depend on how gud is d weaker core & whether it's on ddr2 or ddr3 platform. x720 be tends to do better on latter platform.

consider it as charity lah bro, buat baik dibalas baik mah... who knows u'll tersepak duit di tepi jalan again...

crosshair 2 is a gud board, but hot chipset + less support (less user) makin it not an ideal choice. either go D easier way or a$u$ m3/m4a, which i think not worth d moolah if ur not gonna pair 'em w/ high end chips. d dilemma is am3 chips perform better on ddr3 platform (many case show that they use less volt on ddr3 boards compared to ddr2 boards), so if ur gettin a high end am3 chip why not pair it w/ ddr3 board then instead of runnin 'em on premium ddr2 boards. i'd say it's a tough call...

what chip ur runnin on that 790gx board? if d "coreclock" is referrin to htt u can try to increase d parameter in cpu configuration under t-series page (iirc). larger numbers mean higher htt oc is allowed.

is on board gfx is in use as well?

well if d diff is big enuf, by all mean go for gx & save some $$$. but in sgp, d diff between dfi 790gx & 790fx is just a $4, so unless u want a matx board else there's no reason not gettin d fx.

250htt on 7750BE should be doable with some tweaks, d higher prime stable i managed was 267HT w/ moderate ram freq, i believe thre'll be better mileage if lower ram divider is in use. most agena can't really do htt > 300 unless it's a gem.

http://forum.lowyat.net/index.php?act=Atta...=post&id=879095

btw, nice volt w/ that kinda timin & freq...

no offense taken bro, i mentioned it becoz i encountered d scenario myself. d lower multis i'm referrin to are not low multis like 10 - 14 which require one to do high htt like 250 or 300. for eg, on 7750BE, i can't hit 3.3GHz w/ 16.5 * 200htt, d setup was bootable but very unstable regardless d temp (< 60'c)/volt (<1.6v). but w/ "lower multi (that i mean)", i was able to do prime stable @ 3.3GHz w/ 15 * 220htt. any multi > 16 was as gud as nothing to me back then when i still own d chip. w/ lite htt oc like 220 things are not that complicated at all.

i've seen some heavy oc done in xs that involve mix of "lower multi (that i mean)" & lite htt oc. so w/ my own experience backed by some examples that i read i took d risk to make suggestions to some of d guys here.

but as we all knew, oc mileage for everyone is diff, even w/ same piece of hardwares one mite not get d exact result as others.

cheers

i dun have d luxury of tryin a$u$ board bro, financially not allowed coz i'm not single & w/ limited income, i need to think of some other things while keepin myself happy (obviously gud hardwares). i'm nowhere near bro dblooi & bro clawhammer (otai since k7 era), i'm just voicin out my suggestions as an user only...

of all those that i manage to try were abit ax78, biostar 790gx a2+ & d loan unit in 790gx3. dfi was d furthest that my wallet can afford, no regret thou d board is no longer w/ me now.

meh, i'm just a lite clocker only bro, i can share nothing but some amateurish experience only.

we're on d same boat sis, but for me it doesn't matter what d oc setup is > gone were d days where higher fsb gives better performance, d thing i concern most is high clock (allowed by my crappy coolin) + low volt. a chip which can overclock well but able to undervolt always give me orgasm...

ceh, x nak... i7 wannabe...

that's bro Entropy (from vrz)'s previous setup b4 he switch to ddr3 platform w/ msi gd70.

either bios issue, onboard sensor or dts for me. bios issue can be determined by tryin other version, onboard sensor can be verified either usin d chip on other board or pop in another chip into d board in use, while for dts can use coretemp to check.



tested 01/13/2009 bios on 790gx3, no problem, even my old 790gx a2+ & 790gx 128M have zero issue w/ d temp readin. was a bit surprise few users to have face such problem.

u need atleast an agena, toliman or kuma to have d acc feature provided ya board come w/ sb750 & a bios which support that feature. if ur runnin of brisbies, windsy or older am2 chips, u won't see it in bios evan ya board come w that feature.

