(This data is from the techpowerup database of BIOS: )Ĭlearly there have been many releases of BIOS made available since September's 84.04.1F - revision 84.04.28 in early October, 84.04.2F in late October, and finally 84.04.31 on the 19th of November: this is the revision that nvidia is referring to in their post about the resolution to the displayport problems. Second, let's look at the BIOS release history of a vendor with a more active policy of BIOS releases - MSI in this case: The nvidia post that advertises the newly available BIOS was in November 2014, but the ASUS BIOS was compiled much earlier than that, in September 2014. I will present two pieces of evidence that the currently shipping ASUS BIOS version is older than the version specified by nvidia.įirst of all, the date. in this thread ) as to whether this BIOS is actually newer than the one specified in the nvidia thread (84.04.31.00.00) - the fact that the version number includes hexidecimal digits is perhaps part of the problem, maybe along with the fact that 1F in hex happens to be the same value as 31 in decimal.

Running the ASUS gpu tweak software informs me that I have the latest BIOS for my card, which is: Not to belabor the point: this is *really* inconvenient. the ring light turns off), I can expect that when I bring the system out of sleep that the monitor will be indicating "no signal" and no amount of power cycling of the monitor, unplugging/replugging of the displayport cable, etc. If my system goes to sleep for long enough for the SWIFT to enter its sleep state (i.e.

The problem occurs for me even with the latest driver or that specific hotfix driver, and the other suggested PCIe setting related hacks are not effective or applicable (I have a somewhat older motherboard, an ASUS P6T). In my case, I have an ASUS STRIX 970 connected to an ASUS ROG SWIFT - so displayport is the only possible option for me. The suggestion is that the driver *may* fix the problem alone, and if it does not that the new BIOS will be required.
The thread on the nvidia forums describing the issue is here - this link goes directly to the nvidia response, which indicates a two part solution to the problem: a new driver (344.80) and a new reference BIOS (84.04.31.00.00). Different driver revisions appear to express the problem differently, and more recent releases solve the problem entirely for some people - but not all.

There seems to be a lot of misunderstanding surrounding the updated reference Maxwell BIOS - there are several threads inquiring on this topic but many of them are confused as to what the necessity of the BIOS update or whether it applies to the ASUS cards at all.īackground: many Maxwell cards have had significant issues with output on the displayport connector, exhibiting a black screen in various situations: on initial boot, after restoring from sleep, etc.
