without coldbug :)

Next weekend ..... 3dmarks ..... :)

What northbridge frequency?

What northbridge frequency?

3750MHz

At this sample you can easy see the importance of the core affinity mask :)

11_016 (affinity mask set to core 1)
11_147 (affinity to all cores)

[massman]

Problems getting over 4GHz or just didn't try?

Regarding affinity: you are correct. It seems that the Phenoms (both I and II) have problems running a single threaded application which causes the application to switch cores constantly. For superpi, it means that during your run, the process gets thrown from one core to another, resulting in a very bad performance efficiency.

[Hazzan]

nice result................ how about temperature ?

[G.Foyle]

Nice results :up:

You should be able to tighten tRAS and tRC more, thay have little effect on stability but help in pi.
I'd say the affinity problem is more Windows-related, not specific to Phenoms. It's the same on Yorkfields and Nehalems.

see picture in first post.

-190° C

Nicely done, Monteboy. Will follow you with my X3-720BE as soon as i get my mobo from RMA. Posted at 5.5GHz with ~ 1.65V, started loading Windows.... kzzzzzzt, condensation fried one of the phases :D

Nice chip , i whish you luck for the next session :)

windows boot with NB over 4400Mhz is no problem but stability when run spi1m
It was a compromise between Core frequency and NB-frequency :)
Next time i'll try to deactivate 2 cores ..... Perhaps 50Mhz more ....

We will see.....

[Bullet92]

Nice result Monteboy. Can't wait to see you in 3D action ;)

[Ming@s]

Very gooooooodddddd cpu.

:up:

[angoholic]

nice monteboy :) keep pushing it!!

[Lightman]

Very nice!
Awaiting your 3D scores :up:

[gaidin]

great clocks...plus bonus points for involving a toilet roll in the setup :D

[fatguy1992]

Awesome overclock there :clap:

Did you only need 1.525v? or that a glitch?

Perhaps the same happens for Athlons as well..? When I bench 1m I usually never see one core at 100%, it seems to run on both cores, but with 100% core usage in total;) Or is that something else?

cpu-z doesn't report the real voltage.
vcore was 1,8V ;)

[Benji Tshi]

Aaaa, really impressive. My 940 is only 5950Mhz ready for 1M...
Did you see any bug with NB ratios ?

[fatguy1992]

Ok thanks, that makes sense.

nice results monte!! these 955's really crank out the clocks

Thanks bro !

This Weekend 3dmark06 up next .....

This Weekend 3dmark06 up next .....

I'm really looking forward to it.... :yepp:

Good luck. :up:
