wont high pci-e clock mess with the controller? or does it have an indipendant clock like the pci cards?

Stick to your old controller if your not going to use it as a RAID controller for more the two disks. Running RAID easily maxes out the bandwith usage on the PCI bus.

132MB/s is the theorethical limit of 32bit PCI running at 33MHz.
250MB/s up and 250MB/s down are the theorethical limits of PCI-E 1x at 100MHz

Yeah was looking at the specs of your RAM, hmm may try and get hold of some TCCD or something thats good at high FSB, see if I can beat my 24 sec at superPi :D

I know it's a very old quote to bring up.. but I'm inclined to do the mod. In k|ngp|n's pic I can clearly see the VR, but kiwi's quote confused me. No... I don't see the 10k in that picture. :( ... I see the wire soldered to the second leg from the top on the left side of the chip.. (like k|ngp|n said) but I see no VR. For all those reading this is my first crack at a volt mod, so if possible please keep it in mind before replying. *deep breath* might also mention that I have no clue how the resistor is meant to be soldered... :wasntme:
Sooo. Yeh... little help.

Worth mentioning... ( I've done electronics - very basic. But i've never soldered a pot to anything at just one point usually it goes in one leg and comes out another. So I'm confused as to how it works (considering I only see one wire).

BTW k|ngp|n just wondering what FSB's did you get on your chips before you did this mod? (or anyone else for that matter).

Don't worry BlueWonder its all good. You are right there is no VR in the shot, the grey wire will have the VR connected to it. This wire represents one end of the circuit, usually with these vmods its shown with just the one wire because the other end is connected to ground, tho this may not always be the case. Simply solder the wire as shown, the nto on leg of the VR (remember to set it to max resistivity) the nsolder the other leg to a grounding spot like the motherboard mount etc. I prefer to use the ground on the IC itself and localise the VR but this is not always suitable, esp wit this one as the PCI-E graphics cooler will be in your way. Hope this helps you out.

It's DONE!! :D

It's done. :D And works a treat may I add. Thanx Johnny for the advice. I can breeze to 250 now with ease. Included pics - I used the "Chassis Fan" grounding pin as the grounding point. As this is my 24/7 rig I think it's convieniant being able to plug-in and unplug the mod.

Things I found along the way:

Must boot at 170 FSB or higher for big FSBs. - k|ngp|ns quote on the first page is the best thing since the invention of the printing press. - Without following it you'll be hard pressed to even reach 200fsb. It's silly, but it's true.

I was able to run the board stable with bh5 as tight as it can go up to 275+ without having to adjust fsb term voltage. Haven't needed to mess with that setting yet.
Chipset mod is an absolute must. If you check with a dmm, you will find that chip voltage is set alot lower than setting in bios. On my p4gd1 I have here, if I use the 1.6v setting in bios..and check with a dmm at appropriate mosfet location, the chip volts would read 1.4x volts. Vcore mod is easy and a must. There is a vdd mod, but I just use my trusty booster as it works perfectly up to 3.6v actual. I see alot of guys having difficulties getting high fsb with this mobo. The trick is to boot at a certain fsb and have pci-e set properly. Then when you get into windows, you can hit your target fsb using clockgen.
For example, with 780m and target fsb of 272 in windows for benching this is what i do:
I set fsb in bios to 170-175(actual number depends on what you target fsb in windows will be) and set pci-e to 120-125(again, number depends on what your "target" fsb in windows will be).
Ok, so I boot at 175fsb, 125 pci-e, and give chipset 1.85v. When I get into
windows, I can now use cpuid and clockgen to adjust my multiplier to 14x and then crank the fsb using clockgen.
If you do not do it like I described, you get hardlocks in windows as soon as you set highe fsb with clockgen. Ignore the pci-e freq reading in clockgen as it is wrong.

I think this should halp about 99.9% of you that are having problems getting high fsb. I will think of some other stuff in abit...

