Hi all, does anyone know where i could sell my PE4H to Expresscard kit, its about 3 months old and in perfect condish and I m in the UK.

Regrettably, although i got my eGPU up and running no problem, it wasn't performing very well in games so i ended up buying a desktop and putting my graphics card in that. My laptop was just not suited well (2009 MBP) as it was restricted by the X1 link.

To get the eGPU to work well, i would have had to buy a Lenovo, or a thunderbolt Mac or something, so i just went for a cheap desktop instead because my Mac is fine for everything else i do.

I look forward to this developing in future, its already well on the way, due in no small part to Nando's efforts, thanks again for all your help, and sorry if this is not the right place to ask about where to sell components.

PS I signed your email petition for NBR Nando, i hope it got sorted out in the end!

You are running a HD7750 @ x1 1.0. There is no Optimus pci-e compression running there. Please read the CYAN x1 section here to understand why your performance is poor in some titles. If the MBP has a NVidia chipset then it's running at best performance. If it's got a Intel chipset then depending on what port the expresscard slot is on you may be able to apply the X1E tweak to get better performance.

If your 2009 MBP happens to have a Intel iGPU (4500MHD or Intel HD), then consider swapping the HD7750 for a GTX460/GTX560. Then you'll get significantly better x1.Opt performance. If not, then you may want to upgrade to a Sandy/Ivy Bridge iGPU-equipped system so could run x1.2Opt, faster again or even a Thunderbolt-equipped notebook and watch this space for implementations trickling in. They have the most bandwidth x2 2.0 (BPlus TH05) or x4 2.0 (Sonnet Express Box)

Thanks very much for this Nando! I can confirm it is an Nvidia chipset according to CPU-Z and AIDA 64, i assume they are pretty releiable, so no X1E. The iGPU is an Nvidia 9600M GT, so i think optimus is not possible? However, I noticed in the post above you say if the OP can disable the NVS 4200M then 1.2Opt would be possible, i thought you could only do it on intel iGPU's? If the OP in the above post can do it, would i be able to disable my 9600M GT to use Optimus with an nvidia card?

I guess im just confused why my current set up can run more modern titles and not older ones, one might assume it would be the other way around? and i thought an ATI set up at X1 woudl be better for DX9 games whihc the Cand C titles are i think

Thanks again for your help

Hi all, really glad to see you here! I feared the worst when i saw the NBR debacle, thanks to Nando for keeping it going

I m hoping for some kind advice from you guys.

I have an egpu set up and working:

System

Macbook pro 2009

Win 7/64 with bootcamp

2.66 core2duo

4GB ram

egpu

550 ocz modular PSU

sapphire HD 7750 via expresscard @X1

My benchmarks are ok, not as good as some but ok:

3dmark 06 ~12000

3dmark vantage ~9000 with GPU score ~14000

RE5 variable with DX9 and DX 10 around 80 FPS

Heres the thing, i like RTS games and i set this up to run old C and C titles, eg. tiberium wars, red alert 3 etc. but the set up struggles with these games even thought they are from 2007/2008. I get rubbish FPS and it crashes periodically

At the same time i can run Starcarft 2/diablo 3 on ultra setting with no issue at all, i dont understant it. Surely if it can run these games OK and RE5 at 80 FPS it should run 4 year old games??

could anyone suggest why this might be?

Thanks for any advice

PS. I ve tested the PSU with multimeter and it is fine
