Naaa.....TOO defficult....!!! :D
Most excellent stuff hipro5 :)
I might be playing one of these mobos tomorrow. Will most likely use my old trusty 1.6A for some high FSB testin. dont know if this mobo can actually beat my P4T533-C running at 180+ 4X RDRAM but in any case it should be an interestin mobo to play with :)
I have a 1.6a that does 2.72ghz on low end air with 1.72-1.75 volts. Wow do I wish I had a Prommy and a granite bay mobo to play with :(
Macci, what does your 1.6a do? I remember a while back you hit really high with your magic cpu.
DOes 3200MHz SuperPi stable aircooled w/ cold air Vcore 1.95V :)
3470MHz w/ R404 vaporphase cooling.
what's air temps?Quote:

i need it to compare with my 1600..
it can do 3200 stable (3dmark, spi and all) at 1.95v like yours, but with watercooling and 3° water, but think that temps under P4 are not so important... winbond HW monitor indicate aprox 24° idle if i remember right..
Air temp -6C
so our cpu seems to be similar, but i haven't any phase change cooling :( yet :pQuote:

wow, now i see, you are first!!! congrats macci!!! dry ice cooling for cpu&gpu??
hipro
are u still using d 2700 kingston? if ever how r u cooling it?
THanks bro :) yup dryice all over the place :D
anyway to do it on an AMD?
Thanks macci..... :toast:Quote:

It's a Very fast Mobo indeed......It is very stable and the Fastest Mobo I've worked with since the ASUS CUSL2-C for P3......You should try it .....RECOMENTED..... ;) :D
No ..... I'm with 2x 256Mb Kingson Value Rams DDR400(PC3200) with Winbond -5ns chips on board cooled by Thermaltake Cooper heatsinks......The PC2700 is on my ABIT Mobo now......I COULDN'T find another on of those to put them both on my ASUS GB Mobo.....SAD......Quote:

hipro5, have you tried PCMark mem bench yet?
You should be able to beat my score of 10289 ;)
With my Geforce4 440MX ritgh????......You're kiding.....!!!!
No way to reach 10000 with this VGA Card man......!!!!!.....Only 9600 somewhat...... :)
Hehhe well I 'only' ti4200 for that score =)
BUt yes your quite right.. just checked the orb and highest DDR score was like 9800 at 197FSB dualchannel w/ ASUS mobo + R9700
Don't forget AND the working frequency......cos PCMark Mem test counts down and the CPU's chase when it benchies.....So the higher the CPU, the higher the Membandwidth...... ;)Quote:

Hipro, what do you have at bit 0 in wpcredit for mem timing? (Ras precharche) With Kingston HyperX pc3500 I am only able to set it 1 (2 clocks) up to 174 fsb and remain stable.
All of 4,3,2,1,0 are set to 1.....Quote:

I'm a big newbee when it comes to ddr ram having been raised with Rimm but I figured out that I was able to have 4,3,2,1,0 to zero when I put 10,9 to 01 (timing at 6) This is still some 2 percent faster :)Quote:

Just did a 56.48 second pifast. I can go faster but I'd have to restart and up the vcore and fsb a notch. Don't want to when I'm having a good download with Kazaa now :)
Hipro5, which IC (in pic) on the board near or adjacent to the Dimm slots controls the Vdimm? I see two possible candidates.:)Quote:

hehehe I have been wating for this for the past 2 weeks :D
I hope he is writing it.:)
Now......Some shots.......I know I should take them BEFORE the Modding BUT I just didn't have a Digicam that day.....so here's the best I could do.......
Here is the location of the IC that controls the Vmem......
http://www.pctech.gr/hipro5/photos/ASUSP4G8X/Vmem1.jpg
EDIT : Vmem messure "spot".......
EDIT 2 : FIXED photos
We check out the PIN6 of this IC witch consists of 8 pins......Pin 1 is the one with the "dot" on the IC.....So from PIN6 we solder a resistor of 3.9KOhms to GROUND.......With this resistor we get : 2.5=2.96Vmem , 2.6=3.06Vmem , 2.7=3.16Vmem.......
IF we solder a 2.8KOhms resistor then we get : 2.5=3.1Vmem , 2.6=3.2Vmem , 2.7=3.3Vmem......
You can solder an SMD(Surface Mount)(tiny) resistor OR a resistor with 1% accuracy.....1/4 Watts........
We can messure the Vmem on the CHOKE(rounded coil) beside the Mem slots......
http://www.pctech.gr/hipro5/photos/ASUSP4G8X/Vmem2.jpg
EDIT: New photo with "spot"......
........and This is the Vagp Modd......We locate the SAME(number) IC BESIDE the AGP slot......AGAIN from PIN6 to GROUND we solder a resistor of 1.5KOhms 1% , 1/4Watts OR an SMD resistor(like the one in the photo)......With this we get : 1.5=1.7Vagp , 1.6=1.8Vagp , 1.7=1.9Vagp......
We can messure the VAgp at the CHOKE(ROUNDED COIL) behind this IC......
http://www.pctech.gr/hipro5/photos/ASUSP4G8X/Vagp.jpg
EDIT : New photo with "spot"......
Am I correct in seeing what you did here?? You didnt actually solder to the chip but somewhere near it with a Surface mount..??
Also, I am a little lost as to where you measure the Voltage at.. Can you be so kind and show me :D
Thanks!!!
See that copper coil? You measure the voltage there...Quote:

