You probably need different memory settings or something...reset everything to auto and start sneaking up on it.
 
Damn it, don't have time for that lol, I'll play with it next week after 4bil

to he'll with it, vcore 1.35, vtt 1.35, ioh 1.375, everything auto, ram divider is the middle speed
I'll see what that gets me, sky nets only been doing 30k for 2 days so anything is better than just waiting I guess

Middle speed =1066 right?

Yes, I'm at 170 now, 3.06 ghz, checking TPFs on my first unit a 6050
Posted via [H] Mobile Device
 
170 = 3.06 = 1:23 TPFs on a 6050 = 57k ppd

trying Numa thing now, that's as far as she goes tonight, I've worked 10 hours, done a PT test, and work again at midnight, no time to dick around with OC'ing till after 4 Bil, which is what, 1.1 days away lol

Sorry for the tripple but I'm too tired and can't get my phone to hit the tiny tiny edit button

Numa on @ 3.06ghz , 1:23 TPF, 57,000 ppd
Numa off @ 3.06ghz , 1:18 TPF, 60,500 ppd

that's 12k better than skynet2 got on dual quads at 3.95 ghz, and temps are in the mid-high 40's

can't wait to play around more but I need SLEEP!!

I'm really happy it increased your productivity too. Nothing like getting a boost in folding and rendering.

How's about AN and BN > Before NUMA/After NUMA :)

I really hope you got some sleep MIBW. You are truly a [H]ardTr00per

I'm going to stop tweaking for the time being and just let'er run. 16:25 TPF on a P2684 is good enough for me. 27.3 hours is good enough for now to keep the "D" up.

I am hoping to get a P2685/2692 and watch the wings sprout.

BTW thanks for that upload ;)

EDIT: I'm seeing an 8K PPD upgrade on a P6061. My original numbers were 72,000 PPD on it, and now 80,000 since UMA came into my life. TPF only went down by 10 seconds, but a big difference even on regular A3 SMP.

Yup, this NUMA thing has done everything for me but wash my car and stop me going bald.

Great suggestion on the sleep - my body made the same offer I couldn't refuse about 8pm last night.

Is it being greedy to dream about getting one machine on a 2686 and the other on a 2692 tomorrow, to get to 4 billion?

And my A3 SMP results are getting the same boost as you. (and I had plenty of units to watch that happen grrr)

I just got 12 hours awesome sleep - I just collapsed last night. Been some intense month of getting one SR2 working, then build another, while working.

Now it is pretty surreal - both SR2's crunching bigadv... can't stop to fiddle or benchmark... WTF do I do now? Just kick back, and watch HFM? My work here is done! :cool:

@musky - we always listen you you mate ;)

I am drooling just seeing you drool about one. But then I am not sure I am entirely normal.

Well, get the popcorn, and spend the whole day just looking at it tick over.
 
Getting 69k now, still regular smp's @ 180/3.24

loving these dual hex's! Once I awake from my coma caused by the last 30 hours I will tweak to 200 if I can. I can smell 100k in a box...

Skynet2 only got 75k on bigadv at 3.95 (max stable OC), I'm getting 69k on regulars now at 3.24, and pulling much less power and temps top at 51 :)

If I disable NUMA, I lose 1/3 of my ram (from 12gb to 8gb). If it actually boots. (like jebo)
Ram is stable otherwise.
Don't know if it's because I'm running previous bios (A47) or if it's because my ram is already oc'd (1333@1600) and therefore "fragile"? :confused: Works fine with NUMA enabled. Passes LinX, memtest etc.
 
Hmm, thats odd. I'll have to check mine again to make sure I'm reporting all ram. Tomorrow I'm gonna try and inch my way to 200, I think its at 185 right now
 
I have one with the A47 bios and one with the original (A41?) bios. With good memory, they both see a gain with NUMA disabled. With questionable memory that still passed LinX max memory, disabling NUMA caused serious performance degradation. With this questionable memory, it was always hit-and-miss as to whether the machine would read 12Gb, 10Gb, or 8Gb on boot. Since NUMA affects how your processors and memory interact, I strongly suspect you have a memory issue.

Yup, I spent weeks fighting this on my first SR2 build. If you are pushing the memory too hard (in my case 12 dimms) it will inconsistently boot up with less reported. It might be stable, but as you have dropped a stick or two performance goes to hell.

Loosening timings works to fix it permanently. Sounds like the NUMA made an existing problem worse. But very much worth running NUMA disabled, so I advise going looser. For me it was going from default:
7 8 7 20 9 64 5 5 5 24 1T auto(0) 64 65 66
to
8 9 8 24 10 67 5 5 5 24 1T auto(0) 73 74 75

Anyway, YMMV.
 
