quite happy with my 3870 :) 
not sure if im going to flash the bios and go for the 1ghz core that alot of people are getting though.

System booted up fine today at 2.88ghz (1650 qfsb). Went on the Asus forums as suggested and they talk about a FSB hole typically between 375-405 which would explain why it refused to run at 1600. Think I'll leave it as-is now, happy with a 1.02ghz o/c.

1.02Ghz is certainly nothing to be sneezed at, but I managed 1.2Ghz with the P5N-E SLI, let alone the board I've got now, so something tells me you can probably get more out of it. Just takes patience I suppose...

@maccerm
looking back thru your posts heres what i would try;
firstly get everest or pcprobe to see what your voltages are doing on auto, then you know where to continue from. then set your ram to unlinked, set it at stock timings and volts for now and leave it, your mobo will change the speeds of it to work with the dividers its has and it will take it out of the equation for now. you can always play with your ram once you know where you cpu limits are, and trust me this will take some time and patience. once you have done that you should be able to keep uping the cpu. also try bios 803 as from what i have read it is the best one for overclocking, not sure about cpu support tho, should work, dam my mobo doesnt even offically support my cpu so...

Thanks guys. I?m pretty sure I?m not near the limit of my cpu yet, after all I?m only at 1.42v and that?s perfectly stable. I?m just concerned about the temperatures. I think as you say I should get Pc Probe or Everest etc on there ? I?ll do this tonight. With Speedfan I get the core temps for my cpu, which seem to be about right, but I get a lot of nonsense readings like ?Temp 3: 102c? ?Temp 1: -50c? ? I can?t identify the 3rd cpu sensor reading so I?ve no idea whether I?m staying safely within the 60.1c thermal spec of the cpu. On the voltage side it reckons my vcore is 1.33 when I?ve set it manually!
When I run Orthos torture tester my Core 0 & 1 temps hit 55c ? is this safe and does anyone know what that would translate to roughly as the overall temp of the cpu taken from the 3rd sensor?

if you can get the new speedfan beta it is spot on for your core temps but the older one isnt, everest says the same as coretemp which is ment to be the best for cpu readings so...
if your concerned about running too hot get somthing like throttle watch 2 (there are others too) to see if your cpu is holding itself back when it gets warm, if it is throttling it means your pushing it too far, if not carry on :D

I'm at 1.39V on my E4300 and made 3.15Ghz. At 1.42V, you should be able to push slightly further. Have you considered upping your chipset voltage?

Well until I get another monitoring programme on there I'm not certain of the stock chipset voltage, and I'm not sure if the m/b controls it dynamically anyway when set to 'Auto'. On the Asus forum there was a thread about cold start probs and someone on there said to set the n/b voltage to 1.35v. I'll get some new monitoring stuff this evening and try and work out exactly what everything is set to.
As you say tho I should be able to get higher than 2.88 at the current vcore. It booted at 2.88 at 1.418v and ran 3dmark fine but froze on Orthos. Perhaps 2.95-3.0 ish at my current vcore of 1.425v - Upping the n/b may well let me get higher, perhaps even lower the vcore down again. I'll let you know how I get on later. Oh and Sam, I have asked about a thousand times! But just to pin you down on this, you think up to 80c on the cores is safe?

Using CoreTemp specifically, I pulled temps of up to 81C on my cores, with no ill effects. I can't say what speedfan/Everest values to look for, because I never used them back when I ever had temperatures that high. Using Speedfan though, anything up to c.51/52C for the CPU itself should be fine.
As for the NB voltage, all I know is that at beyond 2.67Ghz 'Auto' wouldn't boot, 1.5V would.

cores are about 10/12c above what speedfan reports for your cpu. everest is spot on for my setup. you should have no trouble hitting 3ghz on 1.4v it must be ram or chipset (maybe cpu vtt) that is stopping you but my money is still on ram.
edit
my chipset only needed 1.2v to do 1333 fsb and only needs 1.4v to hit 1500 but i think i was lucky with my board.

