Hey guys, just got my sig rig up and running and I noticed that i'm not getting quite as much performance as I expected out of my setup.
IE in WoW full fully maxed settings, vsync off, triple buffering off, refresh rate set to 120hz in nvidia control panel and in game i'm only at 45-50fps in org (of course area 52 is a mega populated horde dominant server so I don't expect to be rocking 120fps there at peak times) and outside of org im averaging maybe 74-90 fps. I know there were quite a few vast improvements made to the graphics engine since patch 5.0 but jeez upon 4.0 release my 955be @ 4ghz and 6850 crossfire was giving me similar fps (albeit on a lower population server) but crazy cpu load aside, when i'm alone in a area im getting roughly the same fps showing as my old setup although it feels MUCH smoother and more responsive than previous setups at the same reported fps values.
CPU load is at 25% at peak time in org and it's properly boosting to 4.6ghz upon wow launch.
Afterburner is showing both cards receiving load and SLI IS being recognized by WoW and utilized. Load fluctuates per card between 25 and 60% (it juggles the load between the cards, it'll jump from 25/60 to like 50/30 etc) i'm not sure if that's an indication of throttling or what for the lightnings.
Also, when streaming in org im stuck at around 20-34 fps (50%cpu load) which is just crazy for this setup no matter what settings I try with xsplit and around 54-100 else where in very low pop zones.
Could it be that wow just isn't stressing the cards much or the system and it's throttling back?
Please let me know what you think.
Is that Heaven run with the cards at stock? Forgot what I run stock or overclocked, been a while since I've run Heaven. Someone else might be able to jump in and let you know if that score is average. But for WoW...how's your internet connection? Never was a Warcraft fan so I'm not sure if there's a single-player mode, but if you have a game like BF3 for instance, try single and multiplayer mode in that and look at the usage difference. I get ~70% max usage on each card in SLI during a multiplayer match, but in singleplayer they're at 99% the entire time. With no CPU cores maxing out during either, I can only conclude it's something to do with playing over the network that is causing the lower usage.
Try a single-player game and see if you get full SLI usage.

If you run afterburner 2.2.3 and the ln2 bios, yes
some have oc'd to 1400+hz core and 7300+hz mem
...the odds of getting one of those cards now is significantly lower than when we all got them on release day and got 1340mhz before we even had voltage control. Many now will only hit low 1300's, like my latest. Obviously golden ones are still out there, but I think the binning process has lowered the bar since the cards started coming at 1111mhz like my latest one, instead of the 1202mhz on the unlocked LN2 BIOS back before this latest fiasco with Nvidia.
Bottom line is this is still the best card on the market- the ONLY one that doesn't throttle at 70C, the ONLY one that allows for 100% fan speed, one of the few you can crank the voltage up to ANYTHING you want, and arguably the best cooler on the market as well. So, still a great buy, don't get me wrong, but I think the days of every few buyers getting a 1400mhz card on the stock +93mv are over.
I read an AMD-related thread the other day and was amazed. They were all temperature-limited at only ~1200mhz and ~1.1v. Even 7970 Lightning's have trouble getting much higher than 1300mhz. It's pretty amazing how cool these chips run. I remember doing Heaven runs at over 1350/7000 with ~1.3v and only hitting low 60C's.Edited by dph314 - 9/23/12 at 1:35pm
