ANY IDEAS WHICH P35 MOBO WON'T HAVE PROBLEMS BOOTING A PENRYN QUAD OUT OF THE BOX?

and i can tell you based on the opportunity i've had to try a penryn 9450 quad, it will not post on my gigabyte p35 9450. it's not a build issue as i went back and forth between my 6400 and the 9450 and the quad would not post at all..the 6400 everytime..fans start and that's it. it's not a ps , issue, the system has been running for 2 months flawlessly with the 6400. it was suggested as i'm on the very latest bios (F11) that i should try an early bios and that latest is not necessarily best..certainly sometimes the case for overclocking..but...

worst case scenario is that my board is not compatible and i'll have to buy a new one so alternately, looking for best suggestions..the abit p35 pro looks cool but i've never used an abit, don't know what to expect in terms of penryn compatibility out of the box🙂

 
there is always a chance of you getting an older bios with the new mobo you buy, and thus having it not compatible out of the box...
But from what you are saying you cant get it to work even WITH the latest bios...

Did you try the latest beta bios?
 
Gigabyte DS3R mobo has several revisions (1.0, 2.0, 2.1) and each revision has its own BIOS. When you download your BIOS from Gigabyte web site, make sure that you select the correct board revision number. Do not upgrade your BIOS via @BIOS (Gigabyte's window based bios update program) because @BIOS cannot distinguish different mobo revision number, hence you will not be able to determine which bios it is flashing onto your mobo.

They may very well be since they all have the same version number; however, to be sure that I'm flashing with the correct one, I would manually download the bios and flash it myself.
 
sorry..should be more clear..i have a P35 gigabyte ds4 rev 2.0 currently. it supposedly has had penryn support since about 3 or 4 bioses before the 1 i loaded (i'm using latest..f11 currently..i think about f7 or something like that it indicated 45nm compatibility and successive bioses have indicated further enhancements to that.

system wise, i have a 500 watt silverstone ps which is relatively new and has had no issues with my 6400 dual core at all or any of my equipment (1 hd in box, 1 cd burner, 2 tuner cards, 7900gs oc card at stock, sound card..offboard, usb printer, 2 usb hd drives, usb wireless nic.

what i did was removed my tuner cards, soundcard, nic, printer, external hd's in case it was a power issue even though i think that completely unlikely. still no boot..fans spins and it tries to reboot numerous times. put the 6400 back in, boots..put the penryn in ..doesn't put 6400 back in, boots..etc etc.

again, there was a suggestion to try an earlier bios which is likely my next step before trying another board. looking at the abit p35 pro if i can't get the gigabyte to go and hope it's simply a mobo issue, not issue with the processor itself which of course is an ES, but it's a B1 which i understand should be fully featured and version that would be supplied for any reviews and testing so you would expect it to work properly. i've been assured by the supplier that it booted up in their test system without issue (asus pk5 board i believe) but i dont' want an asus board. .and the processor itself looks fine.
 
The Gigabyte P35-DS4 Rev 2.0 board has Dual BIOS Plus. which means it has 2 Bios chips on the motherboard. Make sure that you flash BOTH bios chips with the same latest bios version. Here is what I suggest you do:


1. Install the Q6400 on your mobo and make sure that it is working.

2. Download the latest BIOS version for the Rev 2.0 of the GA-P35-DS4 mobo (F11) and extract/save it to your floppy disk. Make sure that you click on Rev 2.0 mobo and then click on "BIOS" to get the correct version. Here is the link to it.

3. Reboot your computer and go to the BIOS menu and select Q-flash. This will allow you to flash the BIOS from the floppy disk. Do NOT use the windows based @BIOS program to flash your bios.

4. When you're in Q-flash, make sure that you flash BOTH the bios chips (since your mobo has 2 bios chips). Flash 1 bios chip and then repeat the same procedures again for the other chip.

5. Reboot your computer again with the proper bios settings to make sure that your system is still working properly with the Q6400 installed.

6. Install the Q9450 into the mobo and see it will boot up.
 
thanks for the tip, doc..the other thing that i verified this morning, is that the boards default on all errors but keyboard was activated. i'm going to change that to halt on no errors as it may well need an inf update for the penyrn..so maybe cpu initialization error due to 45nm that i may be able to get through to update somehow past that point..i'll let you know how it goes. tomorrow, i'm going to bench test the penryn on an abit ip35 pro that is on the way to me so we'll see how that works out..if it won't bench on the abit or the gigabyte..then i'm going to have to assume the penryn is the issue. i believe the gigabyte is 4 layer board. i wish i knew if the abit was a 4 or 6 so i could eliminate or more clearly confirm that what we heard about the penyrn needing to be tweaked before release due to noise in the pcb on a 4 layer board is true? that being said, the penryn data sheets as recent as feb 1st, indicate no issue along that line so i've been believing that was a bunch of bs🙂
