Dual Core Opteron Thread #2

[knopflerbruce]

That's.... sweet!

Single stage, right?

[biohead]

ok so I ended up with 3400 mhz 1.45v stable. after that, voltage scaling is bad; I'd probably need 1.6v for 3500 mhz because 1.52v doesn't cut it even for 3450 mhz. have been thinking about a vcore mod but my insulation around the socket is currently blocking the spot and soldering would obviously void warranty.. any alternatives to get the mod done?

[nYdGeo]

Good day to all! I'm stuck in dual-core AMD-ville at least until the end of the year, so I just got my first Opty (described in sig below). I have only used default voltage for now, at least until the AS5 sets in.

I quick-tested using Systool, and it reached an error at 3831MHz, so I backed off to 2.75GHz, and then ran Orthos for about 3 hours. It was time for a cooling cycle so I stopped, and shut it down at that time. Is 2.75GHz a decent speed for a 170 at 1.33v using liquid cooling?

I'll give it a week at these settings, w/cycling for the AS5, then another week of testing/gaming before trying any voltage. If there is anyone out there with some time and testing of this stepping, please let me know if I have a shot at 3.0GHz, or if maybe this is one of those steppings that doesn't respond to voltage, etc.

Thanks in advance and Good luck to all!

Oh, based on the temps that I'm getting, can you recommend a safe but likely productive max core voltage? Thanx!

lol cooling cycle what? AS5 setting in what? just up the voltage! Voltage isn't bad, CPUs love it! My guess is you'll need 1.4v for 3 ghz. Personally i'd stay below 1.6vcore. There is a point when voltage affects temperature too much which then prevents higher clocks, it's upto you to find that spot.

and sweet stepping you got there

[v0dka]

Wow, nice clocks biohead. 3400Mhz stable on an Opty is insane.

And good for 24/7 WCG Even with ambient temps of over 30°C it ran over 12 hours of WCG. Seems stable to me

[nYdGeo]

Thanks for the input bio! My OCD's require that I do the AS5 curing thing, but I cannot wait to try some voltage and see what happens. I had no idea that I could safely try up to 1.6v without phase change, or at least a TEC. Hopefully I'll max out the MHz before I get to that high a voltage...but I will try it there anyway

[nYdGeo]

Well, while I believe that I have a nice stepping here, I think that I'll have to uncap it to really see what it can do. On my system with the current cooling solution, my 4400X2 running 2.7GHz at 1.55v idled at an average if 17-18C, with an Orthos-induced average maximum temp of 27-28C. My new Opty running at 2.75GHz at 1.33v idles at 18-19C, with an Orthos-induced max of 28-29C. Both temps are only slightly higher, but the Opty is running over 2/10's of a volt lower core voltage; it should be running cooler.

When I crank the voltage up, heat rises quickly. At 1.52v, the max temps have reached 34-35C! I should never be able to get it that hot. Having removed several IHS's already, I've learned the hard way that cool-running CPU's (like my 4400X2) benefit very little from having the IHS removed, but CPU's that seem to run hotter that others like it run much cooler uncapped.

Again, this is only based on my observations, and please let me know if I'm just stating what everyone already knows, but the cooler-running CPU's that I've uncapped (before I knew better) seemed to have a much better connection between the IHS and the core; the thermal paste looked perfect. On the other side of the coin are CPU's (like my old FX-55) with what appears to be air-pockets, or other flaws/inconsistencies in the paste connecting the IHS and the core.

Anyway, since they're only $100 now I guess that I'll pop-the-top, and see what happens. Happy GHz to all!

[biohead]

keep in mind that the expert board reports the CPU temperature about 10 degrees lower than actual, so 35 is actually 45 degrees. no worries though, personally anything below 55 degrees isn't really a problem. so i don't know where that exclamation mark is coming from i think 45 max at that voltage is pretty good

[nYdGeo]

That's good to know. I had noticed that at the current settings, and at complete idle, the CPU temp normally sits at 19C in Windows. However, in the BIOS, it is being reported as 25C. While that's not 10 degrees, its still way off. I guess that I noticed it but never questioned it. Would the CPU be idling 4 degrees warmer in Windows than it is while in the BIOS due to increased activity, thereby raising the idle from 25C to 29C? Hadn't thought of that possibility.

