Amen to that Brother. Glory to the Highest: Luke 2. Wishing everyone the best and many Blessings to you all.

The nice thing about Linux being open source is that it can be heavily scrutinized. With so many different flavors, the freedom to keep it pure is a luxury we're fortunate to have. Let's hope that this keeps the popular distros in check. There definitely are loonies that exist in the Linux world, but m$ is PC alcatraz in comparison.

What we need is an open source Windows. Now that would be Awesome. The best that we can do is to use the available tools to de-sin m$'s junk (iso) as much as possible, use apps to block what we can, and to use good overall computing practices.

Edit: Wow 7000th?

 

SuperPI - 1M

Getting 4.6GHz dialed in...steadily and surely....

 

Merry Christmas. I hope that all of you are having an amazing Christmas with your loved ones, and I pray that 2020 is filled with blessings, spiritual and financial prosperity for each of you.

Here are a couple of runs for old times sake. Not my best, but still pretty good. Humidity is a bit high today, so I can't keep going. Plus, family just arrived so I will be spending time with them. Have a great day, everyone.

@JoeT44 - haven't heard from you much lately. I hope you're doing well.




Too sweaty today due to abnormally high humidity (41% instead of the usual 5-10%).

 

No bad news (so far) to report on the latest EVGA X299 Dark v1.20 firmware update.

 

That's good news. I was curious about the latest bios and the questions surrounding that. Thanks for testing.

 

No problem. Having a triple BIOS makes the testing a little less intimidating. Looks like I can run lower voltage with v1.20 BIOS (which seems a bit odd) and the wPrime 32m and Cinebench results are still impressive. Perhaps because X299 does not support SGX and the Plundervolt exploit isn't a thing.

This score was slightly better with the new BIOS than the previously posted score using the XOC v4 BIOS and I wasn't even using chilled water on the run below.

 

Here's a CBR20 with the v1.20 BIOS at 5.0GHz. (My best score is 10895 at 5.2GHz.) Seems OK. I did fire the chiller up, but it didn't improve the score because it wasn't get hot enough to thermal throttle without the chiller at 5.0GHz.

 

Very interesting indeed.

Nice! I'm glad you'll be getting the 7980XE soon... It'd be great to geek out about the chip and benching.

I'm tuning the 3970x at the moment. Finally got 46x to pass a fire strike run! Progress..

 

I just came close to my best Time Spy run at 5.2GHz (with my best at 5.3GHz). My 5.2GHz is also using significantly less voltage now. Really weird and not sure how/why that can be. The graphics score was actually higher and my best Time Spy edged it out by a narrow margin due to a higher physics score.
Current with CPU @ 5.2GHz

Best with CPU @ 5.3GHz

 

I just beat my best submission on wPrime 1024M... (but, still not quite as good as my best 32M run with a score of 1.290 sec).

Great STUFF! .. That's on the latest bios eh?

Wow congrats! That's awesome Brother... Keep going!

 

Yes, it is. I'm shocked to be honest.

Just took first place on HWBOT in Cinebench R20 for 7960X.

https://hwbot.org/submission/431229...20_core_i9_7960x_10899_marks?recalculate=true

 

Fantastic! Cheers to that! I'm so wired on caffeine and benching right now. I had a feeling you'd top your PR shortly...

Good job! Congrats...

Nice @Papusan! . Previous hardware reaching new heights is often more impressive than the newer offerings.

 

Yeah, we can still have fun with the old.
But it could be much better if this old lady had working, MB, cooling and more than a single ram stick The MB is flaky and have problem with posting. Most likely at the end of life.

Replying to my own post due to update.....

Seems like I can get 3GB/s sequential write on CrystalDiskMark on the largest 32GB file size....as long as I leave enough/loads of idle time, so not only has the heatsink improved reads it's also improved writes - I never saw it this high before without the heatsink in the 32GB file size test...as long as I leave it idle for long enough. So that previous test result in my post I'm quoting wasn't just a one off blip, it's a combination of lower temperatures due to the heatsink combined with ensuring extended idle time before running the test. NVMe heatsink was definitely worth installing then.

 

That heat sink really made a big difference. Nice job, bro.

 

Hmm. Linux seems a little bit buggy on this new BIOS. Cinebench also seems to run a little slower on Linux than it did before.

 

My new toy




I know somebody who will like the bellow pic

 

Nice CPU and score. Nice UPS as well. What brand and model number is it?

 

I told you I have an APC 1500S graded for 950W unfortunately my current system is pulling more a lot more - I will buy a new one (probably a cyberpower 1850W / 2200 VA ex on Amazon for about 400$)

I will need your help/advice sometime soon (Jan maybe) for a chiller ...

