EX58-UD4P and i7 920 question

[jonathankru]

I recently upgraded to i7 and i am stuck with what i am doing wrong.

Below is the highest i tried for last night (still on stock cooling)
memory multiplier = 8
uncore frequency = 16
QPI link speed = 36



All of my specs are in my signature and the voltages are in the SS. Now after running this i decided to go back to 3.4Ghz and increase my ram a little and that is where the fun started.

I changed the memory multiplier to 10, uncore frequency to 20 then tried 21 then tried 22 with no luck and i had QPI link speed to 36 with al of theses settings.
The way i understood it is that the Uncore Frequency must always be at least 2x memory multi.

I even tried 3.2Ghz with higher memory with no luck.
Can anyone point out where i am going wrong?

I will include a bios template later. Thanks for your time.

Re: EX58-UD4P and i7 920 question

I had what i thought was a stable oc so i changed the mem divider and uncore to suit and that is all i changed. below is the semi completed bios template.

Re: EX58-UD4P and i7 920 question

Do you want optimal settings for 3.2 or 3.4?

3.4 may be pretty hot on a stock cooler, but if you want to try that let me know and then I will advise full settings back for you.

For now, looks like you need much more QPI/Vtt, IOH, and ram voltage. Try 1.35-1.4 QPI/Vtt, 1.24 IOH, and 1.66 Vdimm

I will advise full settings for you though, once you tell me for sure what you want to try and run

I think 3.2Ghz will get me buy until i get my water up and running (after i get a conversion kit made for my GTZ). I am just trying to get a feel for how these cpu`s work. And i could t understand what is causing my current limits with my memory. I was shocked that it was so stable at 3,6Ghz with almost no voltage adjustments.

Thanks for the reply. I know you probably get bugged all the time for almost the same thing.

Re: EX58-UD4P and i7 920 question

3.6 with no voltage adjustments? Please do not use Auto voltages when overclocking :)

Here, this should be optimal for 3.36 w/ ram at 1600 for now

BSOD Error codes and what they mean:
0X00000050 << Incorrect Memory Timing/Freq or Uncore Multi
0X00000124 << Incorrect QPI/Vtt Voltage (To Much/Not Enough)
0X00000101 << Not enough Vcore Voltage

Re: EX58-UD4P and i7 920 question

Thanks for all the explanations on the BSOD error meanings. That will make life a whole lot easier. Mine was freezing on the Win 7 Loading screen.Always just before the little animation starts
I only left the advanced ram options and the ram REF`s to AUTO the rest i set manually to the above values.
I will try your suggested setting tonight and reply with results.
Below is the info i know of but i will have to get the rest later.

Re: EX58-UD4P and i7 920 question

When it freezes before windows this is normally not enough Vcore, but can also be too little QPI/Vtt or IOH

Sorry about leaving the spec section in the above post, you are fine already, I know enough about your hardware I mean. Didn't mean to leave that in when I posted.

Good luck with the tweaking and testing, let us know how you get along

No worries and Thanks. I kept most of my specs down so that i knew my batch number without having to remove the heat-sink.

I think i also tried bumping my IOH up to 1.14V. I will start from scratch with your mentioned settings. Also i am using RAID, would that also need more voltage on one of the options in the bios?

[jonathankru]

Re: EX58-UD4P and i7 920 question

Thanks for the settings



I forgot to change multiplier.
One thing i did notice was the tWTP was set to 8 or 10 by default. Maybe that had something to do with my trouble.

Thanks for all the explanations on the sub ram timings. I would have never been able to work those settings out and the way you laded it out made it very easy.

Thanks. Will be re-posting once i have my water cooling working.

Here is a render of what i am going to try make tomorrow

[jonathankru]

Re: EX58-UD4P and i7 920 question

Well i got my water cooling in



My only problem now is that when i tried to get 4.0Ghz to start i get a message about TPM on start up. Just after the bios splash screen starts up. It is fine with 3.2 ; 3.4 ; 3.6 but 4.0 is no joy. Can anyone elaborate on this?
I used the settings that Lsdmeasap mentioned on a different thread(Not Lsdmeasap fault). I can post them if that will make things easier.

Re: EX58-UD4P and i7 920 question

Awesome! Did you fabricate that mounting bracket?

Re: EX58-UD4P and i7 920 question

Awesome! Did you fabricate that mounting bracket?

Thanks .I tried to order it from USA for the last month with not much luck so i designed it and my mate is a tool maker so i asked him to make it so today we made it.

I think my TPM error had something to do with one of the RAM sub-timings.
I am using generic heat paste so i know my temps can be better once i get some more decent heat paste.



Thanks Again Lsdmeasap. Your replys were Very helpfull and made this OC very easy.
I am not going to do much stress testing untill i have decent heat paste and i when i am happy that the mounting of the CPU is good.
Another question. When i have my Qpi set to 36 it will boot fine @ 190/200 BCLK but if i set it to 44 i have no chance of it booting(doesn't even post). Which voltage should i look at and how much would you recommend. Below is current voltage settings.

[jonathankru]

Re: EX58-UD4P and i7 920 question

Just tried to see how much this cpu could do with as little voltage as possible. I know this wont be Prime stable but at least i know 215 BCLK is OK
It doesnt seem to like anything more then 218. But i think that is normal for these boards.

[jonathankru]

Re: EX58-UD4P and i7 920 question

I am happy with 4.2Ghz for 24/7 i just wanted to know is there anything i should change to optimize it more? Thanks for all the help again LSDmeasap. This has gone from the most confusing OC to the easiest OC.
Current settings are bellow.
