Massman Posted November 3, 2011 Posted November 3, 2011 Getting ready, scores and more information is for the next coming days. SETUP: - 2x Bulldozer FX-8150 - GIGABYTE GA-990FXA-UD7 (F5 bios) - 4x MSI GTX 580 Lightning - 2x Dominator GTX2 - Silent Pro 1000W - AX1200 Big thanks goes out to the boys at Tones.BE as well as GIGABYTE HQ and of course the legendary Macci from AMD !

Massman Posted November 3, 2011 Author Posted November 3, 2011 I'm still installing ... nothing more I can do at the moment. Wait for the first 3DMark11 at stock speeds Quote
Massman Posted November 3, 2011 Author Posted November 3, 2011 +6.25% in CPU clock = +14.77% in Heaven DX11 Quote
Crew Leeghoofd Posted November 4, 2011 Crew Posted November 4, 2011 Good to see you have dual channel going now ... want to try some new rams ?? ps : don't kill the PSU Quote
Massman Posted November 4, 2011 Author Posted November 4, 2011 4250 MHz: +6.25% in CPU clock = +14.77% in Heaven DX11 4500 MHz: +12.5% in CPU clock = +23.79% in Heaven DX11 4750 MHz= +18.75% in CPU clock = +29.07% in Heaven DX11 Quote
Massman Posted November 4, 2011 Author Posted November 4, 2011 So far, though, I haven't found any clock wall ... Quote
Christian Ney Posted November 4, 2011 Posted November 4, 2011 So far, though, I haven't found any clock wall ... haha in da face Intel Quote
dinos22 Posted November 4, 2011 Posted November 4, 2011 LOL at the clock wall remark what about a performance wall Quote
Massman Posted November 4, 2011 Author Posted November 4, 2011 There's no wall. There's crazy scaling !! Quote
dinos22 Posted November 4, 2011 Posted November 4, 2011 just skip to 6Ghz and start testing "scaling" hehe Quote
Crew Leeghoofd Posted November 4, 2011 Crew Posted November 4, 2011 does he get another cpu if he kills it ? you know Massman when he's on a roll Quote
Massman Posted November 6, 2011 Author Posted November 6, 2011 Ran my first 3DMark11 with this setup and the score turned out better than anticipated. Maybe we had some performance issues at LITS2011 before ... Quote
Massman Posted November 6, 2011 Author Posted November 6, 2011 Before I go LN2 on the CPU, I need to return to the F5 bios to check some performance issues. I'm getting consistently 100p lower in Heaven DX11 on F6/G2 BIOS than I got with F5. I did reinstall the operating system (did that with F5 too), so maybe it's a software issue. Quote
Massman Posted November 6, 2011 Author Posted November 6, 2011 F5 BIOS is roughly 200p faster in 3DMark11. I gives a boost in the graphics score of the benchmark. Last score for today. System prepped for LN2 run tomorrow. 7G, here I coooooooome !! Quote
dinos22 Posted November 6, 2011 Posted November 6, 2011 the problem areas are still there the way it looks to me GT1 & PT/CT scores don't forget we didnt run NB higher than 2000 or so too and memory was left at auto Quote
dinos22 Posted November 6, 2011 Posted November 6, 2011 also 1100T or 1090T will beat BD scores imo http://hwbot.org/submission/2180076_dinos22_3dmark11___performance_4x_geforce_gtx_580_15233_marks look at this run with lower GPU speed and CPU frequency look at GT1 1090T eek Quote
Massman Posted November 6, 2011 Author Posted November 6, 2011 Nice catch, Dino! GT1 seems to be the most problematic game test for Bulldozer. The three others are roughly on par with Thuban. Given the Bulldozer architecture, I'd say the PT score is fine too for a 4 module chip. Combined isn't too big of an issue. // Edit: If GT1 would be so low due to the it's CPU-intensive nature, increasing the clock frequency of the CPU should yield in great scaling of GT1. Or at least greater scaling than the three other game tests. GT1 4500 MHz = 86.28 FPS GT1 4625 MHz = 87.74 FPS GT1 4750 MHz = 87.85 FPS (on F5 bios, 4750 = 89.61 FPS) I don't understand why GT2 is getting worse when increasing the CPU frequency, though ... // edit2: Also, GT1/GT3 ratio of my scores compared to Dino's is very strange: vs Quote
matose Posted November 6, 2011 Posted November 6, 2011 I still don't understand why you are playing 4xSLI with Bulldozer. Are you a masochist or something? SB-E at 5GHz will score way better that FX-8150 at over 7GHz. With 4xSLI you need a lot of CPU power for the VGAs to scale which you could not get with Bulldozer... Quote
Massman Posted November 6, 2011 Author Posted November 6, 2011 Lol! I test Bulldozer for the same reason I play with IGP or like to play with the Athlon XP once in a while. I'm not interested in breaking world records or getting top scores, I'm just interested in seeing how the platform behaves and how you can maximize the results. It doesn't make sense that GT1 slacking 15-20FPS is only due to a lack of CPU power. For one, all three other GTs are perfectly on par with Thuban. For two, increasing the clock frequency of the CPU doesn't really make GT1 scale; the scaling is identical to the other tests. Quote
matose Posted November 6, 2011 Posted November 6, 2011 Try 2 things: 1) Deactivate 1 core per module and test again to see if it's an arhitecture problem 2) remove 1 VGA card to see if the CPU is underpowered Quote
sin0822 Posted November 7, 2011 Posted November 7, 2011 Did you try adjusting the CPU NB to better relate to your clocks? Under LN2 supposedly you can really turn up CPU NB for a lot better performance, though i didn't try. Odd issue. Quote
dinos22 Posted November 7, 2011 Posted November 7, 2011 NB doesnt clock well on BD compared to older CPUs with a little messing around i did in london Quote
sin0822 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. But i know for high GHZ you keep it low, but i guess if you were aiming for performance you might wanna raise it, no? I guess this is the only time anyone goes for BD performance. Quote
