TESTING 12700KF / Thermalright Frame / 51p/40e / 3840x1600
0Necessary Intro Essay lol:
Detailed performance data is visible throughout the video capture; the vid capture is best viewed at full screen with 4K option selected as OSD typeface is rather small. The capture was made playing at 3840x1600 on an AW3821DW Ultrawide Monitor (roughly ~20% less pixel count than full 4K).
I'm using Dying Light 2 here to briefly check performance data with my ongoing overclock tuning of a new 12700KF build and specifically after installing a Thermalright frame in place of the stock ILM CPU locking mechanism.
In game settings are mostly maxed while using a DLSS setting of "Balanced"; using a DLSS setting of "Quality" results in about a ~5fps to ~10fps drop on average. The in-game quality settings are briefly shown at the start of the video and detailed OSD data is visible throughout.
You can find a link to a detailed review of my results using the Thermalright frame versus the stock ILM bracket at the bottom of the following nonsense...
TEST SETUP:
Room Ambient: 23C
Case: Corsair 780T full tower case all fans at 50%
MB: Asus Z-690-E Strix Gaming motherboard
CPU: 12700KF @ 51p/40e / Thermalright Correction Frame
GPU: EVGA 3080 Ti XC3 Ultra Gaming GPU (stock w/ fan curve at 45% to 87% swing)
CPU Cooler: H115i XT Pro - PUSH/PULL - top intake - all fans 50%
TIM: Noctua NT-H2
RAM: Corsair DomPlat DDR5 6000 CL36 1.25v @ 6400mhz CL36 1.35v
RAM Cooling: single 140mm fan mounted over DIMMs
CPU BIOS SETTINGS
Core ratios: "Sync all cores"
PCORE ratio: "51" (5.1ghz)
ECORE ratio: "40" (4.0 ghz)
All CPU Voltages bios settings: "AUTO"
Auto Voltage Cap bios setting: "1.35v"
Load Line Calibration (LLC): "5"
MEMORY BIOS SETTINGS
DDR5 STOCK: 6000mhz / 36-38-38-76 / 1.25v
DDR5 OVERCLOCK: 6400mhz / 36-38-38-76 / 1.35v
And that's all I did in-bios for this tentative 51p/40e 12700KF test. FWIW? I left the Windows 11 power settings on the "High Power" profile so the core speeds stayed static at all times (same as oldschool 8th gen "AVX offset: 0" basically.
As the OSD data shows, with LLC 5 and Auto Voltage Cap at 1.35v? The VCORE will swing up towards 1.39v on rare occasions while remaining generally around ~1.365v on average. This is/was exactly what I was expecting. LLC 4 did not allow enough upswing past the voltage cap set in bios for CBr23/general gaming stability but LLC 5 works fine (so far).
But the main goal was to ensure all P cores stayed pegged at 5.1ghz and all E Cores stayed pegged at 4.0ghz. And the voltage management turned out to be exactly what I was expecting with using the above OC method and management of core voltages.
But still ... even with this odd, simple but effective OC method? Everything runs pretty solid and chilly at 51p/40e thus far.
