well done mat.
congratulations.

(my first post in 5 years, so feel honored. )

why the ud7 board?? why not ud9?

There's no GBT P55 UD9 . GBT's top model for P55 is the UD7 .

Hey guys, I just finished some tests with about 25 liters of ln2, so I have some results ready. But I still have to sort things out and for sure forgot a few comparisons, that would make things sweeter. Well, I need a few days more, but meanwhile I got for you the first part of my experiments:

Everest


CPU: 4900 MHz, memory: 2940 MHz CL8-11-9-24-90 1T


CPU: 5000 MHz, memory: 3000 MHz CL8-11-9-24-90 1T

Scales pretty well I guess. As I said, I didn't touch B2B Cas Delay, as it made no difference at all. Windows has a few issues with it, little bit like the R3E "slow mode" on the qpi setting.

MaxxMem @ 4.8 GHz


GTX2 @ Air, 2000 MHz CL7-7-7-18-74-1T, Score: 1466


GTX6 @ LN2, 2880 MHz CL9-11-10-30-100-1T, Score: 1797


GTX6 @ LN2, 2880 MHz CL8-11-10-30-100-1T, Score: 1837


GTX6 @ LN2, 2880 MHz CL8-11-9-24-90-1T, Score: 1859

MaxxMem likes high memory frequencies, so these results did not suprise me. Tweaking the subtimings had some effect too ... better be like that, because it's sooo time consuming . Please consider that the GTX2 was on air and not maxed out for frequency, but rather efficiency.

SuperPI 1M @ 5 GHz


GTX2 @ Air, 2092 MHz CL7-7-7-18-74 1T, time: 8.235 s


GTX6 @ LN2, 2092 MHz CL7-9-8-24-90 1T, time: 8.235 s


GTX6 @ LN2, 3012 MHz CL8-11-9-28-100 1T, time: 8.219 s

Oookay ... not much to see here. 1M likes memory, altough it's not most important. But at these rates it just does not matter. But I guess 32M would scale much more. Ran out of the precious stuff, so yes ... next time!

What is pretty interesting, is the fact, that timings can decrease performance. It seems like if one module is too weak, than the result goes back to single channel (even though it's shown otherwise in cpu-z). For example 1M at 2400 MHz with timings at CL7-8-8-24-74 1T was slower than CL9-10-9-30-134 1T. Altough CL7 is only possible under -90 °C and less.

SuperPI 1M @ CPU: 4.8 GHz, memory: 2400 MHz


GTX6 @ LN2, CL7-8-8-24 1T, time: 8.656 s


GTX6 @ Air, CL9-10-9-30-134 1T, time: 8.594

I also had the chance to shoot some new photos. Please view them here: http://www.overclockers.at/extreme_c...23#post3062423

More to come very soon!

[Turrican]

wow, those are some impressive numbers you got there, well done.

[Hampti]

hehe. mister mem-master mat is back. well done. gorgeous results.

[quake6]

Nice results, but could you test 32m? And what about lower frequency but with tighter latency?

[George_o/c]

He said that he didn't have a chance to test 32M because he ran out of LN2.

Nice results dude, GTX6s seem to be really really strong under LN2

[0skill]

Nice work dude

Well I meant in future... Also on air wouldn't be bad as I/pretty much anyone are interested how are they performing compared to hypers... What is the next big thing in memory OC...

[stevke]

Awesome numbers, good job mat

[Ccaution]

Grats mate - those GTX6's are really sick

Setting those screenshots as a wallpaper on my pc - will probably make it boot faster

[systemviper]

thanks for posting your results, Great Effort!

Its rad that they run that high and im sure they spent hours binning at that speed but for the guys on clarksdale that dont have lynnfield mem controller but have unlocked multi 655k etc. and want a better idea of how how far they go by running them tighter than a nun's c word. would you kindlysee what you can do at cas 6-6-6- next time u get the dewar filled?

would make no sense at all, the IC is not optimized for that.

okay thats why I asked. I never took the time to fully understand elpida hyper. I own a gskill F3 17600 cas 7 2x2 kit and 2 pairs of 2 X 2GB kingston hyperx KHX2000C8D3T1K2 KITS and ive only used on clarksdale imc so I never really ran them at high timing slacked out. just stayed around 1600 - 2100 trying to keep it at 6 or 7 cas. I figured maybe these really high speed bins might also go the other way if you wanted tight and were limited to imc. so nevermind.
I dont even think the hyperx is elpida hyper. they never come close to the F3 gskill kit. asfaik the 6gb hyperx kits were hyper and the 2x kits were something else. So I really think its time for me to get some new blood. I was thinking of getting some new ram for next hdwr purchase so these looked interesting. the last corsair kit I owned was a 2x512 ddr1 3500 bh5. I figured its about time. I'm not in the forefront of memory breaking news so if anyone wants to help me out lemme know. is there some new ic coming up that is going to take over? is elpida hyper the bh5 of the 21st century and I should hold onto them until I have to post in the elpida graveyard thread? nevermind. Next stop graveyard...
I am curious how much time and work goes into binning these kits? what boards they are using for the tests and what cpus? It seems everything is marketed for cpus with good imc like lynfield. I wish there were more kits marketed for clarksdale that dont focus on speeds over 2100 but focus to the number of the beast.

I think I'm looking for something more like this:
Corsair marketing admins pay close attention. I'm only going to show this once.

I am playing with some GTX3's and so far they are so so with my 655K, 2000 7-9-7-24 @ 1.65 with vtt at 1.35, I wish a had a lynnfield with a good IMC. . .
