Help with E8400 on P5K Overclock

[imported_Champ]

1. Overview of the problem
   Basically I'm psyched to try to get my system to 4.0GHZ after I saw several people doing that with an E8400 at around 1.3vcore. What I have found is that I cannot keep it stable at 3.6, I have about 30 seconds at 3.8 and instant blue screen at 4.0 (Testing for FSB walls so I tried several different clock speeds) well I'm giving up random trying and asking for your help.
   
2. Full description of the problem and symptoms
   
   I've set the Vcore at 1.36 and for some time it was relatively stable at 3.7GHZ, then I started getting random lockups and blue screens, I reset to stock and it became stable again. Now I want to try again to hit 4.0.
   
   Now I have done 24hours of memtest 86 with my ram so I'm fairly positive it is in working condition, (on another computer though if that makes a difference) although my sets are mismatched (both are Ballistics PC2-8500 just they have different heat spreaders and one set is rated at 2.0V and the other is rated at 2.2V, to be safe I run it at 2.2V, as well one sub timing is different but I run it at the slower one)
   
   Basically I would like to know anyone else settings with a similar set up, I'm on bios 1006 and here are the settings I used to be semi-stable at 3.7, although I can no longer duplicate that. Semi Stable meant about 4 hours of Orthos Stable and I used this setting for over a month without issue.
   
   Basically Now I cannot have anything stable, when entering at 3.6 it either bluescreens or completely locks up, at 3.8 it will get to the log in page then bluescreen, and at 4.0 it will not show the loading bar for windows. I have good cooling (8 fans and Freezer Pro 7) I just want to move to the next step everyone seems to be on.
   
   BIOS 1006 Settings
   

   Ai Overclock Tuner - Manual
   CPU Ratio Setting - Auto
   FSB Strap to Northbridge - Auto - can be set at 200, 266, 333, 400mhz
   FSB Freq - 410 - hoping to get to 450mhz
   PCIE Freq - 100
   DRAM Freq - 823 - keeping at 1:1
   DRAM timings 5-5-5-15 the rest AUTO
   DRAM Static Read Control - Disable
   Transaction Booster - Auto - can be set to ENABLED then 0-3
   CPU Vcore - 3.500
   CPU PLL Voltage - 1.50v - Can be set to AUTO or 1.70v
   FSB Term Voltage - 1.3v - Can be set to AUTO or 1.4v
   DRAM Voltage - 2.2v
   NB Voltage - 1.55v - Can be set to AUTO or 1.40v or 1.7v
   Clock Overcharging Voltage - AUTO - Can be set to 0.8v or 0.9v or 1.0v
   Load-Line Calibration - ENABLED
   CPU GTL Voltage Refernce - AUTO - Can be set to 0.63x or 0.61x or 0.59x or 0.57x
   NorthBridge GTL Voltage Reference - AUTO - Can be set to 0.67x or 0.61x
   CPU SpreadSpectrum - DISABLE
   PCIE SpreadSpectrum - DISABLE
   
   CPU Ratio Set - AUTO
   CIE Support - Disabled
   CPUTM Function - ENABLED
   Vanderpool Technology - DISABLED
   Executive Disable Bit - Disabled
   MaxCPUID Valve - Disabled
   Speedstep - Disabled

   
   The first setting is what I had it on and the others are what it can be, I`m not sure what everything means and I went by a random guide I found on the internet. If you can tell me what needs to be adjusted or what I need to do to make this happen it would be helpful
   
   Only changes made during semi stable overclock were installing Ubuntu.
   
3. My software:
   • 
     Vista Home Premium 64Bit
     Windows Firewall
     AVG Free 7.5
     SpyBot
     Using Everest for checking computer
     Ubuntu 32Bit
     None
     
   • My hardware
     • 
       HD 1 WD Raptor Vista Home Premium 64bit
       HD 2 Seagate 7200 250GB Ubuntu 32Bit
       E8400 - Artic Freezer Pro 7
       ASUS P5K
       8800GTS 640 - HR-03 Plus
       4x1 Ballistix PC2-8500
       Enermax Noise Taker II 600w
       Armor Case - Lots of fans
       
       Mods - not sure if this belonged in CPUs and Overclocking or Computer Help, so I just guessed, move if in wrong area

I think that's your problem right there. Just cuz the next guy can doesn't mean you can even if you both got the identical (no such things in computing) parts. Every cpu isn't made equal.

Ram has a lot to do with it also as by filling up all 4 banks puts stress on the NB. It is great to have your sights set high, but as for getting there can be a bit more complicated. Also getting to 4.0g on air with be a feat in itself. "Aigomoria" should be on this one for his input.

Remove two of your sticks of RAM, and your problems overclocking will magically go away. BTW, run HCI Memtest at stock speed; you may very well have a bad stick of RAM. Memtest86 is utterly worthless.

All processors are not created equal. You can't assume that you'll be able to hit 4.0 GHz on 1.3 vcore just because you've seen others do it.

It took almost 1.42 vcore (1.39 after vdroop) to get my Wolfdale relatively stable at 4.0, even with 2 sticks of RAM. I backed off to 3.82 @ 1.36 vcore (1.328 after vdroop) - it just wasn't worth the extra ~.6 vcore and 10 degrees Celsius for another 200MHz.

ok I pop out one set and give it a try

EDIT: So I have been able to hit 3.9 at 1.34v and nothing higher, so I have decided tweak it as much as possible to get it running the way I want, picked up dominators 2x2GB and running that at 1078mhz 5-5-3-13 at 2.1v and working on getting a higher freq, I'm sure my chip can do 4.0 on a better motherboard but I don't feel like buying a new one so call it a victory at 3.9
