Sup & THX people for all the INFO!
Hay Schiers,
"I can switch it on and off like I want. The option to allow/disallow it is about
MP (advanced settings) and the version to support."
I have a Intel SL6Z3 Pentium 4c 2.4GHz 800MHz FSB with HT. This new chip come's with the NEW MO core stepping. (Costa Rica) Now Im trying to over clock this Vcore 1.70v CPU to 275MHz FSB (3.3GHz/1.1GHz FSB) 5:4 ratio, Ram 2.70v DDR440 - 220MHz @CL2.0-3-3-7-8 with my PC3500, AND WITH HT (HYPER-THREADING)
Right now my Vcore 1.60v CPU and 225MHz FSB @(2.7GHz/900MHz FSB) 1:1 ratio Ram 2.70v DDR450 - 225MHz @CL2.5-3-3-7-8 and NO HT (Hyper-Threading) On Intel STOCK Air.
I have also tryed Vcore 1.6 CPU and 260MHz FSB @(3.12GHz/1.04GHz FSB) 5:4 ratio, RAM 2.60v DDR416 - 208MHz @CL2.0-3-3-6-8 and NO HT (Hyper-Threading) On Intel STOCK Air.
http://www.msi.com.tw/program/service/forum/index.php?threadid=32697&sid=
PLEASE HELP ME! GET HT (Hyper-Threading) WORKING!
Please show how to do it step by step please
I have BIOS 1.8 (Bugy) Need Bios 1.9 for new microcode update to get HT properly recognized with an option!
OR IS THERE ANOTHER OPTION?

Disable Intel CPU Hyper threading in Oracle RAC environment

Dear Expert,
Does disable CPU hyper threading will have direct impact or maybe unexpected behavior to Oracle RAC database?
Actually the background of this question is we have many received packet queuing on the network layer waiting to be processed. Investigation leads to the processor utilization which shows that many processor are still in idle state or not used when the other processors are busy processing incoming request.
I have visited some oracle note like
CPU Count Consideration for Oracle Parameter Setting When Using Hyper-Threading Technology (Doc ID 289870.1)
Oracle and Hyper-Threading (Doc ID 205089.1)
Using PROCESSOR_GROUP_NAME to bind a database instance to CPUs or NUMA nodes (Doc ID 1585184.1)
These document already give useful information but i wonder if there is any possibilities risk or another consideration of disabling cpu hyper threading.
Please let me know if any other information required.
Thanks.
Best Regards,
Jolly

As far as I know it is set as cpu architecture and mobile chips don't have the option. Not 100% as I've never needed to do it.
Better bet would be to check Intel ark and forums with them I expect.

Intel Xeon Hyper Threading

Hi there,
Any experienxes with $SUBJECT and Solaris 10?
How stable is hyper threading support, and how much does it degrade performance, if I switch it off?
I've read about the security vulnerability with hyper threading, but I don't really care about it. I'm more interested in performance/stability.
Thanks,
Imre Csatlos

CPU_COUNT is a parameter dinamically adusted by the Oracle instance. Oracle perfectly supports hyper threading and there is no need to change the value of this parameter.

Oracle support Intel Hyper Threading??

Does anyone know if the Oracle 9i and 10g database supports Intel's new Hyper Threading technology???

Cody,
Please read Oracle's Note:205089.1 on metalink.

I can't see hyper threading function in my bios

I have a CPU celeron 2,4 ghz, MB 865pe neo2 LS. Problem is I can't see hyper threading function in my bios(ver. 1.5)

kowno,
I know Celerons are not ht cpu's but I want to know if that it's normaly or it's a problem with my MB.
thanks!!

845PE Max2 & Hyper Threading in BIOS?

Hi all.
I know i dont have a Hyper Threading CPU
but i dont have the option in my BIOS,why?
Im using the latest bios v1.2.
Shouldnt it be an option for it,like the manual says?

MSI 845PE max2 (MS-6704) bios 1.2
has HT-function enable/disable in
in Advanced bios features -menu.
It may require DDR333 , bur I'm not sure.
It's different thing, when you enables it without 3,06 GHz cpu, works it or not. Maybe not...

Unable to detect Hyper Threading of CPU SL6WE 3.2 in MSI-865PE Neo2

Hi! I am new to this forum and need some help. I have just installed a Intel Pentium 4 3.2GHz Northwood SL6WE 478 800MHz/512k . I bought this on e-bay and understand that this cpu supports hyper threading. I have enabled hyper threading in the bios, but only see one cpu in Widows System Properties and only one cpu in Windows Task Manager. I had a 2.6 cpu installed previously, no hyper threading. My motherboard is an MSI-865PE Neo2 version 1.1, 2GB Ram ( 4x512 ?), Thermaltke TR2-430W power supply, Freezer 4 Arctic Cooler, Nvidia GeForce 6600, LG DVD RAM burner, 16x DVD ROM, WD 250 gig and an Hitachi 80 gig hard drive. I also used Arctic Silver 5 thermal paste (after using Arcticclean and Surface Purifier). Have I missed somethig? Would appreciate help in solving why I have no hyper threading.

200 7-3-3-2.5 Ultra Turbo and 212 5-3-3-2.5 Ultra Turbo is a
no boot. Thinks ultra-turbo tries to set mem timings to
2-2-2-5 below 218FSB and my memory can't do that.
Turbo boots ok. Normal setting disabled PAT.
200 2.5-3-3-7 Turbo PAT on 4.6GB/s
200 2.5-3-3-7 Normal PAT off 4.2GB/s
212 2.5-3-3-5 Turbo PAT on 4.8GB/s
212 2.5-3-3-5 Normal Pat off 4.5GB/s
Also tried 250 1:1, not prime95 stable
250 2.5-3-3-7 Ultra-turbo 6GB/s
I think pat is disabled above 218FSB on
1:1 and 5:4 setting, but not on 4:5 setting.
You should get close to or above 6GB/s at
1:1 250 3-3-3-5 bios overclocking.
Maybe something is running in the background
stealing cpu power or something?
Well, you have to test some more, maybe a
fresh windows setup will help?

Satellite A500- Is there a way to disable Hyper-Threading technology (HTT)?

Is there a way to disable Hyper-Threading technology (HTT)?
It is really bothering me with some apps,..
I cannot seem to find it in bios,..1.5,.. was it in earlier bios?,.. is there a way to roll back,..
Is it even possible,..
Message was edited by: rekof

I know that, but why would toshiba lock it out in the bios 1.5 ,.. even Intel suggest disableing it,.. Its for future proofing,.. for now it does more harm than good,.. for some users atleast,..
Hope we get this option in next bios,.. I would understand if it would be harmful for a product,.. but it is not,..

Can't get Hyper-Threading to work on MS-6788

Hi,
I have just purchased a MS-6788 motherboard which I am using in conjuction with a P4 2.8Ghz. I installed Windows XP on to the computer and noticed that the OS can't see hyper-threading. I checked the BIOS and in the section 'Advanced BIOS Features' there isnt the option for 'Hyper Threading Function'. Do you know why this is?
Cheers,
Dan

Sorry to be the bringer of bad tidings but ... The only Socket 478 P4 533mhz that does Hyperthreading is the 3.06. All the other Socket 478 P4 HT processors are the 800mhz flavour.
For confirmation by Intel themselves, see http://processorfinder.intel.com/details.aspx?sSpec=SL6PF and note that under "Supported Features" there is nothing. Also check the 800mhz version of the 2.8 at e.g., http://processorfinder.intel.com/details.aspx?sSpec=SL79K and you will see Hyper-Threading Technology under "Supported Features".

Is Hyper-threading enabled on the i5 and i7 iMacs

I am interested in upgrading to a 27" i5 or i7. According to intels site all i-core processors support Hyper-threading. At work I use a quad core Xeon on a HP computer with Windows 7. The system reports that I have 8 cores in performance monitor as it sees each core as 2 cores with Hyper-threading enabled in the Bios.
Does Apple enable hyper-theading in EFI and does Mac OSX see 8 cores in the activity monitor and correctly show the activity of each thread? I suspect if it only shows 4 cores that hyper-threading is not activated on the iMacs. I want to get the most out of the processors capabilities since I am paying a premium for it and so I wont get a current generation machine if it is crippling the processors ability to run 2 threads per core as intel advertises. I would expect with Grand Central in 10.6 that hyper-threading would dramatically increase performance.
Can someone answer this question definitively?

Intels site states clearly that the i3 i5 and i7 all support hyper threading.. if only the i7 supports it on the iMac then apple is crippling the chip..
http://www.intel.com/products/processor/corei5/index.htm
http://www.intel.com/products/processor/corei3/index.htm
So is apple crippling the chip????