If using 50K resistor don't freak when you find max resistance gives you a VDD of 1.64 (which was my boards normal Chipset voltage) just turn down the resistance until you notice the volts starting to rise. - It may take a fair few turns. And don't assume each turn will give you roughly the same rise or decline in volts... when aiming for higher volts whilst already having it set to a high VDD (say 1.7) it tends to take less fractions of a turn to go higher (trust me - I am currently endebted to the failsafe mechanisms put in place on this board.). - CONSTANT MEASURING WHILST ADJUSTING IS REQUIRED.

For all those with 780's - I've gotta give the CPU 1.6Volts in BIOS (which is more like 1.65) @ minimum to start at an FSB of 170+. (I'm assuming because of resulting clock speed on the 780 (which has a multi of x17) - which isn't such a bad thing seeing as I'm sure you'll be booting at that speed specifically to give it a benching run anyway.)

Multimeter is a must.

Success . . . or at least a partial win for me

Back on Page 4 and 9 I've asked a few noob questions (ok alot) while trying to strike it on my own, overclocking (for the first time) my machine. Just a quick question I know borderline for a northwood you want only 1.7-1.75 cpu core as an absolute max. I've set mine in the bios for 1.6500 and would like to turn it up a bit to see if I can get a few more mhz. When I check the hardware monitor in the bios it reads something like 1.61-1.68. A little bit of drift. When i check my everest program it reports a scary 1.74-1.75. Holy crap, am I burning out my chip as I speak? Which reading should I trust? (No I don't have a mulitmeter much less where to take the readings). Any help?

Last success overclock:
CPU: 3400.57 (from 3010.20)
FSB: 226.70
RAM: 226.70
PCIE: 105.07
PCI: 33.34

what is the resistance you end at for the 1.7? i may want to use a 10k vr to have more turns per volt. also i boot at 168 fsb with a 780, no mods yet with 1.34 in bios vcore. i end up with 1.45 or so and have no problems. so far i have seen 268 fsb.

Yeh, I've found that I can boot @ 168 and get high FSB as well, I think it's really anything above that 166 wall. I wouldn't beable to tell you what resistance you need for 1.7 my chip is automatically set there when I choose 1.6 but yeh, I'd probably go for a 20kvr if I was to do it a second time around.

Well I still have my p4gd1 and unlike some people really appreciate you guys getting it for me. I got an antec 500w 24pin power supply to replace my antec 550w 20 pin psu. I see no difference at all with using the 24pin psu. I think that I will go back to the 20 pin psu so that I can use my ocz ddr booster. If I use this booster it is the same as doing the ddr mod. I really do not want to mod this board as they are impossible to get. I also have a p4gpl-x that my friend stryg from XS got for me. Maybe I will mod one of them.
As for memory I just got a refurbished Crucial Ballistix 2X1GB kit from New Egg for $221 shipped. Looks like somebodys rma is my gain as they overclock so far 251fsb 2.5-2-2-5 2.8volts. They overclock just like the 2x512 kit I have. I have been trying to run a multiplier of 10 and get 260+ but my system freezes. Guess I will need mods to go higher. I can only get 115pcie.

Maybe you already have discussed that problem here, but what`s wrong with the P4GPL-X voltages? If i raise voltages in bios, it still will be default. Some other guys have same problem.

i was thinking earlier today and decided to use eist to drop my multi to 10 to find the max fsb, after reading about how some multipliers dont completely work. 10 worked like a charm and let me get to 245 or so, then it crashed. Much higher than the 231 that clockgen normally crashes the machine at. I restarted and went to bios to up the vcore and increase pcie speed a bit more. rebooted and... nothing. turned off and turned back on, went into bios, set my normal 24/7 settings and.... nothing. i thought something might have been corrutped, so i booted with the bios defaults to re-flash the 1006 bios. rebooted again, tried my normal settings and... nothing again!. I reset the bios and tried it again, nothing again. I started getting really pissed off and booted with the bios defaults, got the latest version of asus update and flashed the bios to 1005. my 24/7 stable settings were not booting. I investigated a little more, using all of my settings and just slowly increasing fsb. It crashed in bios at 160 and wouldnt boot at 167+.

