Overclocking my old i7-860 lynnfield

post #1 of 7
Thread Starter 
Hello gents,

So I have finally started getting off of my lazy arse and work on manually overclocking my i7-860 to 4Ghz.

So it is on my desktop intel build sig. rig.

Hardware for current testing:

i7 860 model: E stepping: 5 revision: B1 (stock 21x133 2.8GHz)
Gigabyte GA-P55-UD6 Bios: F11d
Corsair Vengeance CMZ8GX3M2A1600C9 (2x4GB 9-9-9-24 1600MHz 1.5V)
Windows 7 Pro x64 sp1
Antec 900 version 1 case with all fans running highest setting (3-speed antec blue led fans) 5 120mm and 1 220mm running..
Coolermaster h212 evo heatsink (might need to get something better lol.. from what I have read not much better than stock cooler)


First settings for testing:

multiplier: 21
bus: 183
vcore: 1.375v
qpi/vtt: 1.34v
plll: 1.9v
qpi: 6.87GHz
uncore clock ratio: 18x
uncore frequency: 3438MHz
qpi clock ratio: auto
cpu clock drive: 800mV
pci express clock drive: 900mV
cpu clock scew: 0 pico-seconds
spd: 8
pch: auto
intel turbo boost tech.: disabled
load-line calibration: auto (was going to change to level 2)
eist/c1e/c3 and c9: disabled
multi-threaded (aka HT): disabled
all 4 cores enabled
turbo mode/cia2: disabled
xmp: disabled
memory: turbo mode
timing: stock 9-9-9-24 (spd clock set to auto)
memory voltage: 1.56v

Have SMART CPU fan control disabled so the fan runs at high speed 24/7..

pictures soon to come.. doing a CPU:OCCT 2 hour 64 bits large data set stress test... about 30 minutes into the test the core temps from ope hardware monitor registering MAX at 86C, 86C, 82C, 90C.

Any suggestions on lowering the temp? I was thinking of getting a CPU water cooler for it... I use to use a swiftech triple rad kit on my old dual core setups... Is it worth it or is air cooling good enough??

**EDIT#1**

It seems that OCCT v4.3.1 says Core #3 over maximum value ! Value Reached: 86C, Max Value: 85C... So it seems I need to get a new heatsink be it water or air...

Maybe this heatsink would fix my heat issues lol... Thermaltake CLP0587 140mm CPU Cooler

**EDIT#2**

Okay new settings changes are:

vcore: 1.36875v
qpi/vtt: 1.3v
dram: 1.54v
bus: 191MHz
stock idle temps getting around: 40-45C New cooler and thermal paste is going to have to be a must... 8(

**EDIT#3**

So I am sure that I dialed in at 4.0GHz a good setup...however without a good cooler I am sure I cannot keep those settings currently.. Soo I was thinking what I can reach on air checking 3.6GHz as a good starting point... staying between 75C to 80C full load OCCT infinite test... vcore 1.35V, vtt 1.3V, dram 1.54V.. 2:8 ratio... I am thinking that if I can get a 1:1 ratio with the memory I could benefit between 400 - 800 MHz core frequency on the CPU and maybe a 10-20% RAM performance increase...

Okay so I did get some new stuff to cool my cpu better. Here is my i7z snapshot from Arch Linux with the settings from my previous post. Still unable to get the RAM about 1600MHz I think the vengeance I got are just duds...

I am using a Thermaltake Frio Extreme and a Lanboy Air with 9x120mm tricool fans all on hi.

80-90 degrees is really not that hot for Lynnfield CPUs, but you can try to reseat the cooler and clean out the dust in your case. When I overclocked my i7 860 I had those kind of temperatures too, and I have a watercooling CPU. I don't think you need to worry too much as long as they don't go that high when you're gaming and such (and not stresstesting with Prime etc.).

It is a bit too hot for Lynnfield.

 

adramalech707, the temps in the second pic look good for idle, how does it do under load now?

Okay so I clocked it down now because I switched spd to 10.0. So my RAM is running at 1.54v @1860MHz.




Give me a little while to run mprime and see what the temps are then. thumb.gif

**EDIT**

Okay so I am running System Stability Tester version 1.5.1 and so far so good.

I am doing 4 turns, 64M digits, with 8 threads on a Gauss-Leg. algorithm on loop2 right now digit 4, and temps are not spiking above 65C. staying between 55-65C at peaks. Seeing mostly mid 50C as the median.

This is of course at 3.906 GHz with BCLK at 186 MHz. I didn't want to suicide my stupid ram at 1910 with SPD 10.0 and didn't like the SPD 8.0 RAM frequencies so I have stuck with a litle bit shy of 4.0+ GHz but have faster RAM performance.
