Using an NF3 Ultra (Epox 9NDA3J) even back flashed to what is considered the best o/c BIOS of the April 2005 version.

I have an AKASA 460W Paxpower CPU,
XP-120 with L1A Panaflo fan
x800 xt pe

I think the CPU is just a really poor clocker, I have tried with the timings and ram dividers on the lowest they can go - but no luck. So far I have run about 10 hours of SP2004 and I think the clock speed I am at is stable now. Also the HTT is set at 3X (275HTT)

Temps under load are 47-49C :(

hmm I seem to be in the same boat with my 144 locks up @ 285 can run stable @ 280 ?? maybe

You got a couple of those 0542 146s didnt you tatts? Just for reference, could you list each one and what you got with it? :D

Where are you guys buying the 146 right now? Newegg and zipzoomfly are out of stock on them. Does the 148 OC the same? If so, I may just get that since I can find that one in stock.

Here's my 148 CABYE0543 under water

looks like she'll be another to hit 3ghz with a volt nudge

gonna give it the cold treatment in a couple of days ....i hope she obliges.

I've just received a 146 CABYE 0540APMW today. I will post results here as soon as possible, but I have to solve a problem with RAM first that makes the mobo refusing to boot anymore (it seems to be a frequent matter with DFI nF4 Ult.-D).
Anyway, before suffering of RAM problem, I was unable to post @ 3GHz, 1.6V under water... not very promising chip :(

I think it depends more on your motherboard than your processor (Opteron or another one). ;)

Which motherboard do you have?

On other forums they hit 3ghz at 1.5V(cpu-z) with WC.

Check the link in my sig. too ;)

;) I have already seen Répliquant 67 @ bel-hardware.be;

I have to tweak my chip to see what it can really do. Actually, it is hard to believe in a strong difference between chips with the same stepping...

@trans am

A friend of mine got that exact stepping the other day...just called me and told me he was stable at stock volts and 280x10...looks like he is headed over 3 for sure!

i am a foriegner, well i have a question might sounds stupid, but when you guys buy the CPU from websites as monarchcomputers, can you order a CPU with specific codes? Just tell them in the phone what code you want? who can give me an answer, thanks

No, only a handful of small shops do this. I got my CABNE that way from compumusic.

Depending on where you are based and if you have the opportunity to travel... 146 week 0543 were in HKG as of 1 day ago... and you can see before you buy.

I called the same shop and they told me they only had one. I called 3 wks ago and had a CABYE 0540 reserved for me, but I gave it up... now I had to order it form Japan.
the AMD distributor is crap here (not the shop). the distributor didn't even know there was an dual core opty. sad.
