DFI UT X58-T3EH8 continued - Part 2

[Ice009]

Mostly for Heavy SLI/Crossfire configs.

If you notice your 12V lane is very low under high loads, it might be best to connect them.

Most motherboard manufacturers have/had something like this... Sometimes it's a molex, sometimes it's a floppy power connector. DFI and MSI are only ones I know of that have this on their X58's though

Would I need to connect these if I'm going to run two GTX 275s in SLI?

[Sam_oslo]

I guess that 12v line can be useful for cards with big demand for volt, specially those dual_GPU cards. My GTX 295 has been running fine without it too, but I have connected it anyways, jut to stay on the safe side.

room temp aprox 33-35c
PWM temp at almost 100c
do you think i can pass Prime95 for maybe 3 hours?

This looks good, but keeping that PWM-temp at almost 100'C for 3 houser sounds a bit risky to me. I personally don't like to prime over 1 hour at these speeds, even with lower PWM-temp, anyways.

[pangingIII]

probably bad temp sensor on the PWM i'll have to find a way to check it out

anyways, the above voltage settings wouldn't do what i wanted it to do,
just got a reboot when i went out and came back.

then i try again with more CPU Core and VTT voltages...

BIOS set...
Vcore Droop Control： Disabled,
CPU VID: AUTO,
CPU VID Special Add: 106.85%,
Vdimm: 1.62,

[pangingIII]

i just tried enabling the Vcore Droop Control for the first time since i got this board.

Looking good with 12 RAM stability @4.4GHZ

I have always been using Vcore Droop, and that's what Intel recommends too.

[Peen]

hmmm works for 5 days straight no crashing now it's crashing again at idle ever 5min to 2hrs. Just freezing up even at different speeds with C1E off?? I haven't touched a damn thing either because it was finally not crashing...

Thinking my chip is maybe getting bad. I'm at 1.36v @ 4.2v and still crashes after a few hrs of prime and my load temps are only 70c. If I could RMA I would but I bought a retail off eBay and don't think I can. Frustrating as can be with all the random freezing/BSOD's

u need to eliminate this first

1. Ure own settings and reasoning for those settings
2. Cooling Limitation
3. PSU's limitation
4. then only hardware limitation.

reason for ure bsod's cause u have no empric reasoning on ure raise of component voltage.
whats ure bootup clock.. do u know whats the relevance of bootup clock and cmd vref voltage.. also do u know the relevance of vdimm to dqstb ref voltage and to dram speeds.also do u know whether its a dram chipset issue for dram limitation on the dfi.. aka elpida hyper vs bbse vs hcfo etc.

when do u raise the ioh analogue voltage?? and whats the reasoning of the ioh/ich voltage raise

ure thinking that raising voltage means stability.. for x58 and i7 and a digital pwm board like dfi it doesnt work like that .. ..
i have been watching ppl in lyn forums and the rest for dfi boards
always after more understanding on how the voltages work.. they end up with lowering voltages and having better stability. even on this thread.
y not stop posting empty spam reports.. and post after a week or two testing.
read praz settings.. and notice the difference in all his settings
read other ppl settings and do a comparison
read all eva's link.
understand thy board.

also prime95 25.9 x64 blend 5.4gb ..
theres a very unique way of understanding the cause of prime thread failures to the hardware component involved
based on the time of the failure.. the fft that failed etc..
understand this also ..

this is y in XS so many dont even post in the 8 hours prime stable thread. Linx for example is easy.
for x58's u cannot go further unless u have passed a 12 hours prime stable on different test enviroments
like in the case. cold boot, hot boot, wakeup boot etc.

again no offence but i think u better go back to square one instead of hitting 4.2ghz straight y not eliminate
any of ure so thought must be stable setting at lower speeds etc..tweak those first
and then work ure way up.

took a lot of ppl to get 2k c7 working like 2-3 months
and it was all down to setting the bootup bclk to 185. see u can miss some obvious things.

