"Asus nFORCE2 (thread retitled)"

[sysfailur]

Got it back up and running, here's @ 200mhz dual channel 2-2-5-2.

[Hallowed]

97% bus effeciency @ 200 FSB. That is crazy.

Even crazier that this thing had 1 GB of memory @ 207 FSB.

Keep the pics coming dood.

[sysfailur]

Here's a better one Not going higher till I get more voltage/better cooling on mosfets/etc.

[Bravo]

Memory timings? Voltage? Memory (what mem)?

Well there is no "1 or 2T" timings (the one we're familiar with on kt333/kt400 boards) so my timings were... cas2 522. 2.8v and 2 x 512mb XMS3500.

By the way guys... here's some lovely aircooled 2600+age. Heh... Wasn't stable, but did get into windows. Just needs more voltage and I bet 2.55, or 2.6 would be feasible aircooled. W/ better cooling ... I have a feeling this is a 3ghz chip This is 1.85v btw *tehehe*. Solid @ 2.4ghz (200x12) btw.

I found the data sheets for the controllers.

Looks like pin 9 of L6917BD for Vcore and pin 6 of 6520 for Vmem, unless we somehow trigger overcurrent, then it is a bit more complicated and I'll have to work around it.

So you need me to check the ohmage now? If so I can do that np.

Got it...

6917 chip - 1193 Ohm
6520 chip - 702 Ohm

Does that look right?

Looks reasonable. Now get yourself some VRs, set the one for Vcore to 25k, the one for Vmem to 15k, and get the ball rolling.

Instead of relying on an external clock, with an elaborate clock forwarding scheme and synchronization of data and strobe signals, Serial ATA is using an "embedded" clock meaning that the data themselves act as clock signal or rather as synchronizers for the internal receivers at both ends of the transmission. One potential problem with this scheme is that during periods of no data transfer, the system could get out of sync. This issue can be completely avoided by sending a dummy signal consisting of a regular IOIOIOI pattern. The result is a high speed interface with internal clocks at both ends that are synchronized by the data flow. Because there are no parallel paths, clock skew is simply impossible

Thats the explenation I was looking for. Becouse of that, if you use SATA drivers or SATA-PATA converter on the serial controller, you wont be affected by too high PCI BUS, meaning, PCI Divider becomes irrelevant (Except if you are using some special add-on card ! )

Hope this helps to persuade more people to use the nForce !

DJ_Datte:

Still, it affects more than HDD's.

Anything on the PCI bus gets worked, including onboard features stemming from southbridge, CDROMs, DVDROM, CD Burners, everything.

If the board truly has no 1/6, perhaps it has latency timers to help with the overload (remember the 8KHA+?).

Sys, you had your board up to 211 right?

I have a hard time believing a board with 1/5 would live @ 200 comfortably if you had an 800MB/s Northbridge to Southbridge link. Hell, the KT400 has a 533Vlink and it craps out at anything above 205, save Epox / Abit boards.

[Wolf]

Thats interesting I didn't know sata wasn't effected by pci speeds. What do you do about dvd players and cd burners? Is there enough serial ports to use all these devices on and can anything other than a hard drive be used on them?

[QuadDamage]

did you try these pots yet, Sys?

We need to have your title changed to "VOLTAGE MASTA". I will buy these tomorrow

211 in bios... it wouldn't go into windows. I think I just need more voltage in the DDR. We shall see after I mod it.

could you do a sandra bench at 9x201 just to compare against

this one which was done on my 8k3a using a single stick and only 256mb


oh and whats the time in super PI 1M with 200x12 , some 3dmark scores would be nice too

[sysfailur]

No, don't have em yet. Will get em tomorrow and hopefully do it tomorrow as well.

Btw, DDTUNG, my man, how much is this volt mod gonna let me go up to? I forgot to ask that in the previous post. Thank ya

Why couldn't the Epox 8K9A2+ be like this...

BTW DDTUNG... YOU RULE!!! Nice work.

I can't find super pi to download!!! I lost the copy on my hard drive, please link me!!

I don't have access to 201, but I can set it to 200. And if you wanna see that it's on page 2 Also, let's not forget that there may be some new drivers (hopefully like the det 40.xx jump) which may boost performance later down the road And I haven't done any WPCREDIT tweaks. The bandwidth thus far is looking fairly decent.

I cant bench more than 1800 on the cpu


and diferent Cpu mhz means a diferent sandra sp1 mem bench

thats why I asked for it

You should gain a few percent with these VR settings, but the voltages will go up when you adjust the resistances down, until you hit OCP(overcurrent protection).

Of course there's a small chance that I have the wrong chips altogether.

Heh well I'll turn a smidget, and if nothing happens then I'll just unsolder em.. no biggie.

Ahh ok. And thanks for the file! I will also run some unbuffered results. I'm not gonna be firing the comp up again though until I get the volt mod done

[fireandsmoke]

Sys,
Just curious, does your BIOS show accurate temps? I'm thinking my mobo has whacked out temp sensor and is triggering the new ASUS C.O.P. CPU overheat protection...
And where is the option to use dual channel ddr...I didn't see it in BIOS??? Or was that because I only had one stick in?
