Google Form).

If you have a spare moment, please show support the Online Petition by giving your name (initials/first name).

I'd like to post this up as a separate post if the moderators allow for it.

Cheers

PS. Sapphire Support did tell me to go ahead with flashing the bios :)

signed the petiton, I'm asking sapphire support for the latest bios or an earlier one than 15.041, tho they haven't given me one yet.

Have you told sapphire support the vrms run really hot? Ambient temp here is quite hot coz I live in a hot climate. I'm running with the side of the case off, otherwise if I run with the side on temps get to high. I've told sapphire I live in a hot climate as well. Furthermore I've told them I'm not the only one and through testing it has been found an earlier bios such as 15.039 works, though I seem to be ok with the legacy 15.041 bios. It could be just the uefi bios. I've also told them due to running Elpida vram and not hynix none of the techpowerup bioses work.

Looking forward to testing the uefi bios once it becomes available and hopefully sapphire support comes through for us.
