Intel and Prime95 v23.6

[eva2000]

interesting what Intel requested to be changed for Prime95 v23.6

interesting comment whether true or not that Intel's been using Prime95 as one of their tests to do hmmmmm

Using Thermocouples and Thermal Meters

Thermocouples provide accurate temperature measurements if properly placed and carefully routed. Thermocouples and thermal meters can be purchased through electronics supply catalogs. Some Digital Multi-Meters (DMMs) provide a thermocouple input and are able to function as a thermal meter.



Figure 2. Digital Multi-Meter with Thermocouple Attachment (Left) and Thermal Meters with Thermocouple (Right)

Evaluating the system thermal management around the desktop boxed processor can be done by taking an air temperature measurement of the air entering the fan inlet, or by measuring the temperature of the heatsink base at a specified location. Refer to the thermal management document for the specific desktop boxed processor for the recommended location for the temperature measurement and for the specific values for the fan inlet temperatures and heatsink temperatures for each processor speed.

A simple way to test these temperatures involves placing a thermocouple at the desired location and reading the temperature values from a thermal meter after the system has been running high power software for a long time to simulate the worst case system load. For fan inlet measurements, it is recommended that a single thermocouple be placed exactly 0.3 inches above the center of the fan inlet. For more reliable measurements, using four or five thermocouples equally spaced above the fan inlet would allow for an averaged inlet temperature value.

Be sure that thermocouples are not in contact with or near any other heat dissipating components in the system (like the hard drive or graphics card). It is important that the tip of the thermocouple become the same temperature as the desired test point. Any undesired heating of the thermocouple wire could cause the tip to be warmer than the test point. For air temperature measurements, it is most important to route the thermocouple out of the system without any contact to heat sources. For temperature measurements of metal surfaces, it is most important to have a good contact with the metal surface and to have sufficient adhesion and bracing (to prevent the thermocouple from dislodging during the evaluation).

Wow, wouldn't that be pretty useful? Options asknig you what to stress a lot...

eva2000 do u know if it it stress HT cpu's without having to open it twice?

Thanks m8! I'll wait for your update... :)

Thanks for the heads-up. Interesting.

Any news on HT and prime95 v23.6?

Where can I get 23.6? I only see 23.5 on the main site.

There was talk aout a gltch with possibly lasat version of prime and INtel c1 stepping chips and new p4 c chips....Any truth to any of this and maybe does the version 23.6 take care of those.....

The only glitch I have seen is that prime95 stop being the true test of stability and often would run for a day to crap out in a handful of other thought to be less stressful programs...

Jhites...thanks for the link....

Jhites...thanks for the link.... the talk about glitches in prime95 have been around for a long time but whether there's any truth to it has never been proven
