has anyone done the L12 mod on the ultra B?

What infinity (not lanparty) should i look for?
Is there a rev B of the infinities, or only the A?
If both exist, please tell me which one to get then :)
PS. Where would be best place to get them in europe?
I know some of these questions have already been asked in here, but after like 30mins searching i got tired of it :s
After all, it takes you guys like 2 mins time to help me out here and i would really appreciate it... :)
Thx ;)
Theres only one version of the Infinity so you can't go wrong, where in europe are you ?
TDF.

The Anomaly: nVIDIA’s nForce2 and tRAS
An anomaly can be described as something that’s difficult to classify; a deviation from the norm or common form. This is exactly the situation with tRAS (Active to Precharge) and nVIDIA’s nforce2 chipset. As said before, not sparing the effort is what has lead to the initial discovery of this anomaly many months ago. It’s pretty well known by now, in a nutshell, a higher tRAS (i.e. higher than, say, the Mushkin mandated sum of CAS+tRCD+2) on nforce2 motherboards consistently shows slightly better results in several benchmarks and programs. In most cases, 11 seems to be the magic number. Other chipsets do not display this “deviation from the norm”, so what makes the nforce2 different?
This most interesting thread in our forums has been on the topic for a while now, and TheOtherDude has given a possible explanation for this anomaly.
“Unlike most modern chipsets, the Nforce2 doesn't seem to make internal adjustments when you change the tRAS setting in the BIOS. These "internal" (not really sure if that’s the right word) settings seem to include Bank Interleave, Burst Rate and maybe even Auto-precharge. For optimal performance, tRAS (as measured in clock cycles) should equal the sum of burst length, plus the finite time it takes the RAM to conduct a number of clock independent operations involved with closing a bank (~40 ns) minus one clock if Auto-precharge is enabled (this factor can be slightly effected by CAS, but should not play a role in optimal tRAS). To complicate things even more, one bank cannot precharge a row while the other specifies a column. This brings tRCD into the mix.
Higher isn't always better, but the reason everything is so weird with tRAS and the Nforce2 is simply because the chipset doesn't make the internal optimizations to accommodate your inputted tRAS value like most other chipsets.”
Thanks :up:
ok guys, I couldn't resist and got one :D Sold my NF7-S and some 256MB Twinmos. Got some BH-5 and an Infinity back. Heres what happened:
http://www.fewture.cistron.nl/265MHzsandra.JPG
Vcore: 2.00V (1.95 real)
Vdimm: 3.65V
Vdd: 1.9V
Bios: 1-31 beta
MP x FSB: 9,5 x 265.8MHz
Timings: 11-2-2-2-2
CPU int: Agressive
I'm stuck now.. I think Vdd, but no mod :D Nice board! :banana:
In 3D I went up to 255 and havent tried higher yet:

Nice :toast:
Try out a few of the other BIOSes.
Will do that. So far I ran 11-27 and 1-31. I think both do about the same here, but can't say for sure. I only have the the board 2 days now.Quote:

Right now I'm having problems priming with BH-5. When I just switch the ram with my CH-5 it does prime no problem. Putt BH-5 back and fails at test 1 :( I disabled command per clock now and it seems to work. Wasn't that only for doublesided? I'm using Twinmos BH-5..that's singlesided right? Could use some help here..little confused.
In sandra I cant go any higher now. First I lose my mouse and then it reboots. I will have to test on 1.8V Vdd to see what happens and figure out what is holding me back now.
So far the board is nice, but the CPU clocks suck big time. Vcore fluctuating like mad and lost about 50Mhz vs my NF7-S (on same Vcore). To let my CPU fly I need volts :D More than 2.2V and that's not gonna happen on this board..
But 260MHz pifast is insane imo :toast: Very nice.
Here are my screens:

TDF.
good board. working with it when i get free time
Does the L12 mode ( to default XP processor to 166 FSB) work on this mobo...?????????????????????
Errr there's no need to do this.
Nice sig pic, mata :D
Where did you get this "smoking" pic???
now reached 253 1:1 with my mate's BH-5
3d only up to 237 tho :(
higher stable fsb with 133 processors. my 1800+ has trouble getting past 190 when it really shouldnt. but does anyone know if it would work?Quote:

Both a 1700+ DLT and a barton-core Mobile 2400+ do 250+ FSB (10 mult) without issue on my Infinity. Others are doing better than that.
So, is the L12 mod necessary on these boards? I think not :)
You have NF7 ? :rolleyes:Quote:

Got a 3D Mark run at those settings SAI?
can someone tell me what pins do i need to check on the mosfets to read my voltage readings from a DMM
i think my LPB has voltage issues
the L12 mod does nothing for bartons.. but.. maybe thats why i cant hold 260fsb?
its worth a shot. what must i do to mod it on a mobile barton?
Tooo expensive :'(

Good job. :thumbsup: Funny, the 4MHz FSB thingy, eh??? ;)
But try to push the graphics card... the system will get more voltage dips (getting unstable) because of the v-regulation and I think it's harder to complete a bench ;)
Or did you even fight for this bench to complete? Restarting it again and again after being dropped back to desktop one more time... :rolleyes:
My bench was done directly after a restart and completed perfectly :) And me thumb idiot thought I could get it stable :rolleyes:
