albedan Posted January 27, 2013 Share Posted January 27, 2013 Hi guys, I've been putting together this system: - Corsair CMX8GX3M2A1600C9 (2x 4GB, 1600MHZ, 9-9-9); - Asus P8B75-M LX (Intel B75); - Intel i3-3220T (low power Ivy Bridge i3); Here are the results: - With this configuration, the pc boots, the fans spin for 2 seconds, then reboots and goes into a boot loop (2 sec - reboot - 2 sec - reboot ... endlessly); - Changing the ram with 2x 2GB modules and 2x 4GB modules (from another manufacturer) it works perfectly; - I tried to boot with a single module of Corsair CMX8GX3M2A1600C9, it's the same; - (now the strange thing) the pair of Corsair CMX8GX3M2A1600C9 boot fine in another machine (Asus M5A88-M and Athlon X2-250). I see this pair of Corsairs are not on the QVL of the Asus P8B75-M LX, but they should boot nevertheless... Can you help me? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 28, 2013 Corsair Employees Share Posted January 28, 2013 Please post the version number on the modules, I suspect the issue is the density of the modules. All of our current modules are made with 512M X * memory IC's which would not be compatible with this MB. Link to comment Share on other sites More sharing options...

All of our current modules are made with 512M X * memory IC's which would not be compatible with this MB. I'll let you know when I get home. Anyway, I see that lots of Corsair modules are listed on the QVL, so if all of your current modules have the same density... Link to comment Share on other sites More sharing options...

peanutz94 Posted January 29, 2013 Share Posted January 29, 2013 so if all of your current modules have the same density... Yes, thats correct. Anything being made today or in the last year or so would be made with 512MB IC's Have you ever updated your BIOS? And aree you clearing the MOS before swapping modules? According to the DDR3 IC Inquiry those should be made with 256mb IC's and should work for you. http://forum.corsair.com/forums/showthread.php?t=68811 And this leads me to a question for RamGuy myself...Why would they not be compatible with an Ivybridge CPU and one of the latest MB's. I would think they should be able to use the latest modules just fine, or is it a limitation of the B75 chipset? Which I couldn't find any information on as far as max allowed memory density.

Well, I've already updated the bios to the latest version and I clear the CMOS before trying different modules. And BTW the other modules I tried (fully working) are almost brand new, don't know the density though. I also tried something else: I booted with a single module of the RAM by the other manufacturer, booted fine, then powered off, swapped the modules (without clearing the cmos) with one of my Corsair, and it booted! So I suspect it could be SPD/XMP related... anyway, after clearing the CMOS, it wouldn't boot anymore. And I cannot be in the situation that a lost BIOS setting would prevent me from powering on the system! Link to comment Share on other sites More sharing options...
albedan Posted February 1, 2013 Author Share Posted February 1, 2013 Anyone? RAM GUY? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 4, 2013 Corsair Employees Share Posted February 4, 2013 Sorry, this was my mistake. I misread your original post and was assuming something else. This memory kit should work (with or without XMP) in your system. If other modules work in your system but not ours, it could be an issue with the IC chips on the modules as you suspect with the board. I'd recommend trying another CMX kit (either exchange it with retailer or RMA through us) to see if it'll help. Link to comment Share on other sites More sharing options...

Actually I cannot exchange it with the retailer (in Italy we have the possibility to change items only within 10 days after the purchase) and sending them back to Corsair would cost me more than a brand new kit - or does Corsair pay the shipping fees? I have to say that I'm quite disappointed. Not a huge expense, but the kit is sold as "Guaranteed to work on all dual channel Intel and AMD platforms" (from corsair.com website) - doesn't seem to be true. :sigh!: Link to comment Share on other sites More sharing options...

albedan Posted February 21, 2013 Author Share Posted February 21, 2013 Well... I have to say that Corsair Support simply rocks! :cool:Long story short: in a couple of weeks I've had my modules replaced with a brand new pair of CMX8GX3M2A1600C9. This time the version is 2.12 (Elpida 256Mx8), while the previous pair where Nanya's. And they boot with no problems whatsoever, both at jedec speed (1333) and at xmp speed (1600)! Thumbs up to Corsair RMA Service! ;): Link to comment Share on other sites More sharing options...
fenasi Posted October 22, 2013 Share Posted October 22, 2013 I have similar problems and had showed this case as an example but they said: "We have tested 8.16 on B75 chipset and didn't see any problem at all. The replacement should work just fine. Thank you." Nobody from staff reads ram forums and live help at rma page is always offline. I sent my rams to RMA twice and after that answer; i'm getting nervous. Link to comment Share on other sites More sharing options...

fenasi Posted October 23, 2013 Share Posted October 23, 2013 I have to write to this post because of the answer. I already have my thread http://forum.corsair.com/forums/showthread.php?t=119641 Link to comment Share on other sites More sharing options...
