Hello all, I am getting ready to build my SR-2 rig, full ordering will start after taxes, and when the GTX 590 comes out. Anyway, do you guys think I will be able to get to a 4.0 ghz overclock. I think I need a 223 BCLK (18x multi). First time OCer here, can i do it.. on air?
 
Edit: wrong multi listed when first posted

    Well it may be harder but 4.0Ghz is the top of what these processors can handle with the limited (x19) multiplier. The E5645 is essentially the same cpu I have with 2 added cores onto it, I can imagine anywhere from 3.6GHZ+ will be easily reached with this processor on air (I'm using air on my current cpu overclock). Using a Prolimatech Megahalem with 2 fans on it.

    I will either find a way, or make one.

    I have L5640 which is very similar but with a x17 mult instead of 18, I have them @3.4Ghz (when turbo) so at minimum you should get that :)

    No it's still a x19 multiplier sadly, macthes the same specs as my cpu but it has 2 more cores onto it.  http://ark.intel.com/Product.aspx?id=47925 18 without HyperThreading, 19 with. 

    I will either find a way, or make one.

    I'd aim your sights substantially lower than that. Most of the time going over ~195-200 bclk requires substantially more Vtt. You may luck would w/ your CPUs and be able to pull 205blck but I wouldn't give your hopes up. My E5645's top out @ 195bclk w/ 1.35Vtt, which gives 3.7GHz.

    EVGA SR-2 * (2) E5649 @ 4.1GHz * 6GB DDR3 * 8800GTS * 1050W Revo85+
    EVGA SR-2 * (2) E5645 @ 3.7GHz * 6GB DDR3 * GT210 * 1000W Antec

    Hi Lowfat, I had a question, but before the question, I wanted to let you know that I LOVE your system that you set up and am wanting to build one too that is as compact as that. Again, NICE, TIGHT, BUILD !!!  
      
    But my main question is about the E5645 vs E5649. When it comes to water cooling and clocking what realistic performance gain will I be able to acquire that much more with the 5649 over the 5645. I see that you were able to get 3.7GHz (E5645), and 4.1GHz (E5649). What kind of real gain is that in processing power; 10%, 20% gain in rendering power for high end apps like Final Cut Pro, Photoshop, Apple Motion, etc? Let me know what you can (or anyone else for that matter that may be able to help). Thanks. I also, PM'd you as well...
     
    Look forward to hearing back from you shortly. Later... PNugg... :-)

    Is there anyone else that has the Xeon E5645 Core Processors? Wanting to find out failures and successes on this chip. Whatever anyone can share would be great. Thanks... :-) Also, what would be the best RAM to purchase if I am to crank this chip from 2.4GHz to 3.4 or 3.6GHz? Is 48GB DDR3 12800 1600MHz RAM good enough?
     
    Like these G.Skills:
    G.SKILL Ripjaws Series 24GB (6 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9T2-24GBRL
     
    or this CORSAIR RAM: 
    CORSAIR Vengeance 24GB (6 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 Desktop Memory Model CMZ24GX3M6A1600C9
     
    How about 48GB DDR3 16000 2000MHz RAM like this:
    Crucial Ballistix 4GB 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000) Desktop Memory w/Thermal Sensor Model BL51264FN2001 
     
    Again, whatever someone can do to help me to figure out the BEST RAM out there would be greatly appreciated. Thank you, later, PNugg… :)
     
    PS - I couldn't put newegg's web links on here because of restrictions on this site, but you can look it up to see it for yourself. Again, thanks...

    with the 5645's you should be able to hit 3.6-3.8, but 3.8 will be harder cause you will need 200bclock with turbo for 19x multi
     
    for ram 48gb is overkill unless you really need it or want it.
    I personally suggest any 1600 ram; basically get the best deal available when you're ready to buy. no need for higher spd ram or lower latency ram IMO.
     
    I personally run mushkin, never a problem with gskill or corsair either. I have run crucial in the past without issue as well, but that was ddr2.

    Thanks Infrnl,
    I appreciate the advice, thank you. I have 24GB kit of G.Skill Ripjaws DDR 3 12800 - 1600MHz. I should get more then. I render videos using Final Cut Pro, Apple Motion, Photoshop, etc. That's why I need it. Thanks again... If anyone else can contribute as well that would be great... :-)

    Mines are running at 3.8GHz, 205 BCLK is not stable for me, all air cooled. Get the 48 GB of RAM, it's very cheap now. GSkill kit running without any issue.

    EVGA SR2 at 200 Bclk, default voltages
    2xXeon E5645 at 3800MHz Turbo on, default voltages, 2xCoolerMaster V6GT

    Thanks MassD,
    How funny !!!  You basically have the same equipment set up that I have; with the exception of I have a Koolance water-cooling setup. I have the same chips, RAM, PSU & GPU (but it's an EVGA GTX 480 Superclocked card). But again, very similar set up.
     
    Can you believe it. 4 months ago I got 24GB of RAM for $300; now it's $160.00. What a trip !!! But I still don't feel like I got taken because just a year ago this same ram was $900+ !!! So even at $300 it was worth it.
     
