Hey guys, for several days I've ridden my new 1090T BE, in a GA-790XTA-UD4, but I'm having several stability issues with the OC. I tried everything in the bios, and no way to stop 100% stable, so this happening to me is the Bios, I have installed the latest (F4a BETA), and I wonder whether to take any new bios "official" than beta.
A greeting and thanks.
Sorry for my bad english...
-
Hi there,
I had a good O/C on this board with the 1090T using the F4a BIOS so I would be surprised if it is the BIOS causing the problem.
You can go back to the F3 BIOS just to see if that improves things. Use QFlash to update the BIOS not the @BIOS utility.
If you are still having problems please post back with your full system specs, as instability is more likely to be due to some other component.

Hi, I've tried the F3 BIOS, but when installing, I have a problem, and all cores will speed that I set up (4GHz), but the No. 1 core is at 800MHz ...
-
Have you disabled the Turbo Core Boost feature in BIOS? You need to do this if you are trying to O/C.
Also it is a good idea to disable the CoolNQuiet feature.

Hello, already solved the problem ... was a defective RAM module ... I've changed and is running smoothly.

Yes, I have turned off any power saving or similar.
But now I have another problem ...
The fact is that I have it 100% stable at 4GHz @ 1,44v, I'm trying to get the 4.2 or 4.3 Ghz stable, but I can not pass of 1.50 v, because the PC is restarted immediately.
I tested to 4.2 GHz, with a vcore of 1.48 v, run the Linx goes smoothly and about 2 or 3 passes, until it jumps error, as unstable, okay.
Reboot and I put the vcore 1.50 v, and when I enter Windows, run the Linx and just put the computer restarts.
As it may take the Linx to 4.2 GHz to 1.48 v the vcore, and not go to 1.50 v?
Temperature problems are not because I have a good cooling liquid. Has never reached 34 º C.

If you are running your RAM at 1600MHz try pulling it back to 1333MHz as this may help.
Also try adjusting the NB frequency and voltage a little as this is what I had to do to get 4.2GHz on the 1090T.
-
Ok, thanks, the NB is at 3000MHz, and the voltage of the CPU / NB to 1.40 v.
Think the rams are `1333MHz 4.2 GHz can get more easily?
-
You should try bringing your NB Frequency down from the 3000 Mhz, I think I had mine at around 2300MHz.
Bringing the RAM down to 1333MHz will offer better stability as the AM3 CPU's really don't like RAM running above that speed.
-
Thanks.
At the moment I put the rams at 1333MHz @ 7-8-7-20-30-1T.
Have passed the Memtest 4.0 without problems.
I've been reading various guides, like this:
http://www.overclock.net/amd-cpus/884103-1055t-overclocking-guide.html (http://www.overclock.net/amd-cpus/884103-1055t-overclocking-guide.html)
It is true that reports to recommend to 1333Mhz, still do not understand why, but I have done so.
I left the 3000MHz NB to 1.37 v.
And I'm running a Prime95 @ 1.47 GHz to 4.2 v, to see what it holds.
V 1.47 is a very high voltage for 24 / 7?
-
1.47V shouldn't cause you a problem as you have good cooling on your CPU.
I have seen cases where people have had the voltage up to 1.55V when O/C'ing.
The reason you should run your RAM at 1333MHz is due to the design of the AM3 CPU's and I have tried to explain it in this article: http://forum.giga-byte.co.uk/index.php/topic,2515.0.html
-
I read that the Thumba have recommended voltage limit lower than the x4, so they say, going from 1.47v and is entering a risk area, right?
And thanks for the clarification of reports to 1333mhz, I just read, and I was surprised to read that you can break the memory controller, for use at 1600MHz ..
And I was trying to upload to 2000MHz ...
Thank you very much for your help
-
According to AMD the official top limit for the 1090T is 1.475V. When you go higher you do run certain risks but a lot of the issues are due to the increased heat that higher voltages produce.
Although it is on a different Motherboard, here is another item I wrote regarding overclocking with the 1090T which you might find helpful. http://forum.giga-byte.co.uk/index.php/topic,3637.0.html
-
Thanks.
I'm trying to quit stable at 4.2 GHz, but it is telling enough.
Right now I have the NB @ 3000MHz @ 1.40 v, you think you would have to lower the frequency and voltage? Much voltage 1.40v for IMC, to use 24/7?
How fast would you recommend leaving the NB without losing "power" of these 4.2 GHz?
-
Try pulling your NB Frequency back to about 2600MHz or slightly lower.
Leave the voltage alone for the moment. If you can get stable 4.2GHz O/C with a slower NB Frequency then you can start trying to pull the voltage back.

