8600M-GT successfully overclocked

I Overclocked my 1720!

I overclocked to 500/1000/430. It's such a rush type feeling seeing as it's my first time doing it.

I turned on Crysis immediatly, and played for 2 hours or so before my game stopped responding as it saved lol. The game runs noticably smoother, and my GPU temp didn't seem to go over 63 degrees - This is good right?

Do I have anything to be worried about? My laptop is on my desk with no cooling pad under, is that something I should invest in?

But the results are phenominal thus far!

 

If running Crysis for 2 hours only got you 63 degrees... that is one CRAZY cool overclocking. Are you sure it didn't drop when you quit Crysis? Were you monitoring during gameplay? If so... man, that's wild. I overclocked my 8400GT GDD3 to 550/650/ and it gets around 74 in Crysis, CoD4, and UT3! Still cool... but not that cool!

 

Yea, I had the moniter in the top left hand corner during Crysis. It shocked me too, but not so much because before I OC'd I don't think I broke 60C.

It's 50C right now idle.

The Core temp is what I should be monitering correct? just making sure lol.

 

Ahh...the first overclock. Congrats on that! I'm very confident that card has much more headroom than 500/430. It's the first step though, if you have any questions feel free to ask!

 

I don't need to invest in a cooling pad do I? In Rivatuner settings, im viewing Core Temp, that's what I am supposed to moniter right? And what is the limit degrees wise before I should worry?

 

My G1S with the 8600 gets to ~95 regularly. You are fine.

 

Cool thanks. I just pushed it to 520/1050/450! Hehe

 

I believe your timing is off. Doesn't it need to be 520/1050/525. Correct me if I'm wrong.

525 is very high for memory, the highest stable clock I have seem is 500 for the DDR2 version of 8600m GT.

 

What he said, the stock is 375 I believe.

So with my current OC settings im getting still nothing over 63C in Hellgate london (Still playing).

These OC settings are really good though, I finally have Very High Shaders and Textures on! In 1440x900.

 

Ok, sorry... I thought it had to be half of the other clock. My fault.

My GDDR3 8400GT memory is clocked at 650. Why such a difference with the 8600's? (Dumb question I'm sure)

 

Not really sure there, but DDR3 is more powerful than the DDR2 so that could explain the differences between OC'ing there.

I have a question though, if my Core Temp is constantly near 64C while gaming I;m perfectly fine right? And don't require anymore cooling? I'm just nervous heh.

 

Because 8400 GT has GDDR3 memory therefore allowing it to be clocked higher. Additionally, 8400 GT is weaker comparing to 8600m GT thus the higher clock makes up for the lack of stream processors. 8400s all have only 16 SP, while all 8600 have 32 SP.

 

Let's fine, people with c90s asus have alot higher temperature than your card. Just make sure you understand that OCing can cause manufacturing defects to appear faster and it is a risk you have to take if you want to OC. Some cards will not demonstrate any problem through out it's life time, some will show very soon, so it all depends on how the card was made.

 

Oh I know the 8400GT isn't as powerful as the 8600GT, just wondering about the OC'ing. Thanks for the info. I'm still VERY happy with my 8400GT! Had an 8600GT before, but kept getting artifacts, bad performance, and just straight problems. Returned it, got my money, and bought my Vaio!

 

Would it void my Dell Warranty?

 

OCing? yes, but if it is just driver OC, just remove the Ocing software before you need a replacement, Dell usually doesn't care about these stuff anyways. They will never know.

 

My Toshiba SLi1's stock clocks are 475/950/702 [DDR3].

I run an oc of 555-565/1130/837. I've boosted it to the 8700m's clocks, but to minimal performance increases in real gaming.

Just keep an eye on your temps with oc's on a game by game basis, benchmark it for an hour to get a good sense of each games demands. For instance, Painkiller without an oc gets hotter for me than Oblivion with one. I've heard many say they get into the 90s, but I prefer to keep it under 80c just to be safe.

That my card are on top of each other doesn't help matters, a good fan cools the bottom card and keeps the fan off while the top card's temps rocket up.

 

Just pushed it to 550/1100/475...but i'm nervous that it'll end up killing my GPU quickly.

And let's say I wanted to revert back to stock, I could just hit default in Rivatuner and uninstall it and my settings would be back and stay at default right?

 

Just unchecking "Enable driver-level overclocking" should get rid of the overclock.

 

What is a safe overclock in terms of frequency of 8600m GT, and temps? Is it alright to keep an overclock 24/7, what's a safe 24/7 overclock in terms of temps/frequency as well. Is it better to just set on an overclock before gaming? And if so, can the temps/frequency be a little higher?

 

I switched over to Ntune and pushed my OC to 600/475. Got a 4105 in 3dmark06 and the stress test for 30 mins said 116 passes complete whatever that means.

Going to try some games.

As for your question, I really don't know...I just put a book in the back of my 1720 to prop up the back so the bottom fan get's some air lol, seems to work actually.

Going on the topic of Ntune, is there a way to display GPU heat in game?

 

Not sure about ntune but rivatuner does.

Seems to be stable now at 630/1260/500. No artifacts in game nor going over 63C it seems in games.

 

Please explain what those numbers (630/1260/500) mean.
Which is GPU clock speed, which is the memory speed?, and please explain what the 3rd number represents.

 

(630/1260/500) = (GPU Clock/Shader clock/Memory)

 

What OS and Drivers are you using? OC tool?

 

Is it safe to OC a Laptop GFX Card

 

Also, if you have a hardware issue that is not hard drvie related Dell will ask you to remove your hard drive before you send it in So they can not detect it, if this remains true.
