Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

so it was dram termination too low? i keep forgetting your using a 6core and not a 920/4 core cpu,those chips can run lower qpi/vtt compared to the four core cpu's,the uncore freq can be lower than 2x ram multi aswell,this will help

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

Well...I can not say yes yet directly, but definately it changed a lot, now i can go for lower QPI/VTT and higher uncore frequency.
And yes, i perfectly know that 970 6 core CPU can go lower than DRAM / 2, but don't forget taht the goal of my OC is:

The Goal of my OC is to have completely stable 24/7 system with one of those:
1. BCLK 143 mHz, uncore at least x24 preferably x25-x27, x14 memory multiplier = 2002 mHz memory.
2. BCLK 138 mHz, uncore at least x25 preferably x26-x27, x14 memory multiplier = 1932 mHz memory.

Yet - i can run stable 2, but with 1 (143 BCLK) i need more extreme QPI/VTT to run at least x26 uncore.

Now i use 140 mHz BCLK, x26 uncore, 1.455 V QPI/VTT, 1,38125 V CPU Vcore, 1.180 V IOH core.

So far - pretty stable, will have to see how it will be after stress tests...

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

I found that on higher than 136 BCLK when i set DRAM to 1.66 V (mb bios sensor, and all possible voltage measuring software all shows actual 1.61 V) - it's seem to be not enough (according to perfomance at least, especially it's noticeable in video games).
But when i set next notch (sadly my motherboard's next is already 1.68 V, huge leap already for such sensitive hardware as memory.. (actual reported as 1.645 V which ~ = to my dram spec of 1.65 V), so when i set it, everything seems to be allright, but after few hours under heavy load i can get 0x124, my guess - is that it's operating normally as it should, but in some cases it overvolts a tiny bit - and this leads to crash.

Question is - considering what i have said above, if i will raise DRAM termination's and vrefs voltages 1-2 nothces more than DRAM / 2 value, won't it improve stability of memory?

P.S. Oh, and also i found that if you use 143 BLCK on my system (= 2002 mHz memory) - it's utterly impossible to detect whole 12 Gb without setting 1.68 V DRAM on my system...
Going beyond 2002 mHz seem to be impossible at all. I was trying to add QPI/VTT 1.515 V and higher vcore, without luck. Always sees either 4Gb either 8Gb, but not 12.
So my maximum reasonable DRAM frequency is 2002 mHz.

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

So still, anyone got a clue of why when i play GTA IV with overlcoked memory - i got noticeable effect of, which i can describe as: "ingame objects appear too close / right in your face"...?
In theory if you up voltage somewhere - then somewhere it can go down...But where should i look? What should i try?

Please help me to solve this guys!

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

I'm a little late in the game and have not read the whole thread. But...

So my maximum reasonable DRAM frequency is 2002 mHz.

This is the case for I'd say 90% of the x58 population and it's up to your CPU if it'll let you play any higher...

Can you provide a screenshot of this issue? if you are using MSI Afterburner to Overclock your GPU, in the settings you can configure a key to take screenshots for you and it will put them in a folder you specify...

It's never too late ;)

No, my videocard is factory overclocked, i don't use anything additional like Afterburner, you can see my full PC specs in profile.

It looks like this (video was shoted some time ago when i was pushing my system to the maximum, now it's a bit better, but still):
GTA IV - YouTube
Check 00:16 - 00:17 moment, it's very illustrative, object have appeared right in my face :(
And this is much more noticeable when you're actually playing, then on video, of coure...

I was thinking of 3 main possible cause:
1) After overclock something goes off with videocard (undervoltage, but where?), probably PCI-E lanes? If i'm correct, data is transfered from RAM to video card through northbridge and then goes to PCI-E?
2) Hard drive maybe? I got pretty powerfull SATA II, 10000rpm WD for the system, it outperforms all of my other harddrives easily...But since i got 4 hard drives, and 2 usb devices (midi controllers for music, which is powering from USB), this why i thought maybe i need extra voltage on southbridge? I've added a bit to ICH Core, now it's 1.14 V, haven't helped too much.
3) I'm just thinking of maybe i need to raise DRAM termination's and vrefs voltages 1-2 nothces more than DRAM / 2 value, won't it improve stability of memory? Maybe it's just a bit undervoltage in there?

