Dual Core Opteron Thread #2

actually, the temps are pretty accurate. I've been checking the mobo temps in bios regularly, and usually they are dead on, if not differing by maybe 1-2C.

I'll definitely take your advice and try a lower memory clock. Maybe I'll use some DDR400.

By the way, I think the message is finally out, that this thread is a database of steppings. period. not necessarily stable, but just what an individual user's experience with a stepping was so that other's might gain some knowledgable information from the thread. I'm happy with my processor, only because I found this thread and have learned much from the regulars on here. This is one of my favorite threads on the forums. Good debates, good chips, good knowledge, and good peeps.

If you don't like, go back to Tom's Hardware Forums.:p:

yea, i've had some chips that would only do 2880 at 2/3 divider (PC3700 OCZ), but with a 1/2 divider could clock up to 3ghz

man. im still trying to get the volts down on my CCBBE. ive tried every memory setting under the sun and still cant do better then 2.8 @ 1.475v :slapass:

gonna do some major burning in to see if it helps

What LDT voltages are you guys using when clocking to something like 2.9Ghz on your opteron 165-170's? Is a higher LDT voltage necessary? Need to know what to use when I finally get mine in the mail.

^^^ I used default for vLDT and chipset and worked OK at 334x9 LDTx2.5. Absolute_0 says he ups both .1v but only to be sure. I tried both ways and both worked the same, so with lower volts there's less heat :D

Okay nice to know, I think I am still on default LDT voltage of 1.3 with my SLI-D, that is if thats indeed the stock voltage:) Just doing some homework in advance of me getting that opteron 165, bought it on ebay so its coming from US, luckily not bought from an overclocker, so its still sealed and unmessed with heheheh. Do you think my bios will suffice for my opteron 165, suppose I just keep my 623-3 bios, got TCCD memory.

Can anybody explain me how burn-in process works please?

@1.55V & @2952 mhz only 1 hour of SP 2004 @48 C load
@1.55V & @ 2970 mhz only 25 mins of SP 2004 @48 C load

Last night I left my computer running 2 instances of CPU Burn-in (disabled error checking) for 8 Hours @1.55V & @2970 mhz (that is still undervolting that speed but was I supposed to run only at a speed that it was 100% stable at?)

Now it can't even run SP 2004 @2970 mhz @ 1.55 V for more than 2 minutes.

Ambient temps and all settings are exactly the same. And I have cleared cmos and started from scratch.

Any explanation is appreciated. Thanks.

This asks the question of if people want some stability test measurements, then why not start a NEW thread (since this issue keeps coming up over & over again), and have people post there ONLY if they are prime stable for 4 hours (or whatever) or rosetta or ...Then whoever starts it, can put as much work as itznfb does to make a list.


This thread is useful as a guidline, not as a guarantee that your chip will hit that speed and be "stable".

Something like the Dual Core Opteron Stability thread. :toast:

CCBBE 0610DPMW
1.344 volt without ihs

you might be able to go a little higher. my CCBBE goes to 2780 at 1.32V. If you're lucky like thunderstruck, you'll be able to get a little higher than 2.8 with like 1.28V :slobber:

You mean 1.26V;)

With a little guidance from Repoman, I finally got FSB on up there (334x9). This was done at 1.62 volts on the core. Since then I've done pretty much the same speeds and tests at 1.59. Watercooled of course (see specs below). :banana:

You both mean 1.300 idle and 1.33 load :p:

Anyway the 0615 is 100% rosetta and game stable at 2970@1.45v, but it freezes almost right away at 2979. Weird chip huh? Only 27MHz behind the 0608, think I'll keep it :)

Glad to hear I could help rapier ;)

My chip has the exact same behavior as yours except mine stops being stable at 2970@1.475V. 3Ghz gets more unstable with more voltage. Maybe we can work together to find a solution. Its a strange problem to have a chip not like more vcore to add stability. Its not like its alot of volts or anything. 3Ghz @ 1.5V 9 minutes prime stable, @1.525V 6 minutes prime stable, @1.55V 2 minutes prime stable????? I have watercooling and the ihs is removed so I know heat is not the problem.

Could 0610DPMW owners post a few screens with batch num included? I'm interested to see whether or not my coming 904 will be consistent with other people. I have heard that 904's perform better, but the results are rather inconsistent and sparse in number.

Any 0610 please post, thanks! :D

S&M very hot for cpu stress:D

Yes it is pretty strange.. I will look into it a bit more, this chip has a lot of potential, it's really strange your CPU can't do 3GHz but can do 2970. I have a proven board, ram and cooling that took my 0608 up to 3.15ghz somewhat stable in cool weather, so the CPU is the only limiting factor :)

I think I can take the voltage down a little, but it's a little assuring to have an extra bump. Still testing...

Does anyone know what stepping 165 Monarch is shipping out OEM? Mine shipped out on thursday so I'm hoping it is something decent :)

Still Tweaking. Any more advice?:clap:

take out 2 sticks of ram.
Doesn't 4 sticks make it harder to overclock?
2Gb should be done with 2x 1Gb sticks

those who have the CCBBE and UCCC mem, can you post a ss of your a64 please?

im desperately trying to find some settings to improve my oc.

or even PM me with a link. thanks a lot

I read on a few occasions that with 4 sticks in most cases all you need is to raise the memory voltages a bit to compensate.

I just started on my CCBBE 0610.
I got to 2.9ghz @ 1.45v, and after 15 minutes of prime it's not failed.
I tried 3ghz, but right now I can't even get close with 1.5v.

I just downgraded from watercooling to a TTBT as I want to make my computer more portable.
I'm getting 32 idle, and 49 load, so I need to get the airflow going better in this case before I am going to do an 8 hour prime (a good measure of stablitly IMO). I miss my water :(

49c Under load is very good on air imo.

Take off the IHS. You'll shave a lot of your temps. If you're not comfortable doing that, and you really are concerned about your temps(which you should be, because these CCBBE's are sensitive to temp), then you need to go back to the WC solution or put your system by some air conditioning, lol.
