Ryzen 3950X, 3960X, 3970X Availability

As soon as I saw notarat's post I went to the website to see if returns showed up on the web but no such luck for me so far ...

Also I'm not one of the lucky guys that strolls into the MC and bingo finds some CPUs. I have some time off next week so I'll keep trying :-D

It moves enough that your chipset would cook without it. Dont knock the 30mm. Just because your skin cant register the air flow doesnt mean the chipset derives no benefit.

I'm just not sure who builds a 16 to 32 core monster rig and expects it to be absolutely silent.

It's like expecting your Prius to pull a 35 foot 5th wheel camper.

At 30mm and an expensive tr3 mobo a slimline passive cooler wouldn't be too much to ask...
You can passive or make silent almost anything. It's just a little more expensive.

After Xmas I could look at getting something machined that's passive for y'all if the heat load is known. Clearance is the issue though.. 15W?

In that case, man am I in trouble. :p

Selling computer parts for which you have already received a refund and an RMA Return Label...yeah that can appear to be credit card/mail fraud. Even if you planned to write a check to BestBuy for the original cost (So I have to return it.)

This entire debacle will already be discussed ad nauseam in my quarterly interview...I don't want to make it more complicated than it has to be, lol
 
On a tangientally-related subject...I wonder how many 480mm and 360mm radiators will fit in a TT Core WP200...

And how many pumps one would need to ensure adequate coolant flow

And how many gallons of DI Water I'd need...

See where I may be headed?

I have too much time to think. This is HALF of the Core Case with an Asus Hero VI mobo installed... Imagine if there were only Radiators and pumps

MCE hang fix in 5.5


"The AMD machine check exception (MCE) code fix for Linux has landed ahead of this weekend's anticipated 5.5-rc3 release. This AMD MCE fix allows for the AMD Ryzen Threadripper 3900 series processors introduced last month to boot the Linux kernel without hangs or other workarounds."

Ah, I didn't realize you had already received the refund. My bad.

Just because I am curious, can you give any hints about what it is you do?

That case is massive. So the question is two 360mm radiators and a distro g plate, or three 360mm radiators and a separate dedicated pump in the 011 dynamic xl for a 3970x and eventually two video cards.

I'd always go single loop. Multiple pumps if necessary to get the flow where it needs to be, but always single loop.

Speaking of flow.

This Heatkiller VI block must be much less restrictive than the EK Supremacy EVO it replaced.

Ever since this upgrade my flow rates have gone way up at the same pump settings.

I used to have ek for threadripper 1 and 2 and Xspc doubled or more my flow rate. The ek TR block was truly refined from a hunk of horseshit ore.

I haven't manually compiled a kernel since the 90's, so I have absolutely no frame of reference on that one.

How well does GCC take advantage of multiple cores?

You are right. I think I must have suppressed those memories :p Gebtoo DID involve a lot of compiling.

The package manager did it for you, but it still took a considerable amount of time.

I used Gentoo for a few years, but in the end I didn't notice any real performance or other advantages from the custom compiler flags, and something was always breaking, so I switched.

Compiling kernels specifically for the computer you are using them in is fun.

But then I've been using Linux for 23 years so lots of manual stuff is second nature.

30 seconds is probably about as fast as things get really since there is still a few parts of the build process that are single threaded due to the sequential nature of some things that need to be done. I always time bindeb build target. It's crazy how fast things are this generation.

Yeah, I haven't compiled a custom kernel in ages. Sometimes there aren't standalone modules for the hardware you need though, and the only way is to grab a bleeding edge upstream kernel. Ubuntu's mainline kernel archive has everything already compiled and neatly packaged in .deb files that will work for anything that uses the apt package manager.

You just compile the driver code as a module. I just haven't run into a situation that I can't lately. Used to have to add in ivtv drivers for PVR / Mythtv into the kernel but that time passed years ago. Nowadays it's my extraneous wireless NIC or other driver.

I'm guessing it won't be long until this gets backported into all of the current 4.15, 5.0 and 5.3 kernels Debian-based distributions are using.

That's one of the benefits of having annoying uncle Ubuntu around. They do a fair bit of "making it work" work.

I wonder what I am losing by having "mce=off" as a kernel flag. I'm not quite sure what that option actually does. I know it has somethig to do with machine check exceptions, but other than that...

At some point in the future I guess I'll have to disable it (probably by pressing E in grub) and seeing if it still boots.

