DFI UT X58-T3EH8 continued - Part 2

[Praz]

I have a strange issue - I may run Prime several hours stable, but if I reboot PC speaker makes continious beeps and C1 error
What may it be?

A BIOS bug. When you get the C1 with constant beeping on reboot press and hold the power button till the board shuts down. Then press it again and the board should boot properly.

OT: @ PangingIII, are you Pangingjr from DH.net?


Ok back to some updates from the war front....

I have so far eliminated my 101 stop code (was definitely Vcore problem), and now got a 124 (time to tweak VTT), so I am making a ton of headway it seems...

If after the next 24hr test I don't get a BSOD, I will report back with some findings I have found with this board and my chip specifically, as well as the RAM. I cant say for sure it will coincide with anyone else here, but it might give some starting places to pinpoint what exactly is wrong with your setup.

I also would point some of you to this guide as well, it has some pretty good information regarding i7 platform and voltages - http://www.evga.com/forums/tm.asp?m=...09&mpage=1&key

Finally my D0 works well without any cold boot issue on my motherboard with new 6/18 BIOS. I am so glad that I have picked this motherboard

[Peen]

Well I got it, along with my new 850HX Corsair (had a 430W antec). Kinda a POS, squeels like a pig too underload. So far less stable then my MSI X58M and almost costs twice as much...

And what the hell is wrong with CPU-Z and this board? Reads anywhere from x1 multi to x21. When i reset cmos it works fine for a bit then it goes back to weirdness

Hi, is somebody having troubles with this mobo + Mushkin rams?

[ChaosAD]

Now i officially hate my pc. I set cpu/dram/vtt voltage in bios, enter vista, run 5 loops of linx. Restart pc, linx restart pc after 15-20 secs. I mean wtf is this

[rioja]

u should hate crap dominator i guess
try 9-9-9-30

[ChaosAD]

I test summer setup atm, 20x200 ht off. Dram 1.63v/vtt 1.33v idle, 1.36v load, Dominators at rated 8-8-8-24-2T. Why should i run them at C9?

[Peen]

I have a really annoying problem, it's rock stable but when I reboot it has a really hard time posting, the Diagnostic LED goes and then glitches out then keeps cycling booting. Eventually it will boot but keeps reseting itself in post. Anyone else have this problem?

here's some strange result of Everest bandwidth and latency test

what is NB? IOH?

[The-Fox]

pangingIII,
Your Everest results are way way out of the normal range.
Something funky going on there...

[Peen]

Are you guys running higher IOH voltage when in the 200bclk range? What about cpu pll? My tweaking time is limited atm...

[pangingIII]

what is NB? IOH?

yes, i meant IOH.

pangingIII,
Your Everest results are way way out of the normal range.

ya i know, but i have no idea what cause it, it's probably software bug?

it also happens to different board, ram and cpu...

[The Water Dog]

yeah, have to be a bug:P
i dont get these numbers on 2000, 7-7-7-20:P
Have you tried older versions?

[p2501]

I found that my problems may stem from setting the boot up baseclock. 21x200 (8-8-8-24 1600) runs fine (i.e. 25 LinX runs in the early and colder morning hours, didn't reboot to verify though, it's gotten too warm here) with that option set to auto, but if I set it to 185 to avoid the reboot at 26 issue, the very same setup bsods at the first LinX run. So what exactly changes with that bootup baseclock and how do I find out what AUTO defaults to?

Depending on cpu, lower bootup bclk depending how far from target bclk will require more cpu vtt at a certain point. i.e.

200bclk target
170bclk bootup more cpu vtt than 185bclk bootup.

The optimal bootup bclk below target bclk will vary from cas7 vs cas8 vs cas9 memory settings too. For example at 200bclk 185bclk bootup cas7 might be optimally but for cas8 might be a 190-195bclk bootup bclk.

Auto bootup is same as target bclk AFAIK. As you reduce bootup bclk more, RTL values get tighter for more performance hence need for more cpu vtt. Optimal bootup bclk will allow lower cpu vtt though but still cpu dependent.

[p2501]

So it really was a problem of improper subtimings, i.e. RTL values. Thanks, that was concise.

It seems I am a prime example of someone messing with settings I don't really know about and wondering afterwards why it's not stable. I will go and lap the hell out of my chip now and maybe later in the night test again if cas7 is possible with the proper boot up baseclock. Or maybe on auto. ^^;

I hope this 'one boot stable, next boot unstable' isn't coming back.

Now with the 6/19 bios, and the boot up base clock in auto i'm stable after a shutdown too, i should try to reboot. Let me know if you have new infos

Remember if you got D0 and use Chaos`s template the CPU VID Control and CPU VTT Voltage is lower=)

I can't get my 4850x2 vidcard to work on this board, not sure if its dead or not...http://www.xtremesystems.org/forums/...d.php?t=228194

[ChaosAD]

ChaosMinionX which bios do u use? Have you tried running Linx on these settings?

[Peen]

ok getting very pissed off...did anyone have any problems getting a single card (4850x2, 4870x2) getting crossfire enabled? Have tried 2 fresh installs on vista and Win7...4 different drivers.

my single card 4850x2 keeps only showing as 1 4850x2. I don't have anymore PCIE boards to test it in so not sure if its the board or not because it used to work! Have tried 4 different bios too
