Problem with New AMD 990fx build

[TonyM286]

That page does not match my manual or the actual etchings of the numbers on the motherboard RAM slots

My slots on the motherboard reading them from left to right with the cpu at the top and the power connector on the right are labeled 4,2,3,1. My manual chart says 1 and 2 or 3 and 4 for Dual Channel mode.

As shown here in revision 1001 of the manual.



And the table here:



I don't know what revision of the manual you are using, but mine matches the etching numbers on the motherboard. Hopefully we are on the same page now. RAM slots 1 and 3 are not working at all now, RAM slots 2 and 4 are fully functional.

Question is what to RMA the motherboard or the CPU. I was hoping you would have some insight on this question.

Thank you,

Tony

Tony, this is directly from the manual from your board. This is Dual Cannel config....

[TonyM286]

No problem.

Any idea why the Ripjaws work fine in single channel only on Memory Channel 0, slots 2 and 4, but will not work at all on Memory Channel 1, slots 1 and 3 in single channel? Sounds like the RAM is fine and either the motherboard or CPU is the issue?

I was even able to run hours of Memtest 86+ with the ram in single channel on slots 2 and 4 at 1600 with tighter timings of 8-9-8-28. No problems.

One Channel of this board or CPU is not working. I hate guessing what to RMA first. I think I am going to try the CPU first, and I am sure that is what Gigabyte will say...lol. AMD will tell me the motherboard, G.skill will blame everyone else...Although I don't think it is the ram it runs fine on channel 0.

I am sorry we had some confusion, it happens. I appreciate your persistence, even though you thought I was a dunce...lol.

I will post the solution of this issue here as requested.

Thanks again,

Tony

My bad, I was at work but thats the config.... The slots are black on the 990FX not blue and white like the 890FX... OK hope this helps... The dimms are relabeled, you are correct....... I feel dumb.... Stop it DMDuff(pure OC member). I just reviewed that board too... LOL, for some reason at work I thought the dimms were white and blue.....

I didn't see your memory on the approved list but that does not mean it is not compatable. I would call Gigabyte on Monday and talk to a service rep. Here is a link to the Qualified Vendors list. If I remember, guys were having problems with RipJaws on AMD platforms in the past. A Gigabyte Tech may be able to help more. Again, sorry for not knowing Gigabyte relabeled the dimm slots Tony!

I do it often ask the guys here..... I am not saying it is a compatability issue. It may not be but there was a RipJaw problem in the past. That I do know. Almost all DDR3 Memory is compatable nowadays...... I see your problem is not common as RipJaws are very popular.

Lets work on this.... Can you take pictures of your Bios??? The main advanced page and the memory page. Maybe it is a setting. If you put those puppies in Dual Channel config, they should work...

[TonyM286]

Since you are helping, thought you would want to see the rig in its current state.



Love these new black colored Gigabyte boards, just hope I can get it up and running.

As you can see a totally black and red scheme with the Antec blue LED fans.

Thanks again!

If I try to put RAM in configured for dual channel I can access the BIOS but it locks up when I try to move the arrow key. The machine states it tried to boot, but failed due to an overclocked situation.

RAM slots 1 and 3 are now also freezing up individually in single channel mode...the problem is getting worse. I was able to at least run the machine with one stick in either 1 or 3, but was never able to 2 sticks in 1 and 3.

Only 2 and 4 work as seen in my picture of the rig in my above post. The RAM seems really good and I am able to get good timings with both 2 and 4 populated. BIOS is accessible and it can run Memtest86+ overnight configured like this. The motherboard detects them fine at 1600 speed but the timings it tries to use are tighter than the RAM spec of 9-10-9-28...Auto detect tries to run them at 8-8-8-27, which I did not allow.

RAM is set to 1.5v, CPU is set at stock voltage. I did try one stop of overvolting of the RAM and CPU no luck on getting slots 1 and 3 working.

Thanks again,

I pulled that off the Gigabyte website. That was the 890FXA manual..... I was in a hurry when I arrived home to help you..... I updated my screenie to the 990FXA after i noticed it..

