Massman Posted November 7, 2011 Author Posted November 7, 2011 NB does make a difference, but not 15FPS. Jumping from 2000NB to 2500NB gave me +~3FPS in GT4. Quote
Massman Posted November 7, 2011 Author Posted November 7, 2011 Running 3-way, GT1 goes down 10%. The decrease in GT4 is slightly larger, but that is what we expect from a more GPU-bound subtest. // edit: played with affinity. - C0 = 24.6 FPS - C1 = 24.7 FPS - C0+C1 = 42.01 FPS - C0+C2 = 51.14 FPS - C0+C1+C2 = 60 FPS - C0+C2+C4 = 67.39 FPS - C0+C1+C2+C3 = 71.2 FPS - C0+C2+C4+C6 = 75.21 FPS - C0+C1+C2+C3+C4+C5 = 80.44 FPS - C0+C1+C2+C3+C4+C5+C6+C7 = 82.81 FPS // edit2: Looking at this this score makes me even more confused [hwbot=2195471]submission[/hwbot] GT2, GT3, GT4 are on par with Bulldozer and Thuban. For some reason GT1 is the only subtest that is getting major performance hits. Also, GT1 isn't supposed to scale with frequency it seems. Stelaras has better GT1 with 1GHz less CPU power and 50MHz more GPU speed. [hwbot=2187323]submission[/hwbot] Quote
dinos22 Posted November 7, 2011 Posted November 7, 2011 in terms of score ratio comment you really need to be testing exactly the same settings to see if it is just the extra frequencies on various parameters that contributed to strangeness Quote
_mat_ Posted November 7, 2011 Posted November 7, 2011 Yea it wont go higher than 2.7-2.8 on air, i just saw a chart AMD made somewhere it said to expect 3-4ghz CPU NB clock under LN2, so i was wondering.Tried to get it up an friday and I'm stuck @ about 2.8. CPU was just at -20 °C, but it didn't show any scaling before so it was just for safety reasons. Quote

It's probably due to software and/or NB clocking. Quote
Massman Posted November 7, 2011 Author Posted November 7, 2011 Two new top scores for AMD platform, I think. 7G was rather unstable ... need to try again. Quote
Christian Ney Posted November 7, 2011 Posted November 7, 2011 Really nice testing you did. want to see 4k and 18k though Quote
TaPaKaH Posted November 7, 2011 Posted November 7, 2011 so at 10GHz, AMD might have a shot ... bring on the high leakage samples Quote
Hondacity Posted November 7, 2011 Posted November 7, 2011 I have a feeling somebody will try lapping these gigahurtz monsters lol Quote
Massman Posted November 9, 2011 Author Posted November 9, 2011 Boy oh boy, did I waste a lot of time with inefficient settings ... Fiddling in the BIOS gave me this: Quote
fuzz3l Posted November 9, 2011 Posted November 9, 2011 Nice PJ! What brings you the perf gain in Physiks (1400p or 14%) and Combined (600p or 8%)? Thats huge for just a BIOS option... _ Christian Quote
Massman Posted November 9, 2011 Author Posted November 9, 2011 4G NB also worked, but couldn't get the clocks up to 7G then. Quote

Thats huge for just a BIOS option... _ Christian I got the boost when I changed two things, but didn't have enough LN2 to check which of the two was causing the actual gain. I did: - run NB 1:1 with HT Link - lower memory multiplier from 1:4 to 3:10 I spoke about this gain with Macci and the best we could come up with is that choosing a lower memory multiplier is tightening up the memory in some way. This probably in combination with a highly overclocked CPU and NB. I didn't see this kind of bottleneck on air cooling. I think Leeghoofd is picking up the gear tomorrow evening and can't keep the cards for much longer anymore either, so further testing will be for another time, I think. Quote
just_nuke_em Posted November 10, 2011 Posted November 10, 2011 How many volts did you have on the cpu-nb if you don't mind saying? Quote
Massman Posted November 10, 2011 Author Posted November 10, 2011 FYI, this is the data I kept from air pretest runs. Quote
Hondacity Posted November 10, 2011 Posted November 10, 2011 linear scaling? show a graph please Quote
