overclocking i7 for max Gflops?

post #1 of 29
Thread Starter 
Hi,
Right now i have a i7-2600k overclocked to 4.7Ghz stable. But I was wondering what ways I could increase throughput and Gflops.
I know with the 2600K you can't really up the FSB much but are there any other ways to gain more Gflops and throughput?

This is primarily for an Intel vs AMD battle, since AMD has Hyper Transport to up the amount of data that can be transported.

pump your 2600k higher also RAM speed/timing will have some effect on GFLOPS

With my old i7 930 I got more Gflops with hyper threading disabled. Also higher overclock and faster RAM speeds.

you always get a lot more with HT disabled.

thanks you guys. anyway to get it higher than 4.7Ghz? what is the max voltage I should give it? I was kinda unsure as a lot of things change from C2Q to the i7. It would be nice to go higher.

Max vcore is 1.52, I've run some benches at 1.55v though.

thanks guys, I'm not at the computer in question right now.. I'm at school. but I'll definitely up the vcore a bit. Right now I'm around 1.4vcore. so I still have a bit of head room. maybe I'll be able to hit 5ghz+

With the 2600K it doesn't suck the max voltage all the time does it? I think I read that it throttles back when not under full load?

I know it used to be better to cut that out, but I thought that I read in a guide that in most cases it was better to leave it on? is that right?

Keep c1e and speedstep enabled, and use offset voltage.

how exactly does offset voltage work? what does it offset from and how do you know when you've reached the max voltage you should apply?
