Holy crap 60W, that's really really awesome! This makes me wanna build one secondary small eGPU as well The pretty low-end 650-series will be obsolete after this. Moar sauce here: Tom's Hardware GeForce GTX 750 Ti review

According to our findings, a cooler CPU environment (no bottom cover/better heatsink etc) prevent this kind of throttling. For example my 3820QM could only handle x34 for a couple of seconds, then x33 for a minute, then settles @x32.5. I made some cooling improvements and now I run x34 for a full run of TS 1024M w/o problems.If you can lower your temps you will be able to hold x29 for much longer, but I don't believe you will go past x29 since you CPU never indicated to do this even for a short while.Also, I guess you are using a 90W ac-adapter?EDIT: You can clearly see that your CPU throttles @~93c, which also seems to be the limit for our 37XXQM/38XXQM. The Goal is simply to stay below ~93c.

Did your setup work before these PCI-power modifications? Did you perhaps change power-source as well?

This is where I might surprise you =) I can't say 100%, but my measurements tells me that it won't be necessary. Would you suggesting that rather adding a second pipe I should replace the existing one with a larger pipe instead? Sounds interesting! I have a new fan on its way right now, but to be safe I'd need something heat resistant material to put between the fan and MOBO just in case it would melt. Any suggestion? EDIT: The more I look at this mod the more I understand that there are no head room for a heat pipe on top of the fan. EDIT2: Well, the x220/x230 fan might actually be a game changer since it's built with copper housing, "in-built" heta pipes and 4-pin connector: A third option could be this: -Adding smaller HS+fan on heatsink: or this Of course this might be very hard to make room for, would probably require re-designing the 2560/2570p heatsink from scratch.

Hello fellow 2570P modders! I'm now working on a heatsink mod (and guide) for our system with the aim for improved heat dissipation (unlike earlier coin mod that only improved heat absorption), the goal with the mod is also to only work on the heatsink/radiator and keep the 2570/2560p intact. I want to do something similar to what @Aikimox have attempted earlier, adding a second 'sandwiched' heatpipe like this: (photo by Aikimox) My aim is to cut out a slot in the radiator and trim down the top of the heatsink like this (so the heatpipe can be inserted and therefore fit the mint system): So to my question: What is the best method to cut the slot in the radiator?

Ok I see, so you are wondering if HD6970 would work as eGPU: This card seem to be a "twin-GPU", which can be very difficult to fit in the PCI-space. You should probably look for a HD7970 instead.

If you want to have the best graphical performance, then NVIDIA GTX660 or newer is the best choice.

I was hoping that maybe Win7 unparking would help matching FPS in "Welcome to the Jungle" for Win8. There is no given reason Win8 should out perform Win7 AFAIK. Thanks for your info!

My understanding is that Win7 initialize 'core parking' by the default (which WIn8 apparently doesn't), which could be resolved by using Disable CPU Core Parking Utility I guess you don't happen to dual-boot win7/win8 to test if this is the reason for lower FPS? Apparently the unparking will gain significant performance in BF4, read about it here.

Really good temps, even though it's x33! What duration do you have for the test?

Hi guys! Have you ever used USB3 devices such as hdd etc? I mostly get the message "this device can perform faster..." and file transfers are really slow (USB2-speeds). This is regardless if connect a USB2 or 3 port. Also what drivers are you using? Thanks!

That's great news! This is going to be very interesting! Skickas från min iPhone via Tapatalk

I usually hot plug the eGPU during windows start-up logo, test this too. If nothing shows up this could be a case of a damaged cable.

Damn, I wish that controller board could be bought as spare part!

Wow, that went fast, good job dude! I'm very glad that I could help you.

Oh ok that sucks! Do HP cover the repair?

Damn you're officially the forums #1 graphics card hoarder from now =) So do you suspect that it was the fan mod that caused the damage of your mobo?

Wow, 5 min of high load and no Tj-temp, that's not so bad! Your Graphics score is very good, it beats my GTX670 with ~1100 points.

Yeah most of my problems have been PSU-related. I now run my GTX670 with a Dell D220P 220W AC-adapter, no more bluescreens/display driver resets etc. Of course using the DELL PSU requires some solder skills, so it's probably preferred to just get a 'new' ATX PSU instead. Please report back! EDIT 1: The most sensitive part of eGPU-system is the 5v feeding the PE4L, if your PSU is degraded (of age) this voltage can be dipping/ripple = instability. EDIT 2: Also, check the PE4L's expresscard-cable by lightly wiggle it during benchmark, bad cables is probably the #2 cause of failure. EDIT 3: #3 cause of failure: Different display card drivers can cause a lot of instability issues, if you know that you recently upgraded/downgraded them, revert back to your 'stable' drivers again.

Hell yeah! That's ultra setting gaming =)

@Khenglish : May I ask what kind of CPU benchmark scores you get with that beast of yours?

Other Test crash dump file: C:\Windows\Minidump\010614-11528-01.dmp This was probably caused by the following module: nvlddmkm.sys (0xFFFFF8800ABDEDA8) Bugcheck code: 0x117 (0xFFFFFA80069C04E0, 0xFFFFF8800ABDEDA8, 0x0, 0x0) Error: VIDEO_TDR_TIMEOUT_DETECTED file path: C:\Windows\system32\drivers\nvlddmkm.sys product: NVIDIA Windows Kernel Mode Driver, Version 332.21 company: NVIDIA Corporation description: NVIDIA Windows Kernel Mode Driver, Version 332.21 Bug check description: This indicates that the display driver failed to respond in a timely fashion. A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 332.21 , NVIDIA Corporation). Google query: NVIDIA Corporation VIDEO_TDR_TIMEOUT_DETECTED I reinstalled the driver, but the problem is still there... Please help! Hi there. The first thing I'd do is testing with another PSU, do some benchmarking etc. Tell me how it goes!

Hi guys. I need a GEN1 adapter and I'm wondering of someone is willing trade this for my GEN2 PE4L 2.1b-EC (150CM)? My work notebook can only handle GEN1-speed and I can't make changes in BIOS.

It's on its way to me now =) I expect some hacking and slashing to make it fit, if it succeeds it will help moving that heat more efficient!

I think you could run most of those games on medium/high settings. Do you have them to test? Lets do a theoretical performance estimation: From this database one could think that your eGPU (on internal display) should corresponds to 680M in mobile graphics performance? (By looking at the different 3Dmark scores) From this database a 680M runs: CS:GO @ultra ~128 average FPS and shows and Alienware 3720QM and 680M running different games (W.O.W. @9.55 ), looks pretty good?Let's say my theoretical measurements are correct then you have these choices: 1. Cash up for a gaming laptop with at least 680M and a 3720QM or better CPU. or 2. Keep your eGPU setup and enjoy even better performance on external display when you're not traveling. EDIT: would be awesome if you did some measurements when testing these games.
