tampoi... heard tat u got ur DS3 and ur E6300 edi... how was the overclocking result??

Just finished installing Windows in the early 3AM and have get to work in the morning so not really ready yet.... Sigh, will try to work on it tonight

Great, am too agrees on starting a new thread for Overclocking Result as currents one are more based on technical and discussion.

tAmp0i, tonight ah.

LoL. I'll try 'cause the TwinMOS-fatbody-wannabe-ram rated at 266MHz 4-4-4-12 could be the letdown

400FSB X7 so far...stock voltage..

Hey kev, lol i get the same screen as yours in the boot screen (66x7) while installing the Windows F1 bios

wah.. tamp0i.. got your proc liaw ah? wow~

Kev, where's your E6700 ES?

hey tampoi....fast clock liao.....we're wait here.....give us a best resault....

Played with it... But not very Ocable.. Can go until around 3.5Ghz on stock voltage..
DS3 not suitable for E6600 and E6700

Love E6300 more....

tAmpOi : I using Hyper 48

Corrected
Now with the valueram, can't reach DDR667 even with loosen timings.

1st pic) current most stable : 428x7 @ 2996mhz stock vcore, ram @ ddr1070. dual PI 32m

2nd pic) current highest clock : 450x7 @ 3150mhz 1.35vcore, ram @ ddr900.. super PI 1m & sandra cpu arithmetic

Gu, ya got the proc liao but just got the mobo only.... Post your ES here liao

Irenic, what is your Vdimm set in bios? Normal? Still pairing the Corsair value?

yups @ 2.2vdimm .. tomorrow i'll get a new ram which i doubt will work better than this ahaks.. but hopefully not worse

irenic, How much mch voltage u up? Cant really go beyond 400 without upping mch volt... Pass super PI 32M but not very stable also...Suddenlyrestart pc....

Pr is it the northbrige overheating?? Plan to change it to Blue Ice 2

vmch +0.2v .. i dunno bout the northbridge temp, but my pc also hang last nite when i was running dual prime @ 450x7 with surfing + listening to mp3s..

wait for someone back from KL.. cos he bring to KL mah.. sure will post...

Why DS3 not suitable for E6600 OC har? I am buying E6600 next week when the stock arrives but still don't know which mobo to use...

@tampoi...nw i jz knw ur mirian... mayb i shd visit u n hv a look at ur conroe
btw who u bought it frm?

@irenic
wat ram u replace ur corsair vs?

looks like ds4 perform better thn ds3 ah?

not so.. bcoz some of this combination prevent e6600 from using 9x multiplier when oc

Lol.... Anytime you're free Bought it from kev_neville

Then maybe one can lower the multi of e660 to 7x or 8x?

http://www.xtremesystems.org/forums/showthread.php?t=107892

7x multi with 499FSB on air.

yups u can lower it down.. but then whats the different from getting e6400? owh the 4mb cache? well it's up to u if u think rm400 is worth the extra 2mb cache

wootz since i getting my X6800 in a months time, time to start discussin with u all

how much is the Gigabyte board?

wic one? DS3? DS4?
DS3 is 500++
DS4 is 600-700

nice! where did u order it and how much?

woot.... Those still too pricy for me... still got wait till the price drop...

E6400 is same as E6300 with 2mb cache. Only E6600/E6700/X6800 have 4mb cache.

i know that. thats why i said, if u wanna run E6600 on ds3, then when oc u need to use 8x since it got problem with 9x (some of them) so it just like u r running E6400 with 4mb cache.. i hope u got my point

Yea, get what you mean from there.

Yet to see more results.

Guess E6600 would go better with Bad Axe or the Asus P5W DH Deluxe. Both are equally pricey.

how come everyone is usin gigabyte boards for this proc ? is it the best one in the market right now ?

most affordabel man

not just that. but also one of the best so far..

hhhmmm u noe, i tot u wud had gone for the X6800:p
u are liek the org kaya of LYN man!
hehe

anyways, back to the board, i still feel asus is doing slightly better, but it needs abit of mods here and there. so i guess thats the turn off,. and the price of course. killer

x6800 is way too expensive for me dude.. if i buy that, i have to eat maggi for the rest of the year

btw i was considering between E6400 and E6600, bcoz the extra 2mb cache was really interesting but then when i read review comparing 2mb vs 4mb core 2 duo, the real time difference is too little to make it worth rm400 extra. So i decided to buy E6400 but then no stock. So had to buy E6300 which i am really satisfy now

E6400? Is it because of the extra x8 multi? I think you'd better gone with the E6600 straight away if the extra 2MB is really kickin off

hmm well bcoz i rarely buy the lowest proc in each category not bcoz underestimate them but bcoz i like to run stock for 24/7 .. and 1.8ghz looks a bit slow for daily use hehe

but it seems like i can run 3ghz for 24/7 with this core 2 duo hehe

neway this is my new ram.. mushkin ddr2 800.

