im getting bad BIOS image file error for both F6 and F7A .
any explanation on this one ?
help me please guys

Use @BIOS 2.11 and flash in the windows.

For F5 bios onwards, pls use the latest @BIOS V2.11
hwbot links there they already said "(use @BIOS V2.10 (?)? if you're flashing from pre-F5 bios: click)"

i didnt see that one on hwbot .
flash in windows ?
ergh, last thing i'd do in flashing bios >.<"

UPDATE:

successfully flash bios .
seems like d vdrop quite bad .
hoping that the vDroop won't be so much worst .

anyway, what does internal PLL overvoltage feature does ?
and what is the average vCore for 4.5-4.8ghz ?

this new bios really made it more stable .
couldn't even boot on F4 last time .
this bios could boot up with everything on stock setting .
will try some linX and prime later on .

thanks again for all the guides guys ^^,

without internal PLL overvolt ur proc will be limited to 4.7-5.0 GHz only.
but enabling it will hurt S3 sleep/hibernate from waking up.
I always enable it 5.0 GHz onwards, if disabled I got random windows boot issue.
yeah read about the serious vdroop on UD3. with that price no one can complain
vCore depends on chip, my 4.8 HT @ 1.476v load on LinX, but some might get a better chip as low as 1.4v (envy)

- max vCore on air/Water single threaded benchmarks ie. Pi etc.. : 1.6V (short term only not 24/7, risky!)
- max vCore on air with 4C/8T 1.4-1.45v (may vary on speed)
- max vCore on Water with 4C/8T 1.5V (may vary on speed)
- vdimm 1.6-1.65V is fine, also 1.7-1.8V wont fry the chip on air yet
- lower your CPU PLL under 1.8v might be better as compared to the default 1.8v when OC past 5.0 GHz
- if u hv prob running higher dram speed ie. 1866 or 2133 or better timings try adjusting VCCSA between 1.0-1.1v
- VTT depends on chip, some is best doing at stock 1.05v, some need 1.2v etc to successfully boot.
- try loosening dram timings when having issues with high mem speed, specially TRCD and TREF

ok thanks a lot for the info bro .
btw, heard about BIOS reverting to original one after crashing .
mine already happened .
hand itchy trying to boot at 5.0
failed and now bios reverted to F4 .
so now what should i do ?
reflash BIOS to f7a or what ?
and also how to maintain the BIOS if crash ?

stasio advised above, flash the backup BIOS chip as well by pressing ALT-F12 during boot

i tried but nothing pop up .
i tot it was done .
after done some searching saw he said that it will prompt .
btw, now its flashed to original F4 .
so do i have to reflash to f7a ?
or is there a work around to get back d f7a i flashed b4 ?

turn fast boot off and hit alt f12 otherwise it wont flash the backup bios.

doing linX test 50 run for 4.5ghz HT .

vCore 1.4v
vDrop 1.392v
vDroop 1.332v

really crazy vDroop man !
btw, getting 50gFlops on ram stock 1333 cl9 .

normal or low ? any comment guys .

oh btw, y we're playing with ht on ?
aren't ht off better for gaming or something ?
should have gotten better gFlops with ht off . . .

4.5ghz HT on 1.4v BIOS Hyper212+ on 1x Blade Master fan .
other settings all on stock
vDrop 1.392
vDroop 1.332

Bloody hate the vDroop man !

emm..

You can use Vcore=>Normal + DVID
or
please read this thread on XS forum:

dual channel is 128-bit, 4 sticks are still 4 channel hence the bus is still 128-bit.
4GBx2 is easier to clock coz populated dram slot (2GBx4) would need more vdimm, vtt and/or loosen timing ie. CL8 to CL9 etc..
Like my GSkill RipjawsX, 2GBx4 needed above 1.7v vdimm, higher vtt for 32M benchable.
unless if loosen timing then only u can tame the voltages.

U might consider Corsair Vengeance 1600MHz 4GBx2 1600 8-8-8-24

@stasio

Its a video . Will check out later on . Now in class . Btw hows d vcore + dvid work ?

dvid only kicks in when u r under load so when the clock goes down to 1600 on idle u r drawing default voltage on vcore.

i just got myself a v6gt and throw some f12 fans on it and it turn out great only bout 9 degree higher than my water cooling and got rid of the default fan vacuum cleaner noise lol.

so the vCore will be based on the vID is it ?
and u mentioned clock goes down to 1600 ?
i've disabled all thermal inspection and energy saver features on the system .

then it wont do much i remember it will be 1.35v + offset

ok thanks for the advice owikh....now u start to poison me ...so which is equivalent to Corsair Vengence C9...i saw Corsair XMS3 C7 and C9...any other brand such as G.Skill Ripjaw, HyperX and etc.

in scenario, if i take XMS3 C7...so mean i can loosen to C9 to compensate higher vdimm and OC to 1800 or above?

u guys really make me tempted to play with higher frequency RAM because easily u can get LinkX above 54 GFlops even 80++ and i manage to get only 45Gflops..and lower PI... ok this sounda childish, currently im using Corsair Value 1333 4GBx2pc (CMV4GX3M1A1333C9) and tried to get 1600 ..but fail even booting to bios

Hey anyone ever tried on stock setting OC? *say only change multiplier leave everything else stock. using Hyper 212+ here.

How high Mhz on average we can get for 2500k? I know it chip dependent but would like the average number.

May be TS should post this setup in first post or I am missing something?