My friends at work and I were talking about the CPU and why I decided to return it instead of just keeping it or selling it to one of them. I reminded them I work in a high confidence position. I cannot afford even the appearance of impropriety or I lose my job. (I'm not referring to a security clearance...this goes way beyond that...) :angelic:

I'd like to believe you would have done the same even if you were not in such a position. Honesty is more and more fleeting these days.

Machine check exception - your basically missing out on hardware checks on the cpu, ram, ect. that prevents data corruption.

Did you have the initial release of the EK TR block that Kyle deservedly ripped a new one, or did you hvae the second release that was improved?

I'm not going to take restrictiveness in isolation as a negative. Sometimes you can get better cooling by forcing waters through microfins, and that inherently will make a block more restrictive.

Assuming both are competent designs, and that th eEK block isn't more restrictive for stupid design reasons, but rather due to more fin surface area, comparing the two becomes a difficult differential equation:

On the one hand you have a more restrictive block which probably has tighter fins and thus more surface area contact resulting in more effective heat transfer, but on the flip side this results in lower flow, so the same water sits in the block longer and heats up more resulting in less effective cooling.

On the flip side you have a less restrictive block, with less surface area contact, being less effective at transferring heat to the water, but due to its lower restrictiveness it gets fresh, relatively cool water more quickly.

It is clear there is some balance to be found in the middle somewhere where you wind up with max heat transfer, but I haven't studied this enough to know where it is.

Thanks mang!

I dropped it off at the UPS Store today...glad to get the temptation out of my hands...was considering calling Best Buy and telling them to re-charge my card for the cost (so I could have TWO 3950X based systems) but that's just stupid....

I need to save up for a 3970X lol.

No I had the first iteration so no further discussion in my part is need on how bad it sucked hahaha

As far as blocks the best design is a very turbulent ingress and a very high flow low restriction egress

High flow isn't necessarily good either, you can get a boundary layer formation which results in stagnant coolant staying at the heat exchange surface and getting super heated or cooled and not moving so not exchanging heat properly. This can occur both in the block (hot) and in the radiator (cool).

You mean like kids putting high flow high speed drag race only cooling systems in their cars that overheat at stoplights?

In my car it's a matter of cooling that sucker at 9200 rpm without going the electric water pump and fan route. If theres stand still traffic on a hot day I'll just have to stop the engine.. No big deal. Not a daily driver.

Wow. Two loops? What is the usage scenario for that?

You are almost guaranteed to get better temps if you put all of your blocks and radiators in the same loop.

Unless this is a show build, because multiple loops with different colors DO look pretty cool.

I've never leak tested that long. I usually just do it overnight.
Click to expand...

Would have replied earlier but "someone" had to go into work today...go figure...

I've been wanting to do two loops for a while on a build but, with the absolute crap I've encountered...missing CPU, shitty fittings from TT, Rads not quite fitting, I've decided to go as simple with the build as I can in an effort to finish it up ASAP.

That means going from 2 pumps to 1, 1 loop, nowhere near the mods I wanted to do to the XL case...

And I'm still going to have to order probably $500 of replacement fittings with shipping that gets them here Saturday (If I'm lucky)

GRRRRR

4 banger eh

I'LL NEVER buy or build a 4 banger again. Had an sti over 640whp.

Next performance car is gonna be a mid engine vette.

I'll never mod any car again.

I do like something that from the factory has enough get up and go to safely merge on to the highway and pass, but my boyracer days are long gone.

From here on out its all stock all the time :p

I don't care if its flowmasters on a V8 or a fartcan on a four banger, it's all equally dumb to me these days :p

Cars are grocery getters and commuter vehicles, nothing else.

I absolutely agree. That is why I would get a nice fast car and leave it as is.

Lately I have been toying with the idea of a tesla model 3 performance awd. But I dont want to spend 70k after taxes right now on a car. Everything I own is paid for.

Totally with you, but I was looking at the Model S. I wanted something a little bigger, and I hate the minimalist interior of the Model 3 with no instrument cluster.

In the end, it was just too much money to justify though.

Yeah and you can get a much nicer gas or diesel vehicle with more features that have the same or less cost of ownership.

Not really - that's usually because they don't have any airflow when stationary - more like those that remove their thermostat altogether and have overheating problems instead of taking the plunger out and keeping the housing as an orifice so the flow rate stays as engineered.
 
ShopBLT has 4 3970X's in stock NOW. (There's a $50 mark-up but considering the MSRP, $50 isn't much of one)
