I was able to achieve a stable (20 min of LinX) overclock with a BCLK of 148 (any higher and I'll get to where the voltages will require new cooling solutions, which will probably result in eventual watercooling lol) and a Clock Ratio of 25X. These are the following stats, using Slaymate's template:
Bios Template
•Mother Board (Gigabyte GA-X58A-UD9)
•Drivers (all current)
•Bios (5fg )
•CPU (i7-980X)
•CPU Cooler (stock)
•Memory ( G.Skill Trident+ Turbulence II 12GB (3 x 4GB) DDR3 2000)
•PSU (Silverstone ST1500 1500W)
•GPU (2 x XFX ATI Radeon HD 5970 2 GB)
•Drivers (Catalyst 10.11--drivers only)
•Operating System (Windows 7 64-bit)
Frequency Control
•CPU Clock Ratio (25X)
•CPU Host Frequency/BCLK (148)
•MCH Strap (???)
•CPU Uncore Frequency (2960 MHz {X20})
•CPU Clock Skew (0 ps)
•Spread Spectrum (???)
•PCIE Frequency (Auto)
•OC Recovery (???)
Here are some Frequency settings that weren't mentioned, as I couldn't find all of the ones requested:
QPI Clock Ratio (Auto)
QPI Link Speed (5.32 GHz)
Extreme Memory Profile (Disabled)
PCI Express Clock Drive (900 mV)
CPU Clock Drive (800mV)
IOH Clock Skew (0 ps)
Memory Feature
•Memory Speed (10X)
•Memory Control Setting (???)
•Memory Frequency (1480)
•Channel Interleave Setting (Auto)
•Rank Interleave Setting (Auto)
•Memory Low Gap (???)
•tCL Setting (8)
•tRCD Setting (8)
•tRP Setting (8)
•tRAS Setting (24)
•tRFC Setting (72)
•Command Rate (2)
Some Memory settings that weren't mentioned:
Performance Enhance (Expert)
DRAM Timing Selectable (Auto)
Voltage Control
•Load Line Calibration (Enabled, Level 1)
•CPU VCore (1.275V)
•CPU VTT/QPI DRAM Voltage (1.175V)
•CPU PLL VCore (1.800V)
•DIMM Voltage (1.640V)
•DIMM DQ Vref (???)
•QPI PLL VCore (1.140V)
•IOH VCore (1.100V)
•IOH/ICH I/O Voltage (1.500V)
•ICH VCore (1.100V )
•PWM Frequency (???)
There was one Voltage setting that wasn't mentioned:
PCIE (1.500V)
CPU Feature
•Intel SpeedStep (Disabled)
•Turbo Mode Function (Auto)
•CxE Function (???)
•Execute Disable Bit (Enabled)
•Virtualization Technology (Disabled)
•Intel HT Technology (Enabled)
•Active Processor Cores (All)
•QPI Control Settings (???)
•QPI Link Fast Mode (???)
•QPI Frequency Selection (???)
Here are some that weren't mentioned:
CPU Enhanced Halt--Disabled
C3/C5/C7 State Support--Disabled
CPU Thermal Monitor--Enabled
Bi-Directional PROCHOT--Enabled
So, having established my max BCLK, I thought I'd mess around with getting my memory up to its max frequency of 2000. With that in mind, I changed the above settings to the following:
BCLK (143)
MULTIPLIER (26X)
CPU FREQUENCY (3.71)
MEMORY MULTIPLIER (14X)
MEMORY FREQUENCY (2002)
UNCORE MULTIPLIER (28X)
UNCORE FREQUENCY (4004)
QPI LINK SPEED (6.86--AUTO)
MEMORY LATENCIES (9-9-9-24-74-2)
The results... infinite reboots with no POST. I had to reset my BIOS (not as bad as it sounds, as my motherboard has eight save slots for the BIOS settings, which is awesome AS LONG AS you enable the option to write these to your hard drive... if this isn't enabled, you lose everything, which I found out the hard way during a BIOS flash... lesson learned). I then tried knocking down the memory/uncore multipliers to 12X/24X. Same result. I then tried using the Extreme Memory Profile, which put the CPU Frequency in the neighborhood of 3.45 or so (didn't write it down, unfortunately), and the memory at 2002. Same result.
Basically, it seems like I cannot push my memory in any way other than by raising the BLCK... any other stuff results in no POST.
Any ideas? I should have much more headroom than what I'm getting.
PS--Slaymate, I know you recommended me boosting some voltages for more stable dual-GPU overclocking; I haven't forgotten this, I just want to do things one step at a time, so I'll boost those once I start applying a GPU overclock.
