Hi N7 thanks for your contributions thus far - No I have not memtested is there any windows memory tool I can use ?

Exactly what i told you.
Massive vdrop & vdroop.
You are getting more than 0.08v lower than what you are setting in the bios, just like i was.
And you'll need at least 1.35v under load to get anywhere with that chip.
That means at least 1.425v in the bios, just as i said in that earlier post.
In short, you need a lot more vcore before you're going to get anywhere close to 3.4 GHz.
Try 1.425v as long as temps are reasonable...that should get you closer, though you'll likely need more for 3.4 GHz.

Eh, things are going to get very cozy toward your OCing goal.
But as long as warm temps don't scare you...
HCI Memtest
http://hcidesign.com/memtest/
Stresses RAM & NB bigtime; you must set each instance to use up a total of almost all your RAM. Try 4 instances.
For initial basic testing, Memtest86+: http://www.memtest.org/
And don't use Orthos.
Use P95 25.6. Small FFTs for CPU; Blend for CPU + RAM; Large for everything.
Or get IntelBurnTest aka LinPack: http://www.xtremesystems.org/f...howthread.php?t=197835
But be warned, LinPack absolutely rapes systems & make P95 look like a joke.

Was that screen shot with the voltage from the CPUZ shot? If so I think you may run into temp issues. Take a look at Xigamatek S1283 at neweggg. It is $27AR and will much better than the Zalman you have now. But we are making progress. From the looks of things the hardware you have should do 3.4 without issue.
N7 how this looking?
I set it to 1.35 In bios
will let this run and see where I end up.

25.6
Not 24.14, which doesn't support quads unless you run 4 instances.
Get 64-bit one if you have x64 OS.

You're getting the idea now; just remember what you set in the bios is pretty much 0.08 to 0.1v lower than actual vcore under load.
So to get to "max stock vcore - 1.35v" for your chip, it looks like you'll be needing 1.45v in the bios, & temps will be very warm when you do that.

He has a P5B-Plus...same thing as my P5B-D...that's why i am pretty much foretelling everything he's going thru...i've already spent days & days fighting with mine back when it was my main mobo; nothing new here i haven't seen before
It's an ugly beast for clocking quads, but if you aren't scared of high idle temps due to huge droop, it can clock them still.

That screenie show one core being stressed.
I'd get more excited when he gets & runs the proper P95 version stressing all four cores.

Im 18 minutes into the torture test with the 4 threads on Prime 95 - all cores `100% and temps are at 59 which isnt not too bad. Maybe I will stick with 3Ghz and not risk anything more, thats like an 800 Mhz overclock which these days of the 8600 hitting 4.6 , not amazing but it's still decent..
The extra 400 Mhz wont save me from upgrading in a year anyhow, so its fine.
Thanks for your work N7, I didn't catch how much the Vdroop was from my bios to windows ! I thought my vcore was low.

You got the right P95 i take it?
You will find temps get pretty warm as you increase vcore, but if you can get 3 GHz stable @ 1.25v, that's really good actually.
Based on your current results & VID, i suspect you could actually do at least 3.5 GHz from that chip, though you'd need a better cooler.
I'd see how far you can get up to 70-75c load temps.
With around 1.3v to 1.35v load (1.4v to 1.45v bios), you'll likely get those sorta temps & probably will do at least 3.2ish to 3.4ish GHz.
Just guessing, but that chip easily has 3.4 GHz in it.
Just needs more voltage, & at a certain point, you'd need better cooling, though it's definitely fine now.

I will run this for 2 hours and see

Don't mind Aigo, he's quick to blame everything on Abit/MSI.
yeah good, after 3 hours I had no errors.
I just need to get a quite cooler, I have set up a thread for one in the cooling forum.
I have a budget of £50 to spend on a cooler from www.overclockers.co.uk

clarkey
the P5B is easy to fix on your vdroop issue.
Just dont push high voltages when you do the pencil mod and it will fix your vdroop issue.
Im sorry, usually boards with that bad of a vdroop on quads is the ABIT and MSI series, so i automatically assumed you had one of those.