"We can messure the VAgp at the CHOKE(ROUNDED COIL) behind this IC......"
The Modds MUST be done WITHOUT any memory sticks and VGA Card onboard ........First we Modd , we messure and then we put the memory sticks and the VGA card onboard......Have luck and take a good care....... ;) :D
For the Vdimm, I see that you can use an SMD grabber to grab onto Pin#6 of the IC controller. Use a Variable resistor going to any ground on the case or m/b with a max of 10K or 4.7K if you are adventurous. The 10K (approx.) I found usually gives you 2.75V right from the start and then lowering the resistance it will increase the Vdimm up to the values Hipro5 says.
Ace-a-Rue,
Where are you measuring the Voltage at??? Kinda lost as to what Hipro5 said about where to measure.
EDIT::: I C where, but the prob is if I have the bord in my case... cant get to the backside.. have to think of a way... I got it. :D
I am getting the board today but if you start measuring each mosfet leg in the vicinity of the IC controller then you will probably find the output. Another way to measure is at the dimm slot but that is more complicated to get to the pin within the slot. Possibly this mosfet right adjacent to the IC controller can be maeasured 1st. If that isn't it, then start fanning out from there:
Beware of soldering a trimmer(varible resistance) cos IF it is set to about 0KOhs,you mitgh blow up something on the Mobo......You HAVE to be VERY carefull.........Now look at the "spot" on witch you can messure the Vmem.......
Absolutely agree Hipro5! Anyone using a variable resistor or POT should set it on max resistance. I have made a few "How To's" on Vdimm mods which explains in detail for a specific board but the procedures of setting up the pot or variable resistor are exactly the same and that is always have yourself set to begin with max resistance with a POT or variable resistor.
Ace-a-Rue,where might " that how" to be found? In the past I have soldered fixed resistors, but now I think I will use a vr with a grabber. Thanks
I've done two. Here is one for the Iwill P4R533-N and then for an AMD's MSI K7-D Master duallie board. The MSI m/b has a 8 pin IC and the 6th pin was the one that controlled the Vdimm on that MSI board. The Iwill had a larger IC to control the Vrimm, but it was the same one that was used on Abit's AMD board KR7A. So, some of these regulators are used on multiple boards.
The point here is the procedure to assemble the SMD grabber and attach either a variable resistor or miniature POT is the same.
I found 10K POT was the best resistance to start with. Usually 10K (set) gives you about 2.75v right out of the gate.

hipro5, what kind of speeds were you able to get out of it without any mods?
I just got the mobo and had the time to do some very quick tests. Ended up at 197-198MHz (PiFast stable) w/ slowest possible timings (my samsung2700 is the limiting factor there.. will be testin w/ some hyperX3500 soonish). Using single channel w/ XMS3500 I got it a bit over 200FSB (pifast 203 or 204).
Using the xms3500 / sammy 2700 combo in dualchannel mode I seemed to max out at 175MHz w/ (pretty) fast timings ( CAS2.5-2-2-7-0clocks-no Turbo = unbuffered 2040/2064).
w/ fast mem settings the performance is quite all right (not quite as good as RDRAM 4X though..).
Also seems that CAS and Tras timings wont make much of a difference. Slowing down RAS precharge and RAS to CAS seem to give bigger performance hit.
The maximum stable fsb frequency for me, seems to be between 197-198 fsb. I know that it`s not a maxxed-out processor issue, since I was able to hit the same fsb with a faulty promie installation, resulting in a +17 full load temp, with 1.675Vcore.
After a correct installation, i`m down to -12 full load.
The memory timings isn`t an issue as well, since with the buggy bios (slowest timings, no matter what you set in the bios) or with the tweaked bios, the stable fsb freq remain the same.
I NEVER test an unmodded Mobo to know how it acts.....When I get a Mobo in my hands , the first thing I'm doing is to Modd it.......Read below RootX's post. He is with an unmodded one......Quote:

