Hi All,
The the copy of the MSI Gaming X 1070 vBios version number 86.04.26.00.3E in the unverified section of the techpowerup DB was extracted from my card and submitted by me.
In all the online reviews I have seen, including the one on this site, all the review sample cards seem to have Samsung GDDR5 Ram installed and all seem to be running the 86.04.E1.XX.XX versions of vBios. That includes the reviewer sample OC bios and the customer bios version. I have just noticed that my card, purchased in Hong Kong, is running Micron memory.
I suspect that the 86.04.26.00.XX vbios versions are being used for the Micron versions of the cards. I have no idea if cross flashing the bios to Samsung memory will cause any issues or not. I have attached the GPU-z screenshot below. Don't worry about the PCI-E 2.0 reference, the card is currently installed in a Z68 motherboard with an overclocked i7-2600 (non K) CPU and the board does not have any PCI-E 3.0 lanes.
I would be interested to be able to compare notes on memory overclocking differences between the Samsung and Micron variants. So far, I have found on my card, that anything much more than about +400Mhz on the RAM slider in Afterburner will end up either giving me a 0x119 video scheduler BSOD, a DPC Watchdog BSOD , or the screen will break up into a white checkerboard pattern and either recover or crash and restart the PC. The DPC watchdog BSODs have stopped with the .95 Hotfix drivers but it just pushed the problem to the Vid Scheduler to crash.
I will concede though, that the BCLK overclock of 105.0 to 105.8 may be part of the limiting factor in the oc limits, I have observed the instability at high memory over clocks seems to be worse with DX12 than it is with DX11 - I can run higher overclocks in Fire Strike than I can in Time Spy for example. Possibly this will improve somewhat when I can put the card into a PCI-E 3.0 motherboard.
The other thing that I have noticed though is that on my 1070 at least, RAM overclocking up to the point where is goes unstable will give significant performance/framerate improvements. Looks to me that the switch from GDDR5X down to GDDR5 has created a bit of a memory bottleneck for the 1070. I have found that I get better results pushing memory forst and then catching up with core cloc speed/voltage adjustments.
The best 3dMark Fire Strike score with this rig I have managed so far is 14872 which was mixing it with some of lower tier machines with the same CPU and 1080, Titan X and 980TI cards.
