   Verify:
   ├─> Speed: Should match RAM spec (e.g., 3200 MHz)
   ├─> Slots used: 2 of 4 (dual-channel)
   └─> If speed is slow (2133MHz when 3200MHz RAM):
       Enable XMP/DOCP in BIOS

4. Confirm GPU in correct PCIe slot:
   Open GPU-Z > Bus Interface

   Should show: PCIe x16 3.0/4.0/5.0 @ x16
   ⚠ If shows @ x8 or x4: GPU in wrong slot or bad connection

Running the Benchmark Test

Step 4: Access the Benchmark

1. Open your web browser: Chrome, Firefox, or Edge (latest version recommended)
2. Navigate to the benchmark website
3. Allow WebGL permissions if prompted
4. Verify GPU detection: Page should display your GPU name
   • If shows integrated GPU instead of dedicated: Browser using wrong GPU
   • Fix (Windows): Settings > System > Display > Graphics settings > Add browser > High performance

Step 5: Configure Test Settings

Typically includes automatically:
├─> Rendering Test (3D graphics performance)
├─> Compute Test (shader/compute performance)
├─> Memory Test (VRAM bandwidth)
├─> Particle Test (physics simulation)
└─> Feature Detection (supported technologies)

No configuration needed - tests run automatically once started

Step 6: Start and Monitor Test

During Test Execution:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

What You'll See:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Phase 1: Rendering Test (0:00-1:30)
├─> 3D scenes with increasing complexity
├─> FPS counter displayed (expect 40-200+ FPS)
├─> GPU usage should be 95-100%
└─> Temperature rising (normal)

Phase 2: Compute/Shader Test (1:30-2:30)
├─> Complex shader effects and computations
├─> May see lower FPS (compute-bound)
└─> GPU usage remains high

Phase 3: Memory Bandwidth Test (2:30-3:30)
├─> Large texture streaming
├─> Tests VRAM speed and capacity
└─> GPU memory usage increases

Phase 4: Stress/Particle Test (3:30-4:30)
├─> Intense particle physics simulation
├─> Maximum GPU load
└─> Highest temperatures typically occur here

Phase 5: Feature Detection (4:30-5:00)
├─> Tests for advanced GPU features
├─> WebGL 2.0 capabilities
└─> Finalizing score calculation

What to Monitor (if using HWiNFO64/Afterburner):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
GPU Temperature:
├─> Idle: 30-50°C
├─> Under Load: 65-85°C (normal)
├─> ⚠ Warning if >85°C (potential throttling)

GPU Clock Speed:
├─> Should reach advertised boost clock
├─> Example: RTX 3070 should hit ~1900-2000 MHz
├─> ⚠ If clocks dropping during test: thermal throttling

GPU Usage:
├─> Target: 95-100% (GPU fully utilized)
├─> If <90%: Possible CPU bottleneck or browser issue

GPU Power Draw:
├─> Should approach TDP rating
├─> Example: RTX 3070 TDP 220W should draw ~210-220W
├─> Lower power = possible throttling or power limit

Do NOT:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✗ Click away from browser tab (may pause test)
✗ Open other applications
✗ Stop test prematurely (invalidates results)
✗ Adjust fan speeds mid-test (affects thermal data)

├─> Check GPU-Z for correct PCIe lane usage (x16)
├─> DDU (Display Driver Uninstaller) + clean driver install
├─> Check for BIOS updates (motherboard)
└─> If persistent: possible hardware defect

If Thermal Throttling Detected (temps >85°C):
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
├─> Clean GPU cooler (compressed air)
├─> Increase fan speed (custom curve)
├─> Improve case airflow (add fans)
├─> Consider repasting GPU (advanced users)
└─> Retest after thermal improvements

If Interested in Overclocking:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
├─> Document stock performance first (done!)
├─> Research safe OC values for your GPU model
├─> Use MSI Afterburner for incremental testing
├─> Benchmark after each adjustment
└─> Target: 5-15% performance improvement

If Considering GPU Upgrade:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
├─> Use current score as baseline
├─> Research scores for target GPUs
├─> Calculate performance gain percentage
├─> Consider cost per performance point
└─> Ensure PSU/CPU can support new GPU

Advanced Testing Techniques

Step 13: Repeated Testing for Consistency

Statistical Validation Protocol:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Why Multiple Runs Matter:
├─> Single run can be affected by random factors
├─> Thermal state varies (cold start vs heat-soaked)
├─> Background processes may intermittently interfere
└─> Statistical average provides true performance picture

Recommended Protocol:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Run 1 (Cold Start):
├─> PC idle for 10+ minutes before test
├─> GPU at idle temps (~40-50°C)
└─> Often highest score (coldest temps)

Wait 5 minutes (allow GPU to cool slightly)

Run 2 (Warm):
├─> GPU starts warmer (~55-65°C)
└─> More representative of gaming session

Wait 5 minutes

Run 3 (Heat-Soaked):
├─> GPU and case warmed up
└─> Tests thermal throttling resistance

Continue for Runs 4-5...

Calculate Statistics:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Run 1: 8,520 points
Run 2: 8,485 points
Run 3: 8,440 points
Run 4: 8,505 points
Run 5: 8,465 points

Mean: 8,483 points
Standard Deviation: 31.8 points
Variance: 0.37% (excellent consistency)

If std dev >3%: Investigate inconsistency
Possible causes: Thermal throttling, background interference

Step 14: Stress Testing

Extended Stability Testing:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Purpose: Verify long-term stability and thermal performance

Method 1: Back-to-Back Benchmarks
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Run benchmark immediately after it completes
2. Repeat 5-10 times without breaks
3. Monitor each score and peak temperature

Example Results:
Run 1: 8,500 pts, 76°C peak
Run 2: 8,480 pts, 79°C peak
Run 3: 8,455 pts, 81°C peak
Run 4: 8,420 pts, 83°C peak ← Slight throttling
Run 5: 8,410 pts, 84°C peak
Run 6: 8,405 pts, 84°C peak ← Thermal equilibrium

Analysis: -95 points over 6 runs (-1.1%)
Conclusion: Minimal throttling, good thermal solution

If score drops >5%: Thermal throttling issue
Action: Improve cooling before regular use

Method 2: Monitoring During Stress
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Use HWiNFO64 logging:
1. Start HWiNFO64 logging before test
2. Run extended stress (multiple back-to-back tests)
3. Stop logging after final test
4. Review graphs for:
   ├─> Clock speed consistency (should stay high)
   ├─> Temperature trends (should plateau)
   ├─> Power draw stability (no drops)
   └─> Thermal throttling flags

Healthy Pattern:
├─> Temps rise quickly, plateau at 75-83°C
├─> Clocks maintain boost frequency
├─> Power draw consistent
└─> No throttling flags

Problem Pattern:
├─> Temps keep climbing past 85°C
├─> Clocks start dropping after 2-3 minutes
├─> Power draw decreases
└─> Throttling flags triggered

Troubleshooting Common Issues

Issue 1: Test Won't Start/Load

Symptom	Cause	Solution
Blank screen or "WebGL not supported" error	WebGL disabled in browser	Chrome: chrome://flags > Enable WebGL Firefox: about:config > webgl.disabled = false
Test starts then immediately crashes	Outdated graphics driver	Update GPU driver to latest version
Page loads but test button doesn't work	Browser extension interference	Disable extensions or try incognito/private mode
Very low FPS from start (<5 FPS)	Browser using integrated GPU instead of dedicated	Windows: Graphics Settings > Add browser > Set to High Performance

Issue 2: Score Much Lower Than Expected

Systematic Diagnosis for Low Scores:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Step 1: Verify correct GPU being used
├─> Open Task Manager during test
├─> Go to Performance tab > GPU
├─> Verify dedicated GPU shows 95-100% usage
└─> If integrated GPU active: Fix graphics settings

Step 2: Check for thermal throttling
├─> Monitor temps with HWiNFO64/GPU-Z
├─> If temps >85°C: thermal throttling occurring
├─> Solution: Improve cooling, clean GPU

Step 3: Driver verification
├─> Check driver version (should be <3 months old)
├─> Try DDU clean install of latest driver
├─> Retest after driver installation

Step 4: Background process check
├─> Open Task Manager > Processes
├─> Sort by CPU and GPU usage
├─> Close any apps using >5% CPU/GPU
├─> Retest with clean system

Step 5: Power settings
├─> Verify Windows on "High Performance" mode
├─> Check GPU power cables properly connected
├─> Monitor power draw (should hit TDP rating)

Step 6: Hardware verification
├─> Run GPU-Z, verify:
   ├─> PCIe slot: x16 (not x8 or x4)
   ├─> Bus Interface active: PCIe x16
   ├─> GPU running at rated clocks
└─> Reseat GPU in motherboard if issues detected

If all checks pass and score still low:
⚠ GPU may be defective or thermal paste degraded
→ Consider warranty claim or professional service
