The Official AMD 3700 San Diego Overclocking Thread

how do i get this info

if you just need the basic part - A3700DAA5BN etc then you can use cpu brain identifier, it should tell you. then you would compare the codes to the webpage link that geforce has kindly found ;)
 
I was wrong, I have a ADA3700DKA5CF CCBWE 0542 VPMW
CPU Brain Identifier thinks it's a rev.E5 but MD says it's a rev.E6, default VCore is 1.35V

No overclocking yet as I'm still busy installing after formatting Windows :(

i'd have said 1.55v for air, unless the temps increase quite a lot by the 0.2v? i mean we're ending up with a lot less v's running through the chips, first a64's were 1.55v i believe.

The smaller the manufacturing process the bigger the heat increase will be for the same increase in volts, in other words 1.35V to 1.55V creates a lot more extra heat than going from 1.75V to 1.95V with a XP chip.

so which voltage would you say dutch? if thats the case i'd probably limit myself to 1.45v

I have no experience, I had my 3700+ for 48 hours and will be overclocking this weekend.

1.55V seems like a good limit for aircooling but I think that only applies with good aftermarket coolers, not with a retail heatsink.

But who knows, maybe the CPU runs stable but the increased voltage kills it after a year :confused:
 
hmm i think ill keep it below 1.5v

ive got the big typhoon cooler so its prolly the best about air cooling wise

i need to upgrade my motherboard soon aswell but i need new gfx too going to be ££££££££££££££££££££
 
SD 3700+ CCBWE 0542 VPMW at 9x272 = 2450Mhz@stock 1.35V for now, runs prime stable for an hour but haven't got more time so will continue this weekend.

Mobo ill not go higher than 272Mhz, if I do that Windows will not load, I'm glad I got a 3700+ and not a Opteron 144/146 if 272Mhz is really the max of my DFI mobo.

[edit]So far this CPU/System is a handful, had lockups, prime errors etc at >2450Mhz, further testing is required, I thought I had it stable at 11x250 = [email protected] as it ran Prime95 for 100 minutes fine but at reboot Windows failed to load :( [/edit]
