Are you by any chance able to explain the signal tweaks CPU0 IOH, CPU1 IOH and CPU0 CPU1, CPU1 CPU0.
 
Don't these values become rather important when hitting high base clocks?
I've tried screwing them around a little bit, but doesnt seem to help much, though they would seem valuable.

it's impossible to go over 200blck with this mdb???!? i have to stop there, 202 or 203 are possible, but stable on only one lynx cicle ;(

Excellent suggestion. Highly recommended. I have a 0.05v difference between my CPUs, which is quite significant. 
 
One way to test this without actually disabling the CPU would be to run prime (or your stability test program of choice) and set the cores affinity to the threads of 1 CPU (this would be 12 if you have hyperthreading on). That way you are only loading 1 processor during testing. 

hi guys,
 
does anyone have Shimano's templates available that they could either upload here or provide a link for please
 
thanks
 
Henrik

I´ve saved them as .htm. Anyone know how to upload in this forum, if possible?
 
Edit: Seems there isn´t such an option... I´ll try it on an one-click-hoster with long free-retention time.
 

I need the advice of the great Shamino  THANKS!

4000-4900mhz depending of cooling, cpu and memory.
Can upload it if u want.
 

Probably the memory is bad quality.
I overclock samsungs ECC 1333 1.5v to 1800mhz 1.52v  48-96GB with no problem.
I have 88-92mhz PCIe bus to get a lot of GPUS working and all netports and numa support ON, but it is best off with NUMA and one TP off.
U can probably run 4400-4500mhz 1.35-1.37volt with good watercooling and Bios setup correct and with 100 mhz pcie.
If your 1333 memory cant handle the OCspeed use the 1066mhz instead of 1333mhz and all settings same,,use 10-10-10-24 and 160 instead of 180 tRFC in MEM timings
 
Here is my setup:
 
 
  

 

Thank you for the screenshots! will try these settings then i get a chance.
Did you make changes to the signal tweaks?

4750mhz and 4810mhz, little more volt.
 

I finally figured out why my SR-2 would not boot with anything higher than 160 bclk.
I had a move the JIOH jumper from the upper position to the lower position.
@Robbanswe In what positions are your x-cool, i-limit, and jioh jumpers? There is no documentation on these 3 jumpers. I bought my sr-2 used on ebay so I have no idea what the default positions are

Ok.
JIOH and I - LIMIT is set to the Right.
on pin 2-3.
this is the original settings.
and it is highlighted to the right on mobo as well.
and a internet picture of x-cool original setting.

Samsung ddr3 ECC 1333mhz is outstandig for stable overclocking

192GB

My best working OC so far
4861mhz

Hey Robbanswe I'm using your settings on my x5675s and trying to get 4.5 on both CPUs. I'm running 180 bclk with turbo on to get a 25x multiplier. HWiNFO64, CPU-Z, and EVGA E-LEET all report 25x180 for 4501mhz on CPU 0, but reports 23x180 for 4141mhz on CPU 1. CPUID HWMonitor is showing weird 2161mhz on CPU 0, but it's also showing 4141mhz for CPU 1. Not sure what is going on here but wanted to get your input. I'll try with Turbo off but then I have to run 196 bclk and I'm not sure it will run that.
