I just overclocked my 3700 from the stock 2.2GHz to 2.53 at only 230MHz FSB. The temp is pretty cool at 35*C at an idle. I'm extremely happy with this.

Do you guys think that on stock cooling I could get it to 3GHz safely?

Soon I'll be investing in a Big Typoon to cool this thing so that I can run higher frequencies, but for now, will stock cooling be enough to cool this thing under load at 3.0GHz?
 
I'd wait till you get the BT before trying 3ghz, you might not be able to get it at all anyway dont get your hopes too high, but its fun to try :)
 
I know with the 11x multiplier it will only go to 2.8. I wonder if I drop the multiplier and raise the FSb it will get to 3?

What speed do you think would be safe on stock cooling?
 
Hard to tell what you will be able ot do until you get their. I had the big typhoon prior to moving to liquid cooling and it did a pretty good job but couldnt keep the temps down while under a load. It would jump by 10 to 15c while under load. Now that I have water the flucuation is only about 3 to 5c.

The Big Typhoon is a bitch to instal as it seems no thought was put into that part. You cant put any tools under the heat sink to secure it down. You will also need a wide case for it as it came to the edge of my Case when I had TT Xaser. Check out cooler master hyper 6 or the Thermalright XP-90 aluminum or copper120mm cooler.They are esier to instal and have identical cooling to the typhoon. The Thermalright doesnt require you to remove the MB, the other 2 do.
 
it doesnt matter what speed you can get it to on stock cooling, its the temperatures from raised voltage that will limit your overclock. I got mine to 2.8 on stock cooling, but it was getting hot and its going to be summer soon, so thats where I stopped.

Yep, for extreem OC you should be using water.

No I meant dont be so sure your cpu can do 3ghz at all, much less 2.8.
 
Well, I bumped it up to 2.8GHz and its runnign very cool at 34*C at an idle. I am extremely shocked at these temps especially since it was 35*C at 2.5. Right now I'm going to go play Oblivion and check the load temps.

I have to say, this procesor comes with the best stock cooler I have ever seen.
 
No, I haven't what is it? Where do I get it? I was looking for a prog like that and couldn't find one.

Load temps hit 45*C while playing Oblivion. Pretty decent I would say.
 
Thank you for the help. I'm going to bed now and I'm setting up Prime 95 to run before I do. I'll run the small test tonight and maybe the others tomorrow. Thanks for the advice and the linkage.
 
I ran Prime95 for under a minute and it failed due to error. I don't quite get it because the system seems very stable. I'll keep it at 2.8 for a few days and see what happens.

I'm purchasing a Thermalright from a trader on the forums so it will drop even more from the current 32*C.

If Prime95 failed with errors, what does that mean? What is going to happen if I keep running it at 2.8GHz?
 
system crashes, program crashes, you name it. An unstable overclock can lead to lots of wierd things happening. Check out the A64 overclocking guide if you haven't, its a sticky in the AMD section of the forums. You'll need to increase your voltage until it will run P95 without errors for a few hours. Or decrease the clock, one of the two.
 
You could try fubaring with your voltages, RAM timers and a RAM divider. Any of those could be causing your problems. However, voltage is a dangerous territory to walk into if you don't know what you're doing.

Yeah, it makes me a bit nervous especailly with this new expensive processor. I'll look into some threads on it and some guides before I try anything. For now, I'll change it back to 2.5GHz and wait till my thermalright XP90 gets here. When that comes, I'll start changing voltages.
 
I think what krameriffic was saying is that putting too much voltage to your processor can damage it from overvoltage, not just heat. Putting a huge shiny heatsink on it wont make it any safer to put lots of voltage through your processor. You should get a better heatsink if your temperatures are too high for you liking at the voltage required to make your clock stable. Most people agree you shouldnt put more than .2 volts over stock to your processor long term without possibly causing some overvoltage damage. Whether or not thats true, who knows.
 
Increase the vcore settings.

Mine is 24+ hours stable at 256x11 - 2816mhz on the Asrock 939 dual sata II, vcore of 1.45V, temps at load 38 - 39C with stock HSF.

Most of the 3700+ SDs in the Eclipse's DB thread here hit 2.7 - 2.8 on air.
 
The max voltage that the 3700 will allow is 1.450V. Thats only .05 over stock. Nowhere near the .2V you said.

I am going to wait for the Thermalright because I don't want the increase in voltage creating unhappy temps. (I like to stay low 30's at an idle :D ). Once I install that I'll try the core at 1.45V.
 
Did you try setting your HT to x3. Also, may want to bump up your ram voltage as well.
I would start bt setting HT to X3 and start clocking it down a bit at a time untill you get a stable OC. Once you find were you are stable at your setting you can then push it a bit at a time increasing the voltages as needed. It takes a few days but it's worth it.

You have to solder two contacts on the board to allow higher vcores (ive got the same motherboard you do). If you fail prime, it means your cpu isnt stable, it might seem stable, but its not and you dont want it crashing later when your doing something important.

Hey, I'm all for the overclocking, but as far as soldering goes...no way. I don't feel like ruining my stuff, I paid alot and don't have the money to spend if I break it. I'll pump the Vcore to 1.45 and see what the temp are like on the stock cooling just because now I don't feel like waiting for it.

I'll run Prime95 for a while before I go to bed, and if the load temps look ok, I'll let it run for the night.
