Got my Dell 7970m (ES) today... and so far it rocks! Native fan control, runs cooler than the 6900m series, and it simply kicks ass. It's pretty much plug-and-play, no issues so far, though I will need to continue the testing (and benching ). Only did a Vantage and 3dM11 run so far, with GPU and CPU at stock, Tess on, check it out, hehe: Confirmed for the Dell 7970m (part nr. 747M2) in the M15x: Fan control is working properly Sound per DisplayPort / HDMI is working GPU clocks and performs as expected Possible issues: The card runs slightly warmer than the officially supported cards, due to it's higher power draw. This also leads to less overclock headroom. The card works fine even if you have an i7 920XM in your system, but if you overclock the CPU too hard, the GPU voltage drops, resulting in a drastic performance drop. (This is actually not directly caused by a power limit due to the PSU... the CPU can draw as much power as it can get, but it seems that when the CPU draws more power than usual, the GPU voltage supply somehow doesn't get provided anymore with enough power, even though there's headroom power-wise, it's probably caused by the circuit design of the mobo). Things to do before changing the GPU: Download working drivers. At the moment you can either get the drivers of the M17x R4 from Dell, or the modified, but actually more recent (12.5) from "benchmark3d". Get some thermal paste, e.g. Arctic MX-4, or Prolimatech PK-1, or whatever you prefer, you'll also need something to clean the GPU die and heatsink, isopropyl alcohol or similar will do. I highly recommend using an ESD mat and wristband whenever working Get familiar with the upgrading procedure, respectively disassembling the system. Refer to the M15x service manual if you need help, or to this pictured guide which explains how to replace the GPU in the M15x. The upgrading procedure: Uninstall your GPU drivers. Make a power drain (Turn off your M15x, remove the power cord and the battery. Then press and hold down the power button (Alienhead) for about 10-20 sec. Remove your GPU - Here's a little guide with pics in case you need some help. Clean your heatsink, if necessary replace the thermal pads with new ones. Make sure the 7970m has the correct backplate on it. Insert your GPU, make sure that it sits properly. Apply the thermal paste, and attach the heatsink. More to come.
I've been trying to test out this card on Battlefield 4.... it runs anywhere from 100+ fps on medium settings, to 30fps during performance drop situations. While looking at MSI Afterburner i noticed the card would go from 850mhz base clock/1200mhz memory clock, to 450mhz for one or two seconds and then jump back up to 1200mhz again afterwards. During this dips and spikes is when my fps would go way down. Is this because i need to undervolt the card as perhaps the Cpu is hogging power from it or something? I read Slv7 saying something about the m15x motherboard circuits distributing power the wrong way or something like that. I am wondering if i should undervolt the card so that it will not battle with the cpu over power, if that is the reason for the spikes and dips, and how i would do that. I installed and played neverwinter nights 2 yesterday and for some reason that game seems more demanding than bf4. I have an i7940xm cpu, and a 7970m gpu that came out of a dell m17x. Catalyst 14.12, and on highs a gpu temp that can reach 80c, and a cpu temp that also can reach 80c. Help would be much appreciated. Thanks.
