stuboyle Posted July 2, 2006 Posted July 2, 2006 Guys, I have an Opteron 146 with CAB2E steppings. How is does this stepping rank as far as good or bad one? Could you point to a couple threads? I am currently running Super Pi 32m stable at 10 X 270mhz. I haven't done my Prime stable testing yet. I would be pretty satisfied at 10 X 270mhz but if I could get more why the hell not! After the CAB2E comes 0604DPAW. This might also be important. Was it manufactured in April of 2006? Thanks, Stuart Share this post Link to post Share on other sites More sharing options...
michaelzhao Posted July 2, 2006 Posted July 2, 2006 Most late CAB2E's in the 06 range do pretty well on stock voltages. Usually 2.8 stable. Most CAB2E's in the 0545 range and scale really well. Do 400 mhz on stock, but can hit 3.0 and above at higher voltages. CAB2E 0545 is a really good stepping. But the newer steppings have been performing well.

Evil-Fruits|R4z Posted July 2, 2006 Posted July 2, 2006 Someone over @ XS got 3.0Ghz on 1.45Vcore on an ASUS A8N Sli Deluxe, so you should kick a$$ on your Ultra-D R4z Share this post Link to post Share on other sites More sharing options...
michaelzhao Posted July 2, 2006 Posted July 2, 2006 Actually, not April of 06 but rather the fourth week of 06. You can see my stepping is a 0547. That means the 47th week of 2005. Share this post Link to post Share on other sites More sharing options...
oc newbie Posted July 2, 2006 Posted July 2, 2006 i got the same stepping as you and mine does 2850 on stock volts but to get to 3000 it takes me 1.58volts and runs way too hot for my tastes. Share this post Link to post Share on other sites More sharing options...
stuboyle Posted July 2, 2006 Posted July 2, 2006 Okay, I want to make sure I am clear on this. CAB2E is the stepping and 0604DPAW is when it was manufactured (4th week of 2006). Right? I am currently stuck at 2.7ghz (10X270). At 2.75ghz, my graphics card starts acting up. I get this error saying "VPU Recovery has reset your graphics accelerator . . ." Anyway I can tweek the PCI bus or graphics card? Somone else has told me no, its either the CPU or your memory. Share this post Link to post Share on other sites More sharing options...
ollietwinam Posted July 2, 2006 Posted July 2, 2006 How about CACJE? 0607APAW is on the chip as well That any good? Looking for a 2.6 or 2.7gHz overclock when I get round to building it ... It's a 146 btw Share this post Link to post Share on other sites More sharing options...
FurBurglar Posted July 2, 2006 Posted July 2, 2006 The CACJE 0607 is a pretty good stepping. I have one here that will do 2.8 at 1.45v. Also, it's for sale if anyone is interested! Share this post Link to post Share on other sites More sharing options...

Anyway I can tweek the PCI bus or graphics card? Somone else has told me no, its either the CPU or your memory. Enter the Catalyst Control Centre and turn the VPU Recovery off - that may give you a short term solution. Have you OC'ed the Gfx Card also what is the PCI Bus speed? Should be 66/67 default I believe. TBH changing the PCI Bus speed will not really gain you any performance increase but, will cause instability.

It's a 146 btw CACJE's aren't a bad stepping. They are a okay stepping, maybe slightly behind the CAB2E's, but some of the CACJE's from specific weeks overclock really well. A 2.6 to 2.7 OC is definitely doable though for all CACJE steppings with minimal voltage increase. Share this post Link to post Share on other sites More sharing options...
