SR-2 Optimization Thread

Thanks for the info. I'm installing Ubuntu on Ext3 now. BTW, where is the UserId stored in Linux? I stopped the WU midway and switched OS and looking to resume after the new OS is up. Is copying the entire "fah folder" good enough? (In windows, I would need to import the registry key to set the UserId).

machinedependant.dat in the folder - you are good to go. (assuming permissions are ok)
 
Thanks Tobit. I resumed folding on the new OS on Ext3 now. Will know the result when the WU is done. Hopefully the delays are gone.

Anyone seen this weird delay time shutting down the core (delay 1) and getting new WU (delay 2). My sr2 is using Ubuntu with and w/o the Affinity Wrapper (same delays). When I tried it on FC 14, the delay is cut in half but still add up to 30 minutes worth of waste. During delay 1, the hard drive activity LED is on - it seems like it's accessing the disk. I have tried both the USB Flash drive and internal Sata II (several different drives), same delay time. Tried partition type: FAT32, Linux Ext4, XFS - non seems to solve this delay problem.

I tested copying the WU result file (about 100MB) on the SATA II drive and it took less than 1 second. Could it be the write delay cache setting? Doesn't make sense to me. Any idea?

The two number that point to the known filesystem issue are these:

[14:29:20] - Shutting down core

That is a 39 minute delay between when the results are written to the disk and the unit actually finishes. ext3 will definately fix this. The two number you highlighted are due mostly to upload time. I think that you will see a short time between these two with ext3:

but not these two:

Your upload time is actually really good. You must have pretty nice upload speed.
 
Thanks guys, the resumed WU is done now and confirmed it has fixed both delay 1 and delay 2. Just saved myself 36 seconds TPF which translate to about 50k ppd per box :D

Just ordered some myself. Should have them soon.

Nice, the dudes shipped pretty fast from HK. He shipped Monday morning and I had them here in the North East on Friday morning. My original SR-2 will be back here on Thursday, I will be rocking them then.

I paid for expedited shipping so I hope to have mine by Friday. Now I just need to figure out how to get my RAM to clock above 1600 on my SR-2.
 
Im having trouble getting my SR-2 stable at anything about 180bclk. If I go higher I start to get a jumpy mouse and the keyboard lights start to flicker. Both are USB hooked to the USB hub in one of my ZR24w monitors. Being that my board is was nitrobass24's at one point, I copied the setting on post 156 of this thread and started backing off BCLK. The problem persisted until I cleared CMOS. Can anyone point me in the right direction with fixing the USB?

TIA,
Max
 
L5640s. I tried both the 1.3875 vcore, 1.375 vtt, 1.4 & 1.425 vIOH and 1.3 vcore, 1.35 vtt, 1.4 vIOH. All boot into windows and have the problem with USB. The lower vcore finally BSOD after ~5 mins. I thought I read that IOH had to do with USB so that is why I tried to bump IOH up to 1.425v, but it made no change. Im running turbo with C states off and 1.65 v dimm 9-9-9-27 @ 1333. I am running the coolers pjk had on it, but am going to get the cpus under water this week or next if I can get an OC.

Thanks Max

does the A0 have turbo disabled?

Nope, turbo engages fine but they don't like a lot of BCLK. 173x20 is the best I've been able to do on them regardless of voltage and memory settings.

Have you connected power to the floppy connector "for USB and memory" on the motherboard? That might help.
 
The SR-2 is getting a much needed BIOS update soon. EVGA_JacobF has said that a new BIOS is now in testing and should fix the following:

* Enable/disable C1E support
* Ability to set fan type
* CPU Frequency reporting on post
* Ability to modify CPU shutdown temp
* All raid roms, microcode and firmware latest
 
Good to know, thanks Tobit. I've been out of the loop lately, but this is exciting. Can't wait to try it! :)
 
I also asked on other threads but really need some help:
I have E5506ES and X5570 and cant get either to boot my SR2. Get a error code 04 and booting stops at NVRAM Scan

do you have a Core i7 desktop CPU? IIRC you can boot with one of them in one of the sockets.
 
A little off-topic, but at Computex in Taipei, EVGA just confirmed an SR-2 replacement, a dual X79 board is in the works. Source1 and Source2.
 
Not off topic. This should be the only topic on the internet. We have to find another stockpile of spicy chips and we'll be good to go.

EDIT: :( that's almost certainly over six months away. We best put it out of our minds.

I'm hoping Asus drops their hat in the enthusiast 2p ring as well now that they have Peter Tan, would be nice to have some competition here...
 
DUAL X79!!!! OH BOY! OH BOY! OH BOY!
I was mighty hoping for some Sandy/IvyBridge fun in the 2P!

Can you feel it, Dual 8-core/16-thread Overclocked Sandy/Ivy Systems ^_^

Thats assuming ofc, Intel doesn't pull something like they did with the LGA1155 and lock everything to the BCLK, making it impossible to overclock with anything but a K series CPU.
 
If only there came an enthusiast dual C32 board for when valencia hits... That may be wishful thinking on my part. Enthusiast G34,2P G34, 4P G34???!!! Nah that is just insane to hope for that.
