Hello!



I have tried to use an EE 3.73GHz HT 1066 (04b) in a P5P800. Asus says
that bios 1011 is needed for 04b type CPU.
Obviously there is an other (lower version) BIOS installed.

Sometimes it beeps (prolonged) and then nothing. Tried to connect a PCI
VGA.... nothing..
How do I get the 1011 Bios flashed, without having a P4 which is
working with older versions of the BIOS :-) ?
Any help is appreciated!


By the way, can someone tell me how I get a second AC-Adaptor
(ATX-24pin) running? I have just this one MB installed. We would need
it, to get the GfX (350W) with watercooling run. The second (first)
AC-DC is just for MB, CPU and the rest of needed devices, except GfX...
it works when connected (standard) to the main-power socket of the MB.
Should I make a wire from (I think pin8 PS, powerswitch) the
Main-Connector to the second Adaptor, that it interpolate to get ON? Do
I need the PW-pin interpolated, too?

I thought in a previous thread, you were looking at the
(non-existent) P5P800 SE ? Then an Asrock board ?

I take it this is the processor you have bought ? I think
this one resembles a 660, as they have the same CPUID.
http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7Z4

sSpec Number SL7Z4
Processor Frequency 3.73 GHz CPUID String 0F43h
Package Type 775 pin PLGA Core Voltage 1.25V-1.388V
Bus Speed 1066 MHz Thermal Guideline 115.0W
Core Stepping N0 Thermal Spec 72.8°C
L2 Cache Size 2 MB Manufacturing Technology 90 nm
L2 Cache Speed 3.73 GHz Bus/Core Ratio 14

The only Extreme Edition listed for the P5P800 is this one

http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7RR

sSpec Number SL7RR
Processor Frequency 3.40 GHz CPUID String 0F25h
Package Type 775 pin LGA Core Voltage 1.25V-1.400V
Bus Speed 800 MHz Thermal Guideline 109.6 W
Core Stepping M0 Thermal Spec 66°C
L3 Cache Size 2 MB Manufacturing Technology 0.13 micron
L3 Cache Speed 3.40 GHz Bus/Core Ratio 17

This is the CPU support listing for P5P800:

http://support.asus.com.tw/cpusuppo...px?type=1&name=P5P800&SLanguage=en-us&cache=1

"P4-3.40 GHz Extreme Ed. (800 FSB, HT, LGA775)   ALL ALL"

That is the only EE processor listed, and the listing says
any BIOS "ALL" will work.

To see some lists of processors and their CPUID codes, I
started with this page:

http://www.intel.com/cd/channel/res...ors/int_inst_info/proc_comp_charts/188734.htm

I don't know where you are getting your information ? If the
3.73 is indeed similar to a 660, then BIOS 1007 should be
enough. Or if it is more like the 670, then BIOS 1009.

The 660 is SL7Z5 and the 670 is SL7Z3
http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7Z5

Considering the money you've already spent on this project,
I'd go to www.badflash.com and get them to program a new
BIOS chip for you.

As for running power supplies in tandem, all you need to turn
on a power supply, is the PS_ON# signal on each connector.
You could connect the PS_ON# from both power supplies together,
and turn them both on via the motherboard. Using tandem power
supplies is not something I would do with my own equipment!
A proper single supply is safer, as you never have to worry
about sequencing issues.

Pg.29 shows the pinout of a 20 pin ATX power connector.
http://www.formfactors.org/developer/specs/atx/ATX12V_1_3dg.pdf

The total power of this power supply may be enough to power
all of your toys, but the way the power supply is wired may
not be exactly what you want:

reads 04B, it should work.
So I thought it might not work, bez 1011 BIOS Update describes that it
has updated CPU support ....

I don´t know, for me all Pentium are the same. But as I saw very much
3.4 EE called 660, I would guess the 3.73 is a 670 and the installed
BIOS is a 1007. If it is correct, that the 670 needs at least 1009.

I had the same problem. None of the usual BIOS flashing methods would work
and I got an error message saying that no valid BIOS image could be found.
Pretty frustrating!

I finally managed to get it to flash by booting from a floppy using the
EZ-Flash utility (see section 4.1.2 of the manual)...be sure to rename the
BIOS file "P5P800.ROM" (without the quotes). Good luck.

You should always check the cpusupport web page, as it tells exactly
what has been tested, and what BIOS is the minimum version. As
for the electrical current rating of the Vcore circuit
(the 04A, 04B thing), virtually every Asus board does that.
I cannot think of any Asus boards off hand, that are 04A only.

Always look here:

I'm hoping your friend is a tolerant, forgiving person :-)

The 3.73GHz/FSB1066/2MB cache processor has a multiplier of
3730/266=14. You will not be able to change the multiplier,
unless the processor also happens to be an "ES" engineering
sample. Consider what will happen when you use it on an
FSB800 motherboard - it will run at 200x14, if you run the
motherboard at its nominal speed. You would need to overclock
to 266Mhz, to get the full speed of the processor. At
somewhere between 200Mhz and 250Mhz, you are going to see
corruption of the image coming from the video card.
Read this thread thoroughly, to understand what to do.
(You will need to try the 5:4 or 3:2 memory dividers, to
try to fix it.)

