What about Crucial? There is always a chance that any of these brands would have a flacks stick. Over the years I have tried G.Skill, Corsair, OCZ, Patriot, Crucial, Kingmax, GeiL. I find that only 2 things matter: the actual memory powering the stick and actual user's overclocking results.

Yeah, there is a huge range with memory and overclocking. There are brands and models only rated for something like 1600 mhz but will easily OC to 2400 mhz and there are those rated for 2133 mhz but won't overclock at all. Then there is the individual variance within each model.

G.Skill 3000 ddr4

Have a look at the voltage, the memory controller is on CPU this means your overvolting the controller as well? am I correct? default voltage for ddr4 is 1.2v these run at 1.35v

Pretty much. Not sure what the tolerance is on memory voltage on Haswell-E.

As far as the 1.35v's go it's factory overclocked memory. Up the volts and up the clocks. A person could just downclock the speed and lower the voltage within spec I'd imagine.
 
Over on overclock.net several people are having issues running their memory at higher speeds on X99. Also some board manufactuers force you to raise BCLK to run the higher speeds, but others(Asus) have already put out BIOS updates that rectified that.

I ordered the 2666 Corsair Vengeance stuff for now. I plan to replace it down the road when the memory offerings improve. The Dominator Platinum DDR4 kits just make no sense right now, $600 for the same specs as $300 kits.

Just about done. Need to copy a bunch of stuff from my backup HDD to the 4TB Samsung EVO array before getting into overclocking and testing.

Now that we're talking about DDR4 memory: supposedly it's aimed at 1.2v. Yet all the pics I'm seeing have large RAM heatsinks. With DDR3 RAM, especially with the 1.35v DDR3, I was looking at low profile memory. And Samsung had some very low profile memory.

So here is the question: who is making low profile DDR4 RAM? With low profile RAM I can have an NH-D14 with two NF-P14's or two NF-A15's, instead of running the front fan at 120mm.
 
Still at stock settings. CPU and memory are at default. Decided to run LinX AVX again while Acronis does its thing restoring a backup to the SSD array (danger proposition, I know). All turned out well. Acronis just finished the restore and I got some temps. This is with 14 threads and 24GB of memory at the same time Acronis was restoring the backup. I was also browsing the web with Waterfox. Room temp was around 75° F.

Looks like the Thermaltake CLC is holdings its own at stock.

Will be interesting to see the overclocked numbers.

Is this the 450D case the build is in?
 
where did you download CoreTemp 1.0RC7? The newest on their site is RC6, and that version freezes / crashes Windows 8 / 8.1 pretty spectacularly.

I knew I should have spent the extra $10 for the Avexir Platinum 2400mhz kit. I ended up just getting the Crucial 2133mhz kit because I already was over budget. Who knows, it could OC well I guess, just a green PCB on an all black X99S SLI Plus.
 
I'm still messing with the DDR4 on my Gigabyte X99 UD5. No matter what, I cannot get over 2400. 2400 boots and runs LinX fine. Get it up a small bit to 2500 and it won't boot at all. I've tried all sorts of base clock and uncore multiplier values. Nothing helps. This happens even if I remove four DIMMs for 16GB instead of 8 DIMMs for 32GB of system memory.
 
I'm hoping a BIOS update on this UD5 will fix more than that. I cannot get into the BIOS at all if I have RAID enabled on SATA ports 0 to 5. It will hang at a black screen forever. Only a CMOS reset fixes it. I also somehow lost the ability to boot with Display Port connected to my top GTX Titan. Using a DVI cable now. I'm thinking of going with the ASRock X99 WS and returning this Gigabyte board to Micro Center. Gigabyte tries, but they need real enthusiast testing.
 
Gigabyte had a ton of bios problems that they carried on to their later models as well. Z77 and Z87 boards had the same fan curve issues where CPU Fan 2 would just stop spinning after a few minutes. Boot loops still occurred as well and USB ports would not work at boot thus making it impossible to enter the bios.
 
So... after the easy 4GHz I was on to my next adventure at 4.5GHz... and holy $#!^. At first I tried 1.30V with the test I did earlier and it locked up after 1 minute. I then set the CPU to 1.40V and my eyes bugged out once LinX was done allocating memory and began working.

Yes, there is a very apparent wall around 4.5GHz with the 5960X. Punching through it requires a lot of voltage and a lot of cooling. It is something I don't want to mess with.

Trying 4.3GHz now with just 1.25V and even lower memory timings. I'll see how it goes over night.

Could anybody tell me the difference in my 980 6 core and the new 5820K?

Would it be worth it? Perhaps 30% faster? Looking to upgrade but not sure if it would be worth it.

Thanks.
