Hello to everyone, first post here. I want to ask your opinion on my system.

  • System:
    • Hardware
      • HP ProBook 6560b
      • Core i3-2310M
      • 8GB RAM (4+4)
      • iGPU Intel HD 3000
    • Software
      • Win 10 Pro 64-bit 

  Additions:

    • Hardware
      • nVidia 760 GTX GAINWARD Phantom
      • EXP-GDC v8.4d Express Card version
      • 650W ATX PSU
    • Software
      • Latest nVidia and Intel Graphics Drivers
      • nando's DIY eGPU Setup 1.3x
      • DSDT Editor + Compiler pack

 

No big issue till now, very happy to made a self soldered HMI cable that allow me to work in GEN2 ExpressCard mode (GPU-z tell me PCIe x 16 2.0 @ 1x 2.0 during 3dMark and Fraps benchmark)

 

  • Performance
    • 3Dmark 06
      • 10143 (SM2.0 4079, HDR/SM3.0 5030, CPU 2507)
    • 3Dmark (steam DEMO version)
      • Firestrike 3886 (24.81 FPS Gt1, 20.92 Gt2, 8.7 FPS Physx, 7.9 FPS Combined)
      • Icestorm 22488 (98 FPS Gt1, 98 FPS Gt2, 71 FPS Physx)

 

Unfortunately i have bad performance on benchmark (except Firestrike) if i made a comparison with other systems. I don't know if Opt1.2 use pci-e compression through HD3000 or is just a CPU limit that i reach. All test are made on internal lcd only (that is my focus now).

 

Does anyone idea why? Any suggestion?

 

Follow system screenshots and pics

Here's a 2570P with a i7-3520M + GTX960 + 376.88 driver . It scores a 3dmark06=20825 , doubling your SM2.0, SM3.0 results and nearly with a double faster CPU. 

It's difficult to isolate then what is causing your reduced performance but tentatively you may be correct. Nvidia may have disabled PCIe compression on HD3000 equipped systems which has a dramatic affect on DX9, particularly 3dmark06, results.  Consider I saw 3dmark06 results > 15k with a core2duo CPU.

Hi Metallus,

Want to make a home made EC->hdmi cable for my exp gdc 8.4 (unstable @1.2), how did you build your own?

Thanks

Hello Nando

thank you a lot for fast answer. If it could be a driver related problem, do you think that doing some DDU + downgrade i'll find my driver? Or trying to mod some notebook driver instead? How can i check if compression is really enabled or disabled? Just only with benchmarks?

I have read somewhere that without battery plugged on the system "seems" to be without compression and with battery plugged "seems" to run fine. I have no battery (used laptop) but one is on route, i'll try and let you know if something change.

Do you have a suggestion of which Nvidia driver version try to install?

 

@ehcoboy. I bought an high quality HMI cable for TVs (the one with ferrite  near connector you can see one in my picture) and i cutted it short enough, soldered on a ExpressCard32 connector (not very nice to see but effective) and now i have with problematic EXP-GDC 8.4d, a full stable PCI x1 @Gen2 (2.0) speed. I made a lot of test and i'm 100% sure that i'm on 2.0 because if i force system to run 1.0 i see my scores goes below numbers i posted before.

Some soldering skills is required but with googling you can find pinout and with beep tester you can find EXP-GDC pinout and solder it

Bye all

3dmark06 is the best indicator of PCIe compression being engaged or not. Keep in mind the compression has a large affect on DX9 titles. DX11 sees little performance benefit from it. Your 3dmark11 score is comparable to older core2duo desktop systems as seen here.

If you absolutely want the PCie compression then the best way may be loading the oldest compatible driver you can find and re-running 3dmrk06, looking for a noticable jump in performance figures.

Ok thank you a lot. I have GTX760 i'll try to use Win8.1 driver 2014 - 2015 years and see. I use my system for some old games (like CS:GO  so dx9 and i need little FPS boost) and new one (trying to use with BattleField1, but maybe i'll replace i3 with i7 with higher GHz if i am lucky)

I'll post relevant results here for future!

Bye

Little update on my test with older driver:

  • Nvidia Driver 331.82:
    • 3Dmark 06
      • 12173 (SM2.0 4952, HDR/SM3.0 6665, CPU 2541)
    • 3Dmark 11 Performance
      • n/a - too old drivers?
    • 3Dmark (steam DEMO version)
      • Firestrike (n/a - too old drivers?)
      • Icestorm 29365 (152 FPS Gt1, 136 FPS Gt2, 66 FPS Physx)

 

New driver:

  • Nvidia Driver 378.66:
    • 3Dmark 06
      • 11666 (SM2.0 4651, HDR/SM3.0 6380, CPU 2493)
    • 3Dmark 11 Performance
      • 4855
    • 3Dmark (steam DEMO version)
      • Firestrike 3692 (25 FPS Gt1, 21 FPS Gt2, 8.3 Physx, 6.46 Comb)
      • Icestorm 22473 (98 FPS Gt1, 98 FPS Gt2, 71 FPS Physx)

I downgraded also Intel HD Driver from 15.28.24.64.4229 (9.17.10.4229) to 15.28.23.4101 (9.17.10.4101)

Boost with older drivers in dx9 is noticeable, unfortunately i want to use latest driver for game compatibility, so i hope that the new i5 i just found (should be compatible with my laptop) will increase dx9 performance.

maybe i will try a Nvidia 350.xx driver but i dont think that i will have new good results, so sad that there is no a way to force Opt compression back on HD3000

 

Bye!

@metallus, the difference in results between the 331.82 and 378.66 is minor. Pls consider redoing the 3dmark06 benchmarking when the i5 CPU arrives.  The Optimus x1 compression 3dmark06 results being heavily influenced by CPU performance.

@mettalus84 Did you also have a unstable Gen2 connection on EXP GDC? And you are saying a home made cable solved the problem? Where did you get the ExpressCard34 connnector from? Also where can i find pinout for all that? 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Until mettalus84 responds, consider the following to reduce EMI noise and signalling spikes/interference:

- isolating the PSU for the eGPU to it's own dedicated power outlet/point
- do not have any USB devices attached to your system, particularly the EXP GDC
- place aluminium cooking foil over the EXP GDC cable
- set SLIM LINE switch to Ultra, which supposedly disables the EXP GDC USB port per here