 

Oh interesting hmm... have you tried rolling back the Linux Kernel?

Very nice Bro!

Ah yes! I know how that feels lol...I have a UPS back up rated at 900W and it's always beeping at me haha... It's definitely a time for server grade stuff to support 1000W+ ...

 

PiFast Bench:

Shipped back my Asus Zenith II Extreme mobo today and with that, I have no operational overclocking desktop rig. All five are in some stage of disassembly. I'm debating if I'm going make all of my loops modular with quick disconnects. It will make usage of my MO-RA radiators with all of my rigs much easier but I will need to add additional pumps to each loop to make up the loss of pressure. A lot to think about. In the meantime, I'll continue to watch you guys bench.

 

Do it, bro. The QDC fittings are the bomb. To bypass my radiators and run straight from the chiller I only have to disconnect the return line from the output side of the system and connect it to the output of the third pump and then I have the loop going chiller > CPU > GPU > chiller and all three pumps are pushing the water. To put it back is simple. I also have QDCs placed in a position that allow me to remove the chiller completely and still have the system fully functional if I need to (i.e. for maintenance or moving the system, etc.). No fuss, no muss. And, making these cooling system configuration changes takes all of about 20 seconds.

 

Just remember, unless something has changed, Koolance QD4 have the lowest resistance, followed by the EK QDs. But you either have to step down the QD4 to G1/4 or have to use some large tubing. EKQD is much simpler, but over 1.5GPM they can be closer to double the resistance of the QD4. So make sure which is best for your needs (and whether or not you are buying new fittings for the entire loop, etc.).

I'm considering QD4 myself in my loop. For step downs, it would be about $200-250 for the loop with QDs between each major component. Add an extra $60-100 if I'm changing the other fittings to accommodate a thicker hose. I already have two DDC pumps from swiftech in the loop, and before the QDs a single pump has the head pressure to do my CPU, GPU, and 3x480mm rads, so not too concerned with head pressure. Might also get one extra pair of QDs for filling and draining outside the system, which allows for each component to be quickly switched in without having to do bleed and fills in the system as much.

 

So, give me some hints and tips on chillers. I see they rate them in wattage. What wattage, and what chiller are you running @Mr. Fox ?

 

Yeah, that is definitely the way to do it. I can remove my CPU water block or GPU for maintenance without having to drain or refill anything at all. The lines stay full, too. So, it makes life super easy. I arranged the QDCs in an orientation that allows easy changes in coolant path (as mentioned above). I have an inline Swiftec D5 at the chiller, then the two XPSC Photon D5 pump/res combos positioned before the CPU and after the GPU (sort of a push/pull). I can pull the GPU and install an air-cooled GPU in its place by simply unplugging the CPU out line from the GPU in line and connecting the hose to the second pump inlet hose.

 

This one... https://www.performance-pcs.com/wat...tt-cooling-capacity-waterchiller-hc-500a.html

That is just barely enough chiller. I would not recommend going smaller. There is no such thing as too much chiller. You want the best you can afford to get the water as cold as possible.

If you get one that is too weak it won't get the water cold enough. And, you need to build the loop in a manner like I did to bypass the radiators by simply plugging and unplugging hoses on the fly.

If you run the chilled water through the radiators it will not get cold enough for higher CPU and GPU clock speeds. It will be much colder than ambient, but nowhere close to 0°C if the radiators are in the loop. When I am not chilling the water I merely unplug the chiller from the power strip and let the water flow through it.

I ended up having to buy more QDC fittings as I re-thought my setup. I have a total of 6 QDC connection points now.

 

That was the exact model I was looking at over at PPCS. Not really sure what gains could be made with Ryzen, but it would be fun though.

 

You'll need it for better Ryzen overclocking, and it will help a ton with your GPU overclocking as well. Honestly, unless you are going to go through the expense and massive hassle to do LN2, using a water chiller is kind of a no-brainer if you love overclocking. You can do so much more than you can with ordinary water cooling. I'd love to play with LN2 some day, but after watching all of the videos I can see where it's a major amount of work to set up and take down and it can easily turn into a massively time-consuming project for a few hours of fun. I'd much rather move just one hose, plug in one electrical cord and *boom* I ready to rumble.

If you decide the pull the trigger, let me know if you want me to make a quick video showing how everything is routed and where I have the fittings placed to make everything super easy and modular for instant on-the-fly changes to the loop configuration.

Edit: If your work space is large enough, buy lots of tubing so you can have a longer stretch of space between the chiller and your PC. The chiller puts out hot air just like an AC unit does and you would likely prefer to not have that blowing directly on you or your computer. I can heat my office in the winter using the chiller... seriously. It will make my office like 80-85°F if I close the door.

