CPU error on new AMD Vishera pc build 3 beeps by motherboard.

I built an AMD machine that is nothing but problems. I've already change the cpu and still the three beeps are back.

Original Specs:
AMD FX-8320 Vishera 8-Core 3.5 GHz (4.0 GHz Turbo) Socket AM3+ 125W
G.SKILL Sniper Gaming Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866
Cooler Master Hyper 212 EVO - CPU Cooler with 120 mm PWM Fan
MSI 990FXA GAMING Desktop Motherboard AM3+

I never built an amd machine. This was the first one. The past three were intel. This computer post and I went straight into bios to update it and temps were 28-32C But it moved very very very slow and I had no idea why. I couldn';t uninstall programs. I couldn't even do the windows experience index. It acted like a ten year old prebuilt machine. I reformated it a few times in case something was wrong. Was it the hdd? the memory cards? etc

It took me a long time but I found out that the video card that I was using was defective and the cd would not install. So, I'm stuck with a DOA video card. I went over the specs and realize that the CPU was too hot. I thought that the MOBO can support any AM3+. I was wrong, I replace the AMD FX-8320 Vishera 8-Core 3.5 GHz (4.0 GHz Turbo) Socket AM3+ 125W with AMD FX-8300 Vishera 8-Core 3.3 GHz Socket AM3+ 95W

I removed the 125W cpu with ease. I literally just had to pick the heatsink up no resistance what so ever. Clean both the cpu and heatsink with alcohol like crazy. Install the 95W CPU and did a fresh reformat and everything was better. Added a new video card and the computer worked perfectly.

Now, a week later the three beeps returned? What should I do? Bios is uptodate and I reset CMOS. Memory sticks are fine I used memtest to test it.

  1. Something else is wrong there, MB is quite capable of using any Vishera processor and even OC them good. With properly cooled 8+1 VRM it can deliver 140W at least.
    If you are sure your settings are right, including CPU voltage, than I would suspect PSU or improper cooling.
  2. I thought 125w was fine. It seems that the board can handle it. Idk what can be wrong. What happen was the CPU temp jumped from 25-30 to almost 50c. So I replaced the CPU. Now I know the idea of a CPU going bad is minimal.

    Anyway I'm using artic silver five. I used the appropriate amount of thermal paste. I used the glove/ plastic bag method.
  3. Why don't you use AOD it will give you better idea of what's going on, There's Stability test and you can turn on Logging while doing it and see if there are some unusual peaks in temps or voltages.
  4. 3-beeps for post code indicates a Ram issue. Either it is not set properly in the BIOS or there is a compatibility issue with the ram.
  5. With the 125W cpu I actually felt heat coming out of the pc. The heatsink actually felt hot. After putting in the new cpu heat was less. In bios the cpu fan min is 25 to 100 percent max which was the default setting. With the 125W I didn't hear or see the cpu fan working faster?

    Idk, I made the cpu fan min to 85% and cpu temp was as low as 29C. That was the lowest and I also added a second fan for exhaust which help.

    I reset ram again and it's better no beeps. I know you are suppose to put in ram evenly. But this mobo is the one with only the lop latches. The bottom won't go in evenly if I put the chip in straight. about 50 percent in I have to push in the bottom and then the top.

    No worries pc is good now. but stuch with 125w cpu and a doa video card.

    If the video card was doa it should have been covered under warranty for replacement. If there was nothing wrong with the cpu then you're pretty much stuck with it. It can't be rma'd if there's nothing wrong with it and part of the gamble when it comes to replacing parts to solve the problem. Maybe try selling it and getting some of your money back out of it.

    Heat coming out of the back means the heatsink is doing its job. The cpu will produce x amount of heat regardless, either the cooler will get rid of the heat and blow hot air out of the back and keep the cpu cool or it will blow only a bit of heat out of the case and the cpu cores will remain hotter. Under load it will likely produce a fair amount of heat, it's an 8 core cpu. Twice as many cores producing heat as an intel i5/i7 and enthusiast 8 core intel cpu's produce a fair amount of heat as well. Performance equivalents aside, you still have a good number of cpu cores to keep cool.

    CountMike's suggestion to use amd overdrive was a good one. The way temps are read for intel cpu's and amd cpu's differs and amd uses a somewhat odd algorithm which makes it more difficult to accurately read their cpu temps. Overdrive typically does the best job of it and shows thermals as distance to thermal max so the higher the number the better. The lower the number doesn't mean lower the temp, it's reading how many degrees until it reaches the max. It's also easier to get accurate temp results from temps at load, at idle temps can vary widely and are typically less than accurate.
