Hi guys,
I have recently plugged together two PCs for general domestic use and would appreciate you guys double-checking my BIOS settings. My previous experience includes lashing together lower-end AMD PCs from a mixture of new and scrap parts. These are my first Intel-based PCs using all new parts, and as these builds mean expenditure is actually double the cost of the components mentioned, I must confess to experiencing a little uneasiness at my relative inexperience with modern-day set-ups.
I have viewed, accepted, and adopted Tom Logan's advice given in his Intel 1155 Overclocking Guide video at:
Components:
Intel Core i7-4770K Processor
Gigabyte Z87X-UD3H Motherboard
Corsair 16GB (2x8GB) 2133 DDR3 Vengeance Pro DRAM
Corsair CX750M Modular ATX Power Supply
Corsair Obsidian Series 550D Quiet Case
At this stage future upgrade suggestions, whilst more than welcome, are of little consequence as my total budget, and more, has already been spent. This means while I would love to purchase a couple of XSPC watercooling kits, and remember every purchase is times two, here and now and into the foreseeable future I must use the Intel OEM supplied fan. This fan, CPU integrated graphics being new to me, and an auto turbo CPU frequency setting, were the initial causes for my insecurity in trusting the auto default settings within the BIOS.
Notes: Bought for fun as last purchases of modular contructed PCs before individual components are replaced with miniaturised NUCs. Hoping for six years use. Not interested in overclocking. After years of noisy PCs my current ambition is quietness in use. HDD and SSD located in 5.1/4" drive bays. Both HDD brackets removed for increased airflow from 2 x 120mm front panel fans.
BIOS SETTINGS (Classic Setup)
Whilst viewing Tom Logan's video I wrote down eight tasks:
1. BIOS > F7 Optomised Defaults > Reboot
2. MIT \ Advanced Frequency Settings \ Advanced CPU Core Features
CPU Clock Ratio: 35
CPU Frequency: 3.5GHz
Uncore Ratio: 35
Uncore Frequency: 3.5GHz
Intel Turbo Boost Technology: Enabled
Turbo Ratio (1-Core Active) (39): Auto
Turbo Ratio (2-Core Active) (39): Auto
Turbo Ratio (3-Core Active) (38): Auto
Turbo Ratio (4-Core Active) (37): Auto
Everything Else: Auto
3. MIT \ Advanced Memory Settings
Memory Upgrade: Disabled
Extreme Memory Profile (XMP): Disabled
System Memory Multiplier: 18.66
Memory Frequency: 1866MHz
Performance Enhance: Normal
DRAM Timing Selectable: Quick
Notes: Accepted and adopted Tom Logan's statement concerning overstressing the CPU memory controller during stress testing. Memory frequency still set at 1866MHz after OCCT stress test.
4. MIT \ Advanced Memory Settings \ Channel A Timing Settings
Channel A Standard Timing Control
CAS Latency: 11
tRCD: 11
tRP: 11
tRAS: 27
Channel A Advanced Timing Control
Command Rate (tCMD): 2
Notes: Clocking set to Corsair tested clocks, whilst Corsair tested memory frequency of 2133MHz reduced to 1866MHz.
5. MIT \ Advanced Voltage Settings \ 3D Power Control
CPU VRIN Loadline Calibration: Extreme
Everything Else: Auto
Notes: Hesitated at this point as was expecting to see Vcore Loadline Calibration option. Changed VRIN to Extreme anyway.
6. MIT \ Advanced Voltage Settings \ DRAM Voltage Control
DRAM Voltage: 1.500V
7. MIT \ Advanced Voltage Settings \ CPU Core Voltage Control
CPU VRIN External Override (1.800V): Auto
CPU Vcore (1.170V): 1.000V
Everything Else: Auto
8. F10 Save & Exit
TESTING
OCCT 4.4.0
CPU:LINPACK tab
Memory: 90%
64 Bits check box ticked
AVX Capable Linpack check box ticked
Use All Logical Cores check box ticked
Monitoring Options
Cores #0, #1, #2, and #3
Stop testing if value is above: 90°C
Test 1
10 minute test failed at 3 minutes.
Action: Back into BIOS and set Intel Turbo Boost Technology option to Disabled.
Test 2
10 minute test Passed.
Core #0: 34-83°C
Core #1: 32-83°C
Core #2: 31-81°C
Core #3: 33-80°C
Action: Back into BIOS and set Intel Turbo Boost Technology option to Enabled. Set all Turbo Ratios (1, 2, 3, and 4-Core Active) to 37.
Test 3
10 minute test Passed.
Core #0: 36-85°C
Core #1: 34-86°C
Core #2: 32-84°C
Core #3: 33-82°C
Action: Back into BIOS and set all Turbo Ratios (1, 2, 3, and 4-Core Active) to 38.
Test 4
10 minute test Passed.
Core #0: 35-87°C
Core #1: 35-88°C
Core #2: 33-85°C
Core #3: 34-85°C
Test 5
Re-run OCCT stress test for 1 hour with above BIOS settings.
Passed.
CONCLUSION
Happy with CPU core voltage of 1V. Happy with CPU core temperatures never reaching 90°C under OCCT maximised stress test. Happy with x38 turbo multiplier. Happy with turbo ratio (1-core active) reduced from 39 to 38. Happy with turbo ratio (2-core active) reduced from 39 to 38. Happy with turbo ratio (3-core active) remaining the same at 38. Happy with turbo ratio (4-core active) increased from 37 to 38. Happy with 3.8GHz (8.3%) CPU overclock. Happy with memory frequency at 1866MHz. Oh so paranoid I am about to damage or destroy components!
Best regards,
John.
