Hyper-threading

Hyper-threading

[Richard B. Johnson]

Hello,

Anybody know how to enable hyperthreading? I
have an ABIT IC7-G motherboard (absolute garbage)
with a Phoenix AwardBIOS. They don't provide
any BIOS upgrades and say you have to contact
the board vendor. ABIT doesn't answer email
and www.abit.com ends up being answered by
www.motherboards.com that doesn't provide
any support.

The crap board came with the peripherals
I paid for, stripped out (no network, etc).
Don't make the mistake of buying this garbage
as I did. I thought that since it was more
expensive than others, it __must__ be the
best!!!

Cheers,
Dick Johnson

Okay. Thanks to you all for the site info. The two US sites
refused connections, but Tiwan worked.

I downloaded the latest, compiled May, 19, 2003. BIOS
release 1.3.

This converted the motherboard into a DOS-only machine.
It would not boot Linux much beyond the LILO prompt  but
it would boot DOS off from a floppy fine.

There was nothing in the BIOS setup to enable or disable
hyper-threading. There was some junk about enabling
'ultra', 'turbo' and 'fast'. If 'turbo' was enabled,
I was able to boot Linux-2.4.20. This is the dmesg
output. It will not boot in any other 'position'.

I wouldn't worry about hyperthreading too much anyways, seeing as how this
cpu doesn't support it anyways.

Well it is supposed to. It's a pentium 4 Xeon. If it doesn't
support it, ether the CPU or the motherboard are broken.
I'll bet on the motherboard.
Look further up the dmesg output and you'll see XEON(tm) and
2 CPUs total.

Indeed, I saw that.  On the P4 2.66ghz that you have, the "second" cpu is
disabled by intel, as they sell hyperthreading only on the newer Xeon P4
(which you don't have), and the new 800FSB (4x200) units, which again
you don't have.

..... CPU clock speed is 2672.7802 MHz.
..... host bus clock speed is 133.6388 MHz.

There is a Xeon 2.66 part, however it has 603 pins, and would not fit on
your IC7-G board, which is a P4 board, not a P4 Xeon board,

CPU0: Intel(R) Pentium(R) 4 CPU 2.66GHz stepping 07 is correct.

OT:  Are your two 100mbit cards PCI or something?  I noticed the onboard
gigabit adapter isn't detected.

Some Pentium 4 chips support HT even when they officially "don't". For 
example, my system has an Intel MB and a Pentium 4 2.8GHz processor; it 
boots using HT just fine. From a recent boot:

Tycho kernel: CPU1: Intel Pentium 4 (Northwood) stepping 07
Tycho kernel: Total of 2 processors activated (11042.81 BogoMIPS).
Tycho kernel: cpu_sibling_map[0] = 1
Tycho kernel: cpu_sibling_map[1] = 0
Tycho kernel: ENABLING IO-APIC IRQs
Tycho kernel: Setting 2 in the phys_id_present_map
Tycho kernel: ...changing IO-APIC physical APIC ID to 2 ... ok.
Tycho kernel: ..TIMER: vector=0x31 pin1=2 pin2=0
Tycho kernel: testing the IO APIC.......................
Tycho kernel: .................................... done.
Tycho kernel: Using local APIC timer interrupts.
Tycho kernel: calibrating APIC timer ...
Tycho kernel: ..... CPU clock speed is 2783.0819 MHz.
Tycho kernel: ..... host bus clock speed is 132.0562 MHz.
Tycho kernel: checking TSC synchronization across 2 CPUs: passed.
Tycho kernel: Starting migration thread for cpu 0
Tycho kernel: Bringing up 1
Tycho kernel: CPU 1 IS NOW UP!
Tycho kernel: Starting migration thread for cpu 1
Tycho kernel: CPUS done 2

Note the "132.0562" MHz bus speed.

I obtained my system directly from Intel; however, I know of a few 
people who obtained Pentium 4 chips from retailers, and their processors 
support HT with a 4x133 bus.

