Sandy Bridge (Builds, Discussion and Random Shit)

Sorry for the double post but I need you overclock guru's over here :D

I'm a newb at OC'ing and am currently running at 4.5GHz (which isn't hard with a 2500k at all if even I can manage to run in stable)

But I'd like to try and push on to 5GHz since my cooling will be able to handle it...

So what I was thinking:

Bus speed set to 100, as default
Turbo multiplier set to 50
1.45V (vCore)

But what to do with the DDL Overvoltage and other parameters?


RJ's links have what you need to know. Ideally you shouldn't need to fiddle with anyrhing more than what you're planning on fiddling with, but as we all know, OC'ing can be fiddly at times :p

The only thing you should try to avoid messing around with is the VCCSA (System Agent Voltage) as thats known to kill CPUs fast. If its still unstable at high clocks, you could try overvolting thew CPU PLL (CPU Phase Locked Loop) but that may or may not work. Its essentially a trial and error process and sheer dumb luck beyond the 4.5GHz barrier.
 
Almost there!! One more week!

What mobo is that? I can tell it's a ASUS p8p67 but only 2 PCI-e lanes so that means it's not a Pro, EVO, or Revolution. I want to say there is a plain P8P67 as well as a LE version that have two PCI-e.
 
Here's the box. It's a standard P8P67 "REV 3.0."

And now for my newest mods. They help with increased airflow. ;)

^ A bubble fan? So that's water cooling and air cooling combined? Ingenious :wicked:
You must post pics of it in action .. or maybe better, a movie.
 
I shall fulfill your request.

The coke case is actually going to be where I set my computer on. I have carpet floors lol
 
Sigh.

I need a $30 Active MiniDp to DVI thingie.

Cuz my new Asus monitor doesn't have DP.
 
Got my computer built a week ago.

My build:
I had a $1000 budget, and built everything for about $960 or so.

Yes, it only *just* fits. Millimetres to spare!

Such a clean setup without the PSU.....

I went with a modular PSU, but it didn't really help the cable management, since I used all but two of the cables.

Is it worth the extra price difference from a i5 2500K to a i7 2600K?
I'm planning on using it for some gaming, 3d modelling (catia, proE), and perhaps some other simulation software and calculations.
Probably pairing it with 2x 6870, 8gb cl9 and a 700w psu.
Oh, and I tend to keep my computers for quite a while so I would like it to perform well for at least three-four years
Ideas on mb? There's a bundle with the Asus Sabertooth that would put it at a similar price with one of my other choices, the Asrock Extreme4

If you do 3d modelling then the i7 might be worth the extra price, especially if you are keeping the system for 3-4 years.
As for the mobo I recommend going for an Asus P67 board, since you'll be using 2 6870's you might want to go with a 800W PSU just to be safe, but I'm pretty sure it'll run on 700W.

Do you already own at least one of the 6870's? If that is not the case you would probably be better of with one high end current generation card, or if you aren't in a hurry to buy a computer you could wait for the 7xxx series of ATI cards to arrive.
 
No, I don't, I picked that up somewhere that two 6870's would perform pretty good.
The sabertooth is a p67 board actually.
I've also glanced at the 570, would that be a better choice?
I plan on getting the computer within the end of the month, but if the 7xxx are due soon, I might be able to wait :)

It depends on your applications and OS. nV cards have always been better with OpenGL than ATi, and nV drivers under Linux are MILES ahead of ATi's drivers.
 
I just built a new 2600K system a few weeks back.


2600K
Gigabyte Z68A-D3H-B3
G.Skill DDR3 1600 Sniper 2x4GB
640GB WD Caviar Black
Antec Earth Watts 500W
nVidia GTX 560Ti engineering sample
Centurion 5 case

I came from a Q6600 running at 3Ghz since 2008 and the difference is very much apparent. 2600K is absolutely awesome.


Not much to see that hasn't already been seen but when I get the cables tied up I'll post a picture.
 
Can anyone confirm if it is normal for the clock ratio to jump to 38x when using 1600Mhz or faster memory? My Z68 board started doing this after a BIOS update.

38x? isn't just the normal "Turbo" doing its job?
 
I think Turbo Boost only allows one core to reach 3.8Ghz if I'm not mistaken. If two cores are needed then they each can peak at 3.7Ghz, 3 cores each at 3.6Ghz and all four at 3.5Ghz.


After a bit of investigating via Google I have found a few posts from owners of both Gigabyte and ASUS Z68 mobo owners who have this exact problem. It seems like both Gigabyte and ASUS are enabling this "feature" in order to give their boards a better score with reviewers.:rolleyes:
