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

[SoF]

Hi,

maybe it is good to start my own "teaser collection" on my good old Foxconn A79(A)-S and P05 Bios as I just passed 32m 210 HTT 3.9 gig on air.

3.3 gig undervoltet and running wprime1024 (it passed but so you can see load temps)


Wprime1024 with only +0.1V on 3.8gig quickly - time is not too bad I can tell you


4 gig 32m without ACC and some voltage. So far I remark a good scaling.


4 gig 1m 1.44V CPU


235 HTT gained 0.5s compared to 20x200 with 1.800mhz nb


To be continued

DICE screenshots



quick 32m here - it goes higher until 1.7V. for more LN2 would be good, this likes cold as hell. I am running against a wall around 5 gig but still awesome



5 gig Validation DICE

Hmm SoF, is 4Ghz @ 1.44V using ACC?

[SoF]

no all results are without ACC as it is not working yet (will not boot as soon as enabled in any way) hope a new bios will fix that

[flopper]

4ghz amd, not everyday you see that.

[SoF]

finally I can raise HTT a bit up to 235 seems to gain some more performance from that specially in Pi.

ACC is useless.... unfortunately.

[Lightman]

Thanks to SoF now we know that Phenom II @4GHz will do SuperPi 1M in less than 1 minute .
Also we can certainly say that SuperPi 32M can be calculated in less than 1 hour on above mentioned CPU !!

Do you have more teases coming shortly??

[jonspd]

nice sub 20 sec 1mb super pi

looks like around 17-18 sec to be exact between the 20x200 and other setting

Hmmm, low HT walls or did you not test higher? If that's the wall it doesn't look good for locked multiplier chips but at the expected pricing it doesn't really matter

[TheBlueChanell]

Any possibility that 790GX is gonna be better for HTT overclocking, than the 790FX cause of the smaller process?

And to any body's who's actually sat down and overclocked one of these, does the HTT work in a similar fashion as the X2's and Opty's, or is it similar to Phenom 1 where you can't do much in the way of HTT?

SoF, can you please (if you have time) try to OC with HT only? It would be interesting how far you reach, I was planning on getting the locked 920...

[SoF]

so far it maxes out ~240 htt. primed yesterday shortly (~30min) 3.6gig with 1.4V fine.

[merkk1]

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 .

My 790GX MA790GP-DS4H would max at 240 on my 9950, The M3A79-T Asus will go well above that..So maybe the locked chips still look promosing on the right bios/board..

[Rammsteiner]

Pretty awesome regarding temps. What cooling was this on though? I mean... air cooling can still be anything

Without ACC 4Ghz, very nice. Maybe PhII indeed doesnt benefit from ACC but looks like we'll have to wait a bit more to be sure.

There isn't a HUGE price difference, grab a 940 or 945 when it arrives

Oh, ya,. i remember your post you were hitting higher HT reference then me on my 790GP. I just couldn't get more then 240 stable....

@SoF

Why you don't upgrade your bios? your current aren't old?

[SoF]

i am waiting for some infos about the bios. they seem to already have something anyway p05 does fine with my one

[azraeel101]

Well I gotta get a motherboard for it too, I don't know if I'll afford the 940..
The fact that I'm from Romania, a third world country where hardware is way overpriced doesn't help either...

[SoF]

4050 1m - time is getting really good for AMD now with some more MHZ that could give a little surprise

Can't see the pic, and no link to large..or not working..

You are hinting at the increase in speed per clock that HTT overclocking is giving you ?
When you increase HTT and leave northbridge multi at a fixed value,you increase NB/L3 clock speed and decrease the latency of a very large and already very effective L3 cache significantly .This is the source of the better results with higher HTT.NB clocks could be a not so secret "secret" weapon .If it can net even 5% over default,it will be awesome,but i guess it can be even better since this time it should even scale better than Agena in that respect.
