i7 920 @ 4.2 with 7990/7970 to 4930k - Marked difference!

Been putting my chips as far as I can since my first overclock on a Cyrix 586 ... never lost one to overdoing it yet.

I'm probably just being overly cautious tbh I usually am and especially with a chip costing this much... :p

I've found with CPU overclocking you tend to get loads of MHz for very little voltage increase and then hit a wall where you need lots more volts for very little increase, I usually just stop at around the wall and try to get things stable. I've always been more concerned with temperature and stability rather than all out performance.

What Cinebench score do you get at 4.7ghz out of interest?
 
End of the day ocing is personal thing just like our rigs you take it as far as you are comfortable like most I want descent performance without endangering my chip as it has been said their not cheap lol
 
It's practically impossible to damage something these days though, even if you wanted to. They put safeties and throttling in everything.

Even if you put 1.6v through your brand new Haswell, it would just turn itself off once it got warm (pretty quickly).

920 @ 4.2 is exactly what I'm sitting on. My own personal roadmap is to get another 780 but going from the OP I don't think my 920 would keep up.

I was hoping to last until the next gen CPU's however, 5770k or whatever they'll end up being called.

I'd get the second 780 and see how you go as that will still net you a load of performance and tbh for me it was only a couple of games really but it's gotta start somewhere :p The overall effect with 2 nvidia cards may not be a problem at the end of the day .....

What RAM do you have?

Had not run that yet so just downloaded it and got (Ram is 16GB DDR3 1600 @ 8-9-9-24-1T) ..

And this is DDR 2400 @ 10-12-12-32-1T that I had waiting to be installed (May well be returning it as increase is small over the 1600 stuff above but got some more testing to do to decide!)

Yeah I guess :)

This 920 has been a bargain, CPU/RAM/Mobo was only like £220 from the MM and that was like 4 years ago :p
 
920 at 4Ghz here, looking to go 4930k myself, and sli 780Ti.

Very nice to see people feeling a change.

I'm also using the TRUE cooler for my 920. I bet we had very similar systems! I've deliberated for a while if i should just go for the GPUs (780Ti) and forget the rest for now and hold out for later CPUs

but I'm also wanting sata3 for my raid M4s, and I'd like USB3 too, and faster boots and just generally want to move up because... well its what we all do :P The 920 has lasted me an age, I got it just as the D0 Steppings came around and it feels great even now. I just cant hold out any longer. I want my next purchase to last the same kind of time (4 years) as i'm going to uni in september so will mostly be broke. A big upgrade now while I'm working, should see me through.

Looking forward to any RAM results you post, I've been deliberating between 1600 and 2000+ kits. OcUKs quad channel high speed ram choices seem to have become very limited :/

Had my 2700k running without the fans spinning on the CPU cooler. Accidentally unplugged the fan when changing graphics card. No idea how it survived and booted into windows, but it froze and I smelled some burning. I thought the chip would be a goner :eek: but it runs fine I think lol.

I'm running 16GB Samsung Green 1866mhz 9-9-9-24 1T I bought it back when it was cheap. :p

Do you get the same score as me at 4.4ghz? (1180-1190) it doesn't seem a big difference to 4.7ghz but that might just be how Cinebench is.

Interesting, 1158 with same RAM settings ... need to have a play!

What OS ? I am on Win 8.1
 
I'm on Windows 7 (fresh install).

Motherboard is Rampage IV Gene I don't know if that makes a difference? maybe yours has less aggressive sub timings or something.
