Nive vcore Steve!! :toast:
Now, you're talking Steven :) Great clocks and fast run :up: I'm glad you finally figured this CPU out...Quote:

Keep pushing it... Who knows, maybe 3.8GHz in 32M is doable :toast:
Thx...atm, it doesn't look likely that a 3.8Ghz 32m is possible because I'm hitting a wall @ 14x270. And unless my attempts at unlocking the cpu by switching memory and setting weird values from bios works :p: , it won't happen. The cpu looks as if it has a cold-bug of sorts at these temps. It can't sustain a Spi run for long @ these HTT's. I've got to brainstorm and see what I can figure out.......Quote:

Yes I know.......My DOTHAN is made in year 2004....;)Quote:

I have an 770 DOTHAN that could do with the default adapter/cooler about 2850MHz.....After moding the adapter, I was able to push it at 2940MHz.......Today I did some more mods on it which I think they will be almost identical with an A64 platform......With the new mods onto the adapter now my 770 works at 3043MHz with the default heatsink as for Super-Pi and 3030MHz 3D benchable.......;)
Make sure you keep all of us posted :toast:Quote:

Dothan's don't usually have any cold issues @ -50C core temps :p:
This locked multi is kicking my ass :p: I've found the exact point where this cpu starts freaking out - 272HTT @ -73.8C Evap. Once temps fall down that low, everything locks up. This is making it VERY tough to get off any SPI runs above 3800. I did manage to run off an 8m (actually quite a few) but 1m was another story. Once the bench finished, I literally had ~5 seconds to open all the necessary windows (cpuz, smart guardian, a64 tweaker, irfanview) before I captured the screen and saved it. It took me about 15-20 tries to finally get the screen saved before my rig locked up - but I must say....it definately was worth it :woot: Here's the results of today's work :p: :

And this is the one that took quite a few tries to get saved:

I'm about to try to corrupt my bios on purpose in hopes of unlocking the multipliers on this cpu :rolleyes: If I had access to the x15 multiplier, a 1m @ 3900 would surely be possible.....
why not loosen MAL/preamble for more stability ??
The cpu is rock solid at these timings...Actually, I've been able to finish those benches with RP as low as 4. It's just that this combination returned better results than any others. Tried them all (within reason): MAL 8 and 9, RP 4, 4.5, 5.5, 6 - all ended up with slower times. The problem isn't with stability at these speeds, rather it's a problem with the cold-bug ;)Quote:

Why don't you try "multiprocessor driver", Steven?
That's possible?Quote:

Sorry, my score knocked you out. I'm sure we'll see you back up there again soon though.....:toast:
haha :DQuote:

Good! Hopefully it will help you out keeping that Opty hot enough :)Quote:

I would need at least 10s (preferably 20s) and somehow I don't see it to be possible with cheap Optys, like mine. Despite your 154 being called Opteron I don't think there's any other Opty that will match yours. I'm pretty sure that Opteron 154 has more of "FX quality" than "Opteron quality" in there... Man, and to think that you're still complaining about lack of x15 multi :D :p: You're already very lucky to have x14 :slap::lol:
Grats on a super SPi32M, once again Steven :toast:
Woah, I didn't notice the difference between you and the next guy up. Look like you'd need another 100mhz on the cpu. Now if you can pull that off, you'd DESERVE to be in the top 10 regardless what your score is :p: The whole reason I was attracted to this Opty in the first place was because it didn't looik like the typical Opteron. But it definately shares one major similarity with all the other Opties - this thing puts out a TON of heat. Nothing I've ever threw under the autocascade has pushed the unit like this cpu has (and yes, that includes an x2 @ 1.67V). I'd say the heat coming from this cpu would be at LEAST 1.5x that of an FX at similar Vcores. I'm still trying to figure out how it would be even possible to run this cpu on anything other than high end water or better.....:confused: Thanks again MichalQuote:

Just look at those screenshots below and note LOADed temps with my Opteron 146 - before and after removing IHS:
Opteron 146 @3400MHz, IHS ON, SmallFFT .:. VS .:. Opteron 146 @ 3500MHz, IHS OFF, Small FFT
I literally don't know what is up with that... QC issue or sth :shrug:
S7eph3n, try running SP2004 in the background, set at lowest priority...you can mozey on around geettin that therr programs up.
Anyway, this chip is a beast for sure....but wouldn't a divider help a tad? SNIP EDIT: nvm, that made no sense....have you tried a divider though? knock down the mem controller speed a few notches....
And B_A...HOLY TIHS! Was the IHS even making contact?
Got a pic of the thermal paste underneath the IHS?Quote:

EDIT: Anyway... I don't want to hijack this thread :) Let us know how "multiprocessor driver" works out for you as soon as you try it ;)
I'd have to say, that's a lot better contact patch than this 154 :rolleyes: 50C loaded temps wouldn't be that unusual. My FX56 used to IDLE @ 38+C, 1.42V. Temps would easily skyrocket into the 60's when loaded. The opties seem to be hotter cpu's in general. I'm also thinking that the thermal paste has something to do with the high temps. Ever notice that on almost every pic of a cpu and it's lid taken off that there is NO paste on the core and basically all of it still stuck to the IHS? ;)Quote:

I may try sp2004 since I just remembered that the multi-proc tweak may produce a little TOO much heat for comfort. That was one of the issues with my win2k3 install. For some reason, my cpu would start loading up for no apparant reason (no, the multiproc hal wasn't installed). I'd be doing nothing in windows and my temps would be @ -30C when they should have been in the -47C range. That's why I've done all these spi runs on winxp....:p:Quote:

You got a bit of tweaking to do stephen, seems a bit slow for 3.8 ;)
DO NOT do multi cpu tweak. Bad for pi times. As for temps with my 146 I saw 240c idle with multi tweaked win 2k vs 220c in untweaked xp. Try a bit more vcore.
I use RightMark CPU Clock/Power Utility in the battle against clock bug.First run it and go to advanced option it looks like this:
http://www.xtremesystems.org/forums/...1&d=1139776848
Then go to ACPI State to Show/Modify and select C1 (HALT):
http://www.xtremesystems.org/forums/...1&d=1139776848
unckeck the CPU Low Power Enable and click Apply:
http://www.xtremesystems.org/forums/...1&d=1139776848
Idle temp now never goes below -20c and stays around -15c on a Hipro5 modded Prometeia Mach I with R507 and i can increase HTT with nothing running in the background.Mine 144 over 340HTT freezes in windows at -26c and ACPI Multiprocessor never helped it..........
There's a few things that make mine and Jason's? run different:Quote:

2. He's using Win2k3. I'm stuck using winxp. There's an added stability advantage to using win2k3 and as we all know, stability = speed in spi.
3. That Spi time seems a little fast to me @ that speed. It may be possible, but I'd be curious to see his tweaker settings and voltages. Also, it would be nice to know if he was using maxmem or a ramdrive. I was using none of those......
I'm not sure that result can be duplicated. I'm curious to see if anybody else has been able to run that time @ that speed, although I doubt there are many out there in the first place......
I'll see if I can improve on the score later.....
Thanks for the suggestion. Looks like an interesting prog. Got a link? And just curious how much does it raise cpu temps?Quote:
