***955 Unleashed***

[chew*]

I was lucky enough to get my hands on one of these 955's early and whip up a review for launch day.........enough chit chat lets see the star of the show and what it can do.....

First I'd like to note I swapped to the latest publicly available bios on gigabytes site for the ddr 3 board.

Special thanks goes out to MsiMax who helped out alot with the LN2 results.....He has quite a few of his own results if he can find them

AIR results
Gigabyte 790FX and FXT
AMD Phenom II 955
Pc Power and cooling 750W
ATI 4850's
ATI 4890s's

I saw a lot of shots like this and I personally disprove of them, not real world at all..........Yes you can do 4 gig on stock volts..........however lets see what it takes for true stability........



Prime stable, true stability at its best, seems the 955 is definitely a cut above the rest.......



All around bench stable



All around Bench stable with the NB cranked up



I decided to test out the IMC and do some ram clocking....and whoa

The IMC is tuned well for low latency ram and will do far better with slower speeds and tighter timings.



Some more ram clocking although I admit I didn't put as much effort into this one.



Max all cores for opening MS paint and saving while oced



Max cpu-z all core validation ( I finally broke that magical 4.5 on air )



Phase change results
Gigabyte 790FX and FXT
AMD Phenom II 955
Pc Power and cooling 750W
ATI 4850's
ATI 4890s's

All around bench stable



Some 3d benching 2x 4850's



Some 3d benching 2x 4890's



Max all cores for opening MS paint and saving while oced




Max cpu-z all core validation



DI results
Gigabyte 790FX
AMD Phenom II 955
Pc Power and cooling 750W
ATI 4850's
ATI 4890s's

All around bench stable



Went for a max speed in PI 1m



Ran some 3d03 for fun on DI w/4890 single (I think this is 5th on the bot)



Ran some 3d06 for fun with 4890's in xfire



Max all cores for opening MS paint and saving while oced



Max cpu-z all core validation
seems this got rejected but no loss 6.4 gig passed......


Ln2 results
Gigabyte 790FXT
AMD Phenom II 955
Pc Power and cooling 750W
Gskill ddr III 1600 @ 1700+
ATI 4850's
ATI 4890s's


All around bench stable



Max PI 1M I could pull with a budget set of ram



Some Pifast



Some everest



Max all cores for opening MS paint and saving while oced



Max cpu-z all core validation



And for the grand finale

Single card 4890 second place 3d06 in the world ( card is still on stock air )



2 x 4850's X fire World Record ( cards unmodded and still on air ) I forgot to bring the cpu speed back up with K10 stat, speed was 6.1gig as you can see according to 3d06 ( we were booting at this speed ), bug with gpu-z overclocking cpu when you open it causing a crash forces us to downclock.

Summary.

It has been a pleasure working with the 955 Retail and in all shapes and forms has exceeded the clocks and performance of the ES chip I have been working with.

I'm quite sure there is even more potential in this chip just waiting to be unlocked and looking forward to benching with it some more in the very near future.

very full review chew* i'm going to get some DICE runs in tomorrow but i somewhat doubt i will even come close to you good runs just wish you had a smidge bit better ram for some of the tests. hit me up in a PM and i will see if i can find you some good HCF8's or D9JNL


mind if i post my results in here?

[Tom128]

Nice, hoping to get a 4Ghz 24/7 clock on water when I get mine. Seems feasible!

[Movieman]

Very nice numbers!

[cdawall]

Nice, hoping to get a 4Ghz 24/7 clock on water when I get mine. Seems feasible!

it is temps under 40C load should allow 4.2ghz 3D benchable, 4.0ghz stable

Very nice start Looking forward to these chips, hope to have one next week on LN2.

[overclockedamd]

OH ya baby. Cant wait to get my hands on one of these. Got dozens of pounds of dry ice available from a local shop.

[_d_]

thanks for very full review sir

[Akrian]

Holy , AMD strikes back =). Now I'm tempted to get one of those. is it possilbe to pull 3.95-4.0 Ghz on AIR for 24/7 ?

[Oldguy932]

So pretty much this 4.1ghz phase cooled one isn't really going to be that fast compared to most people now. I guess I know what I'm getting the week after finals

[bro20000]

I cant wait to get mine now! Nice Review!

[msimax]

the 955 are awsome little buggers

All set on ram, dont let those gskills fool you.

I benched with them for a reason to give a real world view for most users and what they can expect to get or better.......

It seems I've run out of email addreses to validate my air 4.5 validation........Used the wifes one to many times.

Will get it sorted in a few.

[tbone8ty]

is it possible for these NB speeds on my older Asus M3A32 mobo? (sb600)

nice overclocks chew.

im excited!

[Akrian]

Chew* , what Vcore would you suggest to use on those sweet 955's for 24/7 ? ( I couldn't find the official specs on AMD site )? I mean looking at your tests , even if I reach stable 4.oghz on air it will take awfull lot of Vcore volts to do the trick.

[dennilfloss]

Thanks for all the charts.

The initial Canadian price sucks! Better go down in a couple of weeks.

Incredible Work. Comprehensive results on stock parts. Outstanding.

I have been waiting a long time for this part to launch - it's a great node and the NB has huge potential at cold temps.

Congratulations.

Really depends on chip but 1.520 seems to be the max needed for 4gig....It took me 1.575 to get my 940 stable at 3840mhz..........I think it can handle the volts as long as you cool it properly

[msimax]

some of my pi work using win7

[dinos22]

wow very nice guys

[Akrian]

since I'm a bit tight on my PC budget, after getting all this expensive INTEL crap last october ,I will be stuck with my old MA32 Deluxe ( wi-fi) edition. It died on me couple of months ago ( or that was my CPU 0_o) anyway I'll RMA it tomorrow and hopefully all things will work out .

[richierich]

wow

[chew*]

I just wanted to add I ninja'd this into my max cpu-z validation........take a close look at HT speeds.............

Yes there is no issue and you do not need to underclock HT one bit.......there is no spoon and there is no coldbug.............the limits you create are within yourself and nothing more......

[SoF]

wow very nice write up chew great results and sure I now wanna have one

[Oese]

w00t i have only one question: why are these online shops in germany so damn slow with making this available to ME :wall:

Hope i'l see one here on saturday or at least next week....
