Question Optimized Overclock for my Build? Suggestions? Please?


Sep 18, 2013
Attempting to get a performance boost past stock. So I am looking for someone to give me a their best guess on the highest OC Settings I can go without risking stability issues. I'm having issues at stock settings in games and don't believe my system specs (Although relatively old) should have as many performance issues that I have. My hardware specifications are listed below:

Computer Specifications:
  • Case: Deepcool Pangu v2
  • Motherboard: Asus Z87-PRO
  • CPU: Intel Core i5 4690K
  • CPU Cooler: Corsair H55
  • GPU: GIGABYTE GTX 980 WindForce 3X OC ( GV-N980WF3OC-4GD )
  • RAM: 4x2 Ballistix Sport XT DDR3 1866 ( BLS4G3D18ADS3 )
  • PSU: Antec HCG-620M
  • HDD: Seagate ST10000DM003-1ER162
  • Monitor: Acer XFA240
  • Keyboard: Razer DeathStalker Essential
  • Mouse: Logitech G602
  • Headset: Logitech G430
Current BIOS Settings for Hardware:

  • CPU Core Voltage: Set to 1.25v
  • CPU Core Multiplier: x45.0 Synced across all cores
  • CPU Core Speed: 4498.95 MHz
  • CPU Cache Multiplier: x41.0 (Both Max and Min)
  • CPU Cache Speed: 4099.04 MHz
  • CPU Input Voltage: 1.9v

  • EIST: Disabled
  • Turbo Mode: Enabled
  • CPU Integrated Fault Management: Disabled
  • CPU Integrated VR Efficiency Management: High Performance
  • Power Decay Mode: Disabled
  • ASUS MultiCore Enhancement: Auto
  • Internal PLL Overvoltage: Enabled
  • BCLK Frequency : DRAM Frequency Ratio: Set to Auto
  • OC Tuner: As Is

  • DRAM Power Phase Control: Extreme
  • CAS# Latency: 10.0
  • RAS# to CAS#: 10
  • RAS# Precharge: 10
  • tRAS: 30
  • tRC: 45
  • Command Rate: 2
  • GPU VDDC: 1.2 (Under Load) 0.85 (Idle) (Stock)
  • GPU Clock: 1308 MHz
  • GPU Boost clock: 1409 MHz
  • GPU Memory: 1923 MHz
  • Power Limit Minimum: 37.0%
  • Power Limit Maximum: 111.1%

Please let me know if you see any issues with my current settings, I have tinkered around with it but found these settings to be stable for me. If anyone has any input on what I can optimize for maximum performance out of my build I would greatly appreciate it! Feel free to ask for any clarification on settings or hardware I have and I will do my best to provide it.

Just for somewhere to start- your mobo is better and you've a water cooler- I've an i5-4690K on an ASUS B86M-G mobo OC'ed to anywhere up to 4.5GHz with stock cooler below 1.25V, for stability and temps I'm closing in on 4.4GHz- still work in progress. I began with the ASUS auto recommendation, which started me @ 4.3GHz with a lot of auto settings, then tweaked CPU Core Voltage manually from the ASUS-provided Auto value some from there.

If you're looking for a guide on how to proceed, here's one (with stats on what #s others have got), there are many others. Or video, didn't see this 1st time since not my mobo but looks good for yours. There's also the ASUS RoG site/forum for info.
