  1. I agree with you there Daddyjax...it does seem strange....1.65V is a huge amount of voltage and would have a big increase in both idle and load temps. That is not to say that he is lying...my guess is that you have duff temp sensors.
  2. Those temps are phenomenal! Are you sure they are right ??
  3. Here are my results from my new 3700 (a KACAE 0602GPMW). At stock volts of 1.392V it is prime stable at 3.11Ghz on air cooling. Here is a pic of her in action: If i can get the temps down a little bit then maybe I can push a bit more Vcore and increase the stable Overclock to 3.2Ghz
  4. Those temps seem fine...and the idle temp seems very good. In response to DragonTattooz's statement, yes it is easily possible to get 28 idle with air, as long as your ambient temps are around 23C (normal sort of temps) and you have a decent air cooler, good air flow and nice neat cabling. My old 3700 used to do 26-28C idle on air cooling, but my new 3700 is a different kettle of fish...does 31-33 idle with stock volts!
  5. Another thing which is strange is that my TDP on Tcasemax is 55.9W, whereas yours is 30W. This difference cannot just be to do with the extra 200MHz overclock on my CPU can it?! Also, my Tcasemax temp is 61C, apart from that everything else is the same. What does the Tcasemax temp mean?
  6. My God that makes me jealous. If I had idles of 26C I could throw in 1.55V into the CPU, which would allow me to break 3.2Ghz, prime stable. It almost makes me wanna try the stock hsf to see if a miracle happens and it lowers my load/idles.
  7. Seriously mate, are those temperatures right?? How on earth is it possible to get 24C idle with 1.65V with ambients of 26C? I wish my idles were that low.
  8. Those temps are incredible! Are you sure your room temp is 27C? I thought it would be impossible to idle lower than your room temp?! At 1.65V my CPU would run at around 60C (not joking either!), and I have superior air cooling to the stock cooler. V.v.v. wierd.
  9. Thanks Michael Here is a little Prime I have been working on at my stock volts and 3.11Ghz (notice the better temps this time) : For some reason the temps on this CPU arent very good. At idle I get around 30C at stock volts, hence my load temps are around 40-42C. This gets far worse when I increase the Vcore, and hence the chip is not scaling well with voltage at the moment (was prime stable at 3.145Ghz at 1.44V). The strange this is that my old 3700 had great temps at 1.54V...idle was 28C and load was 40C. I cannot understand why the new chip is running so hot. I have reseated my TT BT loads of times with varying amounts of AS5 and still no luck. If I was brave I would remove the IHS, but I cant imagine knackering this CPU, so I have wussed out (for now!).
  10. Thx. I have air cooling...but a pretty good air cooling setup....Thermaltake Big Typhoon with thunderblade fan, 5 case fans and nice neat cabling. You should get a better cooler, such as the one I have or something like an AC Freezer 64, then you might be able to push it further.
  11. I think you might be in luck mate. I have a KACAE 0602GPMW and it does 3.11Ghz at stock volts (1.392V) on air cooling, and this is totally prime stable. Here is a pic I took of my OC last week (my temps have dropped since then so I have managed to go up to 1.392V on the same Vcore): Your CPU is a week older than mine, so it should do pretty well on stock volts (maybe 3.0GHz depending on the cooling)
  12. Thanks Tmod. In your opinion, what is the best nf4 bios? Which one would you recommend for the highest FSB/HTT? Cheers
  13. But arent there a few versions of the 704-2BT bios? Is the one on the CD definitely OCZTony's version which everyone seems to rave about?
  14. Hi, just wanted to know if the version of the 704-2BT bios on TMod's CD is the version which OCZTony created in the sticky thread?
  15. Hi Kandoo, just to say thanks as the chipset fan arrived safe and sound after its trip across the pond. Thanks very much and I hope you get some kind of generosity award from the moderators (nudge, nudge). Cheers, Rusty
  16. Cjoe when you talk about voltage variations, what sort of fluctuations are we talking? My Vcore, when measure with a multimetre, is 1.51-1.52 at idle and 1.54 on full load. Is this the sort of thing you are talking about? Also, I take it you mean the rail voltages as well. I thought that variance in voltages was down to the voltage regulator of the motherboard as well as the quality/power of your PSU? There has been a flurry of voting during the last few hours, with the categories of 1.575-1.60 and 1.60-1.625 taking the lead. Thanks for all the votes/help, keep them coming.
  17. I have heard that figure of 10-15% before (in custom Pc magazine if I remember rightly). So that would mean for my 3700 sandy (stock Vcore of 1.40V) the safe voltage might be between 1.54V-1.61V. This seems to kind of agree with the poll so far, however the voters are at the top end of this margin with the most popular categories being 1.6-1.65V.
  18. I think a decent, "safe" lifespan for a CPU would be 3 years, however that does not necessarily mean that the CPU has to be you main CPU for 3 years. Although I may change my CPU in 2 years or less, I would still like to be able to sell the CPU or keep it for a bit longer. As for usage, I am talking about day to day use, such as surfing the web, along with things like gaming. cjoe7 I didnt realise how important a steady source of electricity was. By electricity, do you mean voltage, and hence that it is important for your Vcore or Vdimm not to vary erratically? The poll is showing some interesting results at the moment, with 1.625-1.650 topping the charts at this very second in time. This is higher than I was expecting. Keep the votes coming thick and fast.....
  19. Sorry about that, I was talking mainly about a single core AMD CPU (such as my 3700 SD). Also, when I say "safe" I mean a voltage which will give the CPU a decent lifespan such as 3-4 years not 6 months or 10 years.
  20. I have been trying to find out what the max safe CPU voltage is and have had a lot if mixed responses...on overclock.net the general opinion seems to be between 1.575-1.65V. What do the people of DFI street think? Basically, what is the maximum safe Vcore for an AMD CPU (such as a AMD 64 3200-4000, and X2 or an opteron) if temps were not an issue and were kept under the 45-50C safety barrier by a good air/water cooling setup (not an extreme setup like phase change)???
  21. I tried doing the reading using a molex as my grounding source. This gave on average a reading of 0.02V higher than the reading taken using the proper method. This is due to what supershanks mentioned....here is a bit of theory Using the formula V=IxR, if the current (I) is kept constant by the power supply in the computer, and the resistance ® increases due to there being more wires and circuitry between the Vcore measuring point and the grounding point, the IxR will be a bigger value therefore V will be larger.
  22. Neither the bios or windows (i.e. CPUz) is accurate for measuring Vcore. When I tested the Vcore with a multimeter I found that the actual reading was about 0.05V higher than CPUz and 0.03V higher than the Bios, so at 1.66V you might actually be running at 1.70V!!!
  23. That is so true, also they could have made the measuring points slightly further away from each other on the board....my hands were shaking like a leaf. The measuring points are so small it felt like I was using a golf club as a probe.
  24. Right...I have taken the readings by the proper way (not the molex way) and they show that you CANNOT trust windows in the slightest. I set the Vcore at 1.525 in the bios. In windows it shows up as 1.52V, in the bios it shows as 1.54V, but the voltmeter reads 1.55V when idle and 1.57V when on full load. THat is a difference if up to .05V! Now for the Vdimm. In the bios I set the Vdimm at 2.70V. In windows this value reads 2.7V, in bios it reads 2.74V but on the voltmeter it reads 2.77V at both idle and load. A difference of 0.07V! This just proves how unreliable both the bios and windows are at reading voltages.
  25. p.s. I take it doesnt matter which way you connect the probes (i.e. black for Vcore and red for ground and vice versa), one will give a positive voltage and the other a negative reading.
