*** Official Opteron 170 Ocing Thread ***

Why are you using 2 different versions of prime?

One optimised for dual core the other not?

You are still using 100 % cpu whether you are 4 instances or 2.

have you ran dual instances at 2.6ghz? did it pass?

Lol this is killer hard, been trying for 2-3 days to get a positive result @2.6GHz but no luck so far :rolleyes:

In my 3 attempts to get a 24hour *Quad* prime pass @ 2.6GHz the stress prime running on core 1 would just stop after about 13 hours (program not responding!) or the system would completely *freeze* after 17 hours.

I should have started using this test while the system was at stock, but I dived right in there at 2.6GHz and after a few failed attempts I thought maybe it was not possible for a system to withstand this sort of pressure so I decided to reset the Opteron 170 (CCBWE 0550) to stock speeds and yup it passed no problems, now I have to fiddle to work my way up, still hoping for 2.6GHz

The stress primes are running small FFTs (as can be seen) and the prime95's are running Large FFTs (the max heat/power one).

This is in a *closed* air-cooling system in a nice warm room (i.e normal living conditions) and I have been using the system throughout testing for TV viewing, surfing etc.

This information is meant for the power-users as it has been made very clear that a lot of forums members here are benchmarkers who have no issue with an unstable system! :)

Woot! It's stable @ 2Ghz! :D
EDIT: I just saw that you actually OC'ed it 10MHz... :p

Good job it's not a car or motorbike your playing with, it would be worn out before you found out how fast it could go :D

Wind it up to 2.6 then come down 10MHz at a time till it's stable or if your going to increase the MHz by only one at a time by the time you get to 2.6GHz it would be cheaper to buy a FX60 by the amount of electricity you'll have used, slight exageration but you know what I mean. :D

lol :D

as if in any real scenario you would stress the cpu this much anyway?

if you are 24hrs dual prime stable then thats enough.

get on with enjoying the speed rather than procastinating over how much stress your pc can handle at stock! :D

I mean even the most stable of systems at stock can crash.Its the nature of pc hardware.

Quad priming stresses your PC for stability no more than dual priming. You CPU has 2 cores, load them up to 100% each core (which dual priming does) and that is as much as a 'stress' test you need to make. It is impossible to 'stress' the cpu more than 100% all you will be doing is causing the PC to lock up as much as a single core chip would running dual prime as it is trying to run more programs that require 100% than the chip can handle.

What next Oct prime? :o

That is a very good temp, 40 degrees is very nice :p

My voltage is 1.19volts, and I see 45 degrees on a naked core...so you are much better off than me..

I did this a few days ago:

Hi there, when you want to excruciate your cpu by SP2004, you should choose "Large, in-place FFTs - stress RAM", even the name sounds it is wrong, but you will know it is right from the higher temperature and worse stability.

I today took stock of one of these

Code is: CCBWE 0546XPMW

What are these clocking like?

The following list is as good as my 170 ccbwe 0546 xpmw gets:
2.50ghz @ 1.4v
2.60ghz @ 1.45v
2.65ghz @ 1.5v
2.70ghz @ 1.55v
2.70ghz @ 1.6v
i can't get any higher than 2.7ghz as my core temp hits 50ºc+ and Prime95 fails within minutes. My max cpu case temp is 49ºc.
The above clocks are super stable with : superPi32m, OCCT, 3dmark03,05,06 and 10+ hours prime95.
My only other option is to try a different bios but i believe it is the chip temperature that is limiting my clock.
Mabye not a 2.8 @ stk volts monster but still a fanastic chip :)

seems they need quite a bit of vcore to get stable at 2.7ghz
 
Thanks ive just replaced a single core opty 144 with this 170.

Do i need to change or install any new drivers now i have a dual core cpu?

I have DFI SLi-D and im using beta bios 3

Also i have an artic freezer pro.

Will these be sufficient or is it time to change the cooler :o

Well, Prime95 is the one to use if you want to excruciate it the most.
SP2004 is a bit too old and aren't written for A64, but the newer version of Prime95 is...
Maybe I should do a dual Prime95 and dual SP2004 as Big.W suggests?
 
Just been testing my opty @ 2.4GHz using 1.35volts and the temperature gets into the 70's stressing it with prime95.

Any suggestion or could it be my Artic cooling freezer pro is not up to the job?

You probably need a remount/re-application of paste or the Freezer isn't up to the job but I think it is more likely the former.