I don't see how this could happen, my 24/7 settings were rock stable, how could the fsb suddenly drop like that? Between this and not being able to run 1:1 with 4 sticks, and the irratiting fsb limit, this board is driving me nuts

I'm going to fire off an email to asus now

oh, and all the ram works, cpuz wasnt running

I responded with this --->

To get it solid like rock over 166FSB I pump the CPU vcore to 1.6 and give it a bit of usage shutdown and then set it to a volt that suits the clock speed. It shouldn't pain your cpu to much once the intel speed step in windows kicks in (if you have it enabled). but it's only for a short time anywayz.
Anywayz, don't get to frustated mate, learn the ways of the forc.. err, board and everything should pan out a-ok.

Now I still stand by the quote and it's probably a good one to have in the torture chamber (which seems to have slackened off recently) but earlier this week during a bench session a came across a strange happening...
My board was as stable as granit when it was time for the 24/7 settings. No need for the overvolt. Nor the painstaking 15min fluster. It just switched back straight away.. and whats more, with an even lower vcore than before. I'm currently running the beast @ 2.79GHZ with a vcore of approx 1.44-1.45 (1.4 in the BIOS) where as before I pumped that thing upto 1.5 real volts to achieve the same speed. The difference?

I enabled the ACPI 2.0 Support in the power menu... Yep.. that's it. No terribly big revelation but more an incredible oversight. So /rantoff and give it a go. I apoligise if it provide no stability increase for the rest of you but it's definatley worth a mention as it's been the bane of every OC'ing session I've had with this board.

Peace out!

Great info man, thanks ;)

But I have a question. Is there any one here willing to completely hipromod my C479 adapter + P4GPL-X in europe? I figured this is the best place to ask. Just shoot me a PM.

Hey Winterwind.
I purchased that auction on Ebay. I'm pretty psyched for it to arrive. I sent you a PM also, but in case you hadn't seen it, I wanted to ask you if there are any special considerations to safely using this volt modded board? For instance, are there any adjustments to be made to the pots, or is everything still handled in the BIOS? Dumb little considerations like this keep me up at night, worried that I might accidentally fry my peripherals if everything isn't set correctly.
I have a P4 Northwood I'm going to use until I can afford a Dothan. Please PM me and we can discuss it further without taking up this thread.
I'd appreciate any info you could give me.
Thanks very much

Which voltage do I trust?

Not sure if anybody has answered this already. ( I tried scanning the many pages on this thread but found none)

Which core voltage reading should I be trusting? My everest program is reading a higher reading while my bios is reading something smaller? I set to 1.65v (bios is reading with a little bit of drift) and everest is reading 1.75v. I'm a little scared cuz northies tend to fry at 1.8v. Any ideas?
03-02-2006, 09:59 AM
sky

easiest way to find out is grab a mulitmeter and have a go at it. both values are
probably off, though the boards (p4gd1) do overvolt a bit - unlike the other asus
p4 boards that seem to undervolt somewhat.
the bios value +.1v should be where your actual vcore is at - if you're using a
p4gd1 that is. so everest may be close - but you'll never be certain, if you don't
measure it yourself on the board.
places where to check the voltages have been posted a while ago.

Stupid Question about FSB speed

Hi, everyone.
I might get flamed for this so please forgive my ignorance.

I've been used to the default fsb speed to be 200MHz for my old motherboard, and it was my understanding that was the standard speed for ddr. I would overclock my Mushkin BH-5 sticks from there. Yet for some reason I keep seeing people referring to fsb speeds of 165 or 170 etc... Am I missing something? Why so slow? Wouldn't that be a setback? I thought that the bare minimum I'd see from a stock P4GD1 would be 200MHz fsb and any overclocked boards would be higher than that.

Could someone please explain this to me? I'm befuddled.

Thanks,
Erik.

Hey thats why we post, to learn :toast:

The reason everyone seems to be referring to 167MHz is because setting the FSB equal or higher to this enables the PCI-E/PCI locks so when you do increase the FSB ( with say clockgen) the PCI-E/PCI frequencies stay the same. Please note however that there is a "limit" to how high you can increase the FSB. THE general rule of thumb is that your PCI-E frequency * 2.2 = the maximum theoretical FSB you can attain. Please refer to the very first post for more details in this matter.
