The teasing is over - Phenom II 940 Air, DICE, LN2 - OC round up!

Some good results.... Thanks for the results / review.

Its very simple, some would find acc easier, but alot of overclockers are bios overclockers, etc they like to play in the bios. The advantage of this is you can hold in the bios/dos and run memtest and find stable settings before going into windows blue screening and hosing an OS install.

Me personally I'm a bios overclocker......the only time I have ever used a windows OCing utility was to break the x2 3800 CPUz WR because I was having cold boot/cold bug issues.

SOF just out of curiosity did you have FUSION installed for any of the benches or did you optimize manually or are these all just unoptimzed runs.

[RaZz!]

Vantage?

People like you make it so hard to not buy one of these

obviously, they used winxp for their benches, hence no vantage.

thanks for the results SoF, much appreciated!

I didn't had Fusion installed, I used overdrive on my A79A-S but all benches on the Destroyer were done out of the bios except some minor ram timings in windows. A79A-S should have a bit more inside as if what I've showed until now. But I was too busy the last days to get testing another time

acutally we used vista for wprime and wanted to make some CFX but the scores where too low and then it totally destroyed the gpu driver (very strange issue i had a couple of times now). away from that I don't have a vantage version for offline scores that's the main reason

Very nice bunch of results, i have to take some more time to look at them more thorough.

One thing i fail to understand is that (almost) all results i've seen lately from Phenom II is they all had low HTT and lousy memtimings and/or lousy mem speed.

Is it harder on AMD to run 4-4-4 at let's say DDR 1000 or higher than it is on Intel?

acc is a bios option on sb750 boards, aod is a desktop overclocking app

First of all I have to thank SoF that he posted the results. I had not enough time since I was busy reviewing deneb for Planet 3DNow!

No, I don´t think so. We had a couple of results running 475 mhz 4-4-4 or 586 mhz 5-5-5.

In this first ln2-session we wanted to see how far deneb can go under cold and because of this htt and memclock was near default to eliminate this error source.

OOps shows how much I know, to many 3 letter abbreviation options

SOF that's good to know, that means there is room for improving all those scores with OS tweaks and bench specific tweaks, or using FUSION for those that have no clue how to tweak or what to tweak

[SoF]

Yeah there is still some room - I just grabbed 25kg DICE and tomorrow a friend from AwardFabrik will drop by with 50 liters LN2

We will go for some 3D and try to set new AMD 1m record With a bit luck I will recieve another 940 tomorrow we can also test. This will be an interesting week-end

Nice results and very nice review. Nice to see that you made a table of the results comparing PII to Q9650 and i7 920. But one thing I'm a bit curious about is the energy consumption when overclocked. On one page it says you overclocked to 3350MHz with as little as 3Ws extra but on the other it says it draws 30Ws... Also would like to know what cooler you used.

The whole bunch of benchmarks was done with Gigabyte GA-MA790GX-DS4H. With this board I was able to overclock to 3,350 mhz prime-stable with default vcore (1.39 volt real). Power consumption raised from 220 to 223 watts.

On the next page I tested different motherboards. I tested how far I can overclock the same cpu with default vcore. Then I lowered vcore with stock clock and tested power consumption again.

On the first diagramm you can see that I was able to run prime95 at 3 ghz with a setting of 1.25 (1.26 real) volt - 0.1 volt less than stock. That setting (193 watts load) saves 27 watts to stock settings (220 watts load) and compared to 3,350 mhz with stock voltage it is a 30 watts difference.

About one year ago I got a review-system from AMD. There was a Akasa-cooler installed (Akasa AK-876) which I still have in use. I don´t like it because mounting system is crap but it does work.

[SoF]

I am currently pre-testing for tomorrow's LN2 session. The A79A-S has a new highscore for 1m air and finally reached DDR2 1200! Also the 1066er divider finally works with one of my kits :

4050 MHZ - SuperPi 1m - 17.094s - 225 HTT- DDR2 1200 - 5-5-5-20-24 - Foxconn A79A-S



With RAM timings 5-7-7-28-31 like it comes out of the bios it is 17.125s. RAM timings are not doing very much in Pi but see what the NB clock does when you have it too low!!!

4050 MHZ - SuperPi 1m - 17.438s - 225 HTT- DDR2 1200 - 5-5-5-20-28 - Foxconn A79A-S



KEEP PUSHING THE NB SPEED GUYS!!!

[quintus]

Good Luck!!!
Will there be any 3dm01? that 70k is so low
thx

Ok, thanks for the explanation, maybe it was there in the text somewhere but my German is less than good...

Well with that information, it sure does look good for the Phenom in terms of both overclockability and power consumption.

[-= rtz =-]

Wow.. nice job and thanks for the major effort put into all this
I thought all the goodness is on page 1 but seems that was just scraping the surface and now we're getting to the real numbers

These new phenoms remind me of the old 1700+ T-bred B-s which could overclock to 2+ GHz when downvolted

Can't wait...Looks like you guys will be having loads of fun.

anyone know how I can tweak a HP compaq 8510p lolI won't be home for a few days, and need a tweak fix.

[SoF]

Ok report of the session here - too bad it wouldn't run as good as last time. Think the board was done after all this torturing
