Highest VDIMM

[[XC] moddolicous]

I know everyone here has upped their voltage to their ram, but how far did you go up to. Post your highest tested VDIMM
Mine- 3.8V

[blinky]

cpull did like 5.2v i think

[enzoR]

4.2V on Ch-5

[Cranox]

3.9v on bh-5

[Flib]

3.85V on BH-5 (higher and PSU shuts down - I hate the OVP!)

[enzoR]

too bad higher than 3.8 didnt help with my ch5. how about with yours?

[Maelstrom2160]

3.7 on bh-5

[Unseen]

my winbond :)

[Jeager]

3.85 on BH5/6

[RaVeN155]

bh5 about 4,1v but everythink over 4v was unstable. http://gorajec.net/raven/szalejemy.jpg <= higest stable frequency on 3,95v, maybe it would go higher with some sub-zero temps on nb ;)

[Flib]

that is a bad result for 4V Raven!

I got 270 @ 3.7 so 280 should'nt be a problem with a fan over them and throwing to them 3.8

[gclg2000]

3.85 or so on some Mushkin level 2 BH5 with the OCZ booster

[STEvil]

3.95 I think. BH-6

[RaVeN155]

@Flib - i think that my mobo just dont like me ;) (nf7) even 2v on nb doesnt help at all

[eshbach]

4.12v on bh5 gave me a 300 2-2-2 screenie i posted here a while back.

[SteveOCZ]

4.5V for about 2 hours.....did get any higher FSB than I did with 3.75V using 2x256 BH-6

OCZ is awesome, try to find a Dell employee who has given RAM 4.5V

If you still have it, can you post it here?

[varzmaster]

4V on Corsair TwinX512-3200LLPT v1.1 (BH-5). Abit AI7 could only let me run 250 MHz 2-2-2-5 (memtest stable)... the same results as with 3.4V. :(

Any higher voltages resulted in PSU OVP (Antec SmartPower 350W).

[funkflix]

3,76V with 2 x 256MB Corsair BH5.

[zyx]

3.7+ on bh-5

[blander]

3.9v mushkin pc3500 level2

[sandman]

3.54V on some BH-6.

[Holst]

5.5v through my old crucial 2100 sticks on an 8k3a+

Board blew up afer a few benches.

I soldered the 5v line straight to the Vdimm.

The sticks were allready bad so I didnt get any particually good benches, i think 180fsb was the best I did

[masterofpuppets]

4v on BH5 with a vdimm mod.

[RoJo]

First post so Hi all.

I have a question about putting voltages of 3.8 and above through you're ram. Are these high voltage settings that most of you are running for 24/7 useage, or just settings for benching and the such?

As I have to sticks of OCZ VX ram at 3.4v with a OCZ booster at 255 and 2 2 2 5 timings at the moment. And was hoping to push my ram to 260 with higher volts.

I have the ram and the booster well cooled and was going to try and push the volts up. But don't want to damage my cpu (FX55) or ram in doing so.

Cheers...

[meke]

3.8V to Vitesta ddr600.
no change from 3.3 to 3.8.

Man this sounds like a good anecdote. At least it made me laugh :D

On the topic: only pathetic 3.3v on BH-5. But that's only because I'm still learning to solder reliably.

[mcnbns]

I've had my EB up to 3.4v, but it didn't help because my mobo is holding me back.

[Veritas.no]

3.75 on 2 corsair 3500 512 MBs. Only got like 261 stable :/ Would have liked 0.3 volts more. but my Antec dosn't want to go higher than 3.9 :p

[Kamerat]

4,56V by accident (measured by voltmeter), the Booster is dangerous. :mad: Used 2x 256MB Corsair XMS3500 BH-5, doesn't overclock more past 3,90-3,95V.

The OCZ booster? It will not go over 3.9V unless you mod it then you can hit 5V :)

[Kamerat]

No need to mod it, the voltage of the booster varies with the 12V line (this by using an OCZ PSU). Tried again with 4,32V, display on booster only showing 3,9V. One problem is that the booster uses the 5V line as reference, if the 5V line isn't 5V the display on the Booster shows wrong voltage.

This is dangerous for people not knowing that, the 5V line must be exactly 5V and the 12V line must be 12V for the booster working the right way. With higher voltage on the 5V line than 5V the Booster shows lower voltage than it gives and lower than 5 it shows higher voltage.

Tested again with 12V line at ~13,9V, 5V line at ~4,6V, display showing 4,8V, actual voltage is 4,32V. With 5V line at ~5,8V, the booster only showed 3,8V, boster still giving 4,32V.

