DFI sli-dr voltage regulation is pathetic

[Repoman]

Hi everyone,

Just got a new sli-dr back today from rma, old one would not post about half the time. I expected problems with the new one, and of course I got them.

First thing, ballistix pc4000 wouldn't boot in the DC orange under any BIOS, only way they would boot was single channel slot 1/2 (no single stick, no nothing). I flashed to a few different BIOS's, finally tried 7042BT which allowed DC yellow, still no DC orange though, which worked fine in the other board. Also the DRAM voltage is terrible, at 2.6 I get 2.68 or 2.74, at 2.7 I get 2.74 or 2.77 and I haven't even tried 2.8 yet.

CPU voltage is also terrible, and it works different than the old board as well. 1.425+104 used to be 1.424 now its 1.456, I have to set 1.400+104 now to get 1.424. The voltage jumps around so much it causes me to fail prime, I used to be stable for 8 mins at 1.424v (1.425+104) now I'm stable for few seconds at 1.424 (1.400+104). CPUZ will report voltages change from 1.424-1.408.

I suppose it could also be my power supply, which has also been acting strangely. MBM5 is now reporting 12.27v, was just down at 12.08v couple hours ago, and just before reboot it was 12.14. I've never seen it up at 12.27 though, except now. That still wouldn't explain why the orange slots won't DC

edit: just thought of something, since I'm running lower BIOS set voltage than before, maybe it's trying to set 1.408 for 1.4+104(unstable, crashed on old board) but the PSU overvolt is making it jump to 1.424? Doesn't seem like that big of an overvolt though.. what do you guys think? It's an enermax 535w 34a.

Thanks for any help

[craig588]

Use a real multimeter, Oskar himself says that the measument chips are something like 5 cents and not even worth what they paid for them.

[Repoman]

^alright, I guess I could pick one up real quick.. but if PSU's good that just limits it to mb problem..

off topic: already got more help than I did on dfi-street :rolleyes:

[Daved+]

CPU voltage is also terrible, and it works different than the old board as well. 1.425+104 used to be 1.424 now its 1.456
:confused: 1.425 * 104% = 1.482... 1.456 is a lot closer to that than 1.424

[Repoman]

^I didn't necessarily say that was a bad thing, the bad thing is that the voltage jumps around. I could care less right now what it reads

I'm gonna be so pissed if I have to send it back again, finally got a good mount on my new slk-948u and just put it in my case, why didn't I do more testing outside!? Plugged all my drives in and everything.. dammit

I have vcore fluctuations on my DFI too...

[sauria]

Mine is more stable than my MSI board ever was.

[Repoman]

I have vcore fluctuations on my DFI too...

Really? My old one never did, stayed at one spot and was great. This one fails prime though where the old one passed because the voltage drops too low.

Should have just lived with no post on my old board, not like it's ever off anyway..

edit: remember guys, I'm not talking about dfi boards in general, just the one I got.. I just failed prime after 5 seconds on a 30min stable voltage, 1.456. Unless I can find a solution in the next week or two I'm afraid this one's going back too.. have to test my power supply as well though

[OperativeSix]

Use a real multimeter

Quoted for truth. My DFI claims my DFI's 12v rail is only 11.73v, but my trusty Fluke puts it at 11.98v. I'll trust a DMM any day over the cheapo stuff on the board itself.

[Repoman]

Yes, really...

Check this out:

I have the feeling it's NOT supposed to do that, are those spikes low enough to cause you to fail prime?

Mine are, and I fail within seconds on half hour stable speeds :mad: I have the feeling that leaving the chip on the desk for a few weeks didn't hinder OC ability..

I'll try to get some speedfan shots..

edit: WTF?? Everything appears to be back to normal, and exactly how it was on my old board!? 12v rail (according to software) is back down to 12.01. Mobo vcore voltages are set how they were on the old board, and prime doesn't fail instantly. Straight vcore line in speedfan, and i've been running prime 10 mins on 30min stable voltage, we'll see when it fails. Didn't do anything except turn power strip off for the night..

