Funny thing, I can run 4.3 GHz on my 3700X at 1.325v all day long but trying to run it at 4.35 GHz doesn't seem doable even at 1.4v. I guess that's the nature of the silicon lottery.

I looked at the pricing on Mwave and it looks like it's selling for $499: https://www.mwave.com.au/product/lg-32gk650fb-315-144hz-qhd-freesync-va-gaming-monitor-ac19554 I assume that's in AUD and not in USD?

Can you show a screen shot of your BIOS settings?

Well if you're running 64GB of RAM on a 3900X you're running 4x16GB sticks which will put a higher stress on the memory controller than running only 2 sticks so you're probably not gonna be getting the same type of speed or latency you can from running a 2x8GB kit or 2x16GB kit. So from that perspective yes you can decrease the performance in certain applications (though not by much) by not having the same speed on that RAM as can be achieved with only 2 sticks of RAM.

LG has a pretty decent 32" 1440p 144hz Freesync monitor (non-curved), the LG-32GK650F-B that currently sells for about $300 (if you can get one at Microcenter) or if not from $340 (from Buy Dig). I got one at Microcenter and I'm liking it so far. The colors are pretty good after a quick menu adjustment and the latency isn't bad either. I've tested the G-Sync capability and it works just fine after checking the box in nvidia control panel. Hardware Unbox also did a review on this monitor and they also gave it a thumbs up.

I'm using the Phanteks PCI-E Riser card (bought from Amazon) but I'm wasn't actually using the vertical mount bracket (the one that attaches to the PCI-E riser card) at the moment since I didn't have it when I built the loop (misplaced it somewhere but it does come with the Evolv X by default apparently). I have since gotten the mount (apparently Phanteks will sell you one if you e-mail their support). At the time I was just using a piece of foam under the card so that it would be at the proper height of the mounting bracket and it worked just fine. Yeah I turned up the fans and pump to 100% and also opened up all the panels on my case so it would run just like open-air and I was able to get the temps down by about 6-7 degrees compared to running everything at 60% with the case panels closed. I also hooked up a thermometer to get a better measure of the actual ambient temps in the room where my PC is (instead of what my thermostat shows) and it looks that that works out to be about 7-8 degrees delta between water and room temp. So it looks like the combination of lower fan speeds and the Evolv X not being the greatest case for airflow are contributing to higher temps. Still I'm fairly OK with max GPU temps that generally don't go above 50-51 C during gaming and I'm guessing moving to a better airflow optimized case would be a good idea in general. Still I love the look of my Evolv X and I think the temps are good enough.

I think most newer boards have this option now. My current Gigabyte board has it as well as the two previous ASUS boards I've owned.

You have to use the bios flashback feature: https://rog.asus.com/forum/showthread.php?1142-How-to-use-ASUS-ROG-USB-BIOS-Flashback

I have the fans spinning at 1200rpm usually (around 60%), at full blast (2000 rpm) they are way too loud. Also I thought about getting a hybrid 2080 Ti to go with the H115i Pro I had on my CPU but I've been using dual AIO setups for so long that I didn't want to deal with the noise/cable mess anymore. I guess should probably switch the case in the future as well since I don't think I'll be fitting 45/60mm rads at the front or top very easily inside the Evolv X. The top 30mm rad with a fan in pull is already getting close to the motherboard VRM heatsinks. BTW I have a fill port at the top which I've attached a piece of tubing that then attaches to the top of my rad. Would the fact that I have air inside this tube affect my loop at all? Would I be better off just removing it and closing the top of the res with a plug instead?

I have a 420mm rad in the front, and the top is a 280mm rad. They are 30mm thick rads (16 FPI according to Corsair). I guess in the future I should go with at least 45mm rads, but I was hoping that since I'm only running a single GPU, I would be ok with 30mm thick rads.

