DFI UT X58-T3EH8 continued - Part 2

[StimulatedBoy]

What do you mean by "no go"? Does 16 & 19 require more voltage than for example 05/08?

BIOS 06/16 and 06/19 does not work at all on my system above 4.3 something no matter what voltages or adjustments I make. 04/28 and 05/08 on the other hand gives me 4,96 GHz 24/7 without any hassle at all (160 * 31 - vcore 1,425 -1,4 VTT - All set in BIOS).

So i'm the only one that is still having problems, fine -.- i think i'm gonna change the PSU

[p2501]

Just to clear that up, the one and only problem you have is unstability when loading a profile but when values are entered manually it's all fine?

No. I still lose stability after reboot. Gonna change the PSU and try again

I don't think that this comes from your PSU. Did you download CPU-Tweaker? I'd carefully monitor all your timings before and after reboot with this to see which settings are actually changing. This is definitely related to volts or timings, if it was your PSU which is unstable you would have insta-reboots or shutdowns or the likes.

If you're stable in one run, screenshot CPU-Tweaker then reboot and compare.

i had similar after-rebooting issue on 2 board already - dfi and foxconn, with corsair and ocz ram

so i think now that there is no any issue with board itself, just overclock come to limit
lose stability after reboot is a myth
just lower overclock a little and you ll be fine
or get another cpu

Ok, i'll do this tomorrow

@Rioja, isn't a cpu problem, i was stable @4ghz with a Giga UD5, and now i'm testing 3.8ghz

EDIT: Latencies did not change. Could it be a PWM temp problem?

Note: 0619 is now official BIOS~

Why do you tend to think that it could be related to PWMs? Are they running that hot? Keep in mind that some of these digital VRMs are rated up to 100 or 125 degrees C, so even if you're running 80+°C you're still way in the green. What I didn't ask yet, are you load testing with LinX or Prime?

(looked it up, the 2 cooper bussman controllers (the ones with cpl-4-50 written on them) themselfes are rated for 125°C, still searching for volterra ratings)
Edit: Volterras are VT1165SF I believe.

Linx (or OCCT) the problem is that i get error in max 10 secs after the reboot

[p2501]

10secs after start of POST or 10secs after Windoze login? For that it would also be interesting to know what you're trying to get stable here? Clock with or without turbo?

10secs after start of OCCT test

I've tried a lot of config. The most stable seems to be 3.8ghz with ram @2000mhz, but it needs vpi 1.45v, and it's too much

Now i'm testing 180x20 with rams @1800mhz, but nothing to do

[ChaosMinionX]

So I am still getting occasional BSODs, I think this board needs a better BIOS still.... It passes LinX/ Prime95/ HyperPi etc, but randomly will get a 124 BSOD which is the VTT presumably which I have at 1.42v

[p2501]

10secs after start of OCCT test

One setting works. Then you reboot. Now the same setting errors out 10 secs into OCCT, also your temps are all fine I presume (what are they like btw?). You already changed memory. I'm sorry, but that sounds as if something just isn't right with your oc and since you tried around alot it sometimes helps to start again from zero, meaning setting your multi to like 15, set you bclk to 180, loose memory settings. Get your bclk in steps to what you want it to be (5MHz steps until 200, then smaller). When target bclk is reached, raise the multi until your target is reached. Last, get your mem up to speed. With what ever you end up then, should be stable.

I'd try reflashing your favourite BIOS, clear everything and start again, not using any presets.

Unfortunately it's the board. About the only thing that can be done is to decrease the overclock till it no longer happens.

It's the same thing like what was described on DFI like that one guy here said? If so, when is DFI going to do something about this incompatibility between D0 i7/Xeon and the board? Like a new BIOS? I was just thinking that what I wrote in #614 might be applicable since someone in this very thread said something about his board "settling in" after some long LinX runs, resulting in slightly higher volts needed. Thats why I proposed that for now one thing Razer(x) could do was to start again.

Starting over will most likely work. But with the UT boards that have these issues this becomes an endless cycle. Don't know when we might see a new BIOS. If I receive something that has a glimmer of hope fixing these issues I will set the board back up and test it.

well this voltage issue is very true but the margin is very small
some day my proc works great at 1.28v 4.3ghz prime95/linx stable at 12/7 hours runs vtt 1.42 for 2050 Cl7
some days it needs 1.29v 4.3ghz vtt at 1.44..

so i just run it at the higher voltage.
but its weird

confirmed with dmm many times over.
but the errors i get in prime would be one thread error and linx with give a error.
no bsod's

[Razer(x)]

Ok the cpu seems to be stable at 180x20. Now the problem is the ram. I'll test everything tomorrow, gotta go

[Sam_oslo]

You guys who having these strange problems, any of you have been pushing too much VVT (>1.35v) or too much Vdimm (>1.65v) on your 24/7 OC?

Can it be an early signs of degradation?

[p2501]

Can it be an early signs of degradation?

Naw, I don't think so. I'm running 1.42 vtt, 1.66 vdimm and 1.32 vcore (just 0.04 above my stock load vcore) with no issues at all, other people are running even higher volts. Some boards just seem to have these issues. Also I don't think I've heard of degradation with i7 CPUs, either they die (wrong VTT-VDimm) or they run.

Board degradation, maybe. See cstkl1's post. The thing I don't get here that DFI must have come to notice that there's a problem with certain combinations but there's no BIOS fixing this.

On a completely unrelated subject, anyone notice there just no specsheet out there on VT1165SF? I'm just interested on how hot they are rated to run.

I couldn't find max-temp for VT1165SF either, but SG is "red" and clear: Keep your System-temp under 60'C. Don't run in "red" for long period of time

I haven't heard about i7-degrading either, at east before reeding this tread. 1.32v Vcore is fine (as long as you can keep it cool), but I wouldn't dare to run 1.42 vtt, 1.66 Vdimm on my 24/7 OC and be sure that "nothing" would "degrade" over time. Even tho it could be OK for benching/testing (shorter time).

My setup seams to be "upgrading" , and run at higher OC with the same voltages after a few weeks with low-volt 24/7 action 1.15/1.23/1.65v (Vcore/VVT/Vdimm, Load)

not degradation

its random..

also take note all test is using prime95 blend 5.4gb 12 hours min and linx min run is 100.

if 2-4 hours no prob .

What if I passed both of those multiple times and after rebooting? Yet still from time to time I get BSODs with code 124?

[Razer(x)]

No problems running the cpu @180x20 with mem@ 1440mhz (auto latencies). Gonna try 1800mhz
