hi all,


for those who wanna try BH5 with IC7Max3, just forget about it ok. (i saying this because i'm the max 3 owner , and i own 2pcs of the mobo before)
for my S478 system, i still used IC7 but just the plain , not max3 version.

max vdimm on max3board was 3.2V but anything set over 2.9V will have stability issue.
(u all can check in major site saying the problem on the max3 and yet, abit was not ganna do anything about that.)
the problem was the VTT not set to half of the vdimm u set, as stated in Jedec standard,

VTT to feed will equal to 1/2 of the Vdimm u set in BIOS.

the max3 only can support to 2.9V (with correct VTT voltage feeding)

anything more then that will have screw up the system stability.


BUT there is alternative, fot the Max3 mobo, u can do VTT mod on it, and just some soldering and track cutting......but i bet no one
will try that

for those who wanna try BH5, beware as not all PSU (esp those 24pin PSU) will not support the booster.

the booster only can be used with the 20pin (aka old type PSU) which have the white cable (not remember is -5V or -12V)

very troublesome for those who wanna get BH5

(i was once own 3 set of BH5 , Team Xtreem BH5 , OCZ BH5 and Corsair BH5)

i was running my system most stable with 2.9V at 220Mhz. i just can't feed more then 2.9V there.

***but trying DFI NF4 Ultra-D which have the max 4V vdimm option, my BH5 fly high : 2-2-2-5@250, with 3.5Vdimm feed

but now i sold all the BH5 already, as going high density liou.

anyway, to those who still OC the S478 system, happy OC and exploring.

@fylon,
i still have a pair of Patriot PDP 1GB Kit. (PC4200 @ DDR533)

this pair was my fav. before i switch to Corsair 3500LLPRO.

it serve me well thru 270Mhz with 3-4-4-8 with 2.8V . not bad right.

** but the best ram was the one i'm using now, doing 1:1 @DDR550 @2.5-3-3-7@2.8V,
which is the Corsair 3500LLPRO

anyway, if u r interested with the ram, just give me an offer thru pm.

happy OC

@fylon,

it really depends, if u would like to try tight timing or high fsb, just go ahead, as this OC was really a self/personal thing, u try, u gain something, u didn't try, u also didn't loose anything.

so do what u feel it's right, and the most important thing, njoy the moment, the moment u reach there........your ultimate goal for OC.

happy OC

Albert

try to get the ram cooler from allngap or from karom
it will help to cool down the ram.

bro, is it a corsair BH5 ram u got? or mushkin?

might interested with it as my ultra-D lying around doing nothing. my ultra-d have max 4V of vdimm so i will try it
for 2-2-2-5@250......just if i was lucky enuf.


*i just sold my PDP ram to Fylon, hope he can fully utilized it. (and also take good case of it)

@Fylon, u will love it when u saw it for the 1st time, it have the bloody Red colour theme.nice touch from PDP.

@fylon,

just try not to supply over 2.9V on the dimm. and best if u can have active cooling on it before OC.
as for your 3.2E, 3.8G was a good target. try reach there with low vcore.
u'll love the speed.
last time i was doing 3.8G with my 3.2C (but northwood 3.2 seems not OC-able to reach 4Ghz) and it's was not fully prime stable.

anyway, nice target u have there and try yr way up there.


rgds,
Albert

@fylon,

u still have more headrooms for the PDP, 235@2.5-3-3-7@2.8V still achiveable, just please make sure that your NB have a proper cooling.***(very crucial)***

as for your 3.2E, stock vcore doing 3.6G was ok. i think more then 3.6G u have to increase vcore abit. just my experience.
had u run any prime test?

nice OC anyway. try to squeeze more from 3.2E, but leave vdimm max only at 2.8V . just don't feed it over dos.

*about the cooler, i still have both cooler : the TR XP-90 and the Scythe Ninja Plus. both are good cooler actually, just the XP-90
was abit better due to the nature design of it , which benefit for the PWM and NB to cool down together while the CPU do. BUT, u should take noise into consideration, as XP-90 need have high CFM fan to shine. my chooice was Nidec 92mm @ max2800rpm, just great combination.

as for Scythe ninja plus, 120mm fan = silent. 1200/1800rpm fan serve well with it. nice and silent but abit larger size.
u need to check the clearance if u wanna try this cooler. so if u interested, the price can nego.


rgds,
Albert

3.6GHz was a good clock speed for S478 P4 system , with all voltage at stock, u should be running it quit cool

mind to show us the temp reading?

the XP-90 was on 92mm nidec fan. it's made of nickel plate cooper blocks with alu fins.

as for the ninja, it uses the 120mm fan, with cooper block and alu fin.

both cooler weight almost the same. even the ninja was huge in size, but not in weight. haha

@khai82siong,

do u still interested with the ninja? my friend no want already

rgds,
Albert

@kabu,

nice tip there.

wanna try raptor in raid-O.

used to have Maxtor 80GB Sata in raid-O. speed was ok.

now wanna try raptor see how much different but sadly no more stock.

gonna wait till next batch come in.


rgds,
Albert

really nice to see all S478 owner here still njoying what the system can brings.

to all s478 user, congrats.

@fylon, congrats for the OC attempt. way to go for 4Ghz.

correct! i can do that @260Mhz without problem.

@fylon, go slowly, u can make it there also .

*just don't over volt too much

can i know the ram that u used. is it the famous rev.2 OCZ titanium series??? nice ram......

@fylon,

the ram timing was best set to 2.5-X-X-X

both in amd or intel system it will perform the best with that timing.

i don't see any problem for u to try 260@2.5-3-3-7@2.75V

if u have any stability issue at 2.75V, pls switch to active cool before up the voltage again.


happy OC

@kahloon,

u have a very good 12V rail.

the ram timing really nice, 2.5-3-3-5@250.

a quad pump with 250fsb was ideal case for me about P4 s478 system

nice setup bro.

how about Dell entry level 22" LCD with price tag below 900.

@pengster,

your current setup will only consume more or less below 500W.

your ideal PSU will be anything rated 500W or 550W.

go for that with true power type. if u going for future proof, get the OP650 ,maybe last u for a year, instead, get the 850W true power rating PSU. peace of mind.

those pre-OC GC was a waste of time to OC.

i was once own the BFG 68GT OC version, can't even OC more then 10%. but then the GC damn good lah.
just power hungry abit. my acbel 450W can't tame it.

nice Tuniq tower. was on par with XP-120 last time.
nowadays no fight already, as more and more heat pipe cooler
getting to market.....maybe drop out abit

anyway, a nice and cool stuff.

make sure your case can fit this monster, else get a air scoop for your side panel.

@fylon, u r not going to used the booster with PDP right?

what other ram that u have?

@likito,

what mobo u plan to used?

better start with something good, else better stay default with the
system.
