Thats why I think my problem is heat related as PRIME95 generates much more heat than Super Pi
Any Ideas anyone :)

For 2.8GHz I am using 1.475 + 102.4 that shows as 1.51Vcore in bios and 1.488Vcore in windoz CPU-ZQuote:

I have a 165 CCBWE 0551 UPMW that does 2.8 with Big Typhoon. I still have to tweak it but I feel I can make it stable. Likes juice much more than the mighty 170 0550 UPMW. I need 1.350vx113%. Still burning my BH-5 tho, now I can't get to the 166 divider with 312HTT :(Quote:

165 CCBWE 0550 UPMW
300HTT x 9, 2.7 @ Default vCore + 104% VID on SS.
Dual SP2004 stable.
Will not for the life of me boot past 300HTT, 301 hangs before Windows loading screen.
Suggestions?
just wonder how high it can go with default voltage.:confused:Quote:

Then the "problems" began. Core 1 is a killer. Ran 20min prime @ 2.8GHz stock voltage. But core 0 craps out at 2.65GHz. Now running dual prime @ 1.52V and 2.8GHz... So far so good. :toast:
BTW, IHS is still on and max temp I've seen is 43°C with watercooling. Not bad, is it?
have you tested the max. HTT of ur board?:confused:Quote:

I can believe that the cpu core 1 has reached its physical limit, so, even without IHS, it could keep crashing. You can try with extreme cooling, but you can have the cold bug problem with it.Quote:

do i need to reinstall anything? reflash my bios? or can i go from one processor to another of the same type?

its running at 2.7@1.5v now
it fails prime within seconds, but i can run superpi and i can bench it (3dmark01, 3dmark03, aquamark 3
any clue?
EDIT: also core 1 fails within a minute running at 2.7g@1.55v in bios
EDIT AGAIN: my pcie card is in the bottom slot, and my ram is in orange. could that be affecting anything
On DFI boards, RAM are supposed to be in the orange slots, so that's good. It's probably heat that won't let you OC. I know you're gonna say "NO stupid I have the Big Typhoon", but trust me on air, 1.55v isn't going to work without cold nordic air. What temps are you seeing under load at 1.4v?
my temps are low, around 45ish even with 1.55v, so its not the temps, its just my cores fail
Sorry to hear that, you sounded really psyiced out about getting the CPU. Maybe it likes lower vcore? I mean, 2.7 isn't really pushing it.
i HAVE A 165 0551 UPMW @ 300x9 with 1.375x113% (1.536v in CPU-Z). core0 won't go any higher :( I can prime @ 312x9 in core1 with a bit more voltage.Quote:

when i reach windows and open ITE or CPU-Z it shows 1.392 so I believe my Board as got an offset (not sure this is the exact word...sorry!) 0.05v
my question is: can i reach 1.6v in windows? (that would mean 1.65 or more in BIOS) would it be safe? with a Big Typhoon on my 165?
i think i got a good stepping since it primes (2 times) with the config I said before ( 165 -> 2.7 @ 1.392v) what do you say?
is there a deadly vcore or it has to do with the temperaure only?
thanks in advance! sorry for my english!
Voltage kills faster than high temps. A combination of high vcore and high temps is even more deadly.
Quoted from another board:
---------------------------------------------------------------------------
There are 4 ways that chips break:
electromigration: metal atoms in a wire move around because lots of lots of electrons hit them. Move enough metal atoms and the wire will either short with another wire, or have a hole in it and stop working.
TDDB: the insulation material that separates two key parts of a transistor breaks down creating an electrical short - which breaks the transistor. In most cases, if any one of the hundreds of millions of transistors breaks, it will break the chip.
hot-e: a key parameter of the transistor called "Vt" (threshold voltage) shifts over time - which essentially slows the transistor down. If it slows down enough, then the chip will calculate an incorrect value.
BTI: Similar to hot-e but for a different type of transistors and happens for a different reason. Usually fixed in the factory.
In all but hot-e, increasing the temperature a little makes the chip a little more likely to break (this is all statistics... there is no "do this and this will kill your chip..." it's all a matter of probability). In hot-e, lowering the temperature makes it worse.
In all of these, increasing the voltage a small amount makes them much more likely to break the chip.
As to why 10% more voltage is much worse than 10% more temperature, well let's take the example of electromigration and look at it in detail.
Wires are made up of atoms all lined up. Electrons flow through these atoms. An electron is a very small thing, and atoms are a lot bigger. So the idea of an electron moving an atom around is a lot like someone trying to move a car (atom) by shooting a BB (electron) at it. Clearly to ever hope to move a car by shooting BB's at it, you would need a lot of BB's... a storm of BB's. But if you get enough, the car will move. Millions of BB's and that car will likely start getting pushed around. The temperature of the chip could be thought of as how slippery the road is. A little bit more slipperiness isn't going to help a BB move a car. It helps a little but not a lot. On the other hand, the voltage determines how many BB's you have, and it's not like 10% more voltage is 10% more BB's (electrons), you get a lot more than 10%. And worse than that, because increasing the voltage in a chip also increases the temperature (all things being equal, like same heatsink, same air temp, etc.), increasing the voltage is a double-whammy.
The others are similar... but more complex to explain (I'm still not sure that the experts really completely understand the low-level details of both TDDB and BTI...).

