Hello,
We have another forum user who has said he managed to get the W3690 working with the westmere mod on the X58 linked here http://forums.evga.com/X58-SLI-MB-and-Xeon-W3690-m2367243.aspx
Our official information regarding CPU's that have been verified working are listed here, though we do not have this exact CPU listed: http://www.evga.com/support/motherboard/legacy/  
Please let us know if you need any additional information regarding this.

Hello ljport78,
Thank you for sharing that information and good to hear the mod worked for you.  I personally have not done the mod on mine yet though I am considering this since the 990x is just still too expensive, not worth it in my option.

ljport78,
I was using the 920 (never tried to OC) with a GTX 960ssc. I went to a 975x which I Oc'd to 4.1~ noticed quite a bit of improvement then decided to go to a GTX 1070 and its running pretty good, Firestrike score: http://www.3dmark.com/fs/10830851 .  I agree this board still has some life left in it so might just try to get a westmere or just keep this as is until a new system build.

Hello bill1024,
Great information!^ Thank you for this.

I have seen the W3680 for under 100$ and x5675 under 70$
The W3680 and 90 are multiplier and BCLK unlocked. The W3670 has a locked multiplier, unlocked BCLK
The x5660 with give you 23 x and the w5675 will be 25 x multiplier.  Multiplier is locked on L, E and X series xeons.
I have had better luck with odd multipliers. My single socket 1366 are all x5660 and I run them 175 x 23  for 4ghz every day crunching.
Try to keep the CPU to 1.35v or less and the VVT / uncore to 1.35v or less on the X, E and l series. The W series can take a little more CPUv.
Also I have found that the xeons like the uncore speed to be 2 x ram speed or one click under 2x ram. They say can be 1.5x but that never worked for me and you will get much better performance at 2x.
 
Ram speed is limited to 10x I do believe, so lower timings is something to shoot for.
200 buss speed will be 1600 @ 8x. Some of mine run 14xx 7-8-7-24 1T  So depending on your ram.... YMMV
Hope this helps some.

O wow, nice gratz on the Blue Ribbon^.  All this talk convinced me to finally Westmere Mod my X58.  I will be definitely trying either the W3690 or the X5690 shortly.
 

actually looking at grabbing a w3690 off ebay for $130 but not sure if the x58 760 boards require the mod. anyone know if it does?

Hello quadlatte,
If you see rev 1.1 printed on the edge of the board then no modification would be needed. Though if you are not the original owner it is possible the westmere mod could of been performed on the board. If you are uncertain then we can confirm by some pics which you can post here or even email us at support@evga.com .  Please let us know if you need help.
 

thanks. but yep its a 1.0 board, i did buy it from the marketplace but i dont think the mod was ever done. what and where is this mod that needs done, i realize its my own risk but its a play thing and not my main or even secondary pc at this point but wouldnt mind using xeon 6core in it.

Since mine is a 760 the layout does not look like the one in the link. I do see the listed numbers printed below and to the right of the cpu socket with alot of other numbers, it looks as it may be under the large heatsink for the x58 chip. Can you confirm the location for 760

I will forward this to our Product management for review,  stay tuned.

I agree^ I am curious also and I am sure many here would really enjoy the information to be confirmed

Hello quadlatte,
 
That is great to hear, thank you for confirming that^.  I did get word back about these inquiries though unfortunately we are not able to provide official steps on how to perform the modification. Though If anyone ever needs to confirm if the mod was done you could send us a pic to be reviewed.

quadlatte,
Good info,  thanks for sharing^

Just put a w3680 in a SLI3. Runs @ 45-47C @3.9GHZ  while gaming with air cooling. (EVGA superclocked cooler)This is temperature precision is reporting in the OSD. Passmark scores it higher than 980x or xeon x5680 in benchmarks at same frequency. What a deal for $80.00.

Definitely, running mine at a mild 3.6 with default auto volts, plan on trying for a nice 4ghz everyday oc. I only wish my board supported faster HD speeds but looking into changing that with a pcie add in card soon.
