Phenom II 6 GHz+ OVERCLOCK

[charged3800z24]

what happens in cod4?



Best wait for real reviews, Honestly doubt p2 will be slower than p1.

HT and NB are slower and of course ram etc ....That is most likely the cause.. since that game see's no impromement requardless of CPU..GPU bottle neck there..

[Titan7171]

wonder what evidence Intel has that AMD used a "tricked" chip.......if they end up wrong about that they are gonna look desperate doing theres.

they already look desperate.....see its cause and effect..........They have to do it cause AMD did it.

Reminds me of the line from Ironman


AMD did this in a cave........with a box of scraps!

A 3Ghz Opteron should be faster than the Q9650 if I reference SharkyExtreme. :O

However... SharkyExtreme used different resolution and different graphics card.

Those UT3 and winrar results show some hope. Still let's wait for phenom with 1066 ram and 790GX chipset. I would say it's a significant difference. I expect the NB frequency to be at 2400mhz (agenas had a bit more Hurz too than barcies if I remembered correctly)

Exactly. The 35% increase in UT3 is a very good result!

Actually the northbridge on all Barcelona chips at least for the single socket 75W ACP ran at 2ghz, which is faster than all Agena chips except the 9850 and the 9950. But I do agree that we should be seeing the nb on the 920 and 940 at around 2.4-2.5ghz. Hopefully since the chips work so much better under cold now we can see some massive overclocks to 3ghz and beyond on the nb combined with the 5ghz+ overclocks. You can bet that I will spend my time working on a 1:1 overclock of them both when I get the 940 hooked up to my vapo.

I ran a few comparisons here. I though those shanghais all come with 2.2GHz NB?


Their 9950BE result looks like mine with mem at DDR2-800 CL6 unganged. So if shanghai/deneb scales similar to my 9950be the deneb result at 3GHz mem DDR2-1066 CL5 would be 32,5% faster, means ~2024KB/s which is 16% faster than the phenom at those speeds.

I beleive it is running at 1000mhz (i guess 2000mhz effective).. due to chiptset limitations.. The desktop solution have faster support, which is why Agena can run 2000mhz(4000mhz effective) with 950/9850 and 1800mhz(3600mhz effective) will all other models. If this server can 2000mhz(4000 effective) then the new AMD server chipsets won't be as much of an improvement as stated by AMD. Although, that 2.7ghz chip is supose to have a 2200mhz (4400mhz effective) with new AMD chipsets that will come out. we can assume that Phenom II will share this same 2200mhz if not more based on this being what the high end Opterons hold.

Or am a I way off here?????

Partly, only the HT speed is limited to 1000MHz not the NB speed I used 1GHz for my 800-CL6 benches above. BTW: My results under winxp 32bit are higher than those vista 64bit results.

What I find fascinating is that Mighty Intel feels threatened by piss-ant AMD. As many have observed here at XS, no cpu-z, wprime, etc. screenshots were permitted at the AMD demo. We only have word-of-mouth on PII 940 results. Yet, Intel feels threatened.

I think Intel feels there is a real chance of a repeat of the ATI/Nvidia debacle that occurred with the release of the 48xx line of video cards. No doubt in my mind that Intel is going to revise i7 pricing down in December to counter aggressive pricing by AMD. This is great news for all enthusiasts!

Very interesting comment. I believe the word of mouth by select people are leading them to believe AMD definatly has a nice chip on it's hands or they wouldn't be bothered at all. When AMD revised the Phenom series with the 50's series CPU's Intel didn't bat an eye because word of mouth showed the Phenom 50's series wan't that stellar, but the Phenom II has them very worried. AMD said that they are VERY confident with Denebs/Shanghai and the chips surpassed their expectations. So word of mouth + confident AMD= A worried Intel.

Pricing wise I have always loved AMD and I am glad Intel may have to revise the prices of their over priced chips. All the Pro-Intel folks should THANK AMD for things like this. We can expect a ton of Intel folks shifting to AMD soon. The changes AMD made at their company will pay off VERY soon!

The difference in rated wattage between Shanghai and Deneb makes me wonder if Deneb will run NB at 2.4G or 2.6G.

