The Official AMD 3700 San Diego Overclocking Thread

so my board is undervolting this chip then

saying in bios cpuz and corecenter that its at 1.33 to 1.35

hmmm 2.75 ghz undervolted is very good imo

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:

you started overclocking yours yet then? or is windows still installing ;) or are you still installing software?

Windows is long installed, but now I need to sort out other programs like photo apps, outlook backups and games etc....

I will be overclocking this weekend
 
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]