I've just run coretemp and the cores are 33c - identical to the idle temps that Speedfan is reporting. (I don't have an intelligible CPU readout tho!) Coretemp states my tjmax is 85c, so at 55c full orthos load I can assume I have a little thermal headroom then? Enough to get me to the 3ghz mark. I haven't tried to go higher than 2.88 yet, so I haven't come across a limiting factor yet - I think it was just having a funny five when it wouldn't boot the other day, it has been fine since. Just got my chipset fan thru so I'm gonna fit that then see what it'll do!!

"having a funny five" is how I'd explain the behaviour of my P5N-E SLI pretty much exactly. Inexplicable changes in performance, whether it will boot or not and so on. Reliability wasn't that board's strong point!

Sorry to barge in here like this guys! But I have come across a slight problem... According to this 3DMark06 run: http://service.futuremark.com/compare?3dm06=4184277
He got 5835 Marks for the CPU at 3.9Ghz, and with mine at 4.05Ghz, I got 5547. Shouldn't I be getting more than him??? I have the ram at 2.2v (stock) at 5-5-5-15 from the stock 4-4-4-12 and I believe it is a 901Mhz, and the CPU at 1.6v. The high voltage on the CPU is only for benching, so don't freak out!
Is there anything else I should be changing? I think I should be upping the NB voltage a bit as I cannot run 3DMark06 with anything below 1.6v on the CPU. I get a error, but maybe that's a Vista problem? I try to run it in XP (duel boot) but it stays idle at the loading screen and the process usage for it is always at 25.
Any ideas as to getting a better score, bringing down the voltage and fixing 3DMark06 in XP?
Sorry for the long post guys!!

Waymon3x6,
Do you have any Sandra 2007 benchmark scores? They would help in pinpointing the problems. could you post Screen Shots of the CPU Arithmetic and Memory Bandwidth benchmarks. That would give us an idea of what's going on inside your computer!

Russ

No, I dont have any sandra benches, but I will do that stuff when I get home I guess, at school right now. :(
Russ, do you want me to run the bench at 4Ghz or stock?

kill all the system processes that arent necessary gives a boost on 3dmark 06 as with alot of benchmark programs, dissable your virus checker ect and background services, bench straight after booting ect. as long as your system is useable and games play ok in the real world you shouldnt worry :o)

The set up you used when you ran 3DMark to run your tests would be the most meaningful!

I wouldn't really recommend doing that unless you are not connected to the Internet, as your system could be vulnerable to any virus!

Got it running at 2.95, 1685 qfsb, with no changes apart from unlinked mode. Now tho my memory is running at 789 vs the 825 it was at 2.88 linked. Got an extra 68 3dmarks now 11650, which I think would be better if I had the ram back up to speed. To get the mem up to 800 I need to run 1707 qfsb which is 2.988ghz. Before that I tried 3.0 which is 1715 qfsb that with the normal memory timings and it booted windows, tried 3dmark and got a blue screen error half way through the first test which would suggest a memory error. Tried setting the n/b to 1.35v as in the asus forum but I had to jumper CMOS reset after that! Does something memory wise need upping? Do you reckon it's worth giving the cpu another notch just to see? I'll try and see if I can find my current n/b voltage.

Yes, but the question is which memory? Video or system! 3DMark 06 killed my video drivers one time and I got a blue screen message telling me that my video drivers had stopped working! LOL!! This was on an Asus MB and my D-940! I had to un-install the video drivers and re-install them again.

usually the memory bandwidth will be highest with the memory running at or as close as possible to it's rated speed and at rated timings or tighter. in other words usually it's better to run the memory at it's rated speed (or as close as possible) and rated timings as oppossed to overclocking the memory and loosening the timings.

I've never had a problem with 3dmark... ever. Sounds like if you had a problem after running it the drivers may have been dodgy to start with, and 3dmark pushed them over the edge!

Russ, maybe you weren't running 3Dmark approved drivers? I remember you like to stick to the older Forceware drivers.
