I think he meant that he needs to make a vBIOS for the 2nd card, which is called a slave card in SLI.. Should be fine.. Give Prema some time.. Sent from my LG-H811 using Tapatalk

i have tested not only furmark.in 3d mark firestrike the temps about 88 degrees and higher on gpu 2.after then i tested furmark.now i have already flashed back to alienware bios and now the fan is working.

Using furmark is considered to be a no-no. Use the heaven benchmark instead. Sent from my HTC One using Tapatalk

Switched thermal paste to Coolaboratory Liquid MetalPad. The heat builds up much slower now. I can make it through 30% of a TSBench 8thread run before I touch 100C. Basically ran into the dissipation bottleneck. During benches like 3dmark the CPU doesn't even go over 87C. 3dmark11 physics score increased by about 400 points, though firestrike remains pretty much the same, lol. Neither are putting 100% load on the CPU. I'll be drilling holes for airflow when I can get a dremel. God, i wish I had two heatpipes. I'm pretty sure I could max frequency on this CPU if I did. 4703 FS P6854 3dmark11 Also finally touching 4.05GHz (not touching 4.1 because of the 99.7 BCLK I think).

Your system has 2 flash chips. The 2 smaller outimage files are the exact image for each chip. The biggest one is the one with them combined. Use the biggest one when flashing with FPT. I have not seen a laptop that had a PDR region, so don't worry about it.

Have you checked your cooling? It could be that the vents are clogged so you're not getting the cooling you need. A sharp blow of air into the vents when the laptop is off is sometimes enough to declog the vent and could be a very quick way to fix the issue. Another option (if your temps are going up extremely fast when you do anything) is that your thermal paste or heatsink are not functioning correctly so I would resit your GPU with new and decent paste and check that the heatsink is properly in contact.

Yes, the vars in the link. I set them as you suggested, var 0x1D4 set to 0x0 and var 0x1D8 set to 0x1. Oh, I noticed I can also boot to the efi setting utility by copying the EFI folder to my recovery partition. No more USB stick required. When setting Internal Graphics to Enabled without setting them as default, the system boots but gives Code43 on the Intel HD Graphics driver. Once set to IGFX default, everything is peaches. Wow, 3.9GHz across 4 cores appears to be stable but gets hot FAST. After 5 seconds of TSBench 8thread 1024 i get immediate throttle down to 3.5GHz... which is still pretty nice, considering the limitations. EDIT: With CPU OC'd to around 3.9-4GHz average and GPU OC to 1200 from 1050MHz core, these are the new scores: P6813 3dmark11 4684 3dmark FS The overclocked r9-270x scores 2512 points in Furmark FHD benchmark, about 70 points below a stock 7970. Considering it's based on a 7870 Pitcairn, that's quite a bit better than expected. This is on a Gen1 link. I'm drooling thinking of a GTX-970 + PE4C v3.0 combo, but considering how broke I am, and that this whole entire setup including the monitor cost me around 600$... I don't think I'm allowed to complain. I think it'll be a LONG time till a TB solution can be had at similar performance / specs for similar cash.

@Simurgh5, @Mark, @josho, @soularchive and other 15” Nvidia dGPU equipped MBP owners. I got an idea to modify the web driver package purely for your external GPU, so that dGPU (such as 750M) will never utilize the web driver. This will not take long.

I'd definitely choose RocketStor. Actually I might order one. If it turns out to be stable with R9 AMDs, I see no reason to use AKiTiO. EDIT: I thought first the price drop was in Europe too... hmm, have to rethink about this. It's likely that the 4-pin molex is for providing power to the TB board, not to PCIe board. We know that AKiTiO works as back powered but it's risky to assume the same with this product. I don't know what would be the most safe approach to try straight 4-pin plug connection. Multimeter tests may reveal something, but can we be sure?

It's a pleasure to announce that after all the teasing we finally release the modified vbios for the Nvidia GTX 780m. This is a result of a close collaboration between @johnksss and myself. There's a lot effort and many hours of work and testing behind this, and the result is a vbios which will allow you to release the power of the GK104 chip on that card. To put it in numbers, you can now break 10k GPU score in 3dMark11 without any hardmods or extreme auxiliary cooling. Also an very big thank you @chiefule for sending me his card just so I could mess with it!! That's just hella awesome!! Really appreciate it! Without this there would most likely be no slider control. You can grab the vbios at the end of the second post of this thread. I recommend being reasonable when using those sliders, you have been warned. Flash and use at your own risk.

More stuff exclusive for T|I users, voltage mods: All the vbios listed here are attached at the end of the post. ******************************** Nvidia 800m series: Nvidia GTX 880m (8GB version only): 'OC edition' -> unlocked overclocking limits, voltage adjustable, power target adjustable, optimized performance at higher clocks Can be used for all current 880m (Clevo, MSI and Dell). Nvidia GTX 870m: 'OC edition' -> see above Nvidia GTX 860m (GK104 variant): 'OC edition' -> see above. Refer to the file name to know which version is suited for your system. NOTE: Only for the Kepler version of the 860m. Silly Nvidia started giving different GPUs the same name. ******************************** Nvidia 700m series: Nvidia GTX 780m: 'OC edition' -> unlocked overclocking limits, voltage adjustable, power target adjustable, optimized performance at higher clocks Can be used for all current 780m (Clevo, MSI and Dell).

For P1xxHM based systems I recommend only using version 80.04.29.00.01 !! Some users reported issue with other vbios versions (stock or modified, doesn't matter). EM users make sure you're on the latest BIOS / EC same with increased 3d voltage ('OV') -> refer to the file name (Same warning as above applies to P1xxHM users). ----------------------- K3000m: (Nvidia) K3000m - 80.04.3A.00.07 'OCedition' -> higher software overclocking limit Should work on all K3000m, unless you got a board ID mismatch. (HP) K3000m - 80.04.33.00.2E - 'OC edition' - > same as above, but probably the better choice if you use a HP machine ----------------------- K5000m: (Dell) K5000m - 80.04.33.00.35 - 'OCedition' -> higher software overclocking limit, stock 3d clocks 758MHz It's Dell but should work on all K5000m, unless you get a board ID mismatch. ----------------------- GTX 670mx: MSI 670mx (1.5GB) - 80.04.5B.00.A5_'OCedition'_rev00 -> higher software overclocking limits, tweaked performance at high clocks.