I think a 3.8GHz/FSB800/2MB cache processor (a 670) would have
been a better choice for use with the P5P800, as it will run
at 3.8GHz using FSB800 stock speed. No video artifacts are
to be expected with the use of a 670.
Thank you very much!

To connect the two supplies, some GND connections should be
made between the power supplies. Then, connect the PS_ON# of
one supply, to the PS_ON# of the other supply that is connected
to the motherboard. The supplies should come on simultaneously,
for least trouble (and since you have two identical supplies,
that is even better).

Here is an example of the problems you can have using two
power supplies - you have been warned...

Here is an example of connecting a second supply. There is
no explanatory text given for this picture:

I would have expected a very much heavier duty connection as the two PSU's
have to equalise there total current flows to the point of origin - if you
get what I mean. IE if psu 1 is loaded to 200w and psu 2 isloaded to 100w,
then the current for the 100w difference will have to flow over the black
wire right? = hot black wire, melted mess, big explosion....

Thanks.

That would be fine. But the system won´t start with the CPU we have. So
we would need an older P4 which is working with the pre-installed BIOS.
Then we can flash to 1011 and try the EE.

Of course, the EE would not run with Full Clock, it would run with
2,8GHz (200MHz-RAM 2225 DDR, dual channel, 1GB Total). Pretty much MHz
;-) for any decent game or so.

But maybe this Type of EE we have, won´t run at all in a i865PE (P5P800
Ai Edition), who knows? Or, it won´t let underclock to 800FSB :-( !?
I can remember trying 66MHz with an Tualatin, the system did not post
any more. With 75MHz FSB it begun to work, up to 133MHz (166Mhz FSB
overclocked also works), of course.

If so, it would be very bad news. He would have to sell the P5P800Ai
and the GeForce 6800 Ultra and try to get a i9xx Chipset with 266MHz
BUSspeed and (only) PciX, to get the 3.73EE working.

I agree that their implementation is just stupid. It was meant
to illustrate connectivity. The wire gauge is way too small for
the GND.

+--------+ +--------+
| | <--- sneak --- | |
PSU Load path Load PSU
#1 #1 #2 #2
| | | |
+--------+---------------------+--------+
--- return --->
current

The "sneak path" here, is the digital logic signals
that traverse the two power domains. One would hope the
resulting return current is of small magnitude, but I
agree that at least one 14 gauge wire joining the grounds
would be a minimum.

----- PS_ON# PSU #1 GND ----+
| |
| |
| |
Motherboard >--------+---- PS_ON# PSU #2 GND ----+
PS_ON# |
Motherboard |
GND -------------------------------------------|

I would splice one or more wires, between GND on the two
power supplies. Splicing PS_ON# together on the two power
supplies, will cause them to turn on simultaneously, which
is the best you can hope for, in terms of sequencing. As that
thread I linked to points out, it is possible to damage
equipment by using two power supplies, especially if they
are manually separately switched. The "sneak path" illustrated
above, is one possible path of destruction, if only one
of the power supplies is energized. (Also, imagine what
happens if the user forgets to switch on one of the PSUs
at the back, before using it. The destructive test case
could still arise, even with the PS_ON# signals spliced
together.)

The above wiring assumes the motherboard PS_ON# driver can
sink the switch on current on the two PS_ON# signals on
the power supplies. The ATX spec says the current is 1.6mA,
so twice that is 3.2mA. The motherboard _probably_ has a 10mA
driver for PS_ON#, but I have no way to verify that statement.

As I said before, I'm not in favor of running PSUs in tandem,
but I assume Daniel is going to do it anyway :-) The "sneak
path" shown in the diagram at the top of this posting, is
what I would worry about the most - the "sneak path" is at
its worst when only one of the two PSUs is turned on. Might
as well try to use the best configuration you can, if doing
a bad thing.

Note - You cannot connect +12V from one supply, to the +12V of
the other supply. Same for any other power outputs. That will
cause loop currents of large magnitude to flow as a return
current between the supplies, and will manifest itself with
either smoke, computer instability, or both. Current sharing
is a feature only available on PSUs intended for redundant
operation.

Here is an example of a redundant power supply, where when
both units are present, they share load current equally:

The least load of a floppy drive should do well for the slave-PSU.


Well, I will cut the wires from both and connect PS_ON and COM (Pin14 -
Pin15/16/17) together.

http://pc-mod.com/articles/atx/atx5.jpg


They will go to the limit. As we calculated 350W for the SlavePSU (GfX)
and 300-350 W (EE and the rest) for the MasterPSU.
Much cheaper than a 800W PSU!


Thanks again.
