The Intel Core i7 Overclockers Club

zAAm · May 28, 2009

I wondered why nobody has started a club like this since the Phenom guys have their own...

This club is for everyone who OWNS an overclocked i7 920 (940, 950, 965 and 975 users can come as well although your sanity will be questioned

). I suspect that most i7 owners overclock theirs anyway.

Please post your thoughts on the processor on anything from value vs the new i5, motherboards, performance vs other processors etc.
Overclocking information will also be welcome since the i7 overclocking thread is absolutely HUGE and you can't get any useful information on there anymore...

A handy crash course in i7 overclocking is available here: Core i7 Overclocking Basics

If you want to join, just PM or post clearly the following details to me: (If not in your system specs)

RUNNING Frequency (not your maximum overclock, the clocks which you normally run your i7 on)
Base Frequency
Voltage
Stepping
Motherboard
Memory model and speed
Cooling

Please try to send all the info to me, otherwise the field will be blank

Additional Information (Under construction )

Common steppings:

C0

First stepping used on the first production CPU's. Overclocks mildly although some users have had pretty reasonable results of > 4.2GHz.
D0

The newer stepping for the i7. Generally overclocks higher than the C0 i7's with less voltage. 4GHz is a standard overclock for a D0 on decent air cooling.

Cooling:

Air cooling

You'll need proper cooling to overclock the i7 since they are hot as hell by default. A few types and pictures can be found here: Air Cooling Club
Water cooling

If you want to go up a step albeit a pretty expensive step, try a watercooling setup. It is recommended to stay away from cheaper watercooling kits since high-end air coolers gives comparable performance for a lot less. A few types and pictures can be found here: TPU Water Cooling Club

not 100% but I think there is

TPU's Core i7 Overclocking and Feedback

It may not keep track of peoples achievements but there is definitely a thread about OC'ing i7's.

zAAm · May 28, 2009

Like I said, that thread is for anyone, this is for owners only and hopefully this one can give a new user an idea of the overclock they can expect

What I'm trying to do is make it easy for new i7 owners to see what they can expect on average if they want to overclock their cpu. I tried to make sense of that thread but it's just not worth shuffling through 118 pages to see what experiences people have had with the chip. With this thread I can sum up the type of overclocks people got and then newcomers (like I was) can see it quickly and easily

Jaffakeik · May 30, 2009

can i join club pls

zAAm · May 31, 2009

Sure, just PM your details to me and I'll add you

human_error · May 31, 2009

My details are in my system settings. You can add both my 24hr and overclocking numbers seperately if you want.

Info not in system details:

My memory type is Corsair ddr3 xms3 (stock settings for ram were 1333mhz, 9-9-9-24)
My Stepping is C0
My Multiplier is 21
I am using watercooling still with a DD MC-TDX i7 edition cpu block.

zAAm · May 31, 2009

Added, and welcome to the club!

Assassin48 · May 31, 2009

my stuff comes in tomorrow so i guess
17 920 D0
Gigabyte UD5
Samsung 3x1gb

heatkiller block<-- later this week

Keep us posted as to the overclock you get with that D0! I'll add you the moment you have some more information on your system :cool:

Edit: added you anyway, but will update your info once you get more

Jaffakeik · May 31, 2009

Zaam add to voltage 1.280V >base clock 191.15mhz>mutiplier x21>memory frequency 764Mhz>clocks 9-9-9-28
and update CPU frequencu to 4011mhz

TY mate

zAAm · May 31, 2009

Done. Do you run @ that speed 24/7? What are your temps like?

Jaffakeik · May 31, 2009

No i run it about 10hours+- a day but its set on automatic core regulator when i do lil work wit my pc core clock is lower than 4ghz when i in games its got 4ghz+. cooler holds my cpu on 40C in all cases because it got auto profile to hold such temp.and add corsair cooler for my memory

mudkip · Jun 1, 2009

add me :

Core i7 920 D0 @ 4,2 Ghz
Rest of the info :

zAAm · Jun 1, 2009

Done, lol @ "Fuck i5"

mudkip · Jun 1, 2009

I love low voltages

current tweaking for even lower vcore

Chicken Patty · Jun 2, 2009

funny if you go below 1.000v :laugh:

Maby if I go for 3 or 3,3 Ghz but won't happen with 3,6

lower yes, but at 3.6 GHz, I dont know :laugh, you are pretty close man.

mudkip · Jun 3, 2009

bump!

zAAm · Jun 3, 2009

1.1V on 3.6GHz is just insane! Just a question though, are you undervolting just to check the stability of the cpu? Or are you trying to get a sort of sweet spot where the heat/performance ratio is better?

I don't know much about the uses for undervolting except reducing power consumption and heat output. But this usually goes with underclocking. Now your overclocking/undervolting... New experience for me I must admit

I just wanted to see how much volts I'd need for 3,6Ghz . so here I am 1.10v

I'll check how much volt I will need for 2,8Ghz , which is comparable with stock 920 + turbo mode.

good night young fellas

Joining up!

Currently running at:
Frequency - 3.75Ghz
Base Frequency - 188Mhz
Voltage - 1.18v
Stepping - D0
Motherboard - DFI LP DK X58-T3eH6
Memory model and speed - OCZ Platinum, 6x2Gb DDR3 1600Mhz running at 1500Mhz CL7-7-7-20-1T
Cooling - Scythe Mugen II with a pair of 120mm Scythe Slipstreams.

I think I'll start my own low-voltage expedition over the weekend, I lowered my OC from 4.2Gh to 4Ghz and now to 3.75Ghz since the ambient temps are climbing through the roof (And at 4.2Ghz with 200 BCLK and Turbo Mode on I needed around 1.33v, and with nearly 40c ambient load temps would shoot through the frakkin' heavens towards the 90c mark !), but I haven't really tried a lower vcore at my current settings. That 3.6Ghz on nearly 1v is just insaaaaaane and has my total respect ! :rockout:
