Unknown heat problem keeps me from overclocking

[DragonFire]

I have a Asus A7V133 with a Tbird 1.4 being watercooled


For the last few weeks Iv been having system lockups in XP when I was running at 1.53GHz+

I thought taking everything out of my case and putting some new AS II on the cpu would do the trick but something has gone wrong.

In MBM it says that the cpu temp reading is about 113F idle and up to 123F under full load. Now since everyone knows you cant trust the onboard probe, I put a probe right next to the core and it reads about 96F under load.

I really didnt think it was a heat issue intill my computer would start locking up after I started RC5 and my case temp is high to for some reason.......right now its under my window which I have open right now (its about 60F ourside) but the case temp reads 80-82F.

All this is while im running at 1.4Ghz at default voltage.


Any ideas? Maybe I should just get a Dragon Plus and be done with it since I seem to be having problems with this Asus board......sigh

What are your 5V and 12V rails running at idle and at full load?

Also make sure your radiator is always blown out really well and if it was me I would filter it somehow. I use a piece of a home furnace filter and it really grabs all the major dust and doesn't seem to limit air flow through the radiator.

You also may have been running at the very edge of stability all along. What do you stability test with? I recommend the new Prime95 (Run it at 9 priority). It will error condition if your processor/memory is even slightly unstable. And if you run slightly unstable then any slight change in your cooling can effect overall stability and start producing lockups, blue screens, windows protection errors, etc......

The reason I asked about your voltage is that some people have problems in the range your at with their power supplies causing their instability.

Good luck solving your stability issue.

Screw prime95 and folding@home. I could run those programs for over 24 hours with no errors/freezes/reboots with my XP 1600 1.4 @ 1.59. That changed when I tried burnk7.exe (part of cpuburn package) and it rebooted my system after less than 1 minute and it raised the temps 2-3*C higher than prime95 ever could. prime95 is not anywhere as good as cpuburn.

I do partially agree with Rahminator, I use CPUBurn to heat test my cooling solution and my overclock. But I can run CPUBurn for 24hours + with my watercooler and still run, but I can get Prime95 to error condition in the first few seconds. I go with Prime95 stability as the final speed I set for my overclock because it is the lower of the two. I still test with CPUBurn also though.
