Just realized I put the wrong clock speed in my last post. I meant to leave the clock speed at 1080 and change the thread-concurrency to 10240. Regardless, it sounds like it's not working for you. I hope we can find a working solution for everyone.

Same issue here with 5x Sapphire on 041 bios. I can get it up to 730 if I can keep the temp under 65.
Would love to find the solution as the fans are at 100% and still can't prevent all the cards from throttling (usually GPU0 in a 4 card rig).

Also same problem starts to throttle when it gets hot.

Your GPU seems to be running at 99% so not really throttled. Try engine 1055 mem 1500 to see if you'll get better hash.
Can you post your VRM temp?

I just found this thread over on bitcointalk. They're describing the exact same issues spanning multiple OS's with the clock speed set at 1080.

Has anyone spoken with Sapphire about this issue yet?

I wrote to the Sapphire Support two days ago and sent them a 2 hour GPU-Z log. They replied me that these temperatures (VRM1: 110, VRM2: 80-90 degrees Celsius) are "normal". I responded immediately that is not "normal" the mentioned temperatures to be achieved by arrangement of 7 fans at 100% speed. If I remove the fans maybe my graphic card will be destroyed by the extreme heat:

Dear Sapphire Support,

I send you the 2 hours GPU-Z log with the following additional information:
- This graphic card is not the primary display adapter, i.e. my primary display adapter is the integrated AMD 6550D card in A8-3870K APU.
- The room temperature is 22 degrees Celsius.
- The PC case is opened and 7 fans (3x120mm Zalman ZM-F4 and 4x90mm Zalman ZM-F2 Plus) at 100% speed are arranged to increase income and outcome airflow.

----------------------------

Dear Sir:
According GPU-Z log file, the card temperature is normal.

----------------------------

Is it "normal" to use 7 additional fans to achieve this temperatures? Add this fact to the marketing description of the card.

What about VRM temperatures? I've noticed that at these temperatures the card performance is at least 25% lower than the previous batch with BIOS 015.039. This situation of unpredictable performance of Sapphire products is very disappointing for your clients.

Thanks for your feedback about your experience with Sapphire support KlimBo. Do you think it would be helpful to refer them to these forum threads? We need more people to report these issues or they will just continue to describe this as "normal operation".

In my opinion (as an employee in IT industry), definitely it is highly required more and more people to report these issues to Sapphire and their support to be referred to these forum threads. There are similar posts in different forums and blogs of people with the same problem.

For everyone else's reference, high VRM temps seem to be a normal thing for the Vapor-X models at least dating back to the 7950. The link below describes these issues in detail and steps through some modifications to help cool the VRM's, however, it requires some skill, parts, and patience. It does sound like they have added some changes to the newest bios version rather than fixing the physical heat dissipation problem that has existed for a while.

Makes sense from their standpoint. Why make assembly line modifications if they can change the software and achieve the same "affect"? They're sacrificing performance for us and they probably don't care as long as they don't get as many RMAs. It's a shame.

It also looks like rather than fix the Vapor-X model they released the Toxic series which adds heatsinks to the VRM's instead of the thermal pads.

Slap on some extra heat sinks, another fan, and OC it a little more. Ask for more $$.

I am totally speechless. I've paid more than 330 euros for a graphic card which has a similar performance (630 kH/s) to my Sapphire 7850 Dual-X OC for 150 euros (400 kH/s). Shame on you Sapphire.

I've just undervolted these Sapphire  (041 bios) to 1.094v using cryptobadger guide and they're now running stable at 730kh/s @65C with fan running 800-900RPM less than before (engine 1055 mem 1500).

Thanks for the feedback alphageek. When the temps exceed 65C does the card still throttle back? I'm curious to know how much power youo're saving with that configuration as well. I need to undervolt mine. :)

I don't see any throttling anymore so far (been running 30mins). 

GPU 0 Gigabyte OC Rev 2
GPU 1 Sapphire Vapor-X
GPU 2 Sapphire Vapor-X
Before, the throttling seems to varies as it related to VRM temp, not GPU temp (e.g. I have 1 card being throttled at 70 and another at 62).
Power saving is about 50W per card.

Thank you ... this helped me a little bit.
I have the same problems with these vapor-x cards (bios 041  :-\ ). I've been trying for days to get good results, but without success.
I've built a rig with 3 of them.

I use the following cgminer (3.7.2) settings:
-------------------------------------------------------------
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
DEL C:\Users\Mining\Desktop\cgminer-3.7.2-windows\*.bin
C:\Users\Mining\Desktop\cgminer-3.7.2-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 8192,8192,8192 --gpu-engine 1055,1055,1055 --gpu-memclock 1500,1500,1500 --temp-target 66,66,66 --auto-fan
--------------------------------------------------------------

And I undervolted my cards to 1.093V like you. I use the utility TRIXX under windows 7. The power saving is great. My system runs between 750 and 810W.
With --temp-target 66 I keep the temp at 63 - 65 degree.

But I can't get the cards to 700Kh/s or more .... My results varies between 630 and 670 Kh/s per card.

Where is my mistake? Or could you please post your complete settings?
