bager4e Posted April 3, 2012 Share Posted April 3, 2012 Hi everyone, I'm just wondering if 1.5 volts will be suitable for Ivy Bridge CPUs. Or to buy 1.35 volts modules for an example CML8GX3M2A1600C9W. I need no more than 1600mhz (CL9). I would appreciate any advice. Thanks in advance, bager4e Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 3, 2012 Corsair Employees Share Posted April 3, 2012 I am sorry but I cannot comment on Ivy Bridge just yet other than to say our Vengeance modules would be the best choice just like the part you asked about.

bager4e Posted May 14, 2012 Author Share Posted May 14, 2012 Hello again, I have 3770k and GA-Z77X-UD5H (latest BIOS F7)and 4 x 4 GB corsair vengeance 1600 CL9 1.5 Volts. 9-9-9-24. (red , high profile) But memory can't run @ 1600 @ 1.5 Volts. I set everything manually , tried with XMP profile - no chance. I run this memory now @ 1333. CPU is not overcloced for now. Everything default. Also tested @ 1345 and there was a memtest86+ error (only one). So maximum error free was @ 1333. At 1600 system can boot , but OS crash during booting.Memtest also is full with errors with these settings. I'm wondering where is the problem and how much I can raise the memory voltage safe ? Thanks in advance Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 14, 2012 Corsair Employees Share Posted May 14, 2012 What is the part number of the modules you have installed? And do you have the latest MB BIOS installed? Link to comment Share on other sites More sharing options...
bager4e Posted May 14, 2012 Author Share Posted May 14, 2012 What is the part number of the modules you have installed? And do you have the latest MB BIOS installed?

Corsair Employees RAM GUY Posted May 14, 2012 Corsair Employees Share Posted May 14, 2012 Oh I see so you are trying to mix two sets to get 16 Gig is that right? Link to comment Share on other sites More sharing options...
bager4e Posted May 14, 2012 Author Share Posted May 14, 2012 Oh I see so you are trying to mix two sets to get 16 Gig is that right? Yes, I bought 2kits , because I want 16 GB ram . So specs on both kits are exactly the same only version number is different (I saw that today). Maybe this cause the issue or one of modules is defective... I can try first to rise voltage. Also until now I had no time to test them separately. Link to comment Share on other sites More sharing options...
bager4e Posted May 15, 2012 Author Share Posted May 15, 2012 Update I have tested kits separately @ 1600 9-9-9-24 , 1.5 Volts. 1. Kit ver 3.19 in slots 3 and 4 (dual channel) - - memtest 86+ half pass -no errors (*with 16 GB on half pass there was many errors) -. OS can boot , also i've run some heavy tests there was no crash or restart. Seems to be this Kit has no problem. Also need full memtest pass for confirmation but later. 2. Kit ver. 2.12 in slots 1 and 2 (dual channel) memtest86+ - one pass - there is a one error for now. Still running. maybe slot issue (1 or 2) or defective module, but still there is a little information to conclude. I will try to run Kit 3.19 @slots 1 and 2. And also full memtest @ slots 3 and 4 tonight. Link to comment Share on other sites More sharing options...
bager4e Posted May 15, 2012 Author Share Posted May 15, 2012 @ 1600 9-9-924 , 1.5V Kit ver 3.19 in slots 3 and 4 (dual channel) - there is no errors - (3 passes) but kit 2.12 - has different errors - random (in different passes also different tests 4 or 6 (memtest86+ ver. 4.20) I have run 3 passes , first pass was withouth errors pass 2 - error at test 4 (one error) pass 3 error at test 6 (only error) when I test both kits @ 1600 - there is many errors @ (test 4 and 6 again). So seems to be the problem is with kit ver 2.12. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 16, 2012 Corsair Employees Share Posted May 16, 2012 I would suggest you find another use for these modules and purchase a quad set of modules that are tested and guaranteed to work on this platform. Link to comment Share on other sites More sharing options...
bager4e Posted May 18, 2012 Author Share Posted May 18, 2012 I tested this set on another pc - also errors. I returned them to the supplier. Now I tried with 16 GB ( 2 kits again) but low voltage memory - CML8GX3M2A1600C9W. Tested and there is no problem - working together 16GB @ 1600 9-9-9-24 ..1.35 Volts. This is the best option for me because I have large cooler (noctua NG-C14) and now I can use both FAN's So I think issue is resolved ( i hope).

Corsair Employees RAM GUY Posted May 19, 2012 Corsair Employees Share Posted May 19, 2012 Okay great news and sorry but mixing sets can be a challenge. Link to comment Share on other sites More sharing options...
MaFi0s0 Posted May 20, 2012 Share Posted May 20, 2012 My P8Z77-V motherboard says intel specs just say not to exceed 1.65v but thats like how they say not to exceed 1.35v on the CPU, theres probably headroom above that. My new bios runs memory speed up to 3000Mhz too. Link to comment Share on other sites More sharing options...