[demonkevy666]

well AM2+ board can run NB up to 2.6ghz AM3 can run it up to 3.2ghz.

each cpu should be able to reach 2.6ghz but not all of them do.

I have the same assumtion.. but we will have to wait and see.. Some leaked specs show 2200mhz..but makes me wonder why the 2600mhz ready on the boards if AMD did not plan on using it..

Overclock headroom maybe? I've seen some people hitting CRAZY NB speed with just a standard
Phenom.

Where did you get this info?

I wouldn't be surprised if the AM3 boards would support the HT 3.1 standard as well. http://www.hypertransport.org/defaul...Specifications

[Oldguy932]

I ran my nb all the way up to 2.75 at 1:1 with one of my 9850's under cold. So I was at 2.75 cpu/2.75 nb/2.75 htt. Its just as fast at memory intensive situations as a 2.9cpu/2.3nb/2.3htt. Not completely sure about the memory settings, probably all done on the 400mhz divider because it was before I got the ram I have in my systems now. The nb on current phenoms does amazing under cold compared to air. The same 9850 on air could do 3.0cpu/2.4nb/2.4htt relatively stable, not completely because it was my SB600 board and I haven't done any testing since I got my SB750 board. I'll be picking up parts for a new system at the end of my winter break assuming that's still when AMD is releasing them. Completely free tuesdays and thursdays will be pretty good, maybe I can find some ln2 to use in the room, my roomate shouldn't mind

Yeah, it has to be with a fan.

Only 90 watt or less processors can be passively cooled.

The P2 940 is 125w TDP.

Therefore it would fry if it didn't have a fan to get rid of the heat specially overclocked.

[informal]

sorry but i don't understand

was the Z600 fanless or whit fan ?

It was with a fan.

[informal]

whit fan

What? You expected a 4Ghz overclock on a 45nm chip(loaded with crysis and far cry 2) to be handled with a fanless passive heatsink??Are you serious? Show me a yorkfield or even worse core i7 at that clock that can work fanless under load...Yeah,the result would be 2 melted boards and probably 2 dead chips(or maybe they'd have survived due to thermal protection kicking in).The temperatures would literary be in 100+ degrees Celsius range.

Please be serious...

phenom II have 1/20 intel leackage.
it's more cold.

No it doesn't have 1/20 "leackage"(you meant leakage,right?).
Please don't post nonsense here.You heard someone said some aspects of AMD's 45nm process have better characteristics than intel's 45 nm hk/mg and now all of a sudden AMD's process has 1/20th of the leakage.Btw that is not correct:

The transistor drive current for AMD's 45-nm devices is much lower than that of the Intel HKMG transistors. But power consumption is quickly becoming a high priority for server chips. AMD's transistors exhibit very low channel leakage. Our transistor benchmarks indicates that leakage current is less than one-third of the value measured on AMD's 65-nm process. It's also significantly lower than the Intel 45-nm HKMG process. In fact the Ion/Ioff ratio for AMD's PFET is nearly 10 times better than that for the Intel PFET.

Even though AMD's 45nm SOI process indeed shows some great characteristics and the chips run very cool at higher frequencies,it's very unreasonable to think 4Ghz(overclocked and overvolted!) chip can run on a fanless cooler with only a passive heatsink...
Like I said,be serious.

FIXED!

No offense,but don't "fix" my posts and then quote me like i said it(even though you just left one part out).Put it in " " if you like.
BTW,what was not correct in the part you left out?

[informal]

Lol yeah,"attak" me for what?For showing how clueless you are? What you are writing isn't making ANY SENSE.You understand that?
BTW,i would like to see that "attak" in bad English,just for a laugh.

Informal..you seem tense...

Does anyone know of a decent site that did shanghai benchmarks..? more then spec etc..

Sorry .

No website has done a thorough review of Shanghai yet,and that's a sad fact unfortunately... AnandTech tried to review it but failed to deliver a thorough review(they stated BIOS issues so i guess it could be a reason).
Techreport's review is late too,should have been finished a week(or so) ago.
