Perpetual benchmark thread... - Page 24

Sorry I hadn't looked at the link.
The times for less than 8k seem pretty constant as if only one core is used. 8k actually slows down significantly with 16 threads. 8k is probably just the first multithreaded run(i.e. the first test with >16 cores). I would suggest pming prime95 in case he hasn't already seen this yet.

Works fine for me too, but not for the Benchmark.
I'm using a i7-3770 (4Cores+HT) with

AffinityScramble2=02461357

setting using only four cores for Prime. Hence don't touching the HT cores.
That works fine for 2 treads per test by under 10ms/Iteration for 51.5nn.nnn exponents.

But when running the benchmark, Core 1,2,5,6 are used. So 4 Threads on 2 Cores are used.
The Affinityscramble seems to [EDIT] spoil the benchmark. I'll have to comment it out to run it on core 1,,3, 5, 7.

Yes indeed. I am still using my 1300MHz M now. I even posted a benchmark for it in the 100Mdigit thread.

And one more time. This is at 200x24=4800MHz. It survived modest amounts of torture testing in different modes. Temp on TT peaked at 65C with a Cooler Master Hyper 612. I have no intention of doing real work at this speed. I just wanted to see the numbers. The CPU is reasonably productive at stock, and "Summer is Coming." (HT to GRRMartin)

Comparing the last 2 benches there is quite a difference at the same clock rate. The difference is sandy vs haswell. Nice

db597 · 2013-07-07, 17:54

Below are benchmarks for a i7 4770K with DDR3-1866 at 4.3GHz.
Prime95 stable at 1.25V, using a Corsair H110 watercooler.

HWMonitor reports a 141W power draw on the small FFTs torture test.
However, realworld running of 4 simultaneous tests on M6xxxxxx is ~115W.
On my sample at least, pushing to 4.4GHz requires 1.27V to be p95 stable.
At that level, power draw reported is over 150W+!
A bit uncomfortable for 24/7 operation, so I'm going to stick to 4.3GHz.

Was virtually the same on Windows vs linux.

I guess 28.1 will fix that

prime95 v28.1. i3930K at 4.2GHz, 8x4GB @ 1600MHz (DDR3 1600, CL9, 1.35V), Corsair H100. 169 days uptime (we moved). Fedora 16. Built in April 2012, used prime95 and other programs to ensure good overclocking and temps. I love this machine, though it does generate quite a bit of heat when going full bore. I don't like core temps to go above 60C when all cores are loaded.

I use it for lots of other development, not prime95, so I keep hyperthreading on since it's helpful on almost every other application. I'm not going to reboot to turn it off, but I did try setting CpuNumHyperthreads=1 in local.txt (turning it of in the BIOS would be a better comparison). The small FFTs were consistently slower on the 1-thread version, but once past 1024K it seemed to make little difference. On the other hand the 6-core 8192K FFT result was slightly faster with a 10.020 average.

The reason you are struggling to keep below 60C these days is because they aren't designed for that. They are designed for much higher these days. 80C might be a good aim these days. My CPU would die from that heat though(Q6600 G0).

I wouldn't call it struggling -- it's running at 4.2GHz vs. stock 3.2GHz. My 3770K is also 4.2GHz (3.5 stock so pretty tame) and I have it running a little hotter. 60C for BOINC climate prediction, ~68C for Prime95 small FFT torture test. I could go higher but extreme OC isn't as important to me as stability and reasonable power use (measuring with a Kill-a-watt, once past the easy overclocking I saw power use go up dramatically with every small rise in core speed).

Lots of heat: using the UPS to measure, the whole system (monitor off) is 159W idle, 286W prime95 blend, 376W small FFT test. My perl/GMP work at the moment gets it to 326W.

Looks like the Q6600 G0 that this replaced was at 3.2GHz and 50C. The Q6600B3 in my spouse's computer (still chugging along after 6 years) only got to 3.0GHz before hitting 60C.

Justifying the power bills to an environmentalist spouse is the real trick :).

Here's my daughter's machine I put together last night: i5-4670 3.4GHz using stock cooler, completely default settings. 93C (!) on small FFT stress test, and I'd hate to see it in the afternoon when that room is 10+ degrees hotter. 2x4GB RAM (DDR3, 1600MHz, CL9, 1.5V), Asus Z87M-Plus uATX MB, Windows 8.

db597 Jan 2003 7·29 Posts	Haswell @ 4.3GHz Below are benchmarks for a i7 4770K with DDR3-1866 at 4.3GHz. Prime95 stable at 1.25V, using a Corsair H110 watercooler. HWMonitor reports a 141W power draw on the small FFTs torture test. However, realworld running of 4 simultaneous tests on M6xxxxxx is ~115W. On my sample at least, pushing to 4.4GHz requires 1.27V to be p95 stable. At that level, power draw reported is over 150W+! A bit uncomfortable for 24/7 operation, so I'm going to stick to 4.3GHz. --- Compare your results to other computers at http://www.mersenne.org/report_benchmarks Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz CPU speed: 4002.13 MHz, 4 hyperthreaded cores CPU features: Prefetch, SSE, SSE2, SSE4, AVX, FMA L1 cache size: 32 KB L2 cache size: 256 KB, L3 cache size: 8 MB L1 cache line size: 64 bytes L2 cache line size: 64 bytes TLBS: 64 Prime95 64-bit version 27.9, RdtscTiming=1 Best time for 768K FFT length: 2.995 ms., avg: 3.017 ms.

The times for less than 8k seem pretty constant as if only one core is used. 8k actually slows down significantly with 16 threads. 8k is probably just the first multithreaded run(i.e. the first test with >16 cores). I would suggest pming prime95 in case he hasn't already seen this yet.

henryzz Just call me Henry "David" Sep 2007 Cambridge (GMT/BST) 7·29² Posts	The reason you are struggling to keep below 60C these days is because they aren't designed for that. They are designed for much higher these days. 80C might be a good aim these days. My CPU would die from that heat though(Q6600 G0).
