The stilt bios looks solid, but the first thing I notice that idle temperature is 7 degrees higher on both core and VRM while the gaming temperature is about 15-20
8-10 degrees higher on the VRM and 8 degrees higher on the core, which is very surprising.
I also did some comparison benchmarks:
Score 1: PT1T bios at 1150/1500 - 13 735 Graphics score
Score 2: Stilt bios at 1150/1375 - 13 841 Graphics score
Score 3: 390x bios at 1100/1500 - 13 950 Graphics score
Score 4: 390x bios at 1150/1600 - 14 655 Graphics score
Seems like Stilt's bios has an edge over the unoptimised 290x bios but 390x seems to perform a bit better. Is this only due to memory controller and timings changes?The first thing I will do is mod the Gigabyte 290x bios with my settings and test to see if the temperatures are similar.
Then I would try to play with the timings on Stilt's bios but from what I've seen about memory timing mods I think I may be over my head on this. Would be nice to get 14k Graphics for daily use though.
But my card barely gets firstname.lastname@example.org, and I wouldn't go past that for daily use, so it seems that the extra performance can only come from the memory.
Edit 1: It seems that the Higher VRM temperatures are due to me changing the rpm of the fan that's cooling them. Now that I changed it back I only get 85 degrees in load, instead of 95. It's still higher than 75 which is what I was getting with the 390x bios but it is pretty much expected.
Seeing that I could get the memory up to 1600Mhz using the 390x bios, could it be that hard to get tighter timings working at 1500Mhz?
So I applied Stilt's memory timings to all the memory straps.
@1.300v is stable. Even 1550 doesn't artifact on desktop but it does artifact in Firestrike.1150
/1375 @1.350v is stable.
1150/1500 @1.350v artifacts ocasionally in firestrike.
1150/1500 @1.368v artifacts ocasionally in firestrike. I read in Stilt's thread that this is the limit set in the rom.
1150/1500 @1.368v 1.039VDDCI artifacts ocasionally in firestrike.
Tried a bunch of combinations, the highest stable combination of both core and memory I got is:
Is there a reason why core and ram are stable at 1150/1500 but not both at once?Edited by madalin3 - 7/9/16 at 5:44pm
