quick question about 3400+ newcastle (2.7ghz achieveable?)

[Alex08]

sorry if this question has been asked, but has anyone gotten a 3400+ newcastle to 2.7ghz + on air?

i wouldnt think it would be that big of a jump since its rated at 2.4ghz and 300mhz seems to be quite achieveable to make it 2.7ghz

so just wondering if anyone has gotten passed that.

i just ordered a thermalright xp-120 and dfi nf3 ut-250.

also if this has been done, can you tell me at what voltage its at.

thanks and cheers xs members.

p.s. i saw a thread for clawhammer, but just trying to keep this a newcastle post.

[blinky]

try it and report back what u get

[Alex08]

i want to, but i only have a 3000+ in my hands :(

was hoping to see some results so that i could make my purchase

[jess1313]

my 3400 NC+dfi NF3, will only do 2570mhz, and be 24h prime stable......

it's possible, 2.7 Newcastle is like a 2.5Ghz Clawhammer, and most would do around 2.5G. (for CG stepping anyway)

i have 2x AMD64 3400+ Newcastles both max so far at 2620-2695mhz... 2.7ghz seems out of reach for air or water right now

most likely need sub zero cooling to get 2.7+ ghz

[oqvist]

Yes I can get 2,75 approx on my Vappochill XE with my fans turned down some. It´s a mobile A64 3400+ Clawhammer though. It´s 100 % stable in everything except FS 2004 but that is hard to say because it do have some bugs so you never know if you crash because your clock is to high or something else. I can sometimes fly for hours though so I think I can say I am stable. But needed to increase vcore to over 1,8 so it may be tough indead with air cooling.

So cooling is quite important the guy before me with a more powerful phase change ran it at 2,85 approx.

Here's my 3200+ NC "4AX" CG. Easily does 2.7 on water. It topps out at 2.8 with the IHS removed 1.75v. It has no problems reaching high HTT speeds.

Newegg still has this stepping in stock. I imagine 2.7 with a good air cooler is a good estimate since my H2O setup is exactly the greatest.

This is why you guys should be buying the 2800 and 3000's... same deal half the cost.

I figured this being an overclocker forum you all would have learnt this stuff by now? All chips are the same in an iteration and stepping..Don't be duped by what AMD decides to charge and label them as... AX newcastle is all you should be looking for and the cheapest one too


Ive seen it all my AMD Life

1700 tbred to 2400mhz
2500 barton to 3200+ (actually 2350Mhz)
Mobile I won't count but 2700Mhz
A64 3000 to 2560Mhz

There is no reason to believe a 3400 will do any better than a 2800 of the same stepping.

[Epsilon]

The multiplier is the main factor to buy a higher rated A64 ;)

3400+ NC has 12x multi
2800+ Claw has 9x multi

[oqvist]

lol I only learned that you should get mobiles since they are hand picked :D

it's possible, 2.7 Newcastle is like a 2.5Ghz Clawhammer, and most would do around 2.5G. (for CG stepping anyway)

That's completely screwed up. You think that because the Clawhammer has about 200mhz worth of extra performance, the Newcastle will overclock 200mhz more? It doesn't work like that.

Anyway, I've only seen one or two people hit 2.7+ on air. I think Mongoose420 has a 3500+ running at 2.7 on air. It's possible, but I don't think I would say it's likely.

[Alex08]

thanks everyone :) very helpful.

hey eva, how many volts were you putting through those chips?

racerx you have a very nice chip there.

well im going to test out my a64 3000+ first, it'll probably do very poorly since it was basically the first week amd came out with these chips. if i dont like it, i'll be upgrading to a 3200+ or 3400+ newcastle.

I just ordered a stick of PQI turbo pc3200 256mb 2-2-2-5 @ 2.6v hopefully these are tccd chips.

I also ordered a stick of PQI turbo pc4500 256mb 3-4-4-8 @ 2.8v and most of you are probably saying wtf is wrong with you, but i just wanted try it to see what the lowest timings i can get with this. maybe hoping 2.5-3-3-10 @ 265+ would be nice

i have 6 sticks of 256mb bh5's lying around to test also. corsair/kingston

[Tedinde]

My DTR 2400+ clawhammer will do 2.7 in air using a Alpha cooler, It's killer chip though, most wont.

[Alex08]

ahh i didnt know DTR/mobile chips worked on a dfi nf3 ut-250. thought there was a problem with those.

That's a myth, that 200 mhz advantage for a clawhammer. Clawhammer itself is only worth about 3.5% performance boost when all tests are normalized. Meaning a 3200 2.0 clawhammer = 2070 newcastle.


All stock
The 3400 newcastle will absolutly destroy both the 3400 Clawhammer and the 3500 939 Newcastle as shown here: http://hardware.fr/articles/496/page2.html

Stands to reason since their 3.5% (for cache) or 5% (for DC) performance boosts can't hope to match the 3400 newcastles 9% Speed advantage. The 3400 NC should have been called a 3600. After all you're boosting speed by 200Mhz from the A643200 (which should have been called 3300), and 200Mhz more from the A643000 (the only A64 with a proper PR rating) and every 200Mhz you boost an A64 = 300Mhz pentium due to 1:1.5 ratio. If that does'nt make sense just look at the benchmarks.

my AMD64 3400+ Newcastles do

2556mhz at 1.55v
2660mhz at 1.66v
2695mhz at 1.75v

[Zebo]

In the end my friend it's all luck of the draw:)

[WildKard]

My A64 3400+ clocks the same as Eva using a Thermalright XP120 and 93cfm Panaflo medium, I could probably get just over 2700 when I get my 190cfm Delta

[mbm]

my 3400+ NC do 225x12 (2700mhz) with 1,65V and inabox cooler.
62C on load, so I am bying a Zalman 7700 today. Maybe it will go further then?

[WeakSauce]

My 3400+ NC will do 225x12 (2.7ghz) @1.55v or 250x11 (2.75ghz) @1.61v both with cpc enabled. Not bad for mushkin lvl II 2x512's. at 225fsb it's at 3.2vdimm and 250 is at 3.5vdimm. Here are some shots to show you guys.

[mbm]

Now I have got my Zalman 7700. IT ROCKS.
Havent benzmarked yet.
But it now do 240x12 (2880mhz) Maybe further. :banana: :banana4:

So as for the topic goes.
the 3400+ NC do hit 2700mhz+++

[mbm]

As time has gone my system has become more instable, and i have declocked to 2640mhz. Not stable any thing over this.
Then I found this thread and saw I had it going at 2880mhz.
What could be the reason for not being able to do 2880 anymore?
