Exactly. That's why in the world of OC, you need to find out the max OC for each component.

tRD = tRAS = tRA = Row Active Delay. It is a RAM sub-timing setting, usually quoted as the 4th parameter i.e. 3-3-3-9

Wow! This is the first time I've seen a mobo that cannot change vcore. Looks like it's true. Look here : http://global.msi.com.tw/index.php?func=pr...no=170&cat3_no=

Did you try any other software like Rightmark CPU clock?

1st time posting here. just oc result, no prime95 ss, dont think it will pass..



using cheapo asrock 865GV mobo + KVR.. didnt expect to hit this.. haha..

Errr... I don't think it is stable. Look at the cache readings - L1 Trace is showing "12 Kuops"???

so, what's the stable value? me still noob at OC..
just trying mild OC to test how far it can go..
huhu..

U can boot at that speed with cheapo mobo already amazing lor. Try SuperPi 1M at least.

still noob in oc
tried to google after reading your post, don't know how to use the cpuclock utility
b4 this tried to use msi corecentre, it shows N/A there

edit: it shows both in grey for multiplier and vcore, i guess its really locked kao kao

You need to stress your rig to see whether it is stable or not. Some stress programs are Orthos and OCCT.....



OIC, maybe get a new mobo?

u try dl the latest cpuz . sometime the cpuz had mistake reading ..

targeting dfi infinity dark, but the price my whole pcfair salary also insufficient for it
somemore now got ppl doing bulk for E6750 and E6850, the price is too temping,duno which to go for 1st

screenshot at 195FSB + superPi 1M. 196FSB seems does not stable, keep restarting.

i saw most of the overclockers will set their multiplier lower unless its locked (example : pentium D 805)

anyway, what kind of cooler you're using? if stock you better don't go further

Quite impossible but that wht he did. are_keem, list out ya rig spec on ur sig..

865GV kar... try to set VCCM and another 1 or something like tat in BIOS to high and see wat wat happens... i used to reach 4.6GHz wif Celeron D347 wif it... Orthos can last for 20min... well.... at least...

oh... how noob i m... damn...

Finally had a chance to test out my new rig.

On my P35-DS3, I'm stuck at 475mhz bus speed. This is at stock voltages for everything including vMCH.

No matter what I do, increase the vMCH, vFSB, vPCI-E, my mobo would hang at 480Mhz. I even tried jumping directly to 500Mhz but not successful!

Any ideas how to overcome this 480mhz wall? Or is it my CPU wall?

probably, your MCH and/or CPU needs better cooling. Don trust the Hardware monitoring, touch the NB hsf and it burns your finger, telling you it's impossible to be 41C

If u've not known, the P35s from giga will do 500+fsb @ default voltages. even on stock volt..it's burning hot, so it's not a gd idea to add more vMch.

Ya. I did touch my NB heatsink. Not burning la, just feels warm. (Oh ya, my rig is naked! No casing.....)

I was googling around and found that the E6x50 series may have a CPU fsb wall of 490Mhz. Could be because of this reason. Anyway, will have to wait for my new CPU heatsink first, I guess.

Did you remove the thermal gunk on the NB n replace it with AS5 or something? Weird, mine is burning hot, cant put my fingers for more than 3secs. I've replaced it with AS5.

No. I didn't remove the NB.

OIC, you're using the S3L. Mine is DS3. Slightly larger heatsink, but nothing compared to DQ6!!!! See pic.

the cooler? thermaltake big typhoon VX @ 1500rpm, less noise.
about the multiplier, I think it is locked.
cheapo mobo mah, not many OC features.



this is my humble pc spec :

intel pentium 4 506 cooled by TT Big Typhoon VX
asrock 775i65GV
kingston 512MB value ram
msi geforce4 MX440
WD 80 GB SATA
acbel i-power 450W.

U already have nice cooler and PSU. Upgrade ur RAM,cpu, graphic card would be enuf for gaming.

hehe.. i'm not a hardcore gamer..
also not a hardcore OC-er
anyway, lots need to be upgraded

Guys Guys, this may sound really really really n00b, but seriously, i really have no idea how to manually set the dram frequency for my mobo..

the only way to "set" is by changing the fsb:dram divider thing.. and the least i can set is to 1:1 ratio.. thus, the dram freq will always be equal to fsb freq, i can't make the dram freq lower than the fsb freq

so kmarc, as you said, that i need to find the max my cpu can oc without oc'ing the ram, how will i b able to do that, as when i oc my cpu, my ram get oc'ed as well? loosen the timings really really goddamn hard? or anything else u can teach me? i will be very much appreaciated..

The lowest divider is 1:1. There's no way you can Overclock without overclocking the ram. Set your ram to CL 5-5-5-15 and raise the CPU Fsb.

Errr... but you have the P965-DS3 mobo wor.... Can't you lower the rams from 800Mhz to 667Mhz? That should be possible, because if not, how does this mobo support DDR2-667?

I never used the P965 before but maybe you can ask in the P965 thread on how to set the rams.

