Do we need to update (recommended? non-recommended?) from v26 for core2 duo/quad processors? (nehalem/westmere no sb, no avx, no fma3/4 :razz:) 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 ?? :shock: (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... |
[QUOTE=Prime95;289659]P.S. Can a Phenom user check to see if CPU speed detection is any better?[/QUOTE]Here's what I get:

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. |

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) |

What is your mainboard type / BIOS version? [QUOTE=James Heinrich;289720]And both still don't recognize the architecture:[/QUOTE] 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. |
