I7 920 with x58-ud3r weird stability issues...

[dbee]

hello, i have been a long a time reader and am sure i have read just about everything i could possibly squeeze into my head regarding the specific components and settings of my setup. Heres my problem, i can get a solid stable overclock to 3.465 ghz with only 1.21 cpu voltage. Thats a BCLK of 165 with 21x multi. As soon as i up the BCLK just one point to 166, i crash instantly upon opening Prime 95. It is not a heat issue, With HT on, i my max core temp is 67 degrees C. Giving it a small voltage bump , like 1 or 2 notches brings me enough to raise my BCLK to 172. Same temps. I have also tried setting the cpu multi down and have gotten the BCLK to 220 with no problem. So now , i have tried several different voltage combos to use a 173 BLCK. Even, went upto 1.4vcore and 1.35 qpi and upon doing that, i get the continuous reboot cycle... This really freaked me out. So i hard shut it down, waited a moment, let it reboot and it loaded the secondary BIOS . I have my MEM multi set at 6x to keep that out of the equation. I am pretty new to this, but have a somewhat decent understanding. So basically, how can i get a decent OC with below stock voltages, but cant even reach 3.7 with increasing the voltages by such a large degree. I only intend to reach 4.0ghz to get there for the sake of seeing my own cpu's capability, but not leaving there. I know there is alot of info i have left out, but if we could just start with this and work our way to get some ideas would be greatly appreciated. I have read so much , i just now finally decided its time to post and hopefully find someone with similar components and or problems. Thanks Again! ~dan.

hey shocker, what type of case/cpu fans u use. intake and exhaust what models if u dont mind me asking... ok past the no dvi signal . have it running at the 165 blck with 1.26v ,the manual timings set 7 7 7 20 and what u explained above, set uncore twice the mem multi plus 1. And it doing the double restart again like when i originally built it. powers on off on .

I have 12 yate loons... 5 intake and 7 exhaust.

I do not think that the recommended CAS settings on your memory are 7-7-7-20 as you described. Could you give a link to what DDR3 RAM you have?

What you need to do is to make sure you have loaded optimized defaults in BIOS, first time you manually set the correct settings.

Then you make sure BCLK is 133 and then set memory multiplier to 10 that gives you memory speed of 1333 MHz as the sped you list you are using. Set Uncore twice +1. Now set timings to 8-8-8-24 because I think that is what you have.

I suggest you post your problem in Gigabytes help forum on TweakTown forum. I am sure LSDmeasap or another guy can help you with this.

ok, now i got both pc's back to the 165 blck safely and very cool running. im gonna do as told as we speak. with the 165 blck , it takes my mem speed to 1320 i believe. let me try your suggestions and will repost. again, i cannot thank you enough. not many people would take the time like you gentleman and gigabytes support us poor at best. also , what do u think of a bios update, im currently using f3, and f5 or f6 is available. i think the main change to the newest is updated cpu microcode .

A bios update may be a good idea in this case.

ok, with an 8x mem multi i get 1440mhz on the ram using a 180 blck, this equals to 2880 uncore at 16x or 3060 at 17x, which would be the twice + 1. i think this is the closest i can get to what were looking for. qpi link speed... makes a difference?

Make the QPI link speed the lowest it will go that wont help much but it will help.

The guide adresses that. [:lectrocrew:6]

i posted a couple of days ago to tweaktown. we'll see if they are any help.... but yeah thats the link to the RAM. I guess im gonna try the BIOS update and also try figuring out whats up with the "no dvi-link" after the gigabyte screen flashes very briefly, much much shorter than its supposed to be there.

Please provide a link to that question in tweaktown forum Gigabyte.

u know what, i actually emailed gigabyte tech support, i know its worthless , just wanted to see the response i get. but i have been all around tweaktown. see tons of threads on it.

quite a few more, just search ex-58 ud3r

I APPRECIATE EVERYTHING EVERYONE HAS DONE FOR ME SO FAR.

Did you post a question on the tweaktown Gigabyte forum asking for help on your own problem?

i suggest you do.

[dbee]

ok will do poul. any other suggestions for the time being my friend?

 

[dbee]

hey poul, what do u think about clearing the CMOS before flashing. some forums say it should be, some say it dont need to be done. if i wanted to, i assume ( i know i shouldnt' just assume) remove the cmos battery in the board for a minute or so. What exact purpose does this serve?

 

[dbee]

got the f6 bios, boots to my usual speeds, but still aint working with all the exact settings i've been giving plus some other settings to play around with. Thanks guys.

Looks like everyone is out of ideas. Im just about ready to go to microcenter and start swapping out some parts, see if maybe something is defective. Again, thanks for everything guys. OverShocked and Poul , thank you for your time. If you think of anything else at all please let me know.
