Core i7/X58 Overclocking Thread

As the title says post your experiences and recommendations for OC'ing Intel's new high end processors.

Here's mine:

We finally got hold of a CPU cooler (Akasa Nero) with LGA 1366 mounts today, so we put the Ci7 and P6T together. We tried every type of DDR3 we had available but it would only POST with GSkill NQ (Not Quick?).

We didn't like the look of the fan that came with the Nero (0.08W) so I grabbed a YSTech monster (8.52W) that has served me well in the past.

Test Setup:
Core i7 965
ASUS P6T Deluxe
6GB (3x2GB) GSkill NQ DDR3 1066MHz 1.6V
Akasa Nero Socket 1366 Direct contact HPC with 8.52W YSTech fan Thermalright thermal compound (as supplied with TRUE 120)

Cannot post anything in depth for fear of NDAs etc and because rummaging for compatible RAM and dealing with more mundane systems (water cooled Xfire 4870x2s) got in the way.

Anyway, 3.6GHz was pretty much free and 4.2GHz is within reach but this HPC probably wont get much further. We should be getting 1366 brackets for an XPSC Delta next week and hopefully it wont be too long before the TRUE ships with 1366 brackets.

Why couldn't this thread wait until post-embargo?

Anyways, it doesn't belong in Xtreme Overclocking either way.

I love XS! An X58 overclocking thread before the Core I7 NDA is even lifted!

well ppl

dont keep your hopes up

i just read an interview with some intel guy today, and he said only then first batch of ci7's will be overclockable.... and they wont be good for gaming either because they wont do floating point very well.

he then goes on to say that in the future they will release true high end ci7's that will be overclockable like buggery and game like never before... but at a price premium. (he said the price difference would be like the gap between core 2's and the core 2 extreme's today :mad:)

well that is if u can believe every interview u read

my i965 run great at 1.30V with AIR COOLING at 3,9GHz Prime95 stable ...
second i920 is pretty stable at 3,6GHz with AIR COOLING and base clock at 170MHz ...
best choice for money/value is i940, is overclockable to 3.7 - 3,8GHz on AIR ... with best mobo

From what i've read the CPU OCs itself in situations where only one core is needed and that it OCs itself to 3.6Ghz. Thats what i read in the current issue of Maximum PC anyway.

Well someone had to start it. I'm guessing that this thread will eventually become part of the ** Oficial ASUS P6T Overclocking Thread **

So far I am happy with the OC performance of the board and CPU but not so happy with the cooler, basically as soon as I launch Prime95 the temps leap 40-50C and the system crashes. On the bright side the XSPC Delta bracket turned up so it'll be getting proper cooling soon.

That's by changing cpu multi I guess.
Because the unlocked cpu is too expensive, I would like to know what frequency you can reach without cpu multi. Just raising the base frequency...

hm... well if they wont overclock.. or be that great until later and at prices like th Core 2's vs Core X's.. then I'm MORE THAN HAPPY to stick with my Q9650 thats Flying at 4.2 ghz no problem. and more to come.

but I'll wait and see the Real true results from these things.. as I can't ever trust what I read until I actually see REAL results.!

Well, if thats Intel's new overclocking policy, I'm sure that AMD will start putting out dirt cheap overclockable "great for gaming" chips down the road...

Hooray for AMD!

No, both of those were with the multi knocked down to 20. Base clock goes up to 200 easily and you can probably guess what the most I got out of it was.

As for comparisons to Core2 Quads, they are both 45nm with High-K gates and they clock about as well as each other the unanswered question for me is the performance improvement from the Ci7 architecture, SMT & Tri Channel memory.

You'll only see big performance improvements (ie. 10% or greater) with Nehalem if you run software that makes proper use of 4 or more cores vs. current chips. This is what some have been alluding to by saying it won't be that great vs. current chips for gaming, performance will probably be almost equal on a per clock basis. The only games where this might not be true are UE3 based games since that engine supposedly is the most rigorously multi-threaded out there ATM. Allen Wake should benefit quite a bit too when being ran on Nehalem vs. current quad core chips. Since over clocks aren't all that much better either if you've currently got a quad or even dual core chip at or over 3Ghz Nehalem probably won't be worth it for you're average gamer until it gets (much) cheaper and/or agressively multi threaded software becomes common place.

