Hi guys. I have 2 pcs at home. One is a shuttle ss58g2se and the other has an Intel® Desktop Board D102GGC2. On both the Intel and Shuttle websites, the manufacturs say that these boards support Hyper Threading (HT). Shuttle Europe - SS58G2SE Intel® Desktop Board D102GGC2 Overview. To test HT technology I downloaded the HT test utility form Intel's website Hyper-Threading Technology Test Utility The results of this test indicate that HT is not supported by either of my pcs. I have checked my bios and HT is enabled on both of them so can someone tell me what is wrong? Is it that I don't have the correct chipset? If this is the case, why do both websites claim their boards support HT? Please help
I'd say it's a problem within that software and it might just not recognise your mobos having HT tech. See, if the BIOS + the manufacturer says there is HT support, then it simply has to be there. Do you have HT CPU's on the mainboards already or you just wanted to know wether or not you can buy ones?
I have HT on my system and when I tested that utility it always said that the bios does not support it (the bottom test) but HT still works to check if HT is working press CTRL+ALT+DEL and click Performance. If you see two cpu's (see pic below) then your HT is working. also if you have cpu-id /.cpu-z it will show two cpus to choose from and go into your device manager click on CPUs, there should be two 3GHz (or wot ever speed it is).
Thanks newpaws and edijs for your replies. I already have HT CPU's on the mainboard. I will try your suggestions newpaws and get back to you. When I performed the utility test on the Shuttle PC, the processor, chipset and bios test all failed. When I performed the test on the Intel mainboard, the processor test passed but the bios and chipset test failed. I used Intel's processor id utility Intel(R) Processor Identification Utility - Top Technical Issuesto check both my CPUs and this utility states that both my CPUs support HT so I'm not sure exactly what is required to pass Intel's HT test. Thank for your help.
Hi newpaws. I did what you suggested and everything you said was correct apart from cpu-z doesn't show 2 cpus (see attached image). Why does windows show 2 cpus but cpu-z doesn't? I am more confused than ever about whether I have HT or not. Please help.....
hi sorry it doesnt show 2 cpus with cpu-z, but if everything else checked out with device manager having 2 cpus and CTRL+ALT+DEL-PERFORMANCE has 2 logs on the cpu and they both seem to be 'living' then your hyperthreading is working fine if youre still concerned try disabling ht in bios, you should feel a slight performance drop after the welcome screen, without hyperthreading it will start up slower
I've got the same thing with my Intel P4 3.06GHz w/ HT - CPU-z wouldn't show that I have another logical CPU. But everything else shows that HT is up and running - Everest, Windows device manager, DxDiag, BIOS. So, I'd say it's some kinda incompatibility with Prescott CPUs; like, for example, the majority of PC-diagnostic programs that I have used, don't recognise my mobo (but they easily recognise it's chipset), but one does. :dry: By the way... in the lower right corner of the CPU-Z you can see that there is [1] processor and [2] threads, so everything's okay (i've ran the utility on a P3 and it showed, of course, that there's [1] CPU and [1] threads).
just a quick question for edijs you said you have a HT processor what bus speed is it, you said its 500mhz in your "my computer" is it underclocked? i thought all HTs were 800mhz
@newpaws - it appears to be only 533MHz. The Intel CPU ID and CPU-z were showing that. And, no, it's not underclocked (at least not by myself). Actually, I've also heard that P4s like that come with 800 only. Maybe it has been underclocked. Odd. And actually a question emerges - I've had some problems with system stability. Could the fact that my CPUs FSB is 533MHz, but my mobo's (ASUS P5VDC-MX) designed for 800MHz be the cause of that (if my RAM speed's 400MHz ???) :dry:
well to my knowledge all P4 HT processors are 800fps i suspect you've got a faulty or underclocked cpu, sayin that your ram is PC400 which is quite old i believe as ram now go upto PC3200 and PC4000 that may be the reason why
Took a look around: turns out, actually, my P4 HT CPU's one of the kind that HAS 533MHz FSB. It's not underclocked or otherwise modified - it's stock. Sucks though 'cause I have to set my memory speed to 333MHz and the system runs slower. A lot.
I think u've got a P D, which is dual core. Thats y its showing two CPU's. Isnt it? @ ryan, to get the good knowledge about Hyperthreading, you can check with [link=http://en.wikipedia.org/wiki/Hyperthreading]Wikipedia Hyperthreading[/link] or look at [link=http://www.intel.com]Intel's Website[/link].
with hyperthreading it shows up as two logs because Xp is designed to work with both "core's" (even tho its a virtual one) and treats them as individual cpu's in order to fully take advantage, likewise with dual core like yousaid. even more interesting the dual core with HT (currently only selling as the extreme edition) shows up as no less than three logs (possibly four if hyperthreading is established on both die's)
hyperthreading is only used with Intel cpus, its idea is a total new revolution to intel and has a huge impact in performance differences to cores without it. its basically two cpus rolled into one, but with a single core. instead of data going parrallel through the CPU HT allows both parralel and dual strings of data to be processed at the same time, greatly improving performance. they say it improves a P4 upto 33% more performance, but in my experience its a lot more and certinally will not go back to single core (or without HT) but know the dual core offers 80% increase from single cores, thus giving 2.5GHz more performance from a single 3.2GHz chip (offering equilivent to 5.7Ghz of speed from a single cpu) A P4 3.0GHz with HT is equilivent to a 3.6GHz without HT. checkout tomshardware videos here which shows live illistrations, actually the P4 3GHz HT takes first place from the 3.6GHz