In my case I'm running 6 sticks of 2gb each Corsair 1333. They are 9-9-9-24, 1.5vdimm sticks.
I run them at 1600, 9-9-9-24, 1T, 1.65vdimm. I've previously ran at 9-9-9-27 (24 still doesn't make sense to me but that's what they run at stock). I've tried bumping vdimm. I thought I had a bad ram slot or two (which could honestly still be the issue). I dunno. I've ran these dimms for at least 9mos now, in now the SR-2 and previously my UD3R (on the UD3R I ran them at 2T). My personal opinion on 1333 is that it runs 1600 no problem, and 1600 is probably nothing more than 1333 with a higher voltage spec (I doubt there's much different in the IC's themselves between the speeds). Who knows though. :confused:
 
I have those sams sticks except the 1gig version. in a msi p55-gd65 also have run them @1600 same timmings as yours. but thats oh soo close to there edge. as finicky as those SR's seem to be probably beyond
 
I wouldnt say finnicky per say, more that there is a massive amount going on with the SR2 and it's got less room for error
 
what's the max safe voltage for ram? Is it the same as x58 (.5v more than vtt is fine)? I realized the dual channel kits I bought are rated at 2.0v... I would crank up the voltage to 1.9vdimm if possible.
 
I don't know, but be aware the sr2 reports v a few points higher than set. (1.65 = 1.68 etc)I haven't checked with a multimeter or anything, but if true you might exercise caution.

those sticks are not meant for p55 x58 boards. running memory voltage that high could kill the memory controller

I have checked with a DMM, and the voltage is about .03 higher than set in BIOS which I why I run a bit lower. A few hundredths either way probably aren't a big deal, but I wouldn't go much higher than 1.65V (or the max specified by your RAM, whichever is lower).
 
So is UMA a setting in the A49 bios? I don't have that in A47, just NUMA with the options of enable, disable, and enabled for something-something-something.

Just wondering if I should upgrade the bios or not; didn't know if it would make a difference (if you guys were disabling NUMA in A49 specifically). 10e mentioned enabling UMA, I didn't know if there's a specific setting to do so, or if the act of disabling NUMA automatically enabled UMA by nature.

Yeah, I could not see anything for enabling UMA - just disabling NUMA gave me the boost.
 
Yeah it must be my ram is just at it's peak.....if I disable NUMA, it drops to either 10 or 8gb.
When I re-enable NUMA, it's 12gb again. Oh well....

Did you drop the timings? Try 2T Command rate? Drop MCH strap one notch? Any timings loss will be more than made back by the super-dupa-numa boost I suspect.

It is the must-have accessory this folding season. :p
 
-Shouldn't need 2T though. 2T is generally only used if all ram banks are populated and in this case, they're not. I'm only running 3 sticks per cpu.
-Timings are already as loose as they'll get. 9-9-9-24, I tried 9-9-9-27 just to check and it still didn't work.
-Only thing that I wonder about is your mention of MCH strap, I believe I left that on auto. Ram is running at 2:8 (1066).

Not sure what you mean about 9 9 9 24 being as loose as they get - it this timings set manually? do they not boot at super loose 11-11-11-24?

I am running 9-10-9-24 on mine - as I am running at 1850DDR - 2:10 @ 185 bclck.

I was only suggesting 2T as a proof of concept - just to see if you can boot with all ram with NUMA disabled.

What is you bclck? Try MCH of 1600.
 
NUMA diabled results on a dual L5640 @ 3564 machine - memory 1584 MHz 8-8-8-20-2T

P2692 - 13:15/frame, 127K ppd

Wish my other SR-2 would get one since it is a bit faster. It has run 16 regular smp units... :/

On a side note to Numa - does it have any affect on the Asus dually boards? - i'm hoping to get mine up and running in the next few weeks and any tips will be great

Yes i dropped about 2min TPF on my ASUS Z8NA-D6C

Yes, it definately does. Tobit is running that board now and it does much better with NUMA off. Any modern dual proc board should have a similar result.
 
127k ppd... Hope I can get mine up to that, havn't been able to grab a bigadv unit yet

I'll post my settings later tonight hopefully but It seems I may have been using too much voltage earlier, it's odd, I was running specs copied from this thread, but at a full .03 volts lower I'm stable (3 days now) at 190 bclk

anyone get to 210 on these 5640's?

200. Tried changing the MCH strap, tried putting timings on auto (which boots at 11-11-11-29). For the most part, then I couldn't get a boot at all.

I may try to get 1600 ram down the road but right now I'll make due with what I have.

musky said:

Same here. Could not get above 203bclk on these L5640's.
 
MIBW: Did you ever get a decent overclock working when running 12 sticks of memory? Looking for ways to get to 24GB without spending a premium on 6x4GB DDR3-1600 sticks or going the cheap hex route and buying 6x4GB DDR3-1333.
