Here for the SR-2 users a new bios version with the C1E option added,

and some better Bclock OC.

 

C1E option is under Cpu settings.

 

Flash methode included for windows 32b/64b and DOS.

 

Have fun with it.

 

When encounter faults, problems or any other not normal thing, just let me know, i pas it on

HIHI

 

Who modified this bios ?

 

 

For flashing, change name bios 1W555A53.rom to 1W555A50.rom

Only C1E? LOL

 

There's a bunch of locked stuff left - QPI slow mode, Memory controller mode (Xeon/NUMA stuff), peripheral stuff - PCI-E ports Priority, Enable/Disable and APIC. Some other stuff like "Hit del message display" and "Wait for "F1" if Error".

 

Might be even more, didn't look deeper.

 

Well, the memory mode is more like RAM RAID. While NUMA has a different menu hidden a bit deeper.

+1

 

and:

 

real GHz cpu in post screen, in defaut change ordering check PCIE ....

i sended it to Evga this question :

 

 

High Prio :

 

QPI slow mode,

Memory controller mode (NUMA options),

Peripheral stuff - PCI-E ports Priority,

Enable/Disable APIC,

Possible to disable NUMA with dual GPU vga in the system,

Possibility to run a out-of-shop raid ssd PciE (look at revodrive's).

 

Low prio :

 

"Hit del message display" and "Wait for "F1" if Error".

Possible to disable NUMA with dual GPU vga in the system

 

Its phisicaly possible ?

normally yes,

NUMA option is about sharing the mem for both cpu, or dedicated mem for each cpu.

 

stranbge that numa disabling doesn't work with a dual gpu vga in mobo

possible its due to low gap memory can t alocate RAM per GPU when NUMA disable.

Low gap option is also in bios, but doesn't help in any way you set it

Update :

 

Seems that USB3 problems (BSOD) is of the track, used all night usb3 in all kind of situations and don't get any BSOD anymore, hope other users can confirm that ?

I have already see a bsod due to the USB 3 but its hard for generate this bug.

 

I remember a problem which would be interested to correct:

 

The OC BLK by 2 steps

 

If you try directly more 155 BLK, after shut down the motherboard make FF.

Chiller, I've just listed what the features are there but are disabled. I can unlock them by my own, it'll take only one cup of coffee

 

If you contact with EVGA better ask about 8GB and more of memory per channel. As I've heard neither a single 8GB module nor 2*4GB on same channel work after reboot (they boot but after saving CMOS the system doesn't start). And some want even more memory, say 8GB modules in all slots.

i had the 4x 4Gb and 6x 4Gb in my rig and worked just fine.

but because of timings i did go back now to 6x 2Gb, sharper timings.

 

I think is more user defined with settings you use in bios...

I am running sometimes with 8GB modules (Hynix HMT31GR7BFR4C-H9). At the moment board with one X5690. Managed to post with very weird settings. No post with setting mem in bios 800/1066 only 1333 and needed to rise IOH to 1,425V. Booted @133 with one module and fixed mem timings. Then 3 modules bclck up and 6 modules. Important to set manual as much in bios concerning mem settings/timings as possible. When settings and timings right not much difference 3 or 6 modules. Sometimes after cold boot or after BSOD unable to post, need to start from beginning. Got board running stable for 2 weeks. Now again no matter I try need to run @175, was able to run tests these 2 weeks @181/182. I am bit afraid about memory, but not have found way to run it at lower speed 800/1066. Just not able to post. Hope new bios solve memory bug and can my 48 GB within specifications

did you try it with NUMA option changed?

 

it's under power management options in bios.

With/without NUMA in every possible combination I could think of I have X5677, with this cpu it was the same. Yes I know. It is starange, somewhere I read all dimms populated memory should run only 800. Maybe bios display something wrong but all other information tools confirm it.

I ahve me too a strange RAM bug.

 

Once we set BCLK higher than 193 MHz, 24GB of RAM are ramdomly detected.

whatever the setup (CPU voltage, timings or other) no way to solve it.

The higher the Bclk is, the lower the detected RAM quantity is. @ 23*196=> same issue.

It's not due to the high frequency of the CPU.

 

 

And I whant stay at 196*25

 

I encounter this problem with 12X2GB 2000 C9 kingston HyperX and 12X 2000 C6 gskill.

 

Disabling NUMA not corect IT

 

Whene I have 196 blk tedetection ram its min dectect 4GB at 16GB max NEVER 20 or 24 GB.

and at 203 BLK its lower GB detection.

I have tested in SR 2 friend setup with 198 BLK with 24 GB GSKILL and no problem. all RAM is detected.

I hope this problem its not due to BAD IMC CPU due to ES verssion.

 

Have you ever encountered same problem ?

when you supply ALL slots of mem, you're mem will be downclocked.

 

therefore it's best you only populate 6slots if you whant to run it high.

 

Has to do with limitation of IMC

I am running board now with only 1 cpu, 6 slots (all for this cpu) filled. Do you mean if I could use both cpu-s and fill 12 slots then mem will be downclocked?

Right now E-leet; CPU-Z and Aida64 tell me I am running 6x8GB 2:10. As far I am aware :

800 = 2:6

1066 = 2:8

1333 = 2:10

Correct me if I am wrong.

not bad bandwidth.

 

Certenely worck, use just 6 slot in same CPU but with two CPU active.

will not work mosie, you need with 2 cpu's in mobo also with each cpu to put mem in.

 

will not work when you have 2 cpu's and only on side of 1 cpu mem modules.

 

When i mean 6mem modules, i mean in the red slots with each cpu in bank 1, 3 and 5.

 

As for the downclocking, i mean when you are running two cpu's, and put ALL mem banks full (all 12 slots), the IMC is limiting factor.

don't think with 48gb of ram you will be able of running it at 2000Mhz if you have corsair dominator GT 2000Mhz.

"will not work when you have 2 cpu's and only on side of 1 cpu mem modules."

 

Its worck, I have test this.

1 module or 2 or 3 or 6 put in one CPU with no module put in second CPU: WORK. NUMA mod men ....

 

 

 

I would need the help of the users who have any CPU CPU 6.40 GT/s to have 2:10 ratio, and 12X2GB.

 

If you can test run at more 195 BLK at 2:10 with any CPU ratio.

 

The purpose is to see if all 24GB is detected when MHz ram is more than 950MHz.

 

It might be possible that nobody is able to succeed with 24GB at this MHz.

lots of mem on Sr-2 is known that you're mem will be downclocked.

 

told you allready before.

 

Limitation of IMC
