I've been trying to get help but to no avail . I also have a modified bios which bypasses the whitelist problems on my other laptop . With that laptop egpu runs ok, but just as good as express card.

Just be patient and wait some time. He's probably busy, but in the end he always comes back to answer.

Yes, mPCIe and expresscard are the same, performance-wise. They both rely on the PCIe 1.0 bus (=2,5Gb/s).

I guess you'd need to search for a modded bios with whitelist removal. It should be easy to find it for your T510.

I seem to not have any problems with the connectors near the ram underneath the laptop but the laptop I'm tryna get working only has expresscard and mpcie underneath keyboard

And remember, if I'm not mistaken, that not every mPCIe port can be used for a x2 1.0 setup. It needs to be an odd numbered port and it must be contiguous to the expresscard port number: e.g. 1-3, 3-5, 5-7. Or something like that.

The same thing happens with just the mpcie connected.

Just wait for Nando4 to be sure (he's THE man ), but I'm quite sure you are facing the well-known whitelist problem of Lenovo bioses. If that's the case, I think there are two solutions: either hotplugging the mPCIe connector after the bios post (not advised really), or flashing a modded bios with no whitelist (advised).

But again, wait for Nando.

noric probably meant this thread: http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html

Yeah, sorry. I didn't remember that the implementation list was moved from the first post (where it was until some time ago).

T510. Thanks for your response

Yes, it's possible, but it's necessary that your two ports (expresscard and mPCIE) are odd numbered. Open up a software tool such as AIDA64 and look which port numbers those two have.Anyway, in the first page of this thread you may find more information. There's also a chart, in which you can search if there are other T510 implementations.

Hello. I'm using a Lenovo laptop. I've been successful in implementing my egpu setup using the express card and pe4c. Now my question is this : are there any optimizations and increasing the band with? Could I use the x2 port and route that to the mpcie for extra bandwidth?

Which Lenovo model do you have?

I have a GTX 750 Ti working with my Sandy Bridge ThinkPad (no internal dGPU)

Which ThinkPad model are you using? I have an E520 and I'd be interested in a similare setup as you have (750 Ti).

I also dual-boot Linux on my laptop

Did you manage to get it working in Linux?

Assuming the card doesn't require over 200W, is the XBOX360 PSU still a viable option for powering the PE4C? Or is that an old suggestion? Is the DA-2 preferred? I know some EXP GDC people are having some trouble with the DA-2 voltage fluctuations.

Best solution is still an ATX PSU?

I think it's still viable and I agree with you that the DA-2 troubles I read about make the Xbox360 PSU still very interesting.

Has anyone tested (other than brute performance) maxwell's behaviour in PCI-e intensive scenes, such as the well known grass scene in Crysis? How does Maxwell compare with Kepler in such circumstances?

Thanks.

One feature request to BPlus, if possible: please make the new 2.1 release turn on/off based on expresscard power (= laptop is on/off). In short, like Exp Gdc does.

this thread is great (it would be better if it were searchable haha, i had to write a script to download it and format all the pages into one so I could use Ctrl+F).

I often have the same problem here. I can't believe there's no autopager (Firefox add-on) rule for a site like techinferno. Any reason why nobody has ever created one?

Sorry for the OT.

Folks, requested BPlus give a cheaper PE4C 2.x option inc 220W AC adapter than the US$113-shipped they have now to compete against the US$77-shipped EXP GDC V6 inc 220W AC adapter. That's US$36 in favor of the EXP GDC V6.

Only discounting offered so far would be via removal of the 220W AC adapter. No cheaper shipping option has been offered.

Anybody want to weigh in on the matter? 'd like to see them lob US$20 off it, making it US$93-shipped to give it a chance.

I agree with you. I'd go for PE4C if its price were only slightly higher than Exp Gdc v6, because I trust BPlus more than any other retailer when it comes to eGPU matter. But here the difference in price is really a lot: about 1,5 times. If BPlus could manage to keep the price below 100$ I think it would be a fair price.

in the end bought a usb sound blaster omni from creative lab

a little upgrade from the internal sound card

Well done. It should also make a huge difference if you listen to music with decent speakers.

Exactly what Tyrant Eric said.

If you use an external monitor you could think about it.

If you use internal screen, the HDMI audio won't help you.

Hi TI member

I already have a eGPU for months. But since my laptop's internal speaker is broken, then I tried search any possibility to use a desktop sound card on my laptop too

Then I have any thought, that is it possible to use a eGPU and desktop sound card with a same time..? Then I googling, and found something interesting too : a dual m-pcie to pcie express adapter like this link :

Mini PCI Express to Dual PCI Slots Adapter Mini PCI E Riser Card for PCI Card | eBay

May be have you some experience with stuff like that to make eGPU work pararel with sound card.?

thanks for your help

I'm tired and maybe I'm saying something stupid, but... can't you use hdmi audio? That relies on the graphics card, as far as I know.

Voltage and power draw are very similar to other SB cpus tested, but I can't understand why mine can't go beyond x27. There is quite some headroom left. When I use Lynx it goes up to 4-core at x27 but uses 44-45W, so it obviously can't bear x28 with Lynx. But with Throttlestop Bench it should clock higher than x27, I think.

i'm newbie about egpu, i want learn from this thread

Nothing you need to worry about. But does your laptop have expresscard?

By the way, you really find anything you want to know in the first page.

Does the 16GB issue (100% cpu load) affect every notebook, or only the X230?

Exp gdc is 99$.

I think this pe4c is very interesting. Honestly, I think I'll go for this one, instead of the exp gdc. It seems there have been a few defective units of exp gdc, while bplus's support to the egpu community makes it more reliable (hopefully).

Those pillars make pe4c very stable too!

Looks like a power issue to me.

But try to set the link to Gen1, first. If that doesn't solve the issue, I'd try to redo the wiring of the Xbox PSU.

I'll hopefully get my setup running during the weekend, fingers crossed!

Let's see how it goes in the well-known grass scene!

By the way, BF4 seems to have a lot of fps drops for me as well.

You say with Exp Gdc? Or with PE4L too?

What are those pillars, anyway?

And I wonder how is it being switched on/off. Let's hope it switches on automatically when plugging the expresscard, like Exp Gdc does.

Looks promising, all in all. A bit pricey, maybe.

That 0$ EMS shipping looked a bit suspicious...

It's cloudhero, as usual. The product appears to be the complete set (with Dell DA-2), if you click the link to taobao provided in that page. The only thing is that it says 500g as weight...

Free shipping?