    Don't know what kind of case you're using but I'm going to tackle the Silverstone (SS) TJ11. Of course some modding has to occur, but fortunately talking with tech guys at SS they had a used case that has a ding or two that I can fix, they gave to me at a price that I couldn't say no to.  One of the main reasons why I chose that case was because of two main reasons.
    1) Airflow; it's VERTICAL baby, and I love it. I already have the FT02 case and was hoping for a case that was tall enough to fit mobo, so we'll see once I get it. Plus, I think (unless I'm wrong here), this will be one of the first SR-2's that is vertical along with the airflow fans.
    2) The SS TJ11 has NO RIVETS !!! ALL SCREWS !!! Which makes it nice for taking things apart and modding. Again, we'll see what happens once I get it. Hopefully it won't be too hard to put together... 
     
    Here's my current system setup, (I just love this case and hope TJ11 will be a nice fit for the SR-2):

    Wow very nice rig, Punk!  I also may be moving to E5645s shortly from my E54620s so I will post any different results.  If I can at least get them to 3.6 like my E5620s, I'll be happy.

    Thanks !!! Well, when you get a moment then take a look at the new HACKINBEAST that I recently put together. Tell me what you think. BTW, you also have sweet SR-2 Setup as well. Nice...

    Ah cool.  I did try doing the Hackintosh route once.  Could get 10.6 up but it took forever to patch properly to even get the MacPro designation to show up.  I finally got the frequency to show up being close, and it to see all my RAM, but the GPUs, NIC, and stuff was a no-go.  Congrats on having a nice stable Mac system.

    Hello,
     
    Here is where I'm at:
     
    3772 MHz during IBT, waiting for the Gflops right now.  Same speed folding or Primes.  198.5 x19, though, at idle, it will show over 4100 when the multiplier kicks up to x21 ,.
     
    (I wonder about the CPU load for a canard validation I just saw on HWBOT, of 4637 MHz, 220bclk. x21.)  Is there a board that can force it to hold x21 on all threads under load?  If not, then the guy mentioned, Wolf, would then be "working" at about 4125, still fabulous!
     
    I haven't had time or talent enough to try all the tweaks to get above 199, (my wall with the largely automated settings.  I only set the Vcore to 1.350.
     
    I just got 75.4 Gflops in IBT.  Now I'm idling at 4169 on the two fast x21 cores.
     
    I suppose I'll have to start looking at all those variables, from which the factorial product would be about beaucoup tens of thousands of combos!
     
    I might just stop at bclk 205-210 if I could even manage to get that high.  :)
     
    Bruce
     
    P.S. I don't think I have enough clout to have a "system details", so I'll add this:
     
    I forgot to mention the temps earlier; During Prime95 mixed FFTs, they vary per core from low 50s to low 60sC, which I believe to be equivalent to TCase of about high 40s to high 50s, 5-7C lower than core.  A mystery there with a lot of conjecture...

    Machine:
    SR2/1A, (forgot the BIOS and how to get it to tell me)
    5645s are 2C Rev B1 running at 1.352 Vcore
    RAM is 1600 MHz Crucial with no heat spreaders! 6 x 4Gb for 24 Gb total
    Corsair AX1200 PSU
    Two Cooler Master 212 EVOs each with an extraction fan at 2000 rpm
    Case is a Rosewill Blackhawk Ultra; two big, (blade dia. 7-3/4 in.), extraction fans on top, one more blowing in on the side panel; two 140mm fans front panel intake, two more back of the drive bay, one more as an exhaust near the top of the back panel; one slim 120mm on the side under CPU1.
    Has a GTX 560 GPU card, but I don't game.
    Crucial 120Gb SSD, Seagate 2 Tb HDD
     
    Folds -bigadv at 170K PPD, or a 6903 in 46 hrs.

    Hi Thanks! that would be me. Had you looked at the HWBot or CPUZ link closely it shows 2 cores 4 threads.
    You can drop force the CPU to 1 or 2 cores and use the 21x multiplier or 3 or 4 cores and use 20x multiplier.
     I had wrote up a long possibly helpful post but it disappeared some how as I tried to do a preview before posting.
    Oh well maybe I'll feel up to re-typing all that again once I get over being flusterated over loosing it all. lol
     
    Edit: oh ya you might want to also note that was done on a x58 chipset witch OC's better than the SR2 5520 chipset.
    That was more or less a max OC run, but was stable enough to run wprime 32 test and a few other short benchmarks.
    May could have ran other test, but temps hit mid 70c on air cooling while running the short test, idle was 45 to 50c.
    You can have a look at my thread about SR2 and the E5645+E5620 here: http://forums.evga.com/tm.aspx?m=1504334
    Might be something helpful for you there. Good luck with the OC.

    probably stable at around 180-195 bus, use turbo.
    200 bus is hard to pull with faster 56xx than 563x
    A lot of bios settings to get it right..
    people talking about 215-230 bus, but that is not on SR2 with dual hexa.
    Every SR2 is different so u may got lucky :-)
    If u render so use watercooling, daaam hot   
     

    2x EVGA SR-2 with X5690, 48/96GB RAM.
    1x intel Platinum 48core system with 9GPUS, 192GB ram all cpus\gpus watercooled
