Can I get some help reaching max OC? I'm using an ASUS P8P67 Pro board B3 Stepping with Bios 1305 or whatever the B3 boards came with.
VCCSA Voltage: 0.92500v
VCCIO Voltage: 1.00000v
CPU PLL Voltage: 1.75000v
Auto PLL Overvoltage: Enabled
PCH Voltage: 1.10v
VRM Frequency: 350
Duty Control: Extreme
Phase Control: Extreme
Digi + VRM Load Line Calibration: Extreme
Digi + VRM Current Capability: 130%
CPU Multi 45/46/47
CPU BCLK: 104.6/102.1/100
CPU voltage: for the 46 and 47 multi 1.425v in bios 1.44v idle, and 1.448v under load. For the 45x multi 1.47v in bios and 1.49v under load
DDR Voltage: 1.5v (Stock 1600 MHZ 9-9-9-24-2T Timings and Speed are rated at 1.65v)
DDR Speed: Auto Spread Spectrum: Enabled for 45x multi, disabled for 46/47x multis Posting pictures of current 02:30 run of Prime 95 Blend. http://valid.canardpc.com/show_oc.php?id=1745913

The 46 and 47 multi's are [email protected] Stable but fail at Prime Blend after a few hours.

VCCSA Voltage: Auto it's advised not to touch that one
VCCIO Voltage: Auto for now
CPU PLL Voltage: 1.75v
Auto PLL Overvoltage: Enabled
PCH Voltage: Auto
VRM Frequency: 350
Duty Control: Extreme
Phase Control: Extreme
Digi + VRM Current Capability: Auto - 100%
CPU Multi 47 by each core
CPU BCLK: 100 sb doesn't like changes in bclk
CPU voltage: 1.48v Manual
DDR Voltage: Rated stock volts
Spread Spectrum: Disabled
LLC: High or Ultra High (check which one works better for vdroop)

Test those with an hour of blend each time and reduce or up vcore when bsod.

EDIT: you might wanna get some new thermal paste

could help with temps and also keep the power saving featues on (doesnt effect overclock)

Run sfc /scannow and chkdsk /r and for all of you with GB mobos you should read this; http://www.overclock.net/intel-gener...uide-p67a.html

i say find max multi first...

Binning Sandy Bridge is extremely easy. - use HS fan with easy mounting - set Vcore to 1.55V - disable HT and 2 cores (to not make it overheat with crappy HSF) - increase multiplier You just need to see the windows OS options, not actually boot into windows. If your CPU can show the different OS options, stability will just be function of Vcore and temperature. If it doesn't show the OS options, you will never get it stable anyways, so you might as well ditch the CPU. Usually, it takes about 5 minutes to see if the CPU is good or not. With some CPUs, you do have the issue that some multiplier is better than the other for stability. For instance, my current CPU can boot at 51x MAX (~ 5145MHz). When trying to run near this max speed, I have to use 49x instead of 50x multiplier because it's a lot more stable. But, that's something

and then work your way through it maybe bump down the multi one and follow the asus guide

Interesting about the powersaving features. I replaced thermal paste.
So far so good on this OC with the 45x multi and 104.5 BCLK lmao

 

[seabiscuit68]

It is taking you 1.5v to get 4.7 Ghz stable?

I would drop off voltage to 1.35 or 1.4v and then see what you can get stable. Then I would stop overclocking because that is a piss poor chip

 

[munaim1]

drop bclk back to 100 and find max multipler as suggested by phaseshift. what thermal paste are you using now?

I don't know what they mean by OS options are they meaning in the bios?

Well the OC I'm doing with the 45x multi at 4.7 GHz is using 1.49v But I can get it 24/7 [email protected] stable with just 1.425v and that'll keep it Prime 95 Blend stable for about 2 hours. And yeah as I said in OP this chip can't compare to the first 2500k and motherboard I got, I just wish I'd never even thought of attaching that H50 >v< that screwed me over bigtime...

Anyways any more ideas?

 

[doughboy32]

I agree the voltage seems a little high for that multi. 1.375 gets me stable @ 48 multi.

[munaim1]

just noticed are you running 6gb of ram?

I would advise you to start from the beginning. put everything on stock and do this:

disable spread spectrum and run ram at default settings with rated volts.
vcore manual - 1.45
llc ultra high
phase extreme
duty control extreme
pll overvoltage enabled
cpu current 100%
turbo ratio by each core 47

dont change anything else

Yeah I'm running 3x2GB sticks of 1600MHz DDR3 Timings: 9-9-9-24-2T
I'll try it. Also why do you keep saying by each core? Wouldn't by all cores controllable in os be just as good?

I forgot where I read it but (I think) it does make a difference, im looking for it. In the mean time hope those settings work for ya. Post back and let us know. By the way I just wanted to ask, are you looking for max overclock on your chip or max 24/7? on that note whats the max vcore you will go up to?

 

[phazer11]

Max vcore um I'll go up to 1.63v that's what I did on my last chip but ofc I can't cool that real well lol so no Prime 95. Folding at home... maybe

And I'm looking for max overclock and max 24/7 so both.

OS boot options is just before the Windows Splash screen, usually if you have two OS installed it will ask you which to choose. Looks like the screen when you press f8 after post and you get to windows safe mode options.

put everything back into default in BIOS

and follow this guide religiously

http://www.xtremesystems.org/forums/showpost.php?p=4710467&postcount=2

^ follow everything on that to the TEE except for set your vcore to 1.45 and set the multiplier to 48 that should yield you 4.8ghz and do prime blend test for one hour.

watch the temps, if the temps get over 80C I would not keep it at that OC for 24/7 or lower the vcore. My i5 2500k runs 4.8ghz at 1.35v, YMMV.

- start at 48 mulitiplier
- set vcore 1.45
- follow the rest of the guide religously

I'm using the TIM that came with my V6 which someone in the HAF X Club believes is CM ThermalFusion so it should be almost as good as a new thing of AS5.

 

[phazer11]

Ok I tried that but... it BSOD'd with errorcode 124 when I told it to run Prime 95 Blend.

did you try those?

leave everything else and bump vcore to 1.48 and try again.

EDIT: before doing that remove one stick of ram and run 2 sticks at dual channel and then run prime95, if it fails then run memtest and then try with 1.48v

Ok will do try bumping it up to 1.48 that is lol and yes I did try those.

What are QPI/VTT on asus boards are those the memory controllers?

 

[phazer11]

http://valid.canardpc.com/show_oc.php?id=1747427
I'm trying it with the EPU settings enabled and it seems to be cooler even at 1.48v. I'm trying 4.8 GHz with 1.48 vcore and EPU enabled. Temps are only up to 66C.

 

[Viridian]

Anything over 1.38 is going to damage your CPU, regardless of whether you're on water or not. My friend has 4800MHz running 16 hours Prime95 stable @1.36v.

So if you have the money to burn go ahead and use a 1.5v overclock!

 

[phazer11]

No one really knows what will damage the CPU as they haven't been out long enough. Some people even say up to 1.45v is safe for 24/7. Right now I think 4.7 @[email protected] stable will be my 24/7. Right now I'm working on my highest overclock. Having the EPU enabled seems to help considerably with temperature which is the other half of the degradation story. Besides if anything happens in 2 years I'll just RMA again lol.

So any advice on OC?
