our plans are to purchase Sr-X, but before we do, can TWO Xeon E2690 processors be overclocked on the SR-X?  The RAM we'll go with is a Gskill F3-2133C9Q-32GZH, 96GB in total.  were not seeing too many compatible ram's for Sr-X in 96GB range.
 
thanks for your input.
 
 

yes were definetly going with E2690. Would Crucial RAM work, model# BLS4K8G3D1609ES2LX0  or BLT4K8G3D1608ET3LX0 ?  
 
Lastly which setup would be faster in this case?  
 
Sr-2 with two X5675 overclocked to 4GHz with 48GB of RAM   OR  SR-X two E2690 running stock speed with 96GB of RAM ?
 
thanks in advance.
 
 

The SR-X only officially supports up to 96GB as seen here: http://www.evga.com/products/pdf/270-SE-W888.pdf. If people are trying to reach that amount of memory it will be at there discretion.

Where can I find 192GB of RAM?  most are 32GB kits for SR-x.  also specs on SR-X say 96GB is that misleading?

Since I'm going with two E2690 Xeon and I can't overclock it, are there any special settings I need to put in BIOS(voltage etc) or is it just auto.
 
Also I noticed that the Xeon E2690 CPU have a turbo mode to 3.8GHz, is there a way to force it to stay on that mode ?

Updated to the latest BIOS version.  I'm now trying to set my RAM and Voltage to the following:   8-8-8-24 / 12800 and voltage 1.35v  96GB  total.  can someone kindly share with me what these are referred to in BIOS for SR-X? 

okay I'm there now, but for some reason it still shows DIMM in whole numbers like 1530 etc.  how do I get it to 1.35V  per my RAM requirements ?   also for RAM settings 8-8-8-24....what are the  names for these i.e. is it TRC, TRAP etc?

Okay so I went into BIOS, Applied 1350 for voltage 8-8-8-24.  I set memory speed to 1600.  All I get is a BLACK screen, no post and no classified splash screen.  I do have 96GB here, I'm not sure if I need more voltage?  Crucial ram says 1.35v on the ram sticker.

Crucial Memory Model# BLT4K8G3D1608ET3LX0  32GB Kits x 3 qty.
 
I went under Memory performance, it says Automatic, Manual, xmp profile 1 and XMP Profile 2.  I set this to Manual which gains me access into the memory speed settings page.  I then set the memory Speed to 8-8-8-24 and 1600Mhz.  I SAVE and Exit...everything is fine ...I then go back into BIOS to set the voltage.
 
The Voltage I'm setting is called CPU 0 DIMM Voltage Control, I set that to Manual mode and it says "currently" 1.405v , I type in 1350.  I go under CPU 1 DIMM Voltage Control, Set that to manual, I type in 1350.  I then SAVE and EXIT.  After it reboots, I get no Post, no splash screen, and the DIAG code sits on 67.  I have to press the little RED reset button to get things back to stock and for POST to show up.
 
Also I'm using TWO Xeon 2690 CPU's in my setup, I don't know if that makes a difference?
 
thanks for your help.

I set the memory to 8-8-8-24, 1600.  I left voltage on Auto which shows 1405 .   I will load OS win 7 x64.   I do know that it loads from cd just fine.  in fact I was planning on using Memtestx86 and run that for 48hrs to make sure my RAM was fine.

With just the DVD/CD Drive connected to the Port 3 sata, I inserted my windows 7 X64 DVD, it shows the bootup splash screen and than moments later I get the famous blue screen with the following STOP Codes: 0x0000001E, upon reset I get 0x0000007F, and than the last one as 0x0000007E.
 
Not sure what to make of this. 

The reason you were only able to achieve a frequency of 1600 is because it is limited to the memory controller on your CPUs. This can be seen here: http://ark.intel.com/prod...-GTs-Intel-QPI?q=2687. The CPUs are locked units by Intel and you can't do any type of over clocking including the memory controller. You should be able to get any timings recommended by the memory manufacture as well as voltage settings. Thank you for the update regarding the latest RSTe I will definitely forward this information on.

I have GSkill 2400 ram, and after multiple attempts the best
setting I could get stable is 10-10-10-28 at 1600.

I have 2 2687w's, and 96gb as well...

Also btw, if you want decent performance with the SAS controller
it is imperative that you install the latest Intel RSTe 
drivers, ver. 3.5.1.1009.

Admins, please post the latest drivers for the SR-X on
your download site! The Atheros AR3011 bluetooth driver is 
actually from 2010 for example!

I don't see how hard it would be to have all of the
latest drivers available...

Not a problem and yes I will talk a look into any other driver/updates for the SR-X.

Thank you for your reply JoeyC.

I understand that fully after being made aware of that a while
ago.  I was trying to help johnkingx with his dilemma with
setting the speed and freq for his ram.

Also could you look into what the latest drivers for 
the Marvell eSATA controllers and Atheros bluetooth are?

Thanks again...

okay we got good results with ram settings to 9-9-9-24 @ 1600 with AUTO Voltage.  I'm currently installing Windows 7 X64 across 4 Samsung 840 512GB SSD.  its looking alive so far. 
 
No matter what voltage I set the DIMM to it won't post, very strange.  Auto voltage seems to work fine however.

johnkingx try 10-10-10-28 at 1600...
