I'm running two duals. Two S2460's with 256MB each.

For those of you running duals....what mobo's are you running and what OS on them?

I like the MP boards vs the MPX boards because the MP's see XP's as MP proc's :jester:

My MPX sees dual 1.0GHz Durons as Duron MPs - how 'bout them apples :p

Now, if i can figure out a way to run them at 133FSB...muwhahahaha :cheers:

Ok, I'm sorry to be slow here but I'm new to the board
and I don't know anything about duals...

But

You are saying that an MPX board populated with two regular
1.0 ghz Durons would act as if the procs were MP procs?

Right? Right?

JPS

My Tyan Tiger MPX ID my 1.0GHz Durons as Duron MPs. AN artifect of the identifier strings AFAIK. However, they do run in full SMP mode - gotta love the cheap SMP!

I'm running dual celeron 366s at 466 (they run at 550 but not the DF client) on an Abit BP6 board. i dunno if i would recommend the board though, it's a bit flaky, especially the DMA (which isnt so bad if all you run is DF and have enough memory that the files can be cached)

2) what mainboard is good for dule xp's ??

3) is there a dule main bourd out for the slot a chips ??

1) wrong - just look at the messages here
2) None really, yet, but, there are some that work
3) Not that I know of.

There is a current discussion going on about Duals and the quirkiness of all dual amd motherboards atm.
Just follow this link

To answer question #2 -

I use Tyan S2460's. Don't overclock but they are dead stable and will take any kind of Duron, Athlon or XP and use as dual as long as both chips have same stepping, etc.

Well, I have three duals:

Abit VP6, PIII 700@933Mhz, 512Mb, with Raid0 on onboard HPT370- capacitors went bad after 13 months of crunching G@H, but I got a new one from the store :)

Abit VP6, PIII 700Mhz, 512 MB Ram, ++, run nicely:)

Tyan Tiger 2466, AMD XP1800, 512 Mb Micron Ram (unregistered), DVD- player, CD- burner, Hercules Fortissimo II soundcard, stable, fast and hot:D

Looking to build another dual AMD and sell 2 single AMD Tbird 1,4, maybe I'll use the MSI motherboard and MP processors, (you have to mod the new XP's to run them as duals).

How hot is *hot* with your XP1800s. I am assuming you are running two of them together. I ams asking b/c I am thinking about switching from two 1.0GHz Durons to a pair of XP1500s or 1600s on my Tyan Tiger MPX mobo. But, heat is definitely a concern for me as my case is somewhat smallish - Antec SX600...

ulv
06-18-2002, 03:21 PM
Well, full load running DF on both processors, hot is CPU0: 51C, CPU1: 57C, room temperature 24C (it's quite warm in Norway now), heatsinks: Thermaltake Silent Viking, full tower Adtronics with 120 mm fan (7 v) sucking air in front, PSU: Enermax 431 W.

I went for silence instead of an airplane, but it's very stable, never had any trouble. The temp difference between the CPU's are normal.

I have a Tigger MPX running an XP1800+ and an MP1900+ processor.

Now the question is with both CPUs running at different clock speed, will the overhead for Distributed Computing projects such as SETI or Distributed Folding be higher when using two clients compared to just using the same set of CPUs? I noticed that after running for weeks, the time taken for one client to finish faster and use less CPU time (Taskmanager) get wider between the clients. Will this cost a higher overhead?

Also, I am thinking of building another dual rig just to crunch something. Now since there are plenty MPX mobos around, is it more cost efficient to just get the old MP chipset Tigger or a new MPX chipset mobo (Tiger, MSI, Gigabyte)?

I have two Tyan S2460 Dual motherboards now. :D

1st) Dual XP1900s
256mb Crucial ECC Registered 2100 DDR
Adaptec 3950U2B 64bit Dual channel PCI SCSI card

2nd) Dual XP 1900s
256mb Kingston True value PC2100 DDR
EIDE - 40GB Maxtor and CD-ROM

Both dedicated crunchers running Mandrake 8.2

no problems . I bought the 1st one 4 weeks ago, the new one is only a week old. :D

BIOS is 'stupid' when it comes to boot up order with the SCSI box.

