Motherboard high HTT search for PII 920 4GHz overclocking!
Did he really have to destroy the the "rated fsb" for high HTT overclocking?
920 @3.8Ghz :eek:
Great find AbelJemka :up:
@Caveman787
Rated FSB has almost zero influence on performance with K10.Maybe in some extreme case of triple SLI or CF,but even then i think it wouldn't be a bottleneck.What's important is the northbridge/L3 clock speed since it can be higher than HyperTransoprt(and not vice versa).If Deneb can work stable with @2.5-2.6Ghz NB clocks and 4Ghz for core clocks,it will be one tough nugget to crack :D.
Well thanks for informing me off that informal :ROTF:
Didn't notice that till I typed it.
Also I was under the impression that high hypertranport link combined with high nb speed helped increase performance a big deal.
Why the need for 2000 ht if it's not so important then?
Because when the chip is rated at 2000Mhz for HyperTr. it means the NB is 2Ghz too ;),since HT can't be higher than NB ;).But NB clocks can be higher than HyperTransport,so here's hoping it will hit even higher with retail chips.SoF already said his chip ran 4Ghz/2.2Ghz for core/NB stable on air.
As for perf. comment,user should try to get the cores and NB(L3) as high as possible.If it means lowering HyperTransport a bit,it's not a biggie,you can still use high HTT for NB clock calculation(ie. 250HTT x10 for NB/L3),while dropping the HyperTransport multi down(HTT x multie=HyperTransport) to much lower value that will allow for higher core/NB clocks ;). It sounds complicated but it's not :D.
friend of mine (musicismylife - I oc'ed on G|C with him the phenom 1m record) just posted some information about 300 HTT (benchstable) on Foxconn Destroyer!!! http://www.planet3dnow.de/cgi-bin/ne...?id=1229367623 I say this will be fun :D
Yeah i just wanted to post that link :D.Thanks ;),great info!
Most interesting quote is the Northbridge clocks he achieved (2.7Ghz!!!):
Quote:
300 MHz reference clock for a Phenom are a very good result, which so far (if at all) only very rarely been achieved. Interessant ist in diesem Zusammenhang auch der erzielte Northbridgetakt von 2,7 GHz. It is interesting in this context also reached the North Bridge clock of 2.7 GHz. Den Screenshot haben wir dabei um die Informationen "erleichtert", die noch bis zum 08.01.2009 unter NDA stehen. The screenshot we have to ensure that information is "relieved" that until 08.01.2009 are under NDA. Das erzielte Ergebnis wollten wir euch jedoch nicht vorenthalten. The result we wanted but you are not deprived.
Hell ya :up:
O_O I was going to get one of those but got sb750 instead... TRI SLI and one 280 GTX as phyics card sounds like a benching queen lol can't wait to see that ones vantage scoreQuote:

The 9850 I put under cold did 275 htt with a 10x multi on everything, but the cpu clocked better but wouldn't do nearly that much htt on air.
Look what THG brought in We Overclock Phenom II to 4.9GHz plus result (SuperPi) :cool:

Cod... I hate SuperPi as a benchmark in the Intel vs Amd wars! :shakes:
I remember all the P4 guys bragging over SPi results against my 3800 X2 back in the day, even though that was one of the few benches they could actually win....
That being said, it's nice to see the PhII break the 1M run at under 18 seconds (and to see some real numbers)! :D
If you'll notice there are a few problems with that SS:
1) Actual clock is only 4.02 Ghz
2) Voltage is Rediculously high for what we've seen from 4Ghz PhII's
3) Memory is set at 800 NOT 1066
4) IMC/NB is running @ 1800Mhz
I'm sure all the Intel fanboys will see this SPi score as a weakness of the PhII, while I see it as very positive. In the right hands, on AIR, I could see this score being sub 16s... We'll see where real world stuff goes from there! ;)
Intel has advantage in SuperPi regarding architectural differencies.Quote:

sapienti sat :D
+1 and also add ANANDTECH TO THE LIST PLEASE, they all suck INTEL'S BALLS :shakes: :down:Quote:

you gotta love the crap these sites pull. We can clearly see that the 17 sec. run was at 4.0 but trust me, there will be others that will choose not to see.
They kept the HT link somewhat high, maybe that was why they saw cold boot issues. Guess they haven't been reading at XS...
I suspect someone thinks the world revolves around them.Quote:
