OCCT


  • What is OCCT?
    • A program in the Shop App in the "Tools and Software" section
    • Stress tests CPU, RAM, and GPU
    • Useful to solve any BSOD (Blue Screen of Death)
    • Ensures that a PC is completely stable

  • OCCT monitors:
    • CPU Temperature
    • CPU Throttling - CPU downclocking due to insufficient cooling, which results in low 3D Mark scores and unhappy customers
    • GPU Temperatures
    • Power Draw - Wattage required by power supply.
      • Required wattage when not overclocking: CPU Watts + GPU(s) Watts + 30 Watts.
      • When overclocking, the system will require more wattage.

  • How to use OCCT:
    • Select “Infinite” to run without stopping.
    • Click “ON” to start the test
    • If it runs to maximum Power Draw, without any BSOD and without CPU throttling, then it is a stable system.
    • If you get a Blue Screen of Death (BSOD), then the system is not stable, and will need to be diagnosed. The rest of this guide will help you with that.
    • If the CPU is throttling, then the system will not perform correctly, and will need to be diagnosed.
Stock Settings for a Stable PC
  • In BIOS, use “Factory Reset” to reset the CPU/RAM values to factory values that should be stable.


  • In GPU Tuner, use “Reset to Default” to reset the GPU values to factory values that should be stable.
  • Note: If you have 2 GPUs that aren't the exact same model, you might have to use GPU Tuner to set Core Voltage to maximum to be stable, since one GPU is being clocked higher than its factory clock.
Blue Screens of Death (BSODs)
CLOCK_WATCHDOG_TIMEOUT
  • CPU Cooling failure
  • Check: Thermal Paste, Heatsink, Water Cooling setup


The system encountered an uncorrectable hardware error
  • Power supply failure - Insufficient wattage
  • Install a more powerful power supply, or use components that require less power.


A clock interrupt was not received on a secondary processor within the allocated time interval
  • CPU Overclock failure - Insufficient voltage for requested CPU clock.
  • Increase CPU voltage or decrease CPU clock.


Attempt to reset the display driver and recover from timeout failed.
  • GPU Overclock failure - Insufficient voltage for requested GPU clock.
  • Increase GPU voltage or decrease GPU clock sliders.
  • Note: If you have 2 GPUs that aren't the exact same model, you might have to use GPU Tuner to set Core Voltage to maximum to be stable, since one GPU is being clocked higher than its factory clock.
  • Tip: If you need a higher GPU Core Clock for a customer request, you can sometimes decrease GPU Memory Clock to get a higher GPU Core Clock.


The problem seems to be caused by the following file: uDisplay.drv
  • GPU Overclock failure - Thermal limit exceeded
  • Increase GPU/case cooling or decrease GPU clock sliders.
  • Tip: If you need a higher GPU Core Clock for a customer request, you can sometimes decrease GPU Memory Clock to get a higher GPU Core Clock.


PRN_LIST_CORRUPT
  • RAM Overclock failure - Insufficient voltage for requested RAM clock.
  • Increase RAM voltage or decrease RAM clock.

CPU Overclocking


  • Goal:
    • Find the highest CPU Speed that will run OCCT without getting CPU Throttling.

  • Required Parts:
    • AMD:
      • Motherboard: Any “real” motherboard (that isn't DFL or Mortoni)
      • CPU: Any AMD CPU
    • Intel:
      • Motherboard: Chipset must have “Z” or “X”.
      • CPU: Model must have “K” or “X”.

  • Concepts:
    • CPU Throttling (shown in OCCT)
      • CPU downclocking due to insufficient cooling, which results in low 3D Mark scores and unhappy customers
      • AMD CPUs: Thermal throttle at 95.5 *C (Note: Some like 3950X appear to use 100.5 *C)
      • Intel CPUs: Thermal throttle at 100.5 *C
    • Changing CPU Speed in BIOS:
      • Ratio affects CPU Speed only, and is recommended for simple overclocking.
      • Base Clock affects RAM Speed also, and is only necessary when fine tuning an advanced overclock that includes RAM.
    • Changing CPU Voltage in BIOS:
      • More CPU Voltage is required to keep the CPU stable while overclocking it.
      • PCBS BIOS warns about CPU voltages over 1.5 v.
      • You can always use 1.7 v safely for CPU overclocking.
      • If you increase CPU Voltage too much, you will break the CPU!

  • Overclocking Steps:
    • In BIOS, save a change to the CPU Speed and CPU Voltage, that you want to test.
    • Test in OCCT:
      • Is it stable (no BSOD), within thermal limits (no CPU Throttling)? Good. You may have additional headroom to try a higher CPU Speed.
      • BSOD: Increase CPU Voltage or decrease CPU Speed.
      • CPU Throttling: Increase CPU/case cooling or decrease CPU Speed.
GPU Overclocking


  • Goal:
    • Find the highest GPU Speed that will run OCCT without getting a BSOD.

  • Required Parts:
    • Any GPU can be overclocked
    • GPU Tuner will be used to control the overclock

  • Concepts:
    • GPU Tuner allows you to set the following on your GPUs:
      • Core Voltage % - Safe to change to maximum, since this is just a % offset value that is already determined to be stable by the GPU vBIOS
      • Core Clock MHz - Offset used to change GPU core speed, and is recommended for simple overclocking
      • Memory Clock MHz - Offset used to change GPU memory speed, and is only necessary for advanced overclocking
    • GPU Tuner controls:
      • Use the sliders to roughly change the values.
      • You can fine-tune up or down by a single value, by clicking on the “-“ or “+” buttons.
      • Be sure to hit “Apply” to apply any changes.
      • You can use “Reset to Default”, to reset the GPUs back to their default settings.
    • You cannot break a GPU by overclocking it.
    • GPUs have a thermal limit of 95.5 *C, so that is your target.

