Higher Clock speeds, LOWER temps??? I'm confused

Just noticed something unusual, thought someone may have an explanation.

Asus G2S (see sig for details) on stock clock speeds on 8600gt, 475/700, I see about 70C at idle and high as 95C under full load using nVidia NTune. Yes, sounds HOT but never had issues and believe its normal for these notebooks.

I just downloaded 3DMark06 and scored a 3996 (good?) on factory clock. Was curious to see what a little OC would do for my 3DMark so changed to slight increase at 512/740. 3DMark 4239...sweet. Lets try some games.

Logging with nVidia NMonitor, highest temp i see now is 92C, averaging between 89-90C under load. Any help/suggestions would be appreciated. Thanks.

 

Thats not to bad. Maybe your fans are spinning up a bit more? I'm not sure how the G2S works with fans.

I have my GDDR3 8600m GT clocked at 550/825 and I hit just above and/or around 4.8k in 06 @ 1280x1024. One thing I've found out though is the card's thermal throttling kicks in moments after hitting 96C, so if your playing and you notice your FPS gets docked in half, you might be to high, however, 512/740 isn't much. And yes, 3996 on stock clocks is good, in XP with 167.68 I hit just above 4k as well.

 

The fan is running more.

Although this kind of overclock shouldn't have a big effect on temps. I'm pretty sure you can push it to 560/850

90-95 is an okay temp

 

^As long as its stable and not artifacting

 

Cool thanks for the quick responses. if the explanation is due to increased fan speeds, then i guess 90-95C under load is an acceptable range. i played with 3DMark a little more, OC to 550/833 scoring 4553 which i guess is pretty damn good.

another question i have is using NTune, i change my clock speeds, which is also displayed on NMonitor. If I increase the speeds anymore from where they are they are displayed in red, which means "bus is operating outside an acceptable tolerance and may suffer damage". So is this as far as i can go? Or am i nearing that point? Thanks.

 

Can i see this visually, or do i need something like ATI tool? I read somewhere OC speeds of my card and tried the same overclock and my display started getting all fuzzy and screwy during 3DMark, thought it was gonna blow up I immediately exited the test and restart my computer. Thankfully I didnt do any damage....i hope

 

It's just a software overclock therefore unless you left it to overheat, there shouldn't be any permanent damage.

 

It said that because the PCIe Clock was very far out of sync. It has become apparent to me that a lot of laptops don't have this lock on them. When you OC your video card aparently your motherboard increases this clock...I'm not sure if nTune is causing this. You might want to look into ditching nTune (Not Recommended IMHO) and grabbing RivaTuner. This might fix your problem :]

You would see artifacts visual. ATiTool comes up with artifacts out of nowhere sometimes to be honest - and not to mention the horror stories I have heard with it. Yeah, those are artifacts, it looks like rainbow snow for one example, or lines or polygons getting extremely distorted. You didn't hurt anything though, but you've hit the limits of either your core clock or your memory clock. To much heat + to high of clocks = crashing/artifacts/instability. You didn't do any damage, don't worry