Oracle 9i R2 and Hyper threading

Hi
This is a matter of confusion to me, I've tested Oracle 9.2.0.1.0 on several machines with Hyper threading 1 CPU Intel and Dual Xeon servers.
When installing oracle the CPU_COUNT and PARALLEL_THREAD_PER_CPU parameters are set automatically.
ie: Intel 3.0 HT
CPU_COUNT = 2
PARALLEL_THREAD_PER_CPU = 2
Dual Xeon 2.8 HT
CPU_COUNT = 2
PARALLEL_THREAD_PER_CPU = 4
with this default settings our application is dragging it's feet (developped on 4.5 upgraded to 6i client/server)
But if we set
CPU_COUNT = 1
PARALLEL_THREAD_PER_CPU = 2
for the Intel the app goes lightspeed
and
CPU_COUNT = 1
PARALLEL_THREAD_PER_CPU = 1
for the xeon again lightspeed
I didn't face this problem with non HyperThreasding CPUs
My question:
Why is this anomoly, what's the workaround without changing the CPU_COUT parameter?
did anybody else face any problem like this? does this happen in 10g???
Thanks in Advance
Tony S. Garabedian

Any suggestions? Any ideas??

Z77a-gd65 supports hyper-threading?

I have seen in some sites in Internet that the z77a-gd65 supports hyper-threading, but there is no mention of it in the MSI official site nor any BIOS option to enable and disable hyper-threading is described in the manual
Do you guys know whether multi-threading is supported or not?
Thank you very much in advance for your reply!

Thanks Froggy Gremlin for your reply.
There is no shot of this subsection. In page 2-10 there is a shot of the "OC Section" and in page 2-15 a reference to a read only CPU specification sub-menu, but no reference to the HT-setting at all. Maybe I am reading an outdated manual, but it is the one from the official MSI site at //download2.msi.com/files/downloads/mnu_exe/E7751v2.2.zip
But if you have the mainboard and you know there is this option, I trust your word. I am probably buying it but wanted to know before if this option was available.

Oracle Linux 6.2 - hyper-threading

Hello
two simple questions, I hope 8^)
if I installed OL 6.2 and then also upgraded to UEK R2, on X64 Intel server - both tasks done with hyper-threading enabled and then I want to disable hyper-threading after OS installation - do I need to make any OS system/parameter changes at Linux OS level or simply turn off H/T at hardware level and reboot the server ?
is there general recommendation re when H/T is beneficial on Oracle Linux with UEK ?
what about if I added more RAM to the same 64-bit Intel server? Any Linux OS changes required to get all RAM recognised by OS ?
thanks!

A recommendation does not mean the absolute best solution for every situation. There has been no information about any particular software deployment or even the particular CPU in question.
I agree with you that enabling or disabling HTT in regard to achieving the best possible performance for a particular scenario is subject to testing. But, if someone asks me what is the recommendation about HTT in regard to Oracle UEK kernel, and possibly Oracle RDBMS, my suggestion is to use the default and leave HTT enabled. I'm not aware of any documentation that suggest to generally disable HTT when using Oracle. Saying "it depends" is scientifically correct, but not helpful.
There are already plenty of discussions about HTT on the net. You can turn HTT off and experience a performance increase, but there is also a chance the performance was even better with HTT enabled in a properly configured system or application. There are cases were HTT apparently slows down performance, but drawing a conclusion about enabling or disabling HTT in regard to performance is often too simple due to many other factors that can interfere with the results.
Dude the link you supplied referenced some old ibm information.Well, Hyper-Threading isn't a new feature.
For what it's worth, check out http://en.wikipedia.org/wiki/Hyper-threading in particular "Drawback history".
Or http://www.intel.com/support/processors/pentium4/sb/cs-017371.htm#1c which also links to more performance info.

MS-6535 Hyper threading

I have the Heremes 651 with MS-6535 Ver 2 Mobo. I dont see an option in bios for supporting hyper threading.Does anyone know if this board supports hyper threading or if there is a bios update that will help
thanks

OK, now you need to tell the B stepping from the A stepping.
It would need to be a really new board in order to support it, in fact I am not sure B stepping 648 chipsets are available yet.
MSI bios note 3.11.02 for 648 Max:
Quote
-Remove Hyper-Threading in BIOS Setup (chipset does not support it)
I assume that there will need to be a new revision of the board in order for B stepping chipsets to be used.

P6N-SLI-FI -hyper threading on when i have Pentium D installed

i don't know what happen just shut down my computer for the night, started it back up when i woke up the next day, and it took abit to boot i want to tab to see what it was, and hyper threading was on but my cpu does not support hyperthreading.And my Dvd drive is not being detected as well. I cleared cmos and it still was there, the computer runs fine but i want my dvd drive back the most.

I had a disappearing DVD problem in Vista on an Abit board. It would only show up after a reboot (or 2). From a power off state, Vista would simply not recognize the drive, even though BIOS did and POST listed it first of all drives. I don't have it in front of me, but the solution was to go into the registry and delete upper and lower limits for the drive. I wish I could be of more help, but hopefully I've remembered enough for you to Google the rest.
