im just about to thrash a new opteron 144, CACJE, manufactured 0508 (i think, its not infront of me atm) its only on air, under a freezer64, what is the general census that i will be able to get out of it?

i have had an older CAB2E for which i had high hopes but it barely crept above 2.65ghz before it flaked out and nothing would help me get beyond that
 
iirc the CAB2Es were variable. The CACJE more consistent - though your week number doesn't make sense to me. Decent 144s should easily go over 2.8 - a large proportion will go to 3.0 or better. You didn't state your rig so you may have mobo, memory, cooling constraints from other components. If you give other details, I'm sure someone here would identify any bottlenecks and help you get the most out an excellent CPU.
 
oh its sitting in a test rig, which is a DFI ultra which has no trouble and the memory is gskill 4400LE which i have verified will go to 310mhz from previous OC's, psu is an ocz, its had a few cpu's in it now, the last was a 4000 that went to 3ghz in the exact same setup but with a water block on it, i am confident the rig wont hold up the cpu :]
yeah not sure bout the week number, bought it off ebay and it arrived this morning so i was trying to read the fuzzy number off the pic he sent me but that was my best guess, anyways i just wanted to get some general numbers to aim for after my cab2e which was plain dissappointing really
 
Most of the xx06 CACJE Opterons have been good clockers. My 0606 CACJE 146 did 2.95Ghz and I'm pretty sure that was only limited by the board (A8N-SLi).
 
well i have a freezer 64 atm as the water is now in a dedicated rendering system so its out of action for thrashing CPU's these days, if there is an air cooler that isnt too expensive that will give me far more performance than the freezer i might shell out for it
 
i was thinking about doing the same on mine, as mine has a really concave ihs (60c load on 1.45v :o) so it runs at 1.4v to keep it under 55c load.

a quick google suggests the stepping you have looks to be a decent one, with most getting 2.9ghz on low vcore ;)

well im in the process of OCing this chip now, thats the maximum stable OC i can get on air at the moment, its at 1.48volts so im thinking if i up the volts a little more maybe i can get over 3.1ghz, it runs very cool, im not sure if thats because i took the IHS off or not, but it peaks at about 45 degrees
not bad considering its default is 1.8ghz and it only cost me 30 quid :D

how hard was it to take the IHS off, i am still meaning to do mine, 1.4v and still hitting 56c :(

i can suicide up to 3.4ghz so i am sure it has more in it its just the heat thats killing me :p i can get it stable at 3ghz with 1.45 just 60c isnt too good. looks like a trip to the chemist for some razors may be in order.
 
Its not very hard to take the IHS off in my opinion, if you go through that sticky on the forum and follow that its a good guide, ive taken it of this and my xp4000+ and they were both relatively straight forward. First time was a little more scary as i wasnt sure how much pressure to apply and how far in to insert the blade. As it happens single core athlons actually have a lot more space between the inside edge of the IHS and the little chips surrounding the core, so you have more leeway than when doing it to a dual core chip.
I bought a pack of double sided razor blades from tesco's, wrapped some layers of selotape over one side so i didnt cut my fingers, then put about 3-4mm of the blade corner into the breather hole on the chip and pushed all the way round. The corners have by far the most resistance, i went round twice to make sure it was all cleanly cut, second time round it pretty much flies round to i didnt need to apply much pressure, then i got out my stanley knife, as its thicker and less bendy, and now the rubber is cut it fits under fine, and used the edge of it to pop off the IHS.
This opteron was making good contact as it turned out, and the IHS looks relatively flat but i guess its one less useless piece of metal between core and heatsink :)
Oh also in that sticky is a list of compatible coolers, although if you have a DFI board i dont think its an issue as all their sockets have a lower lip on them which wont catch a cooler. Im using an arctic freezer 64 and its definately compatible