also give u another example of ppl and their wrong conclusions.

some ppl think 211x19 vs 200x20.. voltages for vcore and much less on the other..
after a lot of testing and reasoning on the voltages its not true..
this was the same thinking that happen on 775's when some said 400x10 vs 500x8 etc voltage.. it wasnt true then
for this board.. having the bsod " 2nd clock etc didnt receive signal etc etc" doesnt mean its vcore hint hint.
its just means some voltage that is proc relevant// aka vcore,vtt or dqstb is insufficient.
pwm temp is a very fine example to find which voltages is the cause of the failure
also dqstb and dram vref..
this are like skew settings . for voltages..
u do not raise all the channels/dimms equally.. test each stick. and single/dual/triple channel.
those who are familiar with 775's especially dfi x48 ddr3 and REX would be quite familiar to this tiresome way of fault finding

Sorry dude, they aren't empty "Spam" reports. I've been OC'ing for a very long time with lots of motherboards and rarely have any issues like this board. Most of voltages are stock and it has even crashed at stock settings. I've tried every single setting individually, all my ram with different timings etc, I'm familiar with what everything does.

This is just the first board I've had that won't crash while there is a load on it but does when sitting idle! It usually just freezes too no bsod. If it does BSOD, it's completely random. Doesn't help that I know I have a very poor chip (tested in another board also)

But thanks for trying to help

[kitfit1]

@Peen, i am shure that cstkl1 is not accusing you of posting "spam reports".

You really should have a good close read of his post though, because what he says is true. More often than not, getting a working 24/7 clock involves a lot of "thinking out of the box"

That said, you may have to just "bite the bullet", and dump the mobo for something else. I did, after running DFI's for years and years, and i don't regret it one little bit.
Whatever the problem is with the UT X58, it obviously is not going to be fixed with a bios release. It therefore is a basic mobo issue and will never be fixed for the peeps that suffer from the problem.

[v0dka]

Got this running on the little T3EH6.



HT = on
Vcore = 1.2375
VTT = 1.21
Dram = 1.6
IOH, PLL etc all at stock

This is stable in P95, WCG and every game I throw at it. Now, going higher than this ultimately results in BSOD or reboot regardless of voltages raised or HT turned off. So it isnt the heat either. Raised the multi to 24 for 4.2Ghz so I know the memory, uncore and QPI to be stable. No go. Same for 23 multi with memory clocked down and VTT raised a notch.

So a cpu related wall or just a board specific problem?

Spam report as ure saying ure end result without the beginning and middle.
thats a spam report for me in my context.

hmm freeze.. issues if u look on eva's link for prime stability on some of our journeys for the bootup clock 185 for 2kc7
before than freeze was the biggest issues.. and overvolting the ioh/ich.
having exact vcore also played a lot. overvolting vtt also causes freeze.
this however is totally elpida hyper related.

so in ure case i would look into that...

try earlier bios before 05/28.
but as kitfit1 said .. heck getting another board also will help.
ive had two classies and 4 dfi's and 2 r2e
after playing around with classies actually some of the dfi settings now started to make more sense. and having tried.. i might go back to r2e before heading out for a p55.

also on another note
"famous phrase in xs on comments " - " i have been overclocking for a long time"
and also take note this has nothing to do with dram timings. absolutely nothing as that is vdimm related.

[Peen]

Well I don't know what to tell you, I'm not going for max ram speeds since it doesnt seem to matter or even max any speeds atm. I got really nothing to report on except it worked fine for over a week no crashes. 1-800-reboot and it's on a crashing/freezing spree again. This board has been RMA'ed once. I do know my ram has known problems with this board and my CPU is very bad clocker so that doesn't help. btw it's not always freezes but the BSOD's are 100% random think have seen them all with this board. Might try to do an early bios again. Do you know what chips the OCZ Gold 1600 8-8-8 kits use?

