I have 16gb of Corsair DDR3 XMS3, PC3-12800 (1600), Non-ECC Unbuffered, CAS 9-9-9-27, 1.65V
When Running windows I sometimes get what looks and sounds like lag?
I manually set the ram timings in the bios as 9-9-9-27 just incase they were being wierd, which helped but its still doing it from time too time and can be really frustrating when playing games, or watching videos.
My question is 1) why is this happening?
and 2) should i try pumping more voltage into the DRAM? and also maybe change the latency setting too something like 9-9-9-24 ?
Thanks
describe your issue in more detail, the lag

Ok so basically when your watching a video or playing a game the image will freeze and the sound will repeat itself and sounds like transformers, this happens in intervals of about every 10 seconds say.., This has happened before but instead it froze completely and the sound continuously sounded like a dying Megatron and then finally blue screened.
full specs?

I'm betting it's your overclock, is it stable? Run Prime95 for 10 min and post if there's any errors or warnings.

I had ran prime for a healthy 5 hours before post with no errors. In 99.9% it's a ram issue. I have now set my latency settings too 9-9-9-24 and so far so good. I'm considering upgrading the ram in the near future. I want to spend around £100 - £150 on 16gb of something better and faster RAM! Any ideas??
okay then run memtest
[editline]10th February 2012[/editline]
and your RAM should be at 9-9-9-27

Ok so i decided i would take out my ram and read from the sticks themselves. never guess what i found! lol, 9-9-9-24 latency on all 4 sticks... PALM TO FACE i also boosted the dram voltage up to 1695V did mem test for 1hour 30 mins all fine.. so far. :)
The maximum memory voltage the Sandy Bridge CPUs support is 1.575v. Using 1.65v RAM will likely reduce processor longevity, and get worse the higher you bump the voltage up.
Why do you have 1.65v ram in a SB build?
Sounds like a bad overclock to me...
Yeah bring down your over voltages and overclocks and see if it helps any, to be honest you are not supposed to run 1.65 voltage ram on a max 1.5 ram capable CPU.

I was never aware of this! :0 I thought that it was down to the motherboard ( face palm ) ok so my plan is either. A) buy new ram? B) wait for ivy and get that because mine ( i7 2600k) has been through some harsh OC ( 1.65+v which I know is ridiculous! Lol) or C) wait for ivy. And buy new ram too.
i would say remove your wireless card, i had this problem, removed the wirless card and it was fixed instantly with no problems

All Intel CPUs have historically had the memory controller integrated into the North Bridge on the motherboard up until the end of the LGA775 socket (Wolfdale core.) Starting with the Nehalem architecture (LGA1156/1366), the memory controller was moved onto the CPU to reduce bus contention and improve performance.
AMD has had the MCU on the CPU for far longer (back to the socket 754/939.)
Sandy Bridge-E is going to have the same memory voltage problems as the current SB chips, so you still won't be able to use your RAM on it. Just buy new RAM with a working voltage of 1.5v or less. I've seen some LV and ULV DDR3 with working voltages of 1.35 and 1.2v which would also work.

I found that this fixed my problem:
Changing the turbo limits
changing the voltage settings on the DRAM and PLL
making sure all timings of ram are set too 9-9-9-24
De-fragmenting all drives
Doing a Windows disk error check on startup. ( fix automatically enabled )
Disk cleanup
Un-installing unnecessary programs e.g Adobe Air
Overclocking my 2 gtx 570's ( stress tested for stability )
And finally fixing any registry errors.
Last final boot up.
Runs as smooth as Chuck Noris's hands!
