I have been runnin at 1.1v 24/7 no issue.

Haswell is so sick, this chip is way better than ivy. I dont know what people are talking about when they complain about haswell. Certainly way better than the FX-9590 (oc vs oc, nearly twice as strong per core... what a crappy chip, cant do 2400mhz+ or pci-e 3.0).3GHZ
BCLK 100.01 x 125BCLK Strap (for some reason. auto or manual 100bclk comes out to like 99.8 so 100.01 normalizes it to 100, on both x1 and x1.25 straps)
IMC/Digital/Analogue +.2/.2/.2 (set and forget)
Z87X-UD3H F6 Stable
Delid, H110 w/4x 140mm YL-H
125BCLK x 29.33 = 3GHZ
I set it to XMP profile (which sets much looser auto timings as you increase frequency than just no xmp), then:
CL13, all else auto (so 13-16-16-16)
I did leave it on CR1 though, i forgot to undo that lol.
Ii havent even begun loosening it more, this was first try, im sure i could tighten a lot of the timings too, maybe even cl12). I've actually verified that, my optimal CPU settings are email@example.comfirstname.lastname@example.org using h264 benchmark. Using 4.75ghz is hoping I can squeeze an extra 50mhz out, that'd be sweet.
I mean this is special right? Not much ram can do 3ghz, right? Or can all ram do it if you loosen all the way to CL13? The maxxmem scores are pretty absymal, hopefluly i can tighten it a bit and that changes, but maybe i drop it down a bit and tighten..
ure tRDRD and tWRWR looks pretty loose. cause those bandwidths are so low. should be doing 5.
h264 is not intensive. The intensity of prime is to test ure other voltages not vdimm. Vdimm is a dead giveaway.
Mine is always now linpack 11 followed by prime95 avx 27.9 blend custom change each fft length from 15mins to 1 hour and do full mem 14gb-15gb mycase for 8 hours. Its the large fft thats the hardest.
How can you tell what my rdrd and wrwr look like from the picture?
I can't find any way to see my more obscure timings (like to see if bios changes stuck), since MemTweakit doesn't appear to work like it did on z77x-ud5h. I'll try to run the bench again at 5 but I think it's because my main timings are so very loose, and I'm sure my auto timings on every secondary and tertiary timing also contributes to the weak score. I think for the best 24/7 overclock I should probably go with a slightly slower speed like 2800mhz with tighter timings. I'll play around in maxmem.
h264 benchmark, are you familiar with it? And streaming can be very intensive on medium or slow preset, but i was referring to h264 benchmark program. if you run 1 hour fft lengths, does that mean you run for... ~70-80 hours on prime95 blend to do each test?
No way man a average chip is 4.6 at 1.2v. This is above average, and not just a little. Stop listening to the reviewers or whoever said 4.6 at 1.2, 4.7 at 1.25 4.8 at 1.3 or otherwise you have a bad chip. I'm pretty sure Intel gave them the best of the best in term of overclocking because here on OCN people struggle to get past 4.5Ghz at a reasonable voltage. And I still haven't seen a 5GHz haswell running on air/water that passed P95 for hours or other stress test.
I think you are very confused? email@example.com stable is a very, very above average chip, an average chip will load into the OS at firstname.lastname@example.org. My chip won't boot at email@example.com, and requires ~1.3v for 4.6 to be stable. So yea... like I said, my chip is a very below average chip. I dont know what you are saying, you are saying something even more lenient than what I said and my chip is still worse than that. You must've misread my post or something.
People here on OCn struggle to get past 4.5 because they use cheap, budget, low end heatsinks like the Hyper 212 or H60 or even a D14 is really too weak for haswell, and they aren't delidding. In a few months, you'll see, the delid club will be full of results past 4.6ghz as people delid and use decent cooling. And I dont know what you mean, there are already tons of results of over 4.7ghz on Haswell for 24/7 overclocks. Most people use an i5-4670K and a hyper 212 and think all is gravvy, that's the problem.
P95, avx, has that weird overheating, or voltage issue, but there's a guy running single stage phase at 5.3ghz 24/7 overclock on haswell, Alatar, because with good cooling you can take haswell just as far as anything else. Now single stage is obviously a bit extreme, but once the custom water loop guys start delidding you'll see 5ghz (which was always just a dozen or so people on OCN on sandy and ivy too).
Just don't like them, i've seen too many closed loops break and destroy other parts with them and a custom loop requires too much hassle for my liking. An air cooler on the other hand is much more safer and faster to install. At least for my needs. 4.6 at acceptable temps is enough for me. If you want to overclock the hell out of the cpu then yeah, a custom loop is the way to go. But an air cooler is still not absurd, that's all i'm saying. You shouldn't call it absurd just because it does not suit your needs.
Custom loops have really come a far way, and Corsair will cover damage to any parts in your system if their loops leak. I think it's a bit ridiculous to say air cooling is safer to install, there's a chance you could drop it and stub your toe or bend pins. Ridiculous? Yea... just like the idea that closed loops are dangerous. it's no longer the days of the h40 or h70.
And air cooler is kinda asburd. it's a $300 premium chip. Why in the world would you only spend $40 on cooling the 1st/2nd most important component in your $1000-1500 rig? Like you spend $1500 on a computer, but only $40 on a heatsink, one of the most important parts? Silly. Just silly.
Air cooling doesn't fit anyone's
needs on haswell. If you are going to be stubborn and only use a weak air cooler on a chip known to consume a ton of power, then maybe you shouldn't be going around about how haswell is a poor overclocker or runs hot. Haswell runs just fine, the problem is people using inadequate gear. If you used a $20-40 PSU and it blew on your Haswell rig, you'd be laughed at, or your cheap motherboard, etc.
Before delidding, I was running the same OC 24/7 (4770k/4.6/1.28v) and getting a max of 86deg at load with the NH-D14. If I pushed my processor any higher, it would get over 90deg. Also, I am not using the 120mm fan on the cooler - not really necessary in the TJ08-E, with it on it made almost no difference. So you consider this performance to be mediocre, what air cooler would you choose that does better?
After delidding, it dropped by 20deg, I can now push my processor to 4.9/1.47v and it gets pretty much the same temps that it was getting at 4.6 lidded.
Personally, I'm very happy with the NH-D14.
Phanteks, Assassin/K2, maybe the Silver Arrow. Air cooling is really going to struggle to push moderate-high overclocks on haswell even with a delid and tons of case fans. Air struggled to keep a delidded ivy cool on high overclocks, now add the FIVR.
A big problem with the Nh-D14 is the stock fans are low-speed fans (1250RPM). You really need higher speed fans, but the noctua stock fans are also awful. They have non-existent static pressure and pretty poor cfm/dba. 3x140mm high speed fans would make a difference.
He may be referring to charts like this, where the D14 scores middle of the road compared to newer offerings such as the Thermalright Silver Arrow Extreme.
Yes. Nh-D14 is just the 2nd weakest high tier air cooler, ie dual tower, just ahead of the Frio Extreme (and cnps14x, if you count that too). It's old, and was never meant to be a high performance cooler, it was meant to be a quiet cooler with tons of space between fins and very little surface area relative to it's total area.
I'm sure you can do a moderate haswell overclock, like 4.4-4.6ghz, maybe even 4.7 (4.8?) with a great chip, but a high end closed loop (h100i, cm240m, h110/x60) or custom loop kit (eisbergs, xspc, h220) would really do a lot. For $40-50 commonly on ebay it's a great cooler if you are limited on a budget, but if you can afford a haswell system i think there's more appropriate cooling, at least a used/refurb h100 for $50-70.
