It's not a bad thing. It's not going to do any damage. What is the value for VCORE when under load? Try check the actual CPU frequency using Real Temp, Open Hardware Monitor and/or CPU-Z. Make sure you didn't set "Minimum processor state" to 100% in "Power Options" (Control Panel).

5 years + is a good guesstimate So don't be afraid to voltup if you have to wink.gif
I think I suggested that to you already........ and do you like my Pineapple laughingsmiley.gif

Thanks man HOMECINEMA-PC.

You will just need to find the offset voltage that will supply the CPU with enough power to reach your desired overclock (I use +.0700 for instance, and this will translate into about 1.368 under stress testing). You can only use it on the 100 strap, but at 4.3 that should not be an issue. Enable Speedstep, and the C states, and your voltage will drop with your clocks. So to get it to work, your need to follow these rules:
- Bclk strap of 100 (you can adjust the Bclk If you want to clock higher than 4.3Ghz. I run at 105 x 43 = 4515).
- Use the Offset Vcore. Manual Vcore will override any power saving features.
- Enable "C" states and Speedstep.
Good Luck
cheers.gif

Dear Mr. Rmerwede, I understood your comments but I couldn't apply them in the bios. Here are the pictures of my bios settings:

(C states are enabled and SpeedStep is enabled too)





The VCORE is in YELLOW, it is 1.280volts.

Before when I was testing the OC stability with Prime95 it would spike to 4.3Ghz(or did cpu rendering etc. anything cpu intensive) then if I turned off Prime it would drop to a 1.2Ghz frequency if I wasn't running anything. My temps are Core1-4: 34-27-34-27C. And I can't really tell if they're higher now then when my frequency would actually display properly that it dropped. It's doing the same thing on CPUZ and CoreTemp.
*Just set everything to default clocks (3.6 Turbo @ 3.8) and it is doing the same thing. Everything is default/reset on motherboard. Will display at 3.7 or 3.8 constantly.
Cpu load is like 0-1% running core temp and everything in the background so I know nothing is running. Checked thoroughly. And CPU gadget is showing the same 0-1% usage.
Is this a bad thing? Is it always running 4.3 now? Can I fix it? How did I mess it up in the first place? PLEASE HELP redface.gif Thanks!

Coretemp reads the multiplier and FSB and states the maximum frequency, it doesn't change as the frequency changes. If CPUZ is reporting the same information however, it could be your that your C-States got disabled somehow. Run HWinfo or OpenHardwareMonitor for a bit of idle / stress and see if the min/max are changing. Will at least confirm if you have an issue or not, but coretemp always displays my max speed with the settings.

THANK YOU BOTH! biggrin.gif Love OCN. I downloaded OpenHardwareMonitor to check and the clock was set at 4.3Ghz constantly as well as CPUZ and Coretemp. Then I checked my power settings and I had it form "Balanced" to "High Performance" The second I changed it back it dropped back to 1.2Ghz idle like it usually did and the Voltage's, Temps, and everything lowered to the standard I had seen when I first monitored the baseline before OC'ing. thumb.gif

Im running 4.75ghz daily 24/7 since may. 4.625 before that. I use a h100 and 16gb of ram at 2000mhz.
post #1957 of 6501
It is my understanding that if you are overclocking your BCLK as well as cpu multiplier, Speedstep, C-States and Offset voltage will pretty much be useless. BCLK overclocking in conjunction with multiplier will get you the best "real world" and benchmark performance.

Changing the BCLK raises the FSB and increases system performance. Ive confirmed this by overclocking to 4.3 @ 100x43, benchmarking and overclocking the same but 125x34 = 4.25ghz

Speed Step is for multiplier and voltage drop to lower power consumption and heat. C-States are for core parking (individual core shut down). Ive also confirmed this with stock speed settings, diabling C-States but leaving Speedstep on still lowers voltage and power at idle.

What I'm basically saying is that if you are increasing system performance by raising BCLK, offset voltage + speedstep/c-states can be ignored completely. This also means that offset voltage can be ignored and manual voltage can be used?


Is is a correct interpretation?

offset or manual vcore?
speed step?
c-states?

what is voltage at full load?



Also are you stable in prime95 overnight?
Are you stable in IBT?
Are you stable in FurMark _AND_ Prime95 for longer than 30 minutes ?

Well... its happened....




BSOD up the bum (after doing all my benchmarks) All 0x0000101 bsod, no vcore will save it. Revert to optimized settings in bios, stock 3.6ghz. BSOD 101 and 1E. Up vcore. EVEN STOCK.

minidump file refers to ntoskrnl.exe dying some kind of death. Bsod'd just now sitting in windows. Set offset voltage to +.1 giving me 1.136v @ 1200mhz speed step and 1.36v at load. SEEMS stabled, going to try prime @ stock speeds


CPU frield ? Never went past 1.5v loaded, never hit more than 84degrees.

Boned?

HomeCinema - you were mentioning that your friend overvolted his cpu and now it doesnt take extreme LLC anymore? Could I have done this and that why even at stock auto voltages she isnt stable? It seems Ive stablized at 4.375mhz @ 1.5v (in cpuz) Im going to try higher, but I never needed this much vcore @ this speed before.

Seems im running a tad hotter in prime95 now as well. She did bsod overnight and was stock at the bsod screen instead of doing a reboot... could that have fried it?


Just doubled checked.. I hit 86 degrees just now priming for about 10 minutes, Ive not seen that temp before... somethings not right.
