Okay, I just found something interesting... Wrote a little program to pass some time the other night, revisiting my knowledge of CPUID instructions w/ some help of the intel p4 technical documentation... Anyway, long story short, I got confliting results for the presence of HTT, when I did a feature flags list it showed HTT as 1 (Yes) but, when I looked into it more closely, found it HTT is disabled. Now, I thought maybe something was ****ed up with my code (as i'm only running a 2.53 not a 3.06), so i downloaded PC Wizard eXPerience Edition from cpuid.com and did some checking with it. It shows Number of physical processors: 1 and Number of Logical Processors: 1 ... but again HTT disabled. Thoguht well maybe it'd show logical proc's: 2 if it did have HTT so I ran in benchmark mode, "Processor Benchmark", and it shows me the graphs of add/mul, division, sqroot, whestone ... anyway in the "Information" table i look and see:
General Information:
Processor: Intel Pentium 4 - Northwood
Frequency: 2533.16 MHz
L2 Cache: 512 Kb
Front Side Bus Speed: 133 MHz
Bus Speed: 533 MHz (QDR)
Processor Technology:
MMX: Yes
SSE: Yes
SSE2: Yes
Hyper-Threading: Yes
So I just thought well, i've looked over my code for detecting the HTT feature flag set and making sure that I wasn't confusing the **** with some other feature flags (been known to happen once or twice before :)) so ran PC Wizard just to see, and gave me the same type of results so I'm doubting that both programs are in err...
To make a long post a little longer, heh, what I'm just asking basically is, if someone who's running a 3.06ghz p4 would download pc wizard, and see if their info matches up (HTT wise) with mine (of course yours'll say enabled not disabled but still, if the # of physical procs and logical procs are the same... and if the benchmark info is the same) lemme know :) Will find a way to enable HTT on this proc if it's there for sure
