3700+ is the "rev2" (as I call it) of ClawHammers; it's already the same thing as FX-53.. Although; those were discontinued for FX-55, and they probably still make 3700's. So, quite possibly, in some time, the "rev2"-based ones will be phased out; and replaced by "rev3" - same thing as 4000+ / fx-55. Or, maybe not replaced, but, rather a new line of s754 chips - 3900+, anoyone?

Older ClawHammers have the C0 revision, as denoted by AP at the end of the product code. A64 3700+ has the CG core, as denoted by AR at the end of the product code. All true Newcastles have the CG stepping, as denoted by AX at the end of the product code (note when the S754 A64 3000+ was first released, they were just ClawHammers which had 512K L2 cache disabled so they were C0). The Winchesters now have the D0 stepping, there will be a new stepping early next year, E0. The FX-55 has the CG stepping, just with strained silicon. A64 4000+ = FX-53 with higher multi's locked.
 
Yes, I do realize that they are all "CG"s, but something was altered to make the 3700+ perform much better than it's 3400+/3200+ brothers.
 
it was just a chip from a better part of the die, nothing more.
what do you think the barton mobiles were? just regular bartons capable of hitting the same speed at lower voltages.
the 3700+ is essentially the same thing, but instead of reducing voltage, they bumped up the speed.
however, i'm mighty tempted to look into a w.c. setup with a 3400+ mobile. 2.2ghz at 1.4v is bound to be good for something at 1.6-1.7v ;)
 
Ok; it's been pretty much beaten in to the ground that 3400+ doesn't overclock much better than 3200+, if at all - somethimes, 3200+ actually pwn their pants. Now, along comes a chip that can hit 2.8GHz at about 1.85-1.9vcore, along with FX-53, which pretty much does the same thing. Now, doesn't that strike you as odd? I mean, some 3400+ should have been at least to get somewhere close to the overclocking potential of 3700+, right? Just like 2400+ Barton-M vs 3200+ Barton; M or no M. Some rogue 2400's were just as good as 3200's..
 
It's called speed-binning and AMD getting used to the manufacturing process...if there was a revision, AMD would note it in their PDF or product code. A64 3700+ is guaranteed through speed-binning to run 2.4GHz @ 1.5V. Maybe sometime in the future the manufacturing proccess will become so mature that a Barton 2500+/3200+ situation rises again :)

amazing! running memory at 170mhz. the power supply in my sig isnt here yet, running on a antec true 430watt with 20amps on the 12volt. so thats holding me back and that explains the rail fluctation.
 
nah that 20 amps on the 12v wont hold you back. whats holding you back is the fact that your only running 1.39v on the vcore. thats nearly impossible. for the simple fact that the defualt voltage for a 3200 mobile chip is 1.4v or 1.44 i cant recall. and your running a 939 which please correct meif im wrong is not a mobile chip. now im a little ignorant on the 939 chips so if the 939's run low volts let me know.

so up your vcore voltage to like 1.5 or 1.55 and you should reach alot higher. the chip should handle 1.6 no problem also. again assuming the 939's run the same voltages as the 754's

but also remember that 2.5ghz is pretty mucht he limit for the 3200+'s

you got a sweet overclock with some extremely low voltages. raise that vcore and go go go.
 
3200+ and socket 939 = winchester (90nm)
this means his stock voltage is 1.4v, so technically he's at stock, but still, that's a very nice oc for stock voltage. most people i've seen need to bump it up to 1.5v to get those speeds.
and jsut so you know, the voltage for a64 mobiles is 1.4v. most chips can run lower than this anyhow, at stock, my 3200+ clawhammer can go down to 1.3v without faling a 24h prime test.

So far so good. Just upgraded and I must say this motherboard is great. Everything is going smoothly. I've primed for 10 hours at this speed. I know I can go higher, just making sure it is 100% stable.

Hot damn I am loving what these winchesters can do. Gunna start on mine after christmas. One thing I am noticing is there are some really good overclocks at stock voltages...why? Do the winchesters not benifit as much from higher voltages, or do they get to hot, or die easier at higher voltages? I am going to be running on a Venus 12+, which did a damn good job keeping my 2800+ around 80F at 1.7v....so if heat is the facrot for all the low volt overclocking, I think I will go about 1.6v. Think that would be safe, and benificial?

Yes, but chips below week 32 don't do this, while after do. So, either they started using SSOI cores on them after week 32, or the core got tweaked otherwise.
 
