i did try running 333x10.5 with auto Vcore, tat shoots up to 1.31V shown in cpu-z..

as i mentioned earlier i set my Vcore to 1.28750V to get a stable 333x10.5..

do u remember how much is yr voltage when u set it auto?

about the psu i think like not enough..
1.35 vcore can reach 3.8??
damn..so many time try..FAILED
i oso try to increase a vcore n oso FAILED

my oc data..

Added on September 4, 2009, 1:13 ami hear that never set to auto vcore bcoz i maybe can reach a high vcore..
is it rite??

are you sure your +12v is 10.++v? it's too low i think..it should be 11.4v-12.3v....

For my previous 334 x 10.5; I think it was around 1.26v, with v-droop it was 1.242v in CPU-Z.
Plus I was using Artic Cooling Freezer Xtreme that time, maybe the low temps contribute to my stability @ that vcore settings.

Just to remind u i used that setting bcoz thats the maximum ghz you can get if you use DDR2 667mhz ram to get that 1:1,
now i'm using hyperx 800mhz, my usual preset of OCing is: 3.4ghz, 3.6ghz, 3.8ghz, 4.0ghz, etc.....

These days I'm experimenting on how much FSB can my mobo handle, (ASUS P5QL-Pro) latest trial is:
FSB 420 : DRAM 841mhz (1:1), i have to increase the hyperX from 1.8v to 2.0v to be stable, but fails at times..probably because to changed my timing from 5-5-5-15 to 4-4-4-12...
Still in the experiment phase though..

what +12v mean..
n how to make it higher bro..

what i know la..+12v rail is for psu stability...more +12v droop mean not stable..correct me if wrong opinion about this...

p/s: what is your psu using right now?sometimes the software give wrong reading..better check in your bios...

it all about psu la..
im using CM EXTRME 460..
need change ? to better oc

There's two version of CM Extreme 460; one is the one u'r using currently and 2nd is the newer one : CM Extreme 460 Plus
the 'CM460 Plus' has revised railings for the +12v since the older version has encounter lots of problems in term of railings and low true power output..
as low as 430w-ish of true power if i remember..

Yes your +12v is pretty low, should be at least 11v minimum, 11.8v average.

from my experience bro..actually i'm also using E8400 E0 stepping also but need high Vcore (1.38v) to make it stable at 4.0ghz ...if you can see majority E8400 E0 stepping can do 4.0ghz with 1.28v without problem...even i used TX750W psu...so it's depend on your proc & luck also...

mine is xtream power plus..
i will try that..

If its Exreme power plus, then the problem might be elsewhere.
(i'm not an electrician, but u'r +12v is STILL pretty low, probably i'm just wrong about the CM 460Plus,
maybe the CM460Plus hasnt improve much on its railings... hope any other CMextreme+ users can clarify me on this)

But of course still cant ruled out the possibility of PSU insufficient power output.
I think you should try very troubleshoot possible before deciding to buy new PSU's,
but if u got the $$$, a new PSU is somewhat recommendable and a good investment in the future u want to upgrade hardware bro

really2 luck bro..
normally i see E8400 easy oc to 4ghz..damn..



i oso think to new psu n grapics card..
maybe nxt year..no money rite now..

p/s..i try 3.65ghz with 1.36 vcore..stable..
about 12v--still cannot solve..still at 10.++..hahha

3.65ghz, whats u'r FSB now??? If its 400 and slightly above, then its good when running with DDR2 800. I think when u were OC'ing @3.5ghz, u downclocked u'r DDR2 800mhz DRAM to 678mhz-ish, which i presume might cause some instability. Maybe all these time the problem has to do with the Dram freq., not the Vcore because E7400 @3.5ghz does not really need to be push up to 1.35v...(maybe those unlucky chips might have to)

When u'r using DDR2 800, its recommended to OC u'r CPU to: (IMO )
3.4ghz (400 x 8.5)
3.6ghz (400 x 9)
3.8ghz, (400 x 9.5)
4.0ghz, (400 x 10)
etc..........
^^^This is a common baseline for overclocking CPU with DDR2 800. (without needing to OC the DRAM) Later u can fine tune...
And as a bonus you obtain the FSB to Dram ratio of 1:1

With the FSB maintain at 400,(or slightly above) u dont have to overclocked/downlocked u'r DRAM frequency.
When OC'ing DRAM, usually need to alter the DRAM voltage or choose a compatible settings for 'clock twister' for stability.
e.g. my DDR2 is at 820mhz(410mhz)@1.9v; or 840(421mhz)@2.0v to remain stable.
But right now i'm on stock 800(400mhz) @1.8/AUTO.

Yeah the amps of the railings u cannot do anything about it once you bought a PSU.
But i think u'r PSU is good enough when u are currently using 9600 GT.
(FYI, 400w of real power and 26Amps on the 12v rail (combined) is more than enough for this card)

HD4850, 4870, 9800GT, GTs250, etc.. has drop its price significantly these days, just FYI if u'r planning to get those GC,
u at least need PSU with 500w+ of real power; 600w+ real power for SLI and C.Fire

Anywayz, try playing around with those settings i recommend above and report back bro,
bcoz these are valuable data/info for all other E7xxx users to read.

omg.. talking about 12V+, i juz check mine, it just show 1.0V+ and sometimes not showing.. y ah?

software bugs maybe..what software you using it?

try everest ultimate edition latest version...

for me software just reference only..but i trust the reading from bios...

HWmonitor n Everest oso show same reading.. sometimes 0.06V then sometimes disappear..

will check in bios later..

BRO..I CANT SET TO 400 X 9 FSB..
IT WILL SHOW PREVIOUS OC IS FAILED..
EVEN I SET fsb to 400 x 7 is oso failed..

one more, is it ABIT IP35-E about 150 is worth to buy??

maybe you need to update with latest bios...

Man that's unlucky It's the mobo...

ABIT IP35-E is RM350 brand new @LowYatPlaza, The DFI i reccomended earlier is RM340 @LYP. If u got the cash, there's another P35 mobo, buts its consider expensive if u'r in a budget:
MSI MS-7345 P35 PLATINUM (2 PCIE=Crossfire) @RM490 LYP.

Its doesnt always have to be P35 bro, u just need to find another P43/P45 mobo, e.g. like Gigabyte EP43-UD3L, Asus P5QE,
Jetway JXBLUE-P45(this one fetured in Goldfries's review on OCZ 1.2ghz in GameAxis magazine) Asus P5P43TD (DDR3), Biostar TP 43, etc...
(all the mobo above budget less than RM350)

or if u feel lucky u can go hunting in LYN garage sales for a bargained price

juz check in bios.. it shows 12.429V.. phew..

anyway, +12Va with 18A good enuf?
