Super Pi: Opteron 144 CABYE 0536 GPMW vs FX-57 CABCE 0516 WPMW

[eva2000]

Since dinos and a few folks are getting slower super pi times with opteron that other san diego cpus thought I'd start this thread with comparisons between my FX-57 and Opteron 144.

FX-57 with 510-2FIX bios
DFI NF UT SLI-DR
510W PC Powercooling SLI







Opteron 144 with 623-2BTA bios
DFI NF UT SLI-DR
650W Silverstone SLI

exact same timings as FX-57


need to loosen Trc from 7 to 9 for 8M



need to loosen Trc from 7 to 9 and Twr from 2 to 3 for 32M run



So you can see there isn't so much of difference between Opteron and san diegos as seen by some folks.... maybe they just have some settings/OS issues or hdd issues causing slower 8-32M runs ?

Update Oct 20, 2005
Swapped to 2x 512MB Patriot PC3200XBL TCCD memory, this clocked higher and tighter than my above Gskill PC4400LE (309-312mhz 2.5-4-3-6 vs 301mhz 2.5-4-3-6) on FX-57. So thought i'd tried this ram on Opteron 144. It does pretty well except Dynamic Idle Cycle counter needs disabling on Opteron 144, but FX-57 allowed me to keep it enabled. Disabled i lost some performance as seen below:

What's the max for that Opteron on air?

Nice presentation EVA, solid testing...

What bios do you recommend for Ultra-D? I am running my Win 3500, TCC5 on 704-BTa, yellow slots. I'll have a 146 here shortly. Do you think 623 would perform better? Thx....

thanks mucker, Ivan no idea on air only use water (28C ambient room temp)

this opteron's maxtcase is 59C which is 2C higher than my other opteron at 57C - see http://i4memory.com/showthread.php?t=1536

[mucker]

Eva could you take a look at my last thread, I added a question, thx!

[eva2000]

bios recommended are 510-2FIX, 623-3 official, 623-2BTA, 704-2BTA try them all and fine the best for your ram

orange slots are always best for me

[mucker]

Will do, thank you. I have used all the above except for the 623-2BTA for the Winchester and settled on 704-2bta, yellow. I have always had sucecss using the -2 bioses, even though my CBBID is a complete dog. Anyway, thanks again...sorry for straying OT...

[Absolute_0]

Thanks for testing that, the results in the Opteron thread had me wondering.

[k00lance]

cabye 144 is very nice

[eva2000]

No probs.. always a pleasure.. me loves ram and cpus

[IvanAndreevich]

Man, these 144's are San Diego killers.

[tomati]

thanks Eva2000,

really clear and interesting ,

Eva, I think both have the same max-T...Heres 0516 cabce....

[eva2000]

yeah one of my opteron 144 = 57C and other opteron 144 = 59C (better oc'er! )

[s7e9h3n]

Well, I'll throw another cpu in the mix for comparison's sake. Here's an E6 4000+ @ 2.8G on air. (I know it's a x10 mult, but that's as low as I tested it)

[eva2000]

yeah Trfc and max async on that 4000+ 32M run helps

[eva2000]

just completed my Opteron 144 run @2898mhz

1M = 28.312s
8M = 5m 12.687s
32M = 24m 59.610s

[ozzimark]

So you can see there isn't so much of difference between Opteron and san diegos as seen by some folks.... maybe they just have some settings/OS issues or hdd issues causing slower 8-32M runs ?

possible that it's only an issue with the cabne's? or are people with cabye's and cabge's having the problem too?

[eva2000]

dinos is having issues with same CABYE 0536 GPMW i have http://i4memory.com/showthread.php?t=1510 but i think it's due to his loose max preamble, TRCD, DC disabled and slower hdds

[eva2000]

Opteron 144 run @2906mhz at 1.52v

1M = 28.235S
8m = 5m 11.329s
32M = 24m 54.766s

[Super strokey]

argh now i dont know what to do, i have a decent price ona 3800 that does 2.6 ghz stable at low volts or get one of these...

[xenolith]

^ Ahh come on, you know you want to get one of these and join the fun.

Very impressive for a $160 cpu Only 1106 MHz over stock

got the x2, might grab one of these too later next month. We shall see
