@bogmali I was very sad I couldn't use my promiltech megahelem with my 3900x. I purchased a scythe mugen Rev b because it appeared to be the cheapest 8 heatpipe cooler I could find. With the stock fan I am getting at most 68c at full load for hours. I plan to install two better fans eventually which should improve temps further. This might be worth going back to full watercooling.

might have to break out Noc D14 sitting somewhere and hope that I have an AM4 bracket for it

Won't they send you one for free?

I don't think I bought that retail so idk.....will check their site.

Ahem

As you can see from my screenie, mine peaks at around 85C...might have to break out Noc D14 sitting somewhere and hope that I have an AM4 bracket for it

Congratulations. 25k PPD on what seems to be complete stock settings and Windows. That brings hope to my 35k PPD Linux dreams. You seem to be maxed out on all parameters, the D14 will help of course but the power delivery.....I'm a Ryzen Master noob (donwloaded it, and that's it) so settings might play in. What MB are you using?

What MB are you using?

Gigabyte X570 AORUS Pro WiFi Review

Another X570 board has entered the ring. The Gigabyte X570 AORUS Pro WiFi features WiFi 6 support, a sophisticated 14 phase VRM, and a classy refined aesthetic. Does it have what it takes to compete at its $270 price point?

Again I never tried Ryzen Master but that MB shouldn't be the limiting factor in your clock-speed. Now It (your settings?) and the stock cooler share that honor. Are you up to date with chip-set drivers, Windows updates and BIOS? Even my 2700Xs running Linux and not OC'ed are close to your chip. Anyway 25K and Windows is good so if you don't bother I understand.

I'm running it stock and don't intend to OC since just like you, I'm a noob to AMD overclocking. I have yet to update the chipset but intend to once I'm done swapping HSF.

I doubt that a real OC will do you any good, just let AMDs own magic do that job but drivers/bios seems to make a difference. HSF - I got two identical systems bar cases (test bench vs cases). The colder running chip (in a case, both below 70 C) is slower....so don't expect 0.4 GHz by cooling alone Keep us updated.

Edit: I had a look at you first post again and noticed your 4 GHz is as good as my 4.4 GHz on my 4970K - same MCM completion time and that add up nicely to 24.5k PPD.

With everything I have read so far it appears that you actually get less performance by overclocking. AMDs PBO can and will overclock higher if your motherboard can supply the voltage and the chip can be kept cool enough. Supposedly if you keep the chip below 50c it keeps some really high clocks. I am thinking about setting up a full watercooling loop just to take ADVANTAGE PBO.

My 480 mm radiator is waiting to be put in use....
Edit: Yes you need a serious OC to beat PBO and with power in the 99% range that is not going to happen.

I just rest mine on top of the CPUs, I don't connect them up at all... My 1700X's are normally pretty cool but this heat is making them hit the 75 to 80C under 100% load....

I pretend that I didn't read that .
I finally found a 3900X under Linux HERE. I can't make out if the user has optimized output (Zika) but it seems like it was slotted into an older MB, not that I don't think that the later would make any big difference. +35K PPD, yes I know a new CPU gets nice points the first 5-7 days. I got 30K on mine when Zika returned a week ago. I still think that it will beat what it replaces by a factor 5 at the same energy uptake (W3670).

The no-good place where I ordered my 3900X wrote yesterday and asked if I was still interested, come on the rig has been ready for two weeks now and I wrote them twice to ask for progress on their side. They are hard to find in Europe!

 

[phill]

It's fine mate Even with children running about, they know to not go into my PC room, so nothing gets moved Besides, I'm sure it would shut down or at least throttle if something happened to it

I've had a check on a few places I'd buy from by can't see anything in stock for the 3900X.. It does seem to be out of stock everywhere... Scan, Overclockers, Ebuyer.. Although overclockers seem to want £30 more for it.... Go figure...

 

[bogmali]

Had to turn off my 3900X since I couldn't find an AM4 bracket for either my Noctua D-14 or Cryorig R1. I would have preferred Cryorig's because of RAM clearance issues but unfortunately their AM4 upgrade kit won't be available for another 2 weeks. I have the Noctua kit coming today so I'll use that in the meantime.

 

[thebluebumblebee]

I wouldn't hold my breath on that Cryorig part:

I saw that as soon as I got done talking to one of OutletPC's rep explaining the situation

I find mine works perfectly without any mountings on it, just install it on the flat (motherboard flat) and it'll be as happy as larry
I don't use a case for my crunchers, but the 25mm stand offs prove brilliant when there's a bit of a gap behind the back of the board, just keeps the temps just right

When/if I ever get my 3900X I would take the @bogmali way and take care of it mostly because the difficulty to get it. As I understand a Noctua with the right mounting kit with the front fan off-set a bit is about to get into action. Phill don't tech the kids with their hard earned money your laid back approach to hardware

I do look after my hardware but with the 4 systems that are currently like this, they have been completely stable and without any faults However I do think the D14 isn't such a great performer as the Phantek's cooler I have, same motherboard, CPU, RAM and everything else but the cooler it seems to be about 2 to 4C higher under load... When they go in cases I'll mount them properly but until then, they'll be fine They sit still and don't move unless I move them I'm very impressed with the setups

 

[theonedub]

Here is the new setups inaugural WUs- core temps seem to level off at 55-57C with VRM temps approaching 70C. I think I will reconfigure one of the fans with a plastic diverter to help cool off the VRM with 24/7 usage. I think the temps could be better with this loop but it isn't horrible with PBO driving to 3.4ghz- not sure though.

Congratulations. I would do the same for sustained usage. I can see that you got the CPU covered.

That is really really making me jelly so kudos to you! I see you are going full force too. I really need to get something besides stock coolers for my crunchers. My Ryzen 2700X levels off at around 70C at full force.

Yesterday:
Opinion please. CL currently has 2 x 16 GB DDR4-2133 kits for $80! G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000) Desktop Memory Model F4-2133C15D-16GVR I've been wanting to purchase DDR4-3200, but this is basically half price.

So, the question is, (EDIT: Ryzen systems) will slower RAM have any real noticeable impact on crunching? Even w1zzard's testing is inconclusive.

Of course, Newegg dropped the price on the RAM that matches my X370 XPOWER GAMING TITANIUM, but only to $72 (only)
Today:
CL has these for $110: G.SKILL Ripjaws 4 Series 32GB (4 x 8GB) 288-Pin DDR4 SDRAM DDR4 2400

I did see a slowing down on my 4970K that doesn't like XMP so I have to set RAM speed to the rated number if the power have been off. The first time (some years back) I noticed a fairly big hit in MCM run-time. 2400 down to 2133 MHz I think, CPU clock wasn't affected. I can't give your precise numbers but now I pay attention to enter the BIOS at start up if I have a power cut/re-location of the rig. It's your 3770K right? Go for the faster set.

Edit: I will test a bit tomorrow, mayby only timings.

 

[thebluebumblebee]

It's your 3770K right?

No, they'd be split between my 2 Ryzen rigs.
