Pening man...

What is Cold Boot & Warm Boot?

doh.gif...
Cold Boot - when you switch on your system from off state

Warm Boot - when you restart/reset your system it'll reboot, that is Warm Boot

Hard Reset - force reset eithe during booting, desktop mode, or gaming mode...

I need your opinion. Not exactly opinion actually..... I wanna know the truth  biggrin.gif

RAM DIVIDER QUESTION

166/200 of 270FSB means RAM Speed = 220Mhz
(CPU will be 270 x 9 = 2.43Ghz)

or

133/200 of 320FSB means RAM Speed = ~212Mhz
(CPU will be 320 x 9 = 2.88Ghz)


WHICH IS BETTER?


*add-on*
I understand that the RAM speed should always try to sync with FSB 1:1 but what if I lowered the RAM divider, does it make my Overclocking worse?
*
if i were you, i'd go for 320x9 with DDR266 biggrin.gif, CPU is everything.

i own an FX-53 on K8N Diamond Plus with GSKILL XTREME RAMS and Nvidia High End Rams
but u know what
i never believe in OC'ing pc's
hahahaha
loved stock speeds

doh.gif...duh, a good CPU fell into wrong hand, that kind of CPU is designated to be overclocked, i can hear the overclocking scream from your FX-53 tongue.gif...
well, kidding...IMO, overclock it, you never know how well your CPU/RAM can go unless you overclock it...once you hit the optimum, you'll feel the difference...take mine for example...i used to run @2.88GHz, DDR640...but during my PSU being borrowed to my brother, i have to run at stock which is very painfull especialy in online Battlefield 2...

btw, nVIDIA High End RAMS? i never knew nVIDIA got RAM also...hmm.gif

Are you sure its okay that the RAMs are running much slower than the FSB of CPU? I mean, performance wise it won't be affected?

*edit*
I found an article somewhere:
So means having RAM speed way slower than FSB will affect the performance is it? How bad will it be?
*
hmm.gif...as matter of fact, yes, it'll impact performance...say you have Team eXtreme DDR600 couple with A64 3000+ 1.8GHz... you installed both, but do note, your RAM won't be at DDR600 since it's defaulted to DDR400 (200), but you can overclock it to 300 with 1:1 without problem...
another story, you have same CPU, A64 3000+ 1.8GHz coupled with Kingston ValueRAM DDR400, i tell you what, it is likely impossible to hit 300 with 1:1, so memory divider will do the job. about performance affected, as long as your RAM speed faster than stock DDR400 (even set at DDR333), you won't be feel any much difference...

2.6GHz is pretty low, go for 2.8GHz instead icon_idea.gif, it's either your vCORE or vDIMM, try one by one. btw, what's your vCORE on 2.61GHz?

someone reply me pls. tongue.gif

@sniper, you said something about the PCI bus. what's up with that? tongue.gif

owh that...
normally, when overclocking in windows (not sure in BIOS though - but my PCI locked), increasing FSB, might as well increasing PCI bus, not too sure why's that, but it happens, so, by using ClockGen, uncheck "Ignore GSB/PCI", and you should be able overclock without worrying about PCI bus anymore...

if i'm not mistaken, that your problem, you can't go beyond 239MHz right, and from what my bro XP, just like i said previous post, just set it to 250 or watever you can get, (sure it won't boot), just hard reboot, hold "Insert" key while pressing power on button, this will bring you into boot-safe option, but still your BIOS is at 250 now, just hit F1 "Continue Anyway" and you should be able to run Windows...

hmm, if i lower HTT multiplier to 4X, then i must do the clock from 200 to 500 right? in order to get 2GHz.

default for my proc is 200 and 9x=1.8Ghz

i can only do it to 220 and 9x which makes up to 2Ghz
last night i tried to lower it to 8x and increase the clock to 250 to get same result of 2Ghz but the system hang at boots up. so i need to reset the CMOS.
*
i use HTT x1 tongue.gif, even at stock, HTT Multiplier set at 1x doh.gif, no harm done anyway...

i dun understand....
u use 1x? then how much is ur processor speed? how much is ur clock?

i mean i lower the HTT, then why i cant get 2Ghz and better?
*
from the pix i uploaded, i use HTT 2x instead of 1x, IMO, there's no slight improvement nor instability issue if use 1x or 4x, it's just make sure, you're not exceeding 2000MHz barrier...reason - not too sure... smile.gif

gosh how did u manage that?
u use special fan or stock fan?
u got adjust ram timmings?
umm.BTW did u use window vista? if u do, how much is ur score?

i used to have 2x512MB Team Extreme DDR600, and i use 1:1, the RAM can go all the way DDR666 without BSOD while booting up, but failed on every stress test doh.gif, however, i primed >8hrs with DDR640 with 1:1 @3-4-4-8 @2.87vDIMM, that's for RAM, and for CPU, yeah...my CPU capable to do 3.0GHz @stock vCORE, successfully boot to windows, but failed on every stress too though...primed stable at 2.9GHz also at stock vCORE, i did increase the vCORE see what happen, same...it won't help doh.gif, for cooling solution, i use ThermalTake Big Typhoon (idle @26°C while; load @38°C)
i'm not that pro in finding good timings, so i only set it to loose timing for more headroom or tight timing tongue.gif.

the mobo capable to do 440FSB (that's the highest FSB it can go)...of course, when finding mobo highest FSB la...so, short word...