[Ferry82]

3.9-4.0 on my bh5 with booster.

[enzoR]

:eek:
how could you guys let that happen... :( :stick:

[funkflix]

Oh, i forgot something!

12,4V on my Infineon 6A (BH6) :D

[kryptobs2000]

how did that turn out?

[funkflix]

:explode:

;)

[kryptobs2000]

I see haha, why'd you waste the... well ram, mobo... w/e else got fried in the process?

[funkflix]

Ram + CPU, but it was an accident! :-\

[Mag Master 21]

3.6vdimm with 3.74 on the rail.. My Powerstream won't go any higher.. At 3.6 I'm into windows and can run Sandra at 270 (4200mb/s) with A64 tweaker settings all tight.. It's superpi stable at 265.. I wanted to hit 280..

[JDizzle]

Oh, i forgot something!

12,4V on my Infineon 6A (BH6) :D

Hah, how did you manage to do that?

[funkflix]

Hah, how did you manage to do that?

Connected the +12V directly to the Vdimm Cap. ....... :D

[enzoR]

so how is that an accident? :D ;) :stick:

[funkflix]

I was a bit deflected while i modded it, and i choosed the +12V Pin, dunno why .... :slapass:

[enzoR]

lol :D
poor rams though :(

[[XC] moddolicous]

12,4V on my Infineon 6A (BH6) :D
Did the board post or was it just fried once you started it.

[funkflix]

Fried up from the start.

[enzoR]

with smoke + flames? :D

[overcrash86]

my DFI NF3 250Gb didn't go over 3.7v vdimm and my PSU didn't go over 4v it shutdown at 4.02v :brick: over 3.7v of vdimm i dont boot
then over 3.88v of VIO that my PSU to shutdown ,to go to 4v VIO i use the voltmeter under windows ,then with the 3.3 to vdimm that 3.88v max.

i would go to 4v vdimm any suggestion for help me :confused:

MY PC2700noname go to 260Mhz CAS 1/3/2/5 at 3.67v bios (~3.75v real)

[funkflix]

with smoke + flames? :D

Not really, stick looks great, but it's damaged! :-)

5.2V on some early early EB/Booster tests. Unfortunately a couple of chips didn't survive. ;)

how did u get your antec tc 550 lines so high?

[funkflix]

how did u get your antec tc 550 lines so high?

tc = true control = adjustable Rails! ;)

Edit: Ups, u have that PSU too! Hmm, i'm wrong with the adjustable rails?
Is it a other Antec?

[Naasar]

tc = true control = adjustable Rails! ;)

uh..ok.....

i have the psu and adjustable rails wont go that high. especially the 3.3v line maxes out at 3.33v :confused:

the 12v line goes to about 12.4 and the 5v line goes to about 5.1

[funkflix]

Sry, look at my Edit. :)

theirs a mod for it ;)

[Naasar]

theirs a mod for it ;)

care to share that with me my fellow member? :stick:

[enzoR]

i'll go find it in the xtreme mods section for u :rolleyes: :)
brb ;)

edit: umm ok. as far as i know your PSU also has feedback lines? then this (http://www.xtremesystems.org/forums/showthread.php?t=37574&highlight=antec+550+mod) should work shouldnt it? :confused:

[X-GeN]

3.7v on a 256mb Twinmos ddr400 M.tec (Winbond bh-6 i think)

260mhz 2-2-2-5 2T

There was no heatspreader, just a 2400rpm 80mm fan blowing over :D

Did it on 8kda3j with Vdimm mod

[funkflix]

256mb Twinmos ddr400 M.tec (Winbond bh-6 i think)


Thats afaik the new Infineon/Winbond UTT, same as the OCZ VX have! ;)

4.8v BH5

2 turns in the wrong way, humm
:D

[andL64]

3,85V Kingston BH5 @ 280 1,5-2-2-0 :D woOhOooOoO

[enzoR]

did it again... 5v with CH-5

[Zanr Zij]

3.8v on BH-5 256MBx2, 4.0v on BH-5 512MBx2 :D

[STEvil]

played with 3.7v trying to get 250mhz 2-2-1-11 to go on 2x512 ch-5.. no go.

3.4 is good for 246 2-2-1-11 though, so probably board hitting the limit (nF7).

[Rabbi_NZ]

3.4v on VX... would go more but I cant with current hardware.

[krampak]

4.3V on TCCD, one of 2 dimms died. (by accident).
