Help with my i5 760 Build?

post #1 of 7
Thread Starter 
Hi, im very new to overclocking and this is the first high end pc ive owned, i looked through tutorials online and gave it a crack, i want to run some things by some of you more experienced guys here and see if everything in my build checks out

right now im running an i5-760 and i got it clocked from stock (2.80) up to 3.80
basically my setup is

Intel i5 760
Zotac GTX460 - 1gb
4GB of Gskill Ripjaw DDR 3 Ram
Asus Maximus 3 Gene Motherboard

My overclock settings are:

BLCK: 200
Multiplier: 19

Voltages
CPU: 1.3
Dram: 1.6
PHC: 1.00
PLL: 1.8

my fan is a cooler master hyper 212 plus (i filled out all my specs on my profile)

i put it under a stress test (ran prime25 and ffxiv at the same time)
the hottest it got was
Core 1: 58C
Core 2: 57C
Core 3: 56C
Core 4: 57C

i know these temps arent that bad, but im really new at overclocking and i want to make sure everything is good with my voltages and such, it seemed pretty stable (the game was very laggy well prime 25, msn, steam, utorrent, firefox, cpu-z and CPUID were all running, but i assume thats kind of expected under a max stress test)

im also wondering about my ram, i have Gskill Ripjaw 1600MHZ ram, now i know that most ram actually runs under stock (this is what ive read online) in my bios it was running at 1333 before overclock, now its at 1600, so i have it up to stock, also the volt settings on the site for it are 1.5, but i have it at 1.6 just for a little extra power... i dont know anything about ram timings or anything so if someone could help me with that i would very much appreciate it, thanks for the time and i hope somebody could give me some feedback, it would be much appreciated

Well if you are running the ram at its rated speed & timings you dont need the extra voltage.. That would do more harm than good.

Also what is your vtt/qpi voltage set to?

I recommend running Prime95 blend test overnight at your current settings. If it passes you can decide the next option.
1.) start lower voltages til unstable and then go to the lowest stable and be happy.
2.) overclock higher.

If it fails you probably need to add voltage to either the core or vtt/qpi....

i couldnt find my qtt/vpi voltages in my bios, i found qtt frequency, its set to auto and gave me 2 options 6407MHZ and 7202MHZ, which one should i go with? also where do i find those voltages?

and i saw at the bottom of my bios there was 2 things called CPU and PCIE Spread Spectrum, set to active, it said deactivating them could help to improve BLCK numbers.. what exactly do these do?

thanks for the help

I have always had spread spectrum disabled in previous builds, however I dont recall seeing it in my current..

Can you list everything you have a voltage option for?

Voltages
CPU: 1.3 <- this is the core
Dram: 1.6 <- set this to whatever the ram default is.
PHC: 1.00 <- this i believe is the southbridge, controls sata & usb, should not need to be changed
PLL: 1.8 <- 1.80v is fine, set it to that not at auto. Sometimes auto will adjust when overclocking.

But there should be 1 other voltage option. QPI - VTT

Here is a pretty simple guide for it - http://www.techreaction.net/2010/09/...ide-lynnfield/

the only other voltage i was able to find that i hadnt listed was the IMC voltage which is set to 1.113V (thats what it is when its on auto, but i put it in manually to lock it)

also should i disable spread spectrum (what exactly does it do anyway?) and what about that QPI frequency, its on auto now but i have the option to set it to 6407MHZ or 7202 MHZ, should i just leave it on auto or should i change it to one of them?

ill read that guide you posted right now, thanks, and sorry for late response i had to work

Update:
I went into my bios and upped the CPU multiplier to 21, so now its clocked to about 4.2GHZ
i didnt touch the voltages for anything (CPU is already at 1.3 and DRAM didnt increase because i only touched the CPU multiplier)
came back and ran intelburn and passed, highest any of my cores got was low-mid 60's

so now im gonna go and start lowering my cpu voltage slowly until i can find a stable one, i still cant find the voltages you asked for, and im still wondering what i should do with that QPI frequency (leave it on auto or change it?)

Update 2:
Looks like going under 1.3 blue screens me, i went to 1.28 and blue screened under stress test, so im just gonna leave it at 1.3 to be safe (ive read for my processor, anything below 1.4 is safe)

so basically just want to know about QPI frequency, oh, i also disabled spread spectrum (both CPU and PCIE) and it didnt make a difference, so ill just leave them off.. still no luck on finding QPI voltage, only one i can find is IMC

Also wanted to know about PCIE frequency, it was at 100 and i just left it there (its right under blck frequency).. should i bother changing that?

Final Update:
Sorry for all the updates, but i think i found a stable OC for me, im running at 4.0 GHZ, stress tested, hottest any of my cores got was 56C

CPU: 4000MHZ (stock 2.8)
RAM: 1603MHZ(stock 1600)

BLCK: 200
CPU Multiplier: 20

Voltages
CPU: 1.3
Dram: 1.5
PHC: 1.00
PLL: 1.8
IMC: 1.113

Soectrum spread is disabled and Load Line Calibration is enabled, like i said i passes stress testing, basically i just want to know what the QPI frequency is and if i should change it or not, also any additional advice would be appreciated, if not, im happy with this (i mgiht be able to push it farther, but im happy with 4ghz)

IMC will help with stability... IMC controls the bclk, you could probably set that to 1.26v or so and then try lowering your core voltage...

I recommend a long stress test. Prime95 Blend for a good 10 hours to ensure stability..

I have passed IBT 50 times at max and still failed Prime95 Blend... Usually a small bump in voltage fixes it...

And as long as you are stable leave the QPI Freq at auto..

okay, im going to try running prime95 today well im at work (10-11 hours), if im stable should i leave everything where it is? or should i up the IMC and lower the core? (is having the core where it is now bad or somthing?) because if not, ill probably just leave it like it is if i pass prime 95 when i get home
