Dual Core Opteron Thread #2

[niexa77]

also, i've been setting 1.4 x 1.048(1.4672) which reads as 1.42 in win...

However, just (du'h!) noticed that all my rails are reading low in SG. 12v = 11.71 (always, load, idle stock volts, over, doesnt make any difference)
3.3v = 3.07-3.08 load (lower under higher load) 3.09 idle
5v = 4.86-89 (down to .83 under load)

could this be causing most of my cpuv misreporting probs? when im "giving it" 1.51v and its reading 1.47 im prob giving closer to 1.47-1.48?

just speculating

[niexa77]

i have a few aces up my sleeve (fan adapter and 120mm Getto-style delta (using 92mm atm) and just got my liquid metal in the mail :P

quoting myself, how sad :P i've also had the last 3 post all to myself, also prob sad :P

anyway, the aces, they worked a treat... put the 120mm and the liquid on tonight,
my 2750 (250x11 @ 1.4 x 104.8%) setting went from 46-48deg load to 38-40 degload...
that said; when i pulled the HS from the ihs i noticed that the ac5 had only spread to a smallish (OZ 20 cent piece) off-centre(on the ihs) circle...

still HAPPYHAPPY!!

Well I went to sleep while it was priming at 2.8 gonna try getting it stable at 2.9, this is a CCB1E 0609FPMW.

[ineedaname]

I finally got 2.9ghz decently stable but its running at 59C should I be worried?

I finally got 2.9ghz decently stable but its running at 59C should I be worried?

What voltage are you using? Define stable, how may hours of prime? If thats with just a couple hours I would say thats too high a temp that I'd be comfortable with. I don't like 12 hour prime temps above 55'c if I'm gonna run my cpu @ thats speed daily. The CCB1E steppings run warmer than CCBBE's. Especially on air. I keep my CCB1E @ 2.8ghz 1.4vcore. Seemed to be the sweet spot cpu speed:volts:temp ratio. Anything over 2.8ghz just wasn't worth it for me volt/temp wise. Is this a testbed overclock? Most people that are reporting these amazing clocks don't have their motherboard/cpus in the case. If you don't, its definitely too high a temp, because its only gonna rise once everythings installed in the case.

Should you be worried? No not really prime/rosetta apps are about the only thing thats gonna heat up your core's like that anyway. If you just gonna be gaming/surfing then you probably won't hit those temps. I just like to leave my cpu @ the best cpu speed:volts:temp ratio for everyday use. Gloves are off durning benching

[The Nemesis]

currently priming 2970mhz @ 1.475vcore

[ineedaname]

Thx 4 the info Nemesis!
I did some more prime and 2.9 wasn't as stable as i thought
I think the problem has to do with the mobo cuz the heat pipe is like 50C.
Maybe I set something wrong.
Also the 12v ATX is only doing 11.97v

[ocZZZ]

anyone have a 165 CCBBE 0615EPMW? I've seen many results with DPMW but not the EPMW (other than the few in the initial posting). I am thinking of selling my current opty that does 2.7ghz at stock voltage but runs very hot (55c with big typhoon). I am hoping the CCBBE will run cooler - thanks for any help.

Me too !!!!

Finally installed my watercooling kit (Swiftech H2O-120 premium) and now running at 9x330 with my opty 165 CCBBE 0610DPMW ..904.. (got it from monarch a few weeks ago). CPU load temps are 50C, but my chipset is getting real hot (70C) because i think it's not making good contact with the cooler (but it still seems prime stable - only ran it for 1 hour)

Prime test @ 2970 mhz 1.47vcore complete. Should I go for more or does everyone want to see what the 170 CCBBEE can do?

[ineedaname]

MEMEMMEMEMEMEMEMEMEMEE!!!!
I wanna c!!!!!!!!

[alfaunits]

Nemesis, test the 170, we want it ;-)

[niexa77]

my G/F's 24/7 machine :P finished with it i think, can push it to 2.86 but it needed 1.58v... and it gets toasty. I'm in the meddle of winter so i'd have to wind it back come summer, which would be painful..

ram can do more, but dont know where to start: nemesis, any ideas for tighter timings on the rdx?

Nemesis: Bring it! bring it now! :P

[alfaunits]

What mobo are you on? You can use the A64 Tweaker to do tests in Window to get best timing for each setting, and set it in BIOS )the last before a crash )
Two related questions, though:
- Can anyone tell me what the best settings would be for non-T settings (the right side of A64Tweaker)?
- Why no BIOS supports Cycle time (Tras) delay < 5 when some RAMs support even 3?

DFI LP UT RDX200 CF-DR [ot]Heard theres some bioses avail on dfi-street that fix some of the cmos-clear-ram-slot probs and give us some more OC stability: any idea if this is true nem (or anyone else with one or in the know)? i couldnt find zip [/ot]

so tweak with a64tweaker then memtest(or prime?) in windows? (i've only ever done bios-level ram tweaking then memtest bootable...)

or tweak down till crash? (thought some timings would "work" in windows, but not be stable...

