Hi all, I have just completed a new build and it just does not seem to be running as well as I think it should be. This is my second build I have done, my first build was done approximately 2 years ago and it went great and ran like I expected it to. I will list both my current and previous build specs so you know what I have to work with in case I need to compare parts.
CPU: AMD Phenom II x2 550 BE 3.1Ghz
Mobo: ASUS M4A79XTD EVO
RAM: OCZ AMD black edition DDR3-1600mhz 4x2gb
GPU: 2x Sapphire Radeon HD 5770 in Crossfire
HDD: WD Caviar green 500gb
PSU: Seasonic X-750
OS: Windows 7 Home 64bit
CPU: AMD FX-4100 3.6Ghz
Mobo: ASUS Crosshair V formula
RAM: OCZ AMD black edition DDR3-1600mhz 4x2gb(from old build)
GPU: XFX Radeon HD 6970 (Ver 1.2 without dual bios switch)
HDD(for storage): WD Caviar green 500gb(from old build)
SSD(for OS and games): 2x Samsung 830 64gb in RAID0
PSU: Seasonic X-750(from old build)
OS: Windows 7 Home 64bit
I built this new rig with the newer games in mind, as well as 3 screen eyefinity for games. As well as dipping into learning how to overclock once I had everything running right.
So far, the OS boots faster, but not quite what I had expected for the change I had made from HDD to SSD in RAID0. Overall Windows usage seems a little snappier. My main problem seems to show up in the graphics dept. Running Furmark 1.9.1 is worse than my dual 5770s I had previously. My dual 5770 ran 36 fps in 1080p benchmark, the 6970 runs at 30fps hitting about 70c. According to GPU-Z the gpu load hits 100% but the core clock only ramps up to about 580-600 mhz, not the 880mhz stock clock of the 6970. I decided to install Crysis to see how it performed with a high demand game. The core clock now ramps up to the 880mhz but the gpu load is at about 60%. With res at 1920x1080 and all settings on very high with vsync on it runs about 40-50 fps, not quite what I was expecting. I have yet to install Crysis 2 or BF3 as I want to get everything sorted out first. Both systems were running on the latest video driver from AMD 11.12. I tried rolling the 6970 back to 11.9 driver, but nothing changed. 3DMark11 ran 4365 on the old build, and about 4480(don't remember exact score) on the new build.
I am not sure if I overestimated my choice of components or not, but something just does not seem right. Any help will be greatly appreciated.
I ran Furmark and it ran just the same so I went back to the 11.12 driver. I loaded up Crysis 2 just to see if a newer game with DX11 would change anything. It hit 880mhz core and the load was 100% as well so I guess it is running like it should. I just figured with a 6970 I would get higher than 30-40 fps with high-res and DX11 packs on a single 1920x1080. Without the high-res and DX11 packs it sits around 50 fps in Crysis 2. I OCed the card to 900mhz core and 1400mhz mem and gained about 3-4 fps. Battlefield 3 on ultra is running around 40 fps. 3 screen eyefinity isn't looking too promising with this card on its own.
I was running eyefinity on my dual 5770s but it was too sluggish unless the game graphics settings were set to the lowest possible with 3 1920x1080 screens. Unfortunately the 6970 doesn't seem to be a whole lot more powerful than my dual 5770s I was running.
I am not familiar with your GPU but we are running slightly similar builds. I have 4 gigs of 1600 mhz, an fx-4100 oc'd to 4.5 ghz (stable w/ a giant aftermarket fan) and a M4A Asus mobo. I noticed your psu is 750, just a though but it couldnt hurt to upgrade that a bit. I have a 1000 watt psu and I haven't noticed any issues so far. If your gpu has programs you can download to mess with its settings try that.