So I finally decided to venture into custom water cooling. I have the following parts: Case: Phanteks Evolv X CPU: Ryzen 3700X @ 4.3 GHz 1.35v GPU: EVGA RTX 2080 Ti Hydro Copper @ ~2115 MHz core, 8000 MHz memory Rads: Corsair XR5 280mm & 420mm Fans: 5xEK Vardar Evo 140mm @ 1200m (typically) on radiators, 1xCorsair ML140 Pro at rear of case Res/Pump: EK XRES-100 Revo D5 combo (~60% speed) Tubing: EK Duraclear 10/13mm Fittings: EK-ACF Blocks: EK-Velocity RGB, EVGA Hydro Copper block This is the first time I've set up a custom loop and after spending many hours bleeding and leak testing, the results I get aren't exactly the greatest. My CPU hits around 76 C on a sustained 30+ min Cinebench R20 loop which isn't too bad since I know for this type of CPU a custom loop doesn't make a huge difference vs an AIO. My GPU though hits 53C overclocked and my water temps are 30 C at idle and 41C full load. If I open up my case I get around 38C load on the water temps and my GPU drops down to 50-51C. My ambient temp is ~24-25C (as measured by my thermostat). I'm running the front 420mm rad as intake and the top 280mm rad as exhaust. I've read that for a custom loop like this I should be expecting a <10C delta on the water temps at load but I'm getting closer to 15-16C delta. Also I was hoping for the GPU to stay below 50C. I don't currently have a flow meter connected so I can't check the flow but it seems pretty decent when I was filling the loop. I'm fairly ok with the temps as is since it's the summer time and my ambient temp is higher than typical even with AC but I feel like the water temp/GPU temp could be lower. Are these temps about what I should be expecting or should they be better? Also suggestions as to improve temps/airflow would be appreciated as well. I've attached a picture of my loop as well.

I have to agree that 1.39 or 1.4v is way too high and you'll definitely start to run into heat issues. I was running my 4790K at 4.6GHz at 1.25v and I was perfectly happy with that result. Sure I probably could have pushed it to 4.7 or 4.8 by increasing the voltage to 1.3v+ but the gains from a 200 mhz bump is not worth the potential instability and extra heat IMO. Even at 4.6 GHz and 1.25v on a Corsair H110i GT with 4 fans in push-pull, I was still getting core temps from 65-70C on max load.

Just overclocked it to around 4.4-4.6 GHz and it'll be perfectly adequate for gaming and light productivity tasks. I used to run a mini-ITX system with an 3570K @ 4.4 GHz and a GTX 780 Ti and it ran pretty much all games just fine, especially if you're playing on higher resolutions. Also there is no reason to choose a Haswell proc right now over a Skylake proc as the pricing is basically the same (a quick look at Newegg and you'll see the 4690K is only $20 cheaper than the 6600K, which likely will change in a few months) and of course motherboard pricing is pretty similar as well. So unless you are buying used there is no reason to choose Haswell over Skylake especially given all the improvements that Z170 brings over Z97/87.

That's true and I definitely have no intention doing something like that anyway (would be way overkill for anything I'll be doing) but I still think the fact that this essentially limits your options to using the 3rd PCI-E slot for an Intel 750 SSD to be a little disappointing as simply relocating the M.2 slot at a different location would have fixed the issue. Yeah I kinda wish Asus would give us a release date and/or a price on the Maximus VIII Extreme as well as the Z170 WS. Though from previous releases the Maximus VIII-E will probably be a $400+ board while the Z170 WS will likely be the same price as the Deluxe (based on how the Z97-WS was priced the same as the Z97 Deluxe).

Personally I'm not a huge fan of mATX boards. Sure they usually offer a second PCI-E slot and two extra DIMM slots compared to most mini-ITX boards but the way that the vast majority of mATX boards are designed are not friendly to SLI. Even something like the Maximus VIII Gene (which is supposed to be optimized for gaming including SLI support) from Asus is not optimized for SLI since the two cards would basically have no space in-between for the top card to breathe properly. Also while an mATX board put inside an mATX chassis can end up being significantly smaller build, unless you need SLI or really need to have a second PCI-E slot for other devices you might as well go all the way to mini-ITX and get an even smaller build. If you're gonna be going with an ATX chassis anyway, it makes no sense to buy an mATX board unless you are trying to go absolutely as low-cost as possible.
