Awesome! Hope to win!

I have the Maximus VII Hero and it is a fantastic board for overclocking. You don't need anything more unless you are going for an OC record or something. The Hero looks great, performs great, and overclocking is downright easy these days, but the ASUS UEFI makes it even easier. My two cents.

Wow! 5Ghz! What voltage it it take to get that? I set my limit for overclocking at 1.3v because, from what I have read at least, it is the max voltage you should use for long term use. What is your opinion on that voltage and processor degradation? Also, Devils Canyon TIM seems to be a big improvement over original Haswell TIM. Anandtech did a comparison and Devils Canyon is as much as 16C cooler than Haswell. For $300 they definitely should be using solder though. Thanks.

It is all out of the box. No modifications made to the chip itself.

i7-4790k Overclocking Motherboard: Asus Maximus VII Hero Cooling: H100i My predefined limits. Voltage Limit: 1.3v Temp Limit: 80C Whichever comes first. No BCLK Adjustments. I didn't want to fiddle with anything but the multiplier and voltage. All adjustments made in BIOS. Voltage in manual mode and changed to adaptive mode after stable overclock is reached and tested. Must pass all tests to be stable. Final stress test is 1 hour of Aida64 - There is no reason to torture your CPU for 72 hours with Prime95. It is a super unrealistic workload and is not even validated for Haswell CPU's. I read that you could damage your CPU by doing this.

I was able to achieve 0.1v less than the stock turbo voltage, which is surprising. If you were just trying to under-volt, you could achieve about 10C lower temperatures at stock turbo with 1.150v if your chip is decent. Intel was very conservative with their stock voltages it seems. I made a graph of my voltages and you can sort of extrapolate to see what the voltage for a certain multiplier might be. Multiplier is X-axis, CPU voltage is Y-axis. https://www.desmos.com/calculator/jjgnmdh6ew

Hi all, after installing my H100i, I noticed something terrible. One of the fans has an annoying rattle at low RPM. It is not terribly loud, but definitely noticeable, and the fans are just loud in general which is just stupid for spending $100 on an AIO. I am running it with an i7-4790k OC'd to 4.7Ghz at 1.291v. It stays around 75-80C with that overclock while stress testing. I am looking for some fans that are much quieter than the stock fans, but still perform well, look good, and have good static pressure. The only caveat is that I really don't want cream white and diarrhea brown in my system because my theme is red and black. The fans must be PWM also. Some fans that I have seen held in high regard: Scythe Gentle Typhoon AP-15's - I am looking heavily at these because everywhere I look people praise them. Corsair SP120 High Performance - Looking at because of the color rings and PWM. Noctua NF-F12 industrialPPC - It's going to take a lot to convince me to spend $50 on fans. Any help and insight you have is welcome!

I set the voltage to manual 1.250v and 4.4Ghz. I was beginning the overclocking process as per Linus' Devil's Canyon overclocking guide. I was working on that when I noticed these temps. I had just started overclocking because I just switched from AMD to Intel and got the chip. I am downloading that right now to see if it makes a difference. I also verified the temp spikes in OCCT. Thanks for the help guys!

Merry Christmas everyone! I was working on some stress testing with my H100i and there were a few things that I had questions about. Stock at idle I'm getting around 35C, and load with Aida64 with CPU, Cache, and FPU being stressed it averages about 65C. What concerns me is this. http://imgur.com/2LlpL24 There is as much as 10C difference every second on each core. One second it might be 58C then the next second it will spike up to 68C. The CPU however will stay quite constant, averaging about 65C and not spike too much. I have no idea why this is happening. My H100i is hooked up correctly. The pump is always at 100% and the fans are at their default fan curve. Is this normal? Thanks for the help!

Hello everyone, I am thinking about doing a platform change in my Cooler Master Storm Scout II case. I am going to be switching out my 2+ year old AMD-based CPU and MOBO and I will probably be upgrading my GPU as well. My planned upgrades are an i7-4790k, Asus Maximus VII Hero, and an ASUS GTX 970 Strix. My current cooling solution is a Hyper 212 Evo and 4 case fans. I currently have 2 120mm fans in the top, 1 140mm in the front, and 1 120mm in the back. I would like to upgrade the cpu cooler to an AIO liquid cooler to cut down on the noise my computer makes and also to allow better overclocking and cooler temps. The only problem is case compatibility. The h100i and nepton 240m will fit in the top with an external mounted radiator, but I really would prefer everything to be inside the case if possible, although if I can properly protect the external rad from dings, etc, I would be ok with it (a grille over it?). This leaves a few options, The h80i and h60 etc, and various products from cooler-master such as the nepton 120xl and others. Which AIO would be better for moderate overclocking, quiet operation, cool temps, and $100 USD or less? Thanks for the help!

I just got my Titanfall beta code today. I downloaded and installed it, but all the servers are down for bug fixing. Still happy I got one though!

Save us Google Fiber! This whole merger thing reminded me of this video, freaking hilarious.

I got the stock GTX 770 from best buy also, it is one heck of a card. Games are maxed out or nearly maxed out, CUDA accelerated video encoding is insanely fast, and 3D modeling is roughly 10x faster than CPU rendering. At $330 go for it.

^^^ yes, if your computer is stable at 1333mhz, there is almost no performance improvement to be had by jumping to 1600mhz anyway unless you are running an APU. If it ain't broke, don't fix it!

I am no expert, but you could try uninstalling the GPU drivers, then doing a custom installation->clean install. Hope it helps!

@ionbasa Thank you so much for providing information about the issues I have been having and helping me sort everything out. I have good news, it turns out that when I updated the BIOS, there are apparently bad voltage settings for this particular CPU on this BIOS. I searched online for the stock voltage for the FX-8350, and found it to be 1.375v. When I was stress testing and getting errors, I found that the voltage was around 1.28v, which was causing the CPU to provide bad data causing the GPU driver to crash. I have manually set the voltage on the CPU to 1.375v and set the chip at stock clocks (4.0GHz) and ran prime95 and all aida64 tests, and lo and behold, no errors! Thank you again for all your help and support!
