While I figured out how to get the sticks “running” again, I’m anything but satisfied with the solution I found. I noticed while experimenting with the damaged 1866c7 that it wouldn’t reliably run windows 7. @Digg_desuggested it might be accessible memory related - so I reduced the available memory on the sticks via a modded spd to 1GB per stick (512mbit with DR - not losing any efficiency in the process). Suddenly they booted windows 7 without issue, and even work again on the R3E (R3F not tested yet but I’d bet it works there too). HOWEVER, it appears that I now need a bit more voltage to stabilise the sticks as before, maybe losing 15-20MHz at CL6 with same volts. Not the solution I was searching but better than a dead stick at least. I’ve yet to test mixed density for efficiency, I hope I do not have to flash all my sticks

Disabling memory recheck with a working stick+damaged stick results in the same behavior as with the jedec stick; windows 7 still bluescreens on asus x58 with the problematic sticks.

just tried this. With normal sticks, the board boots straight up. With these, it loops training 3-5 times but completes post. In bios, all 3x2 gb get detected (or 2x2 if only testing with 1 of the problematic sticks). Once xp is booted, cpu-tweaker detects triple channel yet only shows channel A. Win 7 64 bit bluescreens a couple seconds after loading desktop, with both configurations. OS works normal with only the jedec stick. I have not yet tested performance in XP (and won’t be able to today sadly) but I am not sure what to expect.

Hello, I recently wanted to finally properly test my 2000c7 Hypers and decided to try run them on my trusted R3E with W3680. But one of the sticks refused posting - first thought was obviously shelf death or transport damage. With cleaned contacts exact same issue. Swapped to R3F with different CPU - still unchanged. Moved to x58a-oc - suddenly stick works perfectly fine. Compared SPD with the stick thats working correctly, no differences. Just for fun decided to dig out the DOA stick of 1866c7 I got in a recent purchase - and off course, runs 32M as as it should on its own as well as with other sticks, even at >1000mhz 6-7-5-20. Tried both sticks - on their own and with other sticks - on asus again, and no luck getting them to detect, always no completable post. Now finally went and grabbed P5Q3 deluxe just to see if the issue is asus x58 or asus in general, and on there both weird sticks run flawlessly. Beyond flashing a completely different SPD and different bios versions (which I doubt given the issue shows with 2 different boards) I’m out of ideas. Has anyone had this before and got any ideas how to go about fixing it? -Ground

CPU or board limited now? Curious if you'll push it further and if so how much :D

Sale cancelled. Can be closed.

desktop gtx 480s are all 384 bit.

what temperature? 6.4 with triple channel sounds pretty nice :D

Highest clocked 32M ever? You are just going crazy with that chip!

Yes! I noticred the A2 skew one but failed with getting B2 to run high frequency at the same time. Will try that combination later. Thanks!

Great score! But why aren't you pushing uncore?

Small pricedrop on the 1866c7s. Open for trades for strong x58 chips. Added a couple more tests. If there is something specific you want tested with this kit I can do so, IMC I have here is strong enough to run anything hyper can run with relative ease. 3x2 GB 1866c7 75€ OR 2x2 GB 1866c7 45€ Selling a triple kit of 1866c7 Corsair Hypers. These sticks are from two different kits; one stick is an older "best stick of a kit" I am fine without, the other two are the living sticks from an average kit (third stick was DOA, can include it for collection value if you want). These sadly struggle with stability at higher frequency as far as I can tell, since I couldn't manage to complete a run of 32M at 1050 7-7-6-20 at any voltage, nor 1100 7-8-6-22. The 0936 stick is stronger (1000 6-7-5 1.95V; 1090 7-7-6 1.85V) and has no such scaling issues. 32M 1000 6-7-5-20 2.0V 32M 1000 7-7-6-20 1.68V 32M 1052 7-7-6-20 1.85V 32M 927 6-6-6-18 1.95V not minimized, just checking max freq 6-6-6-18 32M 8M 841 5-6-4-20 2.05V not minimized, just checking max freq 5-6-4 8M 1M 1052 6-7-6-20 2.05V 1M 1188 7-8-6-22 2.0V Valid 1272 8-9-8 1.9V Retested 7-7-6 32M and 7-8-6 1M again, now running much better.

Added a kit of 1866c7 Hyper. Open for offers or trades for strong 1366 chips.

There you go

broken 3:5 ratio :( 724 real

@Gigelzhad one working that he broke and a dead one, he has info on them

its funny how this score is done with CPU + mem on LN2, yet the actual FB-DIMM Record, done by Christian Ney as well, is done with everyone on air https://hwbot.org/submission/2944273_christian_ney_reference_frequency_0gu083_425.36_mhz

BDBG can do the same PSC can assuming you bin enough of it.

timings look like elpida or Psc to me, and given its kingston I'd recon its BBSE or BDBG

and with memory at meme timings lol

weird definition of a sucking board :D

At least some PSC was Elpida based, not sure if they just used licensed designs or just packaged Elpida themselves / marked the chips themselves. http://abload.de/img/_57l9utu.jpg

do you have another SS for nb? could be enough to push you over the fsb walls...

benching at ddr2 774 5-5-4... crazy, I don’t believe I’ve seen that before!
