- The following results can vary depending on the batch processor
- The following results are purely IBT test dive 10xloop, for short daily stable
In the first test session I decided to walk 4.5GHz for setting daily. To the memory of accidentally
reduce the clock to get Vdim with targat 1.5V, so the memory running 800MHz 8-8-8-24 1T 1.5V.
It should be noted on the mobo Asrock P67 Turbo bost Pro3 this should be set manually to avoid the occurrence of
processor clock throttling that sometimes the CPU multiplier down automatically when the heavy load
setting when auto / default
short duration power 118
longpower duration 95
current limit of 150 cores
In test 2, do raise I5 2500K to 46x multipier with Bclk 100. Memory is still the same 800MHz 8-8-8-24 1.5V IT.
This Diclock dibios fixed Vcore 1.32v which seems diHW monitor 1.31v, 1.312v CPUZ, looked down but still reasonable
temperature recorded with s-963 began to crawl up through 70C in the daytime, such as SS is quite successful.
To others still can Vdim 1.5V, VTT 1.207v.
On the 3rd test, overvoltage PLL enabled, the CPU need extra bursts of valtage disocket besides CPU PLL (Vpll)
via mobo. when overvoltage disable mostly stuck di4.7 OC-4.8GHz, so the bios update is required untukmemunculkan PLL option overvoltage, when the test was written using bios 1.7.
For road diclock 4.7GHz, memory at 800MHz 8-8-8-24 1T still Vdim 1.5V, VTT 1.259v, 1.35v Vcore 0.03v need of additional
previous setting 4.6GHz.
Final test to decide di4.8GHz daily at 1.38v Vcore dibios, consider the temperature and the batch processor for diVcore reportedly safe for daily 1:35-1.4v
As I walked di4.8GHz still di800MHZ 8-8-8-24 1T memory Vdim only 1.53v. but had tried Vdim 1.5V
IBT bluscreen arise when the memory dump, possible lack of memory voltage, VTT need 1.311v for IBT 10xloop success. Rose quite significantly from 4.7GHz 1.259v VTT,
had slightly raise the VTT 1.285v hangs / memory dump. For Turbo boost wattag
Vccsa same auto CPU PLL. Recorded temperature increases through 76C, is still tolerable daily made me think not that high, depending
application that is run and a better HSF would result even better.
VERDICT
Overclocking with Asrock mobo pro3 P67 is quite fun, there are auto profile OC, UEFI BIOS option that is easy to operate. In manual testing is to run> di4.7GHz need to update bios to unlock overvoltage PLL options, which can be external or dicari2 diforum ASRock website. When testing 1.7 bios OC already enough to reach up to> 5GHz with additional options dibios max Vcore 1.52v. ASRock P67 pro uses 8 +2 phase with different Extreme4 ASRock diheat sinks are still passive. Regarding the performance and Scaling OC will be discussed once by ASRock P67 Extreme4 which
under construction. yes just wait.
