Supermicro X10SRH-CF

Yeah, considering slot 4/7 only has 12 lanes total between them supposedly definitely seems off.
Thanks for the info, with that in mind this should work then:
Slot 7 (x4/x4?) - SAS controller (x4 limited~but only needed for 2 hdd, may downgrade to a x4 sata card)
Slot 6 (x8/16xslot) - GPU for transcode
Slot 5 (x8) - 10Gb Networking
Slot 4 (x4/x4) - 2x NVME Adapter

I'm going to just cut the back off one of the x8 slots and put my transcode GPU there
That way the x16 is free for an Oculink card at x4/x4/x4/x4

Something like this...
Slot 7 (x8) - Nvidia P400
Slot 6 (x4/x4/x4/x4) - AOC-SLG3-4E4T
Slot 5 (x8) - Spare
Slot 4 (x8) - Mellanox CX3 NIC

If I have Slot 6 bifurcated to x4/x4/x4/x4 is slot 5 still usable at all?

The slot 6 is supposed to be x8 electrically.

Ok, so I'd have to something more like this then?

Slot 7 (x4) - Nvidia P400
Slot 6 (x4/x4) - AOC-SLG3-2E4T - dual port
Slot 5 (x4/x4) - AOC-SLG3-2E4T - dual port
Slot 4 (x8) - Mellanox CX3 NIC

 

[Spartacus]

why x4/x4 for the slot 4 mellanox?
Thats a x8 card and slot, 4/7 are linked together bifurcation wise so it could easily be x4/x8 in auto settings.

that does bring up a good question how much throughput does a transcode GPU actually need? given a low end solution like the p400, what about higher end like a 1660?

oops. Guess that port doesn’t need it

You’d be surprised how little performance you lose between x16 and x4 for a GPU.

It might be 3% or something, and it’s been shown that you need 2 x titans to push the limits.

Good to know i had outlined mine so they get mostly full bandwidth execept the gpu which will run x8 in the x16 slot.
But I may get a x16 to x4 riser cable instead then and shove it in slot 7 too, just so I dont have to cut the slot. The dual slot card wouldn't fit there anyway without blocking another port.

hmm, how would it affect it bumped down to a 2.0 x4 slot? Or a 2.0 x2 slot? (Slots 3/2 at the bottom)

edit: just to reiterate this is solely for transcoding purposes notation, Likely aiming for a 1660

 

[wallysimmonds]

Picked one of these up. Now need to get a relatively inexpensive V4 chip and some ram...

Just to note, if you get a board with a 1.1 bios, you will need to update bios on a v3 chip first.

Some people have been getting updated/old bios and IT/IR Sas.

 

[wallysimmonds]

Ahh. Not wedded to a V4 but the V3 pricing doesn't seem that much cheaper!

This unit will replace a SC2600CP system, with a couple of E5-2670 v1s

1650 Super also uses the newer Turing chip, if you wanted to possibly save a few $$.

That's why the single slot quadro cards are so good. You can get a P400 for ~$80, or a P2000 for ~$220
P400 and 1650S/1660 both have 1 NVENC chip, and can support 2 concurrent sessions, wheras the P2000 has unlimited sessions.
But, you can also patch them so they can do unlimited streams, and then you're just limited by the amount of ram on the card.

The 1660 will have slightly better quality transcodes as it's using the newer turing chipset
A company called Colorful makes a single slot 1660, but it's pretty much impossible to find in the Western world.
If you have the right contacts in Asia, it should be fairly easy to find though

What's your budget for the CPU?
I managed to score a 2680V4 for less than $300 a few days ago

I'm aware thats why I'm targeting the 1660 for the turing chip so it can do HEVC.
Who knows what'll happen with ampere at the low end around the start of next year though, I'm not in a huge rush I rarely do more than 2 transcodes simultaneously anyway and all my stuff is 264 format currenly.

For comparison that good priced 2680 v4 is under $100 for the V3, so not sure where you're getting your pricing at but the v3 are regularly 1/3 the price (or less of the V4).

 

[wallysimmonds]

I really just did a quick ebay search, and I guess my post was more to solicit 'what should I be paying'.

I'd like to be spend between 1-2 hundred US, less is better obviously.

 

[Spartacus]

You can pick up a 2690 v3 for under $200, gets you 12c/24t with about the highest core clocks available for that price range (2.6/3.5 turbo). ~ the v4 comparable is about $850. And as zerosum mentioned the 2680 v3 is $100.

IMO the best bang for buck is the 2660 v3, its 10c/20t, decent frequency (2.6/3.3 turbo) and is under $100 (usually about $80).

This one is $85, but I'd bet they would take a 75 or 80 best offer (maybe less): Intel E5-2660V3 SR1XR 2.60GHz 10 Core Processors | eBay

 

[wallysimmonds]

Thanks Spartacus, I agree - looks like the 2660 v3 is the one to go for. Are ES worth looking at or should I avoid?

 

[Spartacus]

For the already low price, I personally stick with the retail just to avoid headaches and/or having to revert to older bios versions.
It 'should' work but more worth the risk for the higher end ES/QS CPUs, not so much at the mid-low end IMO.

Basically the reason the V3 are so cheap is they're mostly cycled out of enterprise datacenters already, the V4 are still in use.
I would expect the V4 to plummet in price the next year (or sooner) as they are phased out of the datacenters for newer equipment.

 

[zer0sum]

ES will have lower frequencies and possibly other odd stuff like missing features.
I always try to avoid them unless it's basically a throw away $5-20 CPU for testing.

The 2678V3 is also worth a look at $99 as it's identical to a 2680v3 and is 12C / 24T and 2.5-3.3ghz

Good stuff here if you really want to dig into the frequencies each chip can run in different workloads.

Thanks for the replies guys. Worth noting I'm based in Australia so many sellers (unfortunately) won't ship to me.

 

[Spartacus]

Ouch that does put a dampener on many sellers, best of luck!
There are alot of options, maybe a few might be willing to chunk it over the fence to ya.
