Gigabyte EX58-UD5/Extreme Discussion Thread

[The Water Dog]

This is maybe the wrong place to ask, i use a UD4P mobo now with a Pc power and cooling 1200w.
But if i touch the Atx24-cord a little the pc shut downs. Ithink its bad connection on the atx24 plug, but does someone knows what i have to do to fix it or should i ignore it?
I can lift the psu up and down and the atx24-cord, it only happen when the atx24-connection moves.

On most CPUs, 19x and 21x are more stable than 20x. Known i7 fact!

If its a D0, you should be able to go even lower on vcore and vtt. Three D0 chips that I have gone through could do 21x191 without any voltage change. Just turn turbo on, set BCLK to 191, set memory voltage to 1.65 and timings to stock manually and you are good to go!

You should be able to work with 1.25vcore for 4Ghz.

more stable yes but a difference of 0.1V or more? that just doesn't sound right at all

The new batches 39xx I saw can't do 4GHz with 1.25v, most of them are stable @ 1.28v ~ 1.30v+

If there is a bug in the intel microcode for 20x multi, it can do bizarre things and those instabilities will just manifest as needing more vcore to us overclockers.

Tonight I have been experimenting with some of the Beta Bios. I have noticed that the F8D UD5 Bios are working the best for me. I have a 4.20Ghz clock speed, with a BCLK of 200 and x21 cpu ratio. Uncore is running atr x18: 3600 mhz, and QPI is x36: 3600Mhz. I have RAM at 800Mhz 7-7-7-21 timings and Vcore of 1.328V in Cpu-z, something like 1.3625V in BIOS. I have VTT of 1.395V, DRAM of 1.680V, CPU PLL of 1.880V and IOH of 1.160V. This settings would not give anything stable with the F8e and the F7d, and F7c BIOS. I am not having any luck getting the chip over a base clock of 200 and being stable, nothing at all and even with the high voltage on vcore and vtt. I am not sure if the board is limiting me, since my MSi eclisple SLI would let me hit 4.45ghz+ with a base clock higher than 210.

quick question, will the chipset heatsinc be in the way of this sound card?

I mean will it fit?

yes it will fit , i have Auzen X-Fi™ Forte 7.1 which is longer than creative and it fit very fine

I just got the UD4p, and I guess this thread is the best place to put this...
3.3ghz easilly on stock cooling... max temps on the hottest core is under 80(79C after 2 hours of prime small fft, which is actually cooler than before, which ran 83C)
1.15vcore, I think I could go lower but I haven't tried yet.

http://valid.canardpc.com/show_oc.php?id=602172

I love the gigabyte x58 boards, it didn't take ANYTHING to overclock this(basically) except setting all the voltages, cranking bclk to 160, and making sure all the ratios and stuff were correct. I'm quite impressed with my first i7 computer.

Stock cooling? 3 week ban

Stock cooling? 3 week ban

Heh, I have a reason though, this is my first new rig in 2 years, so the newest cooler I have is the TT Big Typhoon... which is a 775 cooler. I'll be moving to water in this beast case in a week

[DarthRevan]

Stock cooler here too, I bought a Prolimatech Megahalem, but it was delievered to the wrong place and i´m still working together with the store to find it.


So WHICH SETTING IS GOOD FOR A 200 BCLK ?

[devsk]

So WHICH SETTING IS GOOD FOR A 200 BCLK ?

The one which works best with your mobo, cpu and memory combo!

Start low and go 3.6, 3.8, 4.0, 4.2.

Get to know your mobo, cpu and memory trio. Know what their limits are. Find what max vcore you can tolerate with your cooling. Find max BCLK with a low cpu multiplier.

