AMD Athlon 64 Mobile CPU... Overclock Friend ??

[airjetline]

I'm looking for a lucky Athlon 64 Mobile CPU....for records on my future DFI

There are three kind of Mobile 64 CPU. The 32W, 65 W and the DTR ( desktop replacement ).

Which of one is the best for overclock? The 32W? Can I find it on the web?

the 32 watt one is only 512K cache so it will perform badly.

I think most people are using DTRs, not sure the exact reason.

[Arkangyl]

DTR's are CG steppings (only the 3200+'s)
basicallly they are the only reliable 1mb L2 CG CPU's out there...

also with the A64's there is NO oc benefit to the lower watt mobiles

http://forums.anandtech.com/messagev...eyword1=mobile

that thread covers everything mobile, the starter has a very nice mobile intro too...

[airjetline]

But for example the DTR 3000+ is 1800 Mhz at 1.5V, and the desktop 3000+ is 2000Mhz at 1.5V.....

There is anything wrong.. I think...

I don't know the powerful of DTR cpus, but I think they aren't very overclockable....

The 3000+ Mobile 62W is better... 1800Mhz at only 1.4V

The 3000+ 35W is 1800 Mhz at (ONLY) 1.2V

Nobody has got a DTR, a 35W or a 62 W Athlon 64 Mobile?? Are they overclockable well??

[majewspj]

I think DTR are just heat spreadless. Do they have a different micro code ? Since mobile 64's dont want to work on most boards correctly ... but it looks like if you want socket 754 and 1 meg of L2 then mobile is the only way to go.

I have a mobile 62w clawhammer 3200+ and it does 2.65 stable.

[Arkangyl]

did you read that link I posted??? those guys have done TONS of tests and the lower wattage does NOTHING; since you seem unwilling to actually read what they've done I'll summarize for you;

~1.2v, 1.4v, 1.5v; they'll all OC the same, unless...
~CG steppings will OC farther than C0 steppings (AR and AX = CG, AP = C0 thats for s754 only mind you)
~1mb L2 is 5% better clock for clock and 512kb L2
~a 1mb L2 and a 512kb L2 both with the same stepping can achieve the same OC speeds

morale of those bullet points; the 3200+ DTR is the only surefire 1mb L2 CG Athlon 64 meaning it has the best possible OC core and will be 5% faster than if you got a Newcastle (512kb L2) to the same speeds.

so....

Buy the 3200+ DTR (the 3400+ and 3000+ are AP steppings or the C0 cores which dont OC quite as good as the CG's)

1) did you read the link you posted?

2)wattage does count

3) newcastles overclock way higher than clawhammers. Newcastle 3200 chips do 2.5 on air, clawhammer 3200 chips do 2.5 on vapo.

im sorry mr. boshi, but thats just not true

I have a 3400+ CG Clawhammer coming from tigerdirect. Punched the OPN code ( ADA3400AEP5AR ) into google, and up came the link to it. It is in transit. However, I won't believe it is what it is said to be til I see it.

Cooling? Vcore? Stepping?

I would also like to know.

5) So, I want to go mobile, but which CPU should I choose?

Here are some factors to consider:

(a) The difference between 1MB of L2 cache and 512k of L2 cache at the exact same speed is approximately 5%. What that means is that you would need for example a 2.1Ghz 512k L2 cache Athlon 64 to equal the performance of a 2.0Ghz 1MB L2 cache Athlon 64. So, obviously since all CG cores overclock to the same range, 2.4-2.5Ghz on aircooling, one should prefer a CPU with a full 1MB of L2 cache.

(b) Get a CG core. Simple. They overclock better and run cooler

(c) Given the choice, the obvious CPUs to select are the 3200+ DTR or any of the 1.4v mobile CPUs. These all feature a full 1MB of L2 cache for maximum performance. Please note that the lower the speed the lower the mutliplier of the chip and the higher the HTT/FSB needed to get a succesfully overclock into the 2.4-2.5Ghz range.

(d) Wait, but aren't the 1.4v mobile Athlon 64s much cooler running than the DTR processors? Actually, no they're not. Remember that when AMD rates thermal output they only give the max output for the single top of the food chain CPU. Thus, for the desktop and mobile C0 revision, the highest is a 3400+ at 89W. For the CG revision DTRs the highest is a 3400+ at 81.5W. Now here's where you need to pay attention. The highest CG revision 1.4V mobile CPU is the 3200+ and NOT the 3400+ so the TDP listed of 62W cannot be compared to the other CPUs. In fact, if you compare it to the DTR CPUs and do a little guestimation (don't know if there's a linear relationship between clockspeed and heat) you'll see that these are basically CG DTR CPUs running at 1.4V These are just rebranded DTR CPUs.

(e) But still, shouldn't the 1.4v mobiles overclock higher than the CG DTR? Not at all. Given the choice there's no reason to not pick up the 1.4v mobiles but all CG revision CPUs hit a wall at ~2.5Ghz with aircooling, whether they default at 1.5v, 1.4v, or even 1.2v

directly from the link I posted buddy, all CG's, Newcastle or Clawhammer are doing round' 2.5ghz (for them anyways but they've tested tonnes); also watts might matter if your using a little 200w PSU but since CG's hit a wall at 2.5ghz (max air seemingly) it doesn't matter what voltage you start at...

[mad mikee]

bandwidth on my mobile (3200+ CAABC ) CANNOT do 2-2-2 at
anything over 205, waiting for my CAAPC to see if any better.

NC-CBASC may be even better, haven't tried it yet w/ coherent tests

watts matter because they allow you to turn up the voltage farther.

also, I dont know where you're getting your info, but a clawhammer 3200+ isnt gonna do 2.5 on air or water.

A CG stepping chip has a good shot at it.

hahahaha... I'm tempted to send you my CG desktop 3200+ just to prove my point...

[Shade00]

You might be right about the desktop chips. I haven't seen a whole lot of desktop CG reports (except for the 3700+). DTRs and mobiles routinely do 2.5+.

[Arkangyl]

boshi, in cause you missed this both times (or is it 3 now?) that I've said this; the CG chips are maxxing out @ 2.5ghz on air weather its 1.8v or 1.2v, you can feed it as much voltage as you want but the point is it probably won't move. Your sig shows a 1.5 P4A; the people I'm quoting have actually used these chips, they've used the DTRs, 1.4v Mobiles, 1.2v Mobiles and those are their findings, believe it or not with these A64's the lower voltage chips seem to OC the same..

[airjetline]

The 3000+ DTR step CG is good for overclock?

[garetjax]

Hey,

Check out the o/c results taken from this thread http://www.ocforums.com/showthread.php?t=319185

I am looking for a new chip for my DFI that should be on the way. Looking at those results the best bang for your buck seems to be the 3000 CG. Any one else have any thoughts?

in case you missed it, I've owned two A64 CPUs and three A64 motherboards so far, and I'm just using this P4 while I wait for my motherboard to arrive so I can put MY 3200+ CG which I was running before in it. Read Jeffs sticky on the topic. The CG 3200+ desktop chip maxes out at 2.5GHz under vapochill. It will not do that on air. My C0 3400+ on the other hand does 2.5GHz on air. I am speaking from experience, not just out of my ass .

Whereas you on the other hand, do not appear to have owned an Athlon 64 chip before, and I understand your confusion about it. The Athlon 64 desktop chips are not like the athlon XPs. They overclock according to their speed rating. The 3200+ will do about 2.3, and the 3400+ will do about 2.5. I dont have any experince with a 3700+ ( I'm about to order one though ) but I would expect it to do around 2.7 on air. AMD seems to have speedbinned them very well.

[Arkangyl]

In all fairness you've admitted no expierence with the Mobiles though which puts us on the same grounds; I'm not trying to say anything original, I've just been quoting what Bar81 has said and his information is based on about a dozen or more people who've tested the mobiles, all varieties, most every speed rating. And thats what he's discovered.

What you seem to be unwilling to admit is that the Mobile chips do not seem to folllow the same pattern as the desktop chips.

I'm not saying anything about what I think desktop chips should or do at any time, I'm saying what Bar81 and many others have and are saying about the Athlon 64 Mobiles and DTR's

I'm sorry, I was referring to the desktop chips, as you said "all the CG chips".
