Guest LithoTech Posted May 8, 2006 Posted May 8, 2006 Timmay where did you get that Smarguardian version? Check here: http://www.dfi-street.com/forum/showthread.php?t=24388 Just found this myself, looks interesting. Share this post Link to post Share on other sites More sharing options...
q0nk Posted May 13, 2006 Posted May 13, 2006 The use of the word "stepping" in this thread is kind of a bastardization of the term. Technically, you are correct, the stepping is E4 (versus E3 or E6 for Venice, etc.). However, the second line of text printed on the IHS is commonly referred to as the week/stepping. There is probably a more accurate term, but stepping works well enough. Sorry for the confusion. so does this mean that E4 = CABNE, CABYE, CAB2E and CABGE ?

ixtapalapaquetl Posted May 13, 2006 Posted May 13, 2006 so does this mean that E4 = CABNE, CABYE, CAB2E and CABGE ?Holy blast from the past! That was like 1644 posts ago! To answer your question, yes, all the "steppings" you mention are the same stepping. Share this post Link to post Share on other sites More sharing options...

Guest akahai Posted May 19, 2006 Posted May 19, 2006 Anyone got the new 144? stepping CAB1E 0614 BPBW (not exactly sure about the last four letters) I got it to run 320MHZ FSB with stock volt on my SLI-DR, want to know if anyone try it????

flatfinger Posted May 24, 2006 Posted May 24, 2006 Im currently waiting my opty 144 to arrived this friday.. the stepping is CACJE 0606 CPAW anyone got a reviews??? thx u Share this post Link to post Share on other sites More sharing options...

SRT-4me Posted May 26, 2006 Posted May 26, 2006 I just put in my new Opteron 144 CAB1E and had a quick question. I had it running at 2.7 Ghz (300x9) on stock voltage for a while and it's been running great. To cool it down a bit more, I've dropped the voltage to 1.26 volts, and it's still running great (and much cooler). Is there a minimum safe voltage? I'm guessing I'm not going to damage anything by going too low, but I just want to be 100% sure. I would assume it would just become unstable. I love this chip!!

Redrum Posted May 26, 2006 Posted May 26, 2006 I wouldn't think that low voltage would hurt anything except for stability. I ran my 146 Opty for weeks at 250x10 at 1.225 volts 12 hours prime stable. Share this post Link to post Share on other sites More sharing options...
Sorrento Posted May 26, 2006 Posted May 26, 2006 I don't think anything is damaged because the current also drops when you lower the voltage, so all the inner circuits are safe. The only problem I can think of is when using high voltage RAM, something to do with the memory controller inside the CPU needing a balance voltage as well... but if using RAM with a high voltage of 2.8v shouldn't be a problem... and this is just a theory of course.

Thunda just pointed this out to me in the OCDB discussion thread: Be carefull when pumping so much vdimm while leaving your vcore at stock.. There is a thread at XS where Tony from OCZ said that its bad for the cpu to run such high vdimms with very low vcore.. It has something to do with the memory controller I think.. Here is the thread ! http://xtremesystems.org/forums/showthread.php?t=79509 It should only come into play when running ram with more than 3.2 volts. So basically, if you flip the voltage jumper and have a newer cpu with low voltage, bump the vcore up a bit to strengthen the memory controller diodes, thereby protecting it from the extra current coming from the ram. The link is a scary but good read. Frightening topic for sure! I think AMD should have this documemnted better, somewhere. There are a lot of BH-5 kits out there, and a lot of people running very nice overclocks with stock voltages. The chips lately, Opteron especially, don't scale very well with voltage, but clock very fast on stock voltage. Hence, this problem is undoubtfully getting more common because more and more people are able to achieve clockspeed goals without increasing vcore. So I used to run with stock vcore of 1.4v and the vdimm at 3.3v. In this setup, I've bumped the vcore to 1.45 or 1.5 with very little heat increase under load. In certain circumstances/setups, I've found that bumping the vcore, even a little bit has produced errors in memtest where stock vcore has been rock solid. So otherwise, I would simply resign myself to runing a notch above stock at all times. . Share this post Link to post Share on other sites More sharing options...
sofarfrome Posted May 26, 2006 Posted May 26, 2006 Just installed brand new OEM 144 opty purchased new off of ebay ($131 shipped). Priming right now at 325HTT (2.925FSB) 1.37Vcore. Using a modified 406 bios. The only changes after resetting bios (was using a A64 3200+ that I could never get above 2.6Ghz, NBBWE stepping) was to manually set the timings (2226) and Vdimm to 3.5, disabled some peripherals, manually set the Vcore to 1.4V and cranked it up to 325HTT. Mem is running on the 166 divider at 266FSB. Load temp is 41C via smartguardian. Prime has been running 2hrs...hopefully it will run over night then I'll get down to some serious tweaking. The person that sold me this CPU has 29 left but she won't tell me if they are all the same stepping. This one is very good so far.
