I say 20 IBT on almost max is enough for general stability

Except that IBT doesn't stress test SB. I've passed 500 runs of IBT on maximum, only to fail 30 seconds into Prime. All IBT does is get things hot, that's it.

And I have had Prime runs fail at 9-10 hours in or so, and they'll give me random blue screens doing simple tasks. If I pass 12 hours, I never have a problem at all.


That's because it takes nearly 18 hours with our SB chips to hit every FFT that Prime95 has before it begins to recycle FFT lengths if you're doing a blend test or a custom blend test and you leave the FFT time at 15 minutes. There are 72 FFT lengths P95 will test and at 15 minutes... do the math. :)

 

If you want a quick and dirty rough guess stability test, you can reduce the FFT times to 1 minute and then allow P95 to run for 72 (more like 85 due to some weird core latency balance issues) to cycle through each FFT a minute at a time. There are two FFT lengths that stress the SB in ways that seem to cause the most errors: 1344 and 1792 and you won't hit both of those in a 2 or 3 hour blend test unless you change the FFT time.

 

So I'm going to have to agree with pioneerisloud: IBT gets things hot and is a rough indicator of maximum power consumption and can be very useful for watching maximum Vdroop and also tuning your voltage as low as possible for a given clock and seeing what sort of impact that has on GFlop/s performance. I know that at my previous 4.7 GHz OC, I was hitting some internal throttles (remaining at 4.7 GHz though) and my GFlop/s were much lower than they are now, with a reduced core voltage. IBT helped me tune that aspect of my OC.

 

However, for stability, IBT was darned near worthless, as the only things I've found to truly test stability were an 18 hour Prime95 Custom Blend using 95% of my RAM (and hitting on every FFT length for 15 minutes) and then 24/7 SMP folding.

 

I thought I was stable at 4.8 GHz. I wasn't truly stable until I backed down to 4.7 GHz. Then I tuned my voltage and LLC to as low as possible to remain stable and have the most power-efficient performance possible, which increased my GFlop/s, my benchmark scores, and my PPD on Folding.

Running 48x myself at the moment.
Haven't bothered stress testing tbh..

It's been fine running 24/7, gaming, movies, browsing, whatever for three weeks or so now.

I did have a lockup during my screen saver last night apperently though, I just can't be assed. ):

Honestly think that's more in your head than anything else.

How do I disable ALL throttling btw?
Atm I'm getting 16x idle, and 48x load.

So, by using my "fix" of putting the video card (GTX 560 Ti) in the black slot, x2 speed? I haven't noticed any reduction in visual quality/framerates afterwards. I'll check CPU-Z and GPU-Z when I get home to see what they say, though I'm hesitant to mess with it. It's been stable for a while now and I don't want to return to the world of repeated bluescreens.

The black slot is x4 on the LE. You have the same issue I have on the GEN3, a defective x16 slot.

x4 is good for a theoretical 2GB/sec, compared to 8GB/sec on x16. If you're not going to RMA, I guess there's not much point in worrying about it though...

but here's a recent article on the bottleneck for a faster 7970:

Hi guys, I am building my first ever rig since back in the 486dx days and was looking for a little advice as I get up to speed with all of the current hardware thats out. The PC will primarily be used for picture editing with Photoshop and Lightroom with some gaming thrown in on the side. I already picked up an i7-2600k as well as a Corsair H100 for some cooling. I narrowed down my search to the P8Z68 DELUXE/GEN3 and P8Z68-V PRO/GEN3 boards as I wanted PCI 3.0 and a GEN3 board. I need this PC to last me at least 4-5years and was looking for a little direction.

Current Components Selected:

Motherboard: P8Z68 DELUXE/GEN3 or P8Z68-V PRO/GEN3
CPU: i7-2600k
CPU Cooling: Corsair H100
GPU: Will be waiting for the GTX 680 to be released
RAM: 16GB Vengeance unless someone has a better recommendation
SSD: 256GB M4
Power Supply: NZXT HALE90 1000W
CASE: NZXT Phantom

If I go with the PRO GEN3, I can use the onboard video for the next month or 2 while I await the new Nvidia cards to be released (apparently Photoshop runs better on cuda). If I go with the DELUXE GEN3 then I'd have to buy a cheaper hold over card that will last me a couple of months that I can hopefully reuse in another PC.

Outside of the lack of onboard video capabilities, what other features/advantages does the DELUXE has over the PRO model that should make me choose the DELUXE model over the PRO? This will also be my first time delving into over clocking so I'm not quite sure what to look out for in the different boards yet.

The GEN3, and Pro GEN3 have onboard video via the CPU. You mentioned wanting PCIe 3.0, so be aware, you must have not just a PCIe 3.0 motherboard, but also a PCIe 3.0 video card, and an Ivy Bridge processor.

Otherwise, with the 2600K you have, all three boards are PCIe 2.0 x16 single card, or x8 for SLI/CrossFire

Sorry I wasn't clear. I primarily wanted the PCIe3 and GEN3 for future upgrade paths in the future into Ivy Bridge. I would love to wait a few more months for Ivy bridge to come out but I need a new PC now and the 2600k recently went on sale which pushed me to purchase. I know I am purchasing and building at a time where new cards and processors are just around the corner so I figured it would be a good time to choose a board that would let me upgrade later without too much hassle. In my eyes, I could always upgrade video cards, RAM, and CPUs easily but not so much with the motherboard which is why I'm having a hard time deciding between the 2 boards.

The Deluxe GEN3 does not have DVI/VGA/HDMI and would require me to pick up a new video card right away.

On the RAM:

 

You're wasting your money, electricity, and potentially hurting your OC performance if you install 4 DIMMs for 4x4GB = 16GB of RAM.

 

You're going to get better performance from a faster 2x4GB = 8GB of RAM in a dual-channel motherboard. I can give you a very lengthy explanation on why this is, but the long and short of it is that completely filling the DIMM slots with RAM puts a heavier load on your memory controller, introduces more latency into your system, and causes your system to under-clock your RAM and/or reduce your RAM timings.

 

I suggest that you go with a 1600 or 1833 set of RAM in a 2 module configuration. Unless you are editing extremely large image files (in Maya for example) , working with autoCAD (or some other autodesk product), or doing heavy video editing in 3d studio max, or something else that requires gobs of system memory, then you do not need 16 GB of RAM, will never use 16GB of RAM and will only be hurting your performance if you install 4 memory modules in your motherboard.

 

With RAM, more is not always better. Even going with 2x8GB = 16 GB of RAM in just 2 DIMMs (if you can afford it) will put a heavier load on your memory controller due to the number of chips on each DIMM.

 

The ideal amount with modern games and Windows 7 (or even Vista), while still allowing plenty of headroom for future applications is between 4 GB and 8 GB of system RAM. For me, 6 GB was ideal, but since DIMMs come in 1, 2, 4, and 8 GB configurations, I went with 2x4 = 8.

 

The extreme overclockers setting world records usually go with 2x1 = 2 GB because they can get insanely fast frequencies and timings out of it and because it puts such a low draw on the voltage and current regulation circuits that it gives them the extra tiny bit of performance they need at the extreme benching they're doing. The reason for that is the same as the principles I described above.

 

If you want a more detailed explanation or "proof" of it, let me know and I can digress into a lengthy discussion about it. Otherwise, take the layman's explanation I just gave and order yourself 2x4 GB of high performance RAM and know that you've got a faster system than if you go with 16 GB.

If the main criterion for your motherboard choice is overclocking then the most important feature you can look at is the reliability of the VRM circuitry. Voltage (and current) regulation will make a significant difference in how high you can take a clock and remain stable. "Cheap" motherboards typically have poor VRM, perform just fine at stock speeds, but will be unstable at even moderate overclocks. The relatively high end boards or mid-range boards from reputable manufacturers will do well at mild to even high overclocks and the top of the line enthusiast or extreme boards are usually only worth the extra money if you get lucky on a CPU that can take full advantage of their performance.

 

Both the Deluxe and the Pro are good boards.

 

 

This thread, http://www.overclock.net/t/916189/official-intel-p67-z68-motherboard-comparison-list-oc-results , will give you a better idea of what the detailed differences are between the Deluxe and Pro.

 

A link to the spreadsheet is here: https://spreadsheets.google.com/pub?key=0AoXai57oo6AGdHJNSXNXVUNqbHZoTlZjblV2cVJUTlE&w=291&h=2175

 

The deluxe is the better of the two boards for overclocking and is priced accordingly.

 

Both boards are single PCIe x16 or dual SLI PCIe x8. The pro has one additional standard PCI slot (not PCIe or PCIe x4). The pro has HDMI/VGA/DVI out and the deluxe does not. The deluxe has 2 extra SATA 6.0 Gb ports for a total of 4 (the 2 extra are from the Marvell controller) and also has 2 LAN ports, whereas the pro has only 2 SATA 6.0 Gbs ports and 1 LAN port.

 

The Deluxe has 2 USB 3.0 and 8 USB 2.0 and the Pro has 3 USB 3.0 and 6 USB 2.0

 

The deluxe has 16 phase VRM and the Pro has 12 Phase VRM and that's where the deluxe is truly superior to the pro.
