The Current 3700+ SD at OCuk

[Ixon]

Hi I've just order an Athlon64 3700+ OEM form here so im just wondering are they E4 or E6 stepping and more importantly are they good clockers.

"The E6 steppings are the only ones able to handle 4 sticks of RAM, but whether or not there is any difference in their overclockability, I'm not sure. I do know that almost all of the other Toledo cores overclock very well. "

It sound like the E6 are the newer Toledo dual cores with one core disabled (ADA3700CF) and the E4 are the San Diago cores (ADA3700BN). The CF has a lower voltage as well (.05 fewer volts) due to the new core.

I may not be 100% correct though.

The current crop of 3700SD at OCers are all hitting at least 2.7 on air and 3gig on water

The E4 stepping 3700+ san diego can handle 4 sticks of RAM. At least mine did

Quoting text from another forum, but I agree with you that whichever one you use you would expect all four ram's to work. Mabye the E6 just does it better.

Got mine a few days ago, havent really pushed it yet but its 15 hours prime stable at 2.75ghz 1.5 volts. Dont know if it needs that much voltage but my motherboard seems to be having problems setting the correct voltage atm so i cant properly check. Need to get my multimeter on it when i get back to uni.

The E6 cores have hugely improved memory controllers built into them. This does come at the price of overclockability though.

The new E6 cores are often Toledos with one core disabled. Stepping CCBWE is the most common. VERY poor overclocker on air, but performs fantastically on phase change.

The E4 cores are known for their high overclockability, the KACAE (especially the 0602GPMW) are some of the best air overclockers, reaching over 3Ghz, sometimes 3.2Ghz. They perform best on stock volts.

This is a hugely summarised version of this: http://www.overclock.net/faqs/101138-info-what-different-3700-san-diego.html

All 939 cores can use 4 sticks, just older ones like clawhammer/newcastle will only support them at 333 Mhz. E4/E6 can run them at 400 Mhz np.

Mine hits 2.87 on stock voltage, i can't put anymore through because of the motherboard
