Intel Pentium g860 Overclock?

post #1 of 4
Thread Starter 
Hello! I am new to this forum and PCs in general, I have built my first PC about a week ago.

I was never looking to overclock my CPU until now and I really need some advice.

I have an Intel Pentium g860 which I got from newegg, It was 60$ and for 3ghz of speed, It was a great component to my budget build.

Unfortunately, I believe its bottlenecking my GPU which is an EVGA GTX 650. I have reason to believe this because I get exactly the same AVG FPS on high settings as I do in lowest possible settings (Battlefield 3)

I have tried Overclocking my g860 but my multiplier is 'locked' at 30. And bus speed is about 99.97mhz.

I know that I cant increase the mulitplier past 30; Am I able to increase the bus speed past 99.97mhz to say 125mhz? Or is the bus speed also 'Locked'?

any advice would be much appreciated as I have hit a solid brick wall up to this point. smile.gif

The bus speed on Sandy Bridge chips like that G860 is essentially locked as well. You might be able to nudge it a MHz or two, but nothing substantial.

The rule of thumb for modern Intel chips (Sandy/Ivy Bridge) is that if the model number doesn't end with K, you aren't going to overclock it.

The G860 should not bottleneck a GTX 650.

how much ram do you have? If you have less than 4gb, that would be the bottleneck.

kifinas is right, a G860 is more than fast enough to feed your GTX650.

look at this benchmark, a G850 is on par with a Phenom II 955 quadcore
