advzip: "Failed tell" error for ZIPs larger than 2GB in size

Ah, good points, I forgot about overflows. The load is small, but I'd have thought that it shouldn't affect clock speeds much? The AVX offset is at default ("Auto"). I'm not sure what value it selects - the motherboard manual doesn't say much either: "If set to Auto, BIOS will configure this setting automatically". I could select a value I suppose, but I've been trying to test at stock settings. I retried with the modified program: #include <immintrin.h> int main(int argc, char** argv) { switch (argv[1][0])...

Largely the same result unfortunately. I decided to set up a test using the program: #include <immintrin.h> int main(int argc, char** argv) { switch (argv[1][0]) { case 'i': { // scalar int int n = 1, m = 2; for (int i = 0; i<100; i++) for (int j = 0; j<1e9; j++) { n += n; m += m; } return n + m; } case 'f': { // scalar float float n = 1, m = 2; for (int i = 0; i<100; i++) for (int j = 0; j<1e9; j++) { n += n; m += m; } return n + m; } case 'x': { // 128b int __m128i n = _mm_set1_epi8(1), m = _mm_set1_epi8(2);...

I notice that in CPU-Z's 'Clocks' window, cores 2 and 4 are marked in red, so I wonder if it's managed to detect something there. I tried WinRAR's benchmark, setting affinity to one core, and leaving it for a while, and repeating for each core. Screenshot of HWiNFO attached. This benchmark doesn't seem to stress the CPU much, as the CPU fan didn't spin up at all, and none of cores seem to really go beyond 4.1GHz. Despite some of the readings showing a higher max clock rate, I suspect they may be...
-
Oops, my mistake, so only 2 cores disabled on 7820X, but unknown as to which ones. The core numbers do all match up: Task Manager, HWiNFO and 7z's affinity mask (I was originally setting affinity using Task Manager). Using -stm3 -mmt2 I can see the first two threads in Task Manager use all the CPU, and HWiNFO shows Core 0's frequency scaling up, and I've repeated this for all cores with the same result. I left HWiNFO running whilst I ran test_affinity, and it does show cores 2 and 4 boosting to 4.5GHz,...
-
That's rather interesting. Do you think it may depend on the positioning of the cores and which slice of L3 the data is stored in? From what I know, the mesh can require 1 or 2 hops to get the data. I believe the Skylake-X LCC die supports 12 cores, so presumably 4 of them are disabled on the 8 core CPU. I don't know whether it's possible to determine the physical positioning of the cores and how much of an effect that'd have. You also don't think that turbo would distort the clock timings a bit?...

Results attached

CPU-Z screenshots attached. Interestingly, the DRAM Frequency seems to jump around, usually at 1700MHz, but sometimes going down to 739MHz - some powersaving feature? (I never knew DRAM would throttle down, though it's usually at the right speed)
-
The RAM is this: http://www.corsair.com/en-us/vengeance-led-32gb-4-x-8gb-ddr4-dram-3466mhz-c16-memory-kit-white-led-cmu32gx4m4c3466c16 XMP profile is applied, but I can't get it working at the rated 3466MHz, so it's running at 3400MHz instead. Everything else is stock; timings are 16-18-18-36, running in quad channel configuration. I'm not at the computer at the moment, so can't post a CPU-Z screenshot, but hopefully that's most of the info.
-
Here you go! I'll be away from the machine for the next few days, so if there's any more tests, it'll take a few days before I can run them.

Oh, I see now, the batch file needs to be run with admin rights (I thought only 7-Zip needed admin rights to install large page support). Updated results (CPU fixed at 3.6GHz, mesh fixed at 2.4GHz) in results-stock.7z And here's a run with the following BIOS options enabled: EIST C-States / C1E Intel Turbo Boost ("Enhanced Turbo" disabled) Clock rate: 1.2GHz idle, 4GHz load across all cores; single core seems to jump between 4.1-4.3GHz, though this is just what I'm seeing in HWInfo when running Prime95...

Not sure if useful to anyone, and couldn't find a more appropriate place to post this, but I ran the benchmark found at 7-cpu.com on the following system: CPU: Intel Core i7 7820X @3.6GHz RAM: 4x8GB DDR4 3400MHz CL16 OS: Windows 10 x64 Turbo/powersaving options disabled in the BIOS, so CPU runs at a flat 3.6GHz across all cores. I tried installing 7-Zip, according to instructions, and even ticked 'Use large memory pages' in the options dialog, but it seems some tests returned 'Not enough memory'....
