damn I want it very nice Hiwa !

[over@locker886]

Very nice mate, but what can do with aircooling cpu? Not everybody have phase cooling for 24/7

[hiwa]

Very nice mate, but what can do with aircooling cpu? Not everybody have phase cooling for 24/7

if we use cpu aircooling we can't see the memory limit caz cpu block us first, so we need to give it a bit cold to see the memory limit.
i think no one have a cpu can handle 2500 memory 24/7 same for 2400 and 2300 i'll test cl7 and 6 later just to see where they can go for dailyuse users

and later i will post Gskill PIS 6gb 2000 6-9-6-24 kit test for X58 and P55 platforms, will test 12gb same kit too
so please give time to do all of them

[stasio]

On the G.Skill site is also latency 9-11-9-28-2N,
on the box and sticks 9-11-11-31 and third XMP show 9-12-12-32.
Confusing.
Btw,nice sticks...IC?

yes i see, will ask Gskill for sure
but who care if they can get 8-11-8 2500 ?

IC should be PSC like other lower freq kits from GSKILL

[ultraX]

wow, amazing!!!! U R the best HIWA!

[zsamz_]

real sweet stuff there Hiwa

[PcCI2iminal]

nice stuff M8

Exactly, I fully agree with you mate. Nobody can run 2400MHz+ memory for 24/7 with CPU on air, IMC gets pwned big time 'cause of high VTT And even if you can, your setup won't last long For example, with system on FULL AIR (both cpu and mems) I could memtest fully stable @ 2450MHz 9-12-9-31 @ 1.76V. But IMC Voltage was 1.53V... Too high for 24/7 from my point of view.

Great job man! With the cpu on phase, IMC gets some proper cold and helps rams go sky high

[hiwa]

thanks guys, i'll update this afternoon
have some number to show u guys

[hiwa]

some tests
Mem still on air

quick IMC testing



1371 8.11.8.24 1.66




let try tighter tRCD

32 2400.8.9.8.24 1.66






let push a bit higher 2800 8.11.8

[radaja]

2742Mhz cl8,thats just so sick.
hiwa,great work as always

[hiwa]

Fisrt LN2 run on Asus Board and PSC ICs new GSKILL memories
the PSC as we know coudn't run low tRCD, i amazed when i see they can run this good under cold, just give them cold and go for crazy frequencies

i ron memoriy under cold with a lot of mainboards before , but this P7P55D-E deluxe was the best memory clocker i ever seen, damn stable and benched +3 hours under cold memory (-100/-150) , ICE everywhere but still went strong and boot everytime into the window....

here we go ..

32m 2200 7-8-7- 1.79



pi 2m 2312 7-8-7-24 1.79



32m 2140 6-8-6 1.69


32m 2600 8-9-8 1.69





Some setup pic

[BenchZowner]

Not bad man, not bad at all

[Leeghoofd]

nice work Hiwa, your giving Frank's ram a good run for their money

[illuminatiASUS]

Awesome Memory, Awesome Overclocker and Awesome ASUS motherboard = PURE AWESOMENESS!!! - HIWA outstanding job and kudos for all the time and effort. Glad to hear your time spent on the -E Deluxe has been well spent and enjoyed.

[George_o/c]

SPi 32M @ 2600MHz 8-9-8 with only 1.69V! That's outstadning, congratulations Hiwa
More voltage didn't help?

[Kentaro]

Really amazying. I thought TRCD is the bottleneck for PSC, and I was so surprised to see the 2300 7-8-7 timing.
Does it need any subtiming adjust?? Some people have givn the memory undercold but only this one can run at low TRCD.

[hiwa]

nice work Hiwa, your giving Frank's ram a good run for their money

for the low price memory the performacne and frequency are AWESOME & incredible

here is with cpu and mem on air for daily use users

1913 6-8-6-24 1.64 is good enough for any daily use I7 860 user no ?

tested again with OLD PIS PSC memories today,i just wanted to see how the board is, got +70MHz higher than other boards would love to test this board with clarckbar (still have my gem 670 @ home)

SPi 32M @ 2600MHz 8-9-8 with only 1.69V! That's outstadning, congratulations Hiwa

i wanted to show low Vdimm and high frequency, please stay tuned and wait for other Ln2 runs

the NEW PSC IC is aweseome and very stable with low tRCD,i should just set tWL @ 8 (def is 7) nothing change in performance with higher tWL
tWL must be CAS -1 so for CL8 i should set 7 but max stable was 2568 between all tests air/ln2 did with B2B disabled


QUICK 2508 9-9-9-24 1.66 testing also LN2



so we can set tRCD same as Our Cas latency on new PSC , it's

[hiwa]

Another quick LN2 -180

2000 6-7-6-24-88 1.70 32m stable


2065 6-7-6-88-1.70 1m

[ihog6hog]

Wow

[Kentaro]

WOWWWW!!

This kit looks very fun. I will be looking forward to seeing some 3GHz with dual channel.

[hokiealumnus]

First off, great clocking hiwa, those are some excellent sticks!

i think no one have a cpu can handle 2500 memory 24/7 same for 2400 and 2300 i'll test cl7 and 6 later just to see where they can go for dailyuse users

Not necessarily. I run my 870 at 4GHz / 200 BCLK 24/7 with only 1.4vVTT. Using the 12x multiplier it runs the sticks at their rated 2400 / 9-11-9-28, stable as can be. The CPU is on water, but still not sub-zero. It's not just software stable either. I beat the snot out of them with an Ultra-X hardware RAM tester (check out the review here). For softare stable, I can drop VTT down to a comfortable 1.375v.

Anyway, just saying 2400 is possible 24/7 without issue & without damaging voltages. 2500...that's a lot tougher.
