opteron 148 vcore and temps advice

[scruffy1]

well as per sig i seem pretty stable

 

but i have lost mbm5 as a monitor (no a8v support) and have to rely on asus probe huh? for my readings

 

it says the 12v rail on the antec is 11.369 ??

and that the core is 39c after an hour's prime

and vcore is 1.472 - 1.488 (fluctuating per the readout) from cpu-z

 

is this just crap monitoring, or is it acceptable ?

 

i'll try my "new" 350w antec psu

 

what i really wonder is :

 

what should operating temp be under load (max, stock cooler, though i'll upgrade to the si97a next) ?

 

what is the normal range vcore for the opteron 148 - 1.35 (to 1.45) ?

 

i presume my vcore is pretty modest really

 

comments and advice please

Rule of thumb is not to exceed 1.65 vcore. Although I have reached 1.7 myself with my Opty 165, prime stable and cool. With that being said it is @ what vcore you are comfortable at with your ability to control the heat being generated by your vcore. Take my Opty for example after tweaking it out, I am running it at 1.6 and using a Zalman 9500 and it runs idle at 33-36, Prime load at 45-50 for at least 8 hrs. Its your cooling ability is what plays the most part, because as you reach your max speed you will want to tweak to a lower vcore at its top speed. For example, why run a 1.6 vcore @ only 2.8, when you can run 1.45 @ 2.7 right. Its why a lot of folks try to get as high as they can get at stock vcore and work from there.

i'm now at 39c after 2.5hrs priming

 

but do i trust cpu-z for readings when the vcore is 1.472 (to 1.488 variously)

 

if 1.35 is good, 1.45 ain't bad ? - it's on auto for the setting per my mobo196 ram

the only things i have personally rated is the ~196 mhz @ 2-2-2-5 (default is 2.5-3-3-8), 250 fsb;

and the vdimm to 2.8 (bh5's , so wth) and the 2T to disabled

 

but as my xp runs at "stock" 1.65 max to o/c to 2.3 what i really want to know is whether i am pushing the silicon very hard :confused:

I would think a 350w PSU is a little weak for that project...You might get away with it from stock but not any higher...

 

EDIT...the CAB2E's are good for 2.8ghz on stock vcore...Mine is..but it ends there...they dont like to go any higher without lots of volts from there..I could get 3G's but it took 1.62v to get it..even just a bump to 290 took a big jump in volts...good luck though...

just upped the 350w psu from a 16amp to a 21amp +12v rail - both antec, but the new one is a trueblue from a lanboy

 

when i swap it over to the sonata case it'll get 400w smartpower 2.0 instead, so i may tweak a little more from there

thx for the advice; i'm on 1.45vcore for 2750 and testing

if that's where i get to without any hassle i'll happily settle for it (but i'll push it a bit further anyway just to see)

after a few crashes testing with hot cpu tester i reset the memory to stock 2.5-4-4-8 1T (noting that it ran 2-2-2-5 at 200 on my socket a, but had the virtue of 2.9vdimm on the a7n8x with modded bios)

 

seems now happy on this at 2750 on 1.44vcore after almost 5 hours.. it seems the problems must be ram settings being too tight initially, but interestingly both sisoft sandra benchies are unchanged regardless of the ram latencies... whatever that means in real life applications

 

is there a bios mod to get me more vdimm for the bh5's ?

 

what's the mysterious v-link voltage adjust do ?
