Hi folks, i am going on a mission critical task for the next 5 days. i oc-ed the first comp in my signature to 295HTT, but it passed super PI32M and failed sp2004 orthos beta seems to have no glitches when i use it for surfing and some audio editing juz now.

in the next 5 days the comp is going to run wavelab 5.0 and doing audio recording and format conversion etc. i can't afford it to crash/reboot in the midst of recording because i can't re-record the stuff. once its gone its gone.

Temperatures:
idle:
cpu: 20C (air con), 25 (non-air con)
ram: n/a
chipset: 43C (not affected by air con)

full load:
cpu: 28C (air con), 38C (non air-con)
ram: n/a
chipset: 47C (not affected by air con)



now... should i leave this alone or clock it a bit lower?? the speed difference if i clock it lower is quite significant i.e. slower. thanks

pix attached:

must pass orthos... if not, there is no guarantee that it will do audio/video conversion without failure.

is there anything in the ram that i can tweak?? or izzit memang the cpu got lousy stepping

agreed wit u ... must pass the orthos

anyone dare to pump 1.6v inside???

hmm... i changed my divider to 7/10 and HTT to 305, vCore to 1.45+110%.

now i am getting stable orthos. by the time i finish test 1 at 3mins 30 secs, my PWM IC hits 57C and proc about 46C . i read that pwm ic can take more than 70C(stable) and 108C(rated) and proc max is 69C. can anyone verify my data??

edit: stopped orthos when pwm ic hits 59 and proc hits 49.

cud be ya ram, are they of uccc chippies? try to loosen 'em 1st, opty shud be ok doin d speed ur runnin @ stock voltage.

currently back to 295HTT@2.6Ghz@1.45v divider 9/10. ram is 2.6v@265Mhz 3-4-3-8. the temperatures are ok.

i can do orthos stable at 310@1.57v divider 7/10. but the temp of proc and pwm ic keep climing until i stopped orthos as posted in my previous post. wonder should i continue... haven't seen it come to a static temp yet.

yeap, dually is freakin hot... in my case, stock voltage will raise d pwmic temp to near 60'c, cpu temp to 55'c & chipset temp to ~50'c.

that's why i perfer to run my x2 @ lower speed at lower voltage, dun really need that much of speed.

how much is ur temp using core temp... use core temp to get more accurate temp... my 170 only doing 2.5ghz at 1.4vcore, 2.6ghz need 1.525v...zzz but in my opinion, i think 2.5ghz not much diffrence with 2.6ghz rite? so i juz pump 1.425v for my cpu to run at 2.5ghz... dun dare to risk my cpu at 1.5v + juz 100mhz increment...

@ footie
my dually is quite cool until i up the vCore pass 1.55 then i'll see the temp climing like nuts... this opty 165 at stock very very snail speed

@ lichyetan
ya i dun dare to pump more than 1.55. but now running 1.475 is ok. 2.5 to 2.6 not much diff. difference only noticable when its 200Mhz more. but if the clock can reach 2.8, the speed is marvelous unfortunately for me, 2.8 with sub 1.6 vCore will give me sudden blackouts/reboots.....

i din compare core temp and smart guardian readings until now... look at the difference

mine currently 2.5ghz on water, 44c-45c load during raining day, hot day probably bout 46c-49c depends on my room temp.. i tried 1.525v before, reach 48-50c for core 0 and 49c-52c for core 1, u on air cooling rite? must be good heatsink, xp-120? btw, my room temp is 30c to 33c, i think... cause last time at my cousin house my old opteron144 run at 35c max load, 29c idle using core temp!!! lol...

errr... i using si-120 with as5 and evercool 120mm fan. modded the 3pin to 4 pin.

do u get this difference between smart guardian and core temp also? smart guardian reports 10c lower than core temp

ya... i think 3800 is definately hotter than 165. other ppl also compared and got the same results.

ya, i also having same here, temp report frm smartguardian lower by 10c... btw, my opty170 now running 45-48c max load at 1.425v.. @2500mhz... want go for 2600mhz but dun dare to put 1.5v on it...

hmm.......... so we should trust core temp???

when i got this proc from dinster, he said since opty 144 can take 1.6 so 165 should take around 1.5. he say any temp should not be more than 60C.

anyway, found a thread here: http://www.hardforum.com/showthread.php?t=1080107

yup, core temp is more accurate imo. do u guys encounter a big diff of temp between 2 cores? my 3800+ @ load havin 5'c diff, guess d ihs not doin a gud job...

as for d voltage thingy, i dun specifically limit d amount of juice. d limit speaks for itself when u see how high d temp goes.

neway, have some progress w my ram oc here... just to share...

ya my proc shows core difference of 5c when full load. if u care, u can remove the IHS and try. but for now i dun dare... lolz if i have WC i guess i would pump 1.6 in for now if vcore 1.6, the temp keep climbing and erm.... has anyone found out how to unlock x2 or dc opty multipler??

ur ram OC shows decrease superPI timing or not??

i'm not into pi coz those ppl who have joined d dark side will laugh when they see such a big number. i'm more into real stability, dats y i always use prime instead.

removin d ihs? never come across my mind that i'll do so. it's only useful when ur on water imo, on air it doesn't worth d risk.

i guess there's noway way to unlock d multi, fx-60 is d answer mebe...

