DIY eGPU experiences

Could you provide some info about performance increase in Premiere with GTX460?

Are you able to play HD1080p videos without any lags and did you get advantages of encoding speed with it?

I have Lenovo T510 with Quadro NVS 3100 now and I can't even play 1080p video preview in Premiere and want to use older GTX260 or 280 as accelerator for Premiere.

Previously on my desktop computer I'v got GTS 450 and with HW acceleration I was able to play any HD content in Premiere smooth and get some advantage of acceleration during encoding final files.

BTW GTS 450 is not so good card for Premiere, only 10-15% speed increase above 8800-9800GTX

Nando4, you are a demi-god! Thanks so much for your help, my system is up and running with mercury playback engine in premiere.

That being said, for those applying the hack to adobe premiere cs5 and 5.5 to get the mercury playback engine working, as Nando4 said, you can go here for instructions: Hacking Adobe Premiere CS5 to enable more nVidia CUDA cards | KRAMA i.news - blog.krama.tv
HOWEVER, after I followed all of the instructions, premiere would give an error when opening saying that it couldn't find the video player drivers (something weird that wasn't as obvious as unable to find graphics card or graphics card drivers, plus all my drivers were up to date) and it would shut down. The only solution I could find was uninstalling then reinstalling Adobe Production Premium. After that I simply followed the first step of the hack; adding the GTX 460 to the list of supported video cards in the file "cuda_supported_cards.exe". When I opened premiere after this I was able to select mercury playback engine for hardware. My recommendation then when doing the hack would be to check premiere after each stage of the hack to see if MPE for hardware is enabled, because you might not have to do everything in the instructions.

Now my specs:
MSI A6200-021us
i5-430M
8GB ram (MSI claims that the bios only supports 4GB, but I heard that wasn't true and in my case it was not true)
64-bit windows
GTX 460 (not OC'ed, might do that, will get back)

3Dmark06 results:
12539 3DMarks
SM2.0 Score: 5464
HDR/SM3.0 Score: 6526
CPU Score: 2604
GT1 - Return To Proxycon: 44 FPS
GT2 - Firefly Forest: 46 FPS
CPU2 - Red Valley: 1 FPS
HDR1 - Canyon Flight: 78 FPS
HDR2 - Deep Freeze: 52 FPS

The website says that my score is low for similar systems, but my scores were an average of 86% of comparable systems which seems pretty damn good to me through an X1 connection!

I paid $550 for this comp, adding the 4gb of Ram and now this video card is really giving me amazing value and doing as much as can be hoped for as far as future proofing (for at least another year right )

Thanks so much again Nando4 and everyone else who participates in this forum, you guys rock!

Move to a dedicated DIY eGPU host?

A user (who wishes not to be named) has volunteered a vbulletin/phpbb equipped system to host a dedicated DIY eGPU forum.

I will be going for vbulletin, if its necessary. Technically vbulletin is cut out for addons but phpbb does exactly same job, in terms of posts and bb codes. Though $200 for a license, holy . I don't mind spending it because its one time payment but I need to know if it will be any use. Host that I have used before basically doesn't restrict any CMSs (Content Management Systems) to use so I will be able to put a wiki there too.

I wanted to see how users feel if we made such a move? Some brief pros/cons:

Pros:
+ subforums so info could be partitioned better
+ wiki would allow user-wide editting of the current quicklinked info

Cons:
- new website, new user registration, no guarantee on uptime, split off from other NBR discussion.

I'm also watching if NBR can implement an all-edittable first post summary as requested in NBR Forums Suggestion Box . NBR could help us also to just make a dedicated eGPU or external graphics areas that has been denied on two previous attempts to get going.

I personally think it should stay here, but get its own subforum in the Gaming section. Seeing as is is a big part of the NBR community, I think it would be a bad idea to make a whole new site.

I agree but my two previous attempts during PMed discussion with the head moderator, Charles P Jefferies, failed to get us a dedicated area. I recall it was passed for discussion with the moderators who didn't allow it to proceed. I initiated the first discussion and the second one upon SimoxTav's initiative.

It was also not clear why the moderators resisted allowing such a subforum. I would have assumed there is not really that much to moderate in our discussion area. Only really responding to flagged posts, which are also a rarity here.

Can anybody propose a different approach a third time round such that we may get a subforum? We do now have the option to go elsewhere if there is resistence on NBR to provide the tools deemed as necessary. I was thinking a polled question along the lines of Does NBR require a dedicated external graphics subforum? YES/NO/candy with as many YES votes as possible would be the most likely way for us to get such a subforum.

I created a poll that can be found here:


Dedicated External GPU (eGPU) subforum POLL.

[kevmanw4301]

Nando, that seems like a great idea. I'll be voting in the poll ASAP. Someone can get the ball rolling with the mods, but we should wait until after the poll has gathered sufficient votes.

I ordered everything today... hopefully shipping won't take too long. I'll update with results when it all gets here:

Latitude E6420

eGPU:
PE4L from BPlus
COOLMAX ZX Power Supply
GeForce GTX 570 HD 2560MB

[TPU] Ivy Bridge PCI-Express Scaling with HD 7970 and GTX 680

Btw is there still no one that have tried AMD cards with pcie2.0 ?

This is an AWESOME news. This means GTX670 is my next purchase

an 1.2opt is equal with what ? x4 1.1 ?
it could be good perf with a gtx680
