ASRock 939Dual-SATA2 VCore & VDIMM Mod

[Conroe]

I will, it works on a p5p800.

Now I have Stock cooling, and running my 3200+ Venice over HTT 260. With more Vdimm I may still need the devider. All it will do now is tighten my timings from 2-3-2 to 2-2-2. But I will try it, along with Vcore mod when I get a better HSF.

Any way, seems smarter than using a resitor. Current will not be constant, the voltage will change way too much. This is a good regulator, better than the one on the mobo.

I see... Well, I can only wish ya good luck... Nevertheless be careful or you'll get a fried mobo...

hi all! im brand new to this forum so i hope i posted this in the right place.

i came here because i saw the volt modding for my board, the asrock 939-dual sata2. i performed the vcore volt mod and it worked great. i have a few questions on the vdimm tho.

for the vdimm modding, i will b talking about the variable voltage mod. it looks liek the best for me, because i have TCCD, and everythign else would b much too high.

anyways, i went to radioshack to pick up a 500 Ohm resistor, but of course, its my luck, and they didnt have any. the 2 closest was a 470 Ohm resistor and a 560 Ohm resistor. i bought one of each.

i was wondering if it would b possible to perform this mod with any of the resistors i picked up, and wat a rough estimate of the voltage would b?

thank you

PS: HELP!!!

I have made the variable vdimm mod with a 150 Ohm resistor, It worked great on Value Ram, but today I installed my new TCCD and I get nothing but instability, I think you should wait untill I get this problem solved out....

Happy Christmas...

About the Vcore .

I was wondering about the Vcore I have the Vdimm all together with the OCZ DDR ram booster and now I was wondering if any one knows how to get 1.7 volts for the Vcore ? I would like to beable to get 1.6-1.7 and as far as I can see there is no way at this time to get that . am I right? I hope not . some one please tell me I am wrong .

I haven't found such mod anywhere... Tough I searched for it... Now i'd just like to noe what's the real vdimm is, cause I'm getting soime instability from the Ram modules... maybe the BIOS is to be blamed... I'm using the OCW Beta 1...

I do not know what the real Vdimm is but my DDR bosster is set at 3.1 volts .I am using OCW beat 3 and beta 4 is now out but I do not see a use for it at this time.

Do you know if the Boster works to turn the voltage down? I think the Vmod is too much for my tccd...

I think it does . it will override the bios and take the Voltage of the Ram upon it's self . so I would have to say yes it does . since it totaly over rides the bios settings and all.

 

[W1zzard]

i dont think the booster can reduce voltage below what's set in the bios .. anybody wanna try?

 

[c3l5o]

trickson would it be much trouble if you tried doing that with your booster?

 

[c3l5o]

Just measured the voltage... Normal = 2.56V | High = 3.08V
My TCCD doesn't like either Voltages, one is too low, the other too high...

 

[trickson]

well I have been able to do it ! I have gone from 2.8 - 2.5 volts with the DDR booster . it does work.

Thanks, merry Xmas!!!

Thanks, merry Xmas!!!

any time! AND Merry Christmast to all and to all a good night!

 

[c3l5o]

Just one thing though, I'm gonna try a 500Ohm resistor before going out to buy a DDR Booster... Smarter move I think... Oh and nice smiley... Goes well with the season spirit!!!

Thanks I thought so. but on a serious note is there any volt mod that will give me a 1.7Vcore increase on the CPU ? Please any one I realy need this .

 

[c3l5o]

Don't think so, sorry... but to find it over www.ocworkbench.com

Merry christmas!!

this is a merry christmas now THANK YOU!! .

 

[c3l5o]

my turn need a vdimm wich gives me 2.75V~2.85V... anyone knows a way?

 

[trickson]

yes why don't you do what I have done ? I got a OCZ DDR RAM Booster and I can set my OCZ gold as high as I like and it is a no brainer and no soldering or resistors required!

 

[trickson]

well i decided to do the Vdimm Volt mod and it is a sucess ! now I can take out the DDR ram Booster ! it is taking up room in front of my HSF for the cpu. so my only question is how do I know what my vdimm voltage is at ? I did the 3.2 one and I know it is working I have this system O/C'ed to 2.7GHz and it is stable too! is there a programe that will tell me what the Vdimm is? thank you. I also noticed some thing odd. when I shut the computer down the power light stays on now can any one tell me what I did wrong thank you.

 

[c3l5o]

Cool, can you post some pictures?

 

[trickson]

Cool, can you post some pictures?

shure but I am still wondering why the power light is staying on after this mod. Is this normal? or did I screw some thing up?
well the pic's did not come out right I have a digital cam that is not all that good .
