Opteron 165 vs 170

My question is basically is the upgrade to the 170 worth it for overclocking?

I've heard that the 170 is a better chip than the 165, espeacially for overcloking. Is this true and is it worth the extra money?

And also what is the E4/E6 stepping that people were talking about?

  1. well e4 and e6 apply to the venice(e6) and san diego(e4) and yes it it worth it for ocing very worth it :lol:

    False, the 170 is not better, it just has a 10x multiplyer. If you dont get a good motherboard then its hard to oc with a 9x multiplyer(165) vs 10x (170). I have my opty 165 running @ 2.8ghz 311x9 1.45 volts :)
  3. What motherboard do you have/ Would you recommend for ocing with the 165?

    dfi landparty ultra d its a 1 pci-e 16x(129 @ newegg.com

    they also make sli and crossfire boards check newegg.com
  5. what are you looking to do with this processor?

    in terms of real-world results for a casual user, the difference between a 165 and 170 is nonexistent - the 165 can generally give you a good 2.6/2.7Ghz, while the 170 might generally give u a marginally better results, perhaps 2.7/2.8. if you are price-conscious (ie. what you do is not important enough for you to spend $XXX for an extra ~100mhz), then the 165 is the way for you to go.

    they're both great processors, and at their fullest oc potential on air (assuming a good aftermarket hsf), the difference is extremely marginal

    the 170 uses a 10X multiplier, so its a 1:1 overclock, so your FSB is your processor speed.

    the 170 uses a 10X multiplier, so its a 1:1 overclock, so your FSB is your processor speed.

    just got done telling someone else about the 1:1 ratio. it does not make a big difference with the a64/opteron processors. Using a memory divider and your all good, im running 289x9 give me 2.6ghz with a 7/10 divider so memory is running @ 2-2-2-5 @ddr 404

    when using older athlon xp and p4 setups they dont have the onchip memory controler, so it has to go through the motherboard 1st then the cpu. with a64/opterons the cpu has direct access to the ram so thats why its much faster than any p4 or athlon xp setup. Thats why ddr2 667 is slower than ddr1 400 but, ddr2 800 and 1066 is faster than ddr1 @ 400mhz.
  8. well I've decided - the 165 and DFI lanpart ultra d.

    Thanks for the help! :D
  9. with my 4800+ i run it at 10X multiplier, and i run the FSB at 282, i also use ddr500 so i can oc the ram, and not worry about stability.

    NOW 9X multiplier is fine, but if you really want to clock your chip you want at least a 10X due to motherboard issues. most mobo's cant get stability over 260-280 FSB MHz. so if you have a 9X multiplier, your limiting your overclock prematurly. 9X280=2520. and believe me, that processor CAN go higher then 2.5GHz you will limit yourself with the 9X multiplier. with a 1:1 you can go to 2.8GHz with the same FSB speed. so if you told someone else 9X is ok, you were incorrect.

    asus a8n32-sli is known to go to 300MHz stable, this is why i bought this board.
  10. 95% of all DFI mobo's run 318mhz fsb/htt no problem, they all do 300 (you get what you pay for).
  11. ok thats 2862, the opteron can go to 3.0GHz without mutch work. you will never see the full potental of an opteron 165 for that reason, where a 170 {same basic chip} can see the 3ghz with the 10X multiplier.
  12. thats true, if it can do 3ghz (you need water or higher to hit 3ghz). im doing 2.8 on air with stock cooler and 1.45volts 200mhz wont make that much a difference, but I hear what ur saying. I see you have water cooling on your 4800+ @ 2.8ghz can it hit 3 or you havent tried yet?

    it doesent want to do 3ghz, dont know why... and i have it at 1.575 to do this... i want to downgrade to an opti 170 actually...
