Seeking urgent assistance (AMD AM3+: FX8350)
Seeking urgent assistance (AMD AM3+: FX8350)
Info:
My PC specs
Goal:
OC to 4.4 - 4.6 Ghz
Testing Software:
CPU-Z, Prime95, Speedfan, Core Temp
Overclocking Utility:
UEFI Fatality Professional 2.0 (latest version)
CPU Voltage:
stock (1.38V)
NB Voltage:
stock (1.20V)
Disabled UEFI (BIOS):
All power saving stuff except AMP as it's not require to disable it in order to OC even to 4.8 Ghz stable.
Experience:
None, watched some guides on youtube and luckily stumbled upon a video from JayTwoCents or something, showing the exact same CPU and almost same MoBo.
Issues:
Once overclocked to 4.2 Ghz, BSOD's every few mins and/or freezes, forcing me to shut down PC manually
Testing with Prime95 always results in a fail, even with the slightest change to 4.2 Ghz, without changing volts. (mostly 1-3 cores fail first minute)
I do not have Digi/VRM settings in my UEFI, which the Killer edition of my MoBo does have. So I lack CPU/NB callibration option, CPU Voltage buffer and NB voltage buffer( in %, mostly set 120 - 130%). I do have the normal CPU & NB voltage settings available (mostly used for OC) but I lack the special settings which most of the tutorials I saw were using. (due a version higher of Mobo, didnt found tutorial for my Mobo)
I have no idea how my CPU Ratio works (multiplier). I got this NB bus multiplier, which I dont know if it's the same as CPU Ratio. But when I take a look at it, it says x20 (4600Mhz).. Whats this 4600 Mhz suddenly, despite CPU Bus Frequenty is at 200. (200 x 20 = 4000Mhz = stock speed of my CPU) So this 4600Mhz confuses me. Also in stock setting, the NB Multiplier is set on x11 @ 2xxx'ish Mhz.. No idea the fuck this is and if this is the one I should be targeting. I have no other multiplier whatsoever anywhere in my UEFI so I figured this was the one I had to alter. CPU-Z does show a solid multiplier of x20 but no idea where it comes from.
My DRAM Frequency sometimes gets halfed. I normally have a total RAM speed of 1600Mhz, which is 799 Mhz Frequency. When trying to overclock to 4.2Ghz, my RAM frequency is halfed to 400Mhz (800Mhz total speed) while I did not touch it. I do know once changing the CPU Bus frequency, it all changes. But I always tried to stick close to the RAM provided. Although I still do not know if I need to enter the DRAM Frequency or the actual total speed of RAM in the UEFI (BIOS)
When trying to overclock to 4.4Ghz or more, all my USB/HDMI connected stuff doesn't get power anymore at the next restart. Which results in black monitor, dead mouse and keyboard while PC is starting up. This again forces me to manually restart the PC after waiting a minute. Then it changes everything back to 4.0Ghz and the USB/HDMI connected stuff works again (black screen with small white text showing it at starting up)
I have 0 experience in this and there seems to be no guide at all to help me out. My Motherboard and CPU are made to overclock yet cranking it up by 0.2Ghz is already making my PC fail everywhere where it can. I already tried AMD Overdrive but the same issues persists here aswel. Actually I first tried AMD Overdrive and thought it would be better to OC through UEFI.. But it doesn't seem to make a difference for me at all..
I'm sincerely afraid I've done any permanent damage to some hardware after hours of fails and restarts. I had 0 stable OC's while I barely touched anything.. I really would appreciate ppl to help me on this with guides, tutorials, self-experience, videos...
What I dont get is why experienced OC'ers call multiplier OC'ing easy because even that causes me problems for some reason. Stock volt (1.38v) and going x21 (4.2Ghz) is not even working for me. My Mobo and CPU should be able to handle this easily.. I seriously need help asap..
My power source and cooling system are internal components designed to function efficiently.
Your power supply and cooler details are listed in your PC specifications. The PSU is 650W and you have a liquid cooler for the CPU, along with one 4.2Ghz test rig after two minutes of overclocking. You mentioned experiencing BSODs and increased voltage to 1.4, followed by four failed cores after five minutes of testing. It seems unusual that you can't even reach 4.2Ghz.
Your power supply/cooler is still working but performance fluctuates. At 4.2Ghz it stalls at 4.1Ghz during testing, though core voltage returns to normal when testing stops. It seems Prime95 might be affecting stability by lowering core voltage. After adjusting settings and reducing the multiplier, only one core failed after several minutes. If a core fails slowly, it could indicate progress toward stable performance.
Hi and welcome to Tom's forum.
You're looking at an unlocked CPU, so the optimal method to overclock it is through the multiplier setting rather than using the FBS or reference clock.
What you need to understand is this:
FSB impacts all components of your system, including CPU speed, RAM, and PCI-E connections. The CPU frequency calculation depends on FSB.
For your CPU, the stock frequency is 200*20 = 4GHz.
From the image you mentioned, your HT is at 2500MHz; adjust it to 2000MHz using the "Auto" voltage setting. Repeat this for NB, setting it to 2000MHz with "Auto" voltage. For FSB, consider reducing it to 200MHz and press C1E to enable it.
Your CPU should reach around 4.2GHz naturally without any voltage changes. Enter BIOS, disable Turbo Core, C1E, and Cool'n'Quiet. Find the Multiplier option, change it to manual, set it to 22, press F10, and wait for the system to boot. Run the test again and share your results.
I think the problem might be related to the power supply. You shouldn't encounter any issues reaching 4.4/4.5 with the other specifications you mentioned.
I actually discovered the fix. My LLC (CPU Load Line Calibration) was causing my PC to be extremely unstable at all times. I attempted to lower it, but it remained unchanged. When I powered it off, the multiplier overclocking function worked smoothly, just like before. Now I'm stable at 4.3 Ghz.
However, after the numerous crashes earlier, I'm still having trouble opening any official Microsoft Office programs—they all display an error message :/
The issues you're facing are similar to what others have experienced with a different build. The socket 1366 works, but the power supply assessment is accurate—your PSU is incorrect, and the one you have is faulty. The PSU for the 1366 model was an Antec 1000W, not the problem; it's the PSU type that matters. Right now I'm using an AMD 8350 with an Asrock Faluty Extreme 9 M.2 and 16GB GSKILL RAM 4x4. However, I purchased a Corsair 850 AX PSU there, which I overclocked to 4600 stock cooling. It's time to get a new PSU.
