Intel Inside

post #1 of 2
Thread Starter 
Quick rundown on what I'm using here:

Gigabyte GA-Z68XP-UD3 Rev. 1.3 F9D Bios
Intel 2550k Core-i5 Sandy Bridge
16GB G.Skill Sniper F3-12800CL9Q-16GBSR
Noctua NH-D14 cooler with included fans
Antec Twelve hundred case (why replace it, it's big, it's roomy, and it has a ton of cooling already there thumb.gif )
-Fans in the case include 3 front fans, 1 behind the top set of 3 bays in front of Noctua, 2 rear exhaust fans, (all 120mm fans except one on the Noctua that is 140mm) and one 200mm top fan.
1050w coolmax PSU
PNY GeForce GTX 560Ti
1x 600GB WD 10k rpm raptor - haven't set up raid array yet
2x DVD/RWs

So I've done a little bit of homework and some reading and found this process is a bit different but relatively similar. I don't feel I really understood what I was doing, but my last build (which was my first build and OC) ran at 4.0GHz on air so something went right. I want to get more of an understanding for it this time.

I've went through The ULTIMATE Sandy Bridge OC Guide + P67A-UD7 Performance Review and [Official] The Sandy Stable Club **Guides, Voltages, Temps & BIOS Templates** Inc SPREADSHEET for some up to speed, up to date info.

Here is where I am at:

I have HWMonitor, CPU-Z, SpeedFan, Core Temp, and Intel Burn Test.

I checked my stock VCore:
448

I disabled real time ratio change in OS, Turbo Mode, C1E, EIST, C3, C6, CPU Thermal Monitor
I enabled internal CPU PLL overvoltage option

I raised the multiplier to 45X - boots to bios and to OS - recorded the Vcore
448

I raised the multiplier to 48X - boots to bios, not to OS - recorded the Vcore
448

I raised the multiplier to 50x - I got the notorious gigabyte boot cycle, failing to POST until CMOS is cleared.

This is the easy part sure, but its also where I start getting that glassy affect going when I keep powercycling adjusting settings to try and get stable.

So I'm basically at the Voltages section of The ULTIMATE Sandy Bridge OC Guide + P67A-UD7 Performance Review

It's not that I don't understand the rest of this - I am just already starting the perpetual cycle of not knowing exactly what step to take after finding those Vcore's and what voltages to set where, when, why and in what order. Yeah, another newbie, but not totally. I got the hang of the tinkering part just enough to be dangerous. Now I want to be able to understand it just enough that I can know why X affects Y and Z gives me the bird. biggrin.gif

Here are some additional screens of what I see:

can you updated your BIOS for me tto the latest, it should help with your boot loop: http://forums.tweaktown.com/gigabyte/28441-gigabyte-latest-beta-bios.html

So you want what 4.8 or 5ghz stable?

you got oto 4.8ghz without changing the vcore manually? i guess that is teh beauty of SVID, see that current vcore number i am guessing is 1.344v, try setting 1.35v and LLC level 7 see if you are still able to do 4.8ghz into windows, and see how stable you are.

BTW what are your temps?

SB OCing is very straight forward, increase multi, disable power saving if you want, set vcore, if you want you can try dvid, make sure pll ov is enabled, set llc. Increase multiplier that is about it. for the CPu part at least. You can also lower CPU PLL to 1.6v if you chose, it might help it might not.
