Alright, I think that I've reached a stable configuration. I still have some testing to do, but the culprit of my previous instability issues was caused by the Memory. That Memory is giving me headaches.
Here are my settings:
Code:
Robust Graphic Booster ..................... [Auto]
CPU Clock Ratio ............................ [ 9 x]
CPU Frequency .............................. 3.70GHz (412x9) / Strap 2.40B (5:6)
CPU Host Clock Control ..................... Enabled
x CPU Host Frequency(MHz) .................. 412
PCI Express Frequency(MHz) ................. 100
C.I.A.2 .................................... [Disabled]
Performance Enhance ........................ [Standard]
System Memory Multiplier ................... [Auto]
Memory Frequency(MHz) ............. [800]
DRAM Timing Selectable (SPD) ... [Manual]
********** Standard Timing Control **********
CAS Latency Time ................. 5
DRAM RAS# to CAS# Delay .......... 6
DRAM RAS# Prechard ............... 6
Precharge Delay(tRAS) ............ 16
********** Advanced Timing Control **********
ACT to ACT Delay(tRRD) ........... 4
Rank Write To READ Delay ......... 4
Write To Precharge Delay ......... 8
Refresh To ACT Delay ............. 58
Read To Prechard Delay ........... 4
Static tRead Value ............... 8
Static tRead Phase Adjust ........ Auto
Command Rate(CMD) ................ 2
******* Clock Driving & Skew Control ********
CPU/PCIEX Clock Driving Control ............ 1000mV (what's that option for?)
CPU Clock Skew Control ..................... [Normal]
(G)MCH Clock Skew Control .................. [Normal]
********* System Voltage Optimized **********
System Voltage Control ..................... [Manual]
DDR2 OverVoltage Control ................... +0.35
PCI-E OverVoltage Control .................. [Normal]
FSB OverVoltage Control ..................... +0.20
(G)MCH OverVoltage Control ................. +0.175
MCH Reference Voltage Control .............. [Normal]
DDR Reference Voltage Control .............. 1.34375V (1.312V in CPU-z)
Normal CPU Vcore ........................... 1.22500V
So a 700Mhz over-clock, which isn't too shabby, I guess. But as I mentioned the Memory so far isn't very good and barely runs at default factory settings (seriously, I've experienced a few
BSOD's at 5-5-5-15 2.2V and 2.1V, but when I reduce the timings to 5-6-5-15 or 5-5-6-15 ot 5-6-6-15 or finally 5-6-6-16 then things seem to stabilize, so I've been using the 5-6-6-16 settings just to stay on the safer side. According to my benchmarks it didn't affect the performance much, if at all (from 8,480'ish ti 8,320'ish in Everest).
First I've tested the
CPU with Orthos (
CPU stress, no
RAM tested) for 6 hours without errors (I know I should go for more). Then I decided to test the Memory with a Blend test, and as I type this, with the settings shown above, it's been testing for 20 minutes without problems. I'll let it go for another six hours or so too, and then I think I'll stay there for quite some time. But right now I'm seriously considering to eventually change the Memory, and perhaps also the Power Supply, but I'd go with a Memory change first. I mean I've read almost everywhere on the web that my Memory is supposed to be able to run at 4-4-4-12 at 2.2V or 2.3V, but not only mine can't even
POST at anything below 5-5-5-15 at 2.2V, 2.4V and 2.4V, but it also isn't 100% stable at default settings, so they must be faulty... or maybe the
BIOS is just ruining everything... but I have yet to read any horror stories concerning that revision in particular.