That is odd. It leaves me to believe that is is a compatability issue more than anything........ In your photo, you are in single channel. After all the conversation, I am sure you know this. I want to make one statement. Dual channel oppsed to single channel offers less than 1/2% performance gain. In most applications there is no performance gain. I would run it till monday with it in single channel and call Gigabyte. It locking in the bios is very unordinary. Put it in single channel and take photod of the advanced screen and the memory(dram) screen..... maybe, just maybe... a adjustment in the bios and then switching the modules to dual channel position may do the trick...... BTW, you did a cmos reset Tony? If not, try that......

[TonyM286]

Hello,

Hope you are well.

Went from the F3 BIOS to the new F4 BIOS and the problem appears to be resolved. Running dual channel now in slots 1 and 2 and has passed one pass of Memtest86+ so far. Will leave it running for a few more passes to see if it is stable.

Thanks for the help!

Glad to see you got it on the right track I hope it pans out for you. Keep us updated.

The board is so new, I didn't phantom the idea of a new bios was even available. That's good stuff Tony. Very good at your persistence...... Stick around at Pure Overclock. Although we do not always have the answers, we all try to help one another......

[TonyM286]

Yup Gigabyte is working on F5 BIOS already. Others are complaining of not having LLC control in the BIOS, and are experiencing Vdroop because of it. Gigabyte says the Vdroop is needed for the upcoming Bulldozer CPUs.

Tony, I did not have LLC as an option in the review and I did comment on that. I did not suffer any Vdroop. In a matter of fact, it was running over the set voltage when I pumped 1.6V or higher on my dry ice run...... Bios update.. Good find... Hows the board treating you?

[TonyM286]

Howdy,

Hope you are doing well.

Temperatures being reported by AMD Overdrive under 6 core full load at stock 3.2Ghz seem real high, 62 degrees Celsius. Core Temp version 0.99.8 Reports core temps are at 50 degrees Celsius with the cpu also at 50 Celsius. Gigabyte Easy Tune 6 is showing the CPU at 54 degrees Celsius. All of these seem pretty warm with an ambient temperature of 25 degrees Celsius.

For full load on all 6 cores I have Seti@home running.

These temperatures only go up 2 degrees if I overclock to 3.6Ghz with stock voltage, as high as I will go on the stock cooler. However, the AMD Overdrive core temperatures are scaring me they are over the supposed limit of 60 degrees Celsius AMD says not to go over. Although the motherboard is set to give me a warning at 60 degrees Celsius, which it has not done. Therefore I believe the high temps being reported by AMD overdrive are bogus.

What program do you use to monitor CPU temperatures, that you feel reasonably comfortable with?

Thanks,

Tony

Use coretemp and I would not run temps that high. What cooling are you using?

[TonyM286]

... Hows the board treating you?

I love the features of this motherboard.

I really pulled my hair out of whether to get a 990fx motherboard or go Intel with a Z68.

Ultimately the 990fx just has way more going for it. This board has 8 6 Gb/s SATA ports, Z68 4 6Gb/s and 4 3 Gb/s, can't see being gimped on the SATA ports. Board has 2 full speed 16x PCI-E or even 3 at 8/8/8, 2 1394 ports, 4x PCI-E, useable PCI slot, 4 usb 3.0 counting the internal header, optical audio out, HD Audio, 6 Gb/s eSATA, and it can take Bulldozer CPUs.

Z68 feature set just did not wow me, even with their SRT cache tech. It just can't compete with the 990FX chipset boards. If Bulldozer is as good as the motherboard, I will be extremely happy, if it is a little slower than Sandy Bridge I will still be happy because the motherboard has all the features I need on it.

Wife already knows I want the 8 core Bulldozer for Christmas!

This new system is an upgrade from an old Opteron 170 workhorse, which is still running, except the capacitors on the motherboard are beginning to bulge on top, hence the need to move on.

I still wish that Opterons were compatible with the current consumer AMD socket motherboards, the memory controllers on them are grade A. That old 170 still handles modern software very well.

Coretemp reports all cores at 50 degrees Celsius.

AMD Overdrive reports all cores at 62 degrees Celsius.

Full load on all 6 cores. Stock voltage, stock frequency 3.2Ghz.

Craptastic AMD stock cooler with factory installed undersized fan at full RPM

Cool and Quiet disabled

Smart fan disabled.

Antec 900 case fans set to high speed, 2 in front pulling air in, one in back blowing air out, one big 200mm on top on high blowing air out.

Ambient temperature at 30 degrees Celsius.

Thanks again,
