I have a pre-production 875pbz board and it has bios version

BZ87510A.86A.0009.B01

I downloaded latest bios update from intel, didnt work, tried stepping the updates, starting at p03, still doesnt update (even thought it says after the flash, it has) - anyone know what im doing wrong here? is there another version before p03 i need to step to?

I have the exact same issue as you with my preproduction 875PBZ. I'll try and flash it, it takes just a second as says that the flash is complete. When I check the BIOS rev, either in the BIOS or from CPUz it still shows P01.

Mine has a socketed BIOS chip that none of my retail 875PBZs do so I've considered trying to get a new chip from badflash.com or somewhere like that but haven't got around to figuring out exactly what chip I need so I haven't tried it yet.

Please PM me.

Hey people,

I just got my new computer together today after waiting a week for some Kingston memory that is compatable with this board.

I tried booting up, but I get the "cmos/gpnv checksum bad" message. I have then tried updating to latest bios, still the same error. It appears to be reseting to BIOS defaults as well every time it boots :-/ I am trying to disable USB 2, legacy, and boot, and relax memory settings.

I am running XP that was installed on another board (ASUS CUSL2 R.I.P...), would this cause this problem?

Any help would be much appreciated, cheers

More than likely. It's always best to scrub the disk and re-load the OS when putting in a new MoBo. Otherwise you're just asking for problems for a long time to come.

As I suggested to the guy on the previous page, any time you've got a brand new 875PBZ you should do this:

The very first time you boot up make sure you go right into the BIOS and set your memory timings manually. This board seems to have more trouble reading the SPD settings than most and usually sets them too fast, causing the system not to boot.

First, clear your CMOS, then go into your BIOS and set the memory timings to "manual" and some not too tight timings (at least until you find out how fast you can push your RAM), maybe something like 2.5-3-3-8 and see if it will boot that way.

Oh, and about your recycled OS, I agree with BillC that you should install fresh but that's not what's causing this "cmos/gpnv checksum bad" issue for you. This is happening prior to Windows trying to load, it's a BIOS-level issue.

Thanks people...

The error appeared AFTER the POST and AFTER i had to select "safe mode" or "normal startup" (as the O/S was booted a few times then shut down during my struggle to get the ASUS CUSL2 running again [which I didn't manage... another thread]).

Ok, so I am doing a fresh install, appears to be going ok so far... fingers crossed.

Recv the mobo, CPU/HSF and etc. today. When I installed the CPU I noticed the absence of Thermal Paste/Pad on HSF. Nothing in the box as well. However the HSF seemed heavy duty and had a nice copper shim.

I'll do the complete mobo swap in the next day or so.

Question:
Do the newer CPU (3.0c/3.2c) retail packages provide the thermal solution? Is it needed?

TIA

Patience ran out along with the wife's AMD Tbird today and I had to order a D875PBZLK today from NewEgg. Wish I could have waited to the newer revision boards but I think I will be alright as I will upgrade next when there is a new chipset and newer slots for a higher speed Prescott.

If nothing else, I can always upgrade to a 3.2D Extreme CPU

NewEgg had a sale on the 3.0c's today so I got that.

Is there anything special I should know about the installation of the mobo? I done swaps a few times before and something escoteric always popped-up!

Looking fwd to the upgrade and I'll submit my two-cents on the board and IDCC when I am done.

TIA

Intels stock heatsink for those processors is excellent IMO. Just look at it. Hefty copper slug with an intricate maze of deep aluminum fins. The only problem I see with them is they may, may not have the factory fan turn into a noisy fan after use. Also I think you may achieve better thermal conduction using a name brand paste such as Artic Silver 3 or 5 instead of the pre-attached pad already on there. You are pretty much stuck with the stock fan if you use Intels heatsink, I have seen adaptations to other name brand fans on a stock Intel heatsink but it wasn't pretty. The 3.0 comes with thermal paste in a syringe, the 3.2 comes with a thermal pad attached.

Edit:spelling

Sandog:

The 3.0C package I recv had neither a pad attached or syringe. My older 2.6A came with a lighter-duty HSF with pad attached.

I have a feeling later revisions of the 3.0c HSF with the copper shim negates the use of paste. I'll light it off in a day or so and see how the temp is.

Thats strange if it was a retail boxed processor. You should rub in a good quality thermal paste on the heatsink and the top of the processor to fill in the microscopic pores. This will prevent air barriers which air is a good insulator. Use your finger in a fresh sandwich bag and smear a drop around till you have a light haze and wipe with a clean lint free rag.

[JimTram]

Sandog thanks. I looked again in the retail box and nothing. I like the copper shim on the HSF - it leaves a good footprint on the CPU.
The CPU was boxed in July 17, so it may be a later revision HSF which includes the copper shim for enhanced conductivity?

This is a follow up to a problem I had when trying to update the BIOS on my D875PBZ. The board came 2 weeks ago with P05 on it. I put this thing together (my first ever), and then tried to update the BIOS from P05 to P16 using the Express flash on Intel's website. My computer did not reboot on its own, I did however wait almost 15 minutes, just to be safe. Intel said to power down, reboot, and flash again. This I did, it then gave me a successful update message. After that I have not been able to get into the BIOS since. I don't have an F lock on the keyboard, so thats not it. I've tried the F2 key and delete key. I've set the jumper to configure, (pins 2 and 3), normal, (pins 1 and 2), and even tried it with no jumper. Intel just responded to my e-mail by telling me to set aside my USB keyboard, plug in a PS/2 keyboard, hit F2 to get into BIOS, hit F9 to restore BIOS default settings, reset any custom settings, clear all DMI event logs, and reset configuration data. I just got done trying all of that as well. No luck, no getting into BIOS. No matter what keyboard, jumper setting, or key I hit.
Am I making a mountain out of a mole hill or what? I just replied back to Intel(with e-mail) for another suggestion. Any of you guys ever get this screwed up on your first build?

[JimTram]

On my first build I screwed-up a BIOS update, but that was the least of it. I finally RMA the mobo.

Did you make a BIOS restore disk? That save me a few times!

Did you do the update off the Intel site or did you save the installer to disk? I never update the BIOS from a website I just save to file - pull the plug on the internet, install and pray.
Try to update with a newly saved update file a few times more. Once it took me 6 tries.

Do not get discouraged - I am sure someone with more experience may come up with something.

Keep us informed. Good luck.

Try this. Pull the power cord from the computer. Pull your CMOS battery out for 30min. Put it back in and reboot. If it doesn't come into bios then try pulling the power cord again and pull the BIOS jumper completely off. Stick a floppy in with Recovery BIOS P05 on it and reboot. It should read the floppy then shut down and perform a series of beeps. When finished reboot again. Good luck.

O.K. Jim, thanks for the reply. I updated by downloading the file off the net to my harddrive, then getting off the net, shutting down all applications, and running the file off of C drive(Intels Express install Wizard).
Thanks for your reply as well Sandog. While I'm waiting to hear back from Intel, I'll pull the power cord and battery, and try that route. I have no recovery P05 floppy, is that something I can make with a floppy and Intel's website? Looking forward to seeing your pics on your new case Sandog! I definitely appreciate this gigantic thread and Ralf Hutter for turning me on to it!

Do a few scandisks while your waiting also.
