PC12800 ram freezes @ 1600Mhz with rampage II Gene, help please!

[ciro]

Hello,

I have bought 2 packs of F3-12800CL9T-6GBNQ, which are 2G x6 in total. My MB is ASUS rampage II Gene, running a i7 920 SLBEJ d0 stepping. In the MB QVL document, it states that the ram is compatiable in all A B C D types of installation, I assume it means the dual-tri channel on the board should work perfectly.

But when I set the DRAM clock manually to 1600MHZ, keep all others in default, system freezes frequently. Then I tried to load XMP profile1, problem still happens.
Now I upgraded the bios to latest, tried both method, still cannot get it work properly.
So now I am running at 1333

By the way, I wonder if I set the DRAM to 1600Mhz, does it have to be in OC mode. i.e. Power saving mode/ASUS Nap will be disabled?
A bit off topic maybe, my northbridge runs @ around 59-64 degree celsius these days in summer, will this affect the stability of system rather than DRAM clock alone?

Any suggestion or comments are appreciated.

Would try to little lower latencies on 1600Mhz even Corsair 12GB set can't run their 1899Mhz speeds but instead they have to be dropped to 1600Mhz on full x6 controller and to consider speed actually you can with manually set latencies get very very near same results faster on 1333Mhz then on 1600Mhz.

59-64 degrees is insane. I would understand lets say 45-50 degrees although todays boards probably take 70-90 even, but still that's hot as hell.

anyway, perhaps this helps more:

What is your memory voltage? Did you manually enter the memory timings? tCL 9 - tRP 9 - tRCD 9 - tRAS 24

What options do you have in Memory Level Up? Are there any other menus if you set AI Tuner to Manual? This is a configuration issue and I think it is because the UCLK is not high enough to operate the 1600 memory speed.

There are so many settings and options, it would probably be much quicker if you give us a call so we can simply walk through BIOS options.

Actually it would be better if the results were published here in the forums, so that any results positive or negative can provide input for others that might be considering this combo, If it's positive Gskill will get sales, if it's negative other users will know to look elsewhere for teh RAM or a different mobo.

Hiding results doesn't benefit anyone in the long run, (Support Desk Logic 101)

I agree with Tman as well, and that is the benefit of forums, but in these cases we hope the original poster will come back to update the results and possibly become a G.Skill Forum regular. Just without screen shots it's extremely tough to know what's wrong or missing. Also, on the phone it's easier to simply go though each setting, but it simply is much quicker to troubleshoot the issue. Otherwise, the more key settings with values you post, the easier it is to troubleshoot.

Thank you

Sorry for the late response, I just reinstalled my windows vista due to the rubbish SP2 causing problem with windows update. I am a UK user so the support phone isnt really a option for me

Right, I just clicked TAB to check the BIOS info when starting, and it actually shows DDR3-1066Mhz! That is certainly too slow for this ram. But talking about stablitiy, it runs perfectly in current setting.

Heres my current settings in the BIOS

Tuning Mode - Extreme OC
CPU Level UP - AUTO
MEM Level UP - AUTO
CPU Ratio - AUTO
CPU Power Limit- AUTO
AI OC Tuner - Auto
DRAM Frequency - Auto
ULCK Frequency - Auto
All voltages are set to default/auto

-------------------
Failed attempt 1 (Got blue screen during XP installation)
DRAM Frequency set to DDR3-1600, all other settings are kept untouched.
-------------------
Failed attempt 2 (Freezed during vista login when typing password)
AI OC Tuner - X. M. P. Profile 1, 1600Mhz-9-9-9-24-2N-1.50V
all other settings are untouched.

Bios has been upgraded to latest version, rev 0807 or something ,cant quite remember the exact number.

Thanks in advance for any suggestions.

Funny, having same issues with MSI X58 board too....

[ciro]

yea i read ur post as well, how frustrated...
I mean, before I buy all those stuff, I spent days checking ASUS official QVL documents for a perfect combination between cost and performance, and it shows the ram is fine with dual-tri-channel settings @1600 with XMP
Hopefully some change in settings or newer version of bios in future could fix the problem, but for now i can certainly live with it...

[screwtech02]

Yeah, i got the "contact the memory vendor" "your memory isnt on our QVL", funny thing is, these people ONLY test up to 6gb, even if the board states it supports 24, WTF??? You would figure they would at least test stuff with all the dimms populated..... Hope you get your board/mem issues figured out. @ this point im seriously considering reinstalling my 775 setup.....

Try setting BIOS this way.
First Memory Level Up to see if that will AUTO set everything for DDR3-1600. It should basically set everything for you such as BCLK freq, UCLK freq, MEMORY freq, PCIE freq, etc.

EPU II Phase Control - [Full Phase] (Yes, this disables the lower power consumption during idle state)
QPI/DRAM Core Voltage - [1.4V]
IOH Voltage - [1.3V]
DRAM Voltage - [1.65V]

Let me know if this works. This board has a lot of options and you should be able to make it work. I have seen this board go to 1800.

"Failed attempt 2 (Freezed during vista login when typing password)
AI OC Tuner - X. M. P. Profile 1, 1600Mhz-9-9-9-24-2N-1.50V

You might want to try this setting again too just with voltages changed like above.

GSkill tech,
How'd you get roped into working on a Saturday? Glad to see ya though

[GSKILL TECH]

haha donating my time to help people. since you complain about no support available on weekends! =P jk. but yea just making up since we have just been too backed up and busy catching up. this hopefully will buy me some time on Monday to figure out why email servers keep rejecting us. all these random little issues makes it THAT much harder to support people properly.

Might try sending 2 (or more e-mails) instead of just 1). Send a plain vanilla e-mail (no atch), then another w/ an atch, then a third w/ your 2nd atch, etc.

I'm guessing your getting tossed based on an attachment that the servers are seeing as SPAM. Are your attachments in plain text, PDF, JPG or what?

Believe you have my address, drop me one of the ones that are bouncing, I've got a couple e-mail servers I could test them with.

Im back with the test results

After tried the MEM level up and XMP, both failed but significantly better than my results before. The system freezes after running 20-40mins rather than just 5mins

Any further advice is appreciated.

Try increasing QPI/DRAM voltage to 1.5V, a lot of people with this mobo have been needing a little more than 1.4V. What are your multipliers such as your BCLK and UCLK and such set at? If you could post your BIOS settings, that would be easier to see if you are missing anything. Also, have you tried the other 3 slots?