 

Check out aquatuning.us for the same type of chiller, but in larger sizes. The largest is a 2HP, 3300W cooling capacity beast for $1365 plus shipping. But just another place to compare pricing.

 

This just finished processing. It took forever since I did it in 4K to help make the text readable at lower scaling after YouTube butchers the quality.
Should be helpful to aspiring young gamers and overclockers. Feel free to share the link with anyone you think might benefit.

 

I second that video. Shoot a video showing what you have, how and why you did it the way you did. That would be perfect for a lot of people. Also, you (and others) can always refer to it when someone asks about your chiller.

 

OK then. I'll do it. Maybe even this weekend.

 

How ironic... I'm just about to crack mine open as it's still new in the box... really curious now given that it was burning oil on you ... hmmm..

Yea I definitely hear you Bro. Right now I'm juggling between the Z390 Dark, X299 Dark and the TRX40 set up..let alone the main gaming desktop. I almost want to run my Z390 Dark as a daily, since it's such a great board that actually performs... for now I think I'll finish up with the 3970x and to be honest I'm already getting bored of it and find myself wanting to hurry back to my 7980XE.

They are very convenient indeed and having more pumps like you have is very ideal... great stuff.

I have the QD4's, just not installed yet on the main test bench as I was waiting for my additional pumps before installing them... Are the specs for the QD4's around 3.0GPM exactly or more? That's very interesting as I was in search for the least restrictive QD's...

Very nice and practical set up.. that's definitely the way to go. For your xpsc d5 pump/res combo's is it just the base pump or do you have an actual reservoir on those too? I assume it's just the base pump with the tubing running in and out?

I agree... the loose rule of thumb ideally is to get 3x the chiller capacity (cooling potential/wattage) than the heat (watts) the system that is being cooled..., but the 500A is sufficient and does pretty well as that is the one that I use as well.

It'll do wonders for your 3900x brother... It does great for my Threadripper.

100%. A lot of us actually use our hardware for what it is intended for, therefore, going LN2 leaves us a lot more to lose than someone that is just using it for benching. All the power to the XOC'ers, but dang without any sponsorships to cut into the cost of the hardware, it's really hard to justify putting our hardware at risk lol... this is why like you've said Brother the chiller is the best middle grounds. It really is the best of both Worlds.

This also brings me to re-emphasize the importance of recognizing the different classes. When people see big numbers on the boards, it took LN2/DICE etc...to get there. Very cool for its class, pun intended lol... but at the same time big numbers in a different class is just as impressive. My respect for the top score in LN2 class is the same as someone on Air to reach a top score in their class.

You're right about the heat output lol... it can definitely warm up the room that it's in. At least the spent fuel (wattage) isn't going to waste ... well during the cold seasons that is.

 

@iunlock - are you talking about their high pressure variant? Koolance has high and low pressure variants. Almost all home systems would use low pressure variants as the chance of pushing up to 142PSI is low outside of more of a data center doing water cooling, even if the rack is cooled just to make sure cool air is blown through the rack (one way water was used without having it cool components directly in the service space). The low pressure is 7PSI, which is closer to what blocks and other fittings are rated for. So usually the low pressure variant is fine, unless you are putting plumbing throughout your house with QDs in the wall to connect the systems to with a remote chiller and a more industrial pump. But few here would consider such things and even fewer would need such a setup if any (think of copper pipes and running that to a server room with either the radiator or refrigeration unit remote so that sound doesn't get too loud, using QD bulk head fittings in the wall to connect to a distributed pipe running up the rack on one side and down on the other with regular intervals of QDs to then connect the system in the rack to incoming water and outgoing on the other side (so no confusion which side is in or out on your water flow on your rack).

You may still need local pumps to maintain flow, especially since what I just described is a parallel flow system, meaning as the flow is split to more systems, it will split the pressure pushed until recombined on the other side, not too mention drop across the system, etc.

But I got side tracked. Generally, low pressure is fine and most systems only use 1-1.5GPM flow rate. 3GPM or higher is really high and starts getting to high pressure systems. 1.5-2.5 is considered a fast flow rate, and from what I've seen so far isn't a pressure issue situation yet.

So the question is, what are you building?

Also, if really taking your monitoring up a notch, you can put flow rate monitors that feed back actual flow rate, not just the spinners, right before each pump in your system. If you have PWM pumps, you can then adjust each pumps speed to try to create a consistent flow rate at the end of each section of components so that the end result is a steady water pressure entering each pump in your system.