  • Overclocking Steps:
    • Run OCCT Infinite and watch GPU Temperatures.
    • In GPU Tuner, increase Core Voltage % to the highest value.
    • In GPU Tuner, increase Core Clock MHz, and hit Apply.
    • Test in OCCT:
      • Is it stable (no BSOD)? Good. You may have additional headroom to try a higher GPU Speed.
      • BSOD when GPU reaches a certain temperature: Increase GPU/case cooling or decrease GPU Speed.
    • Tip: If you need a higher GPU Core Clock for a customer request, you can sometimes decrease GPU Memory Clock to get a higher GPU Core Clock.
RAM Overclocking


  • Goal:
    • Find the highest RAM Speed that will run OCCT without getting a BSOD.

  • Required Parts:
    • Any RAM can be overclocked.

  • Concepts:
    • XMP (Extreme Memory Profile):
      • Automatically overclocks RAM Speed.
      • Recommended for simple overclocking.
      • Requires Base Clock to be set to its default value.
    • Changing RAM Speed in BIOS:
      • Use this to change the RAM Speed, in incremental steps that are defined by the motherboard.
    • Changing RAM Voltage in BIOS:
      • More RAM Voltage is required to keep the RAM stable while overclocking it.
      • PCBS BIOS warns about RAM voltages over 1.65 v.
      • You can always use 1.8 v safely for RAM overclocking.
      • If you increase RAM Voltage too much, you will break the RAM!

  • Overclocking Steps:
    • In BIOS, save a change to the RAM Speed and RAM Voltage, that you want to test.
    • Test in OCCT:
      • Is it stable (no BSOD)? Good. You may have additional headroom to try a higher RAM Speed.
      • BSOD: Increase RAM voltage or decrease RAM Speed.
Entire PC Overclocking


  • Goals:
    • Overclock the entire PC (CPU, GPU, RAM), for high 3D Mark scores and PC Bay values.
    • Get all 3 components at their temperature/voltage limits at the same time.

  • Concepts:
    • Use safe voltages so there is no risk to breaking a part.
    • GPU overclocking is the easiest to slightly change, so save fine tuning it for last.
    • As you test, take notes on which CPU/RAM speeds worked and which did not.

  • Overclocking Steps:
    • Setup:
      • Preset BIOS voltages to safe values: 1.7 v for the CPU, 1.8 v for the RAM.
      • Overclock the GPU to be close to its final overclock. Aim for 90 *C, since this will allow us a cushion to overclock the CPU.
    • Hunting CPU/RAM Speeds:
      • Try new CPU/RAM speeds, taking notes for each result. Test new speeds for both parts, at the same time.
      • If OCCT is stable, mark the values as "OK" and record the CPU Temperature.
      • If you got a BSOD, determine which part caused it, then record the Speed as "Bad" for that part.
      • Find the highest stable CPU Speed: ~0.5 *C less than the CPU Throttling temperature.
      • Find the highest stable RAM Speed: ~100-200 MHz less than a speed that would BSOD.
      • Once you know highest stable speeds for CPU/RAM, find combinations that maximize speeds for both simulatenously.
    • Finish:
      • Overclock the GPU, so it is the best speed that is still stable.
      • All 3 components are now overclocked to their limits.
      • Note: There is a bug where CPU temperature doesn't account for changes in GPU Overclock temperatures until the PC is restarted.
      • So, restart the PC to workaround the bug, and then run OCCT one more time.
      • Benchmark it using 3D Mark, and enjoy that Resale Value!

  • Example Notes:

    CPU
    5076 good 80
    5085 good 80
    5192 good 90.4
    5203 good 91.4
    5246 good 95.6
    5289 PERFECT 99.8
    5324 bad

    RAM
    4463 good
    4670 good
    4876 good
    5000 good
    5042 bad
    5083 bad

Yes. RAM overclocking increases 3DMark score. GPU VRAM Memory overclocking also increases 3DMark score.

Is there ANY purpose to RAM overclocking or memory overclocking (on the GPU)?

Nope. Also, is anything obsolete here? Thanks.
Peeetaaaa Jan 24 @ 7:07pm 
Would you consider putting "[OBSOLETE] " at the front of this guide's name, since I'm maintaining the "My name jeff" guide which has the info in this guide and more?

Who said anything about quitting. I accepted it but at the time I was debating on just storing the computer in the cabinet... though in the end I sent it back so the brat could get his computer for "video calls"
PUC_Snakeman  [author] Jan 17 @ 5:14am 
I highly recommend to NEVER click Reject or Quit, on a Story job, unless you are forced to.
Kaas Chuig Jan 16 @ 7:59pm 
Thanks. Thought it actually was supposed to be possible at lvl 9 but I guess not. Good thing I already bought that computer cabinet and there isn't an urgent notice.

... now to decide if I want to return the "Video Call" grandson's computer after the brat told his grandma I put the virus on it... debating on keeping that in the cabinet too.

Sometimes the job generator generates a job that is Dual-GPU, with models that are different, that requires either increasing voltage or decreasing clock. If you don't have GPU Tuner unlocked, you'll either need to hold onto the job until you can get it, or take the 1-star-hit by clicking Collect.
