Phenom II X4: Northbridge @ 4,5 GHz

[Sampsa]

Hi,

I tested one of Phenom II X4 ES chips I got from Las Vegas event. I used new Asus M4A79 Deluxe motherboard (790FX + SB750), ATI Radeon HD 4870 X2 in CrossFireX configuration and Windows Vista 32-bit.



First I ran 3DMark05 CPU running @ 6,0 GHz. I pushed northbridge a little bit and it had no problems running @ 4 GHz 3DMark05 stable.



Next I adjusted HT and memory speeds little bit and broke 44k. This CPU is not as good as the one we used in Las Vegas, it did 6,15 GHz in 3DMark05 with LN2 (different DFI 790FX motherboard)



Next I started really pushing northbridge and got it up to 4,5 GHz.. Spi 1M stable



Best 1M I ran was 11,263 seconds (in Vista). I didn't use any tweaks, just real time from task manager. Sub 11 shouldn't take long.

I have another CPU waiting, maybe it is little bit better.

wow ! kewl !

11sec for amd cpu is awsome.

thanks for the pics.

WOW!!!!!!! Great work man. Which bios are you using for M4???

edit: What's the real vcore????

[sdumper]

Amazing work keep it up!!

[CCC]

32m, 32m at that speed Sam

great job sampsa, u guys never fail to amaze me...

tighten up those timings, and hopefully ur new cpu would be better to break 11s. again, amazing job

nice work Sampsa! 3dm05 really loves these PII's

oops, looks like the Finlanders are joining the SuperPI party...
(while we are still struggling in getting a sub-12)

great work guys

[CAL930]

WOW!!
I have tried the CPU of 4.3GHZ, but 4.5GHZ does not have that I looked


I look forward to U11

Seems like Kyosen had a backup

[Hazzan]

awesome result sampsa.... yesss so far I try that board easy handle higher NB 3 GHZ but you can get 4.5Ghz awesome

[Lightman]

OK. Whose next with 5GHz NB

Seriously, amazing clocks both on NB and CPU

Can you say Sampsa what volts are required for 4GHz+ NB?

[Sampsa]

Can you say Sampsa what volts are required for 4GHz+ NB?

I used LN2 and 1,4125V for 4 GHz.. little bit more for 4,5 GHz. Remember this was ES chip with AMD's latest 45 nm process.

[LowRun]

Incredible results there, congratulations

[subaruwrc]

impressive work as always!

[demonkevy666]

well then 6ghz core and 6ghz nb shouldn't really be a probelm

seem like a low voltage for nb at 4.0ghz.

[FlanK3r]

nice Sampsa...How good was on AIR this ES on M4A ?Only 1.55V at 6GHz+ ...

God is not a DJ

God is an overclocker Nice work !!

[SoF]

wow awesome, waited sooo long for some Pi from you - can't wait for 10.xxx in XP!

[DeDaL]

Sampsa, very good setup and 3DM 2005
If it strong in 2005, maybe it strong in AM3 too.

[SeLecT]

Awesome results!

Very nice clocks and NB-speed! Wait for the new CPU

[dread77]

If it strong in 2005, maybe it strong in AM3 too.

[Astennu]

Damm nice speeds !!

Are you running Vista x64 bit ?

And did ACC help you clocking the cpu higher ? i was trying to get mine higher by using ACC but instead it was less stable when using -2, +2 or +4. And how much volts did you need for the CPU and the northbridge ?

[kyosen]

NB 4.5G
...great work, really promising results

NB 4320MHz is my best so far, but I couldn't get 8M run at this NB speed

And...I have no backup result, still these are my best...
...don't be reserved, Sampsa

[Hyperhorn]

<-- Was fighting for 3 GHz NB with X4 920 @air the day before yesterday
Great NB-clock, awesome result!
It's ambitious, but I'm sure we'll see sub10s when AM3 + DDR3 is there. Golden chip is necessary ofc..
