perhaps with better coolin 2.8Ghz is not a problem, d thing is dually is really freakin hot...  sweat.gif

yup, this is the HOT'est' X2 s939 that I ever seen before.

X2 3800+ LCBKE 0643 TPMW

TDP: 89.0Watts sweat.gif
TCaseMax: 71'c brows.gif

X2 3800+ LCBIE 0621 VPMW

TDP: 78.1Watts
TCaseMax: 67'c

X2 3800+ LDBFE 0623 WPMW shakehead.gif

TDP: 58.9Watts

wat to do with this tcase max bro? higher = better?  blink.gif

show of abit..  tongue.gif my ultra-d need more juice than my nf4-d in order to prime stable...  sad.gif

normally processors with higher TCaseMax can usually reach higher CPU speeds when overclocked since they able to run hotter.

no wonder your x2 e4 can overclock well, i noticed that the TCaseMax is 67'c thumbup.gif

2.7GHz @ 1.344v is simply superb...  thumbup.gif

can;t do that w/ mine even i have better cooling i guess.  sad.gif

but neway, i'm contented w/ 2.6GHz, even 2.4Ghz is ok 4me considerin d temp...  smile.gif
*
now try burning-in to make it run at default vcore smile.gif

btw, I noticed that one of the rig is removed, what's going on? hmm.gif

Wow gsan, your x2 is really cool eh 41c on 100%. Mine now currently doing 2.6ghz @ 1.35v (stock). With water, im getting around 51c under full load. Tcasemax 69c. I wonder what's the safe temp for this proc running 24/7 ?.
*
dont refer to the smartguardian, the temp reading is not accurate.

btw, what's the stepping of your X2 ? brows.gif

posting on behalf of my friend

the real vcore is 1.43 at load, measured using DMM...  rclxm9.gif
BTW is 1.43v is too high for AMD....too long nv play with AMD already....forgot about the voltages sweat.gif
*
anything below 1.6v still acceptable provided you have the decent cooling.

super!!!!!!!!!!!!! 3Ghz for X2 3800+..........
way to go


Added on May 24, 2007, 7:27 pmi manage to OC my proc till 2.4Ghz superpi/dual sp2004 stable with 1.4V set at Bios.(not really know about actual voltage)

what's the stepping of the X2 ?

Wow! Unbelievable!

What cooling are you using? What is the temperature for core0/core1?

I answered behalf on him, ninja + air-cond, temp. around 52/56'c less than 60'c, cant remember well. laugh.gif

Aiyaa.... maybe should get a better cooler than my noctua. My proc running at 2.69 Ghz (stock vcore) in air-con room already 52/56'c......  sweat.gif  sweat.gif

just change the fan, noctua original 120mm fan very suck, silent but no performace doh.gif

I guess that's true cause I can feel air blowing from the side of the fan that is supposed to be sucking in air!!!  doh.gif
*
yup, you're right. try turn off the air-cond and you put your hand on the another side of the heatsink, there's no fan come out from there and thus the whole heatsink very hot.

prime 2.7GHz @ 1.344v, original fan yield 62'c/66'c but changed to adda 120mm fan, the temp. lower to 57'c/62'c.

What e-jump said is correct. I managed to get only 2.6ghz stable with folding at stock vcore.

may i know that which sp2004 test you choose to prime 2.7GHz stable?

orthos custom, min FFT 8K and Max FFT 512K. Check the Run FFT in-place and time to run each FFT size 1 minutes(faster).

How about you ? The settings i choosed were rumoured to be the best way to stress the proc. The preset settings are not that good.


Added on May 25, 2007, 1:08 pmI did fail a few times of the orthos before it is doing fine for 3 rounds.

proc stable does not mean whole system is stable, you have to select "Blend" to test its stability or maybe OCCT wil do. smile.gif

Will try again, but do u think its better if we stress using gromacs core ? My ram is rock stable until 280mhz, now i barely reach that speed because i use dividers and lower the speed which is now only running 240+mhz oni.

not sure about the "gromacs" stress blush.gif

btw, the moster is getting stronger brows.gif

And your TCaseMax also higher!

Wah, core temp at 63'c.....  sweat.gif  sweat.gif

If mine nearing 60'c already  sweat.gif  sweat.gif  (but my tcasemax is only 65'c  sad.gif)

haha, really have to thank to elhh82 who bring the awesome stepping X2. what about the TDP of your LCB9E ? now thinking to get peltier to make it cooler but lake of knowledge...

My TDP is 71.9w as shown in Core Temp.

Since your 3800+ can reach so high, makes me wanna push my proc further...... but just that the temperature is holding me back...... keeping my core temp at 55'c max for now....  whistling.gif
*
but since your TDP is 71.9W, your proc produce less heat than mine.

I've tried to push my proc to 2.75 Ghz at 1.35v but failed orthos after a while (core temp max about 57-58'c).

Think I should increase the vcore some more? Any tips?

yup, just pump up the vcore, maybe 1.375v smile.gif

Better to play with watercooling, less hassle.

the setting same as stress proc, just set the time to 1min. not going to wc kit, no money on hand now laugh.gif

min=8, max=32, run FFT in place=checked, time=up to you

btw, what's the stepping of your X2 s939? smile.gif
