i have two very good ddr3 kits, trident x 1200(1333), klevv genuine 1466(1600-1650). they do well clocking higher but struggle with tight timings/lower clocks. do well with hashwell though.
looking for ddr3 kits which can do 1000-1150
timing like 7-10-7-24-1, 8-10-8-24-1 or even 8-12-8-24-1 etc.......
g.skill pi seems to be very good but very expensive on ebay.
looking for a decent kit cost around 40-50 usd....

That's gonna be hard to find since Intels prefer RAM MHz over timings but tighter timings can't hurt either. PSC chipped sticks are what's said to do best with those in this regard. Just beware of kits that have been thrashed to no end then put up for grabs. I know the kits I have CAN run as you've described but for some reason they will only excel in my AMD setups, not in my Intel stuff.
There are several Trident kits that do well with SB/IB, those would be the sticks to find if you can. Tridents with a stock CL9 with these is probrably close to as good as you'll find for the speeds you want, several Trident kits with that have been known to clock high and tight, most CL8 sticks probrably won't be of a high enough PC rating to hit the speeds you're looking for but they are out there somewhere. I'll keep an eye out and let you know what I find if I see a set.

I have both, two sets of Tridents and a set of PI's. My Pi's are exactly like those and of the Tridents one is the same PC rating, the other is higher.
Al I can add is be sure what you find is dual ranked because some aren't - The Tridents I have like those in the pic aren't, the other set is.

This is what to look for K. These are 2 of a set of triple channel tridents. The first 4 digits of the serial number 1008 is the date of manufacture the first 2 digits represent the year 10 = 2010, the second 2 digits represent the week of the year 08 the 8th week of 2010 if they were manufactured in 2009 it would be the first three digits. The next four digits are the IC manufacturer 1040 means PSC that is what you want. There were quite a few of these triple channel sets produced and can be had fairly cheaply sometimes, these will do 6-9-7 @ 2000 Others to look out for are. G.skill PI. G.skill Eco. G.skill Flare. If they are PSC chipped they will have the second set of 4 digits 1040. Here is the G.skill list of serial numbers. www.xtremesystems.org/forums/showthread.php?283666-Figuring-out-G-Skill-s-SNsAnd this is the list for Corsair DDR3 forum.corsair.com/v3/showthread.php?t=68811 |

triple set or not dont mean jack shit, you only gunna use 2 of em, theres just a choice of another if it ranks up good enough, or if any of em rank up, you can can get psc that have been hammered and arent worth nothin, same as all hardware , you can buy 10 sets and get 1 thats any near good or none and try again for another

PI Eco and Flare dont usually come in triple channel sets.
Triple channel sets were specifically for socket 1366 and are just another option to look out for.

Triple sets are good in that you have a spare just in case a stick dies, ruining an overall "Good" benching set. Had that happen to a couple of them and if I'd had the third stick it woudn't be as bad since then I only have one stick of what I want making the remaining stick useless. I also had a few triples that did save things, one stick started to die and the backup stick allowed me to keep going instead of having to immediately dig up another set like or close to it. My AMD blacks (CL8 8-8-24) are one of the sets I refer to, one died and the other one is fine but it's useless on it's own and I don't have another like it here. I also have a set that's kinda similar (CL7 7-7-21) and one of those also began to crap out BUT I had a third stick onhand preserving the ability to run sticks like them and I'm still going with them, these sticks have given me some good PI runs with certain setups. However you are right in that triple sets can't be ran as a "Triple" setup unless you're running a board that uses them in this way and yes, there are a few that do. Overall I too would not just grab a triple set unless the price is right but having the backup stick isn't a bad thing either - I guess it depends on how you wanna look at it.... And if you have a board that can use them in that way.  EDIT: Spotted this set and they are PSC chipped sticks but make sure they are what you'd want and the price isn't too high, seems like alot of sellers are jacking up the prices to recoup some of the investment cost of getting DDR4 for themselves: www.ebay.com/itm/G-SKILL-Ripjaws-Series-8GB-2-x-4GB-240-Pin-DDR3-SDRAM-DDR3-1600-PC3-12800/132509776219?epid=114517010&hash=item1eda32b95b:g:HVIAAOSwtBdaicRz |

