Maybe ur power not enuff


Just my 2 cent

1.2kw max,rated 600watt pure...

when my cpu full load,it shown 1.26v,when no load,1.28 v

perhaps u should start using a hight quality PSU like Enermax 500W or better for a high pc like yours..

how much u bought that 600w power logic PSU?

PROBLEM SOLVE IT MY MOBO TURN OUT...RMA THE MOBO PROBLEM SOLVE IT RAWK..

I recently put together a new PC and am interested in overclocking it safely.

-Original CPU/Socket : Intel C2D E6600 w/ stock HSF
-FSB : 1066 MHz
-Multiplier: 9X
-Clock Speed : 2.4 (Default)
-Voltage (CPU/RAM/Chipset/AGP) : Default Auto Detected
-Chipset : NF680i
-Ram Type/Speed/Timings : 2GB of Corsair CM2X1024-8500C5D running at 800MHz, 5-5-5-18 w/ Airflow cooler unit
-Motherboard: ABit IN9 32X Max
-GPU: Leadtek Winfast 8800 GTX (Default clock speed)
-Casing: Lian Li PC-A10

Due the the design of the casing, I must stick with the CPU's stock HSF, at most I can only change it to one that has a simillar footprint. I would like to overclock to the following parameters:

Increase clock speed to 3GHz or higher
Current idle CPU temp is 35-40 degrees C, I would like to keep any increase to 5 degrees or less. Even if it means I can't reach 3GHz.
Get the RAM to 5-5-5-15 and 1066MHz (which is its advertised specs), if that's not possible, at least 1000MHz

Without any advice, I'm hesitant to adjust the voltage settings for fear of causing damage. Yet, I read that's the key to optimal overclocking.

I would be most grateful for any advice on how to proceed.

ermm i noob at overclocking so i hv a question
i recently try overclocking my core2duo E6400
from 2.13 to 2.4ghz

but the problem when i check wif cpu-z

my multiplier seems to keep changing from x8 to x6 back n forth

why is tat?

I think u need to disable Intel Speedstep feature...

how to disable speedstep?

sry me noob

find something called C1E / EIST and Disable it. and u can go through the article/ guide in the c2d thread to understand more http://forum.lowyat.net/topic/399602

Go to the bios setup of your motherboard, then find these two things: C1E / EIST then disable it.

Then overclock your processor like gila gila.

i'm using abit ab9 board i dont know where issit lolx
cant seem to find it

nvm i found it thx for the help

got a problem here...i use to OC my frens pc..the spec are as below

c2d e6300
gigabyte 965p-s3
512 X 2 DDR667
CM extreme 430w psu

the pc can't seem to OC anymore..keep returning to default setting when i restart it...b4 this i can OC till 2.86Ghz wif no problem...whats wrong guys...help me..oops help my fren

wanna ask, do any facing this kinda problem...?
the ds3 rev 3.3 cant boot into the POST screen, it just run 2-3 sec of blank screen then restart continously.

how to solve it?

Evogenix

same with my case and eventually i brought it RMA

Try to take out ur battery as long as possible then put in again to try lo

RMA again?
the m/b just RMA-ed 1day ago

i think they gv me your board jk-ing

Evogenix

for me, it usually happened if the board do not accept my oc. it will just cycle on-and-off infinetely. just take the battery out for a minute, and then put it back on. hope this help you. this will reset your bios

so far i have no problem when oc with f9 bios of ds3 rev 3.3,i hit my Conroe E66 with 3.825GHz....using Big typhoon vx and idle at 28c........believe it?load at 57c,will not go more than 60c

nice result.. what the vcore? passed stress test?

flash your bios back to F9?better?




btw,anyone face the problem when install the vista on sata harddisk?the sata hardisk isnt run as Ide mode

what u meant by isnt run as IDE mode? how did u know that?

my pc is quite old already dated back in year 2004.
neeed help abit here

Pentium 4 Northwood 2.4C HT @ 2.63Ghz VCore 1.55
MSI 865PE Neo2 S
2X Kingston Value RAM 512 DDR 333 2.5.3.3.7
MSI GeForce 5600 128MB
RAM chipset really dunno coz written on chip 'Value Ram' only.

