problems with socket 939-a64 setup
 

setup : superflower 520 watt psu, fx53, one sata 80mb, a8v, x800xtpe, one cdrom, no other peripherals

random freezes going blackscreen needing reboot, sometimes I lose internet connection after some minutes too.

asus probe shows me 11.18 on the +12v! is this the problem?
how the hell can a 520 watt psu have problems with this small unoverclocked setup?

don't know if it's the problem, but superflower sometimes does have low 12v rails. Mine is 11.5V but with a lot more connected. Try another psu and are all the drivers and biosses up to date?

drivers are ok , board is rev2, I ain't changing the bios as of yet...

prolly the PSU , try to replace.

PSU problem Doc, get another one.
check bios for that +12v

11.80 in bios :(
not the psu in my humble opinion.

networking is weird...
sometimes it works, sometimes it doesn't

I updated to bios 1.006. Hopefully everythin,g is solved now

so...
latest nic drivers, latest via drivers, latest bios, latest everything.
every now and then i-net stops working.

haven't had any more crashes so that's a plus :)

read his reply? http://www.madshrimps.be/forums/show...3039#post73039

:p

:nutkick:

Motherboard power circuit, MOSFETS.

what can I do? I have two fans exclusively aimed at the mobo?
could putting it in the vapo and thus taking away cpuheat change that?

11.80 in BIOS is volt-lines at idle
check them in windows when under load

Sticks some ram sinks there may stabilize voltage fluctuation a bit; cheap insurance after you check voltage in windows under load as Jmke said.

voltage under load = 11.20 as I said in first post.

I hate to say this Doc.

I have a 500 Watts PSU sitting here; and I don't even want to say the name; but it weights about 3 Lbs. It gives out 11.13 volt without OCing at idle.

I'm saving it for my next trip to the rifle range.

Mother board giving low voltage at times; but never this low based on my own experience, only.

------------------------------------------------------

By the way, double check with a multimeter if you have one.

wow! sorry, must have overread that, that's way too low, this EXPLAINS all the reboot problems :/

Calantak , about the inet that is acting weird , do you have SP2 ?

I have two systems running on SP2; not the problem.

Switch PSU and see what happens next.

yeah but doesn't mean it's compatible with everyones hardware/software

Try using the big power connector on the mobo and the little square one... Some persons on an amd setup got way better 12v readings then just using the big one alone. Give it a shot(if not done already)

TTGI 450 Watts - This guy actually is dead on in 12/3.3/5 volt rails using Multi-meter while system is running. Yet, the mother board circuit is under load, where Windows and BIOS both report lower voltage:

Multi-meter (hook up under windows) vs MBM/Windows/BIOS

12.15 vs 11.67
3.31 vs 3.18
5.19 vs 4.89

I put this PSU to another system

12.15 vs 12.24
3.31 vs 3.4
5.19 vs 5.20

I do have another PSU 500 Watts that is so bad; shooting it is my only way to express my gratitude to the maker.

Sorry to say, the only PSUs I will spend money on without being screwed first are;

OCZ
PCcooling
Cooler Master

May be with ?
Antec
Thermaltake

As for motherboard; I will check the voltage via BIOS using a known good PSU; without a second thought I will RMA the sucker if the voltage is on the low side. This way, I don't waste my time.

so that's a lot of different approaches.
first approach for me : not spending any more money (vapo/fx53-asus xt-pe, 1 gig of ram, a (now dead raptor) two maxtors in
1and a 1/2 month is a bit over the edge I think.

the fact is.
it didn't crash under load or sth (prime), it crashed randomly.

the fact is also that this psu was doing an 80w pelt, a 9800xt, 3 hdd, lots of fans and a friggin 4 ghz p4, never rebooting once, putting it in a fx53 default without any peripherals unoverclocked with no pelt should NOT give this problem, giving perfect rails on anything I threw at it beforehand 12 flat and 5 flat.

ah
pcs suck :)

if the problem persists then, it's hammertime.

fact is that the network also fell out tens of times on this mobo...
isn't that where the problem lies then?

fact or no facts 11.20v is too low...

what (directly available) psu would you advise for me?
antec?
ocz?

Or, the motherboard is giving low voltage.

My preference is OCZ; reason = they have to service the hell out of new customers.

if the problem persists, both the reboots and the lan-problems, wouldn't the smarter choice not be to rma the motherboard?
because the psu has served me well and shown its worth in the past, the mobo has NOT. and the marvell-lan problems have been described... maybe switching it with an msi would solve the problems...

I will have no second thought.;)

listen...
I was planning to get me an antec truecontrol 550 anyway, so I did.
I will recheck this setup next weekend with the antec, do a complete reinstall with all drivers, and I will advise all present hardware to do their job.
If it still doesn't work I will rma the motherboard.

does anybody know what is safe voltage for a hypercooled fx-53 processor?
and what is that Vfid voltage?

btw, since mbm is dead, what programs are you guys using nowadays for cputemp?

MBM5 still works fine.

what settings do I choose on a a8v deluxe? :)
I get 15.89 volts on the +12v of which bios says 11.92...

But the voltage thing is the most important for me...

Remove MBM completely and reinstall; hopefully your Motherboard will be showing up on the list. Two of my Asus P4 boards will give over 15V on 12v rail until I choose P4P800 from the table during install.

or just go into Start -> Mbm5 folder and choose "config wizard" :)

It sounds much easier than my alternative.;)

my mobo is not on the list, that's the problem...

change the sensor in the MBM5 config :)

isn't there monitoring soft on the Asus CD ? PC Probe or something like that

I've changed the probes on mbm, I'm no moron, I've been into mbm since 4-5 years, pre-wizard stage. simply doesn't turn out right
asus probe doesn't work with subzero temps.

1.55 volts was stable at 14*200. still saying at default ram for now,
I'll set it at 1.7 this weekend, and stay there, and look how high it can go this way, hoping for 15*200, if that works, I'll never touch it again until I replace it :)
if it doesn't, I'll stay at 14* and try upping fsb.

14*200 = 2800 Mhz is really nice on that voltage

disable temp monitoring, check the voltage lines... :hello:
