Bloat Posted May 1, 2013 Share Posted May 1, 2013 Hi, I have recently purchased a new system including 16GB of Corsair Vengeance RAM (CMZ16GX3M4A1600C9) which I suspect to be faulty. I initially was running the RAM at 1600MHz (9-9-9-24-41) as per the specs and was getting many BSoD and lock ups. I ran Memtest and received 500 or so errors (mainly test 7) and suspected the RAM to be faulty until I read my motherboard manual which advised that 1600MHz was only supported with Ivybridge CPUs (I have a 2600K). I dropped back to the non XMP profile (1333) and Memtest ran one pass ok. The BSoD problem also appeared fixed. A couple of months have passed by and slowly the BSoD have returned with increasing frequency. The first test of Memtest was ok for one pass, so I reinstalled the OS but still received BSoD. I read several forums which suggested trying torture test applications like LinX, OCCT, Prime95 and IntelBurnTest - all of which I receive errors in. (Running at default BIOS settings, no overclock or voltage changes etc) Another forum suggested using HCIMemtest which fails after approx 18-20 mins always reporting problems with the same address. If I now run Memtest I get errors four times out of five often in early tests. I guess this points to faulty RAM? I am based in the UK and purchased from a large Internet based retailer. Is arranging an RMA easy? Thanks Bloat Link to comment Share on other sites More sharing options...
peanutz94 Posted May 2, 2013 Share Posted May 2, 2013 You may need a slight bump in memory voltage. Try setting the DIMM volatge to 1.55v or even 1.6v if need be. Sometimes a Mb will not regulate voltage correctly and the actual voltage at the slot may not be what it should be. Or also some of the larger capacity kits may need more due to strain on the CPU or IMC. If you have the latest BIOS and this doesn't work then test each module one at a time in the first slot with metest86+(that is what Corsair recommends and trusts) for a minimum of three passes or until it error. This would give you a definitive answer pretty quick. Link to comment Share on other sites More sharing options...
xmanrigger Posted May 3, 2013 Share Posted May 3, 2013 Do as peanutz suggested. The voltage maybe the culprit. I would try at minimum 1.5-1.55v. You may get a warning in your BIOS saying that the CPU dont like the higher memory voltage, but you are good at 1.55v. Above, you are on your own. The 2600K is more than capable of running 1600mhz ram. It easily clocked memory to 1866mhz with XMP. And over 1900mhz with manual settings. Hell, an i7-930/950 can run 2000mhz DominatorGT straight out of the box with only XMP. XMP and manual setting both worked on the 2600K in a Maximus Gene. I was using Dominator GT memory though. Not the Vengence. That is not to say the Vengence isnt going to. http://valid.canardpc.com/cache/banner/2110353.png http://valid.canardpc.com/cache/banner/2110333.png http://valid.canardpc.com/cache/banner/2110321.png http://valid.canardpc.com/cache/banner/1790178.png As you can see above, there is no way the 2600K is limiting you unless you got a bad CPU. I am leaning towards the memory being bad. Have you tried it in another system? What mobo are you using? From what you have described, it sounds as though one or more moduals are pooched if it bombs on default settings and you are getting the errors you are with memtest. And no peanutz, I aint following you around. LOL. It just seems we have replied to some of the same threads. Link to comment Share on other sites More sharing options...
Bloat Posted May 6, 2013 Author Share Posted May 6, 2013 Thanks for the replies.. I have tried upping the voltage to 1.575 (setting at 1.58 in the BIOS, showing as 1.575) without success. As this is the highest recommended by Intel for the 2600K (1.5V +-5%) I am not taking it any higher. I have tried relaxing the timings to 11-11-11-30-45 but still get the same errors in memtest. I will take the DIMMS into work tomorrow and test them on a different PC to see if the same results are seen, and also borrow the 16GB of RAM from the test machine to test on my m/board.

Bloat Posted May 7, 2013 Author Share Posted May 7, 2013 Tried on the PC at work (Intel 3770, RAM@1333) and get errors in Memtest on the 2nd pass. Also get errors in IntelBurn Test and HCI Memtest. I'll try the work's PC memory at home tonight but it currently points to bad RAM. Bloat Link to comment Share on other sites More sharing options...
peanutz94 Posted May 7, 2013 Share Posted May 7, 2013 I don't think you really have to do much more troubleshooting. There is one of those sticks that are faulty. Errors on two machines is enough. Please use the link on the left to request an RMA. Keep in mind you will need to send in all the sticks in the kit so you receive a matched set back.