Have you used WPCREDIT for the Memory timing?.....IF not then whatever you put in bios OVER about 143MHz fsb is useless cos the Mobo put them back at Cas 2.5-3-3-7......You can flash the Modded bios as well not to involve with the WPCREDID ......Quote:

Pretty nice band of numbers you posted there Hipro5.....:)
Here is a simple look at the IC Vdimm regulator and my way to measure the Vdimm. I used a Radio Shack 10K miniature POT(set to max 10K). With the Vdimm set to 2.5 in the bios I get about 2.70-2.72. Then I use the bios to adjust the Vdimm upwards to a max for me of 2.94v. Now, I can go higher but then I have to adjust the POT to a lower resistance to raise the Vdimm above the 2.94.
I use the bios settings in conjunction with the 10K attached pot if the SMD grabber becomes disconnected. At least I will have some higher Vdimm than just 2.5v. Actually, my board was overvolting in the Vdimm by about 0.078.
Is the SMD grabber with the tape on it measuring the V-dimm volts?Quote:

Yes, sorry for not making that clear....Quote:

Are you turning the 10k vr down to about 3.9k to achieve these voltages ?
No, he means it the way he said it! I have mine done the same way. With the 10k ohm resistor set all the way to 10k I get the same three readings - 2.73@2.5 and2.93@2.7.
Right on track sadcat!:) My 2.83v Vdimm reading on the DMM is with 2.6 set in the bios.Quote:

hipro, yes I'm using the modded bios and also using wpcredit&setfsb for testin max stable FSB for each mem setting.
But gotta do some more testin and mods once I get back home again..
Lo Fellas.
I´ve been thinking of getting one of these puppys..my self.
When I first read about the 7205 chip...people seemed to hav problem getting system busses over 170:ish. But lately I see more and more getting this high fsb/system busses.
My question is is there any need to mod the chipset volt to gain higher clocks VDD. Or do you guys just vdimm modd...??
And also about this modded bios....where can I get it...and in quick words... witch moddz are done to it..??
You noticed that Hipro5 has added those extra caps below the board to remove the rippling effect from the Vcore. I can't understand why Asus uses a two phase Vcore regulation even though they use large caps. I am fortunate that my 2.26 is a good cpu for o/c'ng. On my Iwill P4HT, 170 was max safe speed. On this board, it is about 178 is the top end safe speed. Although, I should say it won't stay with Prime 95 for very long (about an hour+) with the Vcore drop and ripple effect. Did I say Vcore drop?! Yes!:D I see via the PC Probe the Vcore going from 1.88V (at start of Prime 95) down to 1.78-1.79 with some momentary drops down to 1.74-1.76. I have the polling occuring at 1 second intervals. That really bugs me! I can understand a small drop and very small fluctuations but not at the degree I am getting....
UPDATED INFO.....
Now I'm with a Pentium4 3.06GHz........Guess what.......Not bad been at the SECOND place of PCMark Data base???......The first two DON'T count cos they are fake.....Now the FIRST one that counts is with LN2 and I'm SECOND(for the time been).......
PCMark2002 Compare....
That is pretty good Hipro5....you are very close to my 177 fsb. LOL!!:D
Hipro, I'd say that you've got the highest legit score there :)
P4PE at 193FSB would never produce such a huge mem result.
Thank you guys....I'm trying hard...... :D :toast:
hmmmmmm now why can't Asus provide >2.7v by default :(
here's my stock P4G8X with 2048MB@177mhz 2-2-2-6

http://eva2k.cjb.net/fileshosts/p4g8...-2T-unbuff.jpg
They need to release a bios of something for those of us that cant mod.
Does anybody know what PLL the p4g8x uses? And if there is a program that supports that to set the fsb from within Windows?
Btw, perhaps general knowledge but I say it anyway, here you can download a bios that does allow mem timings to be altered at high fsb and to keep those settings.

I don't mind the bold. It's easy to find his posts that way ;)
I am sure Asus probably said most users will use PC3200/DDR400 memory with the board and that should work at default Vdimm up to ddr400 if it is any good. So why provide anything more than 2.7v since this is a DDR266 board and 6 layers of PCB? I am at DDR350 (177 fsb) and I am using Twinmos PC3200. 2.7v should hold it ok but like you, I would feel a little more comfortable if I had ability to set 2.8-2.9. I want Vdimm to at least 2.9v on every P4 board. I've seen 1st hand like yourself as you climb the fsb and ddr ratio ladder you'll need punch thru Vdimm (& Vcore) to keep everything working at optimum.Quote:

If ASUS could give MORE Vmem,then the most of us wouldn't involve ourselves of modding it.....You see,IF the Mobo had 3Vmem on it's own , then we could "run" our memory sticks with more agreesive timmings than we can without modding it.........Quote:
