4 PCIE slots - use 1st & 4th

that board wont work in his HP.

I am aware of that, however I read this:

Last year I bought an HP Z800 workstation s/h from Ebay. It weighs a ton and was designed as a high end cad/cam unit or a server. The reason was that I wanted to run a pair of GTX960 cards that are double width, without them touching each other for suitable airflow.

Sloppy research!

it will fit in that config in his current HP, if he's using the same board that i came up with in my search.

but it sounds like he wants another pre-built system, that has the same layout, but will take a standard PSU? I'm just unclear what he actually wants.

So in the meantime, you bought a "pig in a poke" or 'caveat emptor' as they say.
ROFLMAO.

Exactly what I was thinking of for later this year.

I just looked at Scan- custom pc and built a system there, no OS or GPU's, 850W PSU, i5 quad CPU, 8 GB RAM in a silent case at about £850, MoBo with 3 slots.

There are other places https://www.overclockers.co.uk/pc-systems/configurator, the place Richard uses https://www.cclonline.com/pc/custom-pcs/

Scan have Royal Warrant granted January 1st 2014

Or later this year (if the rumours are true) a Ryzen 3 system.

Ryzen 3 3300 (6 core 12 thread) for $99

Supposedly, the entry level Ryzen 3 3300 will pack six cores and 12 threads for only $99. If true, that's the same core and thread count as the 8700K for roughly a third of the price.

Just marketing all those cores. Unless as a home owner you are into processing video's where each core can process one frame, 6 cores is about the maximum required even for gamers. Games are not multithreaded.

https://www.tomshardware.com/news/intel-amd-threadripper-skylake-x-cores,37637.html has a good insight into multi-core usage, and how the AMD does not work well with Nvidia GPU's.

Well hosts 6,7,12,15 & 20 in the tops hosts don't seem to have a problem. :-)

Was looking around for latest thinking on app_config parameters for SETI WUs. This is the one I'm using now running E5-2699v4 with EVGA 1080 Ti's. Penny for your thoughts.

actually more and more games these days can and will utilized more cores. many old games will also support multi threading. the "you don't need more than 4 cores for gaming" mantra is quickly becoming outdated.

The latest info I could find.

thats DX11. and a very specific synthetic test.

what about DX12? what about Vulcan? what abut individual game performance? there's a lot of variables.

heres a 3 year old topic from reddit that is much more well rounded : https://www.reddit.com/r/gamedev/comments/44fux4/multi_threading_in_game_development/

tl;dr - game devs are all over multi threading, and in recent games it's becoming much more widely used.

I looked furthe and came up with this

The best CPU for gaming is the processor which offers the heady combination of powerful single-threaded performance, some tasty multi-threaded processing chops, and a price tag that doesn’t instantly nuke your bank balance.

Despite the dominance of multi-core CPUs in today’s gaming rigs, the difficulty in coding for chips with multiple processor cores has meant we’re still not seeing many modern game engines taking full advantage of the powerful CPUs many of us now have in our machines. In fact, since AMD has decided to take the fight to Intel in terms of core-count, even six cores is becoming more and more common.

But games are slow to catch up with our tech-harvesting ways. We had hoped with the rise in DirectX 12 games, and AMD’s promise of burgeoning Vulkan API support from developers, that the CPU would become more and more important for good gaming performance. That hasn’t come to pass, and the GPU is still the most important component of your gaming rig. But that doesn’t mean any old processor will do – you still need a quality chip to get the most out of your graphics card.

Moral of the tale - spend your money on a better GPU.

source?

I'm not saying the CPU is the most important, i'm really only contradicting your rather declaratory statement that "games are not multithreaded" which isn't true at all. games have been multithreaded for a long time now.

SOME games might not be
SOME games might not use more than 4 cores

but there are a lot of games that will and can use more than 4, and it's only getting more widely used as time goes on. that was my point.

your comment was a bit out of place anyway since no one was discussig games performance. this is the seti board, and seti will use every thread you allow it to. and the performance scales well with more threads.

are you running your hosts in VMs?

the 2699v4 is a 22c/44t chip, but none of your hosts seem to match those specs. and i'm scratching my head at your one host that reports 21 cores when it should be a 24 thread system.

as you don't seem to be opposed to Linux, you should look into running the Linux CUDA Special App which would increase your performance from the GPUs 2-3 fold

that's a good place to start. unfortunately due to the nature of these forums, since posts older than one hour cannot be edited, information tends to get scattered all over the place. so it's hard to keep a single post up to date with the correct info.

What's a VM??? If V is for virtual then the answer's no.

You can stop stop scratching Dick Tracy. Rig-01 has an E5-4668v3 with 12c/24t and I forget to update its cc_config that had an old <ncpus>21</ncpus> line. Thanks. You're right on the E5-2699v4's as they're on Rosetta now. SETI has E5-2698v4 20c/40t, an E5-2683 v3 14c/28t and a couple others. Not sure why this matters to you.

Sounds too good to be true, reading it now.

Thanks but what about my app_config???[/quote]

Does SETI have badges???

It’s not too good to be true. look at my hosts... or any of the other 35 or so top hosts. just don’t trust the GPU count in a lot of cases.

A 1080ti under SoG will do about 50k RAC. a 1080ti on the special app will do over 100k. To put that into perspective, a 1060 on the special app is about the same performance as your 1080ti right now.

Your app_config settings largely become null and void if you switch to the special app as the only option that matters is a single app specific cmdline variable in the app_info file.

If you stick with SoG, I would run 3 WUs per GPU (gpu_useage flag set to 0.33) and use an aggressive cmdline file.

-sbs 1024 -period_iterations_num 1 -tt 1500 -high_perf -high_prec_timer -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_lr 16 -oclfft_tune_wg 256 -oclfft_tune_ls 512 -oclfft_tune_bn 64 -oclfft_tune_cw 64

That’s what I ran under SoG.

If you decide to use the special app you’ll want to change the app config back to only running 1 task per GPU since it uses all available resources by itself.

Greetings,

Maybe for the time being, try EBAY for a HP PSU converter which allows you use a normal PSU.

This could be what your are after

Does SETI have badges???

Yes, Seti has badges for top 25%, 5% and 1%. Or bronze, silver and gold. It also awards special donor badges.
