Repeated BSOD's Last 3 Days

goosegas said:

Dave-

The information I included in my last reply is all that I was capable of gathering.

I wasn't able to figure out exactly where I needed to be to change the RAM frequency and timings. Can you please help me to do that?

First, you will need to get the motherboard revision number. Open the case and look in the lower left hand corner of the mobo (mobo: short for motherboard), you will see a small circle, next to it will be the revision number. Example 'REV 2.2'.

Then go to your Gigabyte 870A-UD3 motherboard website, click the revision number you found on your mobo, it's near the top of the page, click the 'Download' tab and 'Manual' from the drop box, and down/load the mobo manual.

Read 'Chapter 2 BIOS setup' on page 33.
Familiarize yourself with the general layout of the BIOS, where the different sections are located, etc.
For example:
2-2 Main Menu on page 35.
2-3 MB Intelligent Tweaker(M.I.T.) page 37, this is where the RAM and NB settings are.

For future reference. Don't change any of these yet.
This is where you change the RAM frequency. Page 38

Set Memory Clock

Determines whether to manually set the memory clock. Auto lets BIOS automatically set the memory
clock as required. Manual allows the memory clock control item below to be configurable. (Default: Auto)

Memory Clock

This option is configurable only when Set Memory Clock is set to Manual.
X4.00 Sets Memory Clock to X4.00.
X5.33 Sets Memory Clock to X5.33.
X6.66 Sets Memory Clock to X6.66.
X8.00 Sets Memory Clock to X8.00.

DRAM Configuration, on page 38. This is where you change the RAM timings.

DDR3 Timing Items

Manual allows all DDR3 Timing items below to be configurable.
Options are: Auto (default), Manual.

2-12 Save & Exit Setup, page 55
Attachment 144480

These are just for knowing where to find things in your BIOS.
I will list the steps to be taken below.

Also, in regard to the CPU NB VID Control, are you saying that when it is set on AUTO, there is a value assigned that I can actually see, so I know what the next setting upward would be? If I do set it on manual, what number should I use, if I can't see anything more than AUTO as the current setting?.

All BIOS are not the same, some will show a voltage when set to 'Auto' and some will not.
If you don't see a voltage when it is in 'Auto' then change it to 'Manual' you should see a voltage, post it here.
If you still don't see a voltage, some BIOS's don't, there will be a choice of increasing the voltage, choose the smallest increase and post the voltage here.

Default 'CPU NB VID Control' is 1.1v, the option to increase should be (approximately) +0.02v.
Select +0.01v if available or +0.02v, then post it here.

Since we last talked, I reinstalled windows 7, to try to further eliminate the potential driver participation in the issue and provide more support to the RAM theory.

The computer went 24 hours without a BSOD, but in the last 2 hours I received 2. One said "Memory Management" and the event viewer info was exactly the same as in my original post. I wasn't able to read the second BSOD screen, as it stayed for only 2 seconds before the computer restarted itself..

This is typical for RAM voltage and timing issues that need an adjustment.

Since I did reinstall the OS, I have included a new zip file, part of which is the new diagnostic file.

I noticed that once again, at the very top of the diagnostic file there is a warning of some kind, but also information stating that there is no detection of antivirus software. That statement is strange in that Avast was not detected before the reinstall and now McAfee is not detected, although running, after the reinstall.

Please advise and thanks again for all your help Dave

Review the above sections in your mobo manual.

There is the known issue with AMD integrated memory controller not liking 1600MHz for RAM, will come back to this later if needed.


Let's try a 'CPU NB VID Control' voltage bump, and see if that will stop the BSoDs.

First step:
Change the 'CPU NB VID Control' to 1.15v.

If there is a senario that causes BSoDs then try to re-create it.

Results will show quicker if you run Memtest86 and Prime95 torture test - Blend.

RAM - Test with Memtest86+


CPU - Stress Test with Prime95

Let us know if you have any questions.



EDIT:
Is this your RAM?

ADATA 1600G

This appears to be Intel i7 RAM.
There are many know issues if trying to run i7 RAM on a AMD system.
Sometimes it works or can be made to work.
It is always better to get RAM that is specifically for AMD.

Keep this in mind, we should still try to adjust some of these settings. It is possible that it can run stable.

Your RAM timing are set loose, did you set these manually?
Your RAM XMP settings should be 9-9-9-24 according to the CPUZ SPD tab.

I found 2 things of interest. I do not know what they mean, so I attached it below. I have attached 2 photos of my screen. The first one is there to show you that where it says RAM Settings, the stick being tested reflects:

800 Mhz (DDR1600) / CAS 11-11-11-29 / DDR3 (64 bits)

A different stick was reflected as:

200 Mhz (DDR400)

Both sticks appear identical and have the same part numbers

Where did you see the '200 Mhz (DDR400)' reading?

Post the 'CPU NB VID Control' voltage, let's adjust this before anything else is done.

Good snips of the BIOS screens, this gives the information needed.

First thing to do is change the 'CPU NB VID Control' to 'Manual' and select +0.05v.
The -0.075v will cause the issues you are having.
There may be other issues but, this is where we need to start.
When you select 'Manual' the BIOS should show the voltage being used, post it in your next reply.

Run memtest86+ with all cards installed, 7 passes.
If you get any errors you can stop the test.

Where did you buy the computer?
It appears there have been some adjustments made in BIOS.
Don't see anything wrong, we can make a few adjustments to see if will run stable.

What were the details when the RAM card frequency that is showing 200 Mhz (DDR400) was taken?
How many RAM cards installed at the time the info was shown on memtest86+?
If a single RAM card, did it pass the test?

Second thing to do, if this was a single card installed and showing 200 MHz, use memtest86+ to check the reading (full testing not required at this point) of the same card again and post the picture.
If it does get the same 200 MHz reading, move it to another slot and check the reading again.
Then confirm the single RAM card reading with CPUZ Memory tab.

Your initial CPUZ Memory tab shows the correct frequency with 8GB installed. The above is just to varify. Some RAM 'Auto' settings can cause this to happen.

As with all trouble shooting, this could be a bad card or incorrect BIOS settings.

Let us know if you have any questions.

Glad to hear it's running better, hope it stays that way.

Change the CPU NB VID control to 1.15v now, and if you get another BSoD change it to 1.20v.

When you add the fourth RAM card, if you haven't already bumped the voltage, change the CPU NB VID control to 1.20v. This will let your system run stable, and is a safe voltage for your system.

The 'CPU NB VID Control' is the CPU integrated memory controller, this is the one that needs to be increased.

The second screen snip shows the amount of voltage you can increase or decrease the integrated memory voltage from the default setting of 1.100v.
To reach 1.150v you need to select the +0.050v option.
The voltage default setting is 1.100v, adding +0.050v equals 1.150v, this is what you want to acheive.

The second snip is showing the -0.075v option, default voltage is 1.100v minus 0.075v equals 1.025v for your integrated memory controller, this is causing/contributing to your problems.

Select the +0.050v option to obtain 1.150v for the 'CPU NB VID Control'.

Let us know if you have any questions.
