word, i'll get to it soon. there's a huge difference between max 32m and windows screen for me though.. like 250mhz :confused:

Okay managed 4 standard memtest86+ test 1 - 8 loops at AUTO vcore at 9x315HTT 2.5-4-3-7 1T = 2835mhz

9X316HTT resulted in errors immediately in Test 0,1,2 in memtest at AUTO vcore

Gonna see how far 1.425v bios VCORE takes me :)

But you can tell it's no CABNE like cpu (they probably do nearer 3ghz at AUTO Vcore ?? ) :(

I read through the first posts and I think even the CABNE's need ~ 1.45 vcore for 3ghz stability.

Now, if only I could get my hands on one...

cpu voltage set to 1.4v (reads to be 1.37v.. dunno how accurate that is), 2x512mb utt-bh at 1.5-2-2 with 3.2v and 133mhz divider:

max memtest boot: 2944mhz
max memtest stable for 1 pass: 2862mhz

i'll get to work on the max 32m and windows screen at 1.4v in a bit :D

Some do, some don't.

yeah, mine is definitly one of the lesser ones unfortunately. it loves voltage though :D

in summary:
max memtest boot: 2944mhz
max memtest stable for 1 pass: 2862mhz

max 8m = 2724.6mhz
max screen = 2901.7mhz

i didn't have the patience for 32m, so here's the max 8m shot:
http://www.xtremesystems.org/forums/...id=38720&stc=1
subtract 9mhz for max 32m ;)

here's max screen:
http://www.xtremesystems.org/forums/...id=38721&stc=1
i validated it too, but unfortunately i hit f7 before cpu-z updated, so the validation is only 2894mhz :slapass:

mine does 32M superpi at 3200mhz rock stable.... with stock vcore

so doesn't hitting F5 only give you a BMP image in CPUID folder rather than validation link file :confused:

yup, i hit f7 then f5, it updated between the two, thus why i have a valid as 2894mhz and a screen at 2901mhz ;)

nisco, remind me.. what's the cooling on that? :D

so does F7 give you the cvb file or whatever it's called

thanks just the info i wanted... :)

with my Opteron 144 0536 GPMW

so far memtest looks like this all 1:1 mem/cpu

AUTO Vcore = 2826mhz
1.425v = 2835mhz
1.45v = 2880mhz - 6 full loops
1.475v = 2906mhz 6 loops so far (this is 9x323mhz 2.5-4-3-7 which is the known limit of the ram on FX-57 so interesting to see how much higher it can go cpu and mem wise from here)

1.475v = 2926mhz running memtest so far at 9x325mhz 2.5-4-4-8 so far okay

1.50v = 2944mhz 9x327mhz 2.5-4-4-8 at 2.9v vdimm = test #6 errors - cpu related... so guess this is the point where more vcore is needed heh - but will try 1.50v but up vdimm to 2.95v first to see if it's mem before raising vcore

1.50v = 2944mhz 9x327mhz 2.5-4-4-8 but with 2.95v vdimm passed test #6 no errors, so was vdimm not vcore - so far 2 full loops error free :)

1.50V = 2961mhz 9x329mhz 2.5-4-4-8 at 2.95v so far memtesting okay passed 1st full loop, but 2nd loop at test #8 memtest error, so next stop 1.525v vcore to see if it's vcore of mem/vdimm :)

1.525v = 2961mhz 9x329mhz 2.5-4-4-8 at 2.95v passed 1 standard loop and a half

1.525v = 2980mhz 9x331mhz 2.5-4-4-8 at 2.95v booted into memtest and running up to test #5/6 errors now so more vdimm or vcore ?

1.525v = 2980mhz 9x331mhz 2.5-4-4-8 at 2.98v vdimm same test #5/6 errors, so guess time to run 180 mem divider :)

1.525v = 2980mhz with 9x331mhz with 180 divider mem @298mhz 2.5-4-4-8 at 2.95v standard loop 1st pass error free running up to test #5 in 2nd loop fine so far - 3ghz looks possible you'd think :D

What with this MaxTcase thing?
Higher temperature rated chips are best?

Yup mine is 67C also.

Just something which I have mentioned be4 something I think is relevant because alot of the talk here is abt wht vCore a particular chip needs to get a certain mhz.

Its no good saying

'woot, im using 1.45v for 3Ghz stable'

if in reallity your vCore is 1.52v. Why I say this? Well my Ultra-D overvolts between 0.04-0.07v depending on the setting chosen in bios. Another member who posted in this thread (soz cant remember name) also said their DFI overvolts by abt 0.07v, now these are quite large differences from bios reading and mulitmeter reading points.

If their is going to be any chance of correlating data to find if MaxTCase has any real meaning then 'real' vCore needs to be taken into account!!

Wow, nice work eva2000 and sierra_bound, non-CABNE 3ghz goodness is coming along nicely for you guys.

thanks memtest up to 3024mhz so far http://i4memory.com/showthread.php?t=1536 still some way to go by time get into windows LOL

Well guys, I'm done tweaking my opteron 146. I can get it to run at 2.7ghz on 1.488v. I'm cooling it with a Cooler Master Hyper 6+, runs at 38-42c idle, 52-57c full load. A little warmer than I'd like. This is the highest I can get it to run Prime95 24 hours stable. I'm running my OCZ 3200 Platinum Rev 2 on dividers, so it shouldn't be affecting things. Mobo is DFI n4 ultra-d w/ 623 bios. Should I be able to do better? I have the apparently famous CABNE stepping. Love this processor, but honestly hoping for just a little more. I can get it to run Super Pi at up to 2.9 and I can post into Windows at up to 3.1. 2.7 is where 24hr stability ends though.

hey! that's not stock voltage :p: :p: :p:
i guess i'll try something just as in-depth. i'm not exactly sure where this is leading though ;)

eva2000

no it ain't a competition just want to compare what other opteron users get between memtest vs windows stable at each vcore setting :)

right now i'm at 3078mhz at 1.65v memtest :)

This opteron seems realy fine... What about the same in dual-core version and higher level like the 152-154... will those make better of the FX57?
(I will upgrade sooon... so... when i see the result of the 146..wow)
