SR-2 Optimization Thread

I can tell you for the one of mine at 202 bclk, I have 6 x 1Gb modules. The other one at 198 bclk has 6 x 2Gb modules. 12 chips is probably going to hurt you, and the fact that they are 4Gb chips probably also hurts you. What is your memory ratio set to? What happens past 170 bclk?

A2 should be the same except the bundled testing card, or so I heard.
Anyway I'm ordering mine today. I'm still confused about the 2.0v ram I bought, if I should return it and get something else.
 
I need some help.

What memory timings should I use with my E5530 and OCZ Gold memory.

I either have bad settings or a bad stick. Running Memtest now.

Remind me to get my timings for you this weekend. I am at 8-8-8-20-2T, and I think I did actually set the other settings to 6-12-6-6 or something. I forget which is which, and the original SR-2 bios has them in a wierd order. I wanted to try to tweak them a little anyway, since SR-2 #2 is kicking this one's ass at the moment...

Note that this is the machine that did have two bad memory modules that I spent the better part of a weekend identifying.
 

Memory Installed: G.Skill F3-16000CL6T-6GBPID (2GBx3)
2 kits, 6 DIMMs, 12GB total

CPUs Installed: L5640 ES

BIOS Version: 49

BIOS Memory Voltage Setting: 1.65 V

Information as seen in Everest:
CPU Clock: 3600 MHz
CPU Multiplier: 18.0x
CPU FSB: 200 MHZ
Memory Clock 1000 MHz
Memory Speed: DDR3-2000
Memory Timings: 6-9-6-24 CR1
DRAM FSB Ratio: 5:1
 
See windows will get to the logon screen, I type in password and it will crash.

I tried to load the calculator and the system crashed. Othertimes it would be as simple as loading a youtube vid.

Funny..... I just swapped vid cards (8600gt for a 460) and I'm working now.

Does anyone else have problems with fluctuating multipliers on their ebay special L5640s? Above 195ish bclck, the multiplier fluctuates between 15x and 25x under heavy load, which eventually causes a the system to crash. I have turbo/speedstep on and cstates off. However, turning off turbo/speedstep does not stop the multiplier from changing.

I've tried CPU PLL up to 1.8v, but increasing the PLL voltage seems to, if anything, make the fluctuations worse.
My settings are:
CPU Vc: 1.2v
CPU Vtt: 1.3v
IOH: 1.4v
RAM: 1.65v
CPU PLL: 1.65v

I've tried bumping the Vcore as high as 1.35v, which does seem to reduce the severity of the multiplier changes, but not enough to stabilize the system. I've also tried Vtt as high as 1.4v, which did not appear to help at all.

This is my first day of overclocking with my SR-2 (2x L5640s) and I just watched my multi jump from 18x to 19x, and from 19x to 21x (resulting, for a moment, in a CPU-Z reading of 4.6GHz (!) ).

I'm just trying out some initial stress testing though, so I don't know what kind of effect these jumps will have. Currently testing 200 BCLK, but as I'm typing this I am watching my BCLK jump from 200 to 288 (for whatever reason) and back again, and my multi is anywhere between 15x and 24x...

Any thoughts? Still very new to this board.

Welcome - we love new SR2's here! :cool:

What you are seeing is turbo kicking in and off. CPU-Z does not handle it too well, and I think it might be a CPU-Z bug - I highly doubt you are really going to 288 bclck- download and try Argus Monitor and you can see a graph of you actual CPU speed as it is happening - it is flawless compared to CPU-Z.
 
Thanks for the tip! I'll install it once this run of LinX is completed (or if it fails ;) ).

I've been attempting to take in all the different opinions on settings around here and right now I'm trying 1.35 Vcore. Changing any values in the signal menu (the "-85" and "-15" stuff) resulted in the board failing to boot, but everything else has been POST-worthy, it seems.

OT: Any idea what max acceptable temps are for these chips? I've got mine stuffed into a Cosmos 1000 using H50 coolers (cable management can only be so good since there's no room behind the mobo tray)...reaching 60C while stress testing.

Those temps are more than fine.

I run aircooled and am happy with 60's to low 70's - once things run over 80 I take action. 95 is the absolute redline.

CPU-0 will usually run way hotter than CPU-1 - don't worry about it. It is an SR2 thing!
 
nice work jamming the board into the cosmos

now you just need to join the right folding team :)
 
Why are yalls temps so high?
Running my L5640's @200Blck i stay right around 50c
TRUE Rev. C
 
TRUE spirits here, 196 Bclk, 1.35 vcore, 1.4 IOH
max temp averages to 56 something

Why are yalls GHz so low? :p

x5660s and 50s can go a lot higher... if you keep adding vcore. The price is temps.

