First things first, hardware.
MB: Asus P5QL-Pro
CPU: E8200 Wolfdale
GPU: Asus EN9800GT 512MB
RAM: 4x1GB sticks of DDR2 1066 Corsair ballistix ram
PSU: Artec 550w

Now, I have been reading up on the overclocking possibilities of the cpu in question but have not been able to get even close to the 3.92Ghz that people have laid claim to.
Instead I am currently stuck at 3.4Ghz, and quite frustrated seeing as the temp doesn't get above 47C!

In short how can I get this baby to at least hit 3.6GHz?

Vcore @ 1.25
NB @ Auto
SB @ Auto
RAM @ 2.2
Timmings are 4-5-5-15
Ratio is 1:1

Also, having an Asus mobo I have found that there are more settings in there than I know what to do with. CPU AI clock twister? sounds like an icecream to me! If any1 can offer me suggestions I would be very grateful. Also, I still don't understand RAM timings too well. having all four slots full, will tightening the ram timings put too much stress on the NB? It was previously on 5-5-5-18.
Thanks

im not an overclocking expert so i may be totally off the ball. But i have managed to get a stable system.

Basically i had my system overclocked but couldnt get the RAM to work at full speed and was stuck on 800MHz or so.

So i went back to basics and set most of my BIOS settings to auto, totally against some of the overclocking guides i have read. I started with the fsb, mulitplier and vcore volts inputted by myself.

as soon as i got the vcore volts low enough (and stable) i then manually input the NB voltage until again i got it stable, then SB volts and now im going to sort the RAM timings and volts.

This worked for me, i just went with the concept that i would let me PC worry about everything while i changed the cpu speed, then slowly took over the BIOS myself by manually inputting values.

i might be stating the obvious but its just my experience.
 
I had the same kinda issue when i first tried to overclock my E8400 on my P35 mobo, just simply did'nt want to overclock.

And i was like what the hell, i know what im doing kinda lol, but after taking a break, and rethinking, i noticed that i forgot to set Vtt, and it was left on auto, and for some reason probably was setting itself to low or way to high.

So i set that originally to 1.4 to see if it was the problem, it was, once i set that manually off i went, i now have it at 1.2/1.3 depending on my current overclock.

Id suggest setting vcore manually, vtt manually, Nb and Sb manually, and you can leave memory on auto so that it will work at closer to higer speeds.

Vcore for now 1.25v
Vtt 1.2-1.4
NB 1.2-1.4 (depending on how high ur going on FSB)
SB dos'nt need a lot, so just manually put it to its lowest setting
Memory stuff leave on auto for now untill cpu is sorted.

Test with that, and raise vcore if needed for newer higher clocks, you really should'nt need high vtt or nb unless ur going really high on the FSB.

The timings won't really stess the NB, more the memory itself, but if within spec ur fine.
 
Ok I have an Asus P5QL and I believe it is labeled as FSB voltage termination on this as i don't see a Vtt anywhere. but it states that on auto on detection of a wolfdale cpu it reduces FSB vt to 1.1 :o I have active voltages of around 1.18 up to 1.21 so im not entirely sure what it terminates ??? Anyway, can't find Vtt and FSB voltage termination isn't working either. Still at 425x8. I dnt even need this chip any higher, its just annoying me that it won't!!! even though it is perfectly healthy! Its like a kid having a tantrum! Suborn such n such!
 
Could my FSB strap have anything to do with this? Currently set to auto as im still confused as to what I should set it to. Im pretty sure it needs to be set to 1600 or 1333 but don't wanna make my latency plummet! Im looking pretty stary eyed at the explinations for most of my bios settings.... Think i need some1 to explain it with finger puppets :P
 
Im not really to sure, as iv never used that mobo, so might best if some others that have reply.

I'll have a read up on your mobo's bios, and see if i can figure out what needs changing and what not, but hopefully someone with more knowledge of ur mobo will post before i can.
 
Thanks man, I've been reading up on it also by typing in the terms separately but FSB northbridge strap confused the hell out of me! Apparently you have latency settings on your northbridge that are not available to the end user but are set in grades by Asus. To calculate your grade it takes your (current max multiplier x Old multiplier) x current bus rate for CPU. So for me that would be (8*8) x 425 = 425 (simple :P) and i have a dual core so its x2 for my cores. 850MHz? I think thats right. So, because I have a dual core my Northbridge can have tighter latencies but has a lower overall FSB? I think its time for the finger puppets...
 
It's your motherboard mate, p43 chipset has trouble reaching high fsb well in my experience anyway. I've got a system here with the exact same motherboard and max out at 420fsb on an e8400 which I know does at least 4ghz on low volts from another pc.

You could try upping the fsb by a fair amount incase your motherboard has a fsb wall, but I think possibly you've hit your max fsb. Only thing you could try is a chip with a high multiplier.
 
Yeah i figured it was the board from the start it does say it has a max FSB of 1600, but i thought it would be able to handle more. being the 'pro' model. Pff! P5QE or P5N nxt time or just go to Giggabyte again although I have had 3 GB boards and all have blown capacitors, 2 of which weren't even OC'd! What boards have you guys decided to go with? P.s. im lookin mid range not Strikers n ****. £120 max