From stock VCore, the most i can do is up FSB from 200 till 210.after tht,i must raise my VCore only can hit 218 in my BIOS setting.i'm using stock cooling.idle temperature minimum 33C,full load temperature is 52C(when i play C&C3).

My Vdimm still untouched at 2.5V and AGP at 1.5V.
when i up FSB,my RAM frequency will also increase paralel wif my CPU FSB.

now i'm stuck at 2.63Ghz at FSB 218 set in my BIOS,even if i raise my VCore to 1.565 and make my FSB 219,my pc cant boot into BIOS at all.

guys help me out here,is tht the scenario tht is my CPU has already reached its limits?
if not, wat else can i do abt it?i'm not sure abt the max VCore i can go for a Northwood proc.even Vdimm also

nope,i never use f10,later problem banyak banyak.
How come u say u run vista in sata and the sata become ide?

if enable the AHCI mode,then at the Onboard Sata/Ide Ctrl mode then choose AHCI,then harddisk will run as sata mode,then the NCQ function of harddisk will enable if your haddisk support it.otherwise if you choose Ide mode,then it will run as ide only

Bro, hows ur mobo ? The new one aft RMA is same Rev. ?

oh.. i never think of that. just install the windows like that. after installed windows still can tweak the setting?


hehe ya got it back from RMA. ya the one is same wif my RMA board. they just repaired it and sent it back to me.

Repaired? Not replace with a new one? Last time i get new board from RMA.
Did u ask them to replace a new one for u ?

mine was rev 1.0 when i bought last december...
after send back for RMA...i got a new board as replacement... rev 3.3 and also comes with BIOS F10...

so far so good...

Wao so nice.. Rev 3.3
Yup.. should be replace with a new mobo. Im worry about tht, becoz im gonna RMA my mobo soon.

don't know. the service counter worker just tell me they reflashed the bios only.
nvm lah~ as long as i can use it now

guys... what is the highest FSB can achieve for DS3? and what is the FSB voltage i should put? +0.1V?

and anyone using Corsair XMS2 ram paired with Gigabyte DS3? what is the vdimm? and the clockspeed achieve for XMS2? my RAM vdimm is currently +0.2V. The max i can go is +0.4, cause once i set +0.5, my system died and i have to reset the bios settings...

i'm trying to reduce my CPU multiplier so I can push the FSB higher... just to see if any performance difference... (lower CPU freq, higher FSB/RAM freq)...

i have actually asked this before but this time, wanna know a 'safe' value to put for my BIOS setting...so if anyone has a 'safe' voltage/FSB speed number as a start for me...then appreciate it... thanks!

Added on April 16, 2007, 3:49 pmwah...idle at 28c? your room got turn on air cond is it?

cause if without air cond, very hard to get 28c leh... that is like nearly ambient temperature already..... your temp inside casing should be higher than ambient....
and in return, Tjunction should be even higher...

yo guys, which bios version do you think is the best? im currently running F8..

when starting my windows...halfway...with the running bar... it just hang...

can anyoone roughly let me know if it's the FSB too high? or it hangs because of my CPU? or RAM?

thanks!

Not sure but for me, all bios seem give about the same OCability. I see some ppl can achive higher speed @ LOW voltage in F8, but thats not the case for me...


yes there are several possibilities. maybe u need to add more voltage at vdimm/MCH.

try adding some..

how's ur OC result? give us some details.

hmm... currently i'm setting my FSB at 430Mhz... ram timing is 1:1 so it's running at 860Mhz right? and my cpu is at stock voltage 1.35V running at 3.01Ghz (multiplier 7)...

fsb: +0.1V
mch: +0.1V
ddr2: +0.2V

ram timing is 5-5-5-15....

yesterday when running prime... i leave it running over night...but then today wake up...i check...my windows like no display...the screen is black...but the system is like still running... no matter how i shake the mouse or press the key at keyboard.. the monitor still dark...like the display won't come back....haha...i dunno what's wrong...so now i'm running prime again...

will update if it's stable....if stable...i'll tkae blackthyra suggestion to increase the mch and fsb...then trying to go for 450Mhz next...

