Are there already results of an Nvidia Ampere?

I was lucky enough to get this direct from EVGA https://www.evga.com/products/product.aspx?pn=12G-P5-3968-KR.

Guessing it will do a much better job than my old heavily modified 2080ti..   Thanks for your advise Ian, cant wait to fire it up!

That will work quite nicely

That will work quite nicely being a hybrid card.  Will keep the clocks up at max boost all the time because of the the much lower temperatures compared to an air-cooled card.

I'll let you know. 

I modified my 2080ti Founders Edition with water cooling and it went from an over heating, throttling,  POS to the card it should have been when I bought it from Nvidia.  It never performed until I ripped off all of the Nvidia "Pretty stuff" and put a NZXT water cooler on it. Now under 100 percent load no temp is above 60c. (Thats Memory or GPU!)

I just want to add, at the prices these cards are being sold they should be able to run flat out for hours at a time without fear of over heating or performance degrading throttling.  (Yes I'm still sore that I had to void my warranty so I could make my card perform well enough to run BOINC projects, and play games without damaging it.)

That's why I have almost exclusively purchased EVGA Hybrid cards for over ten years.

When the summer comes to the

When the summer comes to the northern hemisphere, ...

I will have time to take a look at the GR == GammaRay version again.

It seems to have all (non fft) kernels having 256 threads, and an occasional sorting done with less threads. The official code says something like: #optimize #this and that "we should not have any reason to run with multiple workGroups..."

THERE!

That was in SETI code the main reason it was not performing as expected (Scaling) on the newer platforms.

A part of the code was designed to be run on a single SM of a GPU (that could have them from 16 to 72 and nowadays approaching or going over 100).

...

but it is a winter now and almost not time at all to spend near the computer, so ...

 

I wish the people that do have the  r e s p o n s i l i b i t y  of taking care of the code have some extra time to spend with optimization.

Looking forward to any of your wizardry in code tweaks next year then, Petri.

Happy Holidays!

Just wanted to report back. 

Just wanted to report back.  While I have a fair amount of tweaking yet to do (That includes installing a new power supply, 850 watt is right on the edge of not big enough...) I can safely say that the EVGA 3080TI hybrid solution is a BEAST!  I can also say that  I will never buy an air cooled card again.  The lower temps, and noise are worth the premium.   In fact, I'd be tempted to use an after market solution like the NZXT Kraken on a brand new air cooled card in the future, warranty be dammed!

I do see one thing that seems

I do see one thing that seems odd.  It appears that while the 3080ti card is burning through the tasks in approximately 4 minutes, the CPU portion of the task is now taking an additional 5 - 7 minutes.  I have cut down the number of CPU jobs that are running by setting max number of CPU's to 30% and Max CPU time to 100%.  CPU is only loading to 38% to 40% should have extra cores available.  Not sure whats taking so long... 

If anyone looking at my system specs can see something obvious that I need to configure for max performance please let me know.

the long wait time at the end

the long wait time at the end is normal for the gravity wave tasks that you are crunching. if you want to see some real speed, then disable gravitational wave tasks in your project preferences so that you only crunch the gamma ray tasks.

 

regarding your hybrid card. they work well, when they work. I know Keith has had several of his hybrid cards have the pump fail and need to send the card back to EVGA for a replacement. just keep an eye out for that.

personally I don't think the hybrid cards are suited for 24/7 use. the pumps they use are too cheap, but are fine for what they are designed for: intermittent use and gaming. I either use normal air cooling, or custom water cooling with reliable pumps or even redundant pumps.

I hadn't given any real consideration to the pump as I have never had any of my Liquid CPU coolers fail.  Of course my experience base is limited to 4 or 5 from only two different companies. (NZXT / Corsair) 

I was considering selling my 2080TI with the liquid cooling loop, but I may keep it instead as a backup and sell my 1080 card.  Thanks for the heads up!