Hey nice clean looking system 8) Very tidy. You should put it on our Pictures of Members Computers here:
http://forum.giga-byte.co.uk/index.php/topic,2373.0.html
-
Thanks.
Well I will try to see if it's 4.2 Ghz with current Vcore.
Download the NB to 2600mhz as you say, to see what happens.
@ Dark Mantis: Now hang a picture, I've seen to loop, and it is amazing! If you live somewhere it gets cold, temperatures have to be amazing! ... xD
-
They can be but I tend to use the external radiator in the summer months more as during the colder months it can get too cold and cause condensation problems inside because of the difference in temperture of the cooling liquid to the indoor ambient.
-
WOW, then you live must be quite cold .. xD.
Here on the island (Tenerife) in the month of December and we are at 17 º c, and almost no rain ..
Returning to the issue of the OC, I have the CPU already more or less stable at 4.2 Ghz and 2800 in NB.
But I have a problem ... and not get to spend the linx to 1.50 v.
A 4.3 GHz and 1.48 V to lynx, but fails by instability.
Then I put 1.50 v 1.55 v and not even pass me the linx, just run it, restart the PC alone.
That that happens? have any limitation of voltage?
Is the 1 st time I ride a PC with an AMD CPU and I'm kind of lost the truth.
-
Hi,
yes, if BIOS notices a problem with overclock settings then it can restart the PC and reset to safe settings. This is to help protect the motherboard and other components.
I have to say that I couldn't get past 4.2 GHz very easily with my own system and as I am not into overclocking I didn't spend too much time trying to go any faster.
-
Wow, that bad ... :-\
And there is no way to remove this security system?
-
it's not a security system as such, it just recognises that the settings made are likely to cause damage to the motherboard, CPU or some other component and as it is part of the BIOS I don't think it can be turned off.
This is where the challenge of overclocking really kicks in and it is only through experimenting that you will find the limits of your own system. As I said before, I struggled to get above 4.2GHz and gave up at that point because I was only doing it to find out how far I could easily go and so that I could offer advice to others if needed.
I finally settled on 3.8GHz but lowered the CPU voltage down to 1.325V which gives me lower temps but a reasonable speed increase and system stability.
-
Okay, I understand, well then I will have no choice but to try to get as often as possible below 1.50v.
This issue could be solved with a new BIOS?
I've seen people who feel the same even with the 890FX UD7, and the truth which is a shame, buying a Black Edition CPU, and not being able to get the most performance, a limitation of voltage.
Known whether this board will be taken to new bios? or 790X/GX/FX and lay them aside for the new 890?
-
Not sure about future BIOS updates but you might like to ask Gigabyte Technical support about this and the problems with increasing the voltage above 1.5V.
You can contact them here: http://ggts.gigabyte.com/tech.asp?ClassID=2&Country=Spain&SourceWeb=B2C It could take a while before they reply.
-
Thanks, I'll ask to see what I say.
-
One question, that actually serves the CPU VDDA? Comes by default to 2.50 V, this voltage I touch it?
As the NB voltage, so I have a 1.12, which is the default, I have to give more power?
Thanks.
-

Yes, you can increase this voltage a little for better CPU/NB stability if needed. I didn't need to adjust this setting though so be careful when you do increase it not to make too big a jump.
As the NB voltage, so I have a 1.12, which is the default, I have to give more power?
You might find that a small increase to the voltage will help. I had to use 1.150V on my O/C for stability
-
Thanks.
It is normal for this motherboard come on CPU PLL to 2.50 v? and the minimum is 2.20 v? it is way too? I remember my old Q9650 with 1.60 v enough for a good OC, I guess that AMD platforms will be different, right?
-

Yes this is normal and the maximum is about 3.1V if I remember correctly.
I guess that AMD platforms will be different, right?
In a word, yes. AMD & Intel handle things very differently.
-
Thanks.
I ask my last question on the AMD platform.
I've seen the voltage SB / PCI / PLL, so called, and comes by default 1.80V.
I recall that the 775 platform to put this voltage is 1.50v, so, as I put it here.
For this platform, it is natural to use v 1.80 for PCI?
What is the recommended voltage for use 24 / 7?
-
What is the recommended voltage for use 24 / 7?
If you load optimised defaults in BIOS and then re-boot your PC all voltages will be returned to their default states. These default voltages are safe and recommended for use 24/7.
Before you begin over clocking it is a good idea to take a picture of these settings in BIOS or make a note of them in the User's Manual (which is what I do) so that you can have them readily at hand to reference when tweaking.
NB/PCIe/PLL Voltage Control is set to 1.8V by default and this is normal.
-
Thanks.
Well, unable to move from 1.50 V, I left it steady at 4.2 GHz, 3000MHz NB and 1600MHz RAMS.

Voltages:
CPU: 1,48v-1,50v load
NB:1,16v
CPU/NB:1.37v
HT:1,26v
RAM:1,65v
SB/PCIe/PLL:1,82v
VDDA: Stock (2.50v)
Temps: Idle:18 +/- Load 31/33 +/-
-How to see the voltages?. Are fine for everyday use?

Hi
Nice 1GHz O/C you have achieved.
The voltages for the Motherboard are all OK and although the Voltage for the CPU is at the top end, I don't think you will have too many issues running 24/7 as your temperatures are really good.
Overclocking, by its very nature, can shorten the life expectancy of the components and this is always something you need to bear in mind. The faster and harder you push your PC the shorter life span it may have and it is always a compromise between the two. As I mentioned before I decided to pull my own system back to a modest 3.8GHz on the CPU, the RAM running at 1333MHz because of the known issues with running RAM at a higher speed on AM3 CPU's, with all other settings left at default. This is a compromise between extra speed or PC longevity and I decided I would like my parts to last as long as possible.
-
I know you do OC shortens the lifespan of the components, but I get the best possible performance, without me through voltages.
When we talk about it shortens the life, the processor is not going to last a year or two, will take her years, but less than if this stock. right?
-
Yes it shouldn't make a drastic reduction in the lifespan expected but it obviously depends on the amount of stress that you put the components under through the overclock. Voltage and heat are the real killers.
-
Mainly use the PC to play from time to time, and spend some bech, but little else. So it is not that much time under great stress.
By the way, today I downloaded the Easy Tune 6, and I have a problem.
Why are not the voltages?

Hi,
you might find AMD Overdrive better for checking temperatures and voltages, especially when overclocking as a lot of software, such as EasyTune6 struggle with this.
You can download AMD Overdrive from here: http://game.amd.com/es-es/drivers_overdrive.aspx
-
Thanks, ;)
-
I'd be careful with using AOD to check voltages or overclock values. I've had it displaying false info on 2 PCs in a row so far. CPUID HW Monitor is my tool of choice if I a want to take a quick peek. It's simple, somewhat crude but fast and shows a lot of info. Take note that it's not very detailed in terms of voltage readings.
Still, that's better than AOD telling me that my RAM, rated at 1.65v, is running 1.60v heavily overclocked. Especially when it's at 1.72v in reality.
