SandyBridge 2D madness - let's tweak for the best 1m, 32m, pifast and wprime!

nice work chew

[quake6]

Chew, what bios are you on? And how did you manage to get hypers stable above 2133MHz??

[chew*]

My buddy Brian Y. told me that if i wanted to impress him to show him that kind of effeciency on ASUS so here goes.

I had trouble getting that last tick out of it, then again I fought with the Giga for that last 6 mhz as well.

Now that 6 mhz is worth 00.500 for me, so that leaves roughly .250 left difference.

Variation in bench or board?

You be the judge.

Enjoy.

[FlanK3r]

interesting...Its any logical result? Its diferent board to board etc (at AMD think is the best for superpi Cross IV Formula)?

[aristidis]

And one from me sub 6min. My cpu is maxed there.

Not to take anything away from anyone as results in this thread are all top notch but that is very nice especially with 8GB too.

Very nice!
Is that 4 2GB sticks or two 4GB ones?

its all dimms populated taking a second off the times

[aristidis]

They are 4x2GB and they are also different. 2x2gb GTX2 and 2X2gb GT CL8.

Nice.

@Brian
I need to borrow 2 GTX2 sticks from you.

For those of you that think the ASUS is slow and that's the only reason your effec isn't that great I highly suggest you go back and check your settings

can you post your settings please? Can´t run my Hypers on P8P67 EVO... Boot in OS is ok, but SPi gives freezes at all

Sure.....however I didn't use that board so I have no clue.

Red slots ( dimms 2+4 ), no more than 1.76 vdimm, I think Pll was 1.7? Bandwidth booster off ( useless for 32m ), Played with diff vcore levels and diff LLC configurations ( forget what I used ) which if you understand what this bench does and how it loads a cpu/memory can make a difference.

After that I followed this flowchart as far as timings go.

[Kurbel@HWL]

the subtimings would be interesting, the PSC sticks are running good on my Asus board, but Hyper...

If you can't run 32m without freezing with the above settings I suggested at default subs, my subs won't matter in your case.

I also think you missed the point of the flow chart.

[Bullet92]

I've played a little bit with 2500k and MIVE. The board is little bit tricky (all Asus?). Have to reboot 3+ times for getting the benches done with some freq..
chew, I'm looking for yours 32M and you're damn fast. Don't know is it because of the board or tweaking but I guess it's the first because my tweaking isn't that bad I think. Of course, I'm not expecting the same score with same cpu freq because I don't have Hypers but on 5520MHz I'm getting 6.03.xxxs.
I can do 7-9-7-24 too but have no time right now.. Next week I'm getting UD4 so I'll retest it and see is giga better or not...

[chew*]

Something sounds off if your doing 6.03 at 5520 and only 5:59 100 mhz higher.

Our scaling was preety linear with 2600K's, haven't had the luxury of finding faster 2500K's to compare though.

2600K
5520 = 5:58
5645 = 5:51
5746 = 5:46

Brian comparing his efficiency to us mortals again...

[3oh6]

i've got nothing on aristidis, his last loop>finish is a fat tenth faster than mine too, but here is my best from the UD7:



the sticks used are 2x2GB GTX2's and the old 2x2GB OCZ Blade's that i found in a box. the Blades still got it i guess.
i can also run higher memory clocks, but not high enough to get sub 6min with my efficiency...



efficiency falls off with the higher mem clocks because they aren't 100% stable, but more vDIMM doesn't help.

i'm curios to know what BIOS *chew is using on the M4E.

[chew*]

Usually if I don't comment it's because I can't unfortunately Jody, doesn't matter though.

I asked for some changes, thats the bios you will likely want, should open more doors.

[aristidis]

I have and a better one but my CPU just for 0.1 bclock up needed 1.65 vcore.

[SoF]

i've got nothing on aristidis, his last loop>finish is a fat tenth faster than mine too, but here is my best from the UD7:

last loop to finish highly depends on where your windows and Pi is located - Pi windows must always be on c: (!) and a rather small partition (<7-8GB, maybe smaller helps, hadn't the time to test until now)
can't remember if Pi had to be c: or different partition than windows - iirc for me c: windows and pi there also gave the best final loop.

(hope I understood your problem right - slow last loop?)

Waiting for a new C43 bios to continue 5 GHZ MSI challenge...with only 1.35V that isn't funny at all

[alex_tpc]

asus MivE B3 can run 4x2GB hypers at 2133 776. B3 came with 1103 bios and that works fine. Latest official 1204 bios a tad faster with CFG Lock disable in DRAM timings screen (which wasn't in 1103 that I could see).



Results seem comparable to UD7 adjusting for the UD7's 2Mhz extra (same XP SP3 OS, same subs):



Still can't get as efficient as cheapseats' 5Ghz 8GB results on the UD5 though.

[Splave]

w00t finally found an MIVE in stock good by deluxe, hello cas 7

[|ron]

This is our last run at 32M:


Tonight we'll try to go under 6mins!
We had no luck trying to use the 2400mhz ram setting...
Splave, did you try it or you're stuck with the 2133mhz setting just like us?

[Splave]

yep best I could get out of my gtx3's
