Intel Virtualization Technology (VT) isn't related to the problem we are experiencing with Dual-Core unfortunately.

Quoted from Hardware Secrets

Formerly known as Vanderpool, this technology enables a CPU to act as if it were several CPUs working in parallel, in order to enable several operating systems to run at the same time in the same machine.


So it's only benefitial if you are running VMWare and I assume, Parallels.

Had to reply, my speedstep package has NO problems with mounting dmg's. My package is for 10.4.8 only, and if you try to use it on 10.4.9, you'd better grab the 10.4.8 kernel.framework and system.kext.
If used on 10.4.8, I repeat, it DOES NOT have any issues with disk image mounting.

Now as for the sleep possibly fixing both cores, I can say that waking from sleep fixed a problem on my h.p.
If I didn't send it to sleep then wake it the fan would never come on and it would eventually thermal and shut off.
I eventually found that removing AppleACPIThermal.kext fixed this problem for me without sending it to sleep.

Moral of the story, sending a laptop to sleep and waking initializes the bios/cpu/memory/devices differently then a normal power up. Weird, but true.

Paulicat.

Cheerz for the post Mr. Paulicat :)

I hadn't tried your speedstep package personally so I'm glad you cleared that up for us.

Do you know what in the system.kext differs from the 10.4.8 to 10.4.9, helping resolve this issue?

I'm anxious to install this speedstep package as it seems to be the answer to some other issues I have been having. I am assuming this will help out many of us (not just Dell users as you seem to have an H.P) as I was thinking for a little while this thread was started for just Dell users - Earlier someone mentioned to me "read the thread, this is for Dell users." Although I stumbled here because of the thread title, not the thread.. If this is only for Dell users, can someone please fix the title!?!

Thanks,
TheVoiceOver

Well, it's essentially for Dell users and anyone else who experiences stuttering with both cores enabled on a CD or C2D proccy.

Finally managed to get sleep (and therefore both cores) working on an Inspiron 9400 with an NVidia GeForce Go 9700 GS.

After much tinkering and many reinstalls, I was able to isolate the video card as the weakest link. Sleep WILL NOT work with Titan or Natit, even if I'm using the 10.4.8 GeForce kexts; using NVidiaEFI 1.0.2 with the 10.4.8 kexts works beautifully, however. Here is the final journey I took to get it working, as far as I can recall:

1) Installed JaS SSE2/SSE3DVDwithSemthem10.4.8kernel.
2) Installed mobility.kext(found on this forum) andpatchedAppleHDA.kext
3) Installed JaS 10.4.9 upgrade combo package
4) Turned SafeSleep off with 'sudo pmset -a hibernatemode 0'
5) Turned off 'Enable disk to sleep when possible' (or whatever) and changed Display Sleep to 'Never' in Energy Settings
6) Installed NVidiaEFI 1.0.2 kext and removed Titan.kext
7) Fixed relevant permissions
8) Reboot and used kernel flags 'cpus=2 fsb=166 fn=1' (if I do not specify 'fn=x' then I get thrown into single user mode during boot)
9) Use Apple menu to enter sleep mode after OS X is up and running, and the machine goes into S3 state without any issues. Upon wake, both cores are functioning.

'uname -a' confirms I am using the 10.4.9 netkas HPET kernel and I did double-check to make certain that the GeForce/NV40 kexts were still the same version as the 10.4.8 DVD. I also replaced IOPCIFamily.kext and IOPCCardFamily.kext with ones I found in a random thread at one point (attached as 'Extensions.zip', but not the same 'Extensions.zip' available in the 'Useful Files' thread), but as I later re-replaced them with theoriginal versions off the JaS DVD, I do not believe they played an integral role in getting sleep to work.

As for BIOS settings, I'm using the latest A08 and I have NX enabled, Virtualization/Vanderpool enabled, SpeedStep enabled, and both cores enabled (obviously).

Hopefully this will help some of you who are having issues with entering sleep mode and using similar video devices. If not, let me know and I will have a trawl through my Extensions folder to see if there's anything else I messed about with and forgot (it was about the 8th reinstall, so details tend to get a bit mixed up when you're not actually expecting things to work on that particular attempt!)

Best of luck to all! (Now who's going to solve the subwoofer issue so I can have a fully working machine... ? ;) )

Can you enable/disable cores at will?

8.9.1 enabled that on my Fuji.

Thanks for that post, tbcarey. If somebody is able to reproduce this, I'd say it requires an own thread or tutorial.

I am only curious if there are any similar possibilities with GMA950 graphics that many Dell-owners are using. The video-card seems indeed to be the critical factor when trying to get sleep, and maybe dual core working on the Dells.

Did you already have any time to benchmark your system? What kind of improvement do you get with dual core?

Again thanks for your efforts!

Did sleep worked on any of the previous version of OSX86(10.4.5, 10.4.6,.10.4.7 or 10.4.8) with Dell E1705/9400 with GMA950?

"Going to sleep" worked very well here with 10.4.6 and 10.4.8, but the display never wakes up. Same in 10.4.9 now...

Display doesn't wake on an Intel GMA950 based video. I think it is fairly clear that Intel Integrated Video has a hard time waking from sleep. Anybody know of a solution?

I've just run Xbench 1.3 in dual core mode and then rebooted to single core mode by using the cpus=1 kernel flag. Here are the results:

Single Core
Overall - 113.64
CPU Test - 101.57
Thread Test - 122.76
User Interface Test - 290.28

Dual Core
Overall -130.36
CPU Test - 103.26
Thread Test - 198.38
User Interface Test -400.58

I've included the User Interface Test results because the variation in scores was so great; all of the other non-CPU-related tests produced nearly identical results. I haven't checked to see what other (non-Dell) Core 2 Duo usersarescoringforCPU and Thread Tests, but do those results look fairly accurate? Should therebeagreaterdifferentialbetweenthescoreswhenrunningindualcore mode?

On a side note, I've also noticed that the disk test results are fairly abysmal. I consistently score around 36.5 in that test because the Uncached Random Write 4K Block test produces a score of 7.83. Has anyone else using the Hitatchi HTS721010G9SA00 (7200 rpm 100gb drive) experienced the same issue?

Lastly, I just wanted to point out that I am only able to wake from sleep mode ifIspecify the -v kernel flag during boot (or add it to .com.apple.Boot.plist)! I'm not exactly certain why this is or what processes would change as a result, as I had assumed the only difference in verbose mode was the display of text rather than the Apple logo. However, I have rebooted MANY times and recreated the exact same scenario using the exact same kernel flags, and every time I try without -v, it won't wake from sleep. Very odd.

Thanks for posting the results, I think they look fairly accurate and Dual Core seems to be working properly. Especially the big difference in the multithreading test shows that everything is working fine.
I get an overall score of around 96 and an UI score of 290 on a E1505/I6400 with T2250 (cpus=1).

This sounds very odd ineed. Maybe the verbose mode delays the execution of some functions? Not an explanation, just an uneducated guess...

hi, tbcarey,

I tried so search for the mobility.kext in this forum but failed, can you please put it here, thanks a lot.

btw, is it the same mobility as is meant in ATI mobility?

if I am using a 7900GS, do I still need to install that besides the nvidiaefi?

HI,
i notice that both core after sleep is working with kalywayLeopard beta(9a527) release, with titan kext installed. Maybe solution will comes with Leopard...
EDIT: I re-install it, and now it doesn't work. Strange... I have to remember what kext i have installed. Anyway, i will test it when i will have time.
