Most of the reviews made some mention of it, and it was always clear that they either thought it wasn't supposed to do that, or it was simply annoying to them.

I, for one, am looking forward to having that feature. I need it.

Thank you, Choggs. You're very helpful. This is why I came here.
Hehe.

Always glad to help out a fellow Minnesotan. Keep warm! It's -1F here right now. If I shut the door to the room my computers are in, I don't even need to turn on the heat on sometimes!

Fellow Minnesotan? No wonder you're so awesome.

So, -1F? Wow. Where are you, approximately?

hehe hot computers!

lol

As for locale: central. A considerable drive north of the TC. My little temp gauge on Vista's sidebar says -1F, it's usually pretty accurate.

My sig rig + an AMD Athlon XP rig get pretty dang hot when they're both running.....

On an off-topic note... Congratulations:

If you have trouble overclocking your CPU or GPU after upgrading your videocard, you probably need a new powersupply. I found this out myself first hand after many many trial and errors. It was either my Mobo or my powersupply.

I hijacked my buddies for a few hours and everything ran great. I use my cheapo 450watter and the higher I overclock, the more unstable everything becomes. Note: Everything was running fine till I installed a powerhungry videocard. (power hungry considering what I was using before heh)

you can easily overclock a 128bit card. I have an old ati 9250 that uses a 128bit memory bus. it overclocks from a stock core of 240 up to around 290-310 (depending on game) and the memory goes from 200mhz up to a good 220mhz without problem

While I'm not disagreeing with what anyone here has said, I would point out that BASICALLY a pre-overclocked 8600GTS is going to be about as fast as *that* particular card is going to ever get. They aren't good overclockers at all, cause they already run at a very high clock rate, and get very hot with their crappy stock cooling solutions. And I would also say as a very *general* rule, the gains one would see from overclocking a 128-bit memory-bus card would be relatively minimal, especially with newer games at higher resolutions/IQ's.

factory overclocks are not always maxed out but rather a marketing gimmick.

lets say I have two cards. one stock at 600mhz the other factory oced at 620mhz. card a is able to clock up to about 650mhz lets say. card two should be able to clock right up around that same range also. just being factory overclocked doesn't change anything.
the difference is rather then you adjusting it in atitool, rivatuner, or other software based overclocking ofy our choice is that it overclocks it in the bios.

While I see how you are speaking 'generically' here, and what you say is *nearly* always correct (assuming you mean 'two of the SAME cards'), but in bringing up the point you make, it seems maybe I must've been unclear.

I'm speaking of a specific card ... the 8600GTS. This card, even stock, is near it's top clock speed. Thus it is not typically a 'good overclocker'. Buy an OC'd version, you will be even CLOSER to it's top clock speed. And indeed, what you say is true, the top speed should be the same regardless of whether the clock is pre-overclocked or not. But as a '% change from original' (as opposed to 'reference' ) clocks, the pre-OC'd version is likely to be an even 'worse' overclocker.

I would say, though, that I have definitely experienced exceptions to the 'rule' you are stating. This is because, in the cases of certain cards/manufacturers, the pre-OC'd versions of the cards utilize a higher core/mem voltage than the 'vanilla' versions.

The evga 8800GTS 320 SSC appeared to me to be an example of such a card. I started out with a vanilla version, which I later upgraded to the SSC, and my overclocks on the SSC went CONSIDERABLY higher. I know, small sample size, but I know for sure such volt raising is done on OC'd cards sometimes. But I don't believe the 8600GTS was such a card.

^ I've seen "factory overclocked" cards overclock to higher maximum frequencies than "stock" reference boards. Sometimes it has to do with increased voltage. This isn't always the case though. It varies card to card.
