It will scale higher with more cooling

[demonkevy666]

are you using just one 5970?

[Dr_Swizz]

Nice going Dumo! How do you like the Crosshair III? And what ram have you got? If it's Hyper, try running 6-6-6.

Thanks Zeus
I like this C3, first I though its hard to pump NB to 3.1Ghz+, but turned out it was my 965 0944 that have a problem.

I'm still stuck with 2X1GB GTR


@Memel, nice run there
Now, freez that 555 and go for 6Ghz+ and 4Ghz+ on NB

[Zeus]

My 965 C3 has a pretty bad CPU-NB too. Try running your D9GTR's at 7-6-5-15 or if they're not that good try 7-6-6-18.

[Dumo]

This one used to run @7-6-5 with 2V, but now slowly graduated to 7-7-7 and more Vdimm.

I guess its time to save for those fancy GT2

[gOtVoltage]

Nice work DUMO

A small Con with 555..
Ah whamo, you get itch and need deeper pockets for better Ram.

[Dumo]

Thanks GV
That GT2 is $200 a stick Gotta save more

Tricores are fun too

[FlanK3r]

memel: nice with only 1.35V...btw, u set wrong wprime (advanced setings, default is only one core, not 4 )

[ajaidev]

The x3 455 results are great looks, i hope someone uses a x4 635 for OCing on air very interested to see if anything has changed...

[Dumo]

The x3 455 results are great looks

Thats X2 555 with 3rd. core unlocked

[ajaidev]

Thats X2 555 with 3rd. core unlocked

lol and here i was thinking you got your hands on a yet to be released x3

Non the less the 550 C3 looks great for overclocking specially on air. Its a really strong processor for the price and gaming performance is close to that of i5 530.

thx

Nice clock Memel

Could you play with NB clock?

This 1004 seems to have good clocking NB with subzero cooling, probly better than my 0944 965

nice run, but.. :-D...

[Hazzan]

Awesome Dumo......

long time not see you...

[theoldtimer]

Great test results Dumo. This is my 555. It does unlock to quad but I haven’t had time to test it as a quad.



I installed the 555 in the crosshair III this afternoon and put it under cold water for a few minutes. This is the first over clock on this processor so I didn’t really do any tweaking I made a few basic adjustments in the bios then booted into XP @4400MHz. I had the vcore set at 1.6v+/- so I started running Super Pi and then after every SPi run I bumped the Ht one click using Asus turbo-V. I started saving screen shots above 4700MHz and this is the last one before the system crashed and rebooted. I think it has more in it so maybe when I get a chance I’ll test it a bit more.

[Dumo]

@Hazzan Thanks, its nice to be back. Salam for om Benny L

@OT Nice clocking with powerful H2O there
It can hold the load like my single stage. Can you bump up NB higher?

[memel]

nice batch 0008

[FlanK3r]

nice watter and 4770 MHZ !!
