3700 San Diego KAB2E, KAB3E or the 3700 E6 Stepping San Diego (Actually a Toledo DC)

I just realized that my new 3700 Sandy is a KAB2E, is this good or bad? I wish I was lucky enough to get sent a KAB3E but fate wanted me to have this. What do you guys think? Is the KAB2E just as good as the KAB3E?

What kind of OC's are you all getting with both of these steppings?

There is another 3700+ San Diego Model #ADA3700CFBOX that has E6 stepping instead of E4. Has anyone got any other info about this other proc? 1st. 3700+ San Diego CPU #ADA3700DAA5BN or this 2nd. 3700+ San Diego CPU #ADA3700DKA5CF Anyone have this proc that can elaborate on its OC'ing abilities? I debated about getting it when I bought my 3700 Sandy, I am now wondering if I had made a mistake. I have done a lot of info searching about this other 3700+ processor and found out that it was a dual core toledo that has one faulty core so AMD disabled it and is selling it as Athlon 64 3700+ San Diego Model #ADA3700CFBOX . Not to sure of what to think about this.

It's a great core. you can do 2.75Ghz no problem and with good colling you can push 3.0Ghz on the right V.core

I'm building a system tonight with the same processor/stepping, so I'll let you know what happens. As far as this being a disabled dual core processor, that's rediculous. I'm going to be using it with an MSI Neo4-F, so I'll know what the chip can do. I've had very good results with this board and 3700s. Because of the computer's owner, I won't be leaving it at full OC, but I'll play with it before I tone it down. He bought a Big Typhoon too, so let the fun begin

I'm quite positive my 3700+ is a KAB2E and the thing is freaking awesome. Can hold 3Ghz 24/7, 1.55 vCore with my Zalman 9500. Mine tops out at 3.21Ghz, but that is limited to 1.55v... (not temps, took it outside to hit 3.2Ghz, CPU idled at 7C)

On other forums, there have been some instances of people trying to enable the second core on the other second model 3700+ Sandy. No one has been able to do it. It would be cool if it were possible.

If it were faulty, it'd probably make your system unstable, thus they disabled it.

If you take off the heatspreader, it'd end the mystery. I'm fairly sure it can't be though because they're being sold as a San Diego core. If that is not what's being received, then you were misled and that's not legal.

Thats exactly what I am thinking but I am also wondering why there is another San Diego with different stepping and model#. You would think it would be the same model# with different steppings like KAB2E and KAB3E, you know what I mean?

Thes 2 quotes are from the AMD forum.

Quote:

Recently i ordered a ADA3500CGBOX , AMD 64 AHTLON , I ordered it off a website called NEWEGG, the processor is advertised on as being the "VENICE" core, 939, 512kb cache. I recieved it and it registers as a "MANCHESTER" core(CPUID)(CPUZ).? My understanding is that the "VENICE" core is a better core and it was my belief that the "MANCHESTER" was a cheapier core designed for inexpensive X2 processors. Im confused, I didn't know that the "MANCHESTER" was used for non X2 processors, and why alot of distrubitors are advertising this model number(ADA3500CGBOX) as a "VENICE" core if it's clearly not. Thanks in advance for your help.

Quote:

The Processors with an OPN that got the CG surfix are Manchesters Rev. BH-E4 and the ones with a CF surfix are Toledos Rev. JH-E6, in both cases an entire Core is disable. Because Manchester and Toledo are two Venices and two San Diegos in the same piece of silicon respectively, if you disable an entire Core from these, then you get the same performance than a Venice or San Diego with the same specifications.

I have no idea of what AMD is doing.

I think this is along the same lines of the 6800GT with 16 pipes and the 6800GS with 12 pipes. The 6800GT had faulty pipes so they disabled them and sold it as a 6800GS with 12 pipes instead of 16. Then when the cards get into our hands, we use RivaTuner to open the other pipes. Theoreticaly we could do the same thing with a faulty DC proc.

I don't know what the facts are, I am only going by the research I have done on these two models of 3700 San Diego's.

this is really interesting... I wasn't aware that AMD was selling dual cores w/ one core turned off as single cores... if there is a way to enable them then I see this as the next big fad.

I just go the ***3700KACF from Newegg this week, These are E6 Steppings.

Got it stable at 2.75 Gig, no problem, on a Zalman 9500

It's running about 39-40C loaded

But seriously, and maybe you can help me Crash.

I tried to set the FSB to 260 but the system was most unstable.

I tested the ram at 240, I'm running a 9/10 divider so I should have plenty of headroom on the RAM.

I suspect it has something to do with the PCI-E Frequency and the SATA

Can I lock the PCI-E Bus Frequency or is it already locked at 100 ?

it should be locked, but there will be a spot in your BIOS where you can chang it and/or make sure it's locked.

what is your htt multi set at? 4x is good for up to 250, but above 250 you need to bump it down to 3x. if you forgot to do this then we've probably found your problem

if you feel like you're running into a wall then run through this:

that way you'll know what component is holding you back and you can act accordingly to get a higher OC.

Set PCI to 33 and PCIe to 100
You may need to up the nForce chipt voltage along with the LDT (Mem ctrl) voltage to help with stability.
Soloz is refering to the LDT multiplyer

yep, thanks for the clarification. I'm still used to the BIOS from my Asus board... still trying to figure everything out w/ my DFI. htt multi/LDT multi are the same thing
