Hi ,
I'd just like to know how burning in worked for you guys . For my part , I went from my RAM hating 3.4v ( thousands of errors per pass ) to loving it ( 4-5 errors per pass ) . I still haven't reached 260 fully stable , but i'm getting there . At 4-5 errors per passes , i'm alot closer than I was before at thousands of errors per pass. I'm still burning in at 3.4v 260 looping full memtest . So how as burning in worked for you ?
Thanks :banana:
at 3.4v 260 i got 196 errors in 88 pass...that good ? :)

Absolutely no success of burning in my VX sticks. And I'm not the only one, as far as I know.

Burn-in did nothing for my 3200s...
For those that are running DFI NF4 mobos, are you actively cooling the area by the 4V VDimm jumper? Once I aimed a fan over that area, the errors in Memtest seemed to disappear. Try it and let me know how it works out for you.

Did you also cool the heatsinked mosfet in the upper right area ? It right by the dimm slots .

For me, active cooling the 4V Dimm jumper area did help me get less errors.
Besides trying to get less errors, the 4V jumper area is super hot. :eek:
So putting a fan over makes me feel mentally comfortable. :)
BTW burning in VXs didn't really help me that much.
For some sticks it did help me squeeze out about FSB 1 or 2.
Currently I can reach 268 with lossened timings,
and 263 with very tight timings.
(which is better :) )

That's exactly the area I'm talking about. The little heatsink next to the 4V VDimm jumper. I have a 80mm Panaflo blowing across the jumper, heatsink, and RAM. Before I did that I was getting a few errors in Memtest. Once I had a little air moving over that area those errors just dissapeared.

I think mine isn't getting enough airflow . How did you mount a fan there ?

I have a big case so I put it in the empty 5.25" bays. It's a 80mm Panaflo U1A so it's a pretty strong fan.

I just finished 7.5 hours of memtest at DDR520@3.3v with NO errors. It has taken awhile, but my VX RAM has gained OCability with time. When I first got it a few months ago, I could only get to DDR490@3.5v, then it went down to DDR516@3.3v, and now DDR520@3.3v. I love this stuff :cool:

No gain for me... it may be memcontroller though

my burn-in went like this: 3.2v @ 200mhz 2-2-2-5 for about 20 hours or so of test 5. No errors.......
went straight to 250 @ 3.2v - same timings - no errors
had to bump up to 3.4v to get 260 going......
i am finding that vx is a strange animal - common sense tells me to loosen timings when errors show up but that sometimes increased my errors - tigthening certain timings made the errors go away....
also - dont trust test #5 - it could loop for ever it seemed but test 6 and test 8 are the real deal.......once you think you are stable in test 5 - loop test 6 for a while - you may see some errors pop up that are your last hurdle to stability!!
what is test 6 and 8 for ram ?

i'll second that 8 finds errors that 5 doesnt
dont use 6 though....4 and 11 finds errors too for me....11 takes forever though, so i'd stay way from it

I just run the complete test through over and over and over.

I just run the complete test through over and over and over.This is recommended by OCZ reps for VX, just FYI.

Yeah but how did it help you ?

It helped for me alittle bit. I went from 257MHz to 266MHz (sometimes 267MHz) on my Neo2 Platinum 24/7 stable and error-free. On my Ultra-D, I've pushed 10x271MHz and 9x277MHz for some 3D benching. I couldn't get to that frequency before with my Neo2, even just for a suicide screenshot.
I've done everything from burning-in to ripping the heatspreaders off to adding a 120mm Sanyo Denki fan. The key to getting the most out of your VX is just making sure that they're adequately cooled. Phase-changed VX anyone?

I bought my 3200 VX about 2 months ago and its been a long and frustrating journey. When I first got them they weren't stable past their rated speed (240) and hated volts, after some burn-in and tweaking I got them to run @ 245@3.2v.
Later I updated to the offical 3/10 bios let it burn in more and used the recommend settings on the OCZ support forum and got to 247@3.3v. I loosened the timings (Trrd-Twr-Twtr-Trtw) and hit 248, tightened them back up ran and memtest #5 for a couple of hours, the errors disappeared. Currently I'm burning in @249, I'm taking this one mhz at a time, my goal is to hit 250.
I've lost count of how many hours I've spent burning in my VX (around 175 hours at various timings and voltages) just to squeeze every little bit of performance out of these subpar sticks. So yeah with my DFI Nf4 + VX, I've learned that this combo is extremely picky when it comes to mem settings and that burn does indeed work.

not this ocz rep:
Hi, you can run at 200mhz, aith 2-2-2 timings using 3.2v for about 48 hours. 24 hours minimum. Run memtest and loop test 5. Memtest can be turned on in your BIOS.
This procedure seems too help when you crank up the volts and speeds later.

I had a similar experience..i ran about 24 hours of 200mhz 2-2-2-8 with 3.2v. I thank cranked it up to 250 @ 3.2v, no errors - bumped up to 260, thousands of errors, 3.3v, hundreds of errors, 3.4v, no errors - so now its doing a super duper burn in at 3.4v, 260 2-2-2-8. By super duper i mean i turned it on yesterday afternoon and left to go back home for easter (i'm in college,so my computers up there). So i won't be back until monday and it'll be burning in all this time, so hopefully when i get back i can push it up to 265-270 with some volts..we'll see :) Overall, i gotta say this burn-in definitely helps :)
