GA-790XTA-UD4 and 1090T
« on: December 28, 2010, 05:39:38 pm »
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.
Remember, when all else fails a cup of tea and a good swear will often help! It won't solve the problem but it will make you feel better.

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

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.
