right the cpu arrived today, interesting to say the least.

never heard of this stepping or code but here it is:

OSA170DAA6CD
LCB9E 0704TPMW

anyone heard of this code before? on the second line i presume the 0704 indicates it was made in the 7th week of 2004? didn't know they made dual cores in 2004? wonder how i got such an old one?
will test it out later today.

4th week of 2007, glad to see they are making 939 chips

How's it clock?

ok cpu is in now, it booted up into windows fine at stock speeds and windows found the extra core and did that acpi thing and asked me to reboot. rebooted but then windows froze when loading up.
tried a couple of times and still got boot freezes when going into windows.
then went into safe mode and installed the amd dual core driver, NOT the optimizer. now its booted into windows and gonna run some tests before i start to overclock.

but overclocking will deffo start today.

Cyber-Mav · 26 Mar 2007 at 17:20

crikey, even though its running at 2ghz the windows response seems to be damn quick. opening things up and generally using windows seems to be quite nippy. feels smoother than my single core at 2.9ghz :eek:

Cyber-Mav · 26 Mar 2007 at 17:32

right took a stab in the dark and set it to 2.8ghz at stock volts. running snm core 2 konked out after 2 mins. this is at stock volts.
this asrock board will not allow much vcore increase, 0.05 max over stock allowed so all i can feed the cpu will be 1.40v.
will increase vcore and test again now. gonna try 2.8ghz at 1.375v

Cyber-Mav · 26 Mar 2007 at 18:20

right currently still in the testing phase, 2.8ghz @1.375v and snm has just passed the 30 minute mark.

the temp on the cores is slightly different, one core is at 50c the other core is at 47c.
seeing as its a native dual core cpu i doubt it has anything to do with heatspreadder contact. so not sure which core to believe but i guess i will listen to the hotter one.
the big typhoon has now got its work cut out for it. hehehe

it deffo failed 2.9ghz with 1.40v so i rekon i could come mid way and get around 2850 out of it at 1.40v possibly.

what would you guys class this cpu as? is it a stud? or is it a dud?

I must say your ambitious! I would have run it at stock for a day or two at least and just get a feel for, look at the temps etc. I went for 2.6GHz as my first jump from stock and that needed 1.425vCore, never managed to get it much higher, although my cooling wasn't optimal.

2.6GHz was the same as the FX-60 which this time last year was about £750 smackers, anything more is just gravy. If you can cool the chip (and PWM) well you should see 2.8GHz, good luck!

Very impressive so far I have to say!

As for your CPU, it does indeed appear to be fresh off the AMD line with the 2007 week 4 stepping. LCB9E's seem to be doing anywhere between 2.6 and 2.8GHz. A couple on other forums with similar steppings.

I made the move from 3700+ @ 2.9 to Opteron 165 @ ~2.8. Cost me next to nothing overall by finding someone willing to buy my 3700+ for £70. On the whole I'm very pleased, running with a vcore of ~1.37V. Multitasking is very smooth and I've started folding again since it's not slowing down other things with dual core

What I'm really impressed with is your CPU temperatures under load. With Orthos Small FFT's my cores soar to around 65*c with a Scythe Ninja. Bad IHS contact perhaps. Maybe my case just has poor airflow.

On the whole, congrats. Your system should have plenty of life in it now.

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 · 27 Mar 2007 at 21:41

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?

stigggeh · 27 Mar 2007 at 22:01

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

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.

Big.Wayne · 28 Mar 2007 at 00:40

Cyber-Mav, there is no doubt in my mind you are a nutter! I can't believe how quickly you have attacked your new processor! :eek:

S&M is ok but I believe dual-prime/Orthos is what you want to be using to test your overclocks. The one thing unique to S&M is its PSU test. The only time S&M has failed for me is when my PSU was on its way out.

Cyber-Mav · 28 Mar 2007 at 00:57

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??

Big.Wayne · 28 Mar 2007 at 01:01

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?? :confused:

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 :confused:

Cyber-Mav · 28 Mar 2007 at 01:21

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.
:confused:

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??

Mr Paul · 28 Mar 2007 at 08:39

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.

I've had that too!

My rig is 5hrs Orthos stable - the pic is 2hrs i know - have a pic of the 5hr one but not here. Never seem to have the time to run it longer and i'm not about to leave it on over night!