I have got 2 triple kits of g.skill pi 1600 (F3-12800CL6T-6GBPI...6-8-6-20 1.6V). All of them can do ~2400 8-11-8-28 1.75-1.785v (quad channel on 3930k@5.0+ strap125). Also they can do 6-9-6 2000++ on 2*00k. I understand that they are expensive...but they are worth it. It will save Your time and some extra money in the future(next cheaper sticks). I would prefer not buying PSCs (****CL*TU-*GBPI)... Best Regards  |

Have a set of Patriots 3x2 PV236G2000LLK, 8-8-8-24 1.65v that I picked up when I got my first X58 setup. Run all day at DDR32000+, 7-7-7-21 1.72v so gave them a go with SB fist time I've had software mem clocker and ended up at 6-7-6-19 1T DDR32000+ 1.72v windows XP post. Much better than the G. Skill Tridents 9-9-9-27 1.6v and Corsair Doms 8-8-8-24 1.65v kits I have at the same speed. Although did better with a 2x4 kit of Klevvs with H265 than the 2x2 kits were getting with the G465 I was using.

Try to find a good kit with Elpida Bbse ic's. They are quite common and can do 7-9-7-21 @ 2133 pretty easily. I found my Samsung kit (2x4 Tridentx) also very good. However the main timings not as impressively low as some other types but subs can be tightened much much better.

TRIDENT X 8-10-10-18 @ 1105. that's good. i can do only 9-11-10-21 @1100-1160. i can't do even 9-10-10-21 with my TRIDENT X kit. original timings are 10-12-12-31 @1200. can do 9-12-12-24/10-12-11-21 upto 1250.(on hashwell and amd fx) it's doing ok on x265 , xtu but real test is spi 32m. it's very slow there. |

Are those TRidentx single or double sided sticks ? It was made with Samsung and also with Hynix ic's. |

Those are 2x8 Gb sticks, I don't really know too much about 2x8 kits. Made a screen to show, why these high density samsung kits are so good. A cpu-z memory tab shows only the most common main timings but the "trick" is under the surface. Look that subs, some of them are nearly as important as Cl for fast spi32 runs. Ok, a very good 2x2 kit can beat this, but maybe a bit harder to find and also (not even just a bit  )harder to keep them running flawless through an spi32 run.  |

My ram is showing part no as F3 2400 C10-4GTX(The ram in the pic shows F3 2400 C9-4GTXD.
normally i change only TRFC AND TREFI.
this ram can do TRFC around 162 (above 2400mhz), 148 (2300mhz), 128 (around 2000mhz)
TREFI original is around 8340 and change it to around 6240.
never played too much with other sub-timings. will try to change some sub-timings & see if it helps.
only time i remember changing lot of sub-timing is for x265 4k & xtu celeron G470. that did help a bit but done randomly.

I will let you in on a secret there K
TREFI stands for refresh interval the higher the number the better.
Ram cells are just capacitors the charge has to be refreshed frequently.
The lower the number every 6240 clocks it will refresh the ram, ram cells cant be used while they are being refreshed. the longer time between the refresh interval the more it can be used.

ddr4 i have a b-die that likes TREFI 65535. if i leave it auto it's any where between 8000+ to 14000. but when overclocking higher 3700-3866 on my maximus hero, it's only stable with TREFI 65535. Always keep it there.
don't know much but i understand higher TREFI gives more stability definitely @ higher clocks.
now as i have gone through more details, higher TREFI helps improving performance.
this lower TREFI on ddr3 is basically picked up from auto when system set it at lower clocks & stable, so i just used them at even higher clocks. now i can try max TREFI possible and try to lower TRFC & some primary timings to see how it goes.
