i7 860 - Page 4

post #31 of 90
860 kills the 920 at stock, cause its clocked higher, and has more agressive turbo mode the 1156 i7 seem to be on par with 920 co in terms of oc'ing.

. Please If you want anything to be benchmarked, then tell me. I'll gladly do it. I don't do benchmarks very often, as they honestly mean nothing, not everybody has the same memory, motherboard, overclock, and other factors.

Here is the test setup
CPU: Core i7 860
RAM: Corsair XMS3 DDR3-1600MHz CAS9 (Don't give me hell about CAS9, please)
GPU: Sapphire HD 4770
Mobo: EVGA P55 FTW
CPU-HSF: ThermalTake V1 with OCZ Freeze

Lets start off with the CPU..

i7 860
I recieved a SLBJJ S-SPEC (B1), with a VID of 1.18, and FPO/Batch# is L927B308.
Right off the bat, I could tell I was going to be in love with this CPU.. Look at how nice she looks!

Anyway, put her in, and installed windows.. Once booted, i checked the CPU temp. 25c TCase.... 29-31c on the cores.. wow! Load, it goes about 55c...!!!

What REALLY surprised me was i took off the heatsink while it was idle... what the **** 46c? LOLWUT. Hmm, wow she runs cool even without a cooler lol! Load? did not test - do not want to lol.

I'm sure you all want to hear about how she overclocks..

I set the BCLK to 191, multi to 21 (Hopefully with the coming BIOSes you can use the turbo multis like the i7 920) CPU VCORE to 1.44 boot, and 1.42 final (after memory sizing), VTT (QPI/DRAM) to 1.425 boot, and 1.35 final.. PCH to 1.4 or so, and a few other settings. HT was on.

At first thought, i didn't think it POSTed, as it shut off, then it turned back on... went off.. (didn't look like it posted) and then came back on. looked in the BIOS.. Still said 2.8 GHz (stock). Got me real confused, but then i decided to boot. I opened CPU-Z and E-Leet (both use the CPUID SDK actually) and they both said 4GHz. I guess that was the memory sizing, and the CPU clock is set when it starts to boot.
So i started prime95 for a few hours and came back (about 11 hours into it) and it was still fine, and was loading @ about 80c. I do have a early screenshot of it.
I was very happy i could achieve a 1,200 MHz overclock (1.2 GHz) on my first try. I don't even have any references.
From what i know, the CPU Likes when you add:
-Vcore
-PCH volts
-PLL volts
-NB strap (i think its called that..) to be high
-stable RAM (I mean really solid, wont do anything when its over 1633 MHz, but will under that.)


How it compares to the 920
Honestly, the way i see it, the 860 is a Q9650 and the 920 QX9650. The 860 is like a 920, but with dual channel instead of tripple, and now has a PCI-E controller onboard. The 920 on the other hand, is marginally faster because it has tripple channel, and the QPI speeds can reach up to 7.2 GT/s (7200 MT/s) at a QPI link speed of 3600.. compared to the i7 860 which seems to operate at 4,8 GT/s or 4.27 GT/s according to the motherboard, or if CPU-Z is correct, 6.1 GT/s. Both are overclocked to 4GHz. Essentially, the link between the CPU and the northbridge (QPI) runs faster.. This means more bandwidth on the 920.

Basically, the i7 920 has more bandwidth than the 860, but really does not mean much from the way I see, they both preform almost equally.

If you want to see the build log with the motherboard, 4770, ultra 750w psu, and other hardware used reviewed, head over to my thread

Foxhound,

I just picked up my i7 860 today w/an ASUS Mobo...I am very interested
in hearing from you about how your overclocking on this Golden/First
chip off the line is going? I am a green rookie who is putting together his
first computer desktop sys. Can you tell me in layman terms how to
Overclock my chip w/o overcooking it? I did buy a Zalman heatsink fan w/a
Coolermaster HAF 922. Your help is much appreciated in advance!

Hi, cloud golf.

It would be good to know if you are familiar with overclocking in any sort.

Anyway, to overclock with this processor, you're going to need a bit of Vcore (CPU core voltage) which is usually found under the overclocking section/voltage frequency of your BIOS.

You need to change your Baseclock, BCLK (or as others call it, QPI) to whatever you want, as long as it is for say, under 191 (4.2 GHz/4Ghz). you can raise it if you want a higher clock, but after that, it starts to get hard to push it further.

here are some settings to look for, and set:
CPU Vcore - set to 1.400
CPU VTT (QPI/DRAM voltage, depends) to 1.35 or 1.375.
BCLK (or QPI) to 191 (or lower just incase)
and make sure you memory is going to work with your clock (e.g. can't be too high from what it usually is)

boot up and run prime95, you should be okay! It is a bit hard for me to explain, if you want to know in depth how to overclock these CPUs, visit the core i7 9XX overclocking guide. it is very similar to this.

http://www.overclock.net/intel-cpus/...7-920-4-a.html

Cheers

edit:
"overcooking"

don't worry, I would keep the Vcore under 1.47, and don't use Vdroop control (LLC) and make sure the temps are ~80c and below.

Thanks! I have never overclocked any CPU at all...a bit scared mate...I just dropped $1600 on my new system and don't want to ruin anything straight away. I saw you were very brave to experiment...even by removing the fan!!!????

Well, I did not quite intend to take it off, it was not properly seated, so i tried to push it, but the grease was holding it down, so i decided to pull and move it at the same time, but then it came off... saw the temp and was about 42-50c for a while.

anyway, there isn't much to worry about overclocking, its not going to destroy your CPU fast at all. It will be years. I guarantee. (sorta )

just check out that guide, you should be able to at least get 3.6 GHz or some other mild overclock.

I just picked all the parts up today and will begin building tomorrow...It's been a long, long time since I've tried building my own system. I'm sure I'll be slow going at first and then I can download everest or another genre of software to monitor temp's. I also have never overclocked any chip...so this will be very interesting trying to do something I've never done.

sorry for bump guys

anyway, you're going to wait for the 32nm variants in a few months.
