Windows 7: RAM-Related BSODs, Several Times / Day

14 Sep 2010   #31

Windows 7 64-Bit

Hi Karl and Dave - thanks for sticking with me through this. You are the only reason I've achieved this level of stability I currently have.

Karl - the problem is exactly as you described. I've tested all the sticks individually in the one known working slot (the one I'm using now), and each of them check out for at least a full nights MemTest-ing. I'm pretty sure I have one bad slot, because one of my working sticks failed in only that slot. However, I only need / want two working memory modules, so that I can run at 4 GB. The G Skill memory I'm running is on the compatibility list for the IN9 32x Max, so I don't think it's that

Dave - I'm pretty sure that Slot #2 is bad. I've tested a few chips in there, and they all almost immediately give me thousands of errors. I know this board is on its way out - I would just like to graduate college before having to replace it, because I'll probably just get a brand new machine from top to bottom.

As for adjusting levels on my BIOS - I am totally game. Here are some of the data you asked for:

First, as you all suggested, I went back to defaults and the RAM timings are retrieving the auto settings (5-5-5-15) now. For one stick, it's completely stable.

CPU Core Voltage: 1.2625 V
DDR2 Voltage: 1.850 V
NB Voltage: 1.35 V

Also, I've attached some pictures of the SPD tab in CPU-Z and of SpeedFan running while relatively idle.

Under load, the GPU runs at just under 60C, and the CPU never goes over 40C.

Seriously, though, thank you all again so much for helping me out through this whole thing. You guys are great.

First clear your CMOS, check page 1-4 of your motherboard manual.

Might as well replace the CMOS battery, just to rule it out, page 1-5 of your MOBO manual.

Then Post the CPUZ, CPU and Memory tabs.

Check your BIOS and post the voltages again, clearing the CMOS can change them.
CPU Core Voltage:
DDR2 Voltage:
NB Voltage:

Then we'll go from there.

Thanks again for the help Dave!

I cleared my CMOS again. Same settings and voltages though - I did it only a few days ago as well.

Anyway, here are the new screens from CPU-Z.

You should have the RAM cards in slots 3 & 4, when running these two card tests, as you've mentioned the failures with any card in slot 2.

To confirm, when you're running with one RAM card in slot 1, 3 or 4 it's stable, correct?

With one RAM card in slot 3 or 4, set your NB voltage to 1.4v, check for stability.

If stable, add one more RAM card, these should be in slots 3 & 4.

Check for stability.
If stable, run memtest86+ for 7 passes or overnight.

Let us know how it's going.

Hey Dave - unfortunately the NB bump didn't seem to do it

The system remained stable with only 1 stick in, but once I added the second into slot #4 it wouldn't even boot to Windows. When I MemTested the 2 stick setup, there were thousands of errors within the first hour.

Should I bump it up more?

Yes, bump your NB to 1.45v and test for stability again.

If you get errors, you can stop the test.

Can you D/L Real Temp and post a snip when the temps level off.

Hm, a new type of error this time. I bumped up the NB to 1.45 V. Now, while it's trying to boot to Windows, it crashes to a black screen and tells me that my winload.exe is missing or corrupt.

Could this really be an issue? Why would it not be corrupt when there's just one stick?

First run check disk with the /R parameter .

How to Run Disk Check in Windows 7

If that doesn't help then it's a master boot record (MBR) problem.

Follow this information.

How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows Vista/7

Try these first:

bootrec /ScanOs

bootrec /FixMbr

bootrec /FixBoot

Let us know if it repairs the MBR.

So, bootrec /ScanOs doesn't find anything, and the /FixMbr and /FixBoot actions complete in milliseconds and don't seem to really do anything. Somehow, the problem seems to lie elsewhere. I booted into Safe Mode and rolled back some Ethernet drivers, and found it to solve some degree of these black screen crashes blaming system files.

Also, I did some reading elsewhere about the 680i boards being very finicky with lots of RAM. So I re-tested NB 1.4 v with a tRFC of 60. This time, the machine booted into windows, and actually gave me about 10 minutes in the computer before it crashed (0x00000050 - Page Fault...). Does this improvement mean anything to you, Dave?

I'm not sure what to make of this all, other than my board is seriously outdated. Still, I'd love to breathe that extra few months of life into here before I have to ante up and buy a new system altogether.

Run the system file checker, this tutorial will explain how.

If that come up with errors found but can't be fixed, then do a Startup Repair.


This is likely due to some memory connected to your computer. Could be RAM or USB memory stick.

Have you added any USB memory sticks to your computer recently?

If you have, remove all USB devices, except keyboard and mouse, see if the crashes continue.

Bump your DDR2 Voltage to 1.95v.
Check for stability.
You can keep the NB at 1.4v, if not stable bump NB to 1.45v.
If still not stable, bump DRAM to 2.0v and check for stability.
If not stable, bump NB to 1.5v.

We're trying to get your RAM to run on a quite possibly failing motherboard.
There is no telling how long it will remain stable if it actually ever becomes stable.

If the above fails to result in a stable system, you might need to confirm some of your componets.
Do you have access to another Graphics card and PSU?
Relace these one at a time and test for stability.
There is a chance one of these could be causing the crashes.
