Did you confirm that is ExpressCard slot? Look bigger though. Can you check mPCIe port? They usually located at the bottom, near RAM/HDD.

How about acer ferrari one?

Nah confirmed bottom has no ports at all, and yeah its an expresscard 54 thts why its big... So i guess i wont be able to do it eh

eGPU will work on x1 link only using mPCIe port that currently occupied by Wifi card.
Did you open the RAM/HDD compartment? Now we need to find out whether your notebook can do x2 link or not.

Oh I didn't, so I have to unscrew the little screw and open up the compartment into the HDD eh, alright will do it right now.

EDIT: Oh well no luck, after unscrewing I don't see any ports




So, I have a expresscard slot, HDMI, eSATA, 2 usb, earphone/mic jack... Would any of these be useful though I doubt they are.

First picture show Wifi card connected to mPCIe port. Please check in AIDA64 what is the PCIe port number for Wifi card.

BTW, check out post #15 in this thread:-
http://forum.lowyat.net/index.php?showtopi...post&p=45078530

This is what I got from AIDA64, I suppose that the "empty" port is the one ExpressCard one. Does this mean I have to remove my wifi card in order to perform a x2 link? Sorry for being such a newbie keep asking questions, I'm really new to all these computer stuff... Really appreciate your help.

Please see "PCIe x2 link" requirement at post #15: http://forum.lowyat.net/index.php?showtopi...post&p=45078530

Your Wireless card is at PCIe port#2. This show, x2 link setup is not possible on your notebook because card reader is at PCIe port#1 & it's integrated (not removable). Even if ExpressCard is at PCIe port #3 or port#4, x2 link is not applicable on your notebook.

This confirm you can only do x1 link setup. eGPU will not be able to perform best on your notebook.

Ahh, thr goes all my hope in an eGPU...

EDIT: Why does it have to be in proper numbers tho, eh 1,2 3,4 5,6

Because that is how Intel design the chipset. It's explained in chipset datasheets.

kizwan, can my laptop handle egpu?

this is my spec
Compaq CQ36-110tx
-2.26 GHz Intel Core i5-430M
-ATI Mobility Radeon HD 4550 switchable
-1 ExpressCard/34 slot

and how many TOLUD do i have?

anybody here with this laptop had done this? thank you.

Have u actually read the previous posts? It has specified how to identify the mPCI-E Port on ur laptop and whether will it support or not.

Your notebook have switchable graphics (Intel HD Graphics + ATI Mobility Radeon HD 4550)? If your notebook have active Intel HD Graphics, then you can do x1.Opt setup using Nvidia Fermi desktop graphic card. Since your notebook have ExpressCard slot, you can use PE4L-EC2C (or here). If you buy from Harmonic Inversion (HIT), you'll get free copy of eGPU Setup 1.x software.

x1.Opt is referring to Optimus setup. This setup required active Intel HD Graphics & Nvidia Fermi desktop graphic card. Optimus provide PCIe data compression which boost performance via PCIe x1 link. In addition to acceleration support on internal LCD, you will get better performance when using external monitor.

According to your screenshot, first PCI bus with 8 digits memory address is 0xC0000000. This means TOLUD is 3GB. So, you can use eGPU with 4GB or more RAM.

laptop had become desktop!! but good effort anyway

oMG!! can't wait to try this..but first i need to collect some money first...thank you Kizwan!

any where to get this locally? shop? thanks

hi kizwan, can my laptop handle egpu?
Model = Dell Studio 1555
CPU = Intel Core 2 Duo processor P8600 2.4GHz
GPU = 512MB Ati Radeon 4570 (discreet with the Mobo)
RAM = 3gb
I have ExpressCard Slot 34mm

Yes. In fact, your notebook support x2 link setup.

This is screenshot of PCIe ports when eGPU is connected to ExpressCard slot (PCIe port 4):-

This is screenshot of PCIe ports after moving wireless card to another empty mPCIe port (PCIe port 3):-
http://forum.notebookreview.com/attachment...s-port3open.png

So, you can do x2 link setup using PCIe port 3 (mPCIe port) + PCIe port 4 (ExpressCard). You also can do x2 link setup using WWAN port (PCIe port 1) + WLAN port (PCIe port 2).

I believe Dell Studio 1555 PCIe ports arrangement is similar to Dell Studio 1557/1558. See my eGPU setup.

Hi Kizwan,
thanks for the advice

which u recommend to connect with is more easier and faster?
i scare it will lag and alot other complication as studio 1555 spec is lower than 1557/1558

i would like to connect with ati 6850 graphic card- what is the watt power supply require? izzit 500w

i need your help to provide me the link or prescription onto which to buy
don't wana spend money onto part that not necessary

is the setup and installation difficult?
i can't find any ppl post on youtube EGPU how to setup step by step

what i understand is from PCIE 16x adaptor connect to graphic card ->Connect the GPU to the ExpressCard ->Get a PSU powering your graphics card
is this step correct? will it auto configure to port 3?

i don't know how to configure it to
port 3 (mPCIe port) +

what is the next step after plugin from express slot to notebook,
do i need to install any driver?
hmph alot to learn

Depend on the games. Some games required a lot of bandwidth while some are not. Considering your notebook specification, with x2 link setup, eGPU will perform roughly 80% from their actual performance.

HD 6850 TDP is 127W. TDP is not the actual graphic processor power consumption. Usually the actual power consumption is lower than TDP. However, power consumption can easily exceed TDP when you overclock & running power virus; Furmark is one of the example of power virus. It is not actually a virus but they're called by that name because of they can make GPU to consumed a lot of power than regular use. So, we can use TDP as our guideline when choosing power supply. For TDP 127W, you can use 130W - 140W AC adapter but you'll need to modified the connector because GPU use 6-pin/8-pin PCIe power connector(s). ATX PSU is recommended for eGPU.

For TDP 127W: (127W * 10%) + 127W = 139.7W
Calculated with 10% margin, the power supply you looking for can supply at least ~140W on the +12V lane. On the PSU, there is a sticker with writing on it where you should see +12V, +5V, etc. Look for the amperage (current) value for +12V.
140W / 12V = ~12A
So, the PSU should have at least 12A on +12V lane.

Look like you need PE4H + two PM3N or PE4H + EC2C (ExpressCard) + PM3N. You also need to buy two cables (default package only come with one cable).

I like to think eGPU is for enthusiast; who like to see what their notebook can do.

Your notebook should be able to boot with eGPU connected. I mean, connect everything, power ON eGPU & power ON notebook. Then you just need to install the graphic card driver. For x2 link setup, you will need to buy DIY eGPU Setup 1.x software ( http://forum.notebookreview.com/6295529-post641.html ).

Before you proceed, you will need to identify the PCIe ports. Install AIDA64. Go to Motherboard >> Chipset >> "South Bridge". Look where your WLAN device (broadcom) is connected to. Write down the PCIe port number. Then shutdown your notebook & open the HDD/memory compartment. Look for empty mPCIe port(s). Moved the WLAN card to another mPCIe port(s), boot your notebook & check in AIDA64 the PCIe port number for the WLAN card now. This process is important because you will know the PCIe port numbers for all of the mPCIe port(s). Remember for x2 link, you will need either PCIe port 1 + port 2 OR PCIe port 3 + port 4.

Again, this is for enthusiast. It can be difficult & overwhelming for some people.
