Specs: 4900MQ, 16Gb, 980m SLI. I recently upgraded my GPU from 780m SLI to 980m SLI. I am facing performance issues. I had very low passmark 43xx, I mainly play dota 2 and with my 780m sli, i used to get around 120FPS on medium settings. With the new 980m sli i am getting anywhere from 80fps to 30fps on highest settings. And FPS is not stable at all. If i even drop the settings to medium or low I still get the same fps. I got the latest drivers for everything and made sure that SLI is turned on. I am missing anything? Any help would be appreciated.

It seems NVIDIA is getting to ready to release two new mobile Maxwell GPUs in Q2 2016, the GTX 970MX and GTX 980MX. With the company already dominating the high end notebook market and 14nm/16nm next generation GPUs on their way like Polaris, the timing of this release seems a little odd. Both GPUs will be positioned as slightly more powerful than their existing GTX 970M and GTX 980M counterparts with increased CUDA cores, texture units, and clock speed while retaining the same TDP. In addition to the aforementioned, the 970MX has 56 ROPs vs 48 in the 970M while the 980M and 980MX have the same 64 ROPs. WCCFTech created a table which shows the differences between the new GPUs and existing ones: Model GeForce GTX 980 Laptop Version GeForce GTX 980MX GeForce GTX 980M GeForce GTX 970MX GeForce GTX 970M GeForce GTX 965M GeForce GTX 960M Architecture Maxwell Maxwell Maxwell Maxwell Maxwell Maxwell Maxwell GPU GM204 GM204 GM204 GM204 GM204 GM204 GM107 CUDA cores 2048 1664 1536 1408 1280 1024 640 Texture Units 128 104 96 88 80 64 40 Raster Devices 64 64 64 56 48 32 16 Clock Speed 1218 MHz 1048 MHz 1038 MHz 941 MHz 924 MHz 950 MHz 1097 MHz Memory Bus 256-bit 256-bit 256-bit 192-bit 192-bit 128-bit 128-bit Amount of memory 8 GB GDDR5 8/4 GB GDDR5 8/4 GB GDDR5 3/6 GB GDDR5 3/6 GB GDDR5 4 GB GDDR5 4 GB GDDR5 Memory Frequency 7008 MHz 5000 MHz 5000 MHz 5000 MHz 5000 MHz 5000 MHz 5000 MHz Memory Bandwidth 224 GB/s 160 GB / s 160 GB / s 120 GB / s 120 GB / s 80 GB/s 80 GB/s TDP ~150W 125W 125W 100W 100W 90W 75W Table Source: WCCFTech There's no word on what the price will be for these new cards or what notebooks will feature them but if I had to guess, I'd say the usual suspects like Alienware, Clevo, MSI and Asus will be among the first to have these ready.

Hi all, I had pretty good success with my GPU upgrade a few months back, although at the same time I realised my battery was on it's last legs. I bought a replacement that I had to send back as it was faulty, but now I have got a working one and it's running very close to the edge in terms of power draw. If I run any heavy GPU benchmarks, or even max out the CPU for any length of time on battery it will just power off in an instant. It's doing this both on Windows and Linux (the latter with the nvidia card completely disabled). I'm running Prema's Mods for both Bios and vBios. Is this something that other people have experienced? Shouldn't the power consumption be scaled back when running on battery just for this reason? Perhaps this is something the prema BIOS turns on/off, but I can't seem to find any other references to this. Any ideas how to manage this? Thanks in advance, Pete

Hi all I just bought two clevo mxm GTX980M for my alienware 18 r3, after install on my laptop and install driver, I found that there is no sli option in driver setting. After I review these two gpus in gpu-z, I found one 980M pci id is 1617, the other one is 13D7. I think this may be the reason that sli cannot be enabled. Anyone knows what should I do to make the sli option work? the 1617 one is from P770 ZM-G with g-sync build in.

Can the new Alienware 13" be fitted with a GTX 980M and 4980HQ?

Hey all, I have an old P180HM I bought in 2011 that I can play with. What's the fastest graphics card(s) I can drop in there? It currently has 2 x GTX 560M in SLI, a i7-26?? CPU (2.2 GHz max I believe) and 24 GB of RAM in it. I'm fine with the CPU, but wouldn't mind looking at different GPU's if I can get them somewhat cheap. What's the newest/fastest cards I can drop in without major changes to the cooling system? Thanks for any advice.
