i tried 445 = 4.0 with 1.3vcore and tried orthos but computer froze after 2 min now i tried bumping the vcore to 1.32v and it only ran orthos 4min then gave error, ive been doing the Blend - stress cpu and ram test...

[PakaPaka]

my first overclocking
i oc some old p4 but without vcore option in bios :-/


http://valid.canardpc.com/show_oc.php?id=463670

Vcore - 1.328V
Bus - 450, 1:1
Memory - 900MHZ CL 5-5-5-15 2.1V

Stable 24/7

how it looks?

[Vatos_locos]

what is the Vcore/Vtt for that ?

[PakaPaka]

Vcore 1.328V
and i dont touch the Vtt, you told me do not touch it! (in some thread i open, not you.. somebody but not you )
that's why i cant move up than 470mhz Bus??
even in ratio 7.. and high Vcore..

[Vatos_locos]

lol finally did i told about the Vtt :p ?
ok seriously 1.32 is good for the C0 stepping eny chances to know what is your batch ?
Vtt is auto @ bios ? if yes try the lowest setting that you are stable

[PakaPaka]

what the vtt give me?
why to try the lowest setting for it?

?

what is batch? :-/
i don't what is that..

[Vatos_locos]

my English aren't so bad but i didn't understand anything

FPO/batch is on the box of the cpu or if you don't have it it's on the cpu

as for the Vtt i didn't understand what you want to say i'am sorry

[Godmyster]

For 4.2GHz you need to increase the FSB to 467MHz, but I'd go a little at a time. Try 445fsb for 4GHz first and they see what voltages are needed.

I tried now 4.0@1.36v and orthos ran for 1hour (did the small ffts stress CPU) then froze windows damn whats wrong here? do i have to give more vcore LennyRhys?

lol...

so i have the intel cpu box, how its write exactly?
OH!
FPO #: Q817A283
Pack Date: 07/22/08
Version #: E27439-001
Spec: SLAPL
what is that mean?
good cpu?...

Hello guys. Going to swap my old E3110 with C0 stepping on E8400 E0. But which FPO (BATCH) is known to be the best?
Thanks in advance, guys!

I dunno, it could be your chipset, it could be your memory, it could be your FSB - it could be a lot of things. Unfortunately there's no easy way to overclock; you have to tweak things a bit at a time and then refine them when you get it stable.

How much vcore can i go up to with air cooling? (Xigmatek S1284C)

[Godmyster]

Whats wrong here? i dont know what to do i put vcore @ 1.32 and its not even stable at 3.9mhz my memory isnt even CL 5-5-5-15 its CL 4-4-4-12.....

[The Viper]

Godmyster, Im also struggling trying to get Orthos Blend stable on my E8600. I dont know how old your memory is, but if its going bad, relaxing the timings wont help...run memtest, test 5 to make sure the ram isnt faulty. Anotrher big setting for Orthos Blend stability is MCH Vcore, try raising that and see what happens.

Witch memtest are you talking about? the one you have to boot with a cd? and MCH Vcore what is that?

Thanks for the response

PS: these are my memories - PI Black G.SKILL DDR2 PC2 6400 CL4 4GB Kit link -> http://newgskill.web-bi.net/bbs/view...esc=asc&no=126

[The Viper]

the one where you boot of CD. Some people use the memtest windows version, and say it is better at picking up memory errors. MCH voltage is also known as the NorthBridge (NB) voltage, and definitely needs increasing when you raise your FSB to certain levels...check in your BIOS and see if you see that option, and raise the voltage.

[Godmyster]

My NB voltage is @ default how much should i raise anyway?

[The Viper]

I couldnt tell you, every mobo is different(what is ur mobo?)...just start raising it, I would go a few notches at first, as ur pretty unstable at the moment

[Godmyster]

i got a P5Q Deluxe but i dont even know what the default is since its on auto, any good program to read voltage in windows?

[WeldZilla]

I have been pouring the volts to 2 e8400's since January 21,2008 and January 28,2008.
Neither proceessor has seen less than 1.518 and both have seen well over 1.6 about 1/3 of the time
One has resided full time on my P5E and the other has split time with my P5Ke- wifi and my P5Q-Pro
the P5Q-pro is well just no where near my idea of a great board. Actually I hate it on many levels!!
Yesterday I decided It was time once again to torture my e8400 with some benching. So I cranked it up!!
the processor was running at 1.675 in the bios on my P5E but as you can see it will be much less in reality
the cpu pll was set at 1.72 the NB was set at 1.7 and the mem was set at 2.22.
My 260GTX on Aquamark was crnaked to the freakin max!!!.
I have a liquid cooled processor but stock air on the 260GTX. I pump cold air into my case from outside via the
radiator so it is Xtremely cold in my case. as a matter of fact my freakin case itself is freezing!!
my case is actually 38.9F right now. My radiator temp is 29F my G.Skill memory is 44.1F I use a temp gun on everything!!

Here is what I did yesterday . these are my highest scores to date at my highest clocks. So I can tell you after 11 months there is no degradation
happening with my chips!



As you can see a little cold air helps kick my completely stock vanilla MSI 260GTX right into overdrive!!


I should have an e8600 but Stalliontek sent my a 7300ES instead!! They just got it back today so when the refund shows
I am going step up to the 8600 and shoot for the stars with it!!

The P5E coupled with G.Skill 6400HZ memory and this processor has been the beat system i have EVER owned!!

[LennyRhys]

No degradation at 1.5v? Maybe I should go for 4.5GHz 24/7 after all lol, but it's more of a motherboard issue than anything else lol.

[WaterFlex]

Guys, can you help me with my answer on the previous page?

[LennyRhys]

It doesn't matter what batch you get... if it's an E0, it'll most likely be a monster overclocker. I would however recommend getting an E8500 if you can do so without breaking the bank - the 9.5 multi makes higher overclocks considerably easier.

I was directed to an online retailer which is selling E8500s labelled E0 which conveniently takes the guesswork out of the "which stepping" problem, so I just bought one without thinking of FPO/batch or VID, something I wasted too much time doing earlier this year with Q6600s.

And the result? I have a great chip which will do 4GHz on 1.23v and at my current settings of 4.4GHz on 1.35v the load temps are 47C tops.

Short answer: If it's an E0, batch number isn't really important, neither is VID.

Thank you, bro

[LennyRhys]

Pleasure. Now get to it! :P
