Hello.I have a problem that i cant run my cpu in 3.2 Ghz , it only
runs in 2.8Ghz and i have intstalled the
latest bios version P4P800S-E Deluxe release BIOS 1006 but i cant find
any options in the bios to
change the clockspeed.
Do i have to install the 1005 file to , thats change the "Fix Prescott
Locked
CPU cant run to highest frequency. " ? or does the 1006 bios file fix
that to?

Latest BIOS is supposed to include fixes from earlier BIOSs. Maybe 1006 will
allow you to install SP2 on WinXP as well, so good idea.

When a bug is fixed in the BIOS, the fix should be carried into the
next BIOS release as well. I would try flashing 1005, as you suggest,
and then report the problem to Asus, so it can be fixed in the
next beta version.

This bug has to do with the "platform requirement bit (PRB)". There
are two levels of Vcore power design, and two power levels of Prescott.
The BIOS code has to do _something_ (dunno what exactly) to convince
a high power version of Prescott, that the motherboard is capable of
powering it. If the condition is not met, the processor is supposed
to reduce the multiplier to the lowest value for the family, which
is 14x, giving 2.8GHz operation. The BIOS fix should be adding code
to handle the platform bit.

If you are curious, look here. There are actually two different
versions of the 3.2E. One high power, one lower power. If you
report the BIOS bug to Asus, include the SSPEC (SLxxx) code
from the package the processor came in, so they can figure out
which processor you are using. (SL7B8 is high power or SL7KC is
low power - processorfinder.intel.com)

AHH, have you seen the claims/threads/news articles? that those new power
requirement Prescotts will NOT run on the existent base of 865/875 chipset
mobos. The claim is that there is a fundamental HW incompatibility that a
BIOS change can't handle! Massive googling might find it again as I don't
know where but the claim was very specific and I took notice. The claim did
NOT include the fact that there are two versions of Prescotts which I
assumed on reading it that there must be. This thread is the first place
I've seen confirmed two Prescott versions as I did no follow up research.

Further the claim seem to be that all faster Prescotts will be the higher
power version and therfore the Prescott faster CPU upgrade path for existent
865/875 chipset mobos is extremely LIMITED.

NOW let's make sure we get the two Prescott HW version issue fully CROSSED
with the SP2 microcode issue and BIOS microcode issue said:

Apparently it can't because it can't even if it wanted to said:

Interesting.

....didn't notice initially...Paul again...should have figured. Have you
heard about the issue I'm describing?
 
With respect to the OP, IF the claims I've reported are correct then you
need a different CPU if you have the high power Prescott version. Does
anyone know of a mobo that's guaranteed to work with the new high power
Prescotts...bet Intel has one but is it 865/875?

Ron, don't go tilting at windmills.

The OP can consult the cpusupport web page, for a list of processors
supported by his board. You can even select a particular processor
from a pulldown menu, and find out what boards support it (great
for shopping purposes). There is no need to read some old FUD postings
about 875/865 boards, to find out what is supported.

The issue I mentioned, is a BIOS only issue. If a motherboard only
handles the lower power version of the Vcore power spec, then that
motherboard's BIOS will not have to respond to the platform bit.
A high power processor mistakenly plugged into that kind of board
would run at low power, by using the 14X multiplier.

If the motherboard is capable of handling both specs for Prescott,
then the BIOS needs a bit of added code, to get a 3.2GHz Prescott
to run at 3.2GHz and not 2.8GHz. This small detail was brought to
the attention of the motherboard manufacturers at a late date, and
that is why a bug fix was issued just lately. This is a separate
issue from microcode, and the BIOS that introduced the required
microcode is a different BIOS revision than the one with the added
"platform bit" reading code.

The Vcore power supply spec has been around for a while, so there
won't be any surprises that aren't covered off on the cpusupport
web page.

Are you saying the above two articles are wrong/FUD??

Will a 3.4 Prescott run on my 3/04 purchased P4C800E Dlx at 3.4?

Those articles were written a year ago.
