fastest ambient Superpi 32M!
-
I had always been wondering what that 5.5 valid 930 did in 32M...
-
711 fsb 1M kinda tells me there is much more to come, given that you already showed off 710 fsb booting... Excited for what is coming next...
-
Have you tried any of the really low end gigabyte p45 boards too? I wonder if they can get anywhere close to 700 as well...

Try e.g. hotplugging dimms, you might be surprised what readouts one gets
oh there are also platforms where you can drop channels in such a way all tools but taskmanager fail to detect how many channels are currently populated (making a certain tc stage a couple years ago quite pointless...). Can see in Taskmanager(due to capacity) and bios only one out of 3 sticks is detected, yet cpu-tweaker and cpuz detect all 3 channels as populated and running at high frequency...
-
so old rankings will be impossible to beat with CPUs that are impossible to validate as allcore with HT on? I see CPUz valid just like memory frequency, only goal is CPUz showing the frequency in the valid, no matter how that is achieved. Off course having a seperate category for allcore + ht valid would be fine I suppose.

MX-5 actually good paste on Ln2?

Dat Vcore
Wonder if vcore or vdimm are higher now

Apparently c7 is broken on platform so basically a matter of can you do c8 tight or c6
thats the first time I heard that... just a pain to get running on many x48 boards.

Does anyone here have any idea where to get LN2 pot for cpus and gpus? The only thing I found is the kingpin shop. But there are only CPU pots there. I would like to try dry ice first, but without hardware it's just bad ...
https://bartxstore.com/product-category/extreme-cooling/
https://www.burningoc.de/reaktor
https://shop.bitspower.com/index.php?route=product/category&path=68_356
I think those are the only sellers currently, but its always an option to try finding a used LN2 pot as well

One question, do you use SPD Tool? Or it's something more sophisticated piece of software?
I just use RWEverything since it is all you need to modify for lower density is Byte 4 and Byte 5 with ddr3 and its the simplest to use (in my opinion) for basic spd mods like that.
SPD Backup is obviously the first thing to do once you modify sticks like this!
SPD mods are underappreciated sometimes

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.

What about jedec ram in chA and problematic hypers in chB/chC?
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?

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!

Will be a challenge. To post, try skew a2 of "advance 350ps" and skew b2 of "delay 75ps" (delay 0-100 is the range to try). Without these skews my system won't even post.
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?

more like this!

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 1.9VRetested 7-7-6 32M and 7-8-6 1M again, now running much better.