Hello 20 seconds Found the stick alone in the rack thinking of giving it a fly.
Only 1 stick of Kingston valueram DDR533, Vdimm +0.5, Gmch +0.2v, Vcore normal. Not bad for a DDR533 though


Attached thumbnail(s)

that's great tampoi! seeing u easily getting 20secs with 2.9ghz & ddr830 ram make me eager to format my windows

Make a new partition for benchmark only, clean and clear

i did that last time. create 7gb partition with a fully tweak win xp.. but now no more space since i have both win xp n vista installed

Remove Vista, install fresh WinXP. Kekeke.

so sayang to uninstall the vista.. hehe it looks very nice

btw i just looked at my oc database, @ 2.8ghz, ram @ 1000mhz 5-5-5-15 i managed to get 20.437secs in super PI 1m, while @ 2.99ghz, ram @ 1070mhz 5-6-6-15 i managed to get 19.344secs.

now with cpu @ 3.15ghz, ram @ 900mhz 4-5-4-13 i managed to get 18.406secs..

is that mean cpu clockspeed is more important than ram fsb in super PI ?

Hmm yes, in the world of PI CPU clockspeed matters most.... Timings come second and then OS

Wahlao..Fast sia..Anyway,irenic,what's the highest clockspeed ur 6300 can go?

irenic...hw much u got ur mushkin?
this E6300 seems kick ass....3ghz....tats a lot of gain in oc!
y dun u try loosen the timing more n get the highest fsb..mayb can c some nice super PI calculation....

This post has been edited by siauann: Aug 2 2006, 01:36 PM

i think it won't help much... tight timing is better in superPi rite?

If 3.5ghz with looser timing, still faster than 3ghz with better timing in PI calculation.

Not really, changing timings from 5-5-5-15 to 4-4-4-12 doesn't do squat to my superPi. Anyway, here it is: 17secs with stock vcore. Once I am able to modify the vcore, I think I could go beyond 3ghz.

this shows it all. i dont think my windows is too bad. bcoz different between E6600 and E6300 is 2secs, and thats true in Super PI.

However, I do see a difference in terms of amount of L2 cache. 2.88ghz with 4MB L2 can get lower times compared to a 3ghz ++ 2MB L2 cache E6300. If the E6600 can run at 3-3.3ghz and above, I think 14s is not impossible since every 100MHz increase roughly translates to a second off superPI.

i kinda agree wif wat Hyde`fK says so does jarofclay says.....tight timing doesnt play major role in gettin better super PI score..... the higher ur clockspeed is the faster the super PI time...

This post has been edited by siauann: Aug 2 2006, 11:53 PM

Yea, still yet to see anyone can reach 3.5ghz on air yet. jarofclay should have the nearest answer to it as he owns a E6600, which can easily reach 3.6ghz with 400mhz.

But does E6600 clocks well compared to E6300 right now?

Problem is the Intel D975XBX doesn't allow adjusting the Vcore without any modding. Fear not though, X6800 is on the way and with multipliers enabled upwards on 975X chipset, I think 3.5 and above might be achievable.

What is the memory though? The strength of 4MB really shows

yeah. it's normal to see at same clockspeed, 4mb c2d will beat 2mb c2d with 2secs in PI. few people who owns both conroe and allendale has tested it and most of them have same result.
i guess even my windows is fully format, i can just get extra 1 sec max..


yups. E6600 has better chance to hit 3.5ghz since the multiplier on E6300 is quite low. But for 3.5ghz, i believe is just a matter of time for all allendale user. As for me, I'm always strive to hit max stable oc. I wont rush into finding max clockspeed but just be able to take screenshot

So far max OC for conroe is extra 300mhz over the allendale.

just grabbed the last unit of Core2 Duo E6300 from ALL IT, other shops all don't have stock, or want to sell as PC bundle only.

