@sang_karim, before u do any damange to your system by pumping more juice to CPU and ram, let just start to do the basic of the good old P4 OC trick.

the steps,
all related voltages set to default. ram timing to default too.
set fsb:ram ratio to 5:4 so that to eliminate ram as bottleneck yr OC.
started to up the fsb from 200, 205 , 210, 215, 220....... until the system become unstable.
when the system become unstable, then it's time for u to up the Vcore. slowly up the vcore with tiny increment, eg 0.05v
and keep upping the fsb till u hit the CPU wall. now u get the max OC of just the CPU.


next,

find your ram max OC. set vdimm voltage to 2.8V, timing to 3-4-4-8 (anyway, what chipset was inside your KVR???)
make sure to set the fsb:dram ratio to 1:1 (as yr P4 don't have unlock multiplier to select am i right).
start to up the fsb and u'll then get the max OC of your ram.

next, combine your OC of ram and CPU (best is to record your OC experience to a list for ez compare)
so u no need to worried about which voltage to choose for your OC.

* as for this OC experience, make sure u have a proper cooling of your CPU,ram,northbridge chipset as this the 3 main heat component. make them cool under load.

by following steps, u won't get lost that ez........happy OC-ing.

thanks for the advice ... i think my ram can't run 1:1 divider at higher frequency ... it's only kvr with psc chipset ... rite now i'm on 3:2 divider running at 3.3GHz ... will try ur method tomorrow la coz oredi late la .. wanna watch sum football...hehe ... thanks for u guide bro ...

Well.. Here come a good guide for how to OC for beginner! Hope u learn from SIFU albert here! Jk..

guys....how to set the fsb:dram at 5:4? i will only get 3:2 when i set at auto .. when i set the dram frequency at 226MHz or 330Mhz it will run at 1:1 also but with different latency .. it's 2.5-3-3-6 ... so how aaa?

Hm.. Look for DRAM speed / DRAM frequency under ur bios option.

The sequence should be in this if im not mistaken.

FSB:RAM

200:200 = 1:1 Ratio
200:166 = 5:4 Ratio
200:133 = 3:2 Ratio

* Correct me if im wrong!

@sang_karim
5:4 you can get by setting the dram frequency to 320. i think you are running at 266 if not wrong. for 1:1 it is 400. right now can you get dual channel?? if not yet stable better find the solution for it 1st before proceed oc.

@fylon
really solute you, now you got xms somemore. envy you la...haha really doubt that you say no $ and you said want get new hdd, then realpower psu and now xms. when is your next 7900?? wakaka......

No la.. Is just the normal XMS nia.. Get it for RM160 include postage. Got that money after sell off some spare part ma.. Haha! Cos now using 4 stick ram really hard to OC.. Thats why i changed to 512mb 2x.. More better!

By then.. Still waiting for the PSU to arrived. Really poor already..Haha! 79GS still far away..

P/s: By then.. Somehow put some time on garage sales u will found some good thing in cheap price! Thats how i grab my part!

not far liao...almost reach pay day liao ma.....

so you gonna let go all your 256 ram sticks??

Haha.. Dried already now.. Donate me some eh? Jk.. Hmm.. Not really sure yet. Due i wanna try see whether i can run 1.5G ram with dual channel or not first. If can i might just let keep 2 of them and let go the rest.

Otherwise, will let go all four sticks. Why? Interested?

nop....hahahaa..... no $ and dont have the mind to upgrade any more since the 2.8C. coz for me i dont have the stuffs to fight 4ghz. better save for next rig or get other better stuffs like speakers etc. old liao....have to relax a bit. XD

Haha.. Nways, after i grab the PSU. I guess it will be the last thing that im gona invest on this rigs. Not going for 4Ghz as well.. Risky! Bomb PSU once now scare already. Just wish can get back to old time 3.6G with slightly more tighten ram timing will do already. As u had says, better save up for other better thing ma. Guess i gota send the 79GS back to the supplier!

why send back?? still can push ore on your rig la. hahaha.....you have play game the 79gs will serve you alot better than the 98xt. or if you manage to get a cheaper gc like 7600gt also not bad.

haha....lucky i didnt go for 76gt last time, i even hardly utilize my 73gt right now. most is just play some old school game. other than that just surfing and watch anime. hoho.....

Haha.. Well.. S478 really bottleneck that gc alot.. No point to pump on that card. Good gc pair with a bottlenecking procs wont produce good result. XD

Yea.. If got then chance then grab a 73/76GT will do already. By then AGP version wasnt that cheap. Galaxy 76GT cost around RM400 for new set @ AGP slot. Gota think quad time before planning to buy it.

Yea.. Working now not much time for gaming. Better save the time for sleeping! Hehe..

1.5G ram with dual channel certainly yes to me (if u stick ur ram in the right channel ) i'm running it for quite sometime liao...



if i'm not mistaken, our s478 member kahloon & choongkeat is currently running X1950 pro agp ver. too did they say no to high end agp card yet ? cuz i'm targetin this card for lost planet ....arh ....SM 3.0 what a "s*x maniac"!

must run dual channel for oc aa? if single channel cannot ka bro?

no la, i mean before you change psu, its running at dual channel, after change cant. so i believe there is something that you may have to check it out. isnt that sweeter that you can oc in dual channel??

hmm ... maybe i will try to reset the cmos first la .... last nite oredi try with 226MHz and 330MHz DRAM Frequency but can't get 3:2 or 5:4 divider ... will check it later ... btw ... the guide suggest by overclockalbert ... first try to oc the cpu first rite? what is the save vcore to if i want to fidn the highest speed of the proc untill it's reach the wall?

Hi guys i'm back. Sorry for being suddenly disappeared for 4 days. My grandma is just passed away.
Anyway back to topic,the 76GT from Galxy is cheap also i think,i saw the price from lyp about RM380 only can get the 76GS version.Have to get attention,some of the 76GT are using DDR2.

Haha.. Icic.. Ok! I will try once i got my new ram! Hm.. I know.. But somhow the procs were bottlenecking the GC ma.. Even though can play game smoothly doesnt means P4 procs can fully utilized the gc.

By then.. Ofcause is a good deal to invest on this high end gc.. But $$ also one of the factor. Dont forget..

@raymond5105

Sorry for ya bad news raymond. Hope u be fine.. Cheer up! Yea.. Know that. By then. For galaxy product i can get it easily from my supplier. Can check before purchase it. RM380 @ lyn is a cheap price liao. Me here, check with dealer without markup price also cost RM410..

@sang_karim
i would not recommend prescott vcore get more than 1.5v. but better dont get exceed 1.6v unless you go for watercooling. haha.....

FYI, dual channel can get like 5% more performance boost than normal single channel, unless you manage to push it far far away than dual channel like >200MHz. if not, i rather stay with dual channel st lower speed for cooler cpu temp.

@raymond
sorry to hear that.

the 76gt ddr2 is not performing well FYI, the slower ram limits the whole performance. but still better than 7300gt but not far. if possible get the ddr3 version. of coz the price is a bit higher.

you planning to get 1??

@fylon

as expected from kch market. normally is >rm20 different. even more if the rare item.
