Dell T7600 works fine with RTX3080

Nice! I read somewhere that these Ampere RTX cards use new types of power connectors. Is it true that the 8 pin sockets are non-standard? Do you need to use an adapter of some kind?

Hi @me.myself.i ,

It got 2 GPU power port and both in standard 8pin. While T7600 already got 2 8pin female port on the power distribution board, I can connect them with standard 8p-male-to-8p-male cable. I'm using 2 G3W07 cable as picture below.

That's good to know! I read that Nvidia is planning on introducing 12-pin sockets. Maybe that's for the Ampere based Quadros?

Simply search "MSI RTX3080 power socket" and it returns "2x 8pin". Together with the GALAX on my hand, I believe that new 12-pin socket only exist on Founder Edition cards. But don't worry! Check out this article from TweakTown and it shows that both 3080 & 3090 FE cards comes with a 12pin-to-dual-8pin converter already.

Thank God I found this post, I've been wondering about this for a while. So great, 113mm will fit and you've identified a model which is a huge help! However, do you know what the absolute max height that will fit? We're there any others you looked at that are on the smaller side?

I bought a used Asus Rog Strix 1080ti over a year ago, but can't get the side panel closed on it because it's just a little too high at 134.2 mm (5.28 inches).

It works just fine but if I do another upgrade I'd really like to be able to close the case and know what buying options are available to me.

Hi @ericlampi ,

Related document you can find officially from Dell web site nowadays is the Owner’s Manual, which descript

it as “full-height” only:

However, there once exist another document named as Technical Guidebook that can still be located elsewhere, with detailed height value: 11.13cm

Practically my RTX3080 at 113mm slightly over the 111.3mm limitation but still marginally fit. I’m afraid any number over this value may not work on T7600.

Apart from card height, you may attention to power socket as well. In order not to let those PCIe power cables in heavy contortion, I added these kind of 180 degree converter:

Thanks! I'm interested in your cpu cooler mod. What are you using? How's the temp comparted to the original heatsinks?

Hi @rollan13 ,

It's TMJK2 which originally designed for T7910 CPU water-cooling but also works on T7600. Maximum CPU temperature under stress test drops significantly from 89°C to 73°C, and keep at 4X°C on generally usage. Check out this thread and I left a reply there with more details.

I noticed on your 7600 that you have the 7910 liquid coolers installed. Did they fit OK or did you have to cut off part of your DVD player bracket to make it work? 

Hi @mw7301 ,

They just fit in without any modification as what you can see in the 1st picture..

For the liquid coolers did you keep keep the fan BIOS settings at "Auto"? Also did you install the T7910 vented panel?

T7910 Vented Panel

Hi again @mw7301 ,

Yup, system fan settings as Auto perfectly works.

It's hard to locate the vented side panel even on the refurnish market, and not at a reasonable price level (over US$200 with shipping cost). Instead, I added a 8cm fan at the back of the chassis. Spent just a few bucks but helps a lot.

Hi!

That side panel was extremely hard to find and they want a lot for it considering what it is. I guess the resellers know that everybody wants one. After searching for a long time one actually just popped up on EBay and its $159.99; https://www.ebay.com/itm/NVY9X-Genuine-OEM-Dell-Precision-T7910-Tower-Vented-Black-Side-Panel/143916528987. Considering that the regular side panel is $15-$20 its a total ripoff but they are popular.

I promise this is the last question! you have the RTX3080 installed and I was wondering if you have to change that BIOS setting for PCI video memory. I can't remember what its called but I think it only has two setting; small and large. If you did have to change it did you notice in performance? 

Thanks a lot for all the information!

Actually I doubt if a maze panel like that without additional fan make any significant difference. Practically my setup with an fan adding at the back do increase air flow within the chassis and keep it cool.

You mean the PCI Bus Configuration and PCI MMIO Space Size I believe. I set them to 256 PCI Buses and Large respectively., and they have nothing to do with GPU performance. You may check out PCI configuration space on wiki to learn more about it.

hello friend what processors accompany your graphics card?
