Tell me what it says on the chips of the ram. I am using the UBER hacked bios, but, makes no diff I still can't get above 200. I have the ram at 2.8VQuote:

I have two and they are both single side, do you think a heat sink with fan would help now or after the chip set mod, thx:rolleyes:
Not the sticker info, there should be some printing on the actual chips, what does THAT say?Quote:

Ok, that is the good Winbond 5ns chips. This ram is rated at CL 2.5, but I run it at 4-2-2-2 at 200 FSB. Now, keep in mind that it should not be the ram holding back your FSB, it is something else, chipset voltage I suspect. I used the UBER bios but that still has not let me go past 200:mad: How high of a FSB were you able to go with your other ram?Quote:

If you are getting errors in memtest, there is a problem with the ram, especially at only 133! How many sticks do you have? If you have more than 1, test each stick seperately with memtest to see which one is the problem...Quote:

I am happy to report that my first vmod was a SUCCESS!!!
No pops or smoke when I turned it on!!! :D
Here is a pic:
http://www.savethru.com/vmod
Here is what I have my 1600+ upto so far using 2.0v:
http://www.savethru.com/OC%201861
My temps are still awesome 34 idle--38 load.
Man... The SLK-800 and 92mm Tornado is a great combo!:D
I tried to set the voltage over 2.0v without success.
I set it to 2.05, save changes and exit from the BIOS.
Then something weird happens.
The system will not display anything and some of my case fans stop working. My CPU fan still runs but my exhaust fans stop.
I have to pull the power plug, lower the resistor(voltage) and wait a few minutes for it to reset. Then I get video again.
Does this systemboard have some sort of OverVolt Protection?
Could it be something else causing this?
The reason why I did this volt mod was to get this 1600+ stable above 1800mhz. I was kinda hoping to hit 1.9ghz with the vmod but it looks very doubtful.
Maybe I should just fry this damn 1600+ and buy me a 1700+ Tbred 'B'. I heard they have been hitting 2.5ghz!!!
yes you are correct, whener you pass the limit your mobo will freeze, and if you restart while alittle over, you system will freeze and off and on again and it should work, but everytime it will need to be shut off and then on again, something like, but is better to find the sweet spot and you won't have any problems:DQuote:
Does this systemboard have some sort of OverVolt Protection?
Yeah...thats exactly what is happening.
What I did was adjust the volatge regulator higher with the system off. I know this sounds crazy but I did it in small increments. I got the system to boot at 2.05v but I can't reboot. It just craps out.
So I backed it down to 2.01v and now it works fine.
I just ordered a 1700+ 'B'. :D
Hopefully I can get it upto 2.5ghz like some of the others I have seen. 1860mhz just isn't cutting it!! ;)
some more bad news:( , I found out that the problem with my system not wanting to run my memory higher them 174, the more I increase the cpu volt mod, the more errors I get, I think there is a conflict, can somebody confirmed this:mad:
dammi* now I get the same issue with my r9700, what could it be?
Guys do you think by putting washers on the bottom of the screws that grap the board to the case might help?:confused: :confused: :confused: :confused:
Nunez, could it be that your hitting the capability of your ram? I have a 256mg Samsung pc2700 and I cannot take it more than 178fsb at even the most relaxed setting. My OCZ on the other hand goes as high as my mobo can take it.
no, you don't get, in simplier termsQuote:

pc with mod, max 174 4-2-2-2
pc without mod, max 200 4-2-2-2
this is also happening to my r9700, the more voltage the gpu gets, the worst the performance of the memory, just like the cpu
:mad:
this is an issue, cause I need more voltage to be able to run the cpu real fast, but in return the memory is doing bad, when both are used at the same time, dammi*, Now I remember that a friend told me that if a board is not designed to run cpu volt up to 2.2, there might be problems getting one that only does 1.85 to 2.2:( oh well, thats life,
solution, new mobo, or just get half and half:rolleyes:
need help...
wath for a resistor should i use when i dont want to use a VR to get vcore to 2,25 and vmem to 3,3V
You won't be able to hit 2.25v on the vcore... most people top out at 2.12-2.18v.Quote:

For 3.3v, hmm... I think that would be around 11.5k? When I was @ 12.6k I believe I had 3.2v. *I think*. I could be wrong.
sorry for being a tard, but i looked through the first page and couldn't find my answer, so my question is, what do I use to connect the wire to the chip? Solder? Glue?
Sorry for the dumb and probably repetive question :(
I used an SMD Grabber, I would NOT recommend glue for this mod, either solder or use a grabber. I put some pics in this thread somewhere...Quote:

what is SMD grabber? Can i buy it at radio shack?
No. Radio shack does not have them. Fry's does if you have one near you, or you need to order from online. Here is some more info: http://www.xtremesystems.org/forums/...&threadid=1152Quote:

cleoent: Awesome man! :toast:
SMD grabber is a little hook that you use instead of soldering into the board to make the connection, good for people like me that don't have any experience with soldering :DQuote:

yes you can buy some grabber at radio shack but they are in a form of hook that looks like and L with one stringe coming out which is not as good as the ones found at fry's or online, that has two and hooks more secured...
I bought some online for the mobo and I'm using two that I got from radio shack for my r9700, but I had to clue then to make sure then don't slip :D
so do these mods work on the non-deluxe too?
i got 2 15k vrs and 1 25k vr. i know one 25 and one 15 would do it for the cpu and ddr, but im not sure about the vdd. will the 15k be too much, too little, or just right for the vdd????
Woa there! You need 1 MEGA OHM, or 1000K Ohm resistor AND a 1 MEGA Ohm variable resitor. 25k aint gonna cut it!Quote:

Thanks so much for all the info guys. I am gonna get all this stuff as soon as possible but I need to find a good online UK store that will ship all these goodies to me in Ireland.
Anyone know any good stores.
maplin.co.uk have a nice collection but I can't see any 25k resistors there.

can I use two VR:s in the vmem mod? If I can then that would be great since i have two 10kohm VR:s here on my desk. Going to buy a 47kohm VR for vcore mod tommorow and I already have done my vdd mod.
yes you can, just remember that when you hook only one end to each other they will add, while you hook both ends they will be subtrate, can't remember but I think I'm right, but to make sure use a multimeter to make sure, don't want to kill the board, right? :DQuote:

Where I can read Vcore directly on board? (not by software);)
Thanks
bugs: I'm not sure, but you can just look in the bios...
I don´t like BIOS readings either...
My psu is giving 5V e 3,33V exactly and in BIOS there is 4,8V and 3,2V.
So I decided to meassure Vcore on the same IC and pin where the Vmod for Vcore is done, here...
http://www.maximumoc.com/img/hardwar...pu_labeled.jpg
And whit 1,8V choosen on BIOS, there was 1,79-1,80 V on my multimeter.
For Vdd I used this point for monitor...
http://www.maximumoc.com/img/hardwar...n8x/vddmod.jpg
And there was 1,55-1,56V
I just want to know if, when I done the Vmods, I can still read my voltages on the same points.
Thanks
Hmm well, I don't know about measuring the same pin. I would tell you if I had an A7N8X on me but I don't. Perhaps if someone else could check....
As for the same spot for the VDD, yes you still measure from there after the vmod. But I'm not sure bout the cpu.
Ok, thanks anyway.
Guess I should ho ahead with the Vmods, calculate depending on resistor wich Voltage should I get in those points, then measure and compare with BIOS readings.
Anyway if anybody knows a good Vcore reading point (pin), please post it here :toast:
Regards
No, not really :p. I'll just check with a multimeter. Thanks btw!Quote:

Hi there,
Have done the vcore mod and all works great. But I have a problem…
When I Set FSB/Mult to 215X12.5 @ 1.95V - All looks good - Rock Solid. But when I move to 216X12.5 @ 2.0/2.1/2.2/2.3…V - Cannot get a good stable rig. I noted that when I go up that High (2+V’s) A> the fan connected to the Mobo CPU FAN Header slows down and the B> Core voltage drops when I start a CPU test.
– Is this a problem with my PSU? – using an Enermax 550WAT
– Is it the voltage of the mobo? – if so can I mod that to?
Can some one help me?
Do theise mods still work for the rev 2.00 A7N8X Deluxe's ???
Thanks :)
BLue078: Yepp, I can't see why not! Also roky has one :D
:cool: I'll round up some VR's tomarrow and give it a try.
I need more vdimm 2.8 sucks
Hi there,
Rev 2 works AOK on the VCORE - Have not done the Vdimm yet..
In relation to my previous post. It was indeed the PSU - it was not able to sustain a stable supply of current to the Mobo/CPU (Fans slow down - erratic V readings)
Replaced it with a Server class PSU (Enermax EG851AX-VH) last night... Initial test results are good - Brought the unit to a Vcore 2.06V - Rock solid and also as it happens got my best OC to date (12.5X217) rock solid .
Moral of the story – if you want to go with a High Vcore get a goooodddddd PSU
ROK

