Howdy,

I'm pulling my hair out now as I just do not know what you guys are doing to get the Asus P5N-E 650i with a E6600 to 3.5ghz and higher?

Im desperately trying to get 3.5ghz (thats all I ask) out of it, but I currently have my vcore to 1.525 at the moment and although orthos is at 1hrs 15mins it will go into "STOPPED" mode any minute now, as 1.5125 died at about 1hr 10mins. Im getting 56c during orthos, so the temps are okish.

That is the MAX vcore I am prepared to go to... and tbh Im not happy with that, so if it dies again im going back down to 3.4ghz and see what I can get there.

Can some of you with these boards and the e6600 tell me what you are doing to get 3.6ghz at 1.475v vcore? That would be impossible for my setup?

I want to change the 1.2HT and the VTT but I do not have the option to do this? the only voltages I can change at Vcore, DDR, Northbridge and Vcore offset (whatever that is?)?

My rig is:

ASUS P5N-E Sli
C2D E6600 w\ Artice Freezer Pro 7
GeIL 2GB (2x1GB) PC6400C4 800mhz DDR2 RAM
Corsair HX 620w PSU
Antec Nine Hundred Case w\ 1 extra 120mm fan
BFG 8800 GTX OC

Can anyone help me with my setting in the mobo, as that is what the prob is I am sure, as my temps are fine! So it has to be sumin in the bios right?

I dont fully undrstand the jumperfree clock config page? My old RAM divider use to be down as 400mhz 333mhz etc, now all I have is Auto 1:1 5:4 3:2?

Im setting my Memory clock mode to unlinked and puttiing my Mem DDR to 700 and my timings to 5-5-5-20 2T to make sure its not the ram screwing things up... that right... right?

Anyone help!
 
Hi mate,

Well i have that mobo and that CPU and admittedly I am on water but I am have it at [email protected] and thats 12hrs orthos stable with temps around 48c so think you should be able to get that, although each cpu is different.

Here are my settings:

Vcore = 1.35 +100mv (don't have the offset volts to auto)
Mem Volts = 2.259
NB Volts = 1.563
FSB = 1600
Memory DDR = 800 Unlinked
Memory timings = 4,4,4,12

Under CPU configuration the only thing i have enabled is Execute Disable Bit. Under Chipset I have disabled all the Spread Spectrum Control. Under the Onboard Device Configuration I have enabled the following:

Onboard Nvidia LAN
Onboard 1394

I have left the last 4 things on that list to what the defualt is showing.

Hope that helps.
 
Cheers AFK Ill giive them setting ago in mine. Orthos is still running after 1hr 50mins on 1.52v so i am gonna leave it like that for at least 3 hours... then i will try your settings and see how long that last for?

Question, what is the point in the 1:1 5:4 and 3:2 ratios? When you can set it to unlinked and change it yourself? I really cannot see the point in those options? When I set mine to any of those ratios my ram jumps to 1000mhz+ and thats too much, so I couldnt use those if I wanted... does it matter?

Do you reckon 3.5ghz on 1.525v is ok? As I say the temps are still at 56c and havent moved an inch... im fine with those temps, just worried about pumping 1.525v's into my CPU 24/7 scares me a little!

I'll let you know how it goes!
 
Your CPU may not be capable of 3.6GHz.

I have an E6400 that will do just over 3.7GHz. I have another E6400 that will do 3.4GHz in the same board and not one bit more.

If it's an L627B/L628B/L29B then yes, it should do 3.6GHz+, but other than that, there are no guarantees.
 
How do I find out if it is a L627B/L628B/L29B

Also, to answer my prev question, do you think it is oking running my E6600 at 1.525v? The temps on load are 56c.. although its at 57c now, but it changes between each?

You posted this elsewhere and it's utterly straightforward

The DDR2 RAM clock runs at twice the CPU FSB speed

The Northbridge runs at 4x the CPU speed, so 1:1 runs *** RAM at the same speed as the Northbridge. 3:2 runs it at 2/3rds (66%) the speed of the Northbridge and 5:4 runs it at 4/5ths(80%) the speed of the Northbridge.

It seems quite straightforward and it allows you to run really fast RAM if you have it available. Running in Linked mode is slightly faster than Unlinked (about 1-2%).

Why not put everything on AUTO until you've sorted out the CPU?

Oh - and you might have missed it, but AFK_Matrix is running a water-cooled Northbridge. Is your Northbridge cooling OK?

On the side of the CPU box it'll say something like FPO/BATCH# L628B459

The bit after L6 says when and where it was made. The best steppings are reputed to be L627B/L28B/L629B and pretty much anything with that code on E6300-E6700 will all do 3.8GHz, if the rumours are to be believed. My own one is an L628B E6400 and it does 3.7GHz, whereas my L628A only does 3.4GHz so I think there is some truth to it, even based on a tiny sample of 1.

Thank you, that makes much more sense now... didn't fully get it before?

I've not got it on auto cos I thought that my mobo would then put the settings to high and it might start killing my overclock, then i would think its the cpu but it is actually the ram. So I put them to lower setting than their stock to be on the safe side!

Still dont know if you think 3.5ghz (1556x9) @ 1.525v is safe? Orthos is 2hrs 40mins in now and its still going.. so better than before, but still worried about that vcore... although many people say the max vcore you should set on this cpu is 1.55... that I will not go to!

