Prime95 version 27.3 - Page 2

Do we need to update (recommended? non-recommended?) from v26 for core2 duo/quad processors? (nehalem/westmere no sb, no avx, no fma3/4

) Or we better stay on 26 for these processors? (I am not a big fan of new stuff against stable stuff!)

edit: I will give a test to the new version tonight, when I reach "the" SB-E computer

edit2: (rhetoric) what the hack do you have in 38 MB of sources ??

(firewall kicked me off at about 30, three times, till I realized why, then I clicked "stop" then "resume" in the middle, cheated it, hehe).
edit3: no need to answer, I saw gwnum libraries already, maybe they could be separated, most guys only want to "look" into the sources... not to use them for whatever...

Here's what I get:

v26.6 Build 3:

CPU speed: 9455.57 MHz, 6 cores
CPU features: Prefetch, 3DNow!, MMX, SSE, SSE2

My i7-2600K@4,5GHz with DDR3-2133 memory runs slightly faster compared to 27.2. Three cores, 2560K FFTs.
And as a bonus, Prime95 now correctly detects AVX in my laptop with i3-2310M, wasn't detected in 27.1 and 27.2.

7zip compresses the unpacked source272.zip archive to 4421674 byte (-mx9, 6855628 byte with the default settings).

that was my wondering! the 38MB was the COMPRESSED file.

Anyhow, not that is the reason I posted. I just did a comparative benchmark. Attached the 2.73 vs 2.72 so if George can do anything with it, be my guest. If I could insist on something especially, just say so.

The benchmark is done on an i7 2600k running at 4.35ghz, on a maximus extreme z mobo (quad channel ddr3)

not to mention the few MB of Windows object files, the .c and .asm sources...

That's why I would like to see .7z files as a download option:

Reread the original post. Pay attention to the bold text.

What about when all 6 cores are running?

Both v26.6 and v27.3 detected my 4500MHz Sandy-E as 4428MHz.

And both still don't recognize the architecture:

[Main thread Feb 17 10:01] Optimizing for CPU architecture: Unknown Intel, L2 cache size: 256 KB, L3 cache size: 12 MB

Is this a speed-testing alpha, or should it be considered a semi-stable beta and suitable for production work?

What is your mainboard type / BIOS version?

If you post your CPUID (you can look it up with CPU-Z or a similar tool) George might be able to use the information to improve the CPU detection.

LaurV Romulan Interpreter Jun 2011 Thailand 7²·197 Posts	Do we need to update (recommended? non-recommended?) from v26 for core2 duo/quad processors? (nehalem/westmere no sb, no avx, no fma3/4 ) Or we better stay on 26 for these processors? (I am not a big fan of new stuff against stable stuff!) edit: I will give a test to the new version tonight, when I reach "the" SB-E computer Last fiddled with by LaurV on 2012-02-17 at 07:32

(firewall kicked me off at about 30, three times, till I realized why, then I clicked "stop" then "resume" in the middle, cheated it, hehe). edit3: no need to answer, I saw gwnum libraries already, maybe they could be separated, most guys only want to "look" into the sources... not to use them for whatever...

BigBrother Feb 2005 The Netherlands 2×109 Posts	My i7-2600K@4,5GHz with DDR3-2133 memory runs slightly faster compared to 27.2. Three cores, 2560K FFTs. And as a bonus, Prime95 now correctly detects AVX in my laptop with i3-2310M, wasn't detected in 27.1 and 27.2. Last fiddled with by BigBrother on 2012-02-17 at 11:31