imo, aod is very useful for voltage tweak if u have all d option available which depend on what mobo u use. safe u lotsa times for rebootin d pc just to change d voltage. slight htt & multis (htt & cpu) adjustment is ok but not huge jump, else d system will lock up almost immediately. it's a pity that they didn't include adjustment for nb freq multi & ram divider, if these 2 are available, aod will be a perfect tweakin tool for amd chips especially agena & deneb...

that would be an added point for the board...

alamak, yg stock punyer bios xbleh pakai ke sis? same jer ngan biostar, ko x pernah pakai biostar ke bro sis?

give us some poison, some pics to show d sexiness of d board pls... nice theme w/ black & red...

bro, tu nvidia chipset mobo cikai ke top notch punyer?

amd 790gx aint cheapo chipset leh, kinda unfair if u compare a 790gx (mid range) board to non 780 board.

since when i become so influential? i'm not sayin that biostar is not gud, they're great as budget board, but pairin a highest end chip w/ a great value board doesn't look match for me. biostar 790gx has weaker pwm if compared to 790fxb, it's ok if mild oc involved, but mid to high oc will constantly stress all d components to their max, so imo it's important to have a board of better built quality, which i personally think 790fxb is. however, there are better board out there in a$u$ m3/4a 79.

gamer != overclocker, markettin gimmicks sometimes do work eh?

apesal aku kene plak?

u sure always up to date eh bro? do dfi proud, i'm outta d business ledi... may D force be w/ u...

meh... i'm really out ledi... later ppl say i poison newbies just to buy dfi only not gud loh...

salivatin but no $$$ to buy d toy how? u sponsor can lah...

yup, lite + mid oc (w/o long hours of primin done) is ok for biostar boards. me not hardcore as well (infact i never did any hardcore oc didn't i) ledi nowaday.

w/o a doubt biostar is always d 1st choice for value + performance.

actually i believe biostar can do as gud, but one really need lotsa skills + experience to get d best outta it (which obviously i don't have), that's why i went for d easier way instead.

pls save ya money & spent it elsewhere, either D or a$u$ will do d job well enuf...

so fast... hehe... biostar + kuma is just for warm up...

but do bear in mind 790fxb can't run any unlockable x3 720/710 prime stable. however, jr 790gx has no problem thou...

lotsa 0904 batch can be unlocked, so shouldn't worry much. EPMW is one of d best i've seen...

me pong same jugak... dah retire pong kene...

a notch or 2 won't hurt, but u gotta be careful when d volt reach more than comfortable level (1.45v *my personal preference only). long hours of stressing w/ high volt will seriously hurt d pwm.

one still can use am2+ chip on am2 boards, but not all (depend on whether manufacturer include d microcode for a particular model iirc). i think ya board is an am2 board, max bus speed @ 1400 (ht 2.0) say it all. am2+ is of ht 3.0, which its bus speed @ 2600MHz.

This post has been edited by ah_khoo: May 12 2009, 04:26 PM

yup, anything more than stock (for 7750) would be bonus. d only thing need to take note of is d pwm. d board has a weak pwm (2 fet per phase [3 phase in total] if i'm not mistaken, pls correct me if i'm wrong). neway, i doubt d board can clock kuma well enuf that huge voltage will be involved, so no worries there.

d temp is a 'lil high to my liking, w/ such a gud cooler at moderate clock (for a 940BE) load temp shouldn't be as high. mebe some lappin + better TIM will help. mx-2 is my fav TIM.

it's all down to personal preference, some prefer prime (like me bein kiasu) for maximum stability while some like 3dmark/games/ibt as their stability measure.

air flow plays an important role as well. if ya case temp is high then no matter how gud d cooler is also can't help much. case temp rise along w/ d usage of pc, d longer u turn it on, d hotter it will get, but it'll stop at one point anyhow. by maintainin a gud case temp does help in reducin d temps for all components.

that was exactly what i did previously when i installed my own pc for d 1st time...
