Real vs available memory
I have a Dell Studio XPS 7100 that came with 4 gigs of memory. I have added another 4 gigs but there is a problem using it. The system BIOS sees the additional 4 gigs and apparently so does FreeBSD but I get this during boot. real memory = 8589934592 (8192 MB) avail memory = 3400794112 (3243 MB) How do I get use of the full 8 gigs?

You haven't posted a uname -a so I can't be sure, but I'd guess you've installed FreeBSD i386 which is 32-bit and need to reinstall with amd64. -- Brooks pgpwyL8rMrxwF.pgp Description: PGP signature

Run this command: sysctl -a | egrep -i 'hw.machine|hw.model|hw.ncpu’ If you see “amd64” in there, you want the 64 bit (amd64) version of FreeBSD. If you don’t, you’re out of luck.

Patpro, Is there a reason your saying Frank can¹t use 64 bit version of freebsd? That cpu is 64 bit capable. The hw.machine and hw.machine_arch just seem to be reporting i386 because that¹s the installed software version. ‹Nick On 12/9/14, 11:12 AM, pat...@patpro.net pat...@patpro.net wrote: On 9 déc. 2014, at 17:07, Frank Seltzer fran...@bellsouth.net wrote: frank_s@xxx:/home/frank_s % sysctl -a | egrep -i 'hw.machine|hw.model|hw.ncpu' hw.machine: i386 hw.model: AMD Phenom(tm) II X6 1035T Processor hw.ncpu: 6 hw.machine_arch: i386 You cannot use a 64 bit version of FreeBSD, so you must compile your own kernel with PAE: https://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/book.html#memory-i38 6-over-4gb ___ freebsd-hardware@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to freebsd-hardware-unsubscr...@freebsd.org ___ freebsd-hardware@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to freebsd-hardware-unsubscr...@freebsd.org

Re: HyperThreading on Intel Xeon Haswell, a benefit?
Ohartmann: From my experience, mostly compiling FreeBSD sources from scratch ... a dual core, 4-thread CPU at 3.3 GHz takes ~ 60 minutes to build world, the same as a 4-core castrated i3 with disabled SMT. Switching off SMT on the dual core ... Using SMT in some FPU heavy caclulations on Sandy- and Ivy-Bridge CPUs (Haswell is not available as XEON to me at this very moment), I see Adrian: I've done some basic experimenting with SMT on network loads. ...

This evaluation should not be strictly confined to Intel, after all, AMD has CMT which is similar to HTT (not clear whether it's on Opteron, FX or APU lines). Though it will probably be 2016 before AMD really capitalizes and shines on their full architecture vision. By then Intel will just shift a few gears to match. So we should probably stay on subject Intel HTT for now. http://wccftech.com/amds-high-performance-processor-cores-coming-2015-giving-modular-architecture/ http://en.wikipedia.org/wiki/Simultaneous_multithreading http://en.wikipedia.org/wiki/Hyper-threading http://forums.anandtech.com/showthread.php?t=2381524 My thought is that the available evaluations of SMT are all 'old'... discontinued processors, old compilers, old schedulers, etc, all dating back to the Intel P4 arch.
