I was thinking about those stress tools, they all claim 100% load. But the temperature at full load is different, so they must use other parts of the cpu or gpu to get that full load. In other words, can there be a 'ultimate' stress tool?Cryect said:Now how much useful stuff you can do where you can have all the units active is more questionable but I'm sure there are plenty of tasks where its all quite useful.
Heh, yeah of course its possible with specially written assembly language designed to execute instructions in a way to use everything at once.

I don't think NVIDIA has a T&L pipeline in the NV4x anymore. They did in the NV30/NV35/NV38 iirc (and not NV31/NV34/NV36 too, but that's just iirc again) - but there is NO evidence that there is one in the NV40 anymore. My guess, thus, is that there isn't.Scali said:With GPUs I don't think it is possible at all, especially with NVIDIA's hardware, which has multiple pipelines. If you use the shader pipeline, you cannot use the fixed function pipeline at the same time, for example. So some units are just mutually exclusive.

Although the CPU work is divided into these components sequentially (at least in non-hyperthreaded CPUs) so all the components of the CPU are not really used all the time but in a sequential order, it gives me the illusion of 100% CPU load in all its components.

What programs do you use for that? I've been wondering about how to stress test the various aspects of my parents system to find out what is causing the spontanious memmory dump/reboots. I tried Prime95 and 3DMark01, but neither caused the crash, though it does so very frequently in general usage... though I was running them seperately? Should I run them at the same time?
Oh, and sorry for the off-topic...
