POST Code 0xB7 is a DXE (Driver eXecution Environment) Configuration Reset operation, which I don't believe has anything to do with memory. What is the exact beep code that you are getting? Describe what happens in exhaustive detail.
Barring getting nothing from your response, somethings to try are:
- Do a CMOS reset. Power off system, disconnect from A/C (unplug completely from wall), remove CR2032 battery for 15 minutes (minimum; yes, it *can* take this long to drain), restore battery and power back on.
- Attempt to power on with a single DIMM in the Channel A DIMM 0 slot. If it works, try adding more DIMMs. If it doesn't, move DIMM to different slot and try again. If you've tried all slots, try with a different (single) DIMM.
Hope this helps,
I'm a tech, have been for over 22 years, I already did all your suggestions before posting on these forums. I am STILL waiting for someone from Intel to actually answer my request for an RMA for this board as it is broken beyond belief.
Buying this board was a HUGE mistake, and I really wish I never did. I should have known when out of the box I had to flash the USB headers to make them work properly.
There are no beep codes when I have ram in the first slot, or if the slots are populated with known good ram, unless it is a stick of bad ram (which I keep for testing), then I just get the classic 3 beeps of no ram, same if there is no ram anywhere. When there is ram in the slots, whether it be 1 or 4 slots filled, all it does is boot loop with b7, the fans will start up, it will go through a few codes, then b7 reboot, and go over and over and over. The memory is 9-9-9-24 800 (1600) so it is well within the specs of the E5-2670.
Even on these forums there are posts of people with this same series of boards with this exact same problem. Intel DX79SI/TO Error 67 Boot Loop just as an example, and these are left unsolved.
The unit was working fine for 5 months, other than the fact that dimm slots 3-4 died within the first week, which again is an extremely common problem for this board.
POST Code 0xB7 is not directly associated with RAM issues. It is occurring in DXE. Problems occurring in DXE are driver issues - like the driver in the graphics card's OpROM hanging, for example. I am not saying this is the issue (it was just an example); it could still be something with the RAM (the BIOS and all drivers would be using it at this point)...
The minute you had the DIMM sockets fail, you should have had it replaced or returned - and TO is a *huge* step-down from SI. I should point out that this is a user-to-user forum and there is no guarantee that an Intel Customer Support representative will even read it. If you are serious about an RMA, you should be calling them. If you are in Canada (or U.S.A.), the number is 1-916-377-7000...
The fact that you test the PC with just one stick at the time with all 4 of them in all the DIMM slots indicates that it could be a problem related to the board or processor, since it is very unlikely to have 4 defective sticks.
Since the memory controller is on the processor, the problem could be related to the processor, or it could be a specific DIMM slot on the board that might be defective.
In any case the best way to make sure about that will be by swapping parts:
Do you have the option of using this same board with a different processor, or use the processor on a different board, same model if it is possible?
I know that option is not always available, but that will be the best way to find out.
Also, you do have 3 years of warranty on the Intel ® E5-2670 processor and on the Intel ® DX79SR, board, so we can always replace them for you, is just that if it is possible, we always recommend to make sure of what is the problem, since you for this case you want to replace the board and the problem might be related to a different component and basically we don’t want for you to waste your time replacing a part that might be working fine.
If you are interested in the replacement, in order to do that, please get in contact directly with us through chat, email, online support or phone support, here is the link to do that, you just need to select the type of product you are interested in replacing and you will get those options:
Well sadly, I got a replacement board today, 2 days late, thank you UPS, and the replacement board is doing the exact same thing. I have tested the processor in a gigabyte board, and the processor works fine, the ram works fine, tested in the same gigabyte motherboard. I have noticed that not only is their an error code b7, but also the memory init LED flashes like a strobe light when this error is occurring. I have also tried a different video card, same error. I have tried no video card, and I just get b0 and the good old beeeeeeeeep no video. The last time I had to replace and Intel motherboard, a DX58S0, I had to go through 3 replacements before I got one that worked and then I bought a gigabyte because I got sick and tired of dealing with Intel warranty as this was back when you had to call Tech support long distance before an RMA would even be granted. Is this why you got out of the motherboard business? Yes I know that is an uncalled for shot, but seriously, I should not be having these types of problems with an enthusiast class board, let alone be receiving a part DOA.
My current case # is 01073049. I am currently going on 12 days with a dead computer
As for a specific DIMM slot on the board, 3-4 died in the first week (like so many other owners of this board). If you try to put ram into any slot other than DIMM 1, the computer just gives the classic no ram beep.
Let me apologize for any inconvenience.
I am sorry to hear that the problem still persists.
Since the board is defective the option in this case for us will be to replace it one more time, but, if you do not want to go through that process again, and since you already have a service ticket number, we can always do for a refund for you so we can give you the money back.
I just doing a follow up on your case, and also wanted to find out if the problem related to the memory Ram still persists or if it was resolved.
Any questions, please let me know.
