WOW!..you are burning those cycles up!:D...NICE GOING!Quote:

Yay! I managed to get myself a 3849B028! I placed an order online to make sure I at least get one, but when I got to Micro Center, the one they put aside was C0, so I went to the display glass and asked salesperson to check a few there, first one was another C0, then the second one he got, it's a D0 and B028, exactly what I had in mind to get. The sale is over on the 22nd. I might go back and get a few more of different batch, test them all and keep the one I like, sell the rest.
waiting for your results :up: seems b028 is good, but mine runs hot. I'll probably reseat my true to confirm.Quote:

I will take my time to make it works okay on stock speed first. Well, here comes the bad news. I think I managed to kill my GTX285 in the process. While turning it on for the first time, nothing on the screen. Cleared BIOS, tried again. This time, the screen became filled with artifact everywehere. Turn it off, and turn it on again. Nothing. No signal. Put a different video card in, it works. Put the GTX285 back in, nothing. Nothing. Once, twice, thrice...Put the other video card back in. Works. So, my GTX285 is cold dead. Will have to RMA it now back to EVGA.
Will update with OC later on.
Edit/Add:
An hour and a half later and I'm back. I think it's my board that is limiting my OCing. I get the same OCing result with the new CPU as the old one. So, I'm pretty sure it's just something I'm not doing correctly. Both of these CPUs have high potential of high OCing with the right mobo/memory and expertise like you guys have. Unfortunately, being a newbie, I simply just cannot get the desired OCing experience that you guys can.
Just curious what tempts you were getting stock and overclocked?Quote:

Is that any benefit to change these settings? If yes, to what number?
mhmm i can get a i920 3850A978 exaclty, it ocs well i see as well...
After lapping my True my temps have gone down a lot...it was bad, there was like a lump right in the middle of the HS, just the opposite to concave.Quote:

That's good to hear.... now it's time to crank up that chip and see what she can do on air :up:Quote:

but its not stable enough to get into windows :S , 4850Mhz is more realistic ^^

Tpower can do some serious damage on air but Biostar is no match for Classified on iceQuote:

Nice dude!
Haven't done any suicide runs yet, but I have gotten 4.4ghz bench stable. Batch 3849B028

cky2k6, what board do you have again? Can you give me a complete voltage rundown of your BIOS? Perhaps I can duplicate your settings and see if mine would be stable at 4.4Ghz as well.
I have an asus r2e, its in my sig. 4.4 isn't stable, it wouldn't last a minute of linx, just enough for a few quick benches. Its set for 1.4 vcore, 1.4 uncore, 1.35 nb, 1.3 sb, and 1.7v ram.Quote:

it also completed an 06 run, this chip seems to have very good 3d stability.
It's strange that it's semi-stable but as soon as your run LinX, it crashes within seconds. By semi-stable, I mean I can run CPU-Z, SuperPI and Everest Benchmark. Under LinX, it's a totally different world.
Just got myself a Xeon 3902A250, so far it does 4.0ghz at stock voltage everything with HT on. Haven't tried it further as i'm currently in China, just did a quick run at the shop. Sounds pretty good, they also had a 3849B507 was debating which one but i've decided for the xeon don't know if i made the right choice :(

Looking good eva. I am thinking the 4/28 BIOS is the best so far. I have been having very good luck with the Xeon and the Kingstons. I can push past 2000MHz RAM, but 201*21 is a nice "sweet spot" for 24/7 running. It's just so damned stable and reliable!
Nice going PcCI2iminal, 5 Ghz is tough to get under any conditions, congrats!

Just picked up a D0 3849A866 at Micro Center. Really hoping I can hit 4Ghz on air.
