My 845g supports Hyper Threading ??

[dwarfy]

primary, sorry for my lack of English, I'm french

So, there is the "problem" :

-Intel claims HT will be supported on 845g on rev B of the chipset.

-Asus said to a french web site the P4b533-VT they send to them for a review support HT because the i845g on it is a rev A1 of the chipset (all the 845g boards tested by this site before are A0 stepping).

So tonight I take my screwdriver and look my chipset on my p4b533-v (board rev1.01): I've got an A1 chip \o/

hum hum, I fired up my computer, lauch WCPUID and *ouch* :
Look at this pic ! (WCPUID)

Look at this pic ! (CPU-Z)

So, which I could believe ?
Asus, and the "A1 chipset supports HT"
Intel, and the "only B stepping"
or WCPUID ? (a bug in the prog ? Anybody here with a 845g A0 step to see what wcpuid says ?)

WCPUID shows that my Asus P4S533 supports Hyper-Threading Technology. Hmmmmm......

 

[dwarfy]

CPU-Z (really better than wcpuid I think) report the same thing : HT ready.

I had the pic in the first post

Same here.

where your Wincpu picture says HHT. Mine says Jackson technology. Whats up with that?

Hmmn... On my BG7 CPU-Z says also that the chipset is A1 stepping and HT is supported?

Thtat's what Asus say to the french web site, for Asus, his p4b533-vt SUPPORTS HT because of its A1 stepping.

Now this got interesting. Tried with wpuid with exactly same results as you. I read at one page that only the initial stepping of 845G wouldn't support HT and they also stated A1 is the initial stepping, which it isn't as there's A0 as well.

hum, it's totally different than all the other web sites say :/

(and the initial 845g rev IS a0, a1 was released after the a0 stepping (after all, it's logic ))

What does it mean if it says yes to hyper-threading? Mine did!

 

[Nemesis1234]

Add the 845E to the club, CPU Z says that my ABit BD7II-RAID supports H.T.
The chipset stepping is E0 .

The problem is that the plain "supports HT" statement with WCPUID or CPU-Z isn't adequate. It's really up to motherboard manufacturer will they release a BIOS update with HyperThreading support.

My EPoX 4G4A+ uses Stepping A1 and both programs report that HT is supported. However, I sent an email to EPoX regarding the HT matter and they very clearly stated that the 4G4A series will not support HT. I gather that they aren't going to release a HT-enabled BIOS update anytime soon

Damn, damn and damn. If I only would have known this a month ago when I purchased the motherboard :|

I got a Intel motherboard D845BG with the i845D chipset it supports hyper threading too!

About HT

after a lot of invetigation, it seems ALL CPU P4 Northwood says "HT Ready" on 850,850E,845D,E,G,PE, and SiS645,645dx and 648 (even with a "non HT bios" for those who officialy support HT). More, Willamette CPU reports "HT enabled" in cpuid too !

the information read by CPU-Z or WCPUID doesn't come from the chipset but from the CPU itself. It sounds like a glitch or something else "trace" of an implementation of HT ... don't know how to say in English

so, don't be so happy ... normally your p4b533-v will never support HT (exept if Asus continues this production, but with B stepping chipset).

 

[Intelman07]

I got a willamette core and it says it supports HT! what is up with that!

 

[lookin4dlz]

from what I understand, ALL P4 chips have HT built-in, it's just not in its final form (so it wouldn't be as fast as "real" HT chips) & it's not enabled...
