try not to tighten up d timin 1st if u are to find out d max speed of ya chip. try one at a moment will make ya life easier...

it could be d ram or d chip limitation. ram test with memtest (leave it to auto for max stability), while d limitation of chip can be found usin prime ot orthos.

in general,

find max fsb:

lower cpu multi (avoid cpu hit d wall)
lower ram multi (avoid ram hit d wall)
loosen ram timin (avoid ram hit d wall)



find max cpu:

max cpu multi
max fsb
lower ram multi (avoid ram hit d wall)
loosen ram timin (avoid ram hit d wall)



find max ram MHz:

lower cpu multi (avoid cpu hit d wall)
lower fsb & use ram multi > 1:1 (to avoid fsb limitation)
loosen ram timin (avoid ram hit d wall)


correct me if i'm wrong, still new to intel...

i trust coretemp more than speedfan or other softwares. it could be that high due to improper contact of die & d ihs. mine on stock voltage idle bout 30'C, on load d temp is about 50+'C.

8*390 is quite impressive bro, hw much voltage needed for d mentioned speed?

mem divider depend on how gud ya ram is, i put mine @ 2.5, runnin my 2140 @ 2.8 ~ 2.9GHz. d thing i notice is that some divider like 2.66 or 3.33 are not favored by d board (or chip or ram).

bro, for gigabyte board, it's more like a mem multiplier than mem divider (for ya case). 2.00 is equal to 1:1, since ddr is twice d speed of ya fsb. d higher d meme multiplier is, d higher d frequency of ram. say ya fsb is 300, if u put mem multi @ 2.00, ur actually runnin it @ 600MHz, if 2.50 multi is used, ya ram will run @ 750MHz.

for gigabyte 965p ds3 board, the lowest multi is 2.00, followed by 2.5, 2.66, 3, 3.33, and 4.

3:2 is referrin to 2.5 i supposed...

i always put everything to manual / normal, inherit d habit from dfi as manual still d best way to get d best outta every component bro.

bro, i'm not a pro, when u guys were playin with k7, i was still a pc noob...

pr0di9y and u are few of d veterans that i can remember...

ram @ ~900MHz, vdimm = 2.0v
fsb and nb voltage increased by a notch bro, btw, kucing did mentioned that can leave these voltage to stock if fsb is less than 450.

nolah, not my case, i'm doin 8*36x only currently. i've did a quick check, think d fsb wall is around 395, 400 & above sometimes can boot, sometimes cant...

d guru has spoken...

yup, if d wall is hit even raisin d Vnb won't help.

for my case, uppin vmch (vnb i supposed) by a nothc is a must when there's oc done, else, i will have this cold boot issue.

if u think ya ram is limitin ya oc, last resort is runnin ya ram w lower multi, not all boards have these features thou.

u can try to use low fsb with high ram multi, see how far d ram can go, correct me if i'm wrong...

E21x0 is hopeless in oc? u gotta be kiddin me mate. don't expect a chip to be able to do 100% of oc easily, not with air cooling atleast. am contented to run my e2140 @ 2.8~2.9GHz, on stock it only runs @ 1.6GHz...

it's decent enuf for dual core but for quad it mite not brin d best outta ya chip. our board (yes, i'm usin d same board as u) has only 3 phase something (power or wat so ever ), but those high end board have 6 phase. however, am please with d board itself considerin d price it cost me.

pls correct me if i'm wrong.

something to share with u guys...

how much juice u fetch to ya ram bro? i would say 2.2v & below are safe for 24/7 usage. they advice active coolin to be used for vdimm 2.2v & above IIRC.

for d capability of ram achievin certain MHz depend on batch, however, i reckon that hynix chippies can do ~1000MHz (DDR500) @ loose timin w/o any problem...

loosen ya timin 1st to 5-5-5-15 while u tryin to find ya max speed of ya chip. yas should be of d9gmh, which can do 1000~1200MHz @ 5-5-5-15 no sweat...

try to up vmch by a notch, it's a must for my case.

try to lower ya vcore bro, u pumped ~1.46v into ya chip? dats kinda high & not suitable for 24/7 imo... i folllow coretemp temp, however there some prefer speedfan or others...

welcome to d darkside bro...

uncle's rig so powerful ah? does he need so much processin power?

bro, our board don't really like 2.66 multi, try 2.5 u'll see it fly...

btw, u ain't need to bump d voltage, i believe no matter how bad ya chip is, it's still capable to do 10% oc without d need of extra juice...

i think it's not so suitable for our case bro, since our chips (e21x0) have fsb wall @ around 400 +/-, it's better for us to push the ram more...

pls correct me if i'm wrong...

bro, i believe not all chip are capable of that.

am on f12 bios bro... i took me one day to realize that our board dun really like multi 2.66 n above. my ram is of d9dcl, d lousiest chippies from micron.

ya ram is on what chippies?
