Im going to require help from the community for my 1st overclock in 4 years lol but first i want to check these stock temps

Just checking that my rigs stable at default currently and running prime smallfft

Idle temps were 34 31 35 31
Load temps Settled at 55 52 55 51

1.192 vcore default

Temps seem right for stock?

Yeah, no worries.

A very easy overclock, just increase the blck speed to 200 for a 4ghz CPU. No need to go up a little at a time etc.
 
Right starting prime96 at 0.98v stock speed on small fft

I know i should do it for hours but im currently just stressing on 25mins runs


Load temps 46 43 46 42 @ 0.984v stock 2672.7mhz small fft prime 95


Im gonna need help setting the memory up as i have no idea how to do it

Definitely get an aftermarket cooler, voltage wise, i was fine on 1.18 upto 3.6ghz, needed a jump to 1.2750 for 3.8 and 4ghz.
 
running IBT at 0.98v stock 2.672.2 mhz at the moment

GOing to drop the v down to 0.8 next

Seems IBT isnt pushing the cores past 44 41 44 40
 
i can get 3.6Ghz @ stock voltage (1.1V) the temps are so low (45ish linpack) im currently running this as my 24/7 clock.
To get 4ghz i had to bump the Vcore upto the 1.3V mark and the temps were in there 60's.
It matters what you use your PC for tbh as i only do a little bit of encoding, mostly gaming and web, i dont really see much of a benefit at 4ghz, also as im running the P6T-SE the cooling for the motherboard is pretty poor so the chipset and mosfets were cooking at higher clocks
 
im taking baby steps and seeing whats the lowest vcore i can get it at

3ghz at 1.04 seems stable according to IBT and a quick 25mins prime 95 run on small fft

partway into my prime run and temps stable at 52 49 52 48
 
Your chips stock VID is 0.984v??

That's really good, you're using CPUZ to monitor voltages under load right?

I know at stock my chip sits at 0.946v idle, but once I put a load on it shoots up to 1.163v.

1.040v for 3GHz is pretty good to, as is your temps..

I find it's best to do what you're doing, and work your way up to 4GHz. You might find that once you start pushing past 160Bclk that you will need to start giving it larger increases in vCore to stay stable, unless of course you have a really nice chip that only needs 1.18v for 4GHz!

IBT is fully loading your processor right?

You're using the maximum amount of available RAM for testing?

I always find it's best to get your system stable with at least 20 runs of IBT or LinX (they're both much and such the same, I personally prefer LinX) using all available RAM, then once that's stable, let Prime95 run overnight, if it's still running in the morning, I start playing games, encoding, browsing etc etc for a few days, and if I don't experience any BSOD's, system freezes then I class that as stable..

Everyone has their own methods of stability testing though.. but 25 minutes of Prime95 won't give you any indication as to whether you're o/c is stable. :)

This is the method i would reccomend, start small, get it stabe then you have a known stable base to work from.
 
i do know 0.85v at 3ghz doesnt work :) i got cocky, it wouldnt boot

Using max ram available and its loading the processor

I know 25mins isnt good but im using that timeframe to judge if its horribly unstable or not.

im aiming for 3.5ghz 24/7 so once i found the lowest vcore for my intial tests ill run it overnight. once thats confirmed ill go for 4ghz
