I've just received my DS3 and a week 28 E6400.

Anyone got any results for a week 28 E6400?

Seem to have trouble keeping it stable at 3.4, 3d mark keeps hanging.

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

That is stable as far as I am concerned. Anything more is just unecessary.

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.

That's why bother I guess... :)

i'm surprised that E6300 retail CPUs seem to overclock better with lower vcore than E6400 what's the deal there

any week 30+ CPUs around here

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?

On one hand it is nice that the board will automatically set the voltage to stabalize your OC however on the other hand this is not very accurate and every time you boot your PC it will fluctuate a bit. NEVER USE AUTO. I garauntee those people claiming to OC at default vcore will not even post if they set the VCORE from "normal" to manual 1.325.

I do not think so.My system would boot with NORMAL at BIOS.After I have selecte 1,475v,it actualy boots immediately and is completely stable:woot:

74C right? That seems awfully high...does it throttle?

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)

4GHz unfortunately was a no-go :(
have'nt tried over 1,6V and probably wont try. maybe ill try with a different bios later.

No, it doesn't throttle, and I've pretty much accepted that Coretemp is just plain wrong.

Looks like F5 for the DS3 has helped a bit. It didn't really help overall OC, but did get 470FSB from BIOS :)

Coretemp...ah, that explains it. Wait, it ways 74C in the Asus thing...that's off too I take it? I guess it really only helps to compare temps with folks using same board/bios, eh?

What kind of temps in Orthos @ 4+ hours?

didnt try, just runned it for spi. im sure the temps wouldnt have been nice. i need new cooling because the freezer cant seem to get its job done. it gets reallly warm

Yeah, I've got a Ninja sitting here waiting to be lapped. But I don't have the padding anymore. I tried using the padding on the bottom of a mobo box, but that sunk over time and then the bolts came loose slightly. I noticed temps rising gradually and finally put 2 and 2 together. So I wonder if Scythe could send me a pad for some $$. That or I'm gonna cave and Tuniq it up. :D

Not even then. Some people are reporting lower temps, but I've tried everything short of actually lapping my E6400 and still get the same temps. Stock cooler, an Xp90, or an Ultra-120 all read 70~ when running Orthos. I've reapplied, readjusted, prayed, and everything else I could think of. At one point you just either accept that Coretemp is wrong, or your IHS is screwed. I went with Coretemp being wrong :p

It's not like my heatsink doesn't get warm; it does heat up pretty well.
