Windows 7 - Stress Test

Hey

I was running some tests on my computer to see the Min-Max temperature , so i wanted a good program that stresses HD, Ram, GPU and CPU. Just like ORTHOS ( But orthos only stresses CPU And RAM ).

Oh, and is it possible to Undervolt GPU's? ( I think it is a dumb question, but..).

And if anyone know cooling solutions such as Undervolting, please post together with the program.

Hi for the stress tests your best bet is to use 3dmark you can get a trial version from Futuremark

The 3dmark test would put most stresses on the CPU and GPU. However the CPU and GPU should be the only real producers of heat in a system. The Ram should produce only minimal amounts of heat as should the hard drive.

As to the second question about undervolting GPUs yes it is possible. I only know from an Nvida point of view but the both Rivatuner and The Nvidia Bios editor would help and the process is mostly overclocking in reverse. Reducing core voltages and then testing stability, you may need to change settings to lower the performance of the card to accommodate the reduced voltage.

Are you worried about temperatures and if it is the system in your Profile be aware that laptops usually run pretty hot. Are you experiencing graphic errors or shutdowns due to overheating?

You obviously have never used FB-DIMMs . But normal DIMMs, yeah.

No, i am not experiencing any Shutdowns, but when it reaches a certain point, the GPU is so hot ( ) that it decreases the core from 600 MHZ to 200 MHZ to reduce heat. So i experience LAG.
And Undervolting is not the same as Underclock. Undervolting doesn't affect Performance at all, so thats why i wanted to know.

I do know the difference between overclocking/underclocking and overvolting/undervolting.

It's just that I've been unable to decrease the voltage of graphics cards much without having to reduce the core clock and shaders at the same time to avoid artifacts, but I was using a different graphics card from the one in your laptop so hopefully you will have better luck

The main reason I posted about decreasing those settings is I thought you might have been having problems with shutdown and undervolting the card by a large amount might greatly reduce system temp.

It's also possible that my definition of undervolting is completely wrong

But for me undervolting would be decreasing the core voltage of a system while maintaining performance or increasing it example my CPU is undervolted to less than stock volts but also overclocked to an increased clockspeed.

If I'm wrong about undervolting then please correct me.

Either way those programs I linked can certainly change the voltage given to the gpu and edit clock and fan speeds if needed.

Complete system stress......


Run the power supply test if you wanna bring your rig to it's knees.....

SiSoftware Sandra has an inbuilt burn test and is also quite usefull for finding hardware info.
SiSoftware Zone

Everest Ultimate has a stress test that maxes out CPU, mem & cache.

Sounds like your GPU is throttling down from too much heat, "a common problem in the summer time".
If you are seeing too much heat into the GPU most likely you don't have enough case flow. Adding case fans goes a long way towards fixing those types of problems.
