OC'n my Core2Duo 6400 Conroe

[Panda Man]

Its a synthetic benchmark, don't trust it. Go by frames. And just prime it for stability about every 50MHz or so, run 3Dmark and see how its doing. A 10MHz bump won't show much.

Also, double check to make sure its not heating up and throttling, check and see if you have an option in the BIOS to alter the temp it throttles at change it to 60C

So I think its probably the temp monitoring software that slowed it down? I also forgot to close all programs that I didnt have running in the background in the other benchmarks..... which is steam and pcbackup client, which is about 29mb of memory.

I'll run it again now though, after closing those progs

[edit] Hmmm.... Well it just went down to 5741 3d marks....which is the same score that the stock cpu got... I don't get it. it shows it as Intel Core 2 2.29 GHz which is what I set it to, but it underperformed.

Weird... I'll do more tests/oc'n when I get home today and tomorrow and keep posting....

Quit being a girlie-man and OC the crap out of it:) Use speedfan to watch temps. 63C is max temp you want to run for sustained periods of time. Get this program to run for stability testing.
Download Stress Prime 2004 BETA

It's built for multi-threaded

Also 3DMark is a video card benchmarking suite, and while at a certain point it depends on the CPU and RAM, I think you'd be better benching with something such as SuperPI (http://www.xtremesystems.com) first to see your relative performance... then go in more specialized benchmarks. ;)

I'm runnin safely @ 316FSB (2.5ghz per core) and it 100%'s (Prime 95 torture test and FAH running on each core) at exactly 41°C. I ran that for about 7 hours today. Works fine ;)

When I get home I'm gonna bump it up to 356 and test that overnight.



ps: Does the temperature of a CPU change instantly? It seemed like the moment I turned off FAH and Prime95 my temp dropped from 41°C to the idle 24°C

You just have a good HSF. No, lol, it doesn't change instantly. Under full load, give it about 5 minutes to see just how hot it will get. It could still increase about 1 or 2 degrees just after an hour of full load.

My 3dMark05 score actually has 2 separate numbers, one is video points and one is CPU points. There is a great increase in CPU points for each 10mhz I go up.

Stock: <-Processor Intel Core 2 2133 MHz
3DMark Score5776 3DMarks CPU Score7567 CPUMarks
+10mhz: <-Processor Intel Core 2 2208 MHz
3DMark Score5800 3DMarks CPU Score7743 CPUMarks
+20mhz: <- Processor Intel Core 2 2208 MHz
3DMark Score5802 3DMarks CPU Score7846 CPUMarks
+50mhz: <-Processor: Intel Core 2 2528 MHz
3DMark Score5834 3DMarks CPU Score8221 CPUMarks

My CPU can render the 2nd CPU test @ 7FPS! Which is nuckin futs, cuz at stock, it goes @ <3fps :)

Look, overclocking is different for everyone....not everyone has to, or wants to push their system to the very edge of stability. I typically run my system anywhere from stock to 20% overclocked....even though it could easily go further if I wanted to push it.......just make sure you are comfortable with what you are doing, and do your homework......people can tell you all kinds of stuff and tell you what to do....but the bottom line is when you break something, they aren't going to pay for a replacement.....you are.

That's a good way to burn up a nice new proc.
You already have a good proc no need to fry it so just a good middle of the road over clock will do nicely. Your normally pretty good until you start raising the volt. The heat is going to be the thing that does a lot of the damage. So be careful with raising the volt. Have fun but don't go nut's you already have a very speedy proc as it is.

I don't believe that SpeedFan 4.31 works with my compy.

Here are the numbers:






That doesn't look right at all....

Is there something produced by Gigabyte or someone that will work correctly?

[polobunny]

Looks right to me. Temp1 is most probably your CPU temp.
A CPU temp will not climb up instantly, it takes some time (more than 5 minutes to heat up Panda) but it will rapidly drop once you stop stressing it.