For mine, for example, that is one pump doing the CPU, GPU, and MB VRM. The other is doing 3x480s. So that would be to change each pumps curves for variance in what each section restricts to keep water flow at rough consistency in the loop. But that is also just me nerding out and is in no way necessary.

 

Thank you. I had to reconfigure it a couple of times to figure out the ideal line routing for the easiest way to bypass the radiators, or remove the chiller, by only moving one hose. I ordered more tubing yesterday so I could redo it and clean everything. The tubing is starting to look a little bit cloudy. It has been about 2 years since I flushed it. I just cleaned all of the fans and radiator fins today. The radiator fins were clogged up a lot worse than I had imagined. Didn't look too bad until I removed the fans to clean the blades and I was like O-M-G when I saw how much crud was in the radiator fins. I will probably completely disassemble it for a thorough internal cleaning and flushing in a couple of weeks. I will disassemble the CPU water block again to make sure the fins inside of it don't have gunk stuck in them like they did the last time I checked when I was running the 8700K.

I have the big D5 Photon reservoirs. The only pump with no reservoir is the Swiftec D5 mounted on the side of the chiller. The more water the system can hold the better.

 

OK, here's the video showing how I routed the chiller lines.

 

Why do the radiators need to be separated from the loop? Seems to me that the water would be cooler so the chiller would not have to work as hard?

I just checked HWBot for some CB15 scores using the 3900x, and the top score using chilled water was set at 4707 mhz. I was benching cb15 @4500mhz with my loop. If there was a chance of reaching 5ghz, I may purchase one, but for only ~200mhz, it wouldnt be worth it IMO.
https://hwbot.org/submission/4255766_i.nfrar.ed_cinebench___r15_ryzen_9_3900x_3744_cb/

 

Nope, exactly the opposite is true. The radiators actually work against the chiller and warm the water. Using the chiller with the radiators works fine other than the water not getting as cold as it does without the radiators. Without the radiators the water will get down to near 0°C, sometimes even below 0°C if the room is cold. With the radiators in the loop the water never gets colder than about 18-20°C idling with the fans turned off as long as the room is cold. With the fans turned on, it won't get colder any than about 24-28°C while idling. Under load the temps go higher. If the room is warmer the idle temps and load temps are higher.

If you think about how radiators work, this makes sense. The goal of a radiator is to try to make the water temperature normalize with the ambient temperature.

 

Think bigger picture. The chiller is a durable product that should last you a long time and it is system agnostic. Owning it wouldn't be only for your 3900X unless your current system is going to be your last one. It's expensive, but if you can use it for many years on many systems, it's not a huge investment. It won't become obsolete in 6 to 12 months. Also, don't forget your GPU overclocking will improve greatly. Probably even more than the 3900X overclocking will improve.

 

Ya true, radiators function to return the water temp close to ambient. After all you are just blowing room temperature air through them. Unless of course you move your rig outside in the winter.

 

Now you're talking. That would be almost as good as LN2 if you live in a really cold place. And, you'd have to use anti-freeze in the loop.

 

All depends on the silicon lottery. But 5.0GHz on AMD chips is a hard task

 

Thanks for the detailed reply. I was referring to the regular QD4's and was curious if the rating on those were around 3.0GPM compared to the previous QD3's? Like you've said the lower pressure rated at 1-1.5GPM is more than sufficient ...especially considering that the D5/DDC pumps aren't high pressure units anyway... It's always fun geeking out about the technical side of things.

Great set up and I love the fans over the RAM sticks.

Nice vid..thanks for taking the time to do this...

@Raiderman that's be awesome to get 47x on your 3900x...gosh it'd be nice to get that with my 3970x..maybe if I disable some cores and tune it some, however, the chiller does have its limitations after all as with all cooling...

@Mr. Fox it's a great investment indeed... likely one of the most ideal ones outside of the core hardware components of a system due to the fact that it allows the very core components to run at its best.

We'll have to bring our bench set ups and visit @Papusan.

 

I seem to have found a little bit of a sweet spot. Voltage is a little high, and the load temps arent the greatest, but it is CB stable. This thing loves Wprime 32, smoking some dry ice guys. Funny thing is the benchmate WR is by me, and is a better score than this one. 1.855. Granted there are only 3 submissions....lol
https://hwbot.org/submission/4314330_

I think I have cold enough temps. I could probably close the office door, open the windows, and set a fan in the window. If my wife will let me, that is.

 

Man... that humidity. That has to feel colder than 31°F with 75% humidity.

I thought it was too humid here at 45% (it's normally like in the 30s or less). I guess I shouldn't complain about 45%, LOL.

 

A little weekend fun with an m-itx board...

It's what I call a true console lol...forget the ultra low 30fps game consoles haha.
