ASUS P5B: New Bios HUGE Overclock

ASUS P5B: New BIOS Adds Unlocking & Improved Overclocking

once again the Core 2's prove to be amazing overclockers, but now Asus proves they can work wonders with intels 965 chipset proving that it can be a great overclocker as well!

they take a E6300 from stock 1.86GHz to 3.68GHz!!

This is a 100% bus overclock and it clearly demonstrates the added flexibility of the lower speed Core 2 Duo chips.

    Excuse me while I go dribble outside a PC store. I mean, SuperPI at under 15 mins from a £120 CPU >< Mine still retails for £60 and it takes over an hour.

  2. Very impressive stuff, shame they didnt do extensive benchmarks.
  3. 8O

    Prozac: When are you gonna try that?? :lol:
  4. Can't argue with that. Nice performance gains with the E6300.
  5. Seems like they did much better overclocking than when they used an ASUS P5W DH Deluxe. Too bad they didn't even run the limited benches on the 6600 and 6700. I'd bet the 6300 would beat both of them.
  6. hmm..
    Guess i'll wait a little while longer before buying a motherboard then. Most other companies should follow suit.

    Now we gotta figure out which C2D's are unlocked upwards..

    Can someone clarify for me - it is better to have a low multiplier and high fsb than a low fsb and high multiplier, right? And the higher your FSB is, the more unstable having a high multiplier will be? Is this why people are turning multipliers down and turning the fsb up?
  7. Nice rig, when did you put it together? (havent been paying much attention lately)
  8. Is there something i'm missing?
    If it's better to have a high fsb and lower multiplier so that the whole system & ram runs faster, why don't people just buy the E6300/400 chips with low multipliers?

    Is it simply because the more expensive chips are hand picked and are known to handle higher fsb ratings than the cheap ones when on the same low multiplier?

    wow! my e6400 & p5b is coming this monday, can't wait 8)
  10. you'll have to flash the bios no doubt though...

    I'm tweaking vid card now, and testing it, then I'll move onto the CPU.


    Is it possible to unlock those pipes/shaders on the X1900GT??

    what do you mean? p5b doesn't support c2d out of box?
  13. He means that you'll have to flash your bios to get a downward multiplier. With a lower multiplier, poepl will be able to run their fsb and ram with a 1:1 ratio =D

  15. It's was quite an easy experience for me.

    1. Flash latest bios to a USB flash drive.

    2. Inside the BIOS menu there an Asus Tool Flash program. (I'm at work and can't remember the exact name, but easy to navigate)

    3. The Bios Flash utility program will detect your USB flash drive and you can load your new bios.

    4. Reboot.. Done.

    If you haven’t flashed a bios this way you'll be really happy especially if you’re an old schooler. Trying to find a working 3.5" floppy these days is an arduous task.

    Love this board BTW. So happy to read this review today when I was surfin Anandtech.
  16. thanx for the info
  17. My advice about this board is that it's very selective on DDR2 RAM. Do your homework before you buy. This will save you some time from having to RMA. Other than that, it's very easy to get up and running. Not one problem on my end. I did remove all the crappy thermal putty on the N/S bridge passive coolers. I replaced it with AS5. I havn't seen my mainboard temps over 35-36. My CPU runs a bit hotter around 40 idle at stock speeds. I was somewhat suprised with the Scythe cooler, but I've read this temp is quite common on this mainboard. I just hope the Scythe shows it's stuff when I start hitting a higher FSB.
  18. So for an e6600 with DDR2-6400, you'd want to drop the multiplier to 6 and up the FSB to 400mhz for best performance? You'd still get an overall cpu speed of 2.4ghz, but would be running 1:1 with ram.
    Or would running asynchonous with ram be more beneficial to get higher cpu core speeds? Or should one set the FSB to 400mhz and monkey with the multiplier to find stability? 2.4ghz-3.6??

    Anyone know anything about this?
    If you're going to drop the multi anyway and up the fsb.. surely you should just be buying the cheapest chip with the lowest multiplier?
  21. It'd be really good if someone could put together a Conroe overclocking guide. Currently on my setup, I'm just about to reach X6800 speeds, thinking this was good (well it is sorta).

    It's running at a FSB of 320, with a multiplier of 9, and ratio of 4:5 to get the ram running at stock speed. Even so it was not stable until increasing the voltage on both the CPU and RAM (Gigabyte still haven't got the memory detected right). It would reboot by itself before I could even launch many programs, but now it appears to be running through Prime95 ok.

