8600 overclock help

I know theres a e8600 over clocking section, but i really need help with this and dont want it to get it lost in space.

Basicly i have a e8600 the early batch (week 20 i think) and having trouble getting a stable overclock. The only way i can get it stable is leaving the volts to auto and its sets it to 1.456 v. thats for a 4ghz overclock

It idles in the high 30's and under full load its between 65-70'c accoridng to core temp. Are these temps acceptable ? They seem a bit high.

I have a p5n32 sli plus, which i had to update the bios to get the cpu working. Also have a Asus Arctic Square CPU Cooler

So can anyone help and suggest differant volts to try and what settings to change in the bios.

I'm after at least a 4ghz overclock.
 
I had my E8600 running on a P5N32-E SLi - they do require more volts than intel boards and are more sensitive to voltage adjustments. However you should be able to lower that vcore by quite a bit as that is really high.

When you say unstable do you mean Prime/Orthos unstable?

Also what memory are you using?

Go into your bios and set the memory to run "unlinked", this option will keep the memory at stock speeds and will just let you overclock your cpu.

Also make sure you manually enter the voltage for your ram into the bios as this will help. Says 2.1-2.2v on that link, but just double check what it actually says on your sticks.

Once you've done that set the vcore voltage manually to 1.3v and leave everything else on auto.

Run Prime "small FFT's" for 30mins and see if it's stable. If it fails up the vcore a notch and try again. Once you get it stable for a 30min run leave it running over night on that voltage.
 
My week 22 E8600 did 4GHZ on 1.054v on a Asus 680I.

It needs more on this Asus P45 but not sure on final voltage yet as still messing with FSB so keeping VCore little higher at stock 1.2v to make sure if it fails its due to the FSB not VCore.

Nice! What board was it exactly? I managed to get mine stable at 1.27v on my old P5N32-E SLi. All chips vary though and I think these week 20 batches liked more volts.

The Nvidia Board was an Asus Striker Extreme (680I).

This current board is an Asus Maximus II Formula (P45).

Hopefully when all is done and tested FSB wise I will be able to run 4GHZ on 1.1v at most, I don't see it doing it on as little as the Nvidia Mobo.

I did exactly what you said and just got done with prime and all seemed fine. I'll be gaming for the rest of the night so be intresting to see if i have any problems. If that all goes well i will leave prime on over night as you suggested.

The temps seemed better they was between 59-61.

Can some one also give me advice what settings to have the stuff like execute disable bit and all the other types of setting in that screen. I have the all as disabled atm. Are the any ones that are useful.

Oh and my ram was set to 800mhz i increased it to 1066 since thats the speed of my ram it says was i right to do that? My ram is actually http://www.overclockers.co.uk/showp...ady Edition Dual Channel DDR2 (OCZ2N1066SR2GK) not the link i gave before.

It was probably the ram causing the problem as the cpu was getting plenty of volts so that wouldn't of been the problem. Remember you can take that vcore voltage down still and lower the temps even more. Just take it down a notch at a time and Prime it for 30mins until it eventually fails and then up it a bit and Prime for longer.

Arrrrrh my overclock went bye bye.

Everything was going fine so i tried lowering the voltages more to get better temps but now my overclock won't show up in windows. I tried putting the volts back to the 1.3 or so it was running at before and i get the same proplem. but it shows up in the bios and boot screen as been at 4ghz

The only way to get the 4ghz back is if it put it on a.i overclock at 20% any ideas?

On a side note after the windows loading screen is done is taking ages to load my desktop (like something is loading and slowing my pc down) it never used to do that, i dont know if that has anything to do with the proplem.

hmmm i decreased the ram speed to 800 from 1066 and all seems well again but my ram on that page my ram should support 1066mhz? is there something i am missing. It seems the a.i puts the memory at 800 rather then the 1066.
 
If the bios is showing your CPU running at 4.0GHz then it is running at 4.0GHz. I had a similar problem to you when I flashed my P5N32-E to the latest version... even though speedsteep and C1E were showing disabled in the bios it would still be enabled.

Best way to check is to open up CPU-Z, then run Prime and you will see the multiplier change from x6 to x10.

That's because it's linking the memory to the cpu fsb, so it's underclocking the memory.
 
I put the ram back up to 1066 i booted up again 4ghz overclock shown in bios and boot screen. system cpu-z all show it as stock speeds and its also showing multiplayer as x10 even when prime is running.

I dont get why its not showing the overclock, as it was working fine with the ram speed before.

I'm really tempted to get a new mobo but i dont really want to with the new sockets out.

gonna try lowering ram to 1000 see if that helps.
 
What's the FSB set to though? If the FSB is 333MHz and your multiplier is at x10 then it will be running at stock speeds.

When you're looking at the memory tab (not the SPD tab) in CPU-z are the timings (reading from CAS latency downwards) read 5-5-5-15 when you try 1066?

If it does then give the memory a slight voltage bump and also the northbridge as well.
