Failing To Post? Any Reason Why?

Ive recently got this Processor, and can get it up to high clocks so far about 3.4 on stock volts but sometimes it decides not to post? Why is this, ive never encountered this before with any other CPU.

Currently at 3.2 because it seems to post everytime on this clock.

Details of what i have in sig.

Josh

EDIT: Title supposed to be Failing... Could some nice person correct this :)

The person i got this off had it at 3.5Ghz on stock volts, if im lucky i can boot up at 3.4Ghz but if i shut down and reboot it doesnt Post :(
 
what temps are you seeing, what ram timmings are you using , did he use a divider ?
where as you could be having the ram fail. it has been known that 4 sticks dont clock highly together. so would try a divider or possibly check what temps you are getting, possibly up the voltage on the cpu as they can just be fickle one day oc well next time u seat it, just wont go so high. also try possibly increasing volts on ram, but not too much. good luck!

It was from me, and I used the 333mhz devider ont he ram.

Like I said to josh, the board suffers from vdroop (0.05v) when under load causing instability.
You need to up the voltage dude!
 
Ive put the voltage to 1.425 and its stable at this since yesterday, its perfect but as soon as i turn the computer totally off then on it doesnt post.

:(

I got annoyed and wacked it up and 3.6ghz because it wouldnt boot at 3.4, it started on 3.6 but wasnt stable. :p The voltage i had on the 3.6 clock was 1.46 or something aroung there and when i was on OCCT and testing it goes straight down to 1.32-1.37 its a tad strange.

P.S my Ram is fine, no problems in that department so far. Ive put it the voltage up .05v though

what do the rails on the psu look like on the occt graphs, if they are going all over the palce it may be down to the psu not being powerful enough or on its last legs.

i would also try uping the voltage if you are seeing signifcant drops unless the temps are running fairly high? but you still havent told us how hight they are going.

Just bought a new Hiper 580w in fact , that was on monday.

Anyway just started failing to post again, is it my motherboard playing up? If im lucky it posts but its annoying having to mess around with it just to start my computer up.

My Rails are fine ran OCCT and its totally stable at 3.4Ghz, Ram is 1:1 and its fine, took 2 sticks out to see if it was that but nope. Even if i put volts up it still doesnt work. Just doesnt post.

When i no its not going post the LED's on my RAM dont turn on, If this is any help.

should i RMA the board?


Temps Are At 34*C idle and 44*C load.

Check with CPUz what sort of P4 stepping it is. If it's an E0 then it should do 3.5GHz speeds easily. This machine I'm using now is at stock volts and is 100% stable running 2 threads of folding@home;

All I did was turn up the FSB (I am using Ballistix 4000 RAM) but putting on a 333MHz divider as suggested should have the same effect.

If yours is an E0 stepping P4 then I would suspect that the motherboard is the issue - that board had a huge problem (Vdroop) that needed a hardware mod to overcome. You can pick up S478 boards on auction sites for about £20 these days. The overclock above is with an MSI Neo-II 865PE that I got for £22 a few months ago.
 
Just checked its a C0. Hope thats still good though!

Im not spending anymore money of this system, ive had enough of always finding something then upgrading then finding something else. Why is it classed as a overclocking board if it cant hold VCore right , typical. Not getting a ABIT again then.

It is a good overclocking board, but it's rated as that because of all the options you can play about with. If you look at the 875 chipset ASUS board it has the same problem.

The C0 stepping is pretty good and according to Intel is good to 1.525V, so go for it!
 
Ill try and go for it if it posts. Its seeming to post more often at 3.4ghz at this point in time which os good.

I got the 875 because its the latest one i can possibly get for socket 478. Should i have gone for 865>?
