Mine too.

Im using abit EQ to monitor the chipset voltage.

How about room temperature ?

guys, need some help here... wat cud be d reason (in particular) of system freeze after primin for hours? my system is stable when prime with small fft (8-512K), but when i run blend test, freeze happened.

i admit that expert is harder to tame if compared to ultra-d, but there must be a way, just short of time to find out what is d culprit as i'm busy w job huntin lately...

ram settings, ldt voltage, chipset voltage or vdimm? i notice that expert needs more juice than ultra-d or nf4-d. still my nf4-d is d best of all so far, but it's resided in my gf rig currently...

It seems that all the voltages were at stock, increasing it might help i think. Especially the vChipset and vLDT and vCore.

expert is for "expert" only
ram setting could be the factor and it's more difficult to tweak compare with nf4 older series. btw, expert vdimm overvolt 0.01v or almost same as the value in bios unlike overvolt much in older nf4, that's why sometime it need higher vdimm.

I think what limits my x2 overclocking is the psu. I increase all the voltage also cannot go, errors at the 2 round most of the time. Time to get the fortron 700w..

yup, i just increase d ldt voltage by one notch, mebe should try increasin d chipset voltage as well. nothing wrong w d vcore i guess since it passed small fft w/o problem, headache comes when ram is involved...

yup, mebe am just an expert wanna be... am tryin to burn it w/ memtest test currently, mebe d ram need time to settle in w d new mobo. too much option available in d bios for this expert, but am kinda like it even it's torturin me now...

am aimin ocz now but pocket empty, they just come out w new series lately if i'm not mistaken.

the bios is almost same as nf4 series if I remember correctly, just the ds/dds option more advance. some tips for you, try the lowest value first, weak 1/ lvl 1 instead of auto and the yellow slot in expert mobo is "cacat"

why dont go for corsair psu?

exactly... can't even boot up even i've tried to switch d position. i'm usin lvl 14 now, so far memtest ok. odd no = weak while even = normal, d smaller d no. d weaker it is, rite gsan bro? auto wud be d strongest of normal if 'im not mistaken (wild guess only since it starts w 1 instead of 0).

corsair modular psu? hmm... modular psu is not my cup of tea leh...

as I knoe, lvl 9 and above is for 4 dimm, but I never try before. you're right, odd=weak and even=normal. my bh5 can up to ds/dds 8/4 at 250MHz @ 2-2-2-5, any frequency above it have to tweak from the lowest value. if I not remember wrongly, OPB suggest that only set ds to lvl 1 then tweak around the dds from lvl 1.

i see... shoud try ds = lvl 8 then. same here, i alwez use dds = lvl 4 for tight timin ram. i thought tight timin ram shud use normal, only tccd or high frequency modules use weak ds eg. lvl 1, 3, 5 or 7? hmm... will give it a try after i'm settled w gettin a new job, as for now, work is more important...

what psu ure using right now? chapalang one ar? aiyooo
ure rich kid what....go n buy PC&cooling power psu lar.....

If you are using the best hardware out there but dont know how to fully utilize it better use an el cheapo rig then.

2.9GHz @ 1.328v

Really envious of you proc man. Nice proc you have there....

What is the secret? Burn the CPU at high voltage first then down-volt?

Nice man! I need more wattsssssssssss..

Stress the cpu 100% for some time then u can lower the voltage.

So let's say my core is stable at 2740 Ghz @ 1.40v. Should I just stress it at that level or go higher, like 1.45v?

Another thing, I tried to downvolt my proc at stock 2.2 Ghz and it went all the way down to 1.129v!!! Immediately failed if I put it at 1.10v. Now orthosing at 2.2 Ghz @ 1.129v!!!

Is this advisable or it is even recommended???!!?? Will post this question in the hardware Q&A section.....

Run ur proc at that speed and voltage for like 1 month, and then lower the voltage to 1.375v and try again. To lower the vcore u need to do a very long burn ins..

Ok. Thx.
