Need help lowering voltage on stable O.C. of a 930 @ 4.0 on ga-x58a-ud3r

below are my settings for a tested 24hr prime95 blend run:

BCLK         191
PCI EXPRESS FREQUENCY      100
CPU CLOCK DRIVE      800mV
PCI EXPRESS CLOCK DRIV      900mV
CPU CLOCK SKEW      0ps
IOH CLOCK SKEW      0ps
PERFORMANCE ENHANCE      STANDARD
EXTREME MEMORY PROFILE   DISABLED
SYSTEM MEMORY MULTIPLIER   8.0
DRAM TIMING SELECTABLE   AUTO
INTEL TURBO BOOST      DISABLED
CPU MULTI-THREADING      ENABLED <-- i want to leave it enabled
C1E         DISABLED
C3/C6/C7         DISABLED
CPU EIST FUNCTION      DISABLED
BI-DIRECTIONAL PROCHOT   ENABLED

ICH I/O         AUTO --> SHOWS 1.500V IN BIOS
ICH CORE         1.200V <-- SET IN BIOS
DRAM VOLTAGE      1.640V <-- SET IN BIOS

my chip is a i7-930 [3001a125]

room temp is 79f <-- max summer temp in house

in a 20min run with prime95 blend my max core temp is 80c using an h50 with 133 cfm fan in pull mode. i am wanting to lower my vcore to help reduce my temp and i was wondering what other voltage adjustments i could make to help reduce the vcore. any sugestions would be much appreciated. o yea if you use my settings and melt your machine it is not my fault

i think there are some voltages i can increase which will allow me to decrease the vcore. since i am still a noob at this i am not sure which ones to increase.

Real world usage will possibly never stress the cpu as much as prime95, so really you would be looking at temperatures of 60-70C maximum uunder normal usage.

As for the voltages, try reducing the CPU Vcore one notch at a time until it becomes unstable again, it is a long process but you don't want your overclock to fail. Run Prime95 each time you reduce it for a good few hours at least. I would guess you can reduce the Vcore to around 1.3V under load (CPU-z) - never use BIOS for the actual reading, download CPU-z. It is free to use and can be useful for this. I wouldn't hope for any temperature under 70C without using water at 4Ghz, as it is quite unlikely.

yea under normal gaming i hit mid 60's and i have not done any video encoding yet. when i get to do some vidoe encoding and if my temp's stay round 60's to 70's then i might just call it a day. prior to setting my vcore to 1.375 in bios i ran it two notches below that and it failed. i will try one notch below 1.375 and stress. i did a quick check (2 min) with prime to see my voltage in cpu-z one notch down and it was running about 1.294. i hope to do a real stress test this weekend it really check it.
