fleisch Posted May 30, 2008 Share Posted May 30, 2008 Hi everybody. Once again i need some help... My System: Asus P5W dh deluxe, CPU: e6400@2.77 ghz, geforce 8800gt. Install: Kalyway 10.5.1 -> Kalyway 10.5.2 upgrade -> netkas method upgrade to 10.5.3 gfx-efi method (netkas) for graphics. ALCinject for sound. Now i saw some xbench results of ohter people using the 8800gt and they seem to have much better results in the quartz graphics tests here are my results: Results 194.81 System Info Xbench Version 1.3 System Version 10.5.3 (9D34) Physical RAM 2048 MB Model Mac Pro Drive Type SAMSUNG SP2504C CPU Test 174.09 GCD Loop 326.81 17.23 Mops/sec Floating Point Basic 157.66 3.75 Gflop/sec vecLib FFT 127.87 4.22 Gflop/sec Floating Point Library 173.80 30.26 Mops/sec Thread Test 207.76 Computation 195.89 3.97 Mops/sec, 4 threads Lock Contention 221.16 9.51 Mlocks/sec, 4 threads Memory Test 161.04 System 231.68 Allocate 283.23 1.04 Malloc/sec Fill 204.95 9965.15 MB/sec Copy 220.32 4550.63 MB/sec Stream 123.41 Copy 117.52 2427.39 MB/sec Scale 118.54 2448.92 MB/sec Add 129.10 2750.21 MB/sec Triad 129.50 2770.23 MB/sec Quartz Graphics Test 189.11 Line 209.62 13.96 Klines/sec [50% alpha] Rectangle 176.58 52.72 Krects/sec [50% alpha] Circle 268.52 21.89 Kcircles/sec [50% alpha] Bezier 94.53 2.38 Kbeziers/sec [50% alpha] Text 586.92 36.71 Kchars/sec OpenGL Graphics Test 174.59 Spinning Squares 174.59 221.48 frames/sec User Interface Test 331.45 Elements 331.45 1.52 Krefresh/sec Any help/ideas/suggestions are more than welcome!! thx! cheers fleisch Link to comment https://www.insanelymac.com/forum/topic/107737-why-do-my-xbench-results-suck-so-badly/ Share on other sites More sharing options...
knewsom Posted May 30, 2008 Share Posted May 30, 2008 hmm. Have you tried removing the EFI strings and used NVInject instead? My Quartz graphics test was at 305.60, and my UI was 554.42. Are you sure you have the card installed in a 16x PCIe slot? Is it a 512 card or a 256?

laatmaarzien Posted May 30, 2008 Share Posted May 30, 2008 Excuses for my ignorance, but does the NVInject method give any performance boost over the GFX-EFI method?

knewsom Posted May 30, 2008 Share Posted May 30, 2008 in theory, it shouldn't. I was just wondering if the OP had noticed a difference between the two. Trying to narrow down the problem.

fleisch Posted May 30, 2008 Author Share Posted May 30, 2008 Hey knewsom! thx for the reply.... ja i'm pretty sure that the slot is 16xpci...it works fine in xp, too. and it's got 512mb of ram... I don't know where the bottleneck in my setup might be... nvinject doesn't make any difference at all... btw... what install method did you use? thx fleisch Link to comment https://www.insanelymac.com/forum/topic/107737-why-do-my-xbench-results-suck-so-badly/#findComment-764702 Share on other sites More sharing options...
00diabolic Posted May 30, 2008 Share Posted May 30, 2008 Could be front side bus. OSX does not always read front side bus correctly. Like mine is read as 179mhz when its supposed to be 200 X 4 = 800mhz instead i get 716mhz. So I have to use a flag to correct it at boot. See my kernel flags list for details on FSB flags (under hacked kernel flags): http://forum.insanelymac.com/index.php?showtopic=99891 Leave a comment on that thread if you have success with one of those flags.

knewsom Posted May 30, 2008 Share Posted May 30, 2008 the FSB scenario sounds plausable, you should certainly look into that. Mine recognizes just fine though, 1.77 ghz. My install was Leo4Allv3, NVInject for video. I've been considering going with EFI GFX strings and ditching NVInject to speed up boot times and remove any superfluous extensions, but it's already very fast and rock solid stable, I'll give it a go when I have time, but for now, it's a great install, and my main computer.

fleisch Posted May 31, 2008 Author Share Posted May 31, 2008 hm...no the fsb is read correctly @ 1,38 ghz. any other ideas? will try to mess around with the bios settings a little bit...maybe that'll change anything? i don't know Link to comment https://www.insanelymac.com/forum/topic/107737-why-do-my-xbench-results-suck-so-badly/#findComment-765182 Share on other sites More sharing options...
knewsom Posted May 31, 2008 Share Posted May 31, 2008 hmm... weird stuff man. Are you running a vanilla kernel or a hacked one? If it's a hacked one, you'll need to boot with the 64 bit flag in order to not run in legacy (32 bit) mode. That could explain it, I guess.

fleisch Posted May 31, 2008 Author Share Posted May 31, 2008 no i'm running vanilla. I tried a bunch of stuff: bios update, different settings...still the same...and that with a pretty decent 8800gt I also ran 3dmark06 in windows to check if the hardware is ok...i got about 10500 marks... about as much as i would expect. so there doesn't seem to be a problem with the hardware right? any more ideas? thx for the help so far! cheers fleisch Link to comment https://www.insanelymac.com/forum/topic/107737-why-do-my-xbench-results-suck-so-badly/#findComment-765310 Share on other sites More sharing options...
ToGaR Posted June 17, 2008 Share Posted June 17, 2008 Let me know if you haven't solved this yet and I'll try to help you. I have the same card and my score are significantly higher than what you're showing.
