Do the core have bad contact with the IHS?

Or most probably youll find that core sensors are miles off the mark and you'll get 1, maybe 2c @ load from removing the IHS and gain basically nothing.

Keeping in mind your lower core idle is actually physically impossible...

I know the sensor there is wrong, as I idle below ambient. However, the fact that it shows 24c difference, and freezes my computer in a second(in contrast to core 2, which keeps on going) convinces me that the IHS is making bad contact. I can't see any other logical thing(?) :confused:

Easy, that core cant cope with those speeds.

When a processor fails to run at a certain speed, it doesent all fail at once, its often just one bad gate.

In my case, my 170 will do 2.8GHz @ 1.375v. @ 1.35v, core 0 (the one with reported sub-ambient idles) fails, every single time.

Yeah, you could be right, I'm not really sure :confused:

Ok, now I'm REALLY confused :confused:

I just tried stress testing core 1 alone, and not core 2 at the same time. And I was shocked! The temperature of core 1 is a lot lower when I'm only stress testing core 1, than when core 1 was idle and core 2 stressed... How can that be? core 1 is actually stable now, until I start core 2 at the same time...

You dont get it do you?

YOU CANNOT TRUST THOSE "INTERNAL SENSOR" READINGS AT ALL.

Thats all there is to say about the matter.

Relax, I get it, but it still doesn't make sense though

Ignore the readings. If the cpu is not stable at stock, RMA it. If it's not stable at your current overclock, lower the clock or up the voltage.

chuck some liquid nitrogen over your processor, if that won't cool it down, nothing will

Bringing this thread back to live

. I just popped off the IHS, and guess what, max 3-4c difference between each core! :eek:

So it obviously was bad contact between the core and IHS. Unfortunately, it doesn't look as if I can overclock any further at all

. Well well, it was fun though

Even with more volts?

Yeah, it doesn't seem to want to go any further at all

. Can't even get it 100% stable at 2.8ghz now...

What's a little odd, is that during idle there's still a big difference in temps between the cores, but as soon as I fire up some load it's more or less equal. However, I do have another x2 3800+ that might be worth removing the IHS from, but I have to use one of them at stock cooler all the time... So if I'm going to remove IHS from my second cpu, I have to reassemble the IHS on this one again...