Mine have to be dealing with 200 watts+ each :eek:
 
If it doesnt work in the SR-2 it wouldnt be a chipset limitation but a BIOS limitation.

SR2 might be one system where pushing the vcore 0.1V higher for a few hundred extra mhz might make sense with the non linear bonuses. Even if it takes 100W extra you can get 15k ppd more on average.

You nailed my strategy in one! :cool:

Which is bit better than you would get by adding a GTX-460. But as I am finding out, my strategy has weak points:

  • Perpetual shortage of bigadv
  • which means SMP units
  • which means frequent low points 6701 and 6702
  • which also means frequent 503 error outages waiting for the 6701/6702 server to accept finished work.
Hence running at about half of max capacity.

It is like a Ferrari getting off a log jammed freeway only to get stuck bumper to bumper in a worse jam on a secondary road. :(
 
good news, lolfolder is back up to its asymmetric full capacity :)

Ever since I tried the NUMA trick, it wouldn't POST with my hex/quad combo. So, last night, in a last-ditch attempt to get my PPD back up to a respectable level before I head out of town for a few days, I updated the BIOS to Loco Laptop's A49, and also, (I think this might be the key) I plugged in all the 6 pin optional power connectors. So far, so good. Back up to 190x20 = 3.8ghz, NUMA enabled :(, running SMP -18

I haven't totally given up on NUMA yet. I haven't tried to disable NUMA with the PCIe power connectors in place. I really wonder if those connectors are the key to achieving better than 190 ish BCLK.

Does everybody who is beyond 190ish BCLK have the optional power connectors plugged in?

I plugged mine in right away (8pin + 6pin) and I was pretty surprised at how the board just fired up with 200 BLCK without issue.

I'm trying out a single SMP WU this morning to see how things go. The client downloaded a 6041 project and my average TPF is about 3:45 at 3.6GHz (-smp 24). Googling around, I see that 6041 is one of those slower WUs out there? I was kinda hoping to get a 6052 or something that I could compare with since I folded at stock settings for a day (where the TPF was 1:40 at stock settings).
 
that's about 64,000 ppd. sounds about right to me

I have all but one 8 pin connector engaged on mine. I need to find me a molex -> 8 pin power adapter or something so I can plug in that other point. Using a Corsair 750TX with mine, and it's pulling about 510 watts total.

2x L5640 Extra Spicey CPU's 3.6 Ghz @ 200x17 (18) with Turbo engaged.

Are you running 5650's to get a multi of 20?
 
you're missing an 8-pin?!?

I have a frankenbox with an X5650 hex core along with a E5640 quad core, hence the "lolfolder" name :)

Both with 20x multi

Because our multis only go up to 18 w/Turbo. (us L5640 owners at least) :eek:

And extra juice. What's the Intel spec, I believe it's 1.35 max Vcc and Vtt?
Again, L5640 I'm running 1.2 Vcc and 1.3 Vtt. Vtt was the key, but I've hit the bclk wall on these puppies (most other L5640 owners are the same way....get 200, anything above is luck, and usually only a couple more ie 203 was my max).

Let's see...12 slots times 16gb DIMMs equals 192 gigs of RAM, minus one mortgage equals sleeping in the dog house times no food...:p
 
192 Gigs of Ram.. my HDD on my SR2 isnt even that big lol, hell it's not even half of that lol

And how the hell are you not using an 8 pin??

If anyone read the picture (poster actually) that came with the SR2 it says right on there to use the extra 6 pin for each CPU to help with OCing, and to use the floppy pin as well (EVGA forums confirms this helps with USB drop outs at high OC's)

It says if you want to OC why wouldnt you fill all the power plugs? I still don't get why people wouldnt use them from the word go. Most of us are pure SMP guys, so having 2 6 pin connectors is no biggie on any PSU we would use, and just use a dual molex to 8 pin for the other CPU

I mean all you need is

1x 8 Pin
2x 4 Pin (+8 Pin Adap)
2x 6 Pin
1x Floppy (same line as dual 4 pins usually)
1x SATA for the HDD

It's not like every PSU that is over 650 watts doesnt have those pretty much, why wouldnt you use everything? The poster (and EVGA) confirm the only one that should be optional is the 6 pin for running Quad SLI...

Great job jamming it into the cosmos 1000. I have the same case that house a x8dah+f but plan on ordering the sr2 soon. How many of the stand off holes lined up for you?
