DangerClose Posted April 1, 2013 Share Posted April 1, 2013 Well for whatever reason my Dominator Platinums I just purchased set my VCCSA voltage to 1.3000 which hosed my Rampage IV Formula and my 3930K. I've done no other overclocking what so ever. Never seen this on an X79 system, this is my second one I've built. I used Vengeance modules before but should have steered clear of these. Just a heads up to anyone, check your voltages...ALL of your voltages first. I spent all day driving today and grabbed a new motherboard and a new processor.....Corsair just cost me $800 today.

peanutz94 Posted April 2, 2013 Share Posted April 2, 2013 Well this is the FIRST case i have ever heard of memory killing a CPU. All voltages set by XMP are indeed safe and meet all JDEC standards.. My guess is you just had a bad CPU or MB to begin with. Even VCcA of 1.3 isn't out of line for your CPU. (max is 1.25v)It may be above Intels max but still acceptable and isn't going to kill a CPU We have seen them run 2400MHZ memory with higher voltages with no ill effects although 2400mhz stable is few and far between. 2400mhz is a pretty huge overclock and mostly unstable for most gaming systems. Can I ask what makes you think the memory killed your CPU and not the MB since you had to replace it too? Link to comment Share on other sites More sharing options...
Yellowbeard Posted April 2, 2013 Share Posted April 2, 2013 Please do 2 things. 1. File an RMA using the link on the left side of this page. We want to look into this for you. 2. Post the complete part number of the modules that you have the issue with. Link to comment Share on other sites More sharing options...
peanutz94 Posted April 2, 2013 Share Posted April 2, 2013 Never seen this on an X79 system, this is my second one I've built. I used Vengeance modules before but should have steered clear of these. Just out of curiosity, what was wrong with the Vengeance modules and were you running them on the same board? Link to comment Share on other sites More sharing options...
Repro54 Posted April 2, 2013 Share Posted April 2, 2013 For the last 7-months I have been running Asus P9X79 PRO, Intel 3930k plus Corsair Dominator GT CMT32GX3M4X1866C9, CPU VCCSA voltage has always been a constant 1.3 with XMP enabled. Link to comment Share on other sites More sharing options...
peanutz94 Posted April 2, 2013 Share Posted April 2, 2013 I'm just asking but why did you need to replace the board too? The only thing memory really could have hurt would have been the memory controller in the CPU. And that shouldn't have taken the board with it too. I really believe your blaming the wrong part. But 1.3v VCCA isn't going to be enough to fry your CPU. Link to comment Share on other sites More sharing options...
DangerClose Posted April 4, 2013 Author Share Posted April 4, 2013 OK so I have been so upset over this happening I haven't been back to post an update: The Part# is CMD16GX3M4A1866C9 Why it's setting the VCCSA to 1.3 is beyond me...the BIOS highlights it in Red and shows it as a warning now, which I caught on my Sabertooth X79 board I had to buy to replace the blown one..... I'm running a Corsair AX1200i which passes self-test, I've been a Corsair user forever but now I am very scared to buy any of their products after this.....

Repro54 Posted April 4, 2013 Share Posted April 4, 2013 I am just a little confused, should the voltage be 1.25v like Peanutz94 stated? Mine has always been 1.3v I know this works well with my setup or should I back off to 1.25v? Link to comment Share on other sites More sharing options...

Mine has always been 1.3v I know this works well with my setup or should I back off to 1.25v? Dude I don't know...that's why I am so scared to run anything Corsair anymore. This literally cost me a new motherboard and CPU from MicroCenter...Corsair cost me $800 in one trip. I am upset and angry all at the same time. I've been a Corsair customer for as long as they've been in business, I've built many systems for friends using their cases, memory, PSUs and SSDs. This seems like such a crazy mistake. Why the dominator plats set the VCCSA so high is beyond me. 1.3 will degrade CPUs over time from what I've read online so be warned.... Link to comment Share on other sites More sharing options...
Repro54 Posted April 4, 2013 Share Posted April 4, 2013 Thanks will check it out. Link to comment Share on other sites More sharing options...
peanutz94 Posted April 4, 2013 Share Posted April 4, 2013 VCCA of 1.3v is not out of line. Your running 1866mhz memory and your CPU only supports 1600mhz memory . The little extra VCCA is where MP is supposed to set it to. .05v isn't going to be enough to fry your CPU. If it was a full .5v i could see it...but not .05v! This seems like such a crazy mistake. Why the dominator plats set the VCCSA so high is beyond me. 1.3 will degrade CPUs over time from what I've read online so be warned.... Thats just it...it's not a crazy mistake! This is where it's supposed to be... It's possible for CPU's to degrade over time...but it will take a lot longer than 8 months...a couple of years at the very least. Please look at my specs which is a HUGE overclock for my CPU and it's been running this way for almost 4 years now and is still just as stable as it was from day one. What were your CPU temps like? Although my system is different and voltage requirements are slightly different the principal is the same. 1.25v is supposed to be the max QPI or memory controller voltage and XMP sets t to 1.35v and i actually need 1.4v to keep it stable. When you overclock this is the chance you take to squeeze out extra performance. I'm not trying to be or sound condescending, but if you didn't want to have to worry about damaging your CPU you should have stuck with 1333mhz or 1600mhz memory to stay within Intels max suggested limits. Running 1866mhz memory in itself is out side of Intel's limits. You bought performance enthusiast memory which isn't like stock memory and will require BIOS settings that may not be within safe limits. But again, this is the chance you take when overclocking. This literally cost me a new motherboard and CPU from MicroCenter...Corsair cost me $800 in one trip. I am upset and angry all at the same time. Why not just RMA the board and CPU? I know your upset, but i really think your blaming the wrong part. 1866mhz is such a small overclock for your CPU it had to be a bad board or CPU to begin with. Why it's setting the VCCSA to 1.3 is beyond me...the BIOS highlights it in Red and shows it as a warning now, And it will go from red to purple too after a certain point. When your overclocking your BIOS will highlight that in red to draw your attention that your about to use a setting that is outside of Intels recommended specs.... But again this is the chance you take when overclocking. I would take Yellowbeard up on his offer to have your parts sent to Corsair for testing. I'm sure you'll find out it wasn't the memory. @ Technobeard peanutz94 - The person you quoted as being the OP wasn't the OP. I've snipped that bit out. I knew that wasn't from the OP, but put that there because of the timeline....sorry I should have made sure that quote was labeled. And If i did mis-label it sorry.

DangerClose Posted April 4, 2013 Author Share Posted April 4, 2013 Thank you Peanutz for your detailed replies, I apologize if I got out of line it's just really upsetting for this to happen. I did RMA the parts and it will be weeks, which is why I bought new parts (Asus Sabertooth X79 and I am running the 1600 MHz memory I had and a new CPU) I guess I just had weak parts that could not handle that voltage. I didn't realize 1866 memory was "out of Intels specs" Is it possible to put the 1866 back in, and just manually lower that 1.3 VCCSA back to stock speeds? I still have the Dominator Platinums here I have not sent them in yet. Link to comment Share on other sites More sharing options...

I still have the Dominator Platinums here I have not sent them in yet. Sure, you could try it. The worst that would happen is that you would need to raise it back up for stability. And , again, i really sorry this happened, but it just doesn't point towards memory being the culprit. Everything towards a bad MB though. There are literally thousands of these kits on the market, and IF the memory were be to blame it would be the very first case I have ever seen. I would at the very least run your memory through memtest one stick at a time to test the memory and see how they test out. There is a link on the left to grab the download if you need it. But let each stick run for a min of three passes. I'm going to take a big leap of faith though and bet they all pass. I hate eating my words and will if I have to , but i'm really betting on them being fine and you just had a bad board. HOWEVER, since Yellowbeard wanted to see them it might be best to send them in just to be sure. Every once in a while when they have claims of really unusual failures they like to test them in house to be sure everything was okay. And this is one of those really weird failure claims. :) I guess I just had weak parts that could not handle that voltage. I didn't realize 1866 memory was "out of Intels specs" Yuppers. The CPU only supports a ma of 1600mhz memory . So if you run faster memory then you are outside the the intended design. Although you have an unlocked CPU that is more or less made to be overclocked,AND a MB that was made to do the same, failures still happen. But without detailed analysis , you may never know. As long as your CPU temps are normal then there should be no real risk to your CPU at 1866mhz. It's all about keeping the CPU cool. Which is another reason I believe you just had a bad board. I would tend to think that if anything were to burn up your CPU temps would have been higher than normal since the memory controller resides in the CPU itself. Of course there are exceptions to every situation, but in general, you would have or should have seen unusual temps. If you want to know the truth 2133mhz memory is about the sweet spot for those CPU's. Some are capable of running 2200 -2400mhz memory depending on the strength of the memory controller. But 1866is just a slight overclock for these CPU's. Good CPU cooling will also help prolong " CPU degradation" that was mentioned. Like i said that could take years to happen. Unless you were into serious overclocking . Ya know guys pushing them to 6ghz with liquid nitrogen,DICE or helium. Or trying to make 1600mhz modules run at 2133mhz or above....those guys can degrade a CPU in minutes! :p: I don't know what part of the world you live in, but i have had ASUS provide me with advanced replacement boards. Had them in just a couple of days. May be an option to explore. Although you may really have to push them to do it sometimes. But they will. As far as I know Intel will do the same once.

Corsair Employees RAM GUY Posted April 5, 2013 Corsair Employees Share Posted April 5, 2013 If you want to submit the memory Danger, please let me know the case number you've setup so I can track it and help you with the process so we can get it back here for analysis.

Corsair Employees RAM GUY Posted April 8, 2013 Corsair Employees Share Posted April 8, 2013 And Repro54 & DangerClose there is no way that a +.05 Volts on VCCSA can damage a MB and CPU. I would suspect there was likely something else wrong with the MB to begin with but as we stated previously we have no problem replacing the memory for you if you like.

Darkwing Posted April 8, 2013 Share Posted April 8, 2013 My processor also only supports 1333 & 1600, but I am running memory at 2133, so guess 1866 should be peanuts..... Link to comment Share on other sites More sharing options...

No, that's me! :p: But yes, your right. It should be an easy OC for that CPU. Link to comment Share on other sites More sharing options...