    I wonder with some good advice how far I could go :twisted: Guide please!? :D
  22. yeh yeah yeah ditto ^^ cause imhaving lots of difficulty choosing between e6400, e4300, x2 4400+,x2 4600+... 300$ mobo plus conroe? or 250mobo with x2?.....
  23. E6600 & P5B or E6400 & DS4 is looking like a solid choice to me.
    I'd pay the extra just to call my chip "Conroe" over "Allendale".. so much better sounding..
  24. :D thnx buuut lol the e6600 is like 600$ over here lol >< plus shouldnt i get the dq6? isnt that better or stick with asus.. ive heard that people have got alot of ram/bios/ other problems with their new boards...

    help me with HWK :D

    i thinking about 250$ of ram..

    If you can get all the retarded AMD fanboys off this forum I might have time finishing it this weekend. :wink:
    For now you'll just have to read how people achieved their result over at XS forum.


    I'm afraid I cant work magic, and even if I could, I'd get rid of all fanboys. Cant wait for the guide, hope it gets stickied!
  26. I just got my P5B Deluxe/WiFi-AP... too bad instead of a E6400, all I have is a P4 640.
  27. All I see on page 4 is that they managed to turn a E6700 into an E6600. I mean, sure - now the E6700's ram is at 1:1.. but the E6600 could have reached 3.6GHz @ 400x9 anyway.. Grats?

    They turned the 3.6GHz E6700 into a 3.47GHz chip.. okay so it's going slower, but our fsb/ram is now going so much faster! Well.. I have seen numerous articles showing how both latency and frequency of memory aren't too beneficial, making only a few fps difference in games at most.

    Is the cpu speed loss worth the fsb being higher?
    Personally I have no idea, since that's where my knowledge ends. Anyone?
  28. Ah, okay then. The hype surrounding this P5B BIOS update clicks with me now as it allows the FSB to go even higher without becoming unstable, since the cpu speed remains around the same or lower.

    Looks like some badass RAM is in order for that board.

    Ta for the explaining wusy.
  29. Interesting to note that the 400/300 have higher speeds & fsb's than the 600/700 with multi's turned down.

    525 fsb @ 3.68GHz on the E6300

    494 fsb @ 3.46GHz on the E6700

  31. The new BIOS 0507 is only applied to P5B Deluxe, not P5B. They are 2 different MB.

    Since generally speaking, 975x is better than 965 and P5B Deluxe is $260, I don't see why I don't wanna choose P5W DH instead.
  32. I'm not sure why I had trouble finding the BIOS 0507 on Asus. I didn't try to hard because was easier to google than to navigate their site. Here is a quick overview of the changes they listed for the new BIOS update.

    Change log:

    1. Support Conroe CPU ratio adjustment
    2. Fix some DDR 800 frequency will show DDR 533
    3. Enhance performance when using NVDIA 7950GX2 VGA card
    4. Fix fail to read files from some ODDs
    5. Fix "Hit ''DEL'' message display" item function fail
    6. Support Max FSB from 500 MHz to 650 MHz

    I was able to find and download here without any problems.

  33. http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&t=197995 for those who don't know, a great guide.

    The one thing I would add is a memory/overclock table. E.g., you have an E6300 and DDR2-800 memory. What FSB do you need to be running 1:1? What likely multiplier, and therefore frequency, will your CPU be at by this point? Perhaps I'm lazy, but I think it would be useful for people to see where their memory purchases might take them.

    Well... it's done.
    I tried my best to communicate it in a way so normal people would hopefully understand.

    If you want me to put even more details into it (there are lots...), tell me here and I'll put into it next weekend.


    Very Nice indeed.
    Well done and thank you for the effort and time required to assemble the guide.


    Peace
  35. changing the multiplier down isnt all that special. The DQ6 lets you lower the multiplier down and has since the F1 bios.
  36. Oh ya? I have a P5N32 SLI SE and it overclocks like crap. I can't break 2.77 with my e6600 and freakin' PC8500 WILDLY expensive Corsair XMS. I'm a little heartbroken because its the ONLY SLI board and i've got 2 Evga 7900GT cards (the 580 Mhz ones). Does anyone have any suggestions for getting some more speed out of the NF4 SLI SE chipset?

    Very nice work, indeed!

    Q.: You state that the first seven aftermarket HSFs allow OC speeds up to 3.4GHz; do you mean both Zalman listed are inferior? (air cooling, that is).


    Cheers!
  38. A slight loss in CPU speed is worth it if it means a 1:1 fSB to ram ratio as well as a faster FSB. The Core2Duo chips arn't affected much by memory timings so one can always loosen up memory timings and increase the transfer rate to matchup with the OCed CPU.
  39. Quote:
    One is an outdated 120mm (7700) design when the other is a very well designed, but expensive, 92mm (9500) heatsink.
    The first 7 HSFs are all based on 120mm w/ new heatpipe designs.

    Performance difference between those two classes becomes greater as you pump more heat (wattage) into them.


    Thanks for the info.
