Trying to overclock video card...

I'm trying to overclock my video card...except when I do...and I reboot...the sliders won't stick. It just goes back to the default clock settings. Why is this?

I'm using nVidia's nTune software.

On the other hand, I used Rivatuner and it worked. Anyways, I overclocked my 8600M GT to having a 550Mhz Core clock speed and an 800Mhz Memory clock speed.

The factory settings were 475Mhz for the Core, and 700MHz for the memory. Is this safe?

I mean my games are stable now, if I had the Core at 575MHz, my games would bug out, my video driver would stop working, and I'd have to reboot. But now it's 100% stable, and the temperature is around 80 degrees Celsius when idling, and when gaming it barely hits 90 degrees Celsius.

Theres no reason to overclock your laptop.

Edit Good god 80C ? I idle at 42C

And I doubt your computer is stable when you really don't know what you're doing.

Run Orthos for around 12 hours

Yeah, even when it wasn't overclocked it was idling like at around 76 - 78 degrees Celsius, lol. It gets pretty hot.

Edit Nevermind. I just turned my laptop on...it's idling at 71 degrees Celsius right now, lol.

Is this that ASUS you were creaming over? You already said you probably won't push it to spec, so why are you considering an OC? Is there some game that will really benefit that much?

It's a laptop, I'd be careful about overclocking. O/C'ing is great for desktops, but not really suited for laptops. They aren't well ventilated, and the excess heat produced without adequate ventilation will likely shorten the life of the components AND void your warranty. Laptops are manufactured to operate within much tighter specs usually, without a lot of headroom.

To test stability you could stress test it with several hours of 3DMark06, but honestly I wouldn't bother.

80 degrees?!!

I don't know about video cards, but the CPU auto-shutsoff at 75.

75 is high for most CPU's nowadays, but I don't know about shutoff.

Modern GPU's run hot though. The default thermal shutdown for my 7800GT CPU's is 115C, they normally run around 75C under heavy load, around 55-60C idle. My Northbridge chipset runs around 70C and even higher under load. And this is in a full tower case with lots of cooling. It's not hard to imagine 80C in a laptop where cooling is never optimal.

So do you recommend I put it back to the factory clock settings?

Yes


I have my dual core over clocked from a 1.8 to a 2.5 stress tested on orthos for about 9 hours stable, memtest95 stable for hours, messed around with the pefect settings for days

Finding the highest fsb, best mem timings, mem dividers, htt, volts, etc

Over a desktop not a laptop, plus you have such a new and powerful computer you have no need to overclock it

Would it be at all possible in the near future...to upgrade my video card inside my laptop, if so...how would I go about doing that, (it has a PCI-Express slot, and where would I buy a laptop GPU?)

P

I'll probably lower the clock frequencies. (

PCI-E is for Wi-Fi and a few other devices. For a video upgrade, the laptop would have to have an Axiom or MXM card to begin with (similar to PCI-E). That, or be on a separate daughtercard that is connected to the main mobo. (Not likely, but sometimes upgradable in a limited fashion)

^...what? PCI slots are for Wi-Fi and a few other devices...PCI-E is for graphics cards honey. P

Also...I was reading this http//forum.notebookreview.com/showthread.php?t=131334

The first post. How the hell did that guy overclock THAT much on the graphics card and saw barely any temperature fluctuation and had a dramatic increase in speed/graphics capabilities in the games? He had such high frame rates in all of those games...look at CSS ... 140FPS? O

I'm getting 60 FPS @ 1024x768, and 30FPS @ 1680x1050. (

I tried overclocking my card's core to 575Mhz+ and the card crashed on me when I did those performance tests in the games. The screen would get all fuzzy and it would explode. How the hell did he do that? I mean he's showing you the results right there...also...it's a less powerful card too what he has. He was using the 8600M GS and I have the 8600M GT. Why do things always fail for me. (

lisobli I wish I could achieve the same overclocking capabilities as that guy from that other forum.

In a desktop. ;)

Are you asking for advice on a desktop, or a laptop? Laptops use a mini version of PCI-E, but as I said (shoud've been more clear), it's for Wi-Fi and other devices (Turbo Memory etc).....[ic89f524811]honey[/ic89f524811]. lol

Again, are you really [ic89f524811]seeing[/ic89f524811] any benefit, or are you just wanting to get the most out of what you have for the sake of it? I used to be that way, but a fried card taught me a lesson long ago. )

PCE-E is for a lot more than just video, even in desktops. You can buy PCE-E network cards, sound cards, drive controllers, etc. Video cards just happen to be the most common in consumer equipment.

60fps in CSS isn't bad... I get about 3fps on it... ? Source is stupid because the headbox isn't on the picture of the head, and being able to move stuff is stupid.

Just leave your computer alone ....it won't be worth frying anything.

WOW! Overclocking is NOT for notebooks, they are very ill equipped to handle this kind of extreme heat. They do not have nearly the cooling efficiency you get on a conventional desktop PC. Now with most desktop graphics card 80-90 celsius is pretty out of spec. Since it is a notebook I'm sure it can withstand slightly higher heat but still, the risk vs reward on that is not worth it. If you wanted extreme gaming you should not have gotten a notebook. I would say put it back down to stock in my opinion. 90c will burn your nuts.

Word...I mean you should see my heat sink and cooler on my cpu and i'm pulling like 4-5 fans in my desktop to keep it cool.

?

I would just like to know how this person achieved this much overclocking capabilities.

Come on now, let's not start asking reasonable questions.

Those were his temperatures. Maybe you should try to get those temperatures and then overclock.

Please. I'm just curious as to why I cannot achieve that just as easily...because it won't work for me. If I overclock too much, I get artifacting and my games bug out...drivers die, and I have to reboot. (

For instance, why is it with his less powerful card, he can enable 16xQ CSAA (AA), and I can only enable up to 8x MSAA (AA), in Counter Strike Source. Otherwise, if I go anything above 8x MSAA, the game bugs out and weird objects start appearing on the screen. (

Dude, overclocking is not an exact science. Two different people with identical hardware will entirely likely have different results -- sometimes drastic. Different CPU manufacturing codes O/C better than others, and that's within production runs of the [i442b97c1c1]exact same CPU model.[/i442b97c1c1] Same with any other IC's, to include RAM and GPU's. Not to mention temperature profiles.

Like we said stop trying to O/C a brand new laptop. You're going to cook the thing and void your warranty, and for what? You already said you weren't going to hardcore game with it (of course not, it's a laptop), so you have no real-world benefit to gain.

I get a kick out of O/C'ing stuff, it's fun... but not laptops. They're not made for it. You've been told this over and over and you keep posting the same questions. That's probably why people stop answering you, or otherwise flame you. You really do bring it on yourself, you know.