[alfaunits]

Correct, some would work in Windows but aren't stable. If you really want to tweak it (let's say you want to tweak Tras):
- Set to 7 - do any mem test in Windows for a short time (like Prime95 torture test)
- Set to 6 - same
- Set to 5 - etc
When it crashes, go back one value - set that in BIOS, and run memtest from CD.
For any timing, I know lower is better - but I am not sure for the other values which is better (such as 2 or 8 Beats, 16 or 256 cycle time etc) - if anyone knows for each/has a link, I'd appreciate it.

I gave up on latencies, as I need memory bandwidth rather than latencies, but the above is how I minimized latencies (did 2-5-2-3,1-7-10-1 )all lowest except 10T (I don't recall what that one is called ... @ 200 MHz).

so tweak with a64tweaker then memtest(or prime?) in windows? (i've only ever done bios-level ram tweaking then memtest bootable...)

or tweak down till crash? (thought some timings would "work" in windows, but not be stable...

[itznfb]

here are some initial results from a guy i know on OCForums.

Opty 165 CCBBE 0617FPMW

preliminary results.....

3060 Mhz (stable)
340x9 @ 1.5v vcore
150 3/4 on the ram (cannot remember exactly?)
3-3-3-9 1T @ 2.8 vdimm (2x512mb TCCD)
704-2bta bios

[MoTiG]

hi

i have the possibility of choosing a CCBBE 0610DPMW, but there are two of them and i need help:

1434904C60443

1434904C60164

which one is the best?

ty

[ineedaname]

Hey guys i have a slight problem. Well I managed to drop the overall temp in my box to 33C and CPU to 51C on load. Those seem like good temps but i'm still failing prime @ 2.9ghz 1.52V. Is adding voltage the only thing i can do? The one core seems to fail prime even when i'm only priming 1 core and the temps are at 45C. Also how much does your voltage usually jump by? Mine seems to jump by 0.016+- is this normal?

[WhoDunIt]

Perhaps one of you more experienced overclockers can help me out; I have a 165 CCBBE 0617 (thanks Dave) and it has the weirdest scaling with speed/voltage. I can get 9x313 prime stable for 12+ hours at stock vcore (1.392 in CPU-Z), but I cannot get any higher than 9x325 at 1.584 V (CPU-z). I'm inclined to blame this mobo (A8N32-SLI) since it has wildly varying voltages. To get 1.584 V under load, I have to set 1.625 in BIOS. Then in windows, it idles at 1.648 V and load is 1.584 V? Thats a 0.064 V drop. Is this normal? Note that at stock vcore, volts dont drop nearly as much. My power supply is PC P&C 510, which should not cause any problems.
Temps are all within reason, 50 C max under load at highest vcore (I have watercooling on the cpu only and a cool room, ~22 C ambient). Other setup/settings:
RAM: OCZ Gold PC3200 2x512 Memory divider 100
Video Card: PNY 7600 GS (just for testing since it doesnt use too much power)
Dual Raptor 74 GB Drives (not RAID 0, which i have yet to work out on this board)
Watercooling is Swiftech H20-220
TT Armor Case

Any suggestions on either whats going on or how to get a higher stable clock?

[itznfb]

@WhoDunIt, i can almost guarantee its either a LDT limitation, or a odmc/RAM compatability issue.

hey ty, as far as i know any of the 1434904C60XXX's are best... but i dont own a 904, so maybe search through the thread for someone who has one and ask them for thier results(if its not in thier sig :P

[Rufus7]

MOTG both are very good cause of 904 Wafercharge. The Batch is not so important. Test them and you will see. Difference between both can be only between 100-150Mhz max.

[Got Chow]

I have my Opty 165 CCB1E 0609FPMW at 2.85GHz (317x9) @ 1.475 stable - 2 instances of Prime 95 for 24 hours. Motherboard is DFI SLi-D on the 623 official BIOS. Temps are a little high. Swiftech Apex Ultra WC kit with a 7800GT inline after the CPU. Both cores loaded it is about 52*C, one core loaded, about 42*C. PWMIC temps are high too, both cores loaded, it's in the 72*C range. HOT.

I'm having a problem going much higher too. I can get it to run Prime95 for a couple hours at 3GHz (334x9), but that is 1.6x vCore and running insanely hot, probably 60*C, if not a tad more. This setup is fully enclosed in a case though and is not a bench computer... just a regular desktop and gaming machine. Hence I sacrificed some MHz for voltage and temp. I will probably try to get a couple more MHz with the 704 bios, but truthfully I'm a little sick of messing with my computer and not using the darn thing.

If I were you, (if you don't have it already) would go and get a NV Silencer 5 Rev.3. That will help a lot to lower your GPU, PWMIC and in-case temps. When I changed from a 7800GT to a X1900XTX stock cooler, PWMIC went around 10-12c down, all that with a much hotter card

Also, if the comp is for gaming, you can try and keep it at 334x9 and have an eye to the temps. A gaming/normal use comp rarely gets to the CPU usage that prime stresses, hence the CPU temps could be reasonable.

I also had to lower the mem divider, to keep vdimm for my BH-5 at around 3.1v. That also helped to PWMIC temps.

And... I would try lower vcore, 1.6v seems a lot for a CCB1E0609FPMW. 1.4v x 110/113% maybe?

Don't know too much about WC, but those temps seems really high. What ambient temps do you have? Maybe a remount of the CPU block?

Hope it helps
