5GHz

[lsevald]

Two pin modded XP-M2400+ 35W Bartons running at139x18 in an Asus A7M266-D dually board. It will run with some stability at 2x2.6GHz (Prime failed after 10hrs on CPU#1). Vcore is currently at 1.775V, so when I move it into a proper case (just testing it on my desk right now) with better cooling (two separate water loops) and up the Vcore a bit, it will probably run fine at 2x2.6 :cool:

Wow! Looks awesome! What kinda benchies do you get with that beast?:D

[lsevald]

I took these yesterday at 2x2.56 :) 3D is out of the question with only a GF2MX.

[edcentric]

And the memory scores won't be much, but damn, will it crunch numbers.
I would like to see that box folding Tinkers.

:eek2: :thumbsup:

[lsevald]

2x1445=~2890ppw (if based on p639 tinker performance)

[RWB]

Well I see no 5GHz, but that is a nice OC.

LOL...yes, the RAM performance sucks.

RWB:

2x2.5=5GHz does it not? ;) These chips run at 1.8GHz default.

2*2.5GHz = 2*2.5GHz.... it's like having 2 cars running at 50MPH, it's not the same as having one car running at 100MPH (or KPH if you prefer)

Depends if its folding or not ;D :fold: :fold: :fold: ;D

[deicist]

um.... I thought the only benefit of a dual processor rig in folding is that it can run 2 instances, one for each processor? In which case the car analogy is pretty much spot on :)

[edcentric]

No, try thinking of two dump trucks. You need to deliver a specific amount of material. Does is matter if you use one truck that makes the trip in 1/2 hr or two trucks that take 1 hr? No. When it comes to raw math power it is the same. Some software will run faster on a single 5GHz, but when you can run two threads or have a prog that runs true MP then the results are the same.

Wow NICE. Makes me want to get 2 for my MSI K7D-Master L. If I could get the right chips I would think I could do the same. FSB goes up to 150 as well.

[lsevald]

I got a K7D on the shelf here. Great board, but it does not like the mobile CPUs I'm afraid. Check out the SMP section over at ocforums, someone modded a BIOS which supposedly works with mobiles.

I also have three Asus boards (only two up atm), and once you master the quirks its a great board. It isn't as FSB friendly as the K7D or Iwill, but mine will do 145ish. I didn't have to mod any bridges on these 2400+ XP-M's. I just painted the backside ("pin mod") of the CPU's to 1.775V and 18x multi. Took me 45 minutes :)

[mmonnin]

Not even an SMP mod?

[lsevald]

No, I didn't have to cut any L5 bridges :)

[mmonnin]

WOW That is totally awesome!! Do you know of any others that can do that?

[lsevald]

Don't qoute me on it, but I believe the Gigabyte and Tyan 760MPX boards also accepts dual unmodded mobiles. I suggest you check out the mobo section over at 2cpu and the smp section at ocforums for more accurate info.

The Asus board is great...totally worth the 65 bucks I paid for each (refurbished). The only OC funtion that seems to work reliably is the FSB setting in BIOS though. Upping Vcore using the onboard jumpers can be risky as the board have a tendency to drop Vcore back to default on one of the cpu's from time to time (which obviously can cause havoc if you allow the board to boot...I lost a partion due to this once...and several WUs). But I have had no problems when pin modding the Vcore higher (I do both just to be sure). Also, theres no multiplier support in BIOS (this have no real value anyway, as these boards only supports 4bit FID->up to 12.5x). The standard Barton interactive pinmodding guide over at octools.de is all you need. The Asus board disregard the mobile specific L6 multi setting, so it's just as if it were plain AXP cpus.

The best part about this board is that it uses the 5V rail for one CPU, and 12V for the other. So the PSU requirements aren't as high as on other dually boards (more balanced load). I recommend mounting some heatsinks on the CPU power reg MOSFETs though, as these gets insanly hot when pushing the system this much out of spec.

[mmonnin]

Hmmm interesting!! Does it need the water? Its not that high of a voltage really. An ALX-800 and SLK-800a fit on the board but nothing bigger. The ALK-800s are like $10 too.

[lsevald]

For testing purposes I'm just running 2 small, really old (3 years old? targeted for the value segment) Swiftech MCW362 blocks with a single Eheim 1048 (using Y-splitters) and a BIX rad, so I doubt cooling performance is better than good modern air cooling. Heres a MBM high/low summery after running FAH for almost 5 days:

EDIT: BTW, the Asus board does not have the 4 holes around the socket. The ALX800 looks like a good choice if coupled with powerful fans.

I have a problem

Asus A7m266-d rev1.04 Bios 1011beta003
2 x XP-m 2600+
I have made these modifications
I use silver paint
The BIOS recognizes 2 CPU :
- CPU0 2400MHz -> 18*133 Vcc 1.775
- CPU1 2400MHz -> 18*133 Vcc 1.775
BIOS : control MP is OK!!!!!!

:mad: :mad: :mad:
The WindowsXP pro works alone with one CPU!
Only the SisoftSandra software in CPU information sees the second CPU.
All the benchmark use only one CPU

information WindowsXPpro :
Computer -> PC multiprocessor ACPI
CPU -> - AMD Athlon(TM) XP
- AMD Athlon(TM) XP

HELP HELP HELP

:D :D no problem :D :D

with BIOS 1011beta5, WindowsXP pro works with two CPU!
- CPU0 2400MHz -> 17*141 Vcc 1.7
- CPU1 2400MHz -> 17*141 Vcc 1.7

question:
asus a7m266-d & graphic card????
Geforce6800??
ati9800pro??
ati9800xt??

As far as I know, all 3 of those cards should work just fine in the Asus dually. The Nvidia card might be the better choice though as Nvidia cards generally tolerate an overclocked AGP bus much better than ATI cards. At least that's my experience.

EDIT: My A7M266-D has 2-XPM-2400's also, but it is only stable up to around 2200 MHz. It's all the luck of the draw on the procs. I also have no problems with getting both procs recognized using the 1011 beta5 bios.

[Thrax]

You're right, Mud. My suggestion would be the 6800.

thanks :)
I have decided:
I buy the geforce6800
thanks

[Jimborae]

Good choice, with any luck it'll softmod successfully, opening up the extra pipelines for more performance.