2.8 GHz prime stable :D
It could probably do better, but temps. rise towards 50*C....I think its bad IHS contact as i've reseated my waterblock 4 times, and i get 35*C idle temps in a 18*C room :stick: My GPU on the other hand is at 28*C idle and 45*C load(volt-modded, #4 in the 3DM05 ORB, #1 in the 3DM03 ORB for its class)
Still, far from shabby. I'll keep the IHS on, as IMO, a 100 - 200 MHz gain isn't worth the risk. Besides, I can bench at 2.9 GHz, and run super pi 1M at 3 GHz :)
from your temp. and volt., already risky enoughQuote:

Note:
1.the same post as here:
http://www.xtremesystems.org/forums/...ad.php?t=88292
2.don't trust the temp!, thats is after stopping the dual prime, the real temp about 43-46 full load on both core
3. On stock cooling@5000 RPM
4. I live on tropical island so the damn temperature about 30-33C
5. Question:
is my max temperature just 49c?, thats what the Tcase said..

I second this..and what does the offset mean..add or subtract ??
I think the thermal offset is the temperature you must ADD (not SUBTRACT) to the current cpu temp, in order to get a more accurate reading.
ok..but how do you find this value?Quote:

I've been saying this about the thermal offset for a month.. and NO -7C doesn't mean subtract, it means add. The thermal offset is on the CPU, not the MOBO..
My 165 supposedly runs 22C idle on a big typhoon air cooler in 25C ambient. So am I really running 14C? :rolleyes: No I'm running 30C because the offset is -8C. My 148 with no offset ran 33C on the same setup BTW, so it's not the mobo.

hmm..very strange..it reads temps as 38C...speedfan 4.27 says 31-33 C...offset is -8C
so if I were to add 8C what do I add it too....speedfan's 31-33+ 8=39/41 and does not equal 38C reported by the program..very odd
Got my new 0550 UPMW opteron 165 running 2700 Mhz @ 1.32v, got my ram running (9:10, so 270 Mhz @ 2.53v). Seems to be very stable, running a long pass (90min) through S&M. I'll post a SS if it passes.

I prefer the interface of SP2004 :p:
cool... my offset is 0
It means the MB is taking the real CPU temp, and adding whatever the positive offset is. And when there is a "-" it takes the real temp and subtracts whatever the offset is.Quote:

BTW are there certain dividers you guys find that are more problematic than others..supposedly at DFI they stated some opterons do not like 9/10 and 5/6 divider...did not say if this was dual or sinlge core

I would figure the normal dividers would be ok???

*** Click to enlarge! ***
Will aim for higher later :)
thats fantastic for 1.4v:D
why does everyone say the voltage off cpu-z..knowing that it does not match there bios setting and given the overvolting of this mobo it is very misleading
the vcore above is not 1.408..it is higher as cpu-z always reports a lower value
on my setup ..1.45*1.04= 1.508 but cpuz reports 1.456, the same value when I give 1.325*113%=1.497, cpu-z again reports 1.456....
with that said..TIMKO that is awesome overclock!!!!
i think everyone pretty much understands they read under. cpu-z is just easier than remembering your bios settings. i change setting so often, sometimes I can't remember what i set the vcore to:eek:Quote:

I've noticed that in most cases for DFI NF4 mobos that the voltage you get in any windows app will be approx 0.02v lower than what you *see* in the BIOS. This is the only A64 mobo I've had since almost a year ago so I don't know what voltage readings are like with other manufacturers.Quote:

http://www.xtremesystems.org/forums/...94&postcount=8
As an example, the voltage I used for my current 2.8Ghz is 1.275 x 113% = 1.441v. Bios shows 1.43v and Windows applications will show 1.41v (or in the case of CPU-z with its 3 decimal place reading 1.408v).
As for the overclock I've achieved, it's pretty much par for the course with this particular date and stepping of 0550 and UPMW, see this thread -> http://www.xtremesystems.org/forums/...ad.php?t=86139 where mag¦c achieved the same speed at slightly less volts (1.392v) :banana:
