Confusion about SSE3 support on Intel Celeron D 336

Hi Guys,

 

I'm a little bit confused about the SSE3 support of my CPU ( Intel Celeron D 336 socket 775 ).

All of the technical information I found says that is has SSE3 support. So I created a kernel with

native SSE3 support ( use Maxxuss patches ), but the kernel doesn't work, it works only with the SSE3 emulator patch - strange.

 

I found some code inside the maxxus scripts which will help to show the features of the CPU :

 

sysctl -n machdep.cpu.features

 

but no SSE3 support was shown. :)

 

Am I'm totally wrong here or does my CPU not have SSE3 support ?

 

Thanx for your help.

Yes I beleive all Celeron D 's have sse3 support. I am using a lesser Celeron D 321~5? 2.26GHZ 478 socket.

It says sse3 & PAE in my apple system profiler. Just no NX/ XD.

 

All socket 478 Celeron D processors will not support XD. Only some LGA 775 Celeron D's will support XD. Your 336 Celeron D 775 socket will support both sse3, 64 bit, and XD.

 

I am not sure what is up? What version are you trying to install again? I have had success w/ sse3 in 10.4.1, 10.4.3 (8f1109 & 8f111a).

 

Check your bios setting to see if there is some option for sse3, PAE, and or XD to switch on and off. This is all I can think of.

 

Cheers,

 

PS If you ever want to check which functions you CPU supports I find newegg.com lists the most data without giving you a headache.

Okay, if I'm booting from a Linux CD and use the command you give me it shows SSE3 support, so i gues it has somethink to do with the maxxuss patch.

 

But i still have no success with a Kernel that have only these patches :

 

patch-base.ppf

patch-cpuid_panic.ppf

patch-rtc_panic.ppf

 

If I'm right, I don't need any of the other patches because my CPU supports NX and SSE3.

 

 

Thanks for your help guys.

 

System :

 

10.4.4 (8G1165)

ASRock 775iGV865

Intel Celeron D 336 2.8 GHz SSE3 & NX

ATI Radeon 9800PRO APG 256 MB (only 128MB shown in Systemprofiler QE+CI support)

80 GB SATA Hitatchi HDD

 

Known Problems :

iMovie 6.0.1 crashes if i use Themes, iPhoto Slideshow destroy cursor after Fullscreen(ATI driver problem I gues), WoW crashes after login, Firefox crashes right after start.

 

Testet Software :

 

iWeb works, iDVD works, iWork works, iTunes works, iChat works, Safari works.

I can only answer this from a Linux point of view but if you booted a Linux Live CD and type:

 

grep -i sse3 /proc/cpuinfo

 

That will show a line of text if your CPU is reflecting that it supports SSE3... otherwise it will do nothing.

 

that should be "pni", not "sse3".

Okay this is really driven me crazy, now that i find out my CPU has SSE3 why only it boots

a kernel when i'm apply the SSE2 patch from maxxus. Is there somethink more to do ?

 

Does anybody else has these problem ?

 

Check your messages for a possible solution.

I solved the same problem with my:

 

ASUS P5GDC-V Deluxe motherboard and

Celeron D 336 2.8Ghz with NX and SSE3.

 

Maybe the solution is applying NX/ND patch. It is work for me!!. ASRock Mobos are made by ASUS too.

 

My system is working very well now with SSE3 support

 

Remember!!! --- Base patch AND NoNX patch

 

sorry my english

 

Bye

I'm try out any patch solution, but only when i use the sse patch it works,

if belive that my installation DVD do somethink different at the install.

 

It looks like there is something more behind everything.

 

The next i will do, is to build my own install DVD from scratch with the maxxuss patches.

 

Thanx again for your help.

Let's start from the beginning.

 

Which version of OSX86 do you have? 10.4.1, 10.4.3 8f1099, 10.4.3 8f1111, 10.4.4 or 10.4.5?

 

What happens when you boot from the DVD? Do you see the Apple logo and the spinning circle? Or does your computer restart?

My DVD boots fine, thats not the problem, because it has all patches.

 

The problem is to have a mach_kernel which has no SSE3 Emulation.

 

If i don't use the sse3 maxxus patch my pc will not boot, but my CPU have 100% SEE3 and NX support, i tryed out every patch solution and it run's only if i add the SSE emu patch.

 

I Thing that has something to do with my Install DVD. I belive there is more then just the kernel that have to change.

 

System is 10.4.4 8G1165

Strange... very strange...

 

I am running OSX without the SSE3 emulator on a Celeron D 340 which is the same as the P4 that locossaurorex has but without HT, XD and EM64T (and for S478 not LGA775)

 

Locossaurorex's P4 is more similar to those in the Developer Kits than my proc is.

same issue here on my a64, only work with SSE3 emulation kernel.

 

does the X2 need the cpuid patch to work ? if it doesn't and prolly it doesn't only add base + amd enabler to the orig kernel. If you add the cpuid patch then you need to add the sse3 emulator too without it hangs during the very early booting stage because that patch hides the sse3 capability and there's a check left

Here all the Kernels i patched and tryd in case anyone else wants to av a go. strange how i can only boot with the SSE2 patch now seems like i need the CPUID , but why the SSE2.

 

 

i've explained you why you need the sse2 if you add the cpuid patch but i'll repaste:

 

If you add the cpuid patch then you need to add the sse3 emulator too without it hangs during the very early booting stage because that patch hides the sse3 capability and there's an explict sse3 check left

k, i got that now, why does the cpuid patch hide SSE3 is this really necessary. is there anyway to get SSE3, the way i look at it is if the kernel dont show SSE3 at boot or the System Profiler dont show or see it, then what makes people so sure an app will still use the SSE3 code paths, sureley if nothing else thinks the CPU has SSE3 then the App wont either.

well this is too technical for me, only maxxuss knows why being the coder. Maybe it's just a bug in his patch
