Z620 GPU Upgrade: Power connections K4200 for video installed with Tesla K40

[srgmntl]

Hey everyone,

Long time lurker since I jumped on one of these z620 puppies on Amazon last summer. Excited for my first post!

As the title suggests, I've a K4200 on the way and am looking to compliment it with a Tesla K40.

Mostly working on Davinci Resolve, Premiere/After Effects, and trading platforms.

My Station:

Z620_v2: Dual e5-2670 v1 - 96gb 1333Mhz Ram - 960 Gb SSD - 1TB NVME M2 - 4TB HDD

I already bought the K4200 but haven't received it yet, does this card take up my power connection that I'd need for the K40 or how have you guys actually plugged that card in along with your primary video card??

There are threads on here of people using the Tesla K40 but can't find specifics about power solutions.

Should I have gotten a K2200 instead?? Ugh

This silly market really doesn't give us much choice in terms of availability so it's very difficult to know how to get a good deal and compatibility. 

I actually am having to flip a 3070 that I would've loved to make work here.

Thanks for reading and any help! Have a great weekend!!

the main difference between the k2200/k4200 is the onboard memory with the k4200 having twice (4GB) ram

the second difference is that the k4200 is about 50% faster overall

you may also need a QUALITY 8 pin to 8+6 pin GPU pwr adapter

Thanks for your reply!

Figured I kinda backed myself into a corner going for the K4200 if I was considering a dual GPU system. If prices for newer second hand cards stays so high, I may just grab another and make the best of it for now.

The more I looked into the K40, it just seems like way too much hassle for not enough in return probably. With the dual CPU, it'd be a nightmare keeping it cool and usable.

Srgmntl,

A couple of corrections and comments concerning the Quadro K2200, K4200, and Tesla K40;

Both cards are 4GB and PCIe 2.0, with the K2200 at 128-bit,  rated at 68W -which mean no added power connection is required, and with 640 cores while the K4200 is 256-bit with 1344 cores at 108W so  a power connection is required; it only needs 1X 6-pin for the +33W the PCIe slot does not supply.

The K2200, K4200, and Tesla K40 are all Kepler series and my understanding is that the primary GPU and the compute GPU have to be of the same series.

The Telsa K40 does need the good quality 8+6-pin; it can draw up to 245W.  The Tesla K40 will not be easy to cool under long, heavy loads such as video rendering. In a z620 if the K40 is placed in the second CPU slot it may be too close to the bottom of the case and the fan will have an absolutely minimum clearance for air circulation.  Try it, but consider placing the dual slot K40 in the upper GPU slot and the single slot K4200 in the lower GPU slot and changing that slot (Slot 5 I think) in BIOS so the K4200 on the bottom is the primary GPU. Make sure that the lower front case fan and front panel are clean as can be of dust. Consider having a temperature report window on top for a good while and if the temperature creeps up too high on the K40, consider moving the fan profile up one asterisk. Those Tesla computer units are more comfortable in the very-high CFM environments of servers.

The office systems have used both of these and both are still quite useful cards today.  The vintage system here, a 2007 Dell Precision 390 currently has a K2200 (Passmark 3D = 3300) and a K4200 was tried in it (Passmark 3D = 3467 (2016) before that was used in z420_2 (Xeon E5-1660 v2, 6C@ 4.2GHz) where the 3D of the same card = 5077.  That's the difference with higher clock speed and IPC architectural advancement. The Precision 390 can not make full use of a K4200 but a more modern system can as in the example of z420_2, Probably, z420_3 at 4.3GHz would be even better, although as both cards are PCIe2.0 there's a limit.  The current Passmark average for the K4200 = 4298. By the way, the K4200 was replaced in z420_2 with a Quadro P2000 5GB (PCIe 3.0) and 3D = 8945.

They're both quiet, single slot, relatively cool running (well, for the time), lower power, blower-fan cards, and not outrageously priced these days as well. 

Personally, for such heavy workstation use, there would be a far greater benefit from running a single GTX 1080 TI 11GB, with 3584 CUDA cores, it's PCIe 3.0 and was made in a couple of blower-fan models. The prices are beginning to be only semi-stratospheric.

Hi Bambi, 

Thanks for replying! Yeah it seems like I should've gone for the K2200 if I was going the double GPU route but at this point, looks like the best bang for my buck is the 4200, and possibly doubling that if it comes down to it. 

Since more powerful older cards have doubled or more in the used market since I bought the system, I don't mind paying for a third of performance if it's at a 6th of the price (K4200 or two vs. 1080ti).

I'm also saving up for a Ryzen/Ampere build, so I don't see the value in paying for a used card what a new Ampere would cost, knowing THAT system has a lot more runway. Already bought the 3070 and 3900x but I'm buying components as I save up making time for the hard to find to become available (looking for a 5900x/3080 or even 3090 if bitcoin continues to rise hahaha 😉).

So this Z620 is my bridge system while building that one and I wanna make it as useful as possible. I've also been Mac-based for almost 16 years so getting the lay of the land in terms of hardware and upgrades is kinda new for me haha.

Cheers and thanks for your help!