I really have the feeling the cheapo PSU sensors were right this time, maybe they were off a little, but I still think it was PSU overvolting. Considering the voltages suddenly are back where they were and everything is fine, and both DRAM and CPU voltages are set correctly, and not way too high. I'll see if PSU does it again in the next few weeks, if it does it's (enermax 535w sli) goin back and I'm getting tpII 550

What do you guys think?

edit2: failed after 10mins, I think it's cause temps are ~50 (used to be 40), this new bolt on doesn't cool as efficiently as xp-90 but it will once IHS is off :)

[Daved+]

Take some speedfan shots while priming please... I want to see how stable your vcore is. Thanks.

[Repoman]

Alright, I will.. sometimes it boots and the vcore line is perfectly straight, other times it's all over the place.

I'll take a shot when it's bad for ya

Also I had the orange slots working for a while with 7042BT when I thought it was all fixed. Flashed to 7042BTA and suddenly they don't work anymore :confused:

Only yellow now.. I think I'll try 7042BT again to see how that does, they're almost the same BIOS though so that confuses me

Welcome to the DFI world ;)

[Repoman]

Lots of weird things with this board.. sometimes it completely skips over the Main processor/Memory testing lines during post and just shows CPU0 Memory Information. When it does this, it doesn't do single beep after leds go out. Many times it will freeze before verifying dmi pool comes up, then it will restart and work. Sometimes it won't say DMI pool is OK, but it continues anyway. Also DC orange will post in 7042BTA but as soon as I enter the BIOS for the first time, it doesn't work. If I skip over the checksum error that you get when clear CMOS and don't load defaults, I can load windows and perfectly stable in orange. 623-3 doesn't work at all except single channel slots 1/2. I'm starting to think this may be a board problem as well as PSU prob.

edit: also, my -12v voltage is -9.40 and -5v voltage is -0.28. Do those matter?

Anyway here's one shot, I'll add more at different settings.

Nop, that's perfectly normal for the NF4s, they don't use the negative rails.

Thanks for the screenshot.

[Repoman]

Alright, can't get it at it's worst for now. It's like sometimes it's perfect (this morning, everything worked including orange slots) then right after that it went to terrible and I would get like .25v jumps at stock speeds (luckily I'm stable down to 1.09 so it didn't freeze). Now it's about medium, and that's the screenshot up there. I just bought a DMM off ebay so I'll know for sure it the PSU is bad, and I can test the actual vcore voltages.

I'm gonna leave the CMOS on clear for a while now to see what that does. I'm also just gonna run stock speeds since no OC speeds are stable. I'll wait for some input here and then I'll know for sure when I get my dmm. I'm out for the weekend until sunday morning unfortunately so no testing for me.. also just bought hl2 and css and I'm itching to play!

Damn these boards are weird..

[craig588]

A bad multimeter is just as bad as a mobo. If you paid less than 30$ for it, rest assured, it's crap.

[s7e9h3n]

This is normal. There will always be a voltage drop from the mobo measurement to the molex. For example:
http://img90.imageshack.us/img90/5787/11x290spi1m8ua.jpg
DFI Reads 12.03 - I measure my 12v with my Fluke27 @ 12.28
Sounds like the OP may have an issue with his mobo since he says that there were fluctuations with his MSI as well. @ Repoman - what psu are you currently using?

[sauria]

I still use my analog model from 1980 -- $26. Works fine. :)

[craig588]

I don't like analog meters, that's something I would still consider crap.

[snowwie]

DMMs are just simply easier to read, and they are still only like 15 bucks

[Daved+]

I don't like analog meters, that's something I would still consider crap.
I use a DMM but analog meters are a LOT better, you will be able to tell fluctuations that you won't be able with a DMM.

[celemine1Gig]

I don't like analog meters, that's something I would still consider crap.

Analog measuring devices nearly always have much lower measuring error in comparison to digital devices, which have to convert the original signal into a digital one (that's where the error comes from most of the time, but not exclusivly). ;)
So I wouldn't call it crap. :)

[craig588]

I use a scope for finding stuff like that. I don't trust myself with analog meters. I prefer a 5 diget resoution to the analogs analogness. (I'm aware of why they are better for certian things, I just can't express how effectivly)

[Repoman]

Do I have to measure both +12v rails? Or will they both be the same...

