bump...
is this topic being discussed further somewhere else?
I just started looking into this mod again and I could use a few tips concerning a solution for my T61 + adcanced dock + radeon HD gfx
From this and other threads, it would seem that it is possible to use:
(i) Certain Radeon Cards (like 4350 & 4550) that have a low enough Power consumption (<50W?) to be used "natively" in the dock, or with a Pci riser card in case the card physically to to big for the dock.
(ii) Certain Radeons cards (like 5770) with a bigger power consumption, using an external PSU (and the riser card solution)
It seems then, that the cards that will NOT work, includes:
(a) Most or all Nvdia Cards (like 7800GT) due to a Pci x16-> x1 scaling issue?.
(b) Any card using more power than the dock can supply while lacking the option to connect an external PSU
I need help devicing a theoretical list based on the assumptions above.
At the moment, I am looking at a few cards that sell for next to nothing, in order to try the mod and get a bit more performance than offered by the intel Gfx in my T61
I am looking at HD4550, HD5450, HD5550, HD4650, HD4670 and HD5670
as they all sell for less than 100$ in DK
I am looking at Sapphire, XFX and Asus, and most of these cards (exept 5670) are passively cooled.
Obviously (I think), the HD5670 or the passively cooled HD4670 provide most value, but the question now, is to figure out which cards will work natively as (i), which ones will work with a PSU (ii), and finally, which ones that will not work at all (b). I think that 5670 and 4670 lack the external PSU option and I am afraid that they will draw too much power for the dock to sustain them?
Any help is greatly appreciated.
Note: the primary purpose is not gaming but rather Photoshop, Premiere, Blue-ray and such, whereas I do a bit of occasional EvEonline/wow gaming (and yes, these games DO require much more than an onboard gpu