CPU @2.9GHz; 1.376vCORE; 323x9 (primed stable)
Mobo @323MHz FSB
RAM @DDR640; 3-4-4-8; 2.87vDIMM (Team Extreme Hermes DDR600 PC4800)

Overclocking with 2x1GB Aeneon PC3200 DDR400
i've got myself this RAM module, after doing some "research" bout this RAM and i found this RAM is good i must say...FYI, i'm running on DDR533 (stable) @3-4-4-8; 2.87vDIMM, the post @other thread, i posted that i managed to get DDR550, but failed sad.gif. anyway...now running in 9:11 divider)

oic, u get it right.
yeah stupid me, i tot HTT = processor multiplier
my processor multiplier is 9x, and i dun have to drop it any lower right?

so right now, it is 220 X 9x = 2Ghz
i cant get it any higher etc. 225 X 9x becos the system boot will hang.

so i need to adjust the HTT higher or lower? BTW i got up the vcore 1 notch already.
*
okeh...if you want to test how far your CPU can go, it's easy, lower your CPU multiplier say 4x and try increase your CPU FSB (200MHz by default right)...

i still can't. doh.gif just tried just now. i've checked the "Ignore GSB/PCI" check box and then proceeded to reboot my pc.

changed it to 250mhz, can't even past memory test.. doh.gif

left it there for almost 2 hours and no progress..

how? sad.gif
*
at this point, i really no idea, because, normally, when overclocking, i used to test one by one, it's CPU, Motherboard and RAM, first thing i'm going to do is, finding max CPU clock, by using lowest memory divider (DDR200), i can pump all the way to max possible without worrying bout my RAM hit the stock clock (DDR400), after that, finding max RAM clock - this use either 1:1 or CPU multiplier set to lower than stock. try squeeze the RAM from tightest timing to loosest timing - this RAM tweak actually pretty take a while smile.gif, in theory, the loossest timing, provide more headroom in overclocking smile.gif, after that, max CPU FSB can go, this is interesting, as all CPU and RAM goes to lowest as possible. at this point, i use DDR200 with CPU multiplier 4x, from there, increase the CPU FSB until hit to max, IIANM, i've got 440x5 thumbup.gif...
so that's my overclocking experience, and normally without having problem to load it to windows...perhaps your RAM already it's ceiling? unsure.gif

the funny thing is.. this mobo that i'm using.. doesn't actually allow me to chane the RAM divider. blink.gif werid huh? my friend's MSI can actually do it but mine just can't. it's Auto i guess. sad.gif

but it can't be.. D-43 chips run max at 235mhz? shocking.gif rolleyes.gif sad.gif

doh.gif, yeah...this forum is good right thumbup.gif thumbup.gif thumbup.gif
regarding memory divider, did you update BIOS? aiyoh, D-43 runs at 235MHz is a waste...tongue.gif

any solutions around this? hmm.gif

have you tried the RAM module into DFI's mobo? (or other mobo), if can go higher than 239MHz, then it's mobo la...also, get other RAM and fix into your MSI mobo, and if they can go like D-43 or not smile.gif

i'm sure that D-43's can run faster than this. no way that this is the ceiling for them. and that's the main reason why i bought these RAM's. doh.gif and now, tak jalan. doh.gif

before you do, did you read fundementals of overclocking? did you read this thread before? smile.gif...anyway, when you jack up your CPU FSB to certain speed, and reboot - hang/can't reboot, it's due to reach to its limit...it might be not your processor, but it's your RAM...try use memory divider, and find the max your CPU can go...

not all A64 3000+ can go 2.8GHz, it depends on revision/batch, skills, cooling, luck...

it's not about temperature, yours 35°C is consider ok already...1st thing in overclocking, try with small increment, say 5MHz~10MHz at a time, reboot...make sure successfully loaded up to windows, and run SuperPI 32M or at least SuperPI 8M for quick stability test before finalizing job. you stated that, you system won't boot after hit 2.19GHz, i'm suggesting, reset your BIOS and overclock just like you did, only this time, use memory divider...this is what i did when overclock my processor (same like yours).

first thing is, i'm finding how far my processor can go, in order to get this, use lowest memory divider (DDR200), stock CPU multiplier...and then increase small increment 5MHz~10MHz like i told you...