If that is not possible, there's 2 alternatives:
1) As kuchingfight suggested, loosen your rams to 5-5-5-15 or even higher e.g. 5-6-6-18
2) Find the maximum ram speed. That way, if you max ram speed is 500mhz (i.e. DDR2 1000mhz), then at least you know that you are nearing your limit if your bus speed is nearing the limit for the rams....

same here for my boss rig... using E2160... most stable is 400x8... 500x6 can achieve but not stable... super_PI 19sec though... my E6300 did 18 for 500x6...
only thing i did was increase voltage... and most probably need better cooling... electronic component work better on lower temp due to lesser wasted power and lower resistance...

wow..500fsb on E2xxx is indeed something new to me. Suprisingly the FSB wall hasnt come in place.. possible to add a CPUz screenie?

Yeah, no wall meh? My CPU has hit the wall so many times, dunno how many bruises adi....

Once hit 480Mhz, straight reboot.... Will try higher vcore later once my new heatsink comes....

y upgrade if u not into gaming and OC...? good enough wat... u might have loads of issues wif graphic cards though....

it supports 667MHz rams, coz, initially, all processor don't have fsb that exceeds 333MHz, rite? we are the one who oc'ed it to more than that.. that's where the problem lies..

the lowest divider *IS* indeed 1:1 in Gigabyte 965P-DS3 mobo.. thanx for clarifying it kucingfight

i think my proc reached the wall larr, coz when i put 500MHz fsb, i already set the rams timings to 5-5-5-15...

sigh, i think i'll work on this more this weekend.. im kinda busy now..

yeap, so did it boot @ 500fsb? it's kinda hard on the tiny NB cooler, perhaps u need somethin better like Noctua U6. The P965 chip is burning hot. also, which HSF are you on?

sumtimes feel a bit laggy liao..
haha..
anyway, what is that VCCM and VDDQ means?
I saw them in BIOS..

edited : double post

so how max stable urs proc doin now?primin orthos for how long?try burn in ur proc n ram 1st..perhaps later u can try higher

seems like voltage to me... for RAM & proc...?
did tat solve ur unstable prob....?

ur E6300 running 24/7 on 430x7 kar...? i set mine to 400x7 @ 1.28V cuz of temperature... dowan to shorten the lifespan of my proc... later gonna try Celeron 420 pulak... i reach 533 b4 but cannot last for more than 1 minute in Windows... i think my RAM bottlenecked it... cuz my RAM is DDR667... my RAM can't go beyond 500MHz... later gonna get Mushkin DDR800/1066 C4/C5 2GB kit... then try to break the wall...

Wah! Why Mushkin in particular? Are they cheaper?

it boots on 500fsb, but orthos not stable 3 sec and i got a hardware rounding error. my HSF is intel stock wan. planning to change, at the moment eyeing the TT Big Typhoon VX. Apart from TT, what other HSF is good ah?



yeah, 24/7 on 430x7, but then Vcore i put 1.1875V! it seriously can boot and can even orthos more than 6hrs stable.. my temp is around 50c idle and 58c load. Yeah, i wanna change my HSF..
and yeah, why mushkin?



max stable not sure, probably 430x7 lar, orthos 6 hrs lebey no prob..
when i kick my fsb to 450, orthos will get the 3sec hardware rounding error..
Think my temperature is the cause ah?

PS: edited, Vcore at 1.87V mmg gila lar

maybe..
manage to boot up at 198fsb but stuck at windows welcome screen.
196fsb also not stable enough.

yeah its better to change to 3rd party hsf when on oc..geminiII,noctuacan consider as gud hsf..u can try up abit ur vcore then increase abit ur fsb..if 500 cant prime stable, try lower its abit..myb 495..oc need try n error to find ur stable fsb ..gud luck

yeah, when i oc higher, i increase my Vcore as well, i'll set to default, i.e. 1.325V.
Even at 450MHz already get that error..
see larr how, i think this weekend i'll do some more trial and error.. atm kinda busy..

u guys ask me y mushkin...? cuz Mushkin got the best value for D9 Micron chips... and they are well known for their higher bandwidth + lower timings at the same price... their value DDR400 RAMs are rated 3-3-3-8 at stock... and cheaper than current Corsair and Kingston summo... but Value class no D9 chips la... only shawty has value chip wif D9...
still waitting pricelist from supplier... wanna know bout the XP, HP and Redline series... the EM series sold at Low Yat are the Value performance RAM...

btw t3chn0m4nc3r, can show us the CPUz for e2160 @ 500fsb?

boss sold tat board d... now waiting for new arrival... hang on... but it's not stable...

well OC without increasing voltage wif FSB more than 180 is good enough already lor....

Hey at least get a Pentium D and add more RAM. And if sumtimes boring u should get at least 8500GT or 2600PRO.

---

Added on August 1, 2007, 8:21 pmBut u using AGP i think, so need to wait for AGP version of 2600PRO...

that's the drawback.
anyone wanna trade in their procs with mine?
haha..

hi guys...
i jz got e4400 and p35-ds3 board...
do i need to disable speed step to overclock high fsb?
me new to intel...

YEs disable all the features, EIST etc etc

my friend is getting his C2D 6550 + Gigabyte P35 today... hehe