Anyway, I've decided to run this on stock or mild~moderate OC for now and just wait for the SLI-DR expert.. sell this one on ebay. :D

[eliminate]

i dont think DFI will change the expert that much. Though maybe we will get lucky with the new board

[dinos22]

yeah this voltage stuff is pissing me off.....Abit AN8 was showing proper voltage but this DFI shows 11.71V WTF.....what is the best and easiest way to measure voltages with a multimeter....bit of a n00b here but have a MM lying around somewhere I borrowed of a mate

[Repoman]

Yeah, I know.. but eventually I'll go SLI and those damn close slots will piss me off, also they said better PWM, and I think that's the cpu/dram voltage regulator

Not too sure though

[eliminate]

DFI keeps a lot of the same stuff with every revision. I think the only thing they are changing just to make some extra money is the spacing of the PCIe slots

WHAT PSU ARE YOU USING???

[Ubermann]

I ones messed up all volt readings when one fan came off from MB contact while running.
Volt jumped up and down after that and they were very low.
But with DMM everything was fine, so i guess the chip for measure on MB was wacked.

[Repoman]

WHAT PSU ARE YOU USING???

ENERMAX 535WATT SLI

12V RAIL= 36A

[Daved+]

ENERMAX 535WATT SLI

Now I know I can't blame my vcore fluctuation problems on my 20A@12v PSU.

[s7e9h3n]

TBH, I've never been a fan of 2x12v psu's - especially for the AMD64's. The motherboard and cpu alone can draw >225W from the 12v rail alone. So an underpowered 12v rail will indeed fluctuate if enough voltage is required by the mobo.

I think the new revision of the DFI will have a 4 phase power circuit instead of the current 3 phase one.

Asus has the 8-phase power board coming out....it would be nice to see DFI implement a similar design in their boards

[Revv23]

i dont really think 8 phase is nessecary, i mean, gigabyte has an 8 phase board out, and its pretty average oc wise.

[celemine1Gig]

The higher number of power-phases just can't help, if the components used are crap. :) (hmm, did I hear Gigabyte; no, just kidding)
I dare to say that a good 4-phase dsign can easily challenge a bad 8 phase one. :)
So the engineers should better try to create a really good 4 phase solution before constructing a overrushed 8-phase design due to promotional purpose.

[MikalCarbine]

I'm running my NF4 Ultra-D with my OCZ Powerstream 520

Everything is rock solid, vCore is undervolted but rarely fluctates .01 volt (readings from mbm5 though)

I remember taking my fluke to the 12v rail and it was pretty close compared to the motherboard readings

[Revv23]

not sure where you get that from, pretty much every dfi board to date has been vastly different then the previous.

not only are they redoing the power circuitry they removed the 5v jumper, the sli jumpers, added pci slots, and now they are using a different chipset.

[Jesus]

Did Iunderstood this thread corretly, that you are acctually belieing MBM and smartguardain? Just an example smartguardian on my old board ( the one in the sig) was telling me 12V@11.71, and MBM5 shows 12V@11.91V, my Multimeter 12V@12.01V rock stable.

This is just an example how different programs are giving different readings of the same sensor chips.

[uOpt]

I ran monitoring of my CPU voltage since this thread started (with the CPU overclocked from 2 to 2.55 GHz and under permanent burn-in load). It only varies between 1.50 and 1.52, with the 0.02 clearly being the resolution of the sensor. So no spikes. This is FreeBSD's healthd.

However, I set the CPU to get 1.55 volts, this is why I would like to do the voltmeter thing now.

[politenessman]

i dont know if this will make a difference to you or not, but if you can, check the serial number on your mainboard. i would bet its the same board that you rma'd with either a bios flash or a swapped out bios chip. this is not a jive rumor. i know from experience with 2 ultra d's and a 250 gb ut. if your serial number checks out the same (it will, unless the board you rma'd had grenade fragments in it or something), go on over to dfi street and see what they have to say about it. i think you will be suprised.

