Averaging 1270 seconds on the windows box, 1180 on the linux box. Screaming right along!

Averaging Temperature of 100C on my Haswell processor.

I'll be delidding my 4770k at the end of this month.

The January GFN challenges have been finalized. We did a pretty nice showing for these hefty units.

I would ask you if you are using a reference cooler, but you know about delidding so I assume you have something decent. Is it overclocked? I found haswells running avx apps have temps that go nuts when overclocked and the new llr app uses avx and avx2. My 4770k will run at 4.4Ghz until I start hitting the avx stuff hard. Then I don't like going over 3.7Ghz. Even the temps are a bit high. I leave at stock speeds unless I know I'm avoiding anything along that line for a stretch. I'm actually going to liquid cooling soon but that's mostly for the gpu. The 4770k also draws mad power when using avx. TJmax for haswell is 100, it should be throttling itself if you're hitting temps that high.

I run stock on all my CPU/GPUs. I do run 50% cores with HT on in the BOIS for LLR.

Less than 3 hours to get your PPS-LLR in for the challenge. Our team has been sitting at around position 14 for most of this challenge. We would need a good hit to move up a spot or two, but we could be easily caught and move down. Hustle those cores (well do what you can)!

Non overclocked 4770k (well, 3.8GHz).
I have a combo watercooling kit for both CPU and GPU. The GTX580 is not getting hot at all under full load, but the Haswell is boiling.

I couldn't go above 3.7 without having to bump up the voltage regulator. If you aren't hyper threading though you shouldn't see a full blown 100 degrees. Might want to redo your thermal paste.

I was hyperthreading and using 7 cores. (1 core reserved for Majestic client and 2 VM's)
I had redone the thermal paste already but that didn't help.

Hyper threading explains it then. hyper threading and avx don't play well together. Drop it down to stock speeds and your temps should come down. Some. Try turning it off. You'll actually finish more WUs in a time period with HT off than on. You can do the 50% thing, but you gain more if you turn it off in the bios. There might not be anything wrong besides that. Though you may want to check your voltages when the LLRs are running to see if it's maxed out. At 3.8 running these it might be. I think I only got mine to 3.7 without hitting the ceiling or raising the voltage regulator set point. It kept getting close to 1.4v and you don't want to do that on air, which I currently am.

Mine is set at 1.2V iirc.

I need to reserve 1 core for other activities besides CPU crunching. If I would use all cores the Majestic12 client's error rate goes up. With HT off, that would mean 25% and with HT on only 13% of the processor is sacrificed.

Then again, de-lidding sounds interesting as a performance boost.
I have some good thermal paste and even a 25 micron sheet of pyrolytic graphite I might want to play with. (Someone misplaced the sheets of Indium foil which would be more awesome to experiment with)

Good luck then! Just remember delidding is also like the silicon lottery. The tim inside isn't bad stuff like a lot of people think. You may gain nothing and run the risk of killing it completely. You could try a more robust cooling system. #ni-2

AVX and AVX2 have steep advantages on this. Best if run with HT off

Just my luck to get a semi-heatwave this week in Holland.
The Haswell is already overheating with max 6 cores doing Primegrid units.
I might underclock during the challenge just to get some work done.

First 20 downloaded and running. Let's hope for good luck this time around (IE not having a machine go nuts) for me.
