trick to get more stable vdimm on the dfi nf4!

[Jasonxxx]

glad its helping

3.5v is stable and clean? does it help you to get higher than 3.4v vdimm?

Yes, 3.5 is stable, It seems more stable.... I use 3.4v for 255mhz... I will be able to test 3.5v this weekend and see if gives me anymore mhz than using the 5v rail....

I think this the way to go unless you would have to get your 3.3v line over ~3.7-3.8v..... @3.6v I'm ~8.3% over the 3.3v spec which shouldn't hurt the SATA harddrives at all....

saaya any modd to get more than 4.0v? , i get this board soon and my bh5 memmorys need to feel some power

[jinu117]

Few PSUs i wouldn't try this on granted it is same as vcap mod.
1) PC&P 510 Dlx.
2) Enermax (pre noisetaker models)
I've had friend who would consistantly kill A64 memory controller doing it on above 2 PSU. He moved on to OCZ Powerstream and had no more dead FX-55 (well at least on memory controller). Zippy is another one that worked fine for months... where is my zippy now... hmmmm -_-;

Here she is.....looks a little different now, eh?

Most Bh-5 don't like that kinda voltages

[TEDY]

with my TAGAN 480W this isnt possible, right ?

[xgman]

Does this trick help the warm boot problem with VX type ram?

Like and like To bad its summer here now but when the winter come back and the bh5 feel -20 temp they wants more power

Yeah... cool temps do help. But I don't have them inside my rig room

why not?

lastviking, really nice to see you again

well about lower temps, tom holck just told me that his bh5 doesnt like to work below 0°C... wich makes sence, if you cool the memory or cpus the resistance decreases and more current flows through the traces at the same vcore, and if the temp gets too low too much current flows through the chip and can kill it or stop it from working properly ie cold bug @90nm a64s...

[Techwarrior]

What is the best way to measure 3.3V rail without a multimetre? In BIOS I'm guessin?

[thesaucier]

I would guess the standard line you would get from any company... they only guarantee and warranty "operation within specified conditions"... meaning +/-5% on the supply rails. But since when does the "warranty restrictions" have anything to do with Xtreme Systems or OC'ing in general ? Besides... without undo expense relative to the MB price, they couldn't tell.

Peace

*insert standard disclaimer about not trying this at home and proceed at your own risk, blah, blah, blah*

LOL thats right!

Well, Vcap mod was just me half a sleep typing... the 3.3v line cap mod to vdimm :P

ok gogin to buy a multi in liek a half hour. Have extra jumpers from mobo. So I measure 3.3V Rail on either 24Pin connector or Vmem spot over top of DIMM1? Also I notice My SATA Hard Drive is running off the 3.3V rail( orange wire i nthe connector ) Is this going to fubar my drive. How far can I go? 3.7 ok? that will give me about 3.4-3.5 on Vdimm, should get me to 250 2-2-2-5 hopefully

[Magnj]

ok so reding from the bottom pins of the 3.3V/5V jumper I adjusted from 3.3( exactly, nice job ocz :P ) up to 3.7. Almost had a heart attac when the lead wire hit one of the bottom pins on the 5V side, but booted right back up. Then I switched jumper, again almost a heart attack getting my hand in my case to the jumper, got them set then when i booted i got a series of 5 or so quick POST kinda beeps. Turned it off. Check my connections, booted back up fine. Adjusted bios to 3.5V. Smart guardian reports 3.47Vdimm. Is this correct so far?

Gonna go push my memory now.

LOOKs good to me!

[Magnj]

yea. I eventualy bumped it to 3.79 ran 2-2-2-10 at 3.6V. Looped Memetest all the way through about 5 times. Tried to boot window, went in. It crashed. Now it does the XP loading screen but instead of going to the login it gives me this screen that says windows XP, Looks kind of like an install screen. But nothing ever comes up. If I alt + TAB I can see 2 tasks running. Windows log in and Log into windows? Thins the voltage corrupted my SATA?

Yup, sure sounds like it.....have you tried lowering your fsb to boot into windows?

[Magnj]

yea Im back at stock 3.3V rail and 200FSB...still giving me his goofy screen. THink I can save her?

[saaya]

the bios is totally off on the dfi and some other current boards, i wouldnt use the bios readout to adjust any rail or voltage!

Well, Vcap mod was just me half a sleep typing... the 3.3v line cap mod to vdimm :P

ah ok
that mod doesnt work on those psus? hmmm didnt know that

yea Im back at stock 3.3V rail and 200FSB...still giving me his goofy screen. THink I can save her?

hmmm you might have corrupted your windows install because the mem wasnt stable at that speed... or you corrupted your windows install because your hdd was overvolted? hmmm i hope its the first... do a repair install of xp ...
good luck!

well if its the hdd then we at least know that some sata hdds dont like 3.9v...

[Magnj]

mem ran through memtest full through like 5 or 6 times. No errors

Can't sem to get XP to boot from the disc I have. I get the windows loading screen like right before the login scren. Then I get this screen, with a windos logo on it. It kinda fades in. ut theres nothing there. If I alt + Tab I can see " Log into windows" and "Windows Login". I guess I'll keep trying to boot from the disk.

and it was 3.79V not 3.9. I'm pretty sure the HD isn't damaged because Windows tries to load up. I probbably messed up the registry or something when it shut down all nastily. Ugh. I don't have the origianl disk I installed windows from either, I'm using a differnet disk. Ugh I hate overclocking :P

[saaya]

no, i meant maybe your mem wasnt stable at the speeds you were running when windows corrupted? so thats why it corrupted... if the memory is stable now its still corrupted and wont let you boot

3.8v on the 3.3v rail hmmm thats above 10%, it could have damaged your hdd or made it freak out and corrupt windows... but id be surprised if thats the issue...

[Magnj]

ok well I tested in memtest my memory at 248 2-2-2-10. And at the moment I can't recall what i booted into windows at but i think it was either 248x10 or 245x10. Either way my rail was at 3.79. So it was memtest stable? Memory is definitly stable now 200x11 2-2-2-10 at 3.2V. Should I try reseting CMOS? Gonna suck redoing my settings but i guess not worse than losing os

[saaya]

memetest stable =! windows stable!!!

many people think that if memory is memtest stable its rockstable, but thats not the case...

[Magnj]

super. So what do you suggest? I cant get into windows. Just that screen. Resettign CMOS now, how do I repair my OS install?