Viper, very often they don't benefit much from it, they don't really get any hotter than the NCs from what I've seen. Some boards also have trouble getting the proper voltage administered if you bump it unless you update the BIOS.

edited : put my timing from 2T to 1 T and got this ..... :D :D

wow, what timings is your ram at? i would expect well over 6000mb/s at 240mhz
also, you didn't state which motherboard you have ;)
 
ahhhh, it was cmd 2t.. that would do it.
1t is definitly the way to go unless you can get 300+ mhz out of your ram when using 2t
 
thanks for pointing that out guys .. i was kinda like.. ehh my memory score is kinda low compared to same processors at realtive speeds... ^_^
 
the bios tries to make the ratio 6:5, but if it can't get an exact ratio (remember, a64's use ram dividers) it rounds up, which makes your ram a bit slower than it "should" be

Impressive. What specs you ran with fx53 ;)
Edit: can you benchs with sandra or everest at this setting? reason is I want to compare it with fx55 at the same setting to prove that there is not much difference between 53 and 55. Thanks :D
 
Got the 3200+ to 2.25GHz with a 9x Multi and 250MHz FSB with a 4x HT bus multi.
Not so bad, but I'm running @ 1.5V on the processor(Which I'm a lil' disappointed in right now). It's Prime stable so far for about an hour, and I'm gonna let it run through the night.

I was at 2.5GHz(10x multi with a 250MHz FSB), but couldn't get prime stable for even a second with the voltage all the way up to 1.6V.

What is the highest you fellas would try voltage wise on air>? Anything over 1.55V seems like a lot to me, and since 1.65V won't help @ 2.5GHz, should I settle @ 2.25GHz with 1.5V?

I ran memtest86 for about 5 hours with a 250MHz FSB and 9x multi with no errors, so I'm guessing it's either the motherboard or processor holding me back right now.

Where in gods name are you guys changing the multiplier?????? :confused: :confused: :confused:

I can't find anywhere in the BIOS to change the multiplier. In the "jumperfree" settings, I can change the bus speed, and I switch the auto speed to manual, and then I get to chose the speed from something like 800MHz to 2000Mhz, and only then can I change the voltage settings for the CPU...

I'm very confused. If anyone can help me get some sort of OC'ing set with my bios, I would be very thankful.

Thanks very much in advance.
 
Hey guys, whats the maximum voltage I should crank to my CPU ( Skt 754 3400 1Mb CG ) Right now, my temps are around 34* idle @ 2400Mhz ( 1.67v )


And SmartGaurdian is the software DFI ships w/ the Lanparty UT NF3 to the post above me.

Oh, damn. So its onyl for DFI then? I really want something that can monitor DDR Voltage. Also, I think your current voltage is about the max you wanna go. I ran my 2800+ at 1.7v, but even at 30C idle, I didnt want to go any higher.
 
after about 1.65-1.7, it seems to stop adding to the clock speed and just making more heat..
unless you can get it under some water or vapo, 1.7v would be the most i would do for everyday use
 
I have my 3200 winchester at 2.4ghz (10x240 with memory a 200mhz). For some reason I can't overclock my ram 1mhz without crashing. Does the Neo2 not like BH-5? I tried each stick individually and it still crashs at anything over 200mhz. 2.85v doesn't even help. I know all my settings are right but this ram just will not budge.

Lanparty UT board, 4000+ Corsair XMS. Running a 1:1 ratio on the memory.

This was also on a stock cooler. It would post and get into windows at 280x10 (not with a 1:1 ratio) but the heat sync would get totaly heat soaked.

Is this a good OC? =)

Impossable. The Lanparty UT is a s754 motherboard and the 4000+ is a s939 CPU. I smell bullshit.
 
Er ya lol this was the A8V, the system the Lanparty UT was in has a 3500+ that won't get stable much above 250.

That was the first 939 system I've had my hands in and it was great. Very fast even at stock speeds.

Anyhow it's not BS just me being stupid. Belive it or not I thought it was a pretty good OC

Yeah, that is a pretty good OC. BTW, a 3500+ on the UT isnt possable iether. 3500+ is s939 only. ;)
 
Christ I"m gonna leave the stupid lanparty alone, but it was either a 3200 or a 3400.

I mainly wanted to post it to see if it was actually worthy or not.
 
if its a 3200+ which is 2.0ghz 250mhz is the max your gunna get,,, that makes it 2.5ghz not many people go over 2.5ghz with the 3200+

2.5ghz seems to be a limit for alot of the socket 754 chips so dont feel bad. even the some of the 3400+ chips wont go over 2.5ghz.

the socket 939 chips on the other hand they go higher.

but if you dont want the lanparty let me know i might buy it from you hehehe...
