Phenom II X4: Northbridge @ 4,5 GHz

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 :D

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????

Amazing work keep it up!!

32m, 32m at that speed Sam :)

:eek::eek::eek:

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 :up:

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

great work guys:clap::clap::clap:

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


I look forward to U11:up:

Seems like Kyosen had a backup :D

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

OK. Whose next with 5GHz NB :p:

Seriously, amazing clocks both on NB and CPU :eek:

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.

Incredible results there, congratulations :clap:

impressive work as always! :clap:

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

seem like a low voltage for nb at 4.0ghz.

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 !!

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

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

Awesome results! :)

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

.............:up:

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 ?

NB 4.5G:eek:
...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:D

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

you need to keep a ratio 1.8Ghz NB: 3.0ghz core. you need more core or something ?
is this because NB/L3 cache is bigger/improved then Agena ?

Only tried LN2 :D

Thanks, I'll try AM3 next time

Thank you kyosen. My CPU is engineering sample and using latest AMD 45 nm process so there will be soon improvement in retail parts.

I'll install XP and try to break 11 seconds in spi1m this weekend.

what
no 32M SuperPi :D :up:

Not my game ;)

unreal nb and amd spi. Good job :D

Ok I did today very quick testing today with Windows XP:

Best SuperPi 1M result I managed to run was 11,234 seconds which I believe is new AMD SuperPi 1M world record with 0,001 s difference to kyosen :D

http://www.ripping.org/benchmarks.ph...i=1M&cpuid=AMD

http://plaza.fi/s/f/editor/images/ph...pi1m_11234.png

Cooling: F1 EE + LN2
Vcore: 1,8125 V (bios)
NB: 1,45 V
DDR: 2,24 V
HT: 1,24 V
Motherboard: Asus M4A79 Deluxe
OS: Windows XP + SP3

Tweaks:

- Silver theme
- Turn off not necessary processes (printer spooler, etc)
- Realtime
- Affinity CPU 0
- Close exlporer

I'm not very good superpi tweaker so I count on high MHz on CPU & NB :)

(good tips are always welcome) ;)

Congrats on new WR Sampsa!

Just 0.001s faster than previous WR :eek: :ROTF:
BTW why so high latencies on mem?

Alright, now pull out the helium out again already and break into the 10's :D

Your efficiency is definitely in the upper echelon here, looks like the 4GB is helping out. What's funny is that the Vista score is pretty damn good already in it's own right, faster than I'dve expected.

:eek2: :shocked:

very nice congrats...

maybe a tighter mem timings will help ^_^

hope to see 32m soon...:D

worked really hard for that 1m record - congratz sampsa and keep pushing :D

Very nice.

Btw. I think that OC was better on Vegas due motherboard, not chip. ASUS and DFi really arent comparable (Im saying that cause I have ASUS 790FX mobo and also tried DFIs 790FX - same chip, same cooling difference about 250MHz..).

A clean XP setup seems to help you a lot. Your efficiency is near Kyosen's (a tad higher), so I reckon you're not as bad as you think you are.

Can the NB go even higher or are you near it's limit?

Wow, that is one nice NB clock!

Great to see. :up:
Who would have thought to see an AMD "chip" running low 11's in SPi1M a year ago. :)
(And this is not really a "bench" well suited for AMD CPU architecture in the first place).
Now I find it fun to bench AMD again. :cool:

Sampsa
how about Super Pi runs on Windows 7 Beta?

Why?

awesome work Sampsa , you did a good job

keep pushing it

0.001s difference!?...don't be kidding, Sampsa:)

Now I've reached 11.156s...
...I could even observe 11.125s, but failed to get the screenshot:(

I found that NB 4.5G is also available for mine with higher NB voltage.
I could get 1M, 8M and 32M run with Vcpu-nb: 1.6500V setting.

And also I could reach NB 4.6GHz;)
It was not stable for 1M run, but enough for 128k run.

I'll try to get 11.10x in next time with higher NB clock:)

kyosen, good work! :)

I'll try higher Vcpu-nb and 5 GHz next time ;)

great work Kyosen-san

dewa dewa

SuperPi is quite a bit slower in Windows 7.

Great run there Sampsa, the only tweak i can think of now is tighter memtimings and more MHz. :D

Phew, you guys don't go step by step, but leap by leap it seems. :D :up:
The AM3 DDR3 variants will take you both sub-11s 4sure (do I hear sub-10s?!).
