Here's my system:
OS: Windows 7
Mobo: GIGABYTE GA-X58A-UD3R LGA 1366
CPU: Intel i7 950 (no overclocking as of yet), Xigmatek Dark Knight cooler
Ram: 8gb G.Skill Ripjaw
Video: ASUS 4870 Radeon HD
Power supply: Rosewill bronze 750W
For a few months, this pc was a powerhouse. No matter what game I was playing at the highest settings and resolution, I could always have a browser with a lot of tabs open and a music player, and there would be no lag or any mess or problem.
It started around the time I got a second monitor for the system though I think the problem is independent from the second monitor. Anywho, I mostly play Starcraft 2, and I started to notice brief periods of intense cursor/game lag (noticed in singleplayer as well). I have also noticed this occurring even in lighter applications like photoshop. With ATI Catalyst and Windows Resource Monitor, CPU usage barely gets above 20-30% and memory sometimes goes up to 60%. For the Graphics card, highest temp i've seen is 85 degrees and around 40% activity.
Oh also, I don't think i notice this as much anymore, but along with the cursor lag, I would hear strange pops/clicks/laggy things in the audio, usually while playing starcraft.
Also, I've messed around with resolution and stuff for games, and I can't really tell if there's a huge difference or not. The cursor lag is only occasional (maybe once every game or so I'll notice it).
I'm happy to provide any other information although I'm not the most computer savvy (my brother helped me put this one together), but I'll try my best.
1st, Just Checking: Are you running the 64 bit version of Win7? If not you can't really use more than about 3.25Gb of RAM which will really slow you down if you open several programs and have games running too. (RAM above that size can Not be accessed / used by a 32 bit version of the OS)
The i7-950 uses triple channel memory. So, three DIMMs or six DIMMs. How many DIMMs do you have installed and what size are they? (2Gb each is the most common...)
The 4870 runs pretty hot, but, at 85C you might be starting to throtte back the GPU
Ah, nice MB! I like GigaByte & ASUS the best, good stuff...
You want the sticks in the Blue slots. Start Closest to the CPU. I know you Only have 2 stick at present but be sure they are in the 1st and 2nd BLUE slots.... then went you get you last stick fill the last BLUE slot...
Post a note when you get the third stick install. And we can assure the board is running at a full 1333..... (if you check CPU-Z on Memory tab "DRAM Frequency" will read :
- 533 Mhz (for 1066 RAM speed)
- 667 Mhz (for 1333 RAM speed)
NOTE: might be a touch higher as some motherboards automatically tweak things up Just a bit. MINE reads: 668.2 Mhz...
