New i7-3770K Build with Sabertooth Z77 CPUZ Validation - Page 2

post #11 of 14
That's a lot of vcore for only 4.7. Most of the 2700k's I have tested (plus the two I own), only need around 1.30 for 4.7 (vares between chips though).

I think that about covers it. Any recommendations to get something stable without the vcore being so high?

My settings:
AI Overclock Tuner: Auto
Bclk: 100
Turbo Ratio: Manual
Ratio Synchronizing Control: Enabled
Ratio: 46
PLL: Enabled
DRAM ratio: Auto
Memory Frequency: 2133mhz
EPU Power saving: disabled
Ram timings: 9-10-10-30 2T
CPU Ratio: 46(same as above)
Speedstep: disabled
CPU Load-line calibration: extreme
CPU Voltage Frequency: Auto
CPU Power Phase Control: Extreme
CPU Power Duty Control: Extreme
CPU Current Capability: 140%
CPU Power Thermal Control: 130
CPU Power Response Control: Ultra Fast
Dram Current Capability: 100%
Dram Voltage Frequency: Auto
Dram Power Phase Control: Extreme
Dram Power Thermal Control: 110
CPU Voltage: 1.30v
DRAM Voltage: 1.615v
VCCSA Voltage: Auto (shows as 0.925v)
CPU PLL Voltage: 1.610v
PCH Voltage: Auto (Shows as 1.072v)
Other DRAM Settings set to auto (CHA/CTRl REF for CHA and CHB)
CPU Spread spectrum: disabled
BCLK recovery: Disabled

After setting CPU Power Response Control to Ultra Fast, I was able to lower PLL voltage to 1.61v without BSOD, and vCore temp dropped about 4 ~ 5'c, now at around 65 ~ 74'c max. Before it was hitting 81'c. I can't lower my vCore voltage anymore even by 0.05v it'd auto reboot after about an hour in P95. To get 4.7GHz stable on mine requires 1.4v and I have tried every combinations to no avail.

100'c is crazy!!!

Yea I know...even though 4.7GHz @ 1.4v barely raised my overal vCore temp by 1 ~ 2'c, I still wasn't comfortable with that much power into, so I backed down to 4.6GHz. Besides, I feel no difference at all lol.

I just downclocked to 4.4 and i'm getting much lower temps, especially with the PLL at 1.5v

Running it 4.4ghz on 1.16v, max temps in the 70-71C range.

Hello Everyone!
Im new to the forums... just built my comp earlier this month.
I haven't OC'ed the system yet but when i stuck everything in and turned on XMP then the system switched from 3.8 GHZ Turbo mode to 4.2 GHZ turbo.
Never touched anything else. My temps never go above 35C on extreme cooling mode on antec h20 920, how ever they to travel to 40 if i keep my Antec Khuler h20 920 on silent while under load (gaming) done hours of gaming with no problems.
So im thinking im pretty good on the setup right now.
Just had one question, will i get a big performance boost if i OC'ed to 4.7 ghz? I'm wondering how much of a temp jump i'll see if i'm under load with the cooler on extreme mode.

THX
