    Finally built my new i7 920 system!

    nados Level 1

      Hi all - especially Harm and JIm for their support and advice...

       

      I received the compontents for my new i7 920 system yesterday and built today.

       

      components:

      i7 920 D0 stepping

      PP Power & cooling 910 watt psu

      Asus P6T mb

      2 x (3x2g) sets of matching DDR3 1333 ram for 12gb

      2 x DVD rw drives

      1 x Blu-Ray rw drive

      1 x 160gb WD system drive

      1 x 500gb Seagate cache/storage drive

      2 x 500gb Seagate work drives totaling 1tb - raid 0

       

      So far so good - no problems!

       

      I was able to boot the new hardware from my old system drive that ran under an AMD Athlon x64 6000 processor and a Biostar A770 A2+ mb. I just installed the new Asus mb drivers and things look good so far. I have not tweaked anything in the bios yet other then the date/time and boot device and order. Eventually, I will install a new copy of Vista x64 OS and CS4 on my new i7 system and rebuild a my NLE, but for now - i'm happy.

       

      I can't wait to see how much faster some rendering and transcoding gets!

       

      I have attached some CPU-Z screen captures so you can see some numbers. Notice that the ram type in the "SPD/Max. Bandwidth box" is listed as PC3-10700  and PC3-10700H and not just 10600?

       

      Also, because of the matched sets, slots 1/3/5 all show the same Timings Table Frequency for that set and slots 2/4/6 show another Frequency for that set.

          Going from my old P4 to an i7 920, I saw a 4x to 6x speed improvement with various encodings.  You won't be disappointed.

            That looks good! Congrats.

             

            Once you have setup your system you can fine-tune/overclock it very nicely. Let us know how you get along with the new system and what help you may need when fine-tuning. There are quite a number of options, but first get everything running.

             

            Enjoy.

              HI all,

               

              Ok, things are stable at default settings. I'd like to try OC'ing - just for fun - as far as i can without changing the OV (over voltage) jumper settings on the mb. The bios AI Tweaker menu is all set to auto by default, so i don't know what can be done.

               

              In any case, any help on OC'ing would be appreciated. I'll try it for fun but will probably return it back to normal for editing.

                Carefully, very carefully, go through the options in the mobo User Guide. Probably this is chapter 3, section 4 about the AI Tweaker settings.

                 

                Set the AI Overclock Timer to manual.

                Leave the CPU Ratio Setting to Auto.

                Leave all the other settings at default, apart from BCLK settings. Set this to 172. Do not change anything else. Press F10 to save and reboot.

                 

                You have now overclocked your system to 3.6 GHz, so keep a close watch on your temperatures, specially the core temperature with Speedfan or HWMonitor.

                 

                This is very basic overclocking and chances are that will suffice for normal NLE work. If you want to go for more extreme overclocking (to use your DDR3 to full potential, for instance) it get's a bit more complicated, but start here.

                  Ok...

                   

                  What about using the windows based AI Tweaker Suite - or is it better to do it directly in the bios?

                    If you mean the TurboV application, like shown here, it is a great way to test various settings. Be sure to check both CPU-Z and HWMonitor regularly.

                    Once you know which settings you want, I would set those in BIOS and use this program for instant changes to your settings.

                      Ok...

                       

                      I installed AI Suite with Fan Xpert, EPU-6 engine and TurboV.

                       

                      I don't know if EPU-6engine will affect any thing - should i un-install it? And should i set Fan Xpert to Turbo?

                       

                      Anyway, what do i tweak in TurboV?

                       

                      There is no AI OverClock Timer option or setting?

                       

                      I set BCLK Freq to 172.

                        Now check CPU-Z. It should read something like this:

                          I don't use it. I prefer manual controls.

                           

                          Anyway, what do i tweak in TurboV?

                           

                          Essentially, you use it to fine tune your BCLK and vCore settings, which you later set more definitely in BIOS. In the earlier post I showed a screenshot of Turbo V with the BCLK set to 178, which reflects the CPU-Z screenshot in my previous post. The other tab in CPU-Z that is quite handy is the memory tab as it shows the timings of your memory.

                           

                          BTW, did you not ask about the impact of matched memory? Your slot 1 and 2 screenshots show that you have different tri-kits. The Crucial memory in the first bank is different from the memory in the 2-nd bank with slightly different timings. Nothing critical, but it shows.

                           

                          I have all my fans run at 100%. I rather have some background noise than a fried PC, especially when OC-ing.

                            Harm,

                             

                            I can't go beyond BCLK 155. If i try to go to 160, i get the BSOD.