Still though, same system, etc, shouldn't the Opty at 1.33v be running cooler than the X2 at 1.55v when running at approximately the same speed? Maybe there is something about the Opty line that I don't yet know?

As always, thanks for the input! Oh, and I want a 3.4GHz Opty. Can I please have one? Can I? Can I? Damn, what's the 1M SuperPI at 3.4GHz?

[biohead]

unoptimized 26.453s

[AgentGOD]

Optie 165 @ 2.9 GHz, needs 1.45v :-\

[freakBYnature]

It seems it won't budge over 2.8 GHz, but still going with the Apevia Chameleon 550W PSU, it's a bit low on the 12V rails since I'm running a powerhungry X1800XT on it aswell. Going for a MIST 600W soon I hope, 4x12V rails with 20amps on each, total output 44.5 Amps! Not the rotten 34 max PEAK c*rap like now!

[biohead]

update, unoptimized but tweaked memory

[Trunks]

At the end of this week I have my new opty 170
I hope it clocks well

[viking]

i just got a opty 175 CCBBE 0617 EPMW
but im rebuilding my setup and i have to test a opty 165 LCB9E 0651 RPMW
first :/

That Opty 175 is a nice chip
I hope that I got the same stepping

I got LCB9E 0651 MPMW and it does 2.8 on 1.45V, have ordered a cooltek 600W to ensure that it's not my PSU troubling me anymore... Damn Aspire/Apevia Chameleon 550W sucks when it comes to oc'ing. It's ok at normal use, but not for the extreme

[Trunks]

I got the LCB9E 0703 XPMW

Opteron 165 CCBBE 0615EPMW - naked under a Thermalright Ultra-120

2.9GHz @ stock volts, RAM on the 150 divider 241.5MHz 2.5-3-2-6



2916MHz brings the RAM to 243, which it can't handle. I think this chip can easily do 3-3.1GHz on air, I'll have to test - but it's 2.9 with the RAM at it's max speed for 24/7

[CannonFodder]

I've heard the stock Opteron cooler is quite good. Does anyone know how it compares to the Zalman CNPS9500 ? I'll have a choice of using either one but I'm lazy and don't feel like doing multiple remounts to test it.

[freakBYnature]

I know the Zalman CNPS9700 is better than the stock opteron cooler. The 9700 can be compared to the one I'm using, the ThermalTake BigTyphoon 120VX, and is somewhat better than the stock cooler. Don't misunderstand, the stock cooler is quite good, but can be considered as a good mid-end cooler. The 9500, 9700 and the TT BigTyp 120 VX is high-end cooling and will perform better.

Having said that, I don't know on personal experience with the 9500, but I have tested the stock Opteron cooler with the four heatpipes, and it totally rocks - really, think the 9500 might pull off lower temps, but I honestly don't know. The thing with the opty cooler is that it is so goddamn silent - and at the same time performs so well. The AMD fan on it is also temp regulated on it's own (not PWM I'm talking about), so if the temps rise above certain hights it will start it's "afterburner", and I measured it to spin 6250 rpm!!! That's just insane for a fking 80mm fan... or whatever it is... it's small! It blew like a hurricane! When not THAT EXTREME hot (I put a 2000W heating fan to cabinet door to test this ) it only blows at 3125 rpm and is really really silent.



To make this less confusing, I use to put air-coolers in three categories;

1. Low-end - like the stock aluminium block for AMD!

2. Mid-end - better than low-end but not totally super, can contain both alu and copper, but some of them is all copper.

3. High-end - the best of them, can contain both alu and copper but has better solutions and performance then both low-end and mid-end. All copper base (personal opinion)

Nice chip! Remember I had 2 180's with the same stepping. One of them did about the same as your chip (maybe a few mhz less), the other one was a bit worse. But both were INCREDIBLY cool chips. I tried it @ 1.65v and 3.1GHz - using my Zalman 9500 - and the temps were never more than 52-53C. Which is about the same as the Opty 175 I have, except that it runs at 3Ghz - 1.26v......

CCBBE 0615EPMW is the best s939 stepping for ppl with air cooled rigs

I recommend the 9500. It's not the BEST, but still very good. Easy to mount and looks great as well, especially if you have some blue LEDs

I never tried the stock cooler, but I just can't imagine anything "stock" can beat the Zalman.

Wow! What stepping is that and where did you get it?
