TPU's Core i7 Overclocking and Feedback

[t_ski]

Default on my 5970 is 1.049v.

whats vtt on turbo v?

QPI/Dram voltage

I don't recommend using TurboV for anything other than tweaking. Large jumps in voltage (> .5v) and bclk will cause the system to BSOD. I try to limit myself to no more than 5 small voltage changes before a restart. W7 would always BSOD if I tried to jump more than 5 bclk therefore I always use the bios to change bclk.

Use the bios for all big changes and TurboV for tweaking.

yeah i noticed i needed QPI/vtt 1.4v to get 2005Mhz on the ram but i just need 1.3v at 1600Mhz

i dont use it much to oc just to know my settings in the bios, i always oc in the bios im not new to ocing just i7 lol but looks like im going to have to hook up the phase cuz 220BCLK is all i cant boot at

so whats a safe VTT voltage on these i7-860's?? ive been looking around some say 1.35 some say 1.375 others have gotten 1.45 whats the general consesious

Not sure if the same as i7, but I remember trying to stay under 1.4 for daily use, under 1.5v for benching.

I bought a CPu cooler - Coolermaster Hyper 212 Plus.

I must say this is the best 30 Eur i've epent in my life. Lowered my temps by like 20C, now at 3.6 i barely hit 60. 4GHz here i come

Good luck man

I cannot get it stable on prime (something's fcked up with Prime), but, i've done 10 runs in Intel Burn Test on standard and it was stable. Prime and IBT give the same heat, infact prime is a bit higher.

21 x 191 @ 1.304V, temps are below 70 (70/68/66/63) in Prime, curently runing IBT with High stress level and the max temps are: 68/63/63/55.

Man this cooler is awesome!

 

[FilipM]

Crap, i was testing at 4 threads....:/



Edit: 8 Threads stable on standard, temps are a little higher


EDIT 2:

 

[Chicken Patty]

That's not bad man, you are getting somewhere.

 

[johnnyfiive]

People should start listing ambient temperatures when they have screenies with temperature results. I forget that I live in Tucson where its 75F outside and 25C in my house and then I get frownies when I think my temps suck.

BTW, nice temps Flip!

I tried that speed at 1.29375V in bios (two clicks down from my current 1.30625) and it failed badly.

Im surprised by the voltage requierement for 4Ghz though, 3.4GHz was at 1.128, 3.6 was at 1.168 so goin by this, 3.8 should be at ~1.208 and 4Ghz at 1.248. I guess it's not linear :/.


I also tried 4.1Ghz at 1.35V/1.30625 QPI and it froze.




Current stable settings:

21 x 191

DRAM - 1531
UCLK - 3063MHz
QPI Link - 6893MT/s

1.30625 Vcore
1.26250 QPI
1.20 IOH
1.20 ICH
1.64 DRAM

LLC ON


The rest is on auto (apart from ram timings)




PS. Ambient Temprature - 20.1C according to thermomether

If this makes you feel any better, to get my 920 D0 stable at 4.2 I had to use 1.35v, and 1.35v vvt/qpi. 4.0Ghz required 1.32v and about 1.33v vtt/qpi. This is 200x20 for 4.0 and 21x200 for 4.2, HT on of course. I considered my D0 to be a "hot one" in comparison to others.

Mine wont even sit on the desktop for 5 mins on 20 multi, lol



BTW, Batch is: 3927A448 - no one has this on the net except for me...(havent found anyone other than me). One over at XS has 3927A468

try 21???

 

[t_ski]

Johnny, my outside temps are between 5 and 30F, and inside temps (in the basement) are around 55-58F.

Thought I'd play with this chip a bit before I sold/traded it...

Let's see a LinX or OCCT run.

 

[p_o_s_pc]

here is my 24/7 settings i lowered them back to 3.7ghz because well idk why i did

 

[FilipM]

try 21???

I am at 21

19 works ok aswell, though i cannot boot at 210 BCLK

try raising the pci-e to 102. Should be at 100. Also give the ICH another notch of voltage or so.

 

[johnnyfiive]

Wow really? I think you even have the same board and memory that I had with my setup. C0 or D0 stepping?

Here was my highest 24/7 stable setup.

Scored about, 26k in 3DMark 06 with a 4870x2. Was cooled by a Noctua NH-D14.

As chicken patty has said, i7's are easy

 

[FilipM]

I lowered the Ram voltage to 1.62 and put the PLL on 1.86 and QPI to 1.24375 (i think), two clicks down on cpu votlage and its stable 10 runs in IBT on standard. (1.296V in cpu z, but it is less since it's set to 1.293 in bios)



EDIT: I tried everything, this is what i came to:



21 x 190

Ram - 1520 (8-8-8-21-1T)

Uncore - 2 x ram + 1

CPU Voltage - 1.29375

PLL - 1.86 ( i think)

QPI - 1.24375

ram 1.64