Added on April 19, 2007, 8:12 amactually wha'ts the difference between vFSB and vmch?
i thought MCH is controlling the FSB as well right?

if u gonna put past 420fsb, 430 is your case, u should apply at least +0.2 at the fsb/mch. +0.1 only stable at 400fsb i suppose. For memory, its already pass past the 800mhz mark. I see u are using XMS2, any idea what memory chips under the hood? if its Micron/Hynix, u can do 2.1v (+0.3) or else, put 2.2v (+0.4) to maximize stability - this is VERY important.

MCH is the bus located between the CPU and NB. Thats why it needs separate voltage channel to work on..

wow...not really sure how to check the xms2...but i'm not planning to open up my casing yet... when i get my upgrade additional xms2 ram...i'm gonna take a look at it...

now moving downwards and starting from 400Mhz FSB first...
processor is 3.2Ghz... after 20 minutes...my PC reset... so now i up the vcore from 1.3875V to 1.4V...and then i also increase my ddr2 ram vdimm from 0.2V to 0.3V...

vmch and vfsb is still at 0.1V
hehe...

Added on April 19, 2007, 8:55 pmoh yeah...i notice hor...at my CPUZ... my vcore setting is 1.4V...then at CPUZ is showing 1.344V...that i understand la cause got vdroop...

but once i run prime on all 4 cores...my voltage at CPUZ becomes around 1.280V.... is this normal?

from 1.4v drop to 1.280 is normal la.. from wh

ur rams is XMS2 DDR2 667 (from ur sig) maybe ur ram cant handle 800MHz (ram multi 2.0) thats why u got reset. If u change to DDR800 rams sure will improve ur OC room

so here, maybe ur ram is limiting ur OC... test highest stable ram speed 1st. i think ur cpu no prob liao..

ok...i have a friend using xm2 667Mhz as well...but he's not using 1:1 ratio...maybe higher ratio... i think he did manage to get 1Ghz speed... but then again...it's possible he's lucky to get a good chip right?

that only possible if ur using Micron's D9GKX/GMH or Hynix chips..

none other than those can achieve such speed. U should be informed enough about this.

there are lots of discussion threads about these kind of chips around. Do a seach.

okay this is my first time oc-ing and i really need some advise. i dont dare to go any further than 3.0GHz though coz i need some advise first. thanks



p/s: actually i were still blurry about my ram. do i need to adjust the timing a lil bit? its 2x512mb XMS2 5400 CL4.

that would be enough for u, i'd say.

what cpu cooling r u using? at 3ghz, that pretty cool temperature u got there.

Now, what kind of ram chip ur using? if u dont know/not sure, i suggest u to test the maximum stable ram speed for ur ram 1st. Most of Corsair's 667 are not capable of running 400mhz even @ 2.3v. So try it 1st

read my previous post if u dont know what im talking about.

wah... my opinion leh... get better PSU... i dunno y but i juz don like MSI... but aussies love'em... u should increase ur RAM multiplier and voltage... as for ur GC i not sure but i don think 5500 has any OC capability...

yup...i've read quite a lot of discussions about the micron d9 chips...
i do know that...

im using the asus silent knight which i just bought at kl pc fair. my ram unfortunately are not the OC-able ram chip. maybe i can just tweak it a lil bit. thanks for the advise

how's the silent knight performance?

pretty good actually. max load temp not exceeded more than 57C and as for the thermal paste im using as5.

try oc it kaw kaw and see the knight is fighting hard or not?cause it seems that it has no good feedback in the review....but i know it looks great!

well,it keep restarting and back to stock setup?it's because ur setting is out of one hardware limit,mostly ram since those relabelled ram is not really good in oc,but maybe is ur voltage control is not good,try to increase some vcore and vdimm to improve stability.it should be ok now.
