I have this RAM kit. Used it in my 2P for around two months, but it didn't match my board, so I picked up some blue heatsink g.skill off a fellow ocn member.

I'm using half the kit right now in my x79 rig, but am just curious what is this RAM kit worth these days?

Thanks.

What are the 5th thru 8th digits of the serial numbers (xxxx5678xxxxx)?

Based on the timings, I'm guessing they're Hynix IC's, but the serial number would help confirm; asking because the IC's used influences the value of the sticks....

Also, do you know how well they clock, or how tight the timings can be run at stock speed/volts? Better clocks/timings at stock volts generally means a premium, how much is variable.

Assuming they're plain-Jane, vanilla sticks, with Hynix CFR IC's (from Spring '12 or later), then I'd value them at around ~$225 shipped.

If they're Hynix BFR IC's, I'd say ~$245-255 shipped.

If they're early CFR IC's, it would range from ~$230 and up depending on their capabilities.

Of course, many people have not had a lot of luck running 8 DIMMs filled with X79, as you know it's very dependent upon the CPU IMC, so just as an act of good faith I'd suggest recommending that any potential buyer try and see if he/she can't borrow a few sticks from a friend to test whether or not their processor can even cope with 8 DIMMs filled; it would also save you troubleshooting headaches that would arise from someone buying them and the sticks not POSTing with their CPU. Just a suggestion, though

Thanks for all the good info. They are xxxx2400xxxxxx.

I've just ran them at 1600 mhz on my 2P (limited by the board), and the XMP (1866Mhz) profile when I had half the kit in my x79 rig.

Same as my Ripjaws Z 4x4GB 2133 9-11-10-28 kit, the xxxx2400 part, which means they're most likely early CFR's or possibly (if you got them soon after release), BFR's.

I can speak only for my kit, but it's far more capable than the (already impressive) stock specs let on... With my 3930K, I can run them up to ~2600 with 10-12-10-25 1T timings and just 1.675v vDIMM, although I haven't been able to find a way past the "wall" my SB-E chip hits at that speed, which may well be its limit.
With my 3770K, however, running two of the four sticks, they'll clock to at least 2666 10-11-10-25 1T (keeping good timings), but I've gone as high as approximately DDR3-2788 10-13-12-30 1T with 1.705v.

If your sticks can hit 2133 9-11-10-28 1T, they're very good, and based on the way G.Skill bins their memory, I'd bet those sticks will run the "one-bin-up" speed without issue.

As far as whether BFR or CFR, what is the manufacturing date (the first 4 digits of the S/N = Year & week)? That might give you a clue. A 2012 date almost assures CFR and an early 2011 would lean towards BFR. I would be inclined to vote CFR.

...and the pricing that you've been getting is about right...$225-$235, shipped, would be my valuation.

1243, so Oct 2012?

That would be 43 week of 2012 date. Basically Oct 22-Oct 28 2012. So Hynix CFR.
