Hi! This is my first time building a PC with nvidia cards in it and actually trying to maintain the PC and get the most out of its performance. I'm heavily modding Elder Scrolls Skyrim using 2048 x 2048 textures, SSAO, Super Sampling, etc, so I need this PC to purr like a panther.
So... since I'm not all too familiar with overclocking, and I have another question to ask, I thought I'd come to the best place I know of suited to answer... maximumpc.
I'll give you my PC Specs up front for reference:
2x Nvidia 560 TI (Frozr)
3.4ghtz Intel Sandy-Bridge (OC'd to 3.6 most of the time, 4.0 while playing Skyrim)
4x4gb RAM (16gb total) 1600 mhtz (Vengeance Corsair)
850w PSU (Corsair)
2TB Hitachi 7200rpm
1TB WD 7200rpm
6 fans, hooked up to the NZXT phantom, awesome wiring using the back space, and fan controllers maxed...
Since the two GFX cards are on SLI, I am totally confused as to which display port I am supposed to use? I want to use the HDMI mini port, which I do have an adapter for, but the adapter is flimsy and bends easily. I would rather just use DVI with an HDMI connector.... HOWEVER, whenever the PC first boots up, the BIOS and all of the other stuff isn't displayed. The display doesn't kick on until windows has been loaded? Is there anyway to change the boot-display? What display port should I use? I essentially have something like this:
Card 1: [DVI] [DVI] [HDMI]
Card 2: [DVI] [DVI] [HDMI]
Now that that is out of the way... my overclocking question. As I said, I'm trying to run Skyrim with a lot of epic enhancements. I've already enabled SSAO, supersampling, etc using Nvidia Inspector, but I find that Skyrim lags, particularly when loading new areas (the textures I reckon). When I turn off Supersampling or SSAO (ambient occlusion), the framerate drops completely disappear and the game runs on a smooth 40fps or MORE. I KNOW that two 560's on SLI should be able to handle skyrim with these settings, no friggen problem, so why am I getting this?
I guess my question is, how can I push these cards to do better. I clocked them up to 1000 MHz core, 2000 MHz shader, and 2250 Memory (around 36-45C stable), but that only partially weakens the frame drops to a bearable level. I want to play the game at a relatively smooth pace, with no sputtering or interruptions, and I built this PC to do just that.
Third question, in terms of SLI settings, what should be my dedicated processor?
Lastly, what OC program is best? For my nvidia cards I've been trying out MSI Afterburner and Nvidia Inspectory. For processor I use ASRock eXtreme Tuner.
Help and suggestions are both appreciated
