External GPU for W500 with Advanced Dock [ Edited ]

[Chamelleon]

Hi,

Few weaks ago I bought  Lenovo Advanced Dock and Sapphire Ati Radeon HD 6570 with 2GB memory but it's not working and laptop still rebooting on startup. I set up all things in bios, disabled build in Ati FireGL5700 and set PCI as primary booting device. So it must be problem with power on PCI-E slot. I know that I can make it on eGPU by ExpressCard but I don't need much powerfull card, I just need to play World of Warcraft and Diablo 3 on middle detaild and min 30fps.

So I need best card I can use with this Dock. Should I test Sapphire Ati Radeon HD 6570 with 1GB memory or maybe I could try something better or just leave it cause I wont find any descent GPU to play this 2 games??

Sorry for my bad english.

Hi. You need to provide some more information. What OS? At what point is the reboot? Is the OS restarting and is there a BSOD associated with the reboot? What model dock are you using? It could be your card is not supported.

Oh and you could still do an eGpu solution using the current card (and additional parts) but if you bought the dock for this, you may need a compatible card.

Lenovo Advanced Dock, Model 2503, Windows 7 Ultimate x64. I set up in BIOS to boot on PCI Express and default GPU is internal Intel card, not ATI FireGL V5700. After turning on laptop there is no sound and only black screen, I can hear cooler on PCI card starting and after 3-5 sec laptop is rebooting. I think there is too low power on PCI card and thats why it going to reboot and thats why I'm asking for any clue to choose some graphic card to this dock.
My Lenovo config is:
CPU - Intel T9800
8GB Ram 1333MHz
Newest drivers and BIOS
Windows 7 Ultimate x64.
Someone on this forum said that it can be fault that CPU need more power and thats why PCI slot in Dock can't working with this GPU but there is few people who are using this GPU in this dock and it's working fine. So maybe they're right and it means that my CPU needs more power and I need to buy different GPU and thats why I'm asking which should I buy.
Thanks for reply.

Yes. Could be power or some other PCI incompatibility. No suggestions on an alternative card, sorry.

Have you gone here: http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-61232

It shouldn't be PCI incompatibility cause like I said few people are using this card with this model of Dock and they don't have any problems with it. Maybe I'm gonna try with the same card but 1GB version, it should needs less power than 2GB, but maybe someone have some idea about better card before I buy this 1GB version.

Then what makes you think it is a interface power issue and not your dock that is the problem? Do you have a PC you can try the card in?

[Chamelleon]

Yup, card working in PC without any problem and I'm using Creative X-Fi titanium PCI-E without any problems so there is no chance for faulty card or PCI slot.

Not to HJ your thread but as I've never used an external graphics card before I have a quick question.
Is it exclusively only available via an external monitor or can it be utilised with the laptop screen itself?

Hi. External display.

Hi. No chance of a faulty PCI slot you think? Looks like the issue could be your dock if you say the card works fine in a PC. If you still cannot get it all working together, the dock you have with the card you have are probably not compatible together. Sometimes that's the way it works with unsupported stuff. It may or may not work in general and you could still have other issues when it does work. Looking back on what you mention about enough power to drive the card, I really am not sure if this is part of your issue or not, but I would think if this card is working with these docks as you say others are doing, I would check my dock. I highly doubt there is any issue where one dock can drive the card with more power than another dock, e.g. like yours and what you mentioned about power. If you think that is the case, and have some doc/maybe testing to back that up, then by all means try the model card with lesser power requirements but I don't think this is your issue and I would not spend my money on another card yet, I would be focusing on docks right now then perhaps another video card. You mention a Creative X-Fi titanium PCI-E, that works in the dock? I don't have any of this specific hardware so this is about all I can add to your issue.
