DFI UT X58-T3EH8 continued - Part 2

[batmang]

LoL!

just because you have to input most settings manually, where the Giga automagically disables/enables some things (which you might even want, like power saving functions!). Doesn't mean this board is a headache!

You just have to actually KNOW what the hell you're doing before you do something like enable/disable C1E or try to lock the multi to 21



Noticed something strange about PWM temps btw:
Sometimes the more stable your CPU is at a certain frequency, the lower your PWM temps are.
I was running LinX yesterday and choosing a LOWER voltage actually meant HIGHER pwm temps.

I'm supposing that this is due to the processor asking for more, and the PWM trying to keep up... or it might be that some voltage settings are just a tad "harder" to pull of than others.
It seems that my board particularly likes 1.344v or 1.360v since sometimes it just keeps drooping to those 2 volts, even though i selected 2 settings higher than the last time it drooped to 1.36.

I know, hah! This board is a great board but lets be honest, it can be pretty frustrating getting the right settings the board likes. Because all boards like different voltages/settings, the T3EH8 can be a bit of a pain at times. Overall though, its a great board as long as you can be patient and utilize the features it has. I still can't get anything above 4.0 to be 100% stable but I know its possible, just haven't had enough tinkering time. I've stuck to 3.6 HT @ 1.16v for 24/7 use and 4.2-4.3GHz HT @ 1.3+v for suicide runs. I like my memory speeds at 3.6 :P

no offense
but

if u say dfi x58 UT/DK is hard
then any 775 mobo must have been nerve recking for ya
asus REX,COmmando,M2f, DFI p35-x48, etc etc etc all must have just blown u away... literally. hospitalized i guess.

i7 x58's are like overclocking for noobie friendly.
it just cant get easier than this.


heck 50% overclock with minimal voltage changes.

this mobo is just so easy.. no skewing to worry about and all the dram skews are taken care off with the IMC and the way dfi implemented it via bootup clocks..

and this is the only mobo other than the under performed classified that
runs high percentage overclocks at almost stock voltages. aka no degrading issues like the famous gaygay mobos that in the end,.. ends up in a lot of ppl garbage bin after a year.


this is what happens when overclocking goes mainstream.
next ppl will be demanding intel/amd for overclocking headrooms.

And most of the times. People jsut have to face the fact that they actually have a bad clocking i7, since most people seem to forget around here that NOT every i7 920 can actually get 4Ghz with turbo for 4.2.

Most(if not all if you only look @D0's) do 191x21. But after that it's hit and miss.

[OnDborder]

I'm very happy with this one, it has been running on DFI @1688HMZ 7-8-7-20 1.65v with great performance and stability for 24/7 use. I have had several benches/tests which you can find earlier in this thread.

Thanks Sam.
I'll look them up.
In this thread and/or pt. 1 too?

No offense taken. I'm not overwhelmed by this board or x58, I'm just having a hard time getting above 4.0 (stable), which isn't that uncommon with 39+ batches. I've been overclocking for a very long time, since AMD K6-II days. I never had a 775 setup so I have no clue how easy or hard it was with those boards. I was one of the AMD fans that went with the Spider platform, I had a Phenom 9600+ 2.3GHz and the MSI K9A2 790FX Platinum, what a huge mistake. Overclocking Phenom's (I & II) are much harder than i7, I agree i7's are cake to OC. I was able to get 3.8GHz out of my Phenom II 920 2.8GHz which was much higher than the average Phenom II OC. I'm just greedy with my i7 and want 4.2, but if I get that I'll want 4.3 or 4.4, etc.

And most of the times. People jsut have to face the fact that they actually have a bad clocking i7, since most people seem to forget around here that NOT every i7 920 can actually get 4Ghz with turbo for 4.2.

Most(if not all if you only look @D0's) do 191x21. But after that it's hit and miss.

I need to learn to face this fact.