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

I see that as more of a software bug over hardware.

ya the shed appeared but then you couldn't blow up the car with a rocket when the car was there.

that game is DX9, I'd try an older driver to see if it still does it. you can get 266.77 from gigabit's site under drivers for your card; GIGABYTE - Graphics Card - NVIDIA - PCI Express Solution - GeForce 500 Series - GV-N580UD-15I (rev. 1.0)

I'd try that before playing with any hardware adjustments.

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

ya the shed appeared but then you couldn't blow up the car with a rocket when the car was there.

Now that's typical GTA IV bug, it's not a problem, but when objects appears - it's not typical at all, believe me, i have played it not on single system :)
And yeah, that was what i thinking first - driver, i was trying every driver from oldest my card can eat, to newest (include beta), i have tryed completly fresh install, nex direct x etc etc.
Oh yeah, i have even changed 3 completely different GTX580 cards, thought it was card itself - but no. So it's kinda related to something else.

I think it's related somehow to os, coz sometimes it is much better, sometimes it is like on video, but i don't understand what exactly make it better..I could see a little bit of improvements when upping PCI-E voltage 1-2 notch, but it's not complete...

So, speaking of direct question, what exactly feeds videocard data stream in bios?

[Vinster]

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

ok, i would had pinned it to a driver or Physx issue, if you have already tried rebuilding the OS and also different drivers from new to old... I'm not sure what else to try.

and I'm sure you already applied all the patches for the game and are also possibly running it in compatibility mode?

what other games to you have this issue with or is it just this game?

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

Every game, except those who doesn't have dynamic LevelOfDetail system at all (like Hard reset for example, it loads whole level at once, everything).
Yes, of course i've tried patches and different graphical settings, it's not the cause.

What i think - not enough voltage somewhere, and i got reason for this, sometime when i had set PCI-E voltage few notches up - it have become a LOT better, but i was just afraid to go on, because i don't understand how exactly feeding of data to videocard goes, or what videocard related voltages exactly do, that's why i'm here.

P.S. I got pretty weird problem, now i'm on default 133 mHz BLCK, CPU Vcore 1.35 V, QPI/VTT 1.395 V (also tried 1.415 V), x14 memory = just 1862 mHz, default timings manually, uncore set to x24 = 3192.
OCCT low data rate / Linpack -12 hours no BSOD, BUT...When i use OCCT large data rate i got errors in 5 minutes O_O
What to try? What exactly this error could mean? (except some kind of low-level instability, i mean what exactly could it mean in terms of my BIOS settings)
My settings now is so basic, almost deafult...Something is off clearly.

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

Have you verified that the CPU is properly seated and that all the pins in the CPU socket are intact? and have you re-run Memtestx86 to confirm that your memory isn't causing any issues in the high end of the memory map?

OCCT errors during Large Data Rates leads me to look at that.

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

Double checked. everything is fine here, same with memory, seats perfectly.

and have you re-run Memtestx86 to confirm that your memory isn't causing any issues in the high end of the memory map?

Few days ago i've done memtest - everything was fine.

P.S. Why ET6 still shows that dram termination and vrefs are 0.75 V, but they're actually not?
Maybe my system still forces somehow 0.75 V even after i apply 0.83 V through bios?
Or is it just another stupid bug from ET6 utility? :D

[Vinster]

Re: GA-X58A-UD7 rev 2 memory / uncore OC stability trouble.

I never used ET6, it was way too buggy for me on my AMD 790, 890 and also x58 boards, I just stayed away from it.

I always used other tools, but for voltage monitoring, if it wasn't in HWMonitor, I didn't need it in windows personally.

In my case: this is utterly minimum BIOS voltages for default setting and memory x14, that can pass OCCT with large data rate 12 hours without error:

Extremely hard QPI/VTT for default x21 uncore...
I'm kind of disappointed.

I also tested that same CPU Vcore is enough for BCLK 143mHz, to pass 12 hours (with x12 mem multiplier, to exclude memory)
But when i try same default settings for 133mHz BCLK that are listed above, with the only difference that i set uncore (just!!!) to x22 - i got OCCT large data rate error with QPI/VTT 1.395V, with 1.415 V and even with next notch up also...

Maybe when uncore is set to higher than x21 i also need to add vcore?
I would still like to go at least for x24-x26 stable uncore.

Please, any advices?
