Running at 1806 and being fast, 2 totally seperate things..........;)

This is try four (going on right now), I crash loop 8 to loop 10. 2.33 to 2.4v, makes no difference, but I think CPUNB is too high (this CPU doesnt like to go over 2800). Core speed doesn't make a difference on if it crashes or not.
Timings are 6-6-6-18-11 1T 110
Points taken, from both threads.
Nomatter what I do superpi will fail at loop 8. Tried lower core speed, lower cpunb speed, even backed ram down to 1750 ish cl6. It's always loop 8 nomatter what combination I try...
M4A78T_E and M4A79_T clocked ram easy, usually thats a sign that the board is much less effecient.
Even the CH4E is a very very loose board, it can't hold a candle to CH3F when the cpu in question is deneb.
To let the CH4E fly you must use thuban and have ram clocked to the moon.
This paints the story very well. The deneb on CH3F has a slight NB disadvantage.
2 totally different paths to acchieve the same goals.
Deneb

Thuban

1680 failed loop 6 :d
2.02v was enough for 1600MHz 6-6-6-18 with my 965, however I don't want to do it again now as a birdy has told me that Thuban doesn't like that kind of voltage :p:
got to turn extreme overvolt on for 2.8v
EOV on 2.8v

Yes, I haven't tested it with high volts myself, but I noted that posibility, due to the Thuban-like behaviour (except the DDR-2000 capability, at least mine chips).
Wonder how is the efficiency, compared to old Deneb.
Same effec, all it changed was scaling characteristics.
I would not expect effeciency to change or clock walls unless they had a microcode update, it's probably a good thing they didn't.
On average NB clocks are 200-300 higher, on average cpu clocks are 200-300 higher.
Mine was an old C2, a very nice clocker (4GHz 1m on stock voltage) and handled as much voltage as I could throw at the RAM (I think I stopped at around 2.45v, it was still scaling past 2.4v but only slightly, is that GTR or GTS?). I never manager 1800MHz 32m stable though, nice RAM :up:
Now, I've never been very good at 32M pi. I popped my hypers in my UD5P today to give it a shot... Holy hell. Chew*, you literally are the master. The chip I've got is pretty useless for this competition on air though. Cpu-nb tops at around 3000 on air, but gimmeh some DIce and up to 3600 she goes. ;) On these hypers, 1800+ cas 6-6-6-16-18-1T is easysauce. Just couldn't get anywhere on the cpu-nb. :shrug: Pretty bad efficiency since I was in diagnostic mode on my 24/7 OS, but my best was still 30s+ too slow. :-/
I'm no master chance, I'm just a regular guy that puts alot of time in to figure out how to get the most performance out of a platform.
Doing the homework is the hard and tedious part and many times means pushing ultimate limits just to find out if something is indeed better or worse.
Once the homework is done it's just a matter of applying it.
I believe chew has realized I'm not a guy of patience but I also never get to work :p:
I realize valids are nothing and stability is everything, but nonetheless these sticks have a lot in them:
DDR3-1900 6-6-6-15 on 890FX (Actual is 1886, ths board has HTT fluctuation)

Voltages werent anything crazy, I'd almost feel comfortable at these volts over long term.
I would like to believe I'm at troubles with the IMC as far as 32M, hopefully chew can elaborate. Maybe it's just this copy of windows, some bug, I dunno. I couldn't get 32M to pass at 1660 last night.
Like I said in orginal post, suicide is easy, many guys have gotten ram very high, stable and fast however is a totally diff ballgame, I can boot and run a few loops at 1900+, I can get to about loop 23 at same speed as hypers also, Once you go for a "tuned run" you need to be ultra stable however.
Also the method your using to get there, aka 1/4 isn't very efec, much easier to get high clocks that way. 3/10 is a :banana::banana::banana::banana::banana: and hell on ram.
Ok, I think I'm gonna give up...
I regret the decision to skip the dry ice this time. If I had bought some, now I'd had CPU-NB @ 3.6GHz.
