Pentium M on your Socket 478 platform

Post by Apoptosis » Thu Mar 17, 2005 11:47 am

The ASUS CT-479 CPU Upgrade Kit is a newly launched solution that brings the quiet and cool performance of the Intel Pentium M Socket 479 notebook processor onto ASUS’ Socket 478 desktop motherboards. Unlike other manufacturers that incorporated the Socket 479 directly onto the motherboards, ASUS motherboards combined with the CT-479 offer greater flexibility, allowing users to support both the 478 and 479 processors, including the latest 533MHz FSB Dothan platforms, on one single motherboard.

The CT-479 seen above actually has a quite a bit more to it than one might expect. Since the adapter will not allow a standard socket 478 heat sink to be used ASUS provides one with the kit. The blue jumpers are to adjust the FSB (front-side-bus) for CPU support. Depending on which Pentium M is purchased, users can select bus frequency of 533MHz or 400MHz via the jumpers. Also of special note is the power header for the heat sink fan that draws off the socket.

That is definately, by far, one of the best/coolest things I have seen; I cannot wait for the full review!!!! =P~

Its just too bad that Dothans are so expensive :(

price cuts were mentioned on page 2 in the article. July is the month and the price cuts are pretty big. This is after the dual core launch though, so most attention will be on DC.

yeah, last I heard was almost a 50% cut on the more expensive models.....very nice, Intel is trying to make them more competitive with AMD's offerings

Me too also. I'm looking forward to a full review. Intel is trying to stay up there with AMD.
Does life get any better then this!!

From that looks like they are winning, my amd at 2.6ghz does 1m superpi in 33 sec, so the p-m is beating my by 2 secs at the same speed thats an impresive amount when it comes to superpi.

i wander how much a dual cpu rig will cost (not the fastest cpu, simple workstation class MB)?

since the days of pentiumII this is a vaible _home_ dual cpu (heat, power consamption, NOISE!!! ) :? :shock:

Guess what I just got today! It's on the test bench now.

So far so good I have all the "default" testing done and have started to overclock the processor/board. I first tried to O/C with the defualt overclocking options found in the BIOS. They are 5%, 10%, 20%, 30% overclock options. When I try 30% the system fails to post, but 20% works just fine.

Here is a link with the CPU-Z shot:
http://valid.x86-secret.com/show_oc?id=8001

Running Dual Channel PC-3200 2-2-2-5 memory and a FSB of 160MHz x 16 for just shy of 2.6GHz. At these settings Super Pi 1 Million score is 29 seconds.

Here is a screen shot --

Update:

Got it up to 165FSB with no extra voltage on the CPU:

Now benchies on Super Pi 1 million are at 28 seconds!

Sweet dude!!
What are the temps like with that HS/F? Are you using the stock thermal pad on the HS or Arctic Silver? Is the fan loud? How far do you think you can get the fsb on a low multiplier?

Expect the full article tomorrow!! Due to all the hits and e-mails this article got I'm pulling an all nighter to get some real numbers for our readers.

Sadly I can't adjust the CPU voltage or the Multiplier via the BIOS as the options are not available. On my 2.13GHz Dothan I'm stuck at x16 and 1.36Volts.

Wow, way to get 'er done! LOL

That sucks you can't change voltage or multi! Thats half the advantage of being able to put it on a desktop board!!! I guess dual channel RAM is nice too though :(

Part 2 is being updated... ASUS-USA sent me over a new BETA BIOS that is awesome. Fixes the performance issues and the voltage issues that were noted in the article... Take a look at the new voltages...

Performance on DOOM 3 went from 54FPS to 120FPS on the 5900XT!!!!

Wow, that will definately be an interesting update! Excelent article!

Anandtech.com also wrote a similar bit on this Asus Pentium M adapter...

Looks like you got better overclocking results though! \:D/
