Bios showing wrong CPU
ipleb
I have an Asus P5N motherboard with an Intel Core 2 Duo E4300 1.86ghz
Socket 775 FSB800 CPU. All was working fine ... until recently when I
installed an extra gig of RAM which put the system total at 3gig - the
PC runs Vista home pre.
Now I am not sure if installing the RAM did this or messing about in
the OC settings of the bios, but everytime the PC boots it halts at
the BIOS screen with a message sayinh.
"Unknown CPU detected, install latest BIOS to unleash Power"
Now I have the latest BIOS installed but the problem seems to be that
the CPU is coming up as an Intel Xeon 4812@1.6 ghz, 2 CPUs detected.
Vista also shows that an XEON is installed
Can anyone think why this has happened?
Thanks

Because you've been messing with the o/c settings?
Reset the CMOS and see what happens.

I'll give that a go ......

I've tried that - but no different. Still halting with Unknown CPU
error and also showing CPU as a Xeon
:S

Is the new RAM properly seated? Did you take adequate anti-static
precautions when fitting it? Have you tried removing it?

That is the next step - to remove the RAM
The computer has also started to not shut down properly
Everything was OK before the RAM so that is my next target.
Could the RAM affect the CPU type though, or at least alter the BIOS's
oppinion of what it maybe - say like if the new ram was a different
speed?

If you'd gone over 4gig I could imagine some buggy BIOS trouble, but
going to 3 gig should be absolutely fine.

If you updated the BIOS, the most likely cause is that the latest BIOS
is bugged.
Otherwise, you may have dislodged the CPU slightly so that one of the ID
pins isn't connected, but I'd hate to recommend reseating an S775 CPU.
Did you try removing the new RAM? It's remotely possible that the BIOS
switched to a lower FSB because it couldn't find a low enough divider
for the RAM.

Hi there
I will be removing the RAM as my next ppoint of call
Will let you know
Thanks

What does http://www.cpuid.com/cpuz.php show you as the CPU?..
If your FSB is set incorrectly then it's not uncommon for windows or even
the BIOS to confuse chips.

Hi there
I've just used the CPUID - it tells me I am running an Intel Xeon 5110
- a socket 771 lga package - weird as my mobo is obviously a socket
775
The core speed is at 1600 with a multiplyer of x8.0 bus speed at
200mhz and a rated FSB of 800mhz
I have two ddr2 533 pc2 4300 1gig chips and two ddr2 533 pc2 4300
512mb chips to give a total of 3gigs
The DRAM freq is at 266/7 and the max bandwidth of each chip is
pc2-4300 (266Mhz)
Most of that means nothing to me - does it help anyone else?
Oh and taking out the RAM makes no difference - I cannot remember
whether the problem started after installing the ram or upgrading the
bios
Can a bios be downgraded?

e4300 should have a 200mhz base (800mhz fsb showing) with a x9.0
multiplier..
if you are SURE you have a e4300 then you can try changing the multipler to
x9.0 (it should set to this on it's own unless your using manual settings)
FYI the Xeon 5110 is a part with a base frequency of 200 and a multiplier of
8..
Once you chang your mulitplier to 9 and reboot all should look well.

I've never seen one that couldn't be - just follow the same flash
procedure but with the older firmware file. Remember to reset to
defaults after.
In fact - did you reset the bios to defaults after doing the upgrade?
If not, try that first.

Hi there
in the BIOS setting for CPU configs - there is only an option to
change the CPU Multiplyer by either x6 x7 or x8 - I have tried it on
each and it seems to make no difference to anything - unless I am
changing the wrong thing. Alll of the others settings (AI Overclock)
seem to refer to the memory
I need to read up on Overclocking and clock speeds I fancy

The CPU multiplyer is (almost?) always locked by the cpu itself, these
days. Has been for about six years, since the original Athlons - and
there you had to bugger about cutting/relinking conductors on the CPU
itself!
Once you've got the CPU recognition thing sorted out, play with
ramping up the FSB speeds and the RAM speeds.
The "AI Overclock" will usually do all this for you, though - it's
just an automated "speed it up until it breaks, then back off a bit -
now speed up the next thing til it breaks, then back off a bit etc"
function. It should always do FSB, then optionally move on to other
things - perhaps that's what the options referring to memory are?
Better CPU cooling will usually give you higher stable clock speeds,
but sometimes it's not the CPU that's the limiting factor but some
other part of the FSB system so it may not help that much.

Multipliers on core2duo's are able to be turned down and not up..
This indicates to me that there's a limiter kicking in not allowing you to
go to 9 "are you SURE you have the e4300 ??"
Core2duo's can have the multipliers turned down (if you want to underclock).
Did you buy the processor from new?
Was it an intel original?
I only ask this question as the other options may require removal and
reseating of componets.
The only other option you have is to change the FSB from 200(800) to
225(900) but I dont know enough about your board and how the timings would
interact with the PCI/Memory frequency to suggest that.
Did the problem go away when you removed the ram?... Be sure to unplug the
computer and allow the caps to drain before removing/adding componets..
It could just be that the CPU isnt seated correctly or that the Bios has a
buggy CPU chart.. You saying that it will not allow Multipliers above 8
however makes me feel it's a bad seat.

It is definately an E4300 and was a retailed Intel chip. Had it for
some time now
The problem didn't go away when removing the ram. My usual system for
adding components is to turn off pc - unplug power cable - then press
the on button. There is a millisecond of life from the mobo until the
caps discharge. Then I touch a radiator to discharge my self lol
I did have a heck of a time getting the CPU fan installed - I found
the retaining clips on the 775 cpus a bit cumbersome so maybe I did
knock something.
After my nights I will remove fan and take out CPU then reseat it
Part of me is thinking - meh - just forget it the PC boots and works
ok - the other half of me is thinking - WTF is it?!? :D
mr deo
The HS clips intel provide are a but nasty, but you shouldnt need to force
them (just give a lot of time).. It could be worth reseating the processor,
or if you dont want to do that then try to move the fsb up to 225(900)
ipleb
I reseated the CPU (and fought with the clips hehe) no change - then I
changed the FSB (i think) to 900 but no difference noted
Is there going to be any problems if I just leave it as a Xeon
registered chip? The pc seems to run fine ... at the moment