hi,
i wona have 0,2V - 0,3V more v-core but i won't have a VR. can u tell me which resister i need?
hi, plz help me
whats the maximum and whats the minimum V-core u can get with the 25k VR ? with the bios settings 1,65 V
I am using a 50K VR - but figure that U should be able to go from 1.7V - 2.1V+ ...
I use a 50K and easily get to 2.1,,,so theres some left in it..
Way I have it is at +.05 for each setting in bios until I want to bench,,then I set it so its at 2.05 at 1.85 in bios.
HI,
Have noticed that my vCore becomes erratic above 2V going up and down like crazy i.e. I set it to 2.02 and under load it may go up to 2.05 and then drop to 1.95v! .
Does anyone have idea as to what might be happening and what I can to do to resolve it?
Not sure....mine does that as well...Quote:

Thought maybe is was my psu, but after the mod made my rails solid and high, still does it.

But mine doesnt flux that much,,maybe .02 or so.
How does one make the Rails solid and High?
You need to tell us what psu you are using in your rig bud before we can help you.
It may be something simple you can do based on your psu maker and model, or it may take a vmod or 2.
I think it's most likely the PSU, or some mosfets on the board are running hot (causes fluctuations too)
Hi there, Thanks for the help thus far Guys.
My power supply is en Enermax EG851AX-VH. - In reply to post 158
I have also noticed that the cluster of 4 mosfets (above the AGP slot) run quite hot even with a passive heat sink. - In reply to post 159
ROK
really? on my board they are only getting a bit warm. ~40°C...maybe 50°C
but not like 80°C on my 8rda+!!!
i got a question im plainin to vmod my a7n8x ... wont be a too big prob ...
my question is : do i have to set the pot to min or something so i dont get like 3 volts and kill the system?
the first start after the mod u know... or wont it boot if i set it too low?
thx in advance
X
At first boot you need to set it at a high resistence so that the voltage flow is low.
After a boot, check your voltage at the measuring point and adjust from there. Depending on what pot you used, you will need to be very careful how fast you turn that puppy.
bump!
is there a Northbridge voltage mod for this board? Ive been told to raise it from 1.5 to 1.7 if i want over 200fsb....
oh and hi btw :)
http://www.maximumoc.com/
There are several links at the top of this page. Click the one named "Guides and Articles". You will see a listing for A7N8X.
I am not sure if you have looked into vmodding the A7N8X b4 or not, and whether you are familiar with its component placement on the mainboard, but sometimes people call the North Bridge vmod the South Bridge vmod simply because the actual mod occurs near the SB chip. Not sure what moddin the SB would gain someone in the first place since it controls USB, sound and stuff like that.
There are several ways to do the NB vmod, but I recommend the one where you solder the resistors to the chip versus soldering to the itty bitty little thingy...as you can heat it up to much and it falls off, then you have lots more moddin to do to get yer board working again. Be sure to either have a very small smd grabber, or a high power mag glass and steady hands as the legs on the ic to which you are soldering are uber tiny.
GL and happy moddin.
How well is A7N8X in high FSB compared to 8RDA+ and NF7-S ?
My understanding is that the NF7 is a better performer, which hurts to say as I own the A7N8X. However, people have also hit very high fsb action on the A7N8X, but it can take a little work of course. You need to do the mods and have proper cooling.
For example, after the vmods I added colling to the mosfets as they were really kicking out some heat. Also, all NF2 boards are sensitive memory wise. The little buggers are picky to say the least. At first I had Corsair in my board, crapped out..but now it is stable.
Given vmods, proper cooling, and good quality mem, I would wager the boards you listed above are all comparable to each other. Put it this way, many many people have hit insane fsb on all the boards. Depends on how far you wanna push your components. Are you willing to push up that vdd and vmem to get those fsb speeds.....are you willing to say buh-bye to your warranty (unless you are one bad ass solderer or use smd grabbers)....?
Man very nice, where did you get those grabbers?:slobber:Quote:

Lets see, you buy the SMD grabbers and the VR and you just attach the grabbers on the VR and a away you go? Correct me if Im wrong, I really need to do these mods.Quote:

Well, almost that easy, be sure the VR is set to the correct resistence just to be safe.
Attach the grabber to the leg of the IC you wanna mod, then attach the grabber to the VR..dont forget your ground. :hehe:
Thnx a lot bro, if you dont mind can you possibly map me out a pic on the whole procedure. Advance thnx! :D Appreciate it :DQuote:

Check out www.maximumoc.com for a full write up including pics of all the vmods available for the A7N8X motherboard.
Click on "Guides and Articles" at the top which will take you to the "Guides" page. You will see a link for the A7N8X vmods in the middle of the page. It is very well written and easy to follow. The only difference is that instead of soldering the wire to the ICs you will be using the SMD Grabbers instead.
If you are still confused just reply back. ;)
Any body know where the vcore failsafe is set on A7N8X (rev 2.0) Series MOBO's is set at. I recently did the Vcore volt mod w//excellent results: FROM p95 Stable at 2.26ish to rock solid at 2.375 and still testing/pushing.
I've heard it is set at 2.1 but I get no shutdown at 2.15, have seen posts on other forums stating running Vcore at >2.2.
Where is it set(rougly) and does any when have a clue as to disabling or upping it.
Thanks in advance,

This is a prob that a few are working on now. I have upped mine to 2.15, she died loading windows, but me thinks that was a cooling issue versus any fail safe. We are mainly looking at the IC that you would do a VCore mod on: http://www.maximumoc.com/img/hardwar...pu_labeled.jpg
The theory is possibly cutting one or 2 of those legs would get rid of any vcore limitation...but there is no definitive proof yet as no1 has tried it.
There is a method that was developed by the finnish I believe that allows for 2.35... but the pictures were always too garbled to understand what the heck they were doing, and no one could get in contact with whoever took the pictures hehe... But dang 2.375... that's nice!Quote:

Im still semi-confident that what I described here will work, although I havent had the oppotunity to test it out myself.

Hey peepz.
About the Vcore measuring: I don't trusted my speedfan readings (1,79V atm) so I wondered where I could measure it myself. Offcourse the dots of solder un the underside are on the same voltage as the core. But I cant reach that atm.
So what I did, is measure it on the pin where I soldered the pot on (like I saw someone do a few pages back). It said 1,59V
So I dont think thats the right voltage either. (actually pretty logical if you know how a V-mod works :) )
I'll keep looking for a nice spot, or I'll just have to turn the mobo upside down...:rolleyes:
What would 10k on the vdimm give me?
what does VR stand for and what VR will i use to do the vdimm mod? also, how much voltage will i be able to give vdimm after the vdimm mod?
VR stands for Variable Resistor. Alot of people call them Pots, which is short for Potentiometer.
You should use a 15k VR or so for the Vdimm.
http://www.xtremesystems.org/forums/...&threadid=5167
You would be able to give it all you want pretty much.
Not sure where it stops at, but you would want to STOP before you hit it's max voltage ouput.
Hey guys justed done the mod to A7N8X-E Deluxe hope its the same mod well i put a 50k variable resister for the vcore and 20k for the vdimm but when i plug the earth in the fan header she wont boot take it off and it does any ideas would be appreciated
cheers
Worked it out guys prob was the core mod took it off vdimm is working fine so will have to have anoth go at it
Vcore IC:
http://www.saunalahti.fi/~chedu/team...8x/L6917BD.gif
VSEN mod?
I put 50k vr to 10. leg with no effect (also tryed ~ 30k). Mobo doesn't boot if vcore is over 2.15V (multimeter), but I can put over 2.16V (when windows is running) and run pifast/superpi.
(Bad English)
I know I am kind of late. But will this mod work with Asus a7n8x-x.
Thanks
If the layout of the board is the same, which I think it is, then yes.:) I think "-x" just means more features on the board, right?
Can I do this mod to a A7N8X-E Deluxe?
Thanks! :)