Where Nehalem will truly shine is server workloads and heavy duty scientific number crunching. Its really meant for that market, it just happens to perform well on desktop apps/games too, much like K8 was in its prime several years ago.

Core i7 920 @ 3,9 GHz (prime95 8-thread stable), air cooling

I have just managed 3,9 GHz with a Core i7 920 ES (3,8 GHz without Turbo, both settings prime95 stable, screenshots below) and Asus P6T Deluxe. 1,35 V Vcore was enough for 3,8 GHz, about 1,41 V for 3,9 GHz. Not bad for basic Bloomfield :-). Other settings:

QPI: 1,4 V
IOH: 1,35 V
ICH: 1,4 V
speedstep, turbo: on (for 3,9 GHz), off (for 3,8 Ghz)
virtualization, C1E: off
spread spectrum: off

memory (qimonda ddr3-1066, cl7, 1,5 V): trichannel, about 1200 MHz, 9-9-9 (8-8-8 was stable tool), 1,64 V, 3N for sure

Well, considering that all games coming to PC now are pretty much multi platform, ps3/xbox360/pc, games have not tested current hardware much, except for a few titles like STALKER CS, and CRYSIS, other than those 2 pc exclusives, all other games are console ports with some "enhancements", xbox 360 and ps3 will see life into 2010, ps3 should be staying till 2012 from what i have heard, so you can imagine games and graphics cannot change much, plus we have hit a wall in graphics somewhat, where there is not much to improve, maybe ways to render faster and better ways to optimize games and such..... My point being, dont expect much games to come out takin advantage of 8 threads, there is only a handful of apps that take advantage of more than 2 cores, yet alone games. Most games are still single threaded.

Ufon the reason i ask about the temps is on that link of yours real temp says 89,89,85,85 and core temp says 92,92,85, 86 , im used to with my quad max temps when folding are 56c max, so does core i7 run that hot or those temps wrong ?

also what is the intel recommended max temps for the core i7 920 ?

I would like to know this aswell. But IIRC Nehalen has temp monitor hardware INSIDE the chip, so it may very well report higher temps than what we are used to. Maybe not coz its hot in comparison with current chips, but coz it monitors the ACTUAL core temps.

This is just an educated guess based on info about the temp sensor, so it would be great to know more about it from Drwho :)

Bloomfields are really hot. Thermalright Ultra-120 eXtreme is not weak air cooler and the temperatures are high even without overclocking. But I'm not sure about the correctness of RealTemp/CoreTemp numbers....

Turbo mode unlocks the multi ?

Thanks ufon , can I assume the difference is even greater at higher clocks ?

No,it bumps the clocks my raising your multi plus 1 and throtling the other cores(I think)

It raises the multi plus 2, it can be set manually without throtling the other cores or anything that the AUTO function would do. You can simply raise it by 2 :)

So it is a fake Multi 22 ???? I only have 21 !! He is also registered WR holder in www.ripping.org then this is also a fake ?

No, it is not fake, turbo mode will take the CPU up to 22 if you are in single threaded mode, it will go back down if you use more than 1 core.

2 Bin turbo up if single threaded, 1 bin turbo up if multithreaded, of course, it is only if you do not product more thermal power than what is set as TDP.

So if you have one single threaded benchmark you can always count on the +2 turbo, and a multi threaded benchmark will fall back on +1. Might be handy in a few cases to force the affinity on one core if it's multi threaded but both threads don't place more then 50% load on a core? Not sure, can't know now can I :rofl:

Makes some sence, some benchmarks benefit from mhz but don't load a core fully.

5 to 10% OC is not that much is it ?...my 286 was going from 10 to 12 mhz with turbo mode :D
would 20% be too much technically due to modifying other parameters in bios?

btw would it make sense to deactivate HT and remain quad thread to lower voltage / wattage need of the platform or would it be marginal ?

so how long turbo mode last? a few minutes, a few hours, or many hours as long as only 1 or 2 cores are used?

So basically you're saying it takes the CPU to 11? Sorry, couldn't resist :D

Try to run CpuZ right after Windows booted or try to load only one core and then keep eye on frequency and multiplier ;-)

If you don't know how it doesn't mean it's fake (for others: it's a little bit of rivality in Czech rep.). For such purposes is here CpuZ validation.

According to Tom's Turbo Mode is only for the extreme edition. Don't know if that applies to the models being tested now.

It can't be forced at all :-). Some tips and tricks:
1. Turbo works according to load and temperature (?)
2. Right after Windows started, run Cpu-Z
3. I personally get the max. freq for CpuZ with Prime95 25.6, 1 thread, Blend, but it's possible to get mult. 22 without it - Vista boot (and loading of drivers and background running apps) generates some load which should be enough
4. Save your CpuZ validation file every second to another file - in one of this files could be the highest frequency - in my case multiplier 22 appears for short time every 10-20 seconds

22 isnt real for quad core aplication. When you launch prime95 , wprime or cinebench it goes down to 20X.

People you are all posting awesome overclocks... but what about the Overspeed Protection? Shouldn't it limit your OCs to 100A and 130W (except for Extreme versions of course)? If not, how can it be possible?

There is a program LINPACK for solving systems of linear algebraic equations [treatment matrix?]. Result Gflops. LINPACK 64: Q6600 @ 3000 ~ 40Gflops. Core = 10GFlops = 40Gflops/4.
There is a maximum result 106100 GFlops (106.1TFlops). 8200EX = 2560 * E54xx. At the core of 10.36GFlops (106100/10240 or 106100/2560/4).
LINPACK 64 or 32: Core i7 GFlops?

4.2 ghz i7 920 very nice.

is that 80* c loaded stock cooler or just idle?
Is it stable?

How much is it consuming?

From reviews overclocking that high caused a 50w increase idle and 150w increase load.

Which would mean it'd be hard to air cool it?
With that on top of TDP I feel like even a TRUE would get toasted.

Also what's the highest voltage via Intel Specs?
Through all this overclocking I didn't see anyone mention that oddly.
I would think it'd be on the box.

I read this at Overclockersclub:

"To keep the CPU from throttling under load you can increase the "current limit" override as well as the "power limit" override in the DX58 Smackover motherboard BIOS."

Edit:
On any decent motherboard, this option should be available in the bios for any Core i7 CPU.

Yes it is hard to air cool, limited availability of coolers doesn't help either. I believe the key to breaking through to 4.5GHz will be keeping the thermal transients low.

firingsquad's review make it seems like, due to the turbo mode, its possible to permanently set the multi up two notches with 4 cores enabled, without the automatic changes going on.

Not 100% sure yet of the details of how that works exactly. How much control do we have over this feature etc... Can anyone link me to something reliable that explains it all ? Thanks

EDIT: After reading some more, it seems like those who cant keet the multi up with 4 cores activated may he hitting the Power Control Unit temp ceiling.... I wonder if they were water cooled it would be possible to keep the multi up by 2 w/ all 4 cores activated and loaded.

Or the Turbo mode multi changes can only be dinamic, relative to the workload instead of temps ?

The CPU-Z gif in the link shows the multi changing depending on the PRIME load, but I dont know if rising temp is the cause:

I am to be VERY VERY clear, there is not Overspeed Protection, we have a BIOS setting to bypass the PCU control of Current and Power. On smackover, it is call "CPU VR Current Limit Override", and it will allow you to bypass the thermal and courant limites on the Core i7 920 ans 940. Who ever claim the otherway around did not read the specifications enough :) hehehhe
we have recommanded to the motherboard makers to follow our steps.
So, relax, and don't worry ...

I guess Tom forgot to read the manual? So with that said, is there any reason to get a 940 over a 920?
