A64 San Diego Steppings and Performance

[ziggo0]

Holy crap!

KACAE - Possibly the best chip for air cooling and can reach very high speeds with low voltage. Most KACAE’s will achieve >3GHz, but some steppings (i.e. the 0602GPMW) are capable of 3.2GHz! Unlike the KAB2E’s they do not seem to scale well with Vcore and tend to perform best when at a lower Vcore.

My 3700+ came in today and it's a KACAE! It's not the uber stepping but I'm very excited to see the possible potential for this chip! It will be under water too most likely!

lets see what she does Most likely wont need the water, as your vcore wont be as high, but its still nice to have

Seems most of the retail sandy's now are KACAE

Oh and, Dont forget to burn her in!

I got lucky, i read this post and i was going to re-seat my HSfan, so i checked. Sure enough it was a KACAE. heh, i am happy. The stats are in my sig

Well, I only have the stock heatsink fan but I got all my old A64 WC stuff sitting in a box doing nothing (I was on A64, had to downgrade but im back now). I figure, why spend 40 ~ 60 bux on a high end heatsink when I can just fix my waterblock and use that eh? OH! I don't remember the stock voltage for this chip being 1.35vcore...is that normal? What do you mean by 'burn her in'? Mind telling me what it is or how to do it? Thanks

There is a slight difference in actual vcore and what is set in the bios. It's set to Auto or "Normal" which is 1.35vcore, a small drop or droop

30C Idle on Stock air
37C Load on Stock air

cold ambient though..

Yupp, stock vcore is 1.35. Check this thread out http://www.ocforums.com/showthread.php?t=382751

P.S. i love fresh windows installs

Yeah, I've read it but its confusing...lol. I like them too, Firefox comes stock with mine for some reason

KACAE 0605 here, doing 255x11 @1.376v solid stable, see mi sig

push that to 3ghz !!!

push that to 3ghz !!!

I would do that but where I live the ambient temp are always 30-34ºC, so im waiting the ZALMAN to push this baby to the max

 

[freeagent]

looks good, almost clocks like mine does, except mine is 1.4v stock

Update just for now, I dont want to use cpu divider, I know this baby can go easily to 3.0+ ghz. Later I will try new clocks.

Who needs DDR2??

I put a 80mm panaflo u1a in a shroud on the stock heatsink. Lowered the load temps by about 4C to 49-51C. Still rock stable at 255x11 @ 1.44Vcore.

Not sure how many in farenheit that is, but if your cpu is under 50c its okay to push it. I try not to go above 50 with a64's, definatly not above 55.

KACEA

As of last Monday Newegg was shipping 4000+'s with KACAE /0603EPBW, and 0603EPEW. I'm ready for a shakedown cruise as soon as AS5 cures.
Let the games begin!

I've noticed that they have two 3700 SDs listed. One model number is ADA3700cfBOX and the other is ADA3700bnBOX. What is the difference?

 

[penguin463]

hmm.... every time i try and et my chip past 2.8, it is very unstable, even at 1.5v....

right now i am burning it in to try and get the rated speed i have in my sig at 1.4v. then maybe iw ill be able to take it a little higher. Hopefully to 3ghz.

Dunno the difference, all I can tell you is that I bought the ADA3700BNBOX fifteen days ago and I recieved a KACAE 0605 stepping which is doing fine

CABGE - Old stepping which is not as common lately. Just like the Opteron 146 CABGE they are in general bad overclockers which will usually only reach 2.6GHz-2.7GHz. Fear the cabbage!
KABGE – Similar the cabbage above. They do slightly better and overclock to around ~2.7GHz but still don’t come close to the superior later steppings.

Heh, cabbage