Now testing at friend's house, not yet back to JB house.

Test Bed:
E6300 SL9SA B2 Stepping
Gigabyte DS4
2 x 512MB Micron D9 DDR-2 533 @ 2.3v
MCH Voltage +0.2v
ATI Radeon X300 PCI-E
Dell 250W PSU

Currently doing pretty stable @ 2.8GHz 7 x 400MHz, RAM @ 800MHz 5-6-6-15.
Will stress test again when I back home.

Hopefully my SCSI MegaRAID PCI-E card can work well on the 2nd PCi-E x4 slot of the DS4 Mainboard.

Will take actual photos and do a comprehensive review about this rig later

Pass 32m superpi.. All stock voltage..

Cool, 18 secs.
Keep it going.

Ehhh, why the stock voltage is shown as 1.31V?

Isn't it 1.31v? What readings you got?

Luckily, I got 1-to-1 exchange from C-Zone. But too bad, they only have stock next week..

If you check my screenshot, it was 1.175V stock. Let me check some documents on what's the correct default voltage.

omg? You guys are seriously pushing Conroe processor from 1.8 to 2.5????? I didn't know it can go that far! That's like 40% increase of speed?

Wow.. I can't wait to see what my E6600 can do this Sunday.. oh god. I'm getting an orgasm already.

CPU-Z fluctuated, try check it with Intel's software

Lol.... Welcome to Core 2 Duo family

Wah..Austin kaya sia..How's ur laptop business lately?

34K in 3dmark01se with just an 8 pipeline card! Unprecedented!!

That's raw!
By the way, did you guys noticed the Windows loading bar during startup? I felt mine was quite slow, about 6 - 7 times compared with Opteron which is just 0.5 bar last time....

yes, mine is 4 bars now, dunno why....
Tried on A64 is 1 bar...

i tot austin got sell E6300 bundle wif ram? y need to get frm shop also?

u dint knw those 1.86 can push more thn 2.5 oso kah?

yeah somehow this c2d is slower during win xp bootup. but in vista, it is much faster..

i thk it doesnt matter rite? as long as its fast in other application n gaming n other purpose....

hehe that day I thought I don't want to upgrade but then the performance is so tempting, so I had no choice but had to buy from ALL IT cos my stock also all sold already...

Some photos of my C2D rig... casing just being repainted.

wah.. look-new-case for ur new c2d !! great job!

i m considering between E6600 and E6700..... which one u guys will oc the best??? since it just launched...i only able to see those ES chips results around.... anyone have any idea which i should go for???

lucky my psu didt burn... if not i wil kill u

anyware... nice oc result u hav

i bet both will have same limit. so go for 6600 so u can spend ur money somewhere else..

by the way while i was studying for tomorrow quiz, i ran a continuos benches without reset windows or tweak anything to test stability with the new release bios for gigabyte mobo.

dual super PI (from 1m till 32m) -----> 3dmark03 ------> 3dmark05 ------> 3dmark06 ------> 3dmark01se ------> aquamark .

ive tried wit easytune5 to oc until 300Mhz (default 266)...yea no problem...den i reboot and i chk again wit cpuz and spi run...it seems like reset back to default...=/
1. is dat wad easytune use for? it will reset to default after reboot?

den i tried on bios...i tweak the clock from 266 to 270 (for testing)...it rebooted twice and went in windows...den i chk with cpuz and spi run...still the default speed =/ but i chk in bios yea is tune to 270 d worr...im real noob in dis =/
2. can gip advices and xplain?

for ur info:

intel c2d e6300 stepping 6 rev 2
ga-965-ds3 F3bios rev C1
kingston ddr2 667 1gb x 1
coolermaster xtreme power 430W
galaxy 7300gt ddr3 128mb

first of all, it's better if u post in this thread
http://forum.lowyat.net/index.php?showtopic=320359.

anyway regarding ur questions,

1) yeah easytune does reset ur setting everytime u restart the windows.

2) this intel core 2 duo does have EIST, if i not mistaken stands for enhanced intel speedstep tech. during idle, it will slowdown ur clockspeed to save power.

well...lets say money is not an issue for this will will u go for????ppl are using quite low fsb on E6700 compare to E6600 as they used the multiplier to boost up the clock...but the one i m buying is not ES version so the multiplier is locked at x10....