[ChaosMinionX]

I found an interesting thing that when I manually set the various RAM subtimings and such my results within CPU Tweaker for channel A differ from that of channel B/C (B/C happen to be identical, but there is a large difference in whats actually set for channel A)

BIOS 7/24 - Will post some screens if I can figure it out, seems to be on tRTP and tWTP.

Exactly, this motherboard is the definition of "easy". Mine was just that, easy!

[ecidious]

You'll always want more but you probably won't notice the difference outside of benchmarks. Mine will do 4.2GHz with high vcore but I run it at 3.8GHz and get the same FPS but my room is 5° cooler, and that's about the only difference I've noticed.

[Peen]

Well I got more board back, it works. Prime it for 10min (still squeals like a pig!) to make sure its good then it locks up idle again! haha

Anyways, I got a new AMD rig to play with CPU+RAM+Mobo for 150. It's a sweet little comp overclocks easy doesn't do anything weird! might sell the i7 and just use this since, well it just freakin works!

[Peen]

Son of a @)#%@#

Well the board works after RMA, but now it F'ing drops .1v CPU under load....WTF is this??? Never again with DFI. Instant crash.

Good repair job idiots!!

Have you enabled VDROOP control in the BIOS?
Mine drops 0.032V (according to CPU-Z) with it enabled (from 1.408 to 1.376).

[pangingIII]

i don't think i have any complaint about this board but the high PWM temps.
tried adding fan but didn't seem to help much on this one,
my old board for some reason seems to have much better PWM temp.


4GHz overclock with pretty much all stock volts
true with 1x 2000 rpm fan, room temp at 27c.


BIOS set...
PPM function disabled (this also disabled Turbo Mode, EIST and CxE functions in bios), Vdroop control disabled
CPU VID Auto + 105.90%,
Vdimm 1.62,
IOH 1.10, CPU VTT 1.21, the rest are also at stock volts.

BIOS hardware monitor shows...
Vcore 1.18,
Vdimm 1.60,
IOH 1.10
CPU VTT 1.25

Everest hardware monitoring software...
Vcore at load 1.20, no load 1.18,
Vdimm 1.60,
IOH 1.10,
CPU VTT at load 1.232, no load 1.216

[BieBiep]

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

Ambients are 28°c, Radiator/Case temps are mostly around 30°c. Unnaturally sunny for this time of year and my room has constant sunlight, so its really cooking in here.

Core temps go up to 77°C under LinX with a Swiftech GTZ, bah... I wasn't very lucky with my Xeon (3851A), it's hot and it needs a lot of vCore. Decent VTT and memcontroller though.
PWM temps go up to 78°C under LinX load with my NB wc'ed by a EK-MAX-Acetal. (not too happy bout those, but meh, rated up to 105 so anything under 90 that's stable is good for me :p)

=> hot pwm's are also due to the 2x8800GTX right below them. Their PCB's radiate heat like there is no tomorrow and the backplates are constantly @ 55°c with nvidia's new "DirectCompute" drivers... I don't know WHAT they're doing, but they're heating up my case significantly...

I'm thinking about swapping out the GTZ for a Heatkiller LC. It's way less restrictive and also offers better temps, that might bring down my pwm temps too then due to better flow trough my NB-block... But meh, we'll see

[jcool]

I recently had trouble with 3D06 and a 920 clocked at 191x21 with turbo enabled. With bios 0619, there is no real control over turbo mode, and instead of going only 1 step up it does 2 when only 1-2 cores are loaded --> jump to 4,2Ghz and freeze during Deep Freeze. Really annoying issue, had to disable the turbo and run it at 200x20 which needs slightly more Vcore but doesn't freeze (better for the customer lol).

