I think my i3 2120 is throttling my computer.

post #1 of 40
Thread Starter 
Straight up, I bought this rig on a tight budget. I ended up going with an i3 2120 3.3GHz Sandy Bridge that is pretty decent at what it does.

I have:
NZXT GAMMA Mid-Tower Case
ASRock Z68 Extreme3 Gen3
Intel I3 2120 3.3GHz
2x Sapphire HD Radeon 6850s Crossfire'd
8 GBs G.SKILL Sniper RAM 1066
OCZ Vertex3 90GB SSD
Western Digital 640GB 7200 RPM
Antec 700w PSU

- 5 Rosewill RFA-80-BL fans are placed around the case in optimal cooling positions and controlled by an NZXT Sentry-2. Case is generally around 20C.
- The GPUs are modded with ArcSilv 5 paste and two aftermarket fans with additional cooling from side panel fans. OC'd to 850/1075 at stock voltage. 40C~ Idle | 60C~ Full Load
- The CPU is cooled by a Corsair H60. 30C~ Idle | 40C~ Full Load

From the looks of everything on my end, I should be able to blow games out of the water. I can run Just Cause 2, Super Street Fighter IV, League of Legends, and a few other games without issue at 100+ FPS

But...there are games like Battlefield 3, The Sims 3, and Fallout: New Vegas that make my computer stutter pretty bad.

I've tried disabling Post Processing in the games and forcing them through the Catalyst software. It works a point, but still runs pretty badly. Not like 10- FPS, but 30~ FPS.

I know OC'ing the i3 can be kind of rough, but I did manage to get it up to 3.6GHz stable. I didn't see a noticeable performance difference, so I changed it back to stock.

I'm just 100% stuck on why my games aren't running as well as they should.

EDIT: Forgot to mention that I usually run two screens. I read that it might cause issues for some games. Unplugging/disabling my second screen didn't help performance at all.

You're running

2 Screens

&

2 GPU's


You need to get a 4 core CPU, end of.
Shhh!

Shouldn't run 2 cards on an unoverclockable i3. Is there anyway you can return them and just grab a 7870?

Nah, most of the stuff is the remnants of a previous rig. The CPU and Mobo are brand new.

The problem right now is that I really can't decide what I want to upgrade to. I need something that I can OC, and that won't hit my wallet hard. Looking around websites, that seems borderline impossible.

Quick question: Would it be better for me NOT to run CrossFire on this CPU?

Yes. I would try to sell the 6850s and just buy 1 single card. Is ur ram running ddr3 1066?