Well, the CPU I bought was supposed to support hyper-threading. That's
what it even says on the box (new Hyper-thread technology)! I guess
Hyper-thread technology isn't "hyper-thread", only its "technology",
like it's got some pins and takes power.

These were purchased together to be a "hyper-thread" board
for my new system. I have always had two CPUs since SMP became
available, and I wanted to experiment with the new "single-CPU"
SMP architecture.

I got ripped off. I got sold a board that doesn't have the gigibit
adapter populated plus, you can't tell from a distance because the
connector is present, but has some metal tape covering the hole.

This board costs $275 plus the CPU was $635. I got badly raped
and the vendor won't take them back.

RE: Hyper-threading

[Robert White]

Note to US consumers (or people purchasing things through any US institution
or facility) WRT this sort of thing.

If, in deed, your ordered this thing under a set of specifications that it
isn't meeting (e.g. the gigabit isn't there but it is on the listing from
the advertisement etc. the seller is all sorts of liable.  (I am presuming
wrong doing, if you just didn't shop around but you did get what you
ordered, this doesn't apply to you 8-)

Particularly if you used a credit card.

The things to do (and these really do work.)

1) (no matter what kind of payment was used) go to http://www.ftc.gov and
file a complaint.  This is something between advertising and wire fraud and
there are armies of petty bureaucrats at the FTC who live to vent spleen on
that sort of thing.  Example: Bank of America "held" a _certified_ check my
roommate deposited into his account, even after the funds cleared the
issuing account.  He had proof.  There is a %1000 fine for that (yes, three
zeros!) and BofA paid just over 60,000.00(USD) in fines for "being slick"
with his account.  The more proof you have (print out of the advertisement
or web page etc) the more likely you are to get satisfaction; mention what
proof you have etc in the complaint.

2) If you used a credit card (again on a US bank or institution) complain to
your bank and/or the lead company (e.g. Visa Corp for a purchase made with
any thing imprinted with a "Visa" logo).  The person or entity who listed
the charge against your account has an agreement with the issuing bank or
the main company that, among other things, makes them liable to provide the
goods or services paid for, or to make good on the mistake, or to abrogate
the sale.  They have also agreed not to be fraudulent about their actions
since Visa Corp (et al) cant make you pay for charges that are
inappropriate.  Even "all sales are final" notices accompanying a sale do
not supercede this agreement if what was delivered didn't match what was
purchased.  A business can lose it's entire ability to process a card (e.g.
Visa will pull their contract, and that can end a business) for something as
small as one failure to perform.

It's amazing how quickly a business will bend over and get all helpful if
they get caught out and you actually make the call.

It all boils down to proof.  Did you print that "receipt" page?  Do you have
the invoice?  Did you (can you) print the Advertisement?  Does it say it
will on the box?   All these things are useful as proof.

At the very least, if they didn't deliver, you may not have to pay.

And remember, a merchant can disclaim fitness for a particular purpose ("you
balancing your checkbook" for example) but they can not "disclaim" anything
in the sales agreement, and claims on the page and on the box are therefore
binding no matter what they say.

Call the merchant one more time.  Get the name of the guy you are talking
to.  Say "This product doesn't do what the box says it will.  Replace this
with something that does, or give me my money back, or my next calls will be
fraud complaints to my bank, Visa corp., and the F.T.C."  Ask for his
supervisor, get his name, repeat your statement.  If/when they say no, thank
them for their time politely.  Then assert your right not to be screwed...

Rob.

Google for Abit.  It isn't always a case of foobar.com leading to the

You prob want to try:

With the bios at:

I do not see anything HT specific, except a logo thing (maybe).

Well, its a matter of opinion I guess, but I have always had
good results with Asus motherboards.  All Asus bords with chipset
supporting HT have BIOS updates to enable support.  Also, if you
look at older A7N8X (Nforce2 chipset) boards, they now have support
for 400Mhz CPU even if not the Ultra400 Chipset (BIOS update) ... makes
a difference if you do not have money to upgrade =)
