I've read everything I could find and tried everything I could think of trying to OC my E8400 over 400Mhz FSB and nothing seems to help.
Asus P5Q Pro
Intel E8400 EO stepping
Xigmatek HDT S1284 heatsink
Coolermaster HAF 930 case
G.Skill PC8000 2x2gb
Corsair 650TX 650w PSU
CPU temp never exceeded 40c to TJmax according to coretemp (60c reported temp).
This is my current bios settings for 3.6Ghz (9x400)
CPU Ratio 9
FSB 400
PCIe 101 (tried 100 and auto, no difference but 101 is the popular ideal setting)
FSB Strap 266Mhz
Dram Freq 1003Mhz
Dram Timing ~ Transation Booster Auto
CPU voltage 1.225 (1.208 idle/orthos load)
CPU GTL ref auto
CPU PLL 1.52
FSB Termination 1.52
DRam 2.1v (Rams rated voltage)
NB Voltage 1.12
SB Voltage auto
PCIe/SATA auto
Load-Line Enabled
CPU/NB Spread spectrum disabled
CPU/NB Clock Skew enabled
C1E, Max CPUID, Virtualization tech, TM Function and Execute disable bit are disabled.
I ran orthos for 96 hours without any errors (work long hours so wasn't using the pc anyway lol) and have no signs of any instability.
After spending several hours messing with settings I gave up at these settings. Note: No difference in stability from 410Mhz to 445Mhz FSB with these settings. Orthos errors within 60 seconds in Blend and 2-3 minutes small FFL.
CPU Ratio 9
FSB 445
PCIe 101 (tried 100 and auto, no difference but 101 is the popular ideal setting)
FSB Strap 333Mhz
Dram Freq 1003Mhz
Dram Timing ~ Transation Booster Auto
CPU voltage 1.4 (1.386 idle/1.388 orthos load)
CPU GTL ref auto
CPU PLL 1.60
FSB Termination 1.30
DRam 2.1v (Rams rated voltage)
NB Voltage 1.38
SB Voltage auto
PCIe/SATA auto
Load-Line Enabled
CPU/NB Spread spectrum disabled
CPU/NB Clock Skew enabled
I didn't just jump up to 445Mhz or those voltage settings, thats just where I stopped before I went nuts. Nothing I did seemed to do anything for stability, even setting the CPU multiplier to 6 and ram to under 900Mhz to be positive I wasn't running into problems there.
I updated my Bios from the stock 1103 to 1406m (ket's) with no change.
I think the only thing I've accomplished is knocking a couple years off my CPU and mobo's lifespan
Sorry if this post isn't very organized, just got off a 10 hour shift at work after only 3 hours sleep so i'm just trying to be accurate lol. I just know I'll forget something important but I need to get to bed. I've just about givin up and accepted either the cpu or mobo simply can't exceed 400mhz fsb heh.
P.S. I'm a bit of a newb with modern overclocking, last OC'ing I did was with a 1.6Ghz Applebred Duron and an Abit NFS-S mobo (sucker practically overclocked it's self, you were just along for the ride and start benchmarks ) so don't be afraid to suggest something newbish hehe.