Haha it may be a famous quote but I aint no noob at this. Even though this has been making me feel that way lately

edit: ya i tried all that bootup clock stuff at 185 anyways, but my ram can't get anywhere near those speeds really anyways. I don't need to touch the IOH voltage till 215 bclk. Haven't really tried past 215 much

never called u a noob.

hmm ure running 12gbs or 1600 C8's at 4.2ghz??
prob exist for 6gb only or only at 12gb??

well i know for sure from the transition from ddr2 to ddr3 .. all mobo is dram chipset dependent.

[Peen]

I know you didn't, kinda feel like one though usually good at figuring out stuff like this.

hmmm I have run 12gb 1600 c8-8-8-24-1n @ 4.2ghz. That was actually the least likely to freeze setting.

But dang, just thought I can't remember if 6gb freezes so I might try it for a few days and see

Oh yeah for clarification, it's not just a stresstest failing, its always the harder crashes like BSOD and reboot. Tried a few different BIOS with no result.

[radaja]

maybe someone can help.ive got an i7-920 DO 3849B018 and this board and ozc ddr3-1333lvA kit and the ram passes memtest86 at stock(optimized defaults)
but once im in windows and try to prime95(blend) it fails instantly,one thread after another.what could be the cause of it not being able to prime at stock settings?
its really starting to get me really upset.any help would be appreciated.thank you
Edit-i just threw in another kit of ram,corsair ddr3-1333 2x3GB kit and same thing.what can be the cause?is it the cpu or board?
please help
heres a screenshot

[Sam_oslo]

In these speeds, it is more likely related to RAM, than the CPU or MB (unless something is totally wrong with the CPU or the MB).

Do I see right that you are using vdimm=1.56v? In case you should use 1.65v and relax the timings (even more) to eliminate the RAM as the source of your problem. Your "other timings" on CPU-tweaker looks very "off" to me too.

[Peen]

Radaja, in my experience ram/chipset gets errors and CPU freezes/bsod's on this setup. Looks like you need more vdimm

[radaja]

this is set to optimized defaults.no OCing at all.
my speed in that SS is 1066Mhz.these are the
OZC 1333 low voltage (Animal kits).stock is
1333 cl7.the only thing weird in the SS to me is
the cpu at 2800Mhz,but i think thats turbo?i dont
think it should fail prime after loading optimized default
in the bios.that should be the most stable setting of all?

eh isnt ure twr suppose to be like 4 or 6... 8??

[batmang]

Finally nailed 4Ghz + turbo and power savings.

needed to connect the floppy power connector just under the PWM's to prevent my system from crapping out under sustained loads. This also completely nullified my vDroop with vDroop control disabled. (checked with DMM, voltage is solid as diamond now)
Currently 6hours into OCCT and already passed 10 LinX's and a HyperPI 32M

I'm going to try this today.

What floppy power connector? is it the one below the heatsink assembly near a fan connector?

[Peen]

Been running a few days at this speed no sudden weird crashes like 4.2ghz and 4.4ghz, 6gb vs 12gb made no difference


Btw what exactly is the difference between the IOH Analog voltage?

And I don't see how connecting the floppy would help with vdroop

[BieBiep]

Well, my 12v line fell below ATX spec (11.4xv or so) before I connected it. Now with the one connected, it stays @ 12.03v.

I had lots of crashes under load, (sometimes from GFX drivrs) so i'm supposing it was due to low voltage running trough my cards/mobo. All my voltage settings are the same as they used to be before the connection, but now it can pass long-term idling/OCCT'ing. So it did something...

[radaja]

well so far my venture into i7 has been miserable.
not liking it one bit.
still cant get it to run stable with stock settings.
instant failure in prime no matter what i do.
there has to be something seriously wrong with
either the cpu or board.
i am so mad right now.
why would it fail with memory running at 1066 speeds
i mean thats ddr2 speeds.it passes memtest86 without
errors,but as soon as im in windows and start prime95 blend
instant failure.