                              You said that you set your BCLK to 172. Did you do that in the BIOS?

                               

                              Turvo V is only intended for small adjustments. If you do anything too drastic, the voltage may get in the way of success.

                               

                              My best suggestion is to set the BCLK in BIOS to 172 and leave everything to auto for the time being, apart from the AI Overclock Tuner, which should be set to manual, otherwise you can't set the BCLK to a desired setting. Monitor temperatures while doing this!!!

                                No, I set it in TurboV. I will set it in bios now. thanks.

                                  In bios, I set Tune to manual and BLCK  of 172 in bios worked. Current CPU temp: 38c-40c, system: 36c

                                    When i put the system to work, the cpu gets to about 55 - 60 celsius.

                                      Man, how the hell do you guys get these temps?!  Mine idles at 50+ C, and tops out around 90C.

                                        I have the Antec 300 case with 2 front 120mm, 1 side 120mm, 1 rear 120mm and 1 top 140mm fan - thats how!

                                         

                                        I love that case! I have three of them.

                                          Jim,

                                           

                                          The crux to good cooling starts with the CPU cooler, and then a lot of fans in the case. Of course my system is somewhat loaded, so I may need more fans than average, but I currently have 10 fans and get these idle temperatures with a room temperature of 21 degrees C:

                                           

                                          PC-Temp.jpg

                                           

                                          This is with the CPU running at 3.7 GHz. When under heavy load, core temperatures go up to around 62 C.

                                              What do you all recommend for a good cpu cooler?   I'm currently using the one that came with the i7 920 processor.

                                                For a GOOD CPU cooler I would suggest either the Thermalright Ultra Extreme 120 1366 or the Noctua NH-U12 SE 1366 with push-pull configuration. The Scythe Mugen2 is a good alternative.

                                                 

                                                Here are my idle tempreratures:

                                                 

                                                idle_temp.jpg

                                                and when under some load, while encoding to H.264 BR from a HDV project I get these results:

                                                 

                                                load-temp.jpg

                                                You can see that even with a higher clock speed my CPU load is not up to 100% and my temperatures are around 10 degrees lower.

                                                Around 74 degrees is not worrisome, but the lower the temps are, the better for longevity.

                                                  I noticed that you have configured your SpeedFan Exotics to be displayed in a similar manner to mine - funny!

                                                   

                                                  Also, I noticed that at BLCK 172, the cpu is running at 3440mhz (3.44ghz) not 3600 (3.6ghz) as you thought and as shown on the speedfan image in my previous post. Even yours is running at 3.55ghz not 3.6ghz.  Am i just picking hairs?

                                                   

                                                  Anyway, i used TurboV to tweak it up to BLCK 180. Now the cpu is running at 3.6ghz with a little increase in cpu temp at idle. Is this a problem?

                                                  Also, increasing the BLCK say up to 200, would that be problem as long as the temp is under control?

                                                    With Turbo mode on, the multiplier goes from a standard value of 20 to 21 when the system is loaded.

                                                     

                                                    When you multiply BCLK and the multiplier, ie. 172 x 20 = 3440 MHz, but with Turbo mode on you get 172 x 21 = 3612 MHz.

                                                    Same in my case, 178 x 20 = 3560 MHz, with Turbo mode 178 x 21 = 3738 MHz.

                                                     

                                                    Increasing BCLK settings does impact the vCore voltage, at least when done in BIOS. Not automatically in Turbo-V. But it also impacts memory timings and everything on the southbridge, all the un-core components.

                                                     

                                                    During my testing I found the sweet spot to be around 172-178 BCLK. Going higher caused a higher vCore and reduced timings for memory. The SPD tab in CPU-Z shows at what frequency you throttle back to worse timings. If you want to overclock more, you need to disable Turbo mode in the BIOS, choose a fixed multiplier and set your BCLK for maximum memory rates. It does not seem, at least to me with the limited testing I have done, to be really worthwhile. Sure, on certain benchmarks you may get better scores, but in real life, does it matter?

                                                     

                                                    For your ease of reading my info, I adjusted Speedfan results to mimic yours.

                                                      Please run them both overclocked and with the default BIOS settings. Then see what it brought you in terms of performance.

                                                       

                                                      Running at BCLK 200 from Turbo-V without changing the Vcore and memory voltage to higher levels resulted in my case in instabilities.

                                                      BCLK 180 from Turbo-V without changing any voltages gave me no problems.

                                                      The lower temperatures in comparison to the earlier post are all due to a difference in room temperature. The first one was with room temperature at 25 degrees, this one with 21,5 degrees.