Hi, I just bought a new system with the Gigabyte UD5 and the Corsair Dominator 6Gb Cl8 kit and a I7 920 D0 batch 3854B271.
Running Bios Version F7 which is the latest ..
Now the problem i am having is getting the ram stable @ 1600 Mhz. OCCT and LinX both crash on me in under 5 minutes when i run the ram @ 1600 mhz.
I have no problems with the ram set to 1333 Mhz and the machine seems to be stable even after 30 mins of OCCT or LinX.
I have tried with XMP enabled and disabled and it makes no difference at all to the stability at 1600 mhz. I still get crashes in under 5-6 mins. Nothing like this happens with the ram set to 1333mhz.
The settings i have for the ram are set manually to 1.65V and the Qpi to 1.36V and am not stable . I have NOT OVERCLOCKED the CPU at all.
Just trying to get the ram to run at 1600 mhz and i cant even seem to do that much.
My setting are Cl 8-8-8-24 2T @ 1600 mhz and i cant get stable.
Even tried QPI volts all the way up to 1.4V and still was not stable.
But what i did notice is that the UD5 is not picking up the correct timings for the Ram.
I would highly appreciate it if someone could give me the Sub Timings for my ram so that i can run it @ 1600mhz and get stable.
these are my current settings on the UD5 and i cant get stable with them..

Have checked the ram with memtest86+ and no errors so i dont think i have bad ram. And i dont think i have a bad Mobo either ,
because i can run the ram @1333 mhz stable on OCCT for 30 minutes no problem but i crash in under 5 minutes with my ram @ 1600 mhz

Thanks in advance for all the help guys and cheers
Hope i can get to the bottom of this...

Set Uncore Frequency to twice (2x) RAM multiplier (or 2x +1 if that fails).

[koc]

Need help please ,
what is the reason of this message ?

[Jonny Manc]

Don't know the technical term, but it means that your OC (whether mem, CPU or mobo) is not solid / stable, though it did seem to complete the run (odd).
Normal instability in Pi runs give that error DURING the run rather than at the end!?

[Bl0ss0m]

@Bluntsmoker and Toolius, this should help http://forum.corsair.com/v3/showthread.php?t=75932 also as mentioned before, have the Uncore set to 2 times the DRAM multiplier or 2 times + 1. ie 12x DRAM multi, Uncore should be set at 24 or 24+1

Personally I have my DRAM voltage set at 1.68 which EasyTune6 will say DRAM is at 1.648 and QPI/VTT set at 1.32.

I do wish to know where are the read points on the mobo for a multimeter.

Either vcore is low or all your cores are already loaded when you ran pi like running prime on 8 cores and then try to run pi also.

[Dahmer]

Well, after dropping my bclk to 191 & switching turbo back on to keep my 4 GHz it allowed me to drop my qpi/vtt to 1.31 (from 1.37) and vcore to 1.31 (from 1.4) and it's 1 hour OCCT and 1 hour linpack stable.

[koc]

So, its all about OC stability !
I will check the Bios setting and i will try again

Thank you guys for replies

[LiberalElephant]

Hey guys, I am too lazy to search this entire thread haha so I figured I would just ask. Is 12GB of RAM hampering overclocks on this board much? Is it dependent on the board or more on the chip itself? Thanks!

[koc]

I raised the Vcore from 1.2 to 1.218 , and that solved the problem

Hey there
thank you soo much for the help
have tried setting the uncore to 24+1 along with ram volts all the way up to 1.66v / QPI at 1.40and that didnt get me stable either..
i have a few doubts about the sub timings for the ram..
i set 8-8-8-21 @ 2T manually for each channel.. and XMP is OFF. XMP on makes no difference to stability for me...
Have you left all the other advanced DRAM settings on auto ?


would love it if someone with the Dominator CL8 kit to post their ram sub timings or tell me if they left the following settings on auto and still got stable @ 1600mhz under OCCT .

Basically do i have to adjust any of the following values to get stable @ 1600 mhz for the Corsair Dominator TR3X6G1600C8D Kit ?
I have a feeling its these Sub timings that are preventing me from running the ram stable @ 1600 mhz.
