Just flashed to F4 and temps spiked on idle like 6C. CPU-Z was showing 1.4 instead of 1.3. I also found it would happen with the RAM too. It spiked to 2.1 and there's no way of setting 1.8 AFAIK, so it's at 1.9. The only one I didn't move was the PCIe, but now I'm wondering if that's getting overvolted too!?!? Anyway to check that guys?
GOT another E6400 arriving tomorow , week 27 , anyone know if they are good???
didnt saw yet any result of E6400 week 27

Is this power supply enough or :nono:
are you saying you've overclocked your CPU to 4.2GHz on air because i don't believe it for a second unless you can provide some screenshotsQuote:

belive or not i dont care, 4200 is not stable.. 4000 for some test with big room fan on the side of the box yes. But is running 25/7 at 3,6 :toast:
And my quastion was is the power supply enought?
can't you take a joke champQuote:

that PSU i've never heard of and would definately replace it with something beefy man..............~500+W Tagan will do
Sirtec is good PSU here in Bulgaria, exactly like Fortron, Chiftech
Is not bad, no overvolting. I read for it, he is real 400W power. Is this enough? (sorry for english, i'm not listening my teacher :nono: )
in 4ghz I only run superpi 1M - 11sec
Now the room cooler is not here with me to run that high. And i'm just a gamer, not 3dmarc tester :nono: (I like that emoticon)
So.. 400 rea watts is enought?
ok i definately don't believe you did 11second 1M time with a 4GHz Allendale lol
well if your system is stable don't worry about changing the PSU i guess

I am priming right now at 1.5875v on my E6400 at 3.4Ghz (486X7) and the temps are bouncing around from 71-77C but I was under the impression that these readings are off by 8-10C? Is this true?

idiotec, what are your temps?
General question: With temps getting very high because of 1.575v does the CPU slow down because of the heat?

Maks FSB with this board is 450Mhz with V fsb at 1.4V and VNB 1.6V. Bios is 0507.
The CPU is a E6400 L626A283
It is not stable at all, Was one step away from finnishing 32M.
It works fine with 1.3125V (BIOS) at 3.2GHz. Even if I raise voltage to 1.55V it doesn't help too much.Quote:

Highest spi stable so far

How many of these overclocks at 3.4,3.5,3.6Ghz are 24 hour stable on Orthos?
I can get to 3.5Ghz on my 6400, but its only 4 hour stable on Orthos, but every else seems perfectly stable on what I do? I can do single 32MB SuperPi also, but not dual. Is there any special assigning of cores to each SuperPi instance?
To tell you the truth, as long as my system is stable for what I need it for, why bother. Sure you can say my system isn't truely stable (I am not saying it won't pass the 24 hours Orthos, I just don't know, never ran it). But I fold 24/7 on both cores and have never had an issue. That is stable as far as I am concerned. Anything more is just unecessary.Quote:

But I am contemplating whether to put it back to 3.5GHz and just run it there.

What voltages are you using (gMCH, FSB , memory & timings/ratio etc)?
I have it at 3.2 now, seems to need around 1.4 to keep it stable though
Just like you said, run your computer at whatever speed meets your daily needs. Orthos/prime is just an easy and standarized way of comparing the stability of your system to that of anothers.Quote:

Hmm, damn DS3 is giving me problems.
I flashed to F5, but for some reason it didnt seem to work. Still showing F3 in everything.
Also, even though it will run for hours, benchmark etc. I restarted it, and now black screen. Time to reset CMOS again, which means removing the damn video card because the CMOS reset is in such an awkward position.....
BTW, I dont know if this has already been answered, but when changing the ddr voltage on the DS3, does it add whatever amount (i.e. +0.4) to 1.8volts?
So if I put +0.2, my ram should be at 2.0volts?
Absolutely safe.Quote:

Copy of my post from another thread:
I'm making progress. Best thing was the cooling on the NB
http://i13.photobucket.com/albums/a2...nchmarks/3.jpg
One thing I have noted though. The NB heatsink is totally inadequate. I tied a 60mm fan on it, and it now stays cold to the touch, and I've had no re-boots or stability problems since. (I had to 'ghetto' the lead into a 4 pin molex though, have it @12v, gonna change it to 5v should be plenty to keep it cool)

I prefer run Orthos using Blend test (CPU & RAM) or Small FFts ( stress CPU) cause large FFTs test just stress RAM .
regards
Large FFT's doesnt just stress ram, it stresses the CPU also. Its just with the size of the FFT's, it cannot all fit in cache, so system ram is also used extensively.
Small FFT's do ONLY stress CPU.
i believe large fft is more accurate then blend test.. last time during my AMD rig, blend test nvr gave error, but one day i tried large fft, it failed right after 10mins..
Indicating you had a ram problem.Quote:

Either my P5B or my XMS 5400C4 keeps me from running any higher FSB, so I dont know how far it will go.
With 3.3 @ 1.32v ... 3.5-3.6 on 1.4-1.45v maybe?
so decide - 3.2 or 3.3 GHz. But in both cases my answer is YES!Quote:

Lapping
I’ve finally got my E6400 running at a reasonable temperature. Using Orthos/dual Prime it had been reaching 70 deg C (T Junction) even at 400 MHz FSB, so I decided to take another look at the heat spreader. As you can see in Photo 1 it was clearly raised at the edges. See also that it has scratched the base of the heat sink where it was clamping at the edges only.

After a bit of wet and dry at 360, 600, 800 and 1200 grit I reached a point where the centre of the IHS was bared to copper so the heat sink would make close contact directly above the core. I didn’t want to keep sanding until all the nickel was gone without testing the effect of this first.
With everything reassembled and dual instances of Prime running for over two hours (400 FSB) I now had a CPU temperature of 62 deg C, a benefit of 8 degrees C! – and that’s before the 200 hour bed in of the AS5 thermal grease. (Ambient was 23.5). I didn’t believe it before, but you have to try it if you think your temperatures are limiting you.

I’ve done some benchmarking with Driver Heaven Photoshop Benchmark v2 and SiSoft Sandra 2007 to test out this issue of the chipset strap setting. It can be clearly seen that 400 FSB is superior to 401 FSB and almost as fast in day to day tasks as using 425 FSB. However there is the option of setting BIOS to 400 for booting and then using ClockGen to raise the FSB to 425 from within Windows at start-up. This option produces superior benchmarks but requires a substantial FSB and NB voltage boost. See table below.
FSB--------------------------Driver Heaven--—SiSoft Sandra Mem BW
Boot 400 FSB------------------105.0 s------------7272 MB/s
Boot 401 FSB------------------116.0 s------------6700 MB/s
Boot 425 FSB------------------101.1 s------------7200 MB/s
Boot 400 ClockGen 425 ------98.5 s-------------7318 MB/s
Based on the results here it is apparent that this board produces great results at 400 FSB with minimal voltage increases over default required. The voltages required at each of these settings are as follows:
FSB---------------------------CPU V BIOS--Mem V--FSB Term V--NB V
Boot 400 FSB------------------1.3875------1.90--------Auto-------Auto
Boot 401 FSB------------------Ditto
Boot 425 FSB------------------1.5125------2.00-------1.400------1.45
Boot 400 ClockGen 425 ------1.5125------2.15-------1.450------1.55
Actual CPU Vload is 0.06V less than BIOS setting in all cases.
The maximum clock at all the pink (one less than red) voltages in BIOS (CPU 1.55V, FSB 1.4V, NB 1.45V)? That’s 450MHz FSB or 3.6 GHz, but it needs all fans running at maximum which I don’t want, and it fails Orhtos after a time. 438 FSB / 3.5 GHz is rock solid (see Photo 2), but requires too much voltage and fan noise

Orthos (dual Prime) and ClockGen
I did have a suspicion that using ClockGen would allow some to cheat the benchmarkings. However, Orhtos reports the boot FSB frequency even after a change is made to the FSB with the PLL of ClockGen. Ha, so you can’t cheat on Orthos.
Memory Settings
Using MemSet 3.0 is the easiest method of optimising your memory timings. From within Windows you can change most timings and apply them without rebooting. Obviously changing some settings will freeze the session. Once you have tested the settings you can either get MemSet to apply the settings for each session, or you can just apply the settings in BIOS. You can see the settings I ran with in the screen shot.
Other BIOS Settings
I’ve found that leaving CIE enabled does little to harm performance. This setting enables the Intel Speed Step function which allows the CPU to reduce from an 8x multiplier to a 6x multiplier when idling. Normally Speed Step would also reduce the CPU voltage, but this is disabled when using other than Auto in the BIOS for CPU voltage. As a result I’m not sure whether the savings are as great, but at least the CPU clock speed is reduced when the PC is sitting idling.
Quiet Computer
The best speed to run for quiet computing is 400 MHz FSB or 3.2 GHz CPU clock. Front and rear fans are at 1000 rpm, CPU fan is at 1700 rpm, GPU fan (Zalman) is inaudible on 5V. The two hard drives are in Scythe Quiet Drive enclosures and supported on foam rubber feet.