I see where people have used the Tyan Tiger S2466N with Durons, has any one tried it with the S2466N-4M? I don't know if there were any other signifigant changes besides fixing the usb. Anyone tried this and met with success? I am itching to get a dual board and don't have the patience to wait until I have the money for the board and the MP 2000+'s. :D

Well, I guess it's time to build another dual. I really liked the MSI K7D-L and ordered another one, with XP1800's. I might watercool it in a Yeong Yang server cube. Should be ready for crunching in a couple of days.......:D

ulv,

do you have to fiddle the bridge with that mobo?

and does it use regular DDR?

ulv
08-20-2002, 01:53 PM
Chinasaur: yes, I did close the L5 bridge on these XP's...... and it worked, show up as MP (very easy).
Memory: I bought Samsung 2700 DDR- unregistered for the other MSI K7D, but it didn't work stable, so I switched with the unregistered Micron 2100 that I used on my Tyan 2466, now both work like they should:)

On the one I built today I went for Crucial registered. Just installed W2K, all is good so far.........

Chinasaur
08-20-2002, 09:40 PM
ulv,

Can you post a URL for the L5 bridge fix? with pictures?

Looks like the Tyan Tiger S2466 is the way to go with XP chips and non-reg RAM.

Chinasaur,

Paratima beat me to it, but HWZone was down for me too, so I just took it from memory (brain not RAM) and closed the L5 at the end with a conductive pen (taped around). But MP's are getting cheaper and are totally unlocked, and the MSI board has multiplier adjustment (though I don't know if it works) as well as FSB adjustment if you want to overclock a lower rated MP.

I wouldn't conclude that the Tyan accepts unregistered RAM better than the MSI based on my experiences with two brands of unregistered memory;)

IronBits - did you get that board from NewEgg? If you did, I have a question for you. Do they pay for shipping back for the RMA'd parts? I've had to RMA a board 2x myself, and it's getting a bit expensive to ship it back each time.

I agree, the S2460 is only rated to take MP1900's because the higher clocked AMD's pull too much current through the ATX connector. These then heat up and melt. The S2466 may be a little more expensive but can handle all current and future CPU's up to and including the Barton core.

So I could use the XP rather than MP processors.
and cause I'm cheap ;)
I would have taken a refund, but, the RMA policy is such that I can only get a replacement :(

IB,

you know that you can use XP's on Tyan 2466, MSI K7D-L, I do, though you have to connect one L5 bridge (it's very easy 'cause it's on the end) on the newer XP's;)

As Phil points out, you should watch the 5 volt, some boards have melted in the ATX connector on the 2460 (has no extra 4 pin connector):scared:

Hope you get a nice board this time:D

I requested a refund, and it was granted, with a $25 stocking fee. (they have to recover all those shipping costs).
I picked up a ASUS A7M266-D board.

The Iwill's rock (I have 2)...they even run the Barton's with ease. Check my latest adventures in getting 2x XP2500's running here (http://www.thegenomecollective.com/forum/showthread.php?s=&threadid=5473). I also have 2x XP2400's that run fine aircooled at 155fsb (2325MHz) on the MPX2 (here (http://www.thegenomecollective.com/forum/showthread.php?s=&threadid=4633)). The MPX2 has the best power distribution of any dual AMD board which gives superb stability and also gives it the juice needed to hit sky high fsb's (I know a few people running over 170fsb :eek: ). For your system, I'd grab an Antec TruPower 480W...they are quiet and provide the necessary juice to run 2x XP2400's. You won't be dissapointed with this setup.

LOL, I know it sounds mad but it works so much better. There are other methods of cutting the bridges...a friend of mine used a scalpel blade. The problem with these methods is they leave cuts between the bridges which make them very difficult to rejoin again. When using an electrical current (a 6v lantern battery would suffice), the bridge is "blown" below the surface of the cpu, leaving a nice flat upper surface to join the bridges again if needed. This was useful to me as I could explore the CPU's limits with a high multiplier and low fsb and then change the default multiplier again to hit the CPU's limits at a higher fsb.

The Iwill MPX2 has support for EPS12V and ATX12V PSU's. If your PSU is either of those standards, it will work fine. If it is a regular ATX model, I'd suggest replacing it.

Would not boot as dual. So I made them 2400+, and put them in the Iwill MPX2, and now they are crunching DF:D

I also broke my left thumb a week ago..... and being lefthanded, this mod was scary:scared:
