Anyone have experience with Corsair 1866 Vengeance modules

[Dirk Diggler]

on a CIV or CV. Im looking to either tighten the timing or looking for some assisitance when I move past 1866 Right now any changes I make at 1.65vdimm results in a no post currently at 1874 a 9-10-9-24-1T.

More VDIMM? Vengeance are not certified on AMD.

More than 1.65 they are rated at 1866@1.5, damn I knew I shouldve gotten the Ripjaw X cas 7 1600 sticks

You can always sell them, I'm sure someone will buy them up quick.
(However, you need 100 posts to post in the FS/FT section :d)

Thanks I think that is what I will do I will list them on Amazon and move them for the GSkill sticks

I finally checked the manual and they are QVL'd

That is interesting.

What are your settings?

CPU-Tweaker open to SPD, CPUZ CPU/SPD/RAM and a list of voltages?

i have 8gb kit on a p67a-ud4 b3.

work well with xmp profile @ 1.5v

I am running them downclocked right now because even with 1.67 volts running spd timings it still failed prime after about 5 minutes. I am stressing them with prime downclocked at this time for almost 2 hours without incident at these clocks. My cpu is 1.518 in the bios and my CPU/NB is 1.33. Ive tried bios 506 and this beta bios to no avail same results

We just received these from Corsair and you need to run them at 2T. I will have some additional settings on the CVF next week once we complete testing on them.

I have the DDR3-1600 9-9-9-24 kit. They run fine @ 1562Mhz 8-9-8-24 1T and also 1954Mhz @ 10-11-10-28 1T, 1.65V
Both configurations are memtest86 and 8hs prime stable.

The 1866 kit must be the same, so...

Have you set any secondary timings (timings other than your normal CL, tRCD, tRP, tRAS, tRC) in your bios?

Try setting DRAM READ to PRE time to 5, RAS TO RAS Delay to 6, WRITE TO READ Delay to 5, CAS WRITE latency to 9, Write Recovery Time 12. Ref Cycle time of 110ns, READ TO WRITE delay at 5 and WRITE TO READ at 3.

Those are simply guesstimations, they might work better/worse for your kit, I'm not sure. You can try changing one at a time, though if any of the numbers I posted are tighter than what's already set, don't change it until you gain any headway.

Nope everything was left at auto I do know that setting the Ref cycle time to anything other than 160 results in a no post. Ive tried that before and couldnt get it to post even with upping the voltages and if it did post programs started crashing in Windows once the desktop loaded. I am starting to feel these sticks arent really compatible with the board or need a little extra TLC to get running at 1866.

Run the kits at 2T, if you have version 5.1 on the memory, it is hynix that has been binned to get to 1866 C9 2T and 1T will be difficult. I have four modules here and three will not run at 1T stable or even POST at times, so far they have run at 2T for the last four hours without a hiccup. I will have tuning suggestions with this memory kit posted next week.

Thanks you for the feedback. I will try what you suggested.

Memtest fails test 7 horribly over 30k errors and still going before I killed it
Memtest @ 1600 at 1.60 and 1.65 failed at 9-10-9-27-41 2T
3 sticks failing memtest @ 1600 2 Blue Vengeance 1866 and 1 Black Vengeance 1866. Only other things is for me to test a different vendors kit to make sure it isnt the board I am out of ideas......
@1333 memtest complains about "Unexpected interrupt halting cpu0"
