Any chance you can run the mod SPI? I have a feeling you're losing like .1 sec but may gain some OCability (YMMV though, I can't boot at anything other than 7.5ns at 3.15GHz and above).

Nice, where did you get the 146?Quote:

peace perc,
Yes, it is!Quote:

Edit: Just pulled it and it was a perfect seal. Back on schedule now. :)
Interesting good or interesting bad???Quote:

Of course this might be because my memory crapped out a week ago - I can't really know what's up until my G.Skill's come on Friday.
What do you think? Should I push it up? How high?
Got my 148 from ewiz on Tuesday. I was going to post some screen shots today but more pressing issues came up. Hopefully tomorrow as I'm at work again.
Anyway, it was the CABNE 0528 gpmw that seems to be comon for the 148s.
Initial OC results with DFI ultra-D and air cooling at 15C.
*3000Mhz is superPi 1Mb stable at 1.456Vcore.
*3100Mhz is 3DMark stable with 1.55, semi-stable with 1.525...but for some reason will not complete superpi 1mb at 3100Mhz even with 1.6 volts. Played with mem settings in A64 tweaker, mem voltage(TCCD), speed, etc....no go.
If you think you're memory isn't working quite right maybe you could go down to a single stick or drop a big divider on it to push it low enough it doesn't get in the way of your OC. If you do that and Prime comes up okay, push it up a little more if you're temps are okay.Quote:

well man i would have to say that at 1.55v in the bios doesnt help my stableness at all when at 3100mhz it will run for long periods of times then out of the blue the system will freeze:shrug: plus the heat at that voltage is just as hot or hotter then my x2 chip was!! these things put off heat big time when getting in the 1.5v and up.... i backed it off to 2900mhz at 1.4v to do some more burn in ill try the higher voltages and ocs later to see if it helps any.. ill post more later..Quote:

I've noticed these things dump less and less heat if you really crank up the voltage for a bit and run it hard....unfortunately you need good cooling to handle it and not everyone has that. It might work at lower speeds with a high voltage burnin, but I doubt it.
Anyway, for those of you who have decent cooling and want to lower temps....raise the volts of your CABNE, burn it in and temps will be MUCH lower.
Perc--the BSODs at 3100MHz is just what happens when you run at an unstable speed, eventually it'll crash Windows.

im on water, and i can turn my fans up to high for this burn in. how long you think i should run that for? a day? 2 days? i DEF need the positiv burn in effect to essentially make sure it puts out as least heat as possible at or below 3ghzQuote:

When it fails, restart it, keep repeating that process until it works for a VERY long time and then drop the voltage down again.....yes, it takes a while but it DEFINITELY works. You can't lower your usable voltage as far as you want but it's often good for lowering it >.05V.
Of course, a high OC/voltage combo on these requires serious cooling still.....but I'd recommend the method I just wrote out for you el rolio.
Mine was as hot as my X2....these are very hot processors until you break them in (which not many people have done yet).Quote:

vapor: im not getting the blue screen the system will just lock up and like i said it doesnt do it all the time the system can run for 2days or 10mins its random when it does this....
peace perc,
then I can't expect it to outclock an excellent X2 that I've already got then.....my X2 4200 is dual prime stable at 3.0Ghz @1.53v.
perc....are you running with the max multiplier? I had a similar problem where my PC would lock up....turned out it was raising the multi on its own and my CPU couldn't handle it.
And you're only at 3100MHz on phase? I could easily do that on cheap water....you have a whack setting somewhere (or a very bum CABGE).

well its not stable at 3100mhz using 1.55v in the bios im not using my % settings yet so i have some voltages left if i need them. also im running with the 10x multi i dont know how it could raise the multi its self could you explain? i also suspect a bumm timming cause this chip will run 3gigs at the defualt v-core wich usaly is a good sign. the stepping is the famos 0530APMW CABNE. i dont think theres anything wrong with this cpu i think its me... ill figure it out also any tips would help as well.
peace perc,
Alright, you're running the max multi, it won't change....
The bad timing you have is probably preamble...what is it set to?
7.5 i went back to your settings. hey when i get off work ill get ahold of you maybe we can compare notes see if i got something set wrong? also i only have like 8 hrs burn in time with this cpu maybe i just need more?
thx perc,
Post a Tweaker shot and I'm sure the many memory gurus around here will point you in the right direction.Quote:
