2.9GHz @ 1.344v is totally outta this world, nice burn in method there bro...  thumbup.gif

how many chips u have there...  drool.gif

two only la, 1 is x2 e6 and 1 is opty 146. the x2 e4 sold already and the x2 lcbke is my friend one, help him testing it tongue.gif

just looking for a better card, something around RM200, really kinda hard to find sweat.gif

one thing i've found was, if burn in usin small fft 1st, then only do blend test, there are chances that blend test less likely to fail, if just do blend test straight away w/o d former, yes, prime can fail easily...  blink.gif

really? i did not even know about it, thanks for the tip, will try it next time. actually I experienced hard time with x2 and ram. the bh5 can prime stable up to 26x @ 2-2-2-5 1:1 sync with my 146 previously but come to x2, it limited to 250, more than that have to use divider. it might be ds/dds setting, have to spend time to play around it. and one more weird thing is, do you notice that x2 can use divider even the MAL remain set to 7ns w/o increase its value, it cant be done on single core proc.

yup, that's my target card. there are few people selling it, but still cant a trustable seller.

dually is more hard to pls bro, in 146 u deal w/ 1 core only, but dually u need to please both, which is a bit harder...  tongue.gif

play less w d ram nowadays, but for me i always leave d mal & rp thingy to auto, less headache. as for d ds/dds setting, tight timin ram will be more stable w 0% (according to my experience) which only available in d 406 bios.  smile.gif

just tried but still no luck and 3GHz @ what vcore also prime failed due high temp. 64/70'c sweat.gif

Wow. You're really pushing the proc huh!

I'm tempted and encouraged by your efforts! Thought I stop at 2.69 Ghz but since your proc can go so high, I'm going to push mine too.

Now orthosing at 2.76 Ghz at 1.40v at 53/58'c....... I think I'll aim for 2.8 Ghz first. Hope to reduce the vcore once burn in done....

why direct pump to 1.4v? i believe that 2.8GHz @ 1.4v should not be problem smile.gif

Eh? How do you lower your core temp so much? I thought you're core temp was >60'c ?????  rclxub.gif

What is the cfm of you fan again?

same fan, no sure the cfm, but 2600rpm.

WOW! You removed the IHS!!! Now that's what I call an extreme overclocker!!!  thumbup.gif

AFAIK, it is not that easy to remove the IHS. You run the risk of damaging the proc, right?

Anyway, I'm stuck at 2.74 Ghz at 1.40v. My core0 always fails....  sad.gif

BTW, how high can we go on the vcore? Any tips?

Edit : Since you're into OC, why not go WATERCOOLING???  drool.gif

no money la... custom build wc kit quite expensive, not less than RM600 i think sweat.gif

i wish i cud have d guts to remove it too, but my chip is retail one, so abit "sayang" if have it naked.  blush.gif  tongue.gif  laugh.gif

haha...why not let go your current E4 and get the E6 from elhh82? I just sold my E4 last week @ RM360 laugh.gif

have u tried the max fft 512k ? I need few people to reconfirm this because i can get to 2.8ghz easily with max fft 32k but lots of error when using max fft 512k.

will post the result tomorrow, now still priming.

Using 32k or 512k for the max fft ?

Weird results from me so i need others to help also. Thanks in advance.

of course 512k smile.gif

Curious to know how hot is awfully hot? Are you using stock HSF? 1.325v is stock Vcore for your 3800+ x2, right?
*
he is using freezer64, which he told me that is more cooler than xp120. btw, 1.35v is the default vcore for x2 3800+. smile.gif

@uzairi

with fft 512k, how long you can prime before it failed?

Eh? Sure you're not going to stress your CPU arrr? Cause for me, going above 1.40v is already stressing the CPU heavily!!!  sweat.gif

Are you orthosing to make sure it is stable at that speed? And to go so high, I don't think your stock cooler can take it. What is your core temp?

@uzairi - yup, cpu difference about 5-6'c
*
1.40 is just 0.05v more than the original vcore, it still consider acceptable. it's always recommend not to raise the vcore over 10% from original value. the stock hsf he used is not the normal one, only available on X2 4400+ and above or dual core opteron, it looks cool and better than xp90. smile.gif

Sometimes 45 minutes, sometimes the 2nd round at 320k fft.

here is mine, but i'm doubt that fft above 112k is more stress to proc, because I noticed the temp. will drop during any fft above 112k. it might be memory unstable, try prime the ram only and see how's the result. smile.gif

update: 15hours prime stable

yas one doesn't count, cheatin one...  mad.gif  tongue.gif  laugh.gif

how u guys reduce d temp of pwmic? i found that it's freakin hot, d temp is proportional to d amount of voltage pumped to d chip...  sweat.gif

60'C of pwmic temp is abit too much for me, considerin i only applied 1.325v of vcore, imagine if i put 1.4v of vcore...  sad.gif

i'm thinking the same problem too, any idea?

Yeah, i wonder where they are too.. unsure.gif

My voltage supplied to the chipset fluctuates from 1.55 to 1.6v, how about u guys ? Do you think that might cause stablility issues ?
*
not sure about your mobo. but for my DFI, the vcore and vNB(chipset) will only fluctuate when the PWMIC temperature too high.
