~~The GTX 670 Overclocking Master-Guide~~ - Page 243

Yeah, it's suspicous to me too that nobody really seems to hit that... That's why in a previous post I asked what else might affect it, like psu or something.

X58A-UD3R rev 2 with i7 930 2.8 oc to 4.011 ... Precision x max power % is 122% ... It really must be the 4GB Asus.... No biggie cause it really only throttles on overclocks that are above average, though 3dmark seems to be all over the place on gpu clock

Out of curiosity, it 1.175V a safe 24/7 voltage for 1.28GHz on the core clock with a 670? Temps are always below 67C.

unless the bios are borked a 670 wouldnt run 1.175v 24/7. they only pull that much voltage when it needs it, under load.

Well, I run F@H for like 12 hours a day on the GPU, so it is at 1.175V pretty much all the time it's on.

well then, i would say if its running that long at that voltage, its fine. nvidia set the max voltage low to help preserve the life of these cards. long term use, 3-4-5 years may be a different story.

please remember this is my opinion on what ive read. it is by no means fact. it may be fine for the next 20 years. it could die in a week tongue.gif

Sorry double post.

I actually turned my oc off, set to default, including voltage of course, cause I am playing planescape: torment right now.

My temps went down 10~. With my ac on i idle at 29-32 depending on the temp I set on the ac, and with my biggest oc, during planescape it was sitting at 54. With no oc it was sitting at 44, never went above 55.

Voltages presumably increase temps, but why would they increase if its not needed under that load? Gpu clock sat in the 900s (915 maybe, but a single consistent number the whole time regardless).didnt check voltages or gpu use during this game, as it was something I only noticed after I turned the Oc off.

On my OC, my voltages typically only hit max when I am load testing; in most games even at 100% load my voltages rarely go much over 100% in fact, my better card usually sits at 98% power load while my slower one hits 102-104%, at 96-98% GPU load. The top card will hit 118% or so only when load testing. This is at 1215 MHz on 2 670 FTWs. My bottom card will do 1285 stable, but the top card starts crashing above 1215 over like 35c, I like running them at the same speed because I find it minimizes things like SLI stuttering.

from what ive seen with my cards, any 3d load will put the cards at 100% of set voltage.

Actually I left the graphs open and checked after playing some. With voltage at default it was running just over 1.0, like a step up from the default of 0.9whatever. Which it does with max too even like the guide says, max voltage is 1.15 but it runs at 1.175 on heaven (or 1.5 and 1.7 I forget the decimal). So basically we'll call that default voltage.

Gpu usage was ... 1-3. Planescape torment. Yeah, one. CPU usage sits at 24 or 26, something like that. Power # very low too, can't remember. Clock at default 915, which like I said it ran that on both default and max oc.

So the only variable was the 10 degrees temp when the oc is set with max voltage and power % and when it's all set to default offset, 100% power and default voltage.

It seems just setting an OC regardless of power used or voltage or gpu use increases temps. But that's weird because idle temp is still the same with oc on or off, 29-32 depending on how low I set my air conditioner.


Very odd. Also, crap to playing old games with such good hardware. Massive lag during spell casts, and outright glitch during the biggest spells (some thunderbolt just looks like a fat vertical bar of blocky blur colour depending on the area background colour). Also turns the screen black til I hit a button, but that may just be cause you're supposed to die when it hits you. Also, this is my first playthrough so if anyone is gonna comment on this specifically, no spoilers.

Edit: even more odd about power use during heaven compared to others is my monitor actually only does 1600x900. Should my results not me quite a fair bit higher? 1048 with max oc available to me really doesn't seem good... I see way better scores, though most use heaven 3.0 & are using high settings instead of ultra/extreme. At least in screenshots I find.

Sorry for all the rambling in my posts. I'm not exactly demanding answers, more putting things out there for others to stumble & compare themselves. A lot of learning this type of stuff and knowing if it's being done right is this circumstantial evidence from comparison. Sorry if the long posts bothers anyone.
