Dual Core Opteron Thread #2

[gromet]

I'm running a 165 CCBBE 0617 @ 3.0 stable. 333x9 FSB. I did remove the HS for temps.

I would hope any 170+ could match this or do better honestly. I just dont see how 185's are barely getting to 3.0ghz and calling it good....I would shoot for 3.2+. I would love to get a 185 and play with to go above 3.0ghz, lowering the cpu multipler and increasing the FSB to get well above 3.0ghz seems possible..but S939 is slowly dying, and plan on doing upgrade at the end of the year.

have a fan blowing over it and it hovers around 75C usually . Without a fan it goes up to about 86C. These LCB9E are just very power hungry chips . My PWM never exceeded 50C with my single core opty

Sounds like the issue I had...My core didnt have very good contact w/ the HS. Remove the HS and temps droped from 40idle to 22idle, load 65 (3 hours orthos) to an average of 37.3 (24hours of orthos)

3Ghz at 1.3V.

Probably this chip can do a lot more,the only problem is how to keep temps low.
When i get the watercooling i will give it a try with ice water.

Nice OC! What's your load temp? And what vcore did you set in BIOS?

Thanks.
Load temps?No way,i don't even try to stress it with air temp at 32-35ºC,i am on air cooling.

That was only a test i was trying to hit 3.0Ghz with the less voltage i could,for every day use i run it at 2948mhz and my load temps goes up to 65ºC so is not worth to stress it at 3.0Ghz.

VCore voltage in BIOS 1.1125v.

Stealth thats a nice oc with such a low vcore. I just recently got into OC'ing but never really would a forum with such a wide database for OPTY's

I have a opty 185 @ 3029 (13*233) on air but the vcore is too high for comfort.. which equals to too much heat. If there any other settings i can change to i can boot with lower vcore?

Hi,

That was about a week ago,now things are worst.

When air temp is over 40ºC as it is at the moment here in Greece and you are on air cooling you have three options,to turn off the PC and forget it until temps go down,to run at stock speeds(which is not much fun)or to overclock your system with the lowest voltage you can,trying to keep temps as low is possible.

Now even with the voltage at 1.3v load temps are over 65ºC so i need to lower the CPU speed.

Well,there are not special settings for that,you just have to try and see which is the lower voltage you can reach a specific overclock.

Let's say you want to reach 3.0Ghz.With the voltage you have now you can do it,then put the voltage one step down and try to boot.

If you can do 3.0Ghz lower the voltage for another step and try again,keep lowering the voltage until you will not be able to boot.

Then set the voltage to where you was able to boot and stress it(i use OCCT to test for stability http://www.ocbase.com/perestroika_en/index.php?Download )to see if is stable,if not then rise the voltage for a step and test again.

Keep doing this until you find the lower stable voltage you can run 3.0Ghz.
When you stress the system for stability monitor temps with CoreTemp
http://www.thecoolest.zerobrains.com/CoreTemp/ ,if load temp goes at 60ºC then you need to lower the CPU speed,also lower the voltage and try again.

A good overclock is the one which run stable and cool.

I hope this helps.

What mobo you have and what is your VCore now?

Holy load temps! WOW..Thats with 1.1 core volts? I was loading @ 38/32 when I was running with the HS installed @ 1.568 volts! Once I removed the HS everything dropped to well below stock setup @ 1.35volts. I would remove the HS on that sucker and let the OC'ing begin personally! Want to sell that processor

That is with 1.1125v.

I will think about removing the HS,what difference will make in temps?

No,not before i push it well over 3.2Ghz

1.1125v (?) is insane lol. Do you have CPU overvoltage enabled?

[stealth]

Yes,1.1125v in BIOS plus 0.205v that Overvoltage CPU vCore and mobo adds 1.3175v in windows.

I see your HT-LINK is at 1365mhz, did you have to enable overvoltage SB and/or NB to make this stable? Any physical mods to the board? I removed the cooling-tape on PWM-mosfets (there's a long aluminium-cooler over the PWM area, I simply took it off, removed the tape and put on som artic cooler ceramique paste instead).

Once I OC'd my 165 I was having temp issues like you are. My idles where 42/38 and under orthose they immediately went to 60 and would slowly creep up. I went with a water system instead thinking air just wasnt good enough, on h20 idle was 42/38 and load was exactly the same. I really didnt want to remove the HS, but I wanted to maintain the OC I had it was required. Was easy following the instructions here, and now on water the idle temps are 32/22....under load after 24hours of orthose the average temp for cores was 37.3

It made a huge difference imo, but I dont think I had good contact on my processor w/ the HS.

Those are some interesting results you have as well...Very nice.

And blah....my A8R32-MVP doesnt like anything above 1500 for HTT

[stealth]

Thanks gromet,

Very interesting...........i think i will follow the same steps,see how is going with the watercooling first and if temps still high then i can remove the HS.

Well,at the moment there are other priorities,so i have to be patient it will take a few months to get the watercooling.

Mine doesn't either, above 1400 will corrupt my drive if I don't watch it. Doesn't matter though, 283x4 still gives me ~1133 which is good enough. Remember not to push your HTT too much, because first of all it doesn't improve anything, and second, too high may lower performance because of errors in the HT link. Though I've also found HT speeds (too much) below 1000 to cause instability as well. RD580 likes it above 1000, just don't push it.
