opteron 146 > opteron 175?

[Cyber-Mav]

looks like 2.85ghz is a no go with 1.40v, errored out after 30mins.

left it at 2.8ghz now with 1.40v and thats passed so far. got the heating on now in the house so it a bit warmer. cpu at load is now 53c and 50c.
guess as long as its under 60c its all good.
shocking how much hotter its running then the single core. can;t blame it though i guess, its doing almost twice as much work as the single core.

 

[Cyber-Mav]

this is odd, im getting very high temps with this opteron. its running at 53c on one core and 70c on the other core.
using core temp to monitor the temps that is.

why such a large difference?

hmm could it be bad ihs contact?

 

[Cyber-Mav]

may i ask why you use SnM and not Sp2004 (orthos)

i used orthos before on the single core opteron but snm gets the temps higher and also detected an error at 2.91ghz on my opteron 146, where as orthos passed the cpu at 2.92ghz and that was running for 9 hours and 34 mins of orthos.
snm detected error after running for 13 mins.



gonna take the ihs off now and see how it goes

 

[Cyber-Mav]

i have had the opposite with snm, ran for ages, yet failed prime quickly strange i guess.

careful, the little transistory things are closer to the edge on dual core's.

ahh thats interesting, guess i will run both snm then orthos to check for stability. hehehe running both one after the other is a good thing, just takes time but im to too bothered with that since i have access to another pc to use to surf net etc.


right i have removed the IHS now on the opteron 170 massive difference.

before IHS removal i got load temps of:

core 0 = 57c
core 1 = 70c

now ihs is removed im getting load tems of:

core 0 = 54c
core 1 = 45c

dunno why there is still a difference between the 2 cores in terms of temperatures but overall its a massive drop, especially on core 1

took ihs off and had a look at it, looks like only the edges of the core had contact with the ihs, center of the core looked like there was no contact.

will run stability testing now and see how things go.

 

[Cyber-Mav]

right something fishy going on now with this system.

this also addresses the snm vs orthos thing too.

my pc seems to be unstable, windows freezes up when running snm or orthos.
now orthos freezes up in around 6 minutes and snm freezes up in just over 3 minutes.

snm also seems to be getting higher temps than orthos, which is probably why its more effective for me.

now that aside there is a very odd thing about this.

i boot up into safe mode and both snm and orthos run fine and there is no freezing up.

all i run in normal windows boot is coretemp and snm or orthos.
coretemp does not work in safe mode so thats not being run, just orthos or snm is being used.

whats the cause of this?
sounds like fishy drivers or something since windows will also fail to boot up sometimes in normal mode but boots up fine every time into safe mode without a problem.

im sure this looks like a simple fix, hope it does not mean i have to reformat or anything. what could be causing dual core issues in windows normal boot but no problems at all in safe mode?

dodgey this. hehehe

felt like uninstalling my vista off the test pc i have an installing in on my main pc now but heard that there is slow game performance in vista with the games i like to play which are:
test drive unlimited
stalker
GRAW
toca 2
just cause

but others say that since i have 4 gigery of ram that my general windows performance will be better than xp in vista??

Back off your overclock and maybe consider installing windows fresh since you have something weird going on i.e you couldn't even boot windows after it had installed the dual-core?

Thought that was weird when u said you had to install the AMD driver in safe-mode to get into windows??

Might help if u slow down a bit also, was your system even stable running the 170 at stock?

yea its running at stock now but its still not stable in windows normal mode.
but perfectly fine in safe mode. very strange this. safe mode the system is running fine

 

[Cyber-Mav]

very odd, orthos gone nearly 1 hour in safe mode and no errors. run in normal windows mode and konked out again in 5 mins 50 seconds.

this has got to be the stupidest thing i have ever seen a system do.

backed up my boot drive now incase i have to do a wipe on it, well not much of a back up all i have on the boot drive is my emails which i backup on a regular basis to the slave drive. need to find a way to backup my profile in test drive unlimited. just earned 65 grand and don;t want to loose that, almost there to getting the dodge viper


anyone know whats up with the system??

 

[Cyber-Mav]

Are you running Core temp from non safe mode when the crashes occur? If so there is your problem. Core temp has issues, they manefest either as system lockups or random shutdowns.

ahhhh, come to think of it thats the only time iv had the freezes in normal mode, when i was using coretemp for the first time yesterday in combination with snm or orthos. i left orthos on overnight its been running fine in safe mode and no freezes or crashes whatsoever. will run it again now in normal mode but this time ill use speedfan to measure the temps insted of coretemp and see if the freezing stops.

coretemp does not work in safe mode it just saus it can;t load io driver or something.

will test now in normal mode.

your right, coretemp is the problem. ran orthos in normal mode with speedfan and ran fine for 40 mins.
the closed down speed fan and ran coretemp while orthos was still running, 5 mins later system froze.

coretemp is a load of crap. gonna send email to lash amd in a few mins.



a question about speedfan temps:

got 4 temps showing in speedfan but not sure what they are all for here they are listed:

Temp1
Temp2
Temp3
Core

right in idle mode
Temp1 is 26c im going to assume this is case temp since its the same when cpu is put on load.
Temp2 is 28c idle but goes up to 50c when cpu is on load.
Temp3 is 26c idle but goes up to 47c when at max load.
Core is 22c idle but goes up to 45c when at load.
now im sure the sensor labled "Core" was hitting 65-70c when at load before i took the heat spreadder of the cpu so its made a big difference to me for removing the ihs.

anyone know what the other temp sensors are for? the ones labeled temp2,3 and core? i assume core is one of the cores but not sure that the other 2 sensors are reading.

For alternatves to CoreTemp, try A64Info-Beta or Central Brain Identifier. Both are just as accurate as CT, and have the added advantage of not locking your pc up when running Orthos

cheers for those alternatives.
but why does coretemp cause lockups?

 

[Cyber-Mav]

Of course I'm right

The reason I believe is that as it gets the temp values from registers on the CPU, IF you have another temp monitoring programme open aswell, I mean anything that monitors temps, core temp will confuse the carp out of the CPU and it will either think ahhh I'm overheating and shut down or just plain lock up!

I just use CBID now as it has no issues that I can see.

Oh S&M monitors temps also, so if your running core temp with that it will crash

excellent there, thanks for that info.
happy now with this cpu, running dandy at 2850mhz with 1.40v today i noticed that my winrar zipping speed increased considerably.

 

[Cyber-Mav]

I'm still at 2.7GHz at 1.33v, no point in going any higher as I'm already GPU limited (X1800XT)

yes i see but more cpu power is good for stuff like winrar and video encoding etc. im very happy with this dual core opteron, and now that the heat spreadder is taken off its running load cooler and is very nice.

 

[Cyber-Mav]

How come he's been suspended?

members market rule violation, done price drop in 23 hours when i should have done it after 24 hours.

 

[Cyber-Mav]

Mr Paul, how well is your opteron 170 clocking?

 

[Cyber-Mav]

what heatsink are you currently using?

im using a big typhoon and was getting high temps, took off the ihs and temps dropped by around 15c.
when i took off the ihs i could see that there was contact around the edges of the die but the middle was relativley clean so that means bad contact.

if you decide on removing the ihs then get a heatsink that uses the mounting holes on the board so you can vary the depth of the mount.

thermaltake ultra 120 extreme is the best air cooler around at the moment and would be worth grabbing.

XP90C

ahh, going for a new high end air cooler will make a big difference over that easily.