Saw the watercooled bit, but didn't reaise it was on the NB too. My NB is bare on this board, although I do have a Zalman ZM-NB47J Northbridge Cooler knocking around... but I dont think my mobo has holes around the chip for this to go on?

Ok got my box here and it says:

FPO: 7639A204
Version: D63625-002
Pack Date: 02/07/07

But more worringly, its says 1.35v MAX, Im at 1.525v... do they just say this for precaution?

Ok I tried similar settings to this, but I went for 3.5ghz, not bothered bout 3.6ghz for now, I just wanna get 3.5ghz.

This made orthos "STOPPED" in about 5 minutes?

So the fact that you can get a 3.6ghz clock on the same vcore voltage that I am for a 3.5ghz must mean my E6600 wont clock any higher, cos we have the same boards and processors and its nothing to do with temps cos my temps wont exceed 52c on that voltage?

I'm too confused now and although 3.5ghz run for 3hrs on orthos without fail, I was at 1.525v and I don't like that. So I have gone to 3.4ghz.

Dunno why I have so many probs clocking, everyone else seems to get good clocks on their processors and I can't... the same happened for my last AMD X2 4400+ clock, I couldnt get nearly as high as others... I'm jinxed me thinks :)

Thanks anyway gents, I appreciate your help... but I think to get 3.5ghz I would need someone here to help me do it, cos I just cant do it... and dont understand most things!

When I get an hour or two into my 3.4ghz clock I will post screenies of my clock, and you can see it and maybe see any dodgy settings in there... and hopefully make me feel better about a 3.4ghz clock compared to every other E6600 owner on the planet that can easily get 3.6 out of theirs :)

OK - It's a week 39A which I think is the subject of a thread saying "don't buy these, they're pants" so you've probably done quite well on this particular CPU, I suspect.

No, it will run 24/7 @ 2.4GHz at 1.35V. That's what it's rated at. Overclocking voids your warranty and you do it at your own risk. That's the first thing the stickies say. If you can't afford to blow the CPU up, stop overclocking right now. You're looking at a 50% overclock. That's extreme on air cooling. You can probably do 3GHz on that CPU at 1.35V, and if you're worried, then take it back to something closer to stock, it'll still be very fast.

AFK_Matrix has water cooling and her CPU may be a better clocker than yours. She was pencil-modded her motherboard and basically has this down to a fine art.

She's a lady and I'm no gentleman ;)

No they can't. The average overclock on an E6600 is about 3.2GHz. Check it out. The ones doing 3.6-3.8GHz make a lot more noise about it, yes, but the average is well under 3.6GHz. 3.4GHz stable is a great overclock and don't let anyone tell you otherwise.
 
Apologies to AFK... didnt realise you were a laydee, so my last statement is thanks ladies and lads :)

Ok typical I get the dud CPU, but oh well not the end of the world. I did actually see these posts, but you have no power to control what batch you get from ocuk do you? At least I knw anyway!

I'm now 1hr 56mins into the Orthos test at 3.4ghz (1511x9) on 1.475v and it seems ok so far.

The temp has risen to more than 52c so far, so its pretty good I suppose, and aslong as orthos runs for a while longer I would be happy with it at this.

Although my BIOS says 1.475v, PC Probe doesn't go above 1.42v, so not sure what to believe? CPU-z says 1.408v to 1.424, so its running lower than what my BIOS says.

Gonna leave it for at least 3 hours then i'll whack a screenie up to see what you think with all the stats!

Thanks!
 
stick with that overclock- 3400mhz with less than 1.5 Vcore to stay safe
and this is more than enough for everithing you want to do with your pc :)

right now I´m using mine at 2667mhz( 333x8) with 1.34 Vcore and tight Ram timmings 12-3-3-3,TT 120 fan at minimum (no noise) and CPU Temp at 30ºC in TAT :)

and the pc is fast,real fast for everiday use :)

Could vdroop be causing this problem? If so then there is a relatively easy pencil mod to fix it. You can search the "official" thread for this board or do a quick google.

I doubt it as the Vdroop usually manifests itself as normal operation at light loads, then the PC crashes under load. To compensate for this you just put the base voltage up which makes the system idle hot, but it's stable at load.

When you do the pencil mod you can bring back the basic voltage so the system idles cooler, but remains stable under load.
 
Thanks, But I am gonna stick with 3.4ghz as I dont want to get in the 1.5v+ for my overclock... that worries me to much.

I have posted my overclock at: http://forums.overclockers.co.uk/showthread.php?t=17714689 so if you could have a look at that and give you opinions I would appreciate it!

Unless you see anything wrong with it, and see a way of me getting to 3.5ghz without exceeding 1.5v vcore, I am gonna stick with this I think... its better than the stock 2.4ghz I suppose :)

And seeing I have the "dodgy" batch, I am quite happy with th eclock I have... I was really annoyed earlier, seeing I was seeing clocks of 3.6ghz (and 3.9ghz in sime places) and I couldn't reach there... but now I know I have one of those batch I am happy with 3.4ghz!

Thanks for your help!

can you still get these chips or was that awhile back? if so how long we talking?
 
They have pack dates from last August. It's pretty much accepted that the true Conroes are the better CPU's to have and that the newer E6300 and E6400 Allendales run hotter than the older CPU's.

Basically, if you are buying second-hand, older pretty much equals better.
