Thuban + Hyper speeds + D9 vs PSC?

[I.nfraR.ed]

Agree, it requires a lot of time and efforts, there's no magic behind it. Skills required as well. I just didn't have so much time during the competition, or didn't push hard enough. I was cgetting closer to completion when suddenly it started to fail almost immediately and couldn't get it to that level anymore.
I spent more of the time for Deneb, trying to match Crosshair III performance.

Not really full tweaked runs, room for improvement, cpu speed was capped at under 4.5 for a contest. Both chips have more in them.

What about 1900+ 6-6-6? My sticks aren't gold but I'm pretty sure if I got them cold I'd be able to get somewhere around there. 6-7-6 doesn't scale much more than 0 Mhz due to my inability to figure out which sub does what

My problem I believe with getting clocks higher are the secondary subs, I now believe the reason my other set was stuck at ~1700 C6 was because of the auto set subs, though I've got to experiment on that a bit.

Thx Infra for your advice...Now Im benchamrking at benchtavle and I have my personaly record. Its crazy,crazy CPU clock! Im shocked how can change with only 2 cores enabled. But still I have problem with RAMs, this DOminators cant tighter timigs

Put that 200Mhz more in the NB and I'm sure the hypers will be 2s better.

Actually I'm going to go balls to the wall and say Hypers can = PSC on Thuban, though you can not at all prove they are faster. If you dont care about voltages on your Hyper kit and they DO scale above 1.7v unlike Corsair's kits (I believe this has to do with PCB and cooling more than the IC's) then you may surpass PSC if you push enough rediculous volts (Upwards of 1.75 to 1.8v).
I mean, it comes down to individual sticks, speeds, abilities of overclocker, board efficiency, dirty OS, clean OS...Hypers at 1870 6-6-6 are going to be very close to PSC at 2190 7-9-7. As far as all Hypers doing that? GTX2 I'm sure could do 1860-1900 6-6-6 easily, I can probably eek out about 1850 from my kit.

You can take 3 seconds and add them to the 965 result due to Deneb being faster CPC, then take them (possibly plus some) right back off for the lack of NB speed between the comparisons.

Thuban =/= Deneb.

Quick question for some of you competition clockers....

Whats the best/quickest way to test ram timings in windows (on the fly)?
I've been using P95 Blend with 3Gb of mem (4Gb kit).

This seems to work pretty well without crashing things too badly, but I wondered if there may be a better way.

Thanks..... Dave

Did you read what i said................

With a tuned run they are 3 secs slow............also same exact clocks on thuban loses 10 secs with hypers.

That hyper run is with deneb

Your very stubborn and not willing to listen so heres all things equal.

deneb http://www.hwbot.org/community/submi...in_40sec_422ms

Thuban http://www.hwbot.org/community/submi...in_50sec_281ms

Hey chew*, would you mind running that PSC 7-9-7 run with a bit slower speed, say something like 4400 CPU/3300 NB, in that area? I've been trying to match your 965 and your 936 6-6-6-18 run but I ran out of CPU about 4450.

I'm (very) desperately trying to get sub 15 atm

Maxmem is a horrible thing XD

I ran with less than 4400 cpu speed here.

[BeepBeep2]

Like I said I can't get my NB past 3350 (basically that same run with 1 lower NB divider is what I'm looking for), I could probably do 3400 for 1M.
Tomorrow night I'll install XP and run waza/maxmem to see how close I can get otherwise. My install is so dirty atm I can't use maxmem and have enough free memory for 32M.

Ok guys, after

Corsair XMS3 PC12800 C9 - 8GB


and
A-Data 1866+ XPG V2.0 - 4GB



I am now trying with
G.Skill ECO PC12800 C7 - 8GB


What to say:
C6 1T is a no go, even with 1.65V (as in the screenshot) - UPDATE: It seems it was the -18 the problem. With 20-24 Prime95 is running 1T
C7 1T is ok @about 1700Mhz even with 1.55V
2000Mhz is good for little benchies with TRCD @10 but stability is far away even with 2T and 1.65V (but I am with 8GB)

According to RAM list they could be Powerchip or Hynix. What do you say?

[FlanK3r]

Chew* Can u comparsion your result with simillary CPU and NB clock with RAM about 1700-1800 MHz with tight timings? Im so curious, what will be better . Thx

For thuban its a waste of my time. I already know it's slower. With deneb however it will be close.

Point of a low clock challenge which that was for is to get under a range, sub 15 sub 16 etc etc with the least cpu core possible. Cpu core is the only factor that it's measured by.

My run was on water, why would I castrate my run to match what you can or can't do on equal terms.

[Punisher!]

I can't compete with hypers peraphs but it doesn't seem so bad to me, seeing also they are 8GB 1T:

Ooooh, I got burned. Hard.
*makes run to Taco Bell*, *takes out 2k loan to bin a few CPUs and get 4 sticks of GTX4* (just joking of course)

No seriously, I understand what the point in that run was...to get sub 15 at lowest CPU speed. I've seen it's your entry in the Low Clock Challenge thread

It seems I will need ~4450/3340 NB to get sub 15 on these Hypers, (I was looking at ~15 min 5-10 sec without maxmem at slightly lower clocks but run failed loop 15 )... I do not know how NB scaling works though.

[chew*]

Infra is running and can run higher NB than my chip so mine is nothing special. Secondly we told people how to attain higher NB, flankers post is an example and he did that on air, Infra and I are on water.

As far as binned ram thats laughable, its a single 2x2 gig set of flare that I got for a review. NB gains something but it's not a miracle worker.

Yes, my chip will not do 3100 on 6 cores, my 965 would on two cores I get 3300-3350 @ 1.425v like I said. I didn't claim your chip was something special, I'm just joking around because I suck at overclocking (and subsequently never come up with results, most likely due to myself trying to match results or get results my hardware is not capable of).

I was joking about binning about 6 CPU's and picking up a few sticks of GTX4, I would have said Flare or RipjawsX but Flare are gone and the only Ripjaws I will think of getting are the 2200/2133 C7.

Hmmm, tried to get a good score at ~4160MHz like has been used for reference but it wasn't as easy as i hoped it would be.

Tried to boot at 3375MHz cpu-nb (2cores) but it could not load windows, maybe 1.34V wasn't enough?

Furthermore, i don't think Windows 7 is that bad for running 32M, switching to XP didn't gain much, at least not as much as i hoped.

Here's the best i could do:



Pretty sure there's room for improvement, a set of Flares would help.

[FlanK3r]

Zeus: try more CPU/NB, think, fo benchmarking only is not dangerous. For 24/7 Im used max 1.3-1.32V, but I tried for this superpi 32M 1.4V and booted at 3400 MHz "easy"

[Daveburt714]

This has been fun (for me anyway )...
I really thought I was going to be able to get a sub 15m/32meg.

It still seems within reach, but I'm pushing V's alot higher than I feel comfortable with, and to be honest, I like my gear for now...
I don't want to break anything.

And yes Zeus, I used all my weak azz OS tweaking skills to get this.

So close, but no cigar...

[FlanK3r]

Dave, change your tRCD and have under 15 think.... (try 8-9-7 or 8-8-7)

[Zeus]

Nice try Dave but i think you'd better slot in your Corsairs and try to get DDR1750-1800 6-6-6-18, pretty sure it will be a lot better.

Have to agree with zues here, PSC shines if you can get 7-9-7 2000+ otherwise latency will still wins, maybe even 8-9-8 and high speed but it needs to be 2000+
