Intel DX58SO2 and Corsair CMD12GX3M6A1600C8

[Mia!]

I built a system based on Intel motherboard and a kit DX58SO2 6GB (TR3X6G1600C8D). I had some success running the XMP profile, on the other hand, infrequently restarts with experience with a nice flashing red light on the motherboard. When I entered the BIOS memory is set to 1067 MHz (This RAM is 1333MHz SPD). I also had problems with the suspension system when resuming any form of sleep / hibernation when using XMP, but every time I use a frequency of 1333 MHz dream resumes work well.

I have been in 1333 9-9-9-24 1.5V and did so in 8 hours before the negotiations started Prime95 meant for rounding mistake. Then I tried 8-8-8-24 1.55V 1333 and did 14 hours with 0 errors in Prime95.My only anxiety is that I spent time before Prime95 only for the system to become unbalanced and crazy anyway, and I be anxious that to carry on.

If 1600MHz is overclocked to a full channel is 1333MHz overclocked for 2 channels? I search for 1067 MHz for actual steadiness and durability of hardware?

This makes me laugh Intel tech support at all times. XMP is its technology. It is their technology that sets the voltage to 1.65v RAM. So no, it will not hurt your CPU. I can tell you first hand that I've been running 1.65 v for almost two years without any mishaps.

It would be his period 1600MHz overclock. Whether one or two channels. One or two channels is a function of the MB, not the RAM. And 1333 would be of maximum frequency values of one or two.

[Himalayan]

Yes, you may need to add stress to the memory controller. That should be labeled QPI / VTT or something similar in your BIOS. It should be set to a value of 1.35V to 1.45v.If the voltage increasing memory controller does not work you might have to turn the frequency up to 1333MHz and observe if it is steady.

There is always the possibility that the memory controller on the CPU just does not handle the overclock. Of all the R-7 of the 950 has the worst driver in the memory and do not always handle the overclock very well.

I have increased the tension Uncore (QPI) XMP settings of 1.2v, beyond the "default" setting 1.2250, all the way up to 1.25v. I thought I be supposed to establish small and test. As I write this response, I'm running at 1600MHz 6 RAM once more and run the stress test of memory on the Intel Extreme Tuning to observe if it would blue screen on me. He also ran a few minutes of Prime95. Obviously, not enough to know a lot but enough to pass the "drop in the first 2 minutes' test. I wonder why the XMP setting would reduce the voltage below the default anyway I'm still here and seem stable so far.

[Ramona19]

I would add a bit more QPI voltage. Be a man of about 1.35v-1.45v.Just not going over 1.45v I can say is Intel specifications. That should pave the rest of their troubles there.

On the XMP settings not being correct. I'm not sure. Some MB do well, others miss it. So it's just a good idea to check and adjust if necessary.

So I found myself quite free of events with 1.25v Uncore / QPI for a week. I came home today and clicking a mouse button to wake up my PC and did not resume successfully. However, it was a little different to how it used to not too awake when I ran the ram at 1600MHz with a Uncore 1.2. By this I mean that the zip code that appears on the LED boards that read "30", which is consistent with a successful resume, while before it shows a different zip code (can not remember burst) . However, the video does not seem to want to wake up.

Oh I should also mention the issue noted in my last message. The problem with the video driver and said: "Display driver stopped responding and has recovered" appears to have been solved by adjusting the power management related to the PCI express "Link management of state power".

This only reaffirms that it was the memory voltage controller. It may take a modest more to acquire the other entire bug worked. If 1.3V does work, that's immense! In general, the lower voltage to maintain stability is the finest. If doe not remain steady or continue to have the trouble of sleep / wake just add a bit further QPI.

[jamiejohn]

Do not make me extremely long at 1.3V. In a few hours later I had an accident with a red light flashing red light. I was in the middle of installing a beta driver commencing Nvidia with "clean" installation technique and had retired only all my video drivers. I was not paying much attention, nevertheless it was just when the installer can reboot the system or the system may have crashed. Usually precedes a red light accident.

[Man!nox]

So it seems that 1.25v is more stable than 1.3V. After removing tensions in that range from stable, I will try, in conclusion 1.35vy perceive how it goes. I will stay you up to date.

If stored in the DIMMs, there are more than a few profiles stored XMP a variety of boards? The documents mention that the values are the consequence of collaboration flanked by Intel and many memory manufacturers. In the end, who really is responsible for determining the settings?

[sushantbankar]

XMP is just another SPD setting. It is stored in the memory card. Only one or two XMP profiles on a stick in all-purpose.

[LavinaD]

As an update to the discussion QPI voltage, 1.35v I have been running for more than a few days and all is well so far. I'll keep a gaze on it and then back if anything happens.

I would establish the stress test once more, nevertheless I've found that my system has been a long time and sessions of Prime95 Memtest with no errors, only to crash, while the simple use of windows in normal conditions. I had the impression that "stable government" was more difficult to achieve than "sitting around doing nothing stable," but recent events that occurred a few seem to prove otherwise.
