Help testing a specific core

[Garido]

Basically I'm concerned that a Core 2 Duo I have lying around may be developing a fault. When a load is applied to the 2nd core (100%) the temperature will not budge. I find this strange despite being under water. Furthermore, when the first core is under load and the 2nd one isn't, the temperatures reflect that.

Is that any way of accurately testing the 2nd core and only the 2nd. IBT only tests all cores rather than allowing for individual core testing.

Hey mate,

Some of the core2's had sticky temp sensors? The machines at uni suffer with this. Could be that? What cpu is it?

if you use a program called winlauncherxp you can set it to run IBT on just one core, might help you do so.

Sorry dude, it's a E6500 which is in my sig. I keep saying this as I had a Core 2 Duo exhibit a similar problem. Apparently Prime95 has a way of testing certain cores so I'm giving that a try now and will give results.

Hey mate,

A quick google of e6500 stuck sensor pulls up loads, heres one such article

open task manager right click a process and select "set affinity" it lets you pick which core(s) a program can use

Some quick results here. When the test is run on the 2nd core and only the 2nd core, the difference between the temperatures on each core is varies from 2 to 3 degrees.

When the test is run on the 1st core and not the 2nd, the difference is greater, 8 degrees, maybe even a bit more. So far I haven't blue screen or gone over the recommended temperature of 73c but it's quite strange

Testing worker 1 (1st core)
Core 1 Temp: 52c - 0% load
Core 2 Temp: 54c - 100% load

Testing worker 2 (2nd core)
Core 1 Temp: 58c - 100% load
Core 2 Temp: 49c - 0% load

Waterblock is mounted quite tightly and is very snug. Idle temps are about 37c and full load temps with Intel burn test are 67c.

Thanks for the link. That link would explain why I've never seen under 37 despite having water. My only concern with a stuck sensor is that it doesn't give me confidence in the rest of the sensor.

Cheers for the tip. Trying it now.

The two cores are never going work at exactly the same temperature.

You don't need to worry about the stuck sensor. Once the temperature goes over what ever it's stuck at it works fine.
