Will it?

Well I just got a PM, or an E-Mail....

"just needed your advice, I got the asus a7n8x non deluxe and I try the cpu volt increase with the vr and nothing happeneds, I check all connections and different resistor and nothing, can you please help me out!"

But what I'm thinking is that he may not be turning the VR enough... or if he is, he's turning it the wrong way heh...

So when he gets my reply hopefully he'll try turning it more and it will work :)

I try three different vr, I try 25k, 47k, two 47k together, I have a volt reader that I check resistance, I did my r9700 so I did something right, back on the case, I got good ground, try from mobo and chassis, the only think I notice is that the name of the chip is different than the one for the deluxe, I think the mod is jus for the deluxe.:(

sysfailur, how can I check the vcore with tester, I think the software is not working properly, want to findout direct, tnx


:)

I think if you poke around on the mosfets by the CPU, on one of those pins you should get the CPU voltage. That's how I got the memory voltage, so just check around there ;)

I try them, no luck:rolleyes:

Sysfailur,

You have the A7N8X Deluxe?

Guys, whats the highest voltage with the vomodd you guys can get, without the OVP kicking in? I did the Vcore modd, but somehow the computer will froze when the vcore are higher than 2.1V:mad:

The highest I have been to is 2.05...

hi,
just a question:

is it a Crystal ORB on your NB? does it fit into the original holes of the passive cooler which is installed by ASUS or did u use the pad?

thx!

Yes, crystal orb. I scraped all the pink crap off the NB and used AS2. Yes the ORB fits in the stock holes.

k, thx a lot!

i scraped the pink crap off the NB and used also AS2 but i had to use the passive cooler again (i have nothing else here at the moment). but if you say it will fit into the holes, then i'll try the Crystal ORB too :)

I have the Deluxe version, yes.

sysfailur,

did u use for the Vcore mod a 1/4W 25kOhm resistor? or did u use a VR? i dont know how much W it must have... i think 1/4W or not?

how much Vcore do u get with the 25kOhm resistor? over 2.00V?

thx ;)

the best thing to do is get a 50K RV and it will give .05 over the one selected in the bios, from there you can increase untill you reach the volt you need or the fasety thing kicks in and shuts the comp when it reaches the limit;)

Well I threw the boxes away so I can't tell you. If you see in my pics (on other threads) my VR's are humungous. So maybe they were a larger wattage. I'm not sure. I have actually disconnected them and I will be putting on smaller multi-turn pots.

I have gotten up to 2.18v on the core and as much as I want on the mem.... 3.59v (by accident I had it that high).

I think its time we add VDD voltmod for the a7n8x to this thread, dont you think? :)

Hi nooby here,If I use a 25k VR and set it to its lowest setting, what kind of vcore would I be getting and will this fry my mobo/cpu? Also how can i test the new vcore so i can reference it to the bios vcore?

well, if you do that, that and checking if a gun fires filled with bullets while aiming at your head wouldn't be that far off:stick:

seriously, don't do that, get yourself a 50k vr, set it to 50k, that will give you around .05 over whatever is selected in the bios, from the lower resistance and youre set:banana:

No way I will do that with my board lol. Ive never voltmoded b4 and have never seen a VR before, just wanna know the worst case scenerio if I did it wrong. One more thing, if I get the 50k vr and set it at 50k, would i be able to lower the resistor to get more than .5v? I figure i need .1v to be stable at 2078mhz w my 1800+. Thank bro.

example, bios 1.65, real, 1.70, ext

ok, and please make sure you get a tester so you know the resistance before aplying it to you board,

VR, have three legs, you only need to use two, the center one and one of the other, but when turning the knob will change depending on the outher leg you choose, the tester is handy in this case because you can check which way will give less or more resistance:)

and looks at this I this my first mod, like less than a week ago, so I can tell you this is very simple but you must be careful, I did my mobo, and my r9700:banana:, good look and have some fun while you are at it:toast:

Thanks Nunez1980, Are you saying that turning the vr will give me more than .05 that I need? cos Im at max 1.75v right now and I wanna get to 1.9 - 2v. Will the 50k vr sufficient or do I need a 25k instead or something inbetween?

oh, I see, check this out>

100K max resistance 100K, minimum resistance 0.0K
50K " " 50K, " " 0.0K
25K " " 25K, " " 0.0K
10K " " 10K, " " 0.0K

get, 100K or 50K RV is not a resistor, a 100K resistor is just a 100K can't change that, but with a 100K RV you can start at 100K and lower when needed.

this is why RV are good for mod because you can increase or decrease, while resistor are fix:smileysex is simple, but since you hadven't had any experience it feels a little complicated, but you will get it:toast:

Is a 50k potentiometer(??) the samething as a 50K VR?

Yes. VR (variable resistor) and potentometer are essentially the same thing.

can you please tell me how to tell the speed of winbond ram, and at what volt you got it in your nforce and bios version, tnx:rolleyes:
