DIY eGPU experiences

[Khenglish]

Hello,

When I look at Device Manager with Resources By Connection, there are two PCI Bus entries.

[00000000000A0000-00000000000BFFFF] PCI Bus
[000000009FA00000-00000000FEAFFFFF] PCI Bus

This means I can't use an eGPU, right?

Thanks for explaining this to me!

No, you can use an eGPU. Your TOLUD is very low at 2.5GB. You won't have to run compaction for sure.

Masaharu at BPlus wants to know the ideal cable length

What would be the ideal cable length for you on the new PE4L/PE4H with soldered cable ends? Eg:

1. 45cm/1.5ft cable (this is what suits me)

2. 60cm/2ft like the cables that were supplied with the previous PE4L/PE4H

3. 100cm/3.3ft like Villagetronic's ViDock

4. longest possible that passes pci-e 2.0 testing where the user could fold a 200cm/6.5ft cable to to become 60cm/2ft or extend it out to be 100cm/3ft (if BPlus approve of such folding without damaging the internals of the cable).

I'm thinking maybe they should create either a (1) or (2) for most users and a (4) to satisfy users requiring additional length.

Please advise what is your preferred cable length. His latest message is below:

Now, I need a help. Regarding cable length, we would like to know the optimized length, because the cable cannot be changed. The length of PE4L v2.1 sample we sent you is 25cm.

We suppose it might not be long enough, but should not be too long for handling. So, we would like to know how you feel the length and the optimized length.

I've been using a 45cm cable. More length would be nice in certain situations, but 45cm gets me by.

I see max cable length varying from system to system and PE4L to PE4L, so I'm thinking they shouldn't go for max length because then some PE4Ls and laptops of slightly lower quality won't make the cut.

If I were bplus I'd find the average max cable length, then shorten it by around 30% to add in some margin for error.

I'd say 60cm sounds about right.

Anyways, I have a quick question. Can I use the E2C2 in an ExpressCard/54 slot without an adapter, or will I need one? I know its only like $2 for an adapter, but I'm wondering.

“In medio stat virtus”

To me 60cm is good enough. Consider that:

PE4L has the plug ahead of the long side of the GPU, so if you want to keep all your cables coming from the same direction, you have to consider the dimension of the GPU and "remove" it from the global length. Considering the average GPU length of 21cm, you can expect at least 15-16cm of "shadowed" length below the GPU, leaving 45cm (plus the EC2C i hope) of spare cable available to make curves and even "mirroring" to the backplate of the GPU if you want to bring the cable out from the video out connectors side.

The draw should explain better what i mean.

100 cm/3.3 ft sounds right...
The longer the better though...

Would I be able to make use of an eGPU setup and see substantial gains with my Gateway laptop in the sig?

A Gateway P7805-u is not x2 capable nor can do x1.Opt. The onboard dGPU will be faster than anything a DIY eGPU can offer.

Consider then the changeover costs to go to a better DIY eGPU candidate notebook. Eg: a i5-2410M 14" Lenovo E420 can be had for $500, a GTX460-768MB DIY eGPU for ~$200 and a 17+" LCD available for low s/h cost. Such a system will not only give faster CPU and GPU performance than your P7805u but will be more portable and give better battery life. A Dell Vostro 3750 is a budget 17" notebook if you have a liking for 17" systems.

If you refer to the thin-and-light link in my sig and scour the Dell/Lenovo/HP outlets then you may find an even better specced candidate notebook for lower cost. Dell Outlet being particularly sharp on pricing during their sales.

Disregard.

selling my PE4H,

Ended up building another desktop so didn't really use it.

Thats the FS thread if anyone is interested^

Thanks
