help lowering Vcore on Q6700

post #1 of 5
Thread Starter 
I have my q6700 clocked to 360 @ 1.65v in the bios. idle temps are at 43c, Linx hits 95c, and Prime around 80c on small ffts.

The vid is 1.325 so I know 3.6 is not an easy clock on air.

Here are my settings.


Robust Graphics Booster___________ [Auto]
CPU Clock Ratio ____________ [10]
CPU Host Clock Control_ [Enabled]
CPU Host Frequency (MHz)__________ [360]
PCI Express Frequency (Mhz)_______ [100]
C.I.A. 2__________________________ [Disabled]
System Memory Multiplier (SPD)____ [2.00D]
DRAM Timing Selectable_______ SPD __ [Manual]

Performance Enhance = [Standard]

CAS Latency Time________________ 5
Dram RAS# to CAS# Delay_________ 5
Dram RAS# Precharge Delay_______5
Precharge Delay (tRAS)__________ 18
ACT to ACT Delay (tRRD)_________ Auto
Rank Write to READ Delay________ Auto
Write to Precharge Delay_________ Auto
Refresh to ACT Delay______________ Auto
Read to Precharge Delay__________ Auto
Static tRead Value_______________ Auto
Static tRead Phase Adjust________ Auto

CPU/PCIEX Clock Driving Control [800mV]
CPU Clock Skew Control [normal]
GMCH Clock Skew Control [Normal]

System Voltage Control____ [Manual]
DDR2 OverVoltage Control__ [+0.300V]
PCI-E OverVoltage Control_ [Normal]
FSB OverVoltage Control___ [Normal]
(G)MCH OverVoltage Control [Normal]
CPU Voltage Control_______ [1.65]


Can I lower my my Vcore by upping FSB and/or GMCH?

What is normal and safe levels for these (fsb/GMCH)?

Is my Vcore and Temps ok for stress testing but Good for 24/7?

Your temps are too high. It's not worth the extra 200MHz overclock for a shorter lifespan.
Lower your vCore
post #3 of 5
Yeah, you dont really want to go over 80C and generally, people say 1.55v is MAX. I personally like to stay under 1.5v.

What does CPU-Z report your actual vcore at? Im curious how much vdroop your Mobo has.

My Q6700 has a 1.26 VID and 3.7Ghz is my max under 1.49v or so. It wasn't worth the voltage and temps to try 3.75Ghz. Honestly, anything over 3.2Ghz is gravy. I can play any game I've tried at 3.2Ghz with a decent GPU. Mainly, BlackOps, BC2, Homefront, Crysis 2.

Have you enabled LLC (Load Line Calibration)? Try enabling that, then lower your clocks and volts and see if that helps to eliminate the vDroop.

Thanks for the help guys. I brought it down from 1.65 to 1.597 and running 3.48.

@ 1.65 i was getting brief peaks of 1.744 in CPUz but mostly about 1.68 under LinX stress testing.

Its strange. Below 1.6 I would see Vdroop. After 1.6 it would actually spike during load.

I wanted to use LLC but Ive read so many mixed discussions about it... some say its safe, others say its not, other say safe until 1.45... 3.48 and ram at 928 is good.
