.....anyway managed to source a cheap msi 980 4 g and i mean cheap ...been testing and i am able to get 1492 core and 8050 mem after that results diminish and this is with stock voltage with 65% ASIC not sure that means anything really ...
So my question is do you know of a thread re msi 980 4g good bios mod ect....
You are all too kind to me. My other virtual family
The ASIC %, well it is just a general reference
Unless.. (Click to show)
(EDIT: Unless you are EVGA, then it is a reason to price gouge!
but nothing definitive TBH. Some with low ASIC's can overclock pretty high.(sorry couldn't resist the edit)

The MUMOD settings will actually work with that MSI card also. You'd have to copy all the settings over to YOUR BIOS but those cards are also a custom PCB, have (2) 8-pin PCI-e and isn't voltage capped. Please report the results and PM me if you need any help

post DD versions of the betas now but for any "in between testing" I don't, only because I personally with DP and I'm usually making changes all the time and re-flashing.
You don't have to wait for me though, if you wanted to test it you can just grab the DD BIOS from the OP, compare the two side by side and make the changes manually.
This is looking very much like it will be the actual V4BETA

I was playing the mission Fresh meat, and as soon as I reached the place where the mission was set, my FPS dropped from 60+ to 10-20!! I nearly had a heart attack!!!!!
I immediately looked up at the OSD and it looked like the GPU utilization dropped near to zero!!!
The CPU was at full frequency and high load so I kind of exclude it. There's something wrong with the GPU!!!!
The're this area on the left of the graphs where GPU Load and Memory controller load dropped to 10% - 0% something like that.
Temps were normal, 60-65 degrees (air cooler, custom fan curve).
AB settings were 1524/8200 @ 1.187v!
I was testing for stability because +13 MHz on the core clock crashed afer 30 mins of gaming on GTA. And this happens! OMG I'm so scared now! Please, I don't want to have to RMA my card
I was thinking...could it have been the memory clock way too high? I wasn't getting any artifacts though...
Any help will be greatly appreciated. I'm kind of terriried now...
It's not a big deal. I suspect your low voltage test was insufficient voltage to maintain stability at that speed. That's lower than I've ever tested and I am not surprised at all that you are getting VREL perfcaps and odd results
I wouldn't go less than 1.2xx
v TBH but everything is worth a test so thanks for sharing the results.
This means for a 980Ti
we've seen (this is a limit through testing, more or less voltage IS possible):MINIMUM VOLTAGE = 1.200v/1.206v
(less appears to be insufficient voltage)MAXIMUM VOLTAGE = 1.231v/1.237v
(more introduces a major throttling bug that is hard to catch because it occurs in about 1/8th of a second, but drops clocks to ~700Mhz under load! Could be clock blocking)
One thing for sure is that we know GM200 cannot handle voltage like GM204 could
at least with what we know now anyway. GM200 shows that MORE VOLTAGE = LESS DIFFERENCE with regard to overclocking and higher performance and in most cases NO DIFFERENCE (apparently this does
change at 20C and colder
The good news is that despite the lack of voltage variance under max loads, it seems just about everyone's GPU overclocks the same regardless of the voltage. Meaning the overclocking headroom
doesn't appear to scale AT ALL when voltage is modified. This unfortunately means things are that much more "SILICON LOTTERY". This also could just be a result of the engineering changes...
In fact, the latest testing seems to indicate that longer term stability can be obtained with even LESS VOLTAGE
than what Gigabyte uses in it's STOCK BIOS
