It's going very well so I think I will let it go until morning for burn in.
Perhaps I will get lucky like the others and work my way up to 2.8Ghz :)
does anyone know of any online retailers that are selling good steppings of the opty 170. Im building a new rig with a custom water cooling setup and i want an opty capable of pushing or breaking 3ghz. zipzoomfly and newegg have the lowest price but are the steppings good?
try a used one off the forums or flickerdown.com if you want a handpicked chip...
Yep I second that. - I ordered my 0606 VMPW from filckerdown and it looked like it really paid off! I am currently testing, running @ 2.8Ghz /1.4v. I'm am on stock air so there is no way to conclude this is the chips limits. Plus I am really not very knowlegable at BIOS tuning so... who knows this chip could actually be a 3Ghz overclocker.Quote:

Current diagnosis: CCBE1 0606 VMPW @
2.6Ghz 1.28v
2.7Ghz 1.32v
2.8Ghz 1.387v
I will be putting it under water middle of next week. Worst case it will run cooler. But if things go well... cooler and faster :toast:
Finally, my CPU will be watercooled this week, probably thursday/friday. How should I remove the IHS?
Hey, if you want another entry (doubtful) my chip does the following:
170 Opteron
CCBWE 0546XPMW
2.85GHz @ 1.59vcore under water. http://putfile.com/pic.php?pic=5/14312480999.jpg&s=f5
2.8GHz @ 1.56vcore under water (unverified)
Go for a nice 165 instead they seem to clock better in generalQuote:

Unless of course you have a motherboard that won't do 312-334HTT clock:stick:Quote:

Which is possible, of course, but you can test beforehand :)
there are a bunch of motherboards that top out around 320HTT. like mine.Quote:

Does anyone here know if this wafer is a good one, I can't find any info about this here??
My opteron is also very near, it has hit customs, so just a few more days of waiting;)
What is a good method to determine max htt and such on a system?Quote:

My current setup allows me to run @ 2.7 on very low voltages (bellow stock) but from that point on I need to dial in heaps of vcore for stability for example I was at 1.4v for 2.8Ghz and it was still giving out errors.
Mind you the temps were out there also. (aprox. 56c) Still I wonder if my instabilities are not due to something else other than core instability. (hard to tell)
i'm not really sure how to find the max HTT. for instance on my MSI, it crapped out at 323HTT. i was on 1/2 div and 1.35v on the cpu, so i knew it was a HTT limitation.Quote:

that was the worst post ever ^^
made no sense
Ah well good to know and it makes sense because I experimented and sure enough I too can peak way out there in HTT with lowered dividers. It has to be something else I guess. How about the memory controller in Opteron's is there a way to manipulate the demand on those when overclocking?Quote:

i really think it just comes down to the limitations of the memory controller, and the HTT.Quote:

my mobo topped out at 323HTT as i said. but when i bump up the LDT voltage to 1.3 and lower the multi to x2 i can hit over 340.
Well that could indicate that either its in the core (higher clocks) or, it could also prove to be in the ram. I know the Opteron memory controllers do demand more when outputting higher FSB ratings. Perhaps it all comes down the heat control. I noticed on my 0606 that as I raised the FSB the chip heat output would raise accordingly. I am not an expert but perhaps this could indicate that the memory controller is putting out more heat as a result. If this were the case it would take additional cooling to counter that factor.Quote:

It just doesn't make sense that a chip would require so little power to scale to 2.73Ghz and then demand almost an additional .15v to move another 50Mhz.
Whatever the case, I'm hoping water cooling will fix it :)
What of the other hundred or so options in memory settings. Do they have any relevance to overclocking stability?
Another question I had was, if you lower the multi and raise the FSB to test max HTT does this actually work the memory controller as it would under the typical strain of overclocking?
Hi there guys, because there is so little opterons in australia, and those that are for sale having bad steppings, i am going to order from the US. Can anyone link me to the cheapest price of 3ghz capable 165's as i am unfimiliar with US stores.
Thanks for your help.
check out www.flickerdown.com look at what steppings dave has and then compare with other results of that stepping in the database.Quote:

Some chips just fail @ that temp no matter what voltage or overclock speed. My 170 does 2.8ghz with 1.4vcore 49'c. If I prime @ say 55'c it fails no matter what voltage or speed. I had a 165 that would hit 2.8ghz with 1.42vcore on air & it primed 12 hours @ 56'c. Some chips react differently to heat, some are just plain hitting a wall like mine. Hopefully when winter comes I'll find out if I'm wrong about my wall. Just my 2 cents:rolleyes:Quote:
