  1. Thanks for the tip, it really nails Vcore, no drop seen under load, however it is better to set lower Vcore in BIOS with Loadline Calibration enabled otherwise the irrealistically high Vcore is fixed in use, causing the CPU overheating. I mean I had to set 1.7V+ Vcore, because there was the drop under load (went down to 1.66V), with Loadline Calibration enabled it does not go down to 1.66V, nicely stays at 1.7V causing the CPU to run at 80C with water cooling...so Vcore needs to be chosen quite carefully. Maybe the drop is there for some kind of protection?? Actually with Loadline set to Auto despite these drops I never had stability issue and kept the CPU cooler. Regarding the memory I still cannot run them above 1060MHz, I tried 2.4V also, no success. In a P5B I ran them at 1160 @2.2V. Do you know what the Dram Reference Voltage setting in BIOS is good for? These can be set per channel A / channel B respectively, going bellow or above the DRam with some mV.
  2. I have a Zalman 460B-APS, this is quite good at 12V, on the two 12V output it can provide 32A permanent / 42A peak, which equals 500~550W from other brands. Efficiency is also not bad. I popped in a zero performance VGA and the drop is still there. I do not think it is the power supply.
  3. Do not worry I run 3400 MHz with 1.5 V long term, I was just interested if reaching the technical max of a CPU is possible, well yes. This voltage by the way was visible by PC probe as 1.46V in use. An interesting stuff is that in heavy CPU tests Vcore is dropped significantly. When I made the benchmarks with 1.73 V (seen 1.71 in use) it went down to 1.65V. Regarding baking I did not risk long hours stability tests with heavy CPU load, just Everest repeated 5 or 6 times. Only during CPU Mandel made the 76 C peak for short time (few sec) otherwise around 40 - 57 throughout the tests. Watercooling takes away 10 degrees anyway compared to big heatpipe+fan coolers with a very sudden drop in temp when coming out of a CPU test and makes 32 C wo load, just the operating system running. I had a feeling that WC was necessary with this MB, the CPU would have been cooked without it...
  4. Hi, With this Blitz Formula I managed to OC E6600 up to 3874 MHz which I am pretty satisfied with. My question is (that I also saw in the mb official Asus website forum topics) why this motherboard requires such high voltage settings? With 423MHz ext cl, 1058 MHz DDRII I had to apply the following voltages, otherwise the system dumped the total physical memory and crashed: Vcore: 1.737 FSBT: 1.6 NB:1.75 DRAM:2.36 SB/PLL pinned close to default CPU temp 76C!!! under heavy load with water cooling!!! So why such high voltage settings are necessary? Guys are writing on the forum, that a P5K Deluxe can do the same speed e.g. 3.6GHz with lower voltages than Blitz. Is it possible that a new BIOS release will cure this problem or it is normal? Another issue is why I cannot run my 1066MHz Kingstons (PC8500) @ 1066 by setting 1066 in BIOS?? (all settings CPU etc. default or Auto but windows hungs at booting - progress bar). What should I adjust in order to reach higher memory speed than 800MHz default (I tried to increase voltage but did not help, the modules are specified to run @ 800 with 1.8V and @1066 with 2.2V with 5-5-5-15). In my former P5B-V these modules ran @1160MHz without any stability issue @ 1.9V with a latency timing of 5-5-5-15. I would expect this motherboard to handle memory better. Here are some BIOS screenshots, but there are settings I did not see in any of my previous motherboards. Is there anyone out there with another Blitz Formula or Extreme, who is experiencing the same issues?
  5. I tried with an old PATA device, and it was possible to go a bit higher but not much. 125MHz pciE reached with this one, making possible to OC CPU a tiny bit above 3000MHz...not good enough, so I got rid of the P5B-V with onboard graphics (Asus confirmed - also the guys here earlier - the OC limitation of only about 20% because of integrated VGA) and got an Asus Blitz Formula Special Edition. Well this one can OC big time. 3874 MHz reached with E6600 stable in CPU tests however I did not risk this setting without water cooling installed...even with wc temp was 75C during CPU Mandel. A bit High. I also had to adjust VCore to an extreme high value, 1.725 otherwise the system dumped the total memory and crashed during heavy CPU tests. Here is a screenshot and Everest reports, though the first 4 mem test headers written in Hungarian, sorry for that but Everest recognises OS language. In the BLitz BIOS there are some settings I have not seen so far anywhere earlier, like DRAM ref voltage channel A and B stepup/stepdown respectively in mV , DRAM controller voltage setting etc. I will start a new thread with my questions, as we are facing some new features here I guess.

  6. I figured out that I can go higher with CPU clock only if pciE frequency is increased it is for sure, no other way around on this MB. With some diffculties I reached 121MHz without SATA loss, this way going beyond the 329Mhz limit was possible, up to 331... As the bottleneck here is the pciE frequency and SATA devices, I pondered if I plugged in my old PATA HDD with IDE cable maybe it would not lose connectivity above 121 MHz?? In the bios the option is there to increase pciE up to 150 MHz. 1 MHz increment on pciE frequency gives me 2-3MHz increment possibility on CPU clock... Maybe it would work???
  7. Yes, I was also a bit afraid that onboard graphics boards may have some limitations. Well actually I expected worse. At least it reached the rough 3GHz, which is fast enough with current applications nearby, I do not think this CPU @3GHz will be a bottleneck in the near future...
  8. I checked the page, thanks for the tip but it did not work to me... This is strange, the good old overclocking techniques do not work on this motherboard.... The most logical thing that along with frequences voltages are also need to be increased does not apply here. At least I managed to get AI overclocking working, because my windows always hang above 5% at the progress bar... Playing with voltages gave me an idea what about if I nail all the voltages to stock apart fom vcore to fix AI overclocking problem, as I suspected the system puts too high voltage on nb /sb /fsb etc. Well it worked Windows loading was OK at 20%, all tests successful, which means that the system is now able to overclock itself depending on workload up to 2.88GHz without touching anything...Actually this is even more important than having a high peak all time even if it is not needed, like writing this thread... As you can see external clock is chaged within application while it is running (individual everest tests), resulting FSB / memrory speed increase - decrease automtically. I like this... Sorry the frist 4 everest test headers are in Hungarian, these are: 1.Memory read 2.Memory write 3.Memory copy 4. Latency AI_20_.htm
  9. Yes I was running at Auto, with the clock settings you see above worked OK. When it did not work it did not matter which voltage setting I picked stock or the mid value did not help. Only if I increased both frequences CPU and pciE parallel... Otherwise here are the possibilities: Mem: 1.8- 2.45 at 0.05V The Kingston runs at 1066Mhz with 2.2V 5-5-5-15 as default Vcore: 1.25-1.7 at 0.0125V FSB term: 1.2/1.3/1.4/1.5V NB: 1.25/1.35/1.45/1.55V SB: 1.5/1.6/1.7/1.8V ICH8: 1.05/1.15V
  10. Yes, here are the pictures with nearly the max working setting. Of course bios is the latest version. Since these pictures were taken I managed to put pciE frequency at 121 without SATA loss. With some difficulties (about 3 trials) the system loaded then again I could increase the CPU clock further up to 330 (all tests successful), but at 331 the whole desktop became corrupted (discoloured pixels) when Vista loaded, like an overclocked VGA where the memory is beyond the limit....I gues it is because Aero is using 3D. I tried the above clocks with fixed voltages of pcie / nb / sb etc... leaving only vcore at Auto, because I was told with increased CPU clock these values may be set too high with Auto setting, only fixing voltages made possible to reach 121 without SATA loss, but at 122 not detected again.... I also posted the northbridge configuration menu because it is possible that it has somenting to do with onboard VGA (Intel 965G) As you can see I disabled it manually, however it is not functioning by default with pciE card plugged into the primary slot . It is also possible that overall I reached the limitation of my SATA devices that`s why pciE freq will no go higher without drive detection problem. But why this frequency is affecting the external clock max??? I know it from experimenting that it does...if pciE is not set high enough and CPU overclocked, after restart even the monitor (60 Hz LCD) will not turn on. Should I run at 70 Hz and try everything again???
  11. Well, this one is the other way around, I had to increase PCIE frequency to boot. When it did not boot again because I pulled the CPU external clock further up, it helped when increased the PCIE clock again, and on n on...when at 120 pcie clock just would not detect any SATA drives. Maybe this is the limit of SATA devices operation?? By the way here is the Evereset result overclocked (memory not fully pulled up and single channel config yet) Report_C2DUOE6600KHX.htm
  12. Yes, that did not help. My board did not boot at all with increased ext clock unless I increased the PCIE frequency. really tried everything, messing around with memory frequency and all, I did overclock all of my sysems in the past, but this is the first time I had to increase something else apart from CPU clock / vcore. I never touched slot speeds.
  13. Hi, I have a problem with overclocking my external clock on Asus P5B-V as my system did not want to boot at 289 MHz. I figured out that the PCIE frequency had to be also increased to overstep that boundary. It was OK (increasing both step by step) up to 328 ext clock reaching 2.955 GHz on CPU (with 120 MHz PCIE clock), but then @ 329 ext clock the system did not load again. Trying to solve by increasing PCIE clock to 121 - as it worked nicely previously - all the SATA devices were lost (not detected) in BIOS. WHY??? What does PCIE frequency have anything to do with SATA, as far as I know these are handled by the south bridge. ( I have G965 NB integrated graphics but not used currently and ICH8 SB) I have a feeling if I could go higher up with PCIE clock than 120 (the mb is capable of 150) I could increase the CPU clock further up...please help as I want to hit the 3GHz as the minimum.
