so even if u oc a bit also will cause the weird restart?

HI, want to ask what is the best revision for Q9400 in term of oc. tq

yes. very worrying rite now for me after i knew its not a normal thing.

The only time that it will do that is that when u have an unstable oc. if it's unstable, it will do that 2 sec turn off thingy and reset to default bios setting, well that happened to me at least. But I have a feeling that u haven't done enough for your voltage part. when u have 400mhz for the fsb, u will need to increase fsb voltage (maybe up by 0.1v or 0.15v) and preferbly set the vcore manually. in your case u said u set it on auto, normally bios' auto won't be high enough for any oc. i suggest try pushing it up to 1.3v and give it another try. how about your ram? what timing are u on? CL5 or CL4? what's your voltage for your ram? btw, turn your performance to 'standard', do not use turbo or extreme etc. u really need to make sure all those are set up nicely. and most of all u need to know what ur doing!

restart ehh?
yup, u should lower the vcore...
and dont forget the ram timing and oso the vdimm...

Well, New Q9550 C1 user reporting in,
now i'm using stock fan, stock clock, the temps are
idle 53/35/53/49 ....wat a wierd temps, load is 74 /60 /70 / 62

why is the temps so special one?

Dun take it seriously. Bad DTS.

-pWs-

i finally got my Q9400 stable @ 3.8ghz.. 4.67v in bios lol crazy >.< (4.44v in cpu-z) on air xD max load temps were 72C (intel burn test) and 66C (prime)

i hav tried bump in some vcore manually and folow ur advice on the other settings but to no avail. my pc still hav the problem but prime95 got no errors for 2 hours. ur rite, i cant really figure it out = dont know wht i'm doing.

nice

now to go to 4 ghz.. probably will burn my CPU lol

Its normal, my Q9450 is running at 3.2ghz using 1.2vcore has 54, 52, 49,49 on idle. hahaha

What voltage is that? 4.67v?

Ermm. I dunno you got q9450.
Come exchange w my q9300.

-pWs-

lol 4.67V in bios >.<4.44v in CPU-z (with vdroop i guess)

Typo error I guess, should be 1.XX for the vcore.

-pWs- : Here's my SS



Ur Q9300 oso power oledi

wow nice chip u got there >.<" 1.18v on 3.2ghz.. i think u can push it 4ghz++ without hitting the 1.365v (thats what intel said) wall yet

The speed here is not the max yet, previously tried 3.45 on the m2f for my customer's board, but his value ram is stopping it from going further. I noticed this was a good batch, the "B" batch, so had to decide quickly to get it. Using it on a DFI P35 DK now.

hmm how do u check the batch anyway?

its stated on the box. On the proc also its written: L8XXAXXX, the "a" can be "b" which i read in some forum saying the "b" batch r better for oc, not sure how true, so i just try my luck.

Check this out



power of SFF

maybe as pws said, the sensor or Q9550 are mulfunction, i try to touch it with my finger..... not hot at all =_="

but i don't no how to oc using P45 JR

someone teach me pls~~~

my latest test for my Q9550.




Will try 4GHz later.
