BSODs with loud humming noise only during gaming ever since the installation of new RAM sticks

Hello all,
(Long post warning)

My older 4GB G Skill Ripjaws had developed some errors. So, I bought a new kit of 8GB G Skill Sniper. Both of them are 12800-CL9.

The older RAM sticks even though had developed errors, only used to cause BSODs randomly once in a week or so. Web browser crashes were frequent though.(Related thread http://www.tomshardware.com/answers/id-2012944/inconsistent-errors-memtest-bsod-frequent-app-crashes-manual-memory-configuration.html)

Anyway, when the new sticks arrived, I removed the old ones, did some name sake cleaning with a blower bulb and installed the sticks in slots 1 and 2. (The older sticks which were removed were in slots 3 and 4 since a few months.)

Memory config


After I installed the new sticks, ran Windows Memory Diagnostics, no errors.
Ran Prime 95 for around 45 minutes, no errors.
Ran a windows based memory test tool, no errors.

That night, I ran Counter Strike Source, PC crashed with garbled screen and loud buzzing noise. PC either froze at the garbled screen or the garbled screen proceeded to a blue screen and then froze somewhere during memory dumping process. This happened every single time within 15 minutes of running the game. Even when the PC froze, the PC outputted continuous humming/buzzing noise through the speaker.

Ran memtest 86+ for 10+ hours, no errors.

My Radeon 5770 died a few months ago. So I have been gaming with my on board Radeon HD 3300. It has 128 MB sideport memory(dedicated). The board allocates some 256 MB more from the system memory. 7.75 GB out of 8 was usable. I thought the errors may be in the addresses allocated for the GPU. So I forced the GPU to use only 128MB of dedicated sideport memory. All 8 GB became available.

Then I ran memtest 86+ for all 8 GB for 8 + hours, no errors.
Reinstalled GPU drivers twice.

Today I tried playing Counter Strike Source and Driver San Francisco. Both the games crashed with similar behavior.

I then removed the new sticks and reinstalled the old sticks in slots 1 and 2, same crashes in games.
Installed in slots 3 and 4, same crashes. (This type of guaranteed crashes didn't occur before installing the new sticks)

The crashes with the new sticks occur only during games.

The only cause that I could think of is that the slots might have got a lot of dust settled in them when I blew air as part of name sake cleaning. But if that was the case, the errors should have been picked by the memtest right?

What could be the problem? Please post all the solutions which you can think of.

Thanks for going through the long post.

  1. You were getting crashes before, right? You changed memory and you're still getting crashes. Maybe it's your motherboard. Maybe the memory type isn't fully compatible with your motherboard. Looking at the test report from MSI it looks like most of the tested, or at least successfully tested memory were either 1GB or 2GB modules. I see only a couple of 4GB modules, and none in the speed you're using. I'm not saying it's impossible for something not on the list to be able to work, but it's a good place to start. How long have you had the motherboard?

    Thanks for the reply,
    Here's some history of this PC:
    The board along with the other components of the PC was bought in June 2010. I have had the 2x2GB sticks ever since. I also had an HD 5770. I used to play a lot of games. The PC used to work fine for more than 3 years. RAM too was fine.
    The RAM started to throw problems somewhere after August 2013. Most of the programs that used high amount of memory started crashing(like web browsers) not just games. But those programs were only crashing to desktop, I wasn't getting BSOD frequently. Memtest also started showing 100-150 errors.

    The earlier crashes(ever since Aug 2013 and before buying new RAM) used to happen randomly. BSODs occurred only once in a week or so and it was completely random(not just in games). I could play CS:S and other games for more than 4-5 hours continuously most of the time.
    But ever since I installed the new sticks, crashes happen only when gaming, that too every single time, everything else including stress tests runs fine with zero crashes.
    Now the crashes happen in games(guaranteed) even if I remove the new sticks and install the old ones. Games crash every single time.

    I'm not sure about the compatibility, but G Skill's page for my RAM sticks listed my motherboard in the list of compatible ones.


    I noticed one strange behavior,
    I ran Counter Strike Source in windowed mode and joined in as a spectator and let it run in the background. It ran fine for more than 3 hours without crashing even once. But if I start to play the game in full screen mode, a crash within 15 minutes is guaranteed.
    I also ran furmark in windowed mode twice,
    During the first run, I had let it run and had gone to take a shower. By the time I returned(around 30 minutes), the monitor had gone into sleep mode. But the PC was on and was not responding.
    I ran it one more time for about half an hour. It didn't freeze.

    The main thing to highlight here is, I was able to play games without any guaranteed crash before opening the case for installing the new RAM. But ever since I installed the new sticks for the first time, the games crash within 15 minutes for sure no matter which sticks I run, older 4GB or new 8GB.

    Has my IGP got damaged by any chance?

    I'll play CSS in windowed mode and run furmark in full screen and report back.

  3. Here is our guide for DDR3-1600:

    http://www.gskill.us/forum/showthread.php?t=7688

    Also, make sure you have the latest BIOS for the motherboard. Updates are commonly released to improve compatibility.

    If you still have problems, try DDR3-1333 8-8-8-24 1.50V. These are fail proof settings that should work flawlessly any time.

    Let us know how it goes.

  4. Here's an update on the situation.

    In that same machine, I also have Windows XP installed as dual boot. I booted into that and started playing CS:S. I played for about 5 hours. In those 5 hours, the PC restarted only once (as opposed to freezing within 15 min everytime on Win 7) but no BSOD or freezing. It just restarted without any message. What sign is it? The driver installed in XP is an old 13.1 driver as opposed to the latest 13.9 in Windows 7.
    Can the driver be the problem? or is the issue getting masked here as XP utilizes only 3.25 GB out of 8 GB?

    Thanks for the link. Will follow that NB +0.10V.

  6. Okay, an update. After setting at 8-8-8-24, I booted into Win 7 and played CS:S for around 3 hours, no BSOD. Hope it stays that way. I'll update this thread either way.
  7. Try one stick at a time, maybe it is a bad stick?

    Also, which slots do you have them installed in? They should be in the same color slots furthest away from the CPU.

    Thank you

    In my mobo, there are 4 slots, DIMM 1,2,3,4. The slots nearest to the CPU are DIMM 1 and 2. They are black. DIMM 3 and 4 are away and are colored Blue. I have installed them in 1 and 2. Dual channel is enabled.

    BTW, the system seems to be stable at 1333 @ 8-8-8-24. I'm satisfied by that. I really don't find the need to run at 1600 since this rig is mainly used only for gaming and web browsing. Stability is the need for me at the moment. If I find any stability issues within a week, I'll post back. Thanks for the help.
  9. DIMM 3 and 4 would be less stressful for the CPU/memory controller, so you can try these for DDR3-1600.

    Then you can benchmark test DDR3-1333 8-8-8-24 in both sets of slots to see which one of these configurations performs best.

    Thank you
