Official DFI LanParty UT X38-T2R(and LT) Discussion/Review/Overclock/Guide Thread

[PhilDoc]

what are you using for cpu cooling?...water?

I'm using a TRUE with 2 150 cfm Deltas. I run them on a fan controller so I dont have to listen to the noise all the time, lol. Hopefully, I can find a way to mount my SS and try that.

Anyway, just tried my first GTL adjustments. Eva's 99/99/99. Not too bad, gave me another 30 mhz, been priming for an hour. Now, if I can just learn how to tweek the memory. This board has one complex bios, I love it.

explains the good overclock but also, it looks like your cpu is a good chip...BTW, what is your VID for that chip?

the DFI LT does offer mucho settings!!..BUT...i like to have simplicity...it is the reason i returned to my IP35 Pro...i was getting the exact same overclock with air (TRUE)...big difference for the DFI was not having vdroop, and you had three 16x PCIe slots; two of them giving full 16x speed....layout was also excellent!

Hey folks,

I'm looking for a new mobo because my Abit IX38 couldn't cope with my Q6600's excessive power need
Will I run into any trouble with this DFI and a 4Ghz+ overclock? Will be using a SS unit and plan on running folding 24/7 so I need a sturdy mobo that won't go down easily.
What about coldbug/readout of negative temps anyway?

cheers

I got the Abit board in X'mas and was quite happy with it running at 3.7 water cooled, because the very same chip hit a fsb wall of 335 on the P5W DH.
A couple of weeks gone by and all of a sudden the machine kept rebooting itself and I was shock to see 1 of the PWM readouts on uGuru showed a soaring 150 C under load.
I took a chance with this DFI board last week and so far I'm quite pleased with it. It runs a bit cooler and takes even less voltage to reach a higher OC.
But hey I only have it for a week though and It's too early to tell.
However, IMHO the so-called Smart Guardian is a joke comparing to uGuru, just my 2 cents worth.....

[Ace-a-Rue]

yeah, nothing can really compare to Abit's Uguru program.

Yep, looks like I've gotten lucky with this chip. Hopefully, as I get this board figured out, it'll get better. Right now the VID is 1.1125v.

I love to tweak, which is one of the reasons I got this board. It may not have enough fsb if I go SS though. Maybe a bios change will help. The Abit's a great board and would have been at the top of my list, but I wanted to play with some crossfire later.

Excellent job as usual Eva. I'm using the DFI X38, e8400, and the Ballistix 8500. I was wondering if I could get your bios settings you used for memory. If you could it would really help me in trying to figure things out.

Just flashed to 1/11 official bios myself more tests to come - current bios settings can be found at http://i4memory.com/showthread.php?t=5400

for memory key is adequate NB volts and clock fine delay tweaking http://i4memory.com/showthread.php?t=4743

Should I be leaving my CPU VID on auto and only up the CPU VVT? I cant get my Q6600GO past 3.6ghz even with CPU VVT at 1.57

hi
i have the same problem like you

could somebody to answer?

[Ace-a-Rue]

hi

once you go above 1.15 on the CPU VTT, you have to enable and then adjust the CPU GTLREF...low CPU VTT should start around with '95' setting and as you increase the cpu vtt, you will need to increase the CPU GTLREF.

go to eva's link...his guide should help you through it.

Where can I read more about that? I tried i4 but didn't see any specific post about it (99/99/99).

[Bikerz]

Anyone got audio working on XP 32 bit?

80/80/80 gives extra 10mhz

My E8500 aircooled with intel box.

DFI X38 : Max boot 520 / screen 540
Maximus Extreme : Max boot 550 / screen 575
P5K : Boot @ 600*6 ... not tried max because it s an mobo at work. (but orderd one ...)

anyone try unsoldering the X38 from one high fsb board and putting it on another LOL J/K

OR maybe intel needs to make NB/MCH a removable socket like a cpu and sell NB/MCH by themselves so we can test different NB cores on the same board

yes and GPU also

Tx Eva, but this only apply to the e8400 or to Quads also?

