i7-3930k 1k ppd more than i7-2600k

Both running at stock speeds.

At most the i7-3930k was 11k ppd more than the i7-2600k today. (32k ppd v 21k ppd)

i7-2600k is running Ubuntu 12.04
i7-3930k is running under VM with Ubuntu 10.10 on Windows 7 64bit.

Might try a usb boot to Ubuntu at the weekend and see what I get.


Any suggestions?

 

try ubuntu 12.04, and try the -lowlatency kernel if you haven't already

but a 50% increase [from 50% more cores/threads] looks about right from where i'm sat, any improvements SB-E has over SB will most likely negate the effects of the 3930's slightly lower clock speed...

and it's loads better than what i'm getting from my knackered 920

 

The computer must have been up to something as its now back up to 33k ppd on the i7-3930k.

mmmm back up to 101k ppd overall.

Still got a q6600 to build from spare parts. Just need a case.


Edit: no idea what -lowlatency kernel is. Can you explain? Tnx.

 

[all this is assuming a bog standard ubuntu install]

ubuntu installs the linux-generic kernel by default, from precise [12.04] onwards there's a linux-lowlatency [previously linux-rt iirc] kernel. It can lag update wise behind the generic one though.

type

Code:

sudo apt-get install linux-lowlatency linux-headers-lowlatency

to the console to install [or do it via package manager of choice]

it should ask you to choose which kernel you want to use during startup [if not you'll have to press esc during startup if memory serves], and you can check which kernel you're using the console:

Code:

uname -r

 

Cheers RedFlames.

I'll give it a go at the weekend.

 

I used to get around 25K @ 5 GHz on a 2700K. When I'm not benching with it, I get over 50K @ 4.6 GHz on a 3930K.

 

I tried to follow the overclcoking guide in the mag, but the vcore temp just kept on going up. I eventually rebooted and reset the bios when it hit 90°C.

Reading was from Asus AI suite II on my Sabretooth X79 m/b.

 

Hmmm... might as well go to the 4.7GHz route. I did try it out previously and it did work out 24/7. Although I am quite happy with the 30k ppd I am getting though. But, I would really want to get into the top 20 producers thingy before I hit one mil so shouldn't be too difficult.
