Corsair Vengeance 1600mhz/XMP not working

[notea]

Hi,
I had been using a dual channel 4GBx2 CMZ8GX3M2A1600C9 v.2.12 for almost 3 years, and yesterday, 1 of them failed, getting BSODs , cant boot, etc, ran memtest and there was more than 10000 errors, so i got a new 4GB stick CMZ4GX3M1A1600C9 v.2.12, i thought it would start without any hiccups, when i went into bios, the XMP option was grayed out, and when i install the sticks separately, everything was fine, can enable XMP, can boot in 1600mhz, but when i put the 2 sticks together, i cant get XMP to work (disabled) and when i manually adjust the timings and up the voltage a bit, it just keeps resetting back to 1333 mhz, what seems to be the problem here?? any help would be appreciated.

Specs:
Core i5 2500K..(stock)
MSI Z77a-g45, \
Seasonic X 750 KM3,
Assorted HDDS
Asus GTX 670 DCII

PS: i tried 3 different versions of mobo bios and nothing seems to work

The XMP profiles are likely different between the 2 models being used, thus why that option is not available. The performance difference between 1333 and 1600 is negligible, BTW.

Most Corsair memory carries a lifetime warranty. I would suggest RMAing (exchange) the matched pair and using the new memory until the replaced memory shows up.

Good luck!

thanks, i started the RMA process, the problem is that the heat spreaders on both the modules came off, so im not really sure they will accept an RMA, meanwhile, since i cant get to 1600mhz, i adjusted the latency to 7-7-7-21 @ 1T (1333mhz), hopefully, it should provide similar performance to 9-9-9-24 @1T (1600mhz).. ran memtest and everything is stable

Understood. Good luck on the RMA!

If they turn down the RMA and they might, try the two good sticks together and manually set the freq, base timings, and then raise the DRAM voltage to 1.55 and set the CPUVTT voltage to 1.12 and give that a try

well i tried till 1.57v and loose timings (11-11-11-28) and nothing seems to work, kept resetting back to 1333

Understood. Good luck on the RMA!

Wow!!, Corsair is so good, thanks for the advice COLGeek, i had a discussion with a Corsair rep, my RMA is approved, i will proceed with it tomorrow. below is my discussion with the rep if anyone is interested


"Justin G: Thank you for contacting Corsair Live Support. How may we assist you today?
You: its about my ticket no 6299306
You: i bought a dual channel kit corsair Vengeance rams 4gbx2
You: in 2011, last week 1 of them failed, and while i was testing them out, memtest failed horribly on one ram stick while the other is fine
You: i thought it could have been my ram slot so i tried testing the slots individually with each ram stick, while doing so, the heat spreaders came off
You: the thing is that i did not know that they were covered under warranty as the shop from where i bought them said it was a 1 year warranty
You: are you following me?
Justin G: Yes. Please provide pictures of the modules for further review with our Technical Support.
You: well, im not finished yey
You: yet*
You: so, since i didnt know that they were under warranty, i applied double sided adhesive on the still working ram heat spreader and repaired it
You: and then a friend told me that rams were covered under a lifetime warranty, and gave me the link to your new support website
You: so, i bought a new (single) corsair vengeance ram thinking it will work fine with the old one
You: found that they cannot run in XMP as they were different versions..
You: so i came here and asked for help/RMA
You: ive also attached a picture in the ticket 6299306
Justin G: We don't recommend mixing memories for that very reason - incompatibility issues.
You: i thought, since they were of the same clocks and speed, and same vengeance series, they would work
Justin G: Unfortunately, it's not as simple as that.
You: ive been using corsair rams from the XMS series and this is the first thats failed on me
Justin G: The IC chips must be from the same manufacturer in order for them to work flawlessly.
You: i also bought 4 XMS2s at different times and stores and they worked fine with each other, thats the main reason i thought this would work
You: and yea they work fine without enabling XMP/1600mhz
You: but running them at 667/1333 kind of moots the purpose
You: so, what suggestions can you give me
Justin G: We can certainly replace the faulty unit for a new one. Please proceed with the RMA process.
You: im a bit nervous about it because the shipping charge is quite high as i live in a remote place in India, and after sending, RMA was rejected
You: mainly because i repaired the faulty heat spreader on the good ram stick
You: are you certain that the kit will be replaced?
Justin G: Yes. You may also want to contact our partners in India, Kaizen Inforserve, and inquire if they can assist you with the RMA locally. You can contact them at IndiaService@Corsair.com.
You: it will actually be faster if i sent to you directly, as the domestic courier in india is very slow
Justin G: Okay. Please proceed with our RMA process then.
Justin G: http://********************* (dont wanna show my address)
You: oh did you check the picture i attached
Justin G: Yes, I did. As long as the warranty label is not tampered with, it should not be an issue.
You: where is the warranty label locted
You: located*
Justin G: On the other side of the heat spreaders
You: ok, you have been very helpful, thank you very much Justin, i will send the kit tomorrow
Justin G: You're welcome!"