Where do I put the multimeter to measure VCore voltage on a DFI SLI-DR board?

The only way is to figure out which pins are power and ground on the 939 socket then plug in your MM (if you have probes to do that) to measure that, but you may easily destroy the socket. It's the same thing for Vram.

[MikalCarbine]

Aren't there points on the back of the board? I think I remember the NF7-S rev2 having em

[MikalCarbine]

Just tested my voltages with speedfan, apparently they aren't as stable as I thought. Instead of spiking down they spike up though haha. Hasn't caused any instability for I have reached 2.85ghz on 1.62vcore so far.

Also, would sinking the PWMC help the voltages at all? What about the unsinked mosfets by the socket? :confused:

[Repoman]

Heh, forgot about this thread. Anyway I got my DMM and measured 12v rail voltages.

12v changes between 12.09 under heavy load to 12.19 when I'm sitting here typing on the internet.

Is that acceptable? Or does this need replacement?

It's above spec, I say its acceptable. What isn't acceptable was my old Tagan that would spike from 11.89 (which is low to begin with) to 11.67 on my old mobo :p:

[Lood007]

I bought a cheap case once that came with a power supply (450W). I had already bought a thermaltake PSU to put into it (building for a friend), but I decided to see how awful the PSU was. It was a POWMAX lol.

I turned it on, and while installing windows, i measured the voltage with a DMM.

^Damn, that sucks, I also had mine at 1.52 @ 2650 and it went down to 1.5. Crashed when vcore slipped :mad:

BTW your 12v is very high! Mine is anywhere from 12.09-12.19 .. :(

[MikalCarbine]

Sould I lower it a tad? I always see people with 12v at like 12.34 and such

[Revv23]

my 12v is at 12.39 no load 12.2 loaded, this fortron has alot of power but it doesnt hold the volts that well.

[MikalCarbine]

Mine holds the volts well, should I just leave the rails alone or lower em a bit

[Repoman]

Lower them towards spec.. you're not doing your system any favors with high PSU voltage. Just get as close to 12v as possible, overvolting is just as bad as undervolting.

edit: just tested a 145w 8 year old Compaq power supply for kick :D It was actually better than I expected, I thought it would have crazy jumps from like 11.7- 12.3. But it was relatively "stable" and only did crazy jumps from 11.95-12.15

Yes, 12.28v is probably not doing any damage, but why not lower it if it can be done easily? overvolting isn't giving any advantage.

BTW if my PSU fell even close to 11.4, or even 11.5/6 I would replace it in a heart beat, those ATX specs mean nothing.

On the PSU, Pin 10 is an ATX standard to have it be the 12v DC rail. Look it up, mine reads 3.41
You're checking pin 1, not 10. Check the other side ;)
Edit: I see you have a Powerstream PSU, so if you're checking on a 24-pin connector, you may be measuring pin 12 instead of 10......

Oh come on, your not still trying to argue that a pin on your psu output that should be 12V is actual 3.x??? Your system wouldnt boot/would crash instantly if that was the case......go back and check again :stick:

I know, I checked a dozen times, it's weird..

heheheh ::crawls back into hole:: :clap:

On a side note....

My rails are up to spec!

Analog measuring devices nearly always have much lower measuring error in comparison to digital devices, which have to convert the original signal into a digital one (that's where the error comes from most of the time, but not exclusivly). ;)


Completely false. Quantization error on a remotely modern ADCs are virtually zero compared to noise, etc in a typical system.

Digital is far better. Ever since I used a full digital scope I haven't been able to go back. Analoge is absolutely terrible for precision work. Though analoge meters can still be handy if you don't have a scope handy.

Just passing by and thouhg id post my 12v and 5v lines. load is dual prime
PSU in sig 12V idle 12.06 load 12.05-12.06
5v idle 5.10 load 5.08
id say pc and power cooling rocks
smart guardin read idle 11.77 load 11.71 for 12v and idle 5.02 load 4.99 for 5 v

I think what you may be overlooking is the possibility of the connector pins spreading causing a poor connection/volt drop at the connector itself. Never underestimate the value of the wiggle test of a connector while monitoring voltage.
