some first AMD Deneb teasers on Foxconn A79A-S 790FX

[bingo13]

Thank You SoF Have you been able to talk to any one over at Foxconn about getting us A79A-s user an bios update for Phenom 2 940 cpu . I have
e-mail support and ask if there going to support the Phenom 2 940 cpu and they can not even tell me a yes or no answer .

The SO3 BIOS supports it fully as does AOD 2.1.5....

[demonkevy666]

Phenom II is rather special in this aspect.

It likes cold but it doesn't really like voltages (you need some to push, but cold, not voltages, will get you clocks)


So Phase and TEC+WC will yield really nice results, Phase on 5++?

1.344 volt stock at 3.0ghz and runs what like 28C idle ?

at 1.35 volts I'll idle at like 41-43C on 9850.

[SoF]

air stable was ~3.6-3.8 not tested too much. but I just made some really good experiences with wprime no Q6600 in hwbot can beat Phenom II...5ghz+ 9650 is needed to beat 4580 deneb

[Caveman787]

Whatd you ahve your northbride speed at for those runs SoF ~2300mhz like before?

I'm quickly learning to love you and iocedmyself for all these tid bits

[crazydiamond]

lol cpuz reports 2 diff vcores

[LC_Nab]

Really ???? The q9650 needs +5 to beat the phenom II at 4.5 ???? damnnnn !!!! >.< I can only imagine whats going to happen when the new boards for the phenom II comes out ... gazm !!!!

[SoF]

nb is 2585 mhz during this run - oh dear this mistake happened to me twice now with 2 cpuz and the same tab :wall: need to take myself some more time for the tests :p

[FatAlbert]

SoF, when you will can show us results ?

20.12 / 08.01 ?

interesting things you show and tell us

[Caveman787]

I def. hope that 20th NDA date was right, saw 4.2 claimed with an asus m3a32-T? on air combine that with 2.3ghz+ nb and nehalem will be in for big trouble.

[MonsterMash]

Since you told the max freq you reach stable on air, can you tell us also the max on water? Maybe with the required vcore .

Thak you so much for your work!

Thank you for the up-date on the bios .

This is of course if mainstream chips OC this well. Other than the early first batch.

[Titan7171]

im curious how high you can go on stock voltages to get to Windows desktop? 3.4-3.5ghz?? its usually safe to say 400-500mhz on stock voltages then from there you start raising voltages as you raise clocks...

If you look back,AMD's chip only clock better with time ,not worse.This is a general rule that also applies to intel.
AMD uses CTI(continuous transistor improvement) program and it worked great in the past.Look how well RevF clocked over time,then the B3 fixed stepping that now can reach even 3.4/3.5Ghz on QC/Tri/Duals etc.
If AMD continues with its CTI program,C3(AM3 Denebs) will be even better in OC/thermal regard.The sort of confirmation for this is the 95W max TDP rating of the 925(2.8Ghz) version of Phenom II.The 920,an AM2+ version,is rated 125W @ 2.8Ghz.

air stable was ~3.6-3.8 not tested too much. but I just made some really good experiences with wprime no Q6600 in hwbot can beat Phenom II...5ghz+ 9650 is needed to beat 4580 deneb

So i take it that was an 8.081 run

Sounds like 7 second wPrimes are definetly doable.

Sorry, I never use watercooling air and dice most of the time.

I think I did wprime1024m at 3.3 with 1.32V (undervolted) - 3.4 - 3.5 seems reasonable.

on vista intel and amd 45nm quads are close together with slight advantage for amd in performance per clock I would say. was real good to see yesterday and tomorrow I maybe have the possibility to test with a cascade

cool so Im going to say 1.5v is going to give us about 3.8ghz.......and pushing to 1.6v is going to just make 4ghz...........its going to be fun testing, I hope I get a good chip

[Maxxximum]

Ok it's the 20. of dec. So SOF MOVE ALL THAT BLACK S*** SO WE CAN SEE RESULTS

[Mav451]

Well, that's probably not as necessary, since he already said this:

no Q6600 in hwbot can beat Phenom II...5ghz+ 9650 is needed to beat 4580 deneb

Still I wouldn't mind seeing the actual numbers.

[SoF]

I have to correct my little bit too enthusiastic "5ghz+ 9650 is needed to beat 4580 deneb " - while I was comparing some days ago I did not notice all the XP scores on hwbot. With both, deneb and QX9650 under vista the advantage of the deneb will not be that huge anymore but still there is some for AMD in wprime I would say. I just returned back from my first little ln2 experience and gonna write a bit about it within the next hour...

Any news regarding you problems with 5x multi for HyperTransport?Can you verify cold bug issues are there unless you go to HyperTransport 1.0 mode?

One hour can't pass sooner .

first LN2 tests with AMD Phenom II in Germany by AwardFabrik and benchbrothers.de

With my friends from www.benchbrothers.de which have also one of the few Denebs in Germany I met today 120km away from my home to quickly test some Denebs with 25 LN2.
1. pic: left my system, right musicismylife (jens) on his one 2. pic: Masterchorch doing old school hardware benching with some "different" DICE cooling (no pics unfortunatly)


Normally I wanted to test 3x4870 and finally break 100k in 03 with full AMD but for some reason the score with my driver was terrible and trying to install the new one ended up with a totally messed up gpu driver. I also had this kinda think during G|C - starts to get on my nerves with thoose ATI driver *****



So I started LN2 the first time and when I did 5390 1m I thought it might be good to go out for a smoke. afterwards system was frozen and did not wanted to boot anymore. CPU was stuck to the pot for around 2 hours ^^


After some time in the oven I tried with 3-4l LN2 again and did following things:





Validations are finally working!!!! TY CPUz-Support

I had to leave then but the benchbrothers already did 5.7gig while I was almost leaving - think they will beat me easy There was one main difference to notice: I had to run HT 2.0 as A79A-S is missing an option to change this until now. in overdrive I can only use 6x at lowest - but even with that I could run -155°C at 1.85V without a problem. -160°C it freezed. jens and hoschi could run -195°C on destroyer with ht link 1.0 and 5x multiplier. problem with destroyer is the missing AOD and the aegis panel won't work good else this combo would have a lot more in it. for the moment I say A79A-S is the better foxconn board under cold for deneb. on air the destroyer seemed a bit better.
6 gig is definitly doable - I hadn't the time to go for 1.9V+ but I don't expect that much more from more voltage. maybe a better bios, different ram, lower htt (I was running 220 all the time for some performance) could improve stability but that's for next time only one thing is for sure: AMD loves cold again!!!

[Nedjo]

SoF do you have newest BIOS for A79A-S that recognize Deneb properly?