my water cooling kit which consist apogee waterblock not so well... although the temp are stable at 48c-51c, both core same, keep on fluctuate @ 1.525v, but i also dun dare to go for 1.6v... too dangerous for the opteron dual core... lol... btw, currently 24/7 using 1.425v @ 2500mhz

This post has been edited by lichyetan: Nov 22 2006, 04:49 PM

according to someone, u can pass prime but fail PI.. i not sure. and removing IHS gives u a drop of 5C whatever cooling you use.

just search google just now for unlocking method, unproductive

lichyetan, my clock also around there. wish i have a better stepping

i also wish i can get a better steppings... lol ... btw, now running 1.525v 2600mhz, could it safe for dailly use?

passed pi ady. problem with my ram, forgot to loose the ram timings...here is screenshot with 8 hours prime stable...

I'm running my 4200+ at 245x11, 2.7ghz, 1.6V. Using just an XP120. Peak temps r about 63c on the hottest days with ambient temps of 34c. Those r my daily use settings.

wah.... will it kill the proc faster?? coz if not then i also wanna use that temp ... currently dun care to go pass 50C full load. x2 or opty can take higher temps?

edit:
lichyetan, 2.6 enough for daily use lar.... for me i run at stock 1.8Ghz for daily use. then when i got tasks to do and need them to finish fast, then oni i OC it. (dfi board all settings saved in bios mah).

This post has been edited by joylay83: Nov 28 2006, 05:29 PM

Well, the temps r pretty good for daily use. Like right now, it's only 46c for surfing n stuff. It's only when I start gaming or ripping videos that it goes up to 63c. As long as it doesn't hit 65c shud b ok lor I suppose.

The temps shud be better with watercooling but I've stopped using watercooling coz lazy to maintain it. So I went n bought an aircond instead. Now even better, both PC n me will be cooled by cold air instead of just the PC enjoying the cooling. I came to that conclusion after wondering y on earth I spent a thousand bux on a watercooling kit when the aircond costs the same amount of moolah. With the aircond on, it's running 50C+ only.

ya water cooling is kinda problematic and mafan to maintain the difference between water and air cooling becomes significant when u run the proc full load at an overclocked speed. for example, now when i OC with 1.6v full load i am getting about 60+C. if water it will be around 50+ to 60.

and i also found that removing the IHS of the proc is the same. when full load OC speed it is very huge difference. in a rush now so can't post links. will provide source later. saw somewhere that removing IHS lowers 5C at idle and 22C at full load for venice... full load for opty 146 oni like 40+C.

another factor need to be considered is that izzit worth to pump 1.6v for long term. AMD recommend max 10% overvolting aka 1.35v+0.135v=1.485v. some fella from LYP last time OC a proc (not opty) to 3Ghz and his proc got smoked up despite good temp coz the chip kenot take the overvolting. soltek board. dunno wether his caps blew or not.

some improvement, but d temp is kinda worryin me...




Attached thumbnail(s)

hmm... i think the temp is ok coz mine also running around that temp at 2.6Ghz and Mr. Ianho is running up to 60+ ur vcore is still quite low and ram timings still quite tight. lotsa potential still

1.6 is still ok i think........ still within the 30% margin......... should be ok as long as u dun get above 85C or so

currently down to 2.53ghz again on 1.400 + 102% VID... lol... find out that my acbel 550w generate lotsa heat when running 1.5v++... and also weird problem happen... random shutdown... my Lanparty Expert in SLI... plug in da 8 pin plus 4 pin floppy to power the board also no diffrence.... maybe PSU not enough juice, but i wonder acbel 550w intelligent series cant hold a rig with 3 HDD + 2x7600GT??? twice ady it shutdown@2600MHZ once is playing games and another is BT for few days without turning off... still havent figure out da problem... maybe increase other voltage might help? anyone face this issue before?

all d connectors are meant to be connected. how many rails available in ya +12v? mebe d amperage not enuf...

what i did was:
1. get a cheapo 400w psu to power all the fans and optical drive, 1 ide hdd.
2. main 500w psu power mobo, proc, ram, 2 sata hdd, 1 raptor.
3. bought 80-120mm fan adapter from tnghian for Rm16. and a few 120mm evercool fans for RM17 from myPC.
4. take the psu apart and take out the 80mm fan. close it back. then put it back to the casing. use silicon to glue the adapter to the psu and attach the 120mm fan. now u can feel the heat coming out

now pumping voltages up a bit i can do 2.8Ghz and ram around 270Mhz. no prime coz temp shooting up like rocket when i pump 1.6v last time it died barely touching 2.7Ghz.

change the fan to evercool at my radiator, previously was nmb 80++ cfm fan, now pc more silent but temp rises 1-2c... , i also wish to add 1 cheap psu but no room in my casing ady... lol
nw, hmmm... quite statisfied at 2.53ghz... almost same as 2.6ghz with less voltage... juz a littile slow compare to 2.6 according to benchmark software...

haha u ca always take the PSU outside as long as the wires are long enough.........

may be u can opt the option of 5.25' bay size SLI power supplier

or take out a hdd into external casing

ya... i took my burner and 2nd psu to the top of my casing. cables go in through top blowhole. my psu and burner secured with scotch tape (2 inches thick type). rock stable n won't shake
