680MX Benchmarks please

Yeah Lubbo does not read the temps correctly, i just set the min and max to around 2200rpm, overclock using MSI Afterburner, then keep an eye on the temps while im gaming using the built in OSD that MSI Afterburner has. GPU never goes above 80c like this.

Yeah that's why I'm doing. Hopefully Lubbo releases an update for the iMac so it's a bit more... automated.

Lubbo fan control

Click to expand...

I downloaded it, and when I started it the fan started taking off, probably because of the default setting at 6000. I was trying to undo the effects of Lubbo completely, but just closing the program doesn't work and it doesn't have an uninstall feature and google didn't bring up any results.

Do you by any chance know how to get ride off it?

Update: Figured it out, looks like resetting SMC by powering down and disconnecting from power for 15 seconds solved it.

Yeah you have to power off the machine completely, even resetting it will keep then fans going.
 
I dunno about Win7 yet as I haven't bothered installing it, but WoW in OS X really isn't bad. Minus Shadows (never used them, mostly due to computer wanting to blow up) and Sunshaft disabled, this thing was rocking 70-90fps everywhere on mostly Ultra, High settings. (Far distance lowered to High). Did a couple quick dungeons and never saw any issues. Amazing how different things are when your computer doesn't act like it'll blow up at any moment. :eek:
 
To update on the buzzing issue from the 680MX under extreme load (Far Cry 3, Devil May Cry, Hitman: Absolution etc), I picked up a Kill-A-Watt device, which measures the power consumption from the iMac under load. I wondered if the issue was actually the graphics card, or just a general high-load issue due to the GPU+CPU load.

Turns out while playing Far Cry 3 essentially maxed out at 1920x1080, with the screen turned on to max brightness, the i7 iMac is pulling 235 watts or thereabouts. The buzzing is noticeable. When I turn the LCD brightness down to the lowest level, the system is pulling only 180 watts. The buzzing noise does NOT change at all. I can therefore deduce the issue is not related to the power supply, but is localized to the Geforce card, and is simply a GPU-load-based noise.

Anyone else want to chime in on this? I understand to some people the buzzing might not be very noticeable, and as I mentioned - in a lot of games that aren't so GPU intensive the issue isn't there at all. But if you play some graphically-heavy games like Far Cry 3, it really is something I personally notice, even above the fans. I do understand that some of you might not hear it, though...

Just wish I knew if I was just being sensitive or if it's something truly faulty. The iMac has no stability issues or anything like that... *sigh*
 
Any tried to check how many watt's the iMac uses when it is in full use?

Edit: OMG! Sorry WilliamG, I didn't saw your message. :p
225 Watts is a really nice number, my desktop uses over 500 watts excluded the monitor and audio. :)

Wow, the 200/300 overclock of 680MX works well! It certainly makes a difference playing Crysis: Warhead and Crysis 2 staying at 30fps or higher with vsync on. However, with Crysis 2 the CPU temp goes higher than other game I've tried. Maybe it's because dx11 supports hyperthreading. The graphics are just amazing though, it's the first dx11 game I've played, and being able to play in native resolution with all settings at max (except for post processing) is pretty nice. :D However, fanspeed must be 2350rpm at least to avoid the CPU temp going into the mid 80s. Yikes...
The 200/300 overclocking only adds a few extra celsius degrees, but the CPU and GPU are already pretty hot...

Could any of you guys try out the octane renderer?
http://render.otoy.com/
It uses the GPU to render instead of the CPU.
NVidia gives a good CUDA computational score for the 680MX but I'm wondering how it'll perform in real life.

I got 7126 in 3DMark 11http://www.3dmark.com/3dm11/5698873 with a GTX675MX card?? Is it worth the upgrade if the 2nd to high end imac can be "tweaked" to out perform the GTX680MX?

Ehrm, I get P8291 with my 680MX overclocked at 200/300 - with only minimal temperature increase I might add. I could easily go even higher if I turned up the iMac fan to max, but I'd rather avoid that...

Having said that, I really annoys me that Nvidia can't be bothered to put out a proper driver for the 680MX, as we are forced to use the 680M driver. I wonder how much performance we're missing out on? Looking at the card specs and comparing with proper GTX680 scores, the 680MX should have performed a bit faster than it actually does IMO.

