This the specs of my m18xr2
3rd generation intel core i7-3740qm processor ( 2.70ghz 6mb cache, up to 3.7ghz w/ turbo boost 2.0)
24GB 1600mhz ddr3 sdram (2 x 4gb + 2 x 8gb)
1TB 5400rpm hard drive, 32gb msata minicard (caching)
AMD radeon(tm) hd 7970m 2gb gddr5 crossfirex(tm)
can i add one more amd radeon 7970 to make it dual..
Can i add 512 ssd? (Which is better raid or single)
Adding another video card would be a great upgrade, you could crossfire both 7990's. For this upgrade, a 330W ac adapter will be necessary.
If you're planning on installing an SSD, a Raid configuration isn't necessary. Install the OS on the SSD, keep the HDD as storage and leave the mSATA accelerated.
I believe it's a smart decision, send us an email to firstname.lastname@example.org with your service tag and contact info. We’ll help you to get the right parts for your rig.
