I ordered an HP 6475b from Newegg recently with an AMD Trinity A10-4600m. Some of you may remember me from NBR (same username). I am noticing a dwindling presence at NBR and am a bit disappointed with the number of quality individuals banned from there. I don't care why or how, I just know that some very helpful and informative individuals have been booted (Tech Inferno Fan comes to the forefront of my mind), and it doesn't make me too happy. That being said, I will likely share my 6475b review here at T|I instead of NBR. I also am interested in giving this whole eGPU thing a whirl. It really won't matter to me personally since it doesn't fit my usage scenario, but just for the sake of mobile science and my own personal interest, I'll likely give it a whirl. I plan on updating my desktop GPU from a GTX 460 to a GTX 670 and will likely use the 460 in this experiment. So I guess, hello there, and hope we can have some fun together! So any input ahead of time would be greatly appreciated.

Here's my Lenovo Y500 purchased in December 2012. I have grown fond of this laptop and is quite impressed with it's gaming capability. It was not perfect though, the touchpad and keyboard had issues that would cause it to become unusable. I do not recommend buying this laptop until they fix this issue, if you guys are interested in this laptop, stop by the Lenovo support forums and wait until you see that the issue has been fixed. They've since replaced the Elan touchpad by one made by Synaptics but even some of the Synaptics touchpads are exhibiting some issues. Anyway, hopefully I've posted enough to have the rights to post pictures!

Hiya guys, Wow, it's been a while since I posted - although I have lurked for a good while now. Just wanted to say that everyone here is doing a really great job. I'm gonna try and be more regular so I hope to be able to contribute more and be a valued member of T|I.

Thanks guys. Tech Inferno Fan I may need your assistance in getting everything up and running but I'm willing to give it a shot. Maybe even invest in an AMD card, although I think I have an AMD Radeon <s>6750</s> 6670 single slot that was used in an older Shuttle machine I've got. Maybe start with that. EDIT: Correction it's only a Radeon 6670 not 6750. But good enough for a start. Brian - thanks for that info. Only time I'd like to take some stuff with me is if a site goes belly up, well or if I got banned like nando 4 did, and can totally understand that frustration. I look forward to sharing my experiences over here though. Seems like a good community of down to earth people. I'll be making my $100 "Elite Member" contribution here soon, as soon as I get around to poking money back into my PayPal account. BTW awesome rig you've got there in your sig! That's some serious muscle.

That is usually the stupid power saving features which have a mind of there own. Try going into your "Nvidia control panel" - "Manage 3d settings" - go to "power management mode" and select "prefer maximum performance" instead of "adaptive" and reboot!! Try that to see if its the power saving crap OR problem with the GPU. . **Be aware that doing this also keeps your GPU,s clocked at a higher speed even at idle, they do not drop to 135-300mhz like they normally would on adaptive** GL

This is what I got back from Masaharu @ BPlus RE: Gen2 compliance of PE4H. Still waiting for a reply about buying just the Gen2 cable ends for our users with existing PE4H 2.4a units. A Gen2-compatible PE4H 2.4a is definitely a better way to go. Well worth the extra $20 over a PE4L 2.1b for it's free-standing nature and interchangable ends. Consider too getting just a EC060A so you could plug it into a expresscard-slot equipped notebook too. First stumbling block I see is you'll need to contact BPlus to order a PE4H 2.4a + PM100A/PM200A. They only list a PE4H 2.4 + EC060A as a buy-it-now component. Going a mPCIe implementation on the Sony SVZ will be a less painful and far more cost effective approach than your previously planned MBPr + $950 netstor TBT enclosure. The netstor enclosure lacks the user settable PERST# delay (as was found on the not discontinued $140 TH05) needed to run a BIOS mode MBPr TBT eGPU installation.

Just wanted to say Hi and introduce myself. My name's Ratbag and I like to consider myself a tweaker. Not the "bad" sort of tweaker but the sort that just likes to tinker with stuff. Always taking things apart to see how they work etc. I think that's why I love computers because you can take and swap things around, mod things and do all sorts. Anyway, hi guys

^ what he said, so it's nearly impossible to get the board to like factory condition without some special chemical methods (that I don't even know the details of). However you can first install the chip and then hook up the leads anyway with small patches or wire/solder. I've done it a few times but not for vbios chips.

Possible, but don't get your hopes up. It looks like 1 or 2 will be VCC and GND, so you can find those somewhere else and solder directly onto the chip leads. For the others follow the trace if possible, then solder a wire to whatever component it connects to. If a trace starts out but then disappears down into the PCB, then you can remove the outer PCB coating to solder to the trace before it descends. I would suggest sanding if you can fit sandpaper in there. The coating is thin and will be removed fast, so I suggest no lower than 1k grit. Sanding is much more controllable than scraping. If you try scraping you'll almost certainly end up cutting the trace when trying to expose enough of it. Don't try melting the coating off with a soldering iron, I've tried that and it doesn't work. Only try this idea as a last resort. Even if you sand there's a fairly high chance of cutting through the trace. For traces you can't see at all, look up what the respective leads do on the BIOS chip to try to figure out where they go. On a sidenote, there is way too little pressure on that GPU die. By way too little I mean absolutely none. The paste should not completely cover the die like that after heatsink removal. With good contact all you should see only see a very thin haze of paste, with the entire die being visible. Temps will drop by over 10C with proper pressure.

The safe vbios in a P150HM are the Clevo 80.04.29.00.01 and MSI 80.04.33.00.24 ov 1.000v. The clevo vbios has a 3d voltage of 0.962v (stock voltage with this vbios) it allow an OC at max 954 core 2400 memory (may vary in function of the quality of your card) and give you a 3dmark score of 7600-7850 (in function of your cpu), this is the more safe vbios for your 180W PSU. Msi 80.04.33.00.24 ov 1.000v has a 3d voltage of 1.0v it allow an OC of 1006 core 2400 memory (may vary in function of the quality of your card) and give you a 3dmark score of 8000-8130 (in function of your cpu), at those frequencies and voltage, some games could overload your PSU (Far cry 3 in the LOST EXPEDITION level ...) you need to buy a wattmeter to measure if you could run a game safely with those frequencies and voltage. If you want to reach those frequencies safely, You Must also cool your laptop with a notebookcooler and do some mod on your backplate in order to give more fresh air to the gpu. At that moment the MSI 80.04.33.00.24 OC edition vbios (without OV) seem to have bug and give a voltage of 1.012v, so i can't advise this one on a P150HM. And yes ! Svl7 is a great man ... All others vbios will make your GTX680M unusable on your P150HM (the card will not be bricked but it will block the boot process, and you will be unable to restore a backup vbios unless you put your card in a P1XXEM laptop series) PS: make a backup of your vbios before flashing your card (nvflash -b backup.rom) PS2: Be sure to be in the latest BIOS for your P150HM, because i haven't tested these vbios in other environnement than EC/KBC V 1.00.13 & BIOS V 1.01.14 November 2011, Always update EC/KBC first. http://forum.notebookreview.com/sager-clevo/556299-clevo-bios-older-models.html PS3: If you got a Sager don't flash with a clevo bios and if you got a clevo don't flash with a sager bios (sager bios has custom EC/KBC that wasn't compatible with standard clevo bios, there is a risk of bricking your laptop).