[Sam_oslo]

No problems with turbo here, x21 is working just fine after BIOS 07/24

Moving up to @4.3GHZ(205x21) 1.26v
12GB RAM, 6GB OCZ 1333MHZ CL7 + 6GB Corsair 1600MHz CL7, running @1266MHZ 6-7-6-22 1.65v
VVT=1.21v, NB Core=1.12v (both BIOS set)
Still going strong with x18 Uncore

w3520 @4.3GHZ(205x21) 1.26v, 12GB 1266MHZ 6-7-6-22 1.65v, HyperPi32M Stable



The read-bandwidth has dropped by about 3k to 17k-read and 44ns latency (vs 20k-read and 41ns of 6GB Corsair) but I'm still having a hard to track the effect of "slow RAM" on my real-life applications. I guess both of them are overkill anyways.
Just started experimenting with and 12GB, and I may go back to 6GB. Just made a 2.5GB RAMdisk and I have to see is I can put it in good use.
Even tho I haven't tested the total stability of @4.3GHZ for 24/7 yet, but it is running so smooth that I may get used to it .

Yeah this board works fine for me too, the only problem is my cpu

I have been getting some freeze 3-5 minutes into prime-smalFFT @4.3(21x205) 1.26v, too. As far as i can tell, the Uncore and RAM are running stable (any RAM/QPI stress tests i have tried is passing). I'm still testing and can't conclude yet, but it seams to be some issue with stability of the Core with x21 multi. I have tried to add more Vcore, but it doesn't seams to be helping (at least withing those limits of Vcore I expected it to stabilize).

I vent back to @4.2GHZ(210x20) 1.24v and Prime small-FFT is running without any problem for 20 min now, and still is running in the background ... Anybody else having a similar experience?

EDIT:
have been testing more ... but it's geeing late. Going back to x20 for now, until I find more about the x21 stability.

Wow doing very nicely there mate

[Peen]

You got a nice chip there Sam.

I need 1.344 almost 1.36 to get 4.2ghz Stable. But I did manage to get my OCZ Gold (12GB) stable at 1600mhz 8-8-8-24. 7-24 bios is the only one that can do it with 4000mhz Uncore. Needed 1.69vdimm along with 1.36vtt to get the 12gb stable at 1600mhz. So I figured might as well stick it to 4000mhz Uncore too since it needs about that vtt anyways.

I'm having some fun playing with my new Gigabyte + Athlon II X2 cheap HTPC rig for now! Awesome little AMD

EDIT: Btw have you guys heard of this W3550? Same price as 3540

[Sam_oslo]

Wow doing very nicely there mate

Thanks man .. trying

You got a nice chip there Sam.

Yes it is getting better

Got the Core stable too, at least pass the "kill zone". I found that my new "fancy" gadget (Rivatuner Sidebar Gadget 2.0) was making the desktop unstable and crashing it after 2-3 minute into prime95.

But it didn't solve all the problems, i was still getting crash in the "usuall kill zone" and I had too to add "one notch" to VVT, NB, and 2 to Vcore. It ended up with VVT=1.23v and NB Core=1.15v (both BIOS set).
The Vcore=1.28v(Load) was a bit higher than my expectations but it didn't affect the Core-temp as much as I was fearing .

12MB RAM + "1 notch extra VVT" was enough to push the System-temp to 61'C, but this is just 1'C in the "red" and I will see if I can increase the RPM on NB-fan without too much noise.

W3520 @4.3GHZ(205x21) 1.28v 1 hour Prime stable

[pangingIII]

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

Different issue mate. As long as you're fully loaded, the mult won't jump to 22x.
I could pass 24h of prime or LinX with my 191x21 setting, but even 1 run of 3D06 froze the system (because 3D06 sucks so bad that it only uses 1-2 CPU cores in all GFX tests)

[Ice009]

I wanted to ask this question before, but forgot all about it. Do people have those Floppy Power connectors connected on their boards? Do other Motherboards have these or is this a DFI thing?

I wanted to ask this question before, but forgot all about it. Do people have those Floppy Power connectors connected on their boards? Do other Motherboards have these or is this a DFI thing?

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
