Description

I Started out with the intention of just taking the guts from an XPS 8900 (I7-6700K) and putting them in a new case and MOBO to allow the use of my H115i Pro and provide better overclocking ability. Interestingly, I originally built the computer with the XPS parts so all I bought was the MOBO, Case, and G.Skill memory (All for around $500) and had it up and running... Then my sister told me she needed a PC so I ended up buying the additional parts to allow me to put both computers back together. I was going to just buy another I7-6700K for Drogon but found the I7-7700K chips were a lot cheaper (not sure why). Essentially, the price for this build includes Drogon as well as putting my XPS 8900 back to stock.
I already had the EVGA 850 G3 power supply and MSI video card, but purchased the rest.

I have the 7700K OC'ed to 5Ghz currently with no issues. I will go for more at some point.

I neglected to take pictures during the build but included a couple of pictures of the case installed in my desk. Next time I pull the PC out of the desk, I will take pictures. Because it fits so tight, it is kind of a pain to remove it. There is still room at the top for radiator air flow, I have it exiting the case with the front fans providing intake. Runs about 5 degrees C higher in the desk than sitting on the floor.

On a side note, the Corsair Air 540 is a sweet tower with huge amounts of room. I will consider a custom loop in the future. One downside of the case is that you are limited to 280 mm rads and a second being no filter for the top mounted rads. There is room for XE size 280 rads in the front and probably the top as well with plenty of room for other cooling loop hardware. I should also state that the reason for choosing this case was its ability to house an ATX MOBO, my 280 AIO cooler, and still fit in the space shown in the pictures.

What's the Voltage. also, nice desk.

Thank you about the desk. Currently running Core Voltage @ 1.33 and VCCIO at 1.30. To be honest, I haven't done much tweaking to see if I could get the voltage lower. I looked at other peoples 7700K 5.0 GHz voltages and dialed them down .02v and it just worked so I left it be.

I also haven't started tweaking on the memory yet or run any intensive benchmarking like Prime95 to verify the overclock. I would like to see if the OC is stable at lower voltages for heat considerations. If you like, I will take screenshots of my current bios settings (the ones I tweaked) and post them.

Sure.

I posted images of the values that I changed. I changed VCCIO back to AUTO to see how the BIOS would control. So far voltages have been lower than my original 1.33V and still stable. Once I start tweaking more I will go back to manual.

Let me know if you have questions on what I changed.

Edit: I'm not sure why CPU temp shows as 45 degrees in BIOS, I am looking at it in both Corsair Link and AI Suite right now and it reads 37 and 30 respectively. Strange, maybe BIOS uses a different sensor in the chip?

I have been taking my time today instead of playing some games, and got my RAM pass 3000MHz finally. I never actually took the time to get it higher. I made it 3100 and went to 3200. 18-19-19-43 is the timing now. and latency is lower, I want to go higher if I can.

I have my Core 5GHz and Cache 5GHz at 1.340. My motherboard is a limiting factor tho :( I could push further.

You probably already know this but for general forum information, just having higher memory frequency at the cost of latency isn't always better. See these articles: Latency And CAS Latency 2. I'm Not saying higher frequency memory can't make a difference but if you have to really dial latency up to make the system stable, it can actually slow down the memory's overall performance. I am by no means an expert on memory overclocking but there are tons of articles and posts on other forums by people that I consider experts. My opinion, based on reading many of those posts and articles, successfully overclocking memory can be a lot more complicated than overclocking the CPU. Primary, secondary, tertiary timings and more. Here is a good post that shows the complexity of memory OC

Passmark or AIDA64 are good benchmarks to test ram performance while you overclock your SDRAM. Unigine benchmarks and Cinebench R15 are good graphics benchmarks to use when overclocking graphic cards. Prime95 is a great way to test system stability as you change overclock settings CPU and Memory

What Mobo do you have?

Where did the front 5.25 panel go?

I just hadn't reinstalled it yet. I was using that hole as a hand hold for moving the case into the desk.

is it getting enough air?

As long as the door is open then yes. Motherboard temp runs around 29 degrees C I am overclocked to 5 Ghz but at stock clock, the proc runs 29 degrees C

How's Windows 7 on the 7700K? Did you have to do some magic to get updates working again? (They purposely disabled updates to Skylake and up for Windows 7)

  • 15 months ago

Good question. On the second Windows install (performed due to AI suite not working) I turned off Auto updates right after a clean install. I then installed all of the drivers and hardware support software. Finally, I installed all windows updates manually EXCEPT the May 2018 update which is when the irritating pop-up message began on my other build. No message and I still get update messages and AI suite installed fine. Funny, the only issue I had was connecting my Bose QC 35 headphones through BT. Since I had the issue on my previous build, I had the fix already.

Nice OC. That’s a great voltage for 5ghz!

might want to consider poking a hole in the back of you're desk for ventilation

Good call, but there are already three 1.5 inch by 18 inch slots in the back of desk. They came with the desk for just such an occasion and to allow cable routing.

I have had the computer running for 20 hours at idle. It runs cool. Mobo temp has not been higher than 27 C on this run, CPU temperature has not been above 35 degrees and has averaged around 30 degrees. H115i Pro water temp is stable at 27.5 degrees.

Correction on this post, the slots are 1.5 inch by 15 inch (wrong key)

I did seem to get a good chip but I have seen a few people get as high as 5.2GHz on closed loop cooling. OC Results I haven't really pushed it yet or tried to lower the voltage. I got to a stable 5.1 Ghz but backed it down to 5.0 Ghz for day to day use. I did a 2 hour run on Prime95 with no issues at 5.0.
At least one person got around 7GHz on Liquid Nitrogen

I have a Rockit 88 Delid tool and will delid at some point but I am happy with the chip so far.
