MSI Motherboard says that ram is bad after applying overclock.

I have a MSI A75a-G55 (Old Board, I know) with an AMD A6-3670 APU, I am trying to overclock it. I have a Cooler Master 212 EVO on it, and with AMD's Overdrive Software I can get it to 3.3 ghz without much worry, and my temperature stays anyway from 18 C to 50 C depending on what Im doing. But when ever I try to go into the BIOS and set up the Overclock from there, after I apply the overclock and reboot my mobo just gives me the beep code for bad ram. If I re-seat the ram it will boot and say the overclock failed. I have tested the ram and they are all still good. I'm really confused. Thanks in advanced!

My Specs:
AMD A6-3670
MSI A75A-G55 (MS-7695)
NVIDIA GeForce GTX 950
16 GB Ram 4 Sticks

  1. You should reset everything to default. Then go into BIOS and set the ram clock and timings to those advertised on the sticks. Then proceed with manual overclock of CPU from the BIOS. Don't use overdrive.

    I did this and it still had the ram error. It's really confusing

  3. Are you using identical ram or different types?

    I am using 2 PNY 4 gb sticks and 2 Kingston 4 gb sticks which have different frequencys from each other

  5. only keep one set of ram then clear cmos to see if it boot if not do the same with the other set .

    I did this, not change.

  7. could you memtest each ram module .

    That's no good. They need to be the same speed AND the same timings. otherwise overclock won't work.
    It's ok (not great or anything and I personally don't recommend it) to run two different brands/models with different frequencies and timings for standard PC usage as long as the timings are close because the frequency that all of your ram will run at is the frequency of the lowest speed RAM. When overclocking however this is not going to fly. they can be different brand/model but they need to run at the same speed and they definitely need to have identical timings. So unfortunately you are not going to have good experience trying to overclock the CPU, sorry.

    You can try this though.
    If you have the information available to you from either the packaging or the sticker on the RAM go into your BIOS and change RAM timings to the slowest set (this would be the set that has the highest numbers i.e.: 16-18-18-24 vs 14-14-14-24)

    Next adjust your RAM frequency to the slower set (this would be the lowest number i.e.: 2133 vs 2400)

    by doing this you might be able to get the RAM to sync properly and then allow you to overclock you CPU without the crash.

    If this doesn't work then you need invest into getting identical RAM.

  10. Apart from the facts mentioned regarding unmatched ram how exactly are you overclocking??

    That's the a6 3670k ??

    Meaning it has an unlocked multiplier.

    If you're overclocking via multiplier only you shouldn't have an issue .

    If for some reason you're altering the fsb clock speed (which you shouldn't be) that automatically overclocks ram aswell

    I am just using the multiplier in bios to oveclock my CPU, however I don't believe that it is the K model, but I read that it is still possible to overclock it so that could be causing the crash I guess, I will try changing the RAM settings when I get home. Also one of my ram sets run at 1.5v while the other runs at 1.65v would that be causing a problem too?

  12. Ok, So I'm an idiot. I was changing the core clock speed rather than the multiplier. My PC is up and running at 3.3 Ghz. I didn't have to change the ram settings at all. Does anyone know if my CPU is capable of running at a higher clock speed if I over volt it? Right now my PC is running at 10 C idle and about 30-40 C when under a load.

  13. if it work as is max voltage would not try it unlees you might want a new cpu did you try to raise the speed of ram to is max speed with xmp .

    I left the ram at auto right now, and I haven't changed my cpu voltage at all. Looking in my motherboard's bios I could not even find a vcore option, which I find odd. It has everything else

  15. use you motherboard user manual from page 3-11 to 3-14 to set the overclock for this board all the process is there .
