Sweet spot for CPU-NB seems to be 2400-2600 on FX chips.

 

Ok...going to try that with the NB @ 2400...my expectations are a no boot. We'll see! BRB!

 

As I suspected, no boot! Had to switch off the psu and turn it back on, and the motherboard told me my overclocking failed. Below are the settings in BIOS that I used...

^this 2200-2600 is the sweet spot
set NB voltage @ 1.3 (this helps stability)
chips also don't like high fsb clocking ..good to around 220-ish though
the RAM is a bit of a PITA...

good luck!

 

Wait which one, cpu-nb or nb voltage? Because cpu-nb is closer to 1.3 and cpu-nb by default is around ~1.090v, so it seems a bit of a jump

 

CPU-NB

Also, disable spread spectrum. It will royally ruin your OC ability.

The VRM spread spectrum was already off..the cpu one too?

 

This is too stomach churning for me. I don't wanna screw up my system...and I already get 45-60fps playing BF3 which is all I care! When I get a SB I'll do some real OC'ing...I'm gonna play it safe and not OC

EDIT: Yes, I tried the last things you guys said. I would get past BIOS menu but when going into windows it would say "Loading files" and it would reset...brought it back down to 3.6ghz and no such problem!

Sigh.. As I have already stated:

You may also want to raise the NB speed as well while raising the voltage as it can help for stability. Get it to at least 2400 - 2600MHz with the formentioned 1.3v for testing purposes and then you can tweak it up higher once you know your CPU speed is stable. Also manually set your RAM voltage AND timings to spec.
EDIT: Also change CPU Power Phase Control to Extreme & CPU Power Duty Control to whatever the other option is. (can't think of what it's called )

You are not going to be able to do higher clocks if you don't change that Power Phase Control for sure.

 

Mind you I didn't see that Edited part, lol. Thanks..I think I'll try it as well anyway.

I keep getting confused. WHICH voltage of the NB, the CPU-NB voltage or purely NB voltage?

 

Will clarify NB and CPU-NB.

NB is the PCI-e hub on the mainboard, CPU-NB is the memory controller in the cpu. I will need to look up your MB for the power phase settings tho.

My increasing the NB speed to 2400, I noticed that CPUZ was reading my pcie link width to x8, which is obviously wrong. I changed it back to auto and now it's reading it at the normal x16. And on top of that, I got a BSOD without even raising the clock. I did everything you said to do and I got a bsod that ended in 0x3D. I took off the 2400 and left it auto, and no BSOD.

Ok. Then don't raise the NB speed via multiplier. Leave the multiplier on auto and change it via FSB. Try for a combination of FSB + Multiplier which will yield you 4.2GHz & 2400MHz NB roughly. Make sure the NB speed is set to 1.3v.

THEN ALSO make sure those power phase options are changed or you won't get anywhere. AND make sure the RAM settings are manually entered as well as the timings.

Ok, I'll give that a shot. I changed the CPU Power Duty control to balance instead of thermal.

 

For 2400 you will need CPU-NB at ~1.3v

Also make sure you change the HTT speed back down to 2000 just in case.

Ok...I did the tinkering with the numbers to get 4.2ghz and 2400 vias the FSB...and no luck. Had to reset cmos. Don't ask me how, but the default bios reset now puts the fsb at 230. So I left everything at auto, except for the power stuff, and brought down my RAM to what would normallly be 1066 but with the 230 fsb to about 12xx...here's a print screen of cpuz

 

Well I tried and it just wouldnt let me boot. Had to reset cmos.

 

And of course this right now is not stable. Got an error on prime95 within 2 minutes. #YAY...NOT

 

metinks 230 is a tad too high for fsb..i saw bsods with that chip i've never seen before or since :

: umm..getting the RAM right is a pain,too..try increasing trFC..

trFC?

 

it's in the RAM timings section..."row refresh cycle time" if it doesn't say trFC

 

Well, I got it there. Unfortunately, that voltage is WAY too high and I don't have enough cooling :/ I'm gonna have to suffice with stock speeds for now.

 

i was gonna buy the 4100 but after seeing how you did with this,, im gonna keep my PII X4 im running it 3.9 daily and have pushed it to 4.0 .