Use MSI Afterburner. Also activate the On Screen Display (OSD) with (fps counter and) temperature monitoring. This way you can keep an eye on the GPU temperature. HWiNFO64 (for 64bit Windows) is also great for monitoring all temperatures (including CPU cores), fan speeds etc..

i overlocked to with 200/300 and using the automatic fan control of the imac. in far cry 3 i get gpu max 88 and cpu max 89 with fan speed max 2650 rpm. should i worry?
 
I spoke too soon, fan speed at 2350rpm, and GPU reaches 78-79C and CPU up to 85C. Guess I better crank up the fan speed to max... Yeah, good question.. Is it ok to run the iMacs CPU and GPU at temperatures of around 75-85C for several hours at a time? The Ivy Bridge is well known to run very hot, but these are high temperatures. I'm gonna try and play Crysis 2 again without overclocking for a couple of hours just to compare temperatures. Even without overclocking the iMac gets pretty hot while gaming...
 
but the imac itself don't get hot. i think this are only the core temperature of the gpu and cpu. and i think it's ok.

in gta iv the cpu gets 104. i think if the imac got to hot it will shut down so nothing gets damaged.
 
If you're getting 90+ celsius, I think you'd better back off the overclocking. Tolerances will vary with these 680MX cards, some units will fare better with overclocking than others. If I were you, try to go down to 100/200 overclock instead. Again, waiting for other "experts" to chime in on the temperature issue. :) Conventional wisdom tells me too high temperatures are no good if you want the hardware to have a decent lifespan. Have you checked the hard drive temperatures? I've read hard drives should be not become hotter than 60c.

Use HDiNFO64 to check all the tempeatures of your iMac. Hopefully someone else with more knowledge of temperature tolarances in modern hardware can give more information about this issue...

Have you checked the hard drive temperatures? Hard drives should be not become hotter than 60c. The CPU starts to throttle at 105c. 104c is HIGH! :eek:

i'm already using hdinfo64.

yes 104 is very high. but it hits only in gta iv. is a real cpu killer!

if you have it please run far cry 3 overlcoked and check your temperatures, beacuse far cry 3 is a real gpu killer! oc i get 88 and normal it's 85. so its only 3 more.

and i think the temperatures are ok. and if it to high the imac shuts down before some component get damaged.
i hope so :)#

ssd is 40 under load. in desktop 34.

Well, I took it to the Apple Store and Apple heard the issue and replaced the iMac. Just posting that here if anyone else has the 680MX and a really noticeable buzzing sound under GPU load. Replacement iMac (so far) does not have any buzzing to note under GPU load.

Good call. That buzzing could be a sign of bad hardware that would eventually fail at some point. Never heard any buzzing from my iMac..

So you have the 768gb SSD option? Congrats. :D Me too, I would imagine having a regular HD or Fusion drive would create additional heat. HDs are also more vulnerable to heat than most other computer components. Sorry, don't have Far Cry 3. But I'm playing through Crysis 2 with dx11 and high res textures... I'm loving this game! :D

I'm not sure there was anything "wrong" with the GPU. I just found it to be an objectionable amount of coil whine. At least one other user in this thread has experienced it, and it will depend to some degree on your tolerance. That the Apple genius could hear it in the busy Apple Store should be a testament to just how loud the buzzing was from my system, though!

Anyhoo, was playing some Kingdoms of Amalur and Devil May Cry last night. Both running maxed out at 2560x1440 at 60fps solid is a sight to behold. :D
 
Has anyone gotten his/her hands on "the new" 3DMark? Please post your scores, especially Fire Strike and Fire Strike Extreme.

I tried it yesterday with standard clock speeds and latest beta driver, but wasn't able to retrieve the results, maybe a bug in 3D Mark Basic. The FPS in Fire Strike were rather low (unlike the other 2 tests), below 30 and sometimes even sub 20, but that doesn't have to mean much I would think. Ice Planet runs over 1,000 FPS and Heaven's Gate over 100 (only the physics test had problems).

I'll try again later to see if the results page works now.

I also tried the Crysis 3 beta yesterday, runs well in High with FSAA at 1440p. No idea what the frames were, guess I'll have to install Fraps.
