DIY eGPU experiences

[masterjumong2012]

hello everyone


i finally manage to get a some time to rerun the benchmarks with Physx set on CPU on my computer and without further ado, ladies and gentlemen let me present to you the results


my computer is call Acer Extensa 5620z-4801 and i upgraded and modded almost all parts on it. its current specification and other stuff are as follow
-Core 2 Duo T7500 2.2Ghz 4MB L2 Cache 65nm MEROM CORE
-4GB DDR2 800
-320GB Hitachi 5400RPM SATA II



the kit i have is PE4H 2.4 + EC2C(expresscard) running at x1
-Galaxy GTX 460 GC 768MB
-Dell 2007WFP 1680x1050(external monitor)
-OCZ StealthXStream II 500w



NOTE: I am using TweakForce 266.58 Desktop Drivers


result using Core 2 Duo T7500 2.2Ghz

Spoiler :

and now using Core 2 Duo T7500 @ 2876.1Mhz

NOTE: i TME-Unlocked and used throttlestop to lock my multiplier to x12

Spoiler :

masterjumong2012 looking at your overclocking results, it looks like you locked your PCI-E clocks and only overclocked the cpu and ram. There is probably an option to also have your PCI-E scale with your cpu clocks to get 20% more pci-e bandwidth. It's not a guarantee that everything will be stable though (my ethernet chip goes unstable at 4% OC, but I just say screw it and use wireless).

i tried upping my PCI/PCI-E clocks by about .5(the smallest possible increment) but as soon as i select setfsb, it would result in BSOD or my computer would lock up

i also raised my cpu voltage to the max available and tried upping PCI clocks without overclocking my CPU but still no luck


i suspect that i am getting hit hard by bandwidth limit because i can play mafia 2 and gta iv on other laptop(Toshiba A665) that only has Core i3 350m 2.27Ghz with no turbo boost but optimus enabled but on my laptop it is lagging and stuttering so badly


i really need to find a way to increase my bandwidth because overclocking the cpu has very little performance improvement


edit: i also disabled the oboard HD audio on the Nvidia card as suggested

Well i'm planning to buy it, and i have the specs same as you...

Thanks for your info, to make sure about it before buying, BUT did you try it on external monitor? optimus with transparency rendering will affect on cpu load... (especially the igp is well integrated @ 500mhz.

Thank you guyz!

@nando4

Why should we consider buying this laptop if you can build a cheaper desktop? It's not that portable... But nice ideal for traveling!





P.S: Sorry for the nooby questions i asked before, but when "masterjumong2012" showed his results i admit that the chance that it will work is 90%...


Thanks a lot! (saved my wallet!)

I see the idea as that you can game at home, but when you want to unplug the graphics card, you can use your computer on the go.

I think for a lot of users (like myself) who own only laptops (personal and those issued at work) this is a great way to get high performance gaming.

In particular, the work issued laptops (I have a HP 2540p) have great CPUs and maxed out RAM, but terrible GPUs, usually those Intel integrated chipsets. With Optimus enabled, the DiY ViDock is a lifesaver

I have no intention of buying a desktop, ever. I can pay $300 or less and get decent gaming performance out of what I have.

I have a question. Is there anyway to get the DIY Vidock working through USB ports? And is it possible to use it with a sound card?

No. USB's bandwidth is too limited. It would also have to be going through adapter drivers and the USB interface before being able to function like this.