[eva2000]

yeah then we can hunt for NB and GPU batch dates hehe

it's totally cpu dependent, 2x E8400 might have different GTL ref sweat spots heh

Well, I have my system wPrime 1024m Stable with my q6600 at 3.7 ghz. It was not easy though. I really thought I could get more our of the CPU for the 1.5 V I am dumping in. My 2 hottest cores are at 60 C under load, so I feel like there is room left to play. Electro-migration FTW?

Something is wrong, I can get 4052Mhz (452fsb) wPrime, 32mSpi and 3dMarks stable with low volts on my Q6600 in this board.

Can you create a siggy?

[Origin_Unknown]

^^ each cpu is different...

better yet, let see a screen of your "LOW" volts. my guess is you are close to 1.5-1.6 on the northbridge, and prob +1.4v cpu vtt.......and in your sig you are showing 1.49, which is not much lower at than 1.5, which is a very small variation between cpu's.


A thought, not necessarily related to the above posts.


A lot of instabilities can be attributed to higher than needed voltages. I think some people around just pick random numbers from the air or use other members settings, when it is best to set you own from proper testing. You need to isolate the memory subsytem and the cpu from each other to see what is causing the stability issues.

1. Test memory subsystem

a: It is best to start at your chosen/desired FSB with the lowest multi that will give you the closest to your stock speed. Set your memory using a 1:1 divider. Start at stock voltages, increasing your mch voltage slowly until stable (prime95 blend ~ an hour).

b: Then after that is stable you can adjust dividers and timings. Bringing up your memory speed and possibly tighter timings. Slowly increasing voltages on the mch again until stable (again prime95 blend ~ an hour). If you set you memory out of spec you will also need to raise your ddr voltage.

After you reach this point you know you memory subsystem is stable. This should not change with the adjustment of the cpu multi.

2. Test Cpu

a. raise your multi up until you reach your desired speed. then slowly increase your cpu voltage until stable (prime95 small fft ~ an hour).


If you have not followed these steps, how can anyone know why another persons system isn't stable?

70% OC in the Q6600 (to achieve 4050Mhz) with a 0.2v increase in vCore is VERY low if we are speaking the same language...

And that's what I'm talking about when I said 'low' volts. There is no such thing as miracles, to achieve 70% above the specs you need to keep the normal energy flow to your cores.

Dunno what your problems are but this screen I took without any tweaks on volts and with GTL etc settings disabled, thus it has plenty of room for lowering vcore, vnb and vtt volts:

[crazyea]

I am not personally experiencing any problems, I just think that some peoples issues could be attributed to poor testing methods.

Without even seeing you screens I was pretty close. 1.5v would be absolute max I'd put on a g0 quad, and i wouldn't do it for 24/7 use either. Too risky imho.

At stock my q6600 g0 is around 1.24v at stock, 1.216 FSBv, ~1.3 NBv. Based on my quad those voltages are quite a bit higher. I wouldn't say Low at all.

While your o/c is very good, and the voltages are relatively low "for the achievement", they are not low in the scheme of things relative to a g0 quad. For me, these voltages are more along the lines of moderate-high for every day use. I just wouldn't do it. To each his own I guess.

Are these 8hrs+ prime stable or are you along the lines of 30mins stable is good enough?

[C-N]

1.5v would be absolute max I'd put on a g0 quad, and i wouldn't do it for 24/7 use either. Too risky imho.

Each to there own like you said but 1.5v is the maximum limit Intel recommend on the stock cooler so theoretically perfectly safe & made even more so with upgraded cooling like we all use.

[crazyea]

Maybe so, but it is not "low". You said it your self "maximum limit", so even with after market cooling it is at the "high" end of things. This doesn even take into accoutn any voltage spikes that can and may happen.

This is my point.

[zanzabar]

u guys should stop quoting gtl settings without voltage they are in a percentage relationship of what u need with the voltage and in numerical form so that u get fin tweaks so saying that 99 or 80 worked is meaningless without the reference voltage for that gtl that u used
