Is it true that Intel will be killing off the line in the next year or two and will aim to have multi-cored dothan based desktop chips on their roadmap?? I swear I read something on this a few months ago but all of this multi-chip P4 talk has got me confused.

It makes sense because the dothan's are sooo much more efficient. I've got a 1.7 pentium-m (the one before dothan) in my laptop and it rocks - haven't attempted ocing it yet though - I was happy with it as it was up until now!!

Dual core dothans are for centrino platform for 2005 only. Desktop will be dual core P4's.

I found the article where I hear this a while ago: http://www.theregister.co.uk/2004/05...cancels_tejas/

But then a slightly later article says it won't replace P4s:
http://www.theregister.co.uk/2004/06...escott_future/

I know they're old articles, I just thought it wise to show the source of my memories. :)

This one is from Today, Dec 13th.

"The Pentium-M processor on this new DFI motherboard continues to put up impressive gaming benchmarks. In both UT2004 and Halo, AMD’s Athlon64 FX-55 processor still puts up the best numbers in comparison to the stock-clocked Pentium-M and Pentium 4 processors, but the Pentium-M is certainly no slouch here. When overclocked, the P-M 2.53 GHz bests everything else on the market"

and

When overclocked – whew, the Pentium-M processors simply fly. In Far Cry, the overclocked Pentium-M at 2.53 GHz is beating the FX-55 and 3.46GHz EE processors by a very solid margin, all with chipset-level technology which many consider to be out of date. :toast:

Their results speak for themselves. :D

I don't think they setup the A64 systems worth crap. They must be running 2T b/c memory bandwidth should be alot higher, which would then definately skew bench numbers down :(

The gamepc test is fubar anyway, because they are running 1024*768 with no AA/AF and the cards are bottlenecking. That's why the dothan @ 2.53Ghz is only scoring 2fps more than the Dothan @ 2.0GHz! Worthless test.

Hmm, its quite the opposite, running in 1024 with no aa or af removes the stress from the video card and puts it on the cpu.

Tomorrow i have DFI and dothan 1.8ghz
overclock possible on air?

thanks

I think 99% of the overclocks in this post where on stock or near stock air cooling. ;)

nice 2.4-2.5gha it's possible? on air?

only thing i ever wondered about is why jan wasn't able to get higher with his dothan. iirc he said around 2.2g was tops for him. hmmm

With a little bit of work 2.6 ~ 2.7Ghz on air is possible.

I went up to 166 FSB 3:4 and @ 3:5 I have had the DDR booster up to 3.6v w/ the VX 150FSB (DDR500) trying to push it.

Greetings!

The DFI engineering team in Taiwan has made further modifications to the 855GME-MGF BIOS to remove the minor bug in 533 FSB detection. The latest BIOS is dated 2004/12/10 (file name “55GMDC10.zip”) and can be downloaded at http://www.dfi.com.tw/Upload/BIOS/55GMDC10.zip. You can also download the corresponding Diamond Flash Image (file name: “55GMDC10.exe”) at http://www.dfi.com.tw/Upload/BIOS/55GMDC10.exe.

Unlike the 12/06 BIOS, the latest one enables automatic and correct detection of 533 FSB in both BIOS and on the POST screen. By keeping J3 “ON” (default), the system will automatically detect the CPU clock (100 or 133 MHz) without the need to manipulate other BIOS settings.

It’s an important break through for us, and we are excited about being the only manufacturer offering this support! This latest BIOS is being validated and will be shipping BIOS in a week or so.

Best Regards,

DFI

The new bios is better for OC, picked up 2 seconds on super pi

Memory is at 222Mhz 2-2-2-5

Dothan AIR vs EE on cascade (exact same score)

I easily hurt someone for either of those AMD systems, hehehehe!

I'm not sure if they could do much better than that besides using an nForce3 250GB Ultra or etc..

Also keep in mind that Dothan is running with AGP 4X way less than half the bandwidth and yes, LESS MHz than the FX-55 and wayyyyyy less than the P4. It also sells for less than half the other two, what else is there to compare for games? This is at 2.53 533MHz FSB or about the same as a NW-B. I was just as impressed seeing the stock results.

Dewd, these little tiny coolers, 25W power draw under load (so they say), low latency, smart core and this thing rocks. Now it took me a while to get on the Dothan wagon but hey, I'm there. Just by costs alone, even if the Dothan was slightly slower, it makes it a much better deal than A64-FX or P4EE, as well as any processor from AMD or Intel that cost more than $400 or slower ones that cost more than $250. Why? They'd get blown away anyway.

Now, were these the absolute best scores for the Athlon64 FX-55? Maybe not, but were they they that far off?

So you find a better video card than the X800 Pro used and 1024 X 768 is a setting folks do use. Sure we know the value of removing the the Video card from the Equation but those are the only tests that shoulg be done.

I do have to add, yes, their memory scores do look like T-2 is being used instead of T-1. I do remember saying they had some problems with 1T memory settings in the BIOS.

Another reason Dothan is starting to look better.

AGP 4x vs. AGP 8x the difference is null...its like 1 or 2 percent at the most. So AGP 4x is not a vaild argueing point. but yeah this is nice...the price point is really nice for gamers...maybe my next system could be a Dothan or dual core thing...but who knows...Dothan doesn't seem like its ready for main stream yet, the board cost is really big :eek: But once its on a better chipset...like the 925XE or something...then the Dothan will be...HUGE :D AMD watch out

uhm, read that quote by Ed again but more closely this time ;)

But macci already checked that out and it's not so bad as Ed seems to think it is,.. not so bad at all ;p

compared to the previous bios revision by DFI or compared to the biosses found at X86-Secret?

Hey FUGGER or Macci,

What is the hole dia. for Dothan heatsink? Like if I wanna make a DI container for one...

Thanx :)

I posted some measurements in this thread a few pages back, 41mm between bolt holes and 6.6mm clearance from the closes cap.

That's really like 0 to 4% but that's nit picking! The point was, the bandwidth, memory and processor wise is less than half, even if the A64 system wasn't optimal.

Considering what A64 FX 55 and 53 costs, what P4EE and even the top two Prescotts, Dothan seems like a very nice option. You can use a smaller Power Supply, very Cheap slower RAM, Cheaper Smaller case, fewer fans and the whole thing would use less power and give off less heat. Please do some cost studies before you make those kinds of statements?

Craig Barret and his buddies might not listen, but you can bet your sweet bippy Paul Otellini will!

Ordering my dothan this week :)

It's going to go on my -47C phase rig

I'll have my CPU's later in the week, a 2.0 and a 1.7.....
One question, has anyone tried 1 x 256mB TCCD running @ 170fsb ( 283mHz)
This might pump up enough mem b/w to help a bit.
