Overclocking my memories

hi all .

my new memories just arrived. and i'd like to make they work on top speed. so how should i proceed on setup to have it work just as fast as it can?

my motherboard is a ASUS M3A78
processor is a phenom II 940
memory is corsair ddr 800 xms2 4x2gb

thanks :)

  1. Hi

    Add a fan or put them on water if you want top speed, cool ram=faster ram.
  2. well, temperture is ok here.
  3. Hi

    Let me give you a good example. I'm running 4Gb 2x2 HyperX 1066. 1066 ram is 800 ram on steroids basically. Very seldom can anyone get 1066 ram to run at 1066, usually 1000MHz is the most you get out of it. I bought this ram and ThermalTake ram water blocks at the same time. The sticks ran at 2.3v, 5, 5, 5, 15, 2t, 1066MHz without any issues whatsoever. Unfortunately I should have bought better water blocks and to any body reading this don't be a fool like I was and waste your money on the ThermalTake ram water block, they leak, no barb should have sent up red flags. Anyway, I'm currently waiting on my Koolance RAM-35 water blocks. Without the water I can only get 2.1v, 900MHz out of the same ram.
  4. ok man, iam running mine at 900 i think it is ok..i'd like to improve the latency. frequency is ok i think
  5. You're doing real good, DDR2 800@900MHz. I'm not sure how much more you can get out of that but have you tried bumping it up already? I'm not sure which CAS you have you didn't give the model#. Consair has 6400 XMS2 ram with CAS 4 & 5. If you're running CAS 4 try 5, 5, 5, 15 (or 18), 2T. If you're running CAS 5, try 6, 6, 6, 15 (or 18), 2T. You may have to slightly raise your voltage to support a higher CAS but I would try it without first.
  6. mine is 5. not 4

    it is 5-5-5-17 now.so u saying that 6-6-6-15 is better?
  7. 6-6-6-15 or 18 would be the next CAS up, I wouldn't push them up to CAS 7 unless others with your ram post with their experiences of this ram. Personally I wouldn't push then up to a CAS 6 but your an enthusiast, I see that and can certainly relate. Worst case scenario (2nd to worst case scenario actually), pull the CMOS battery and reset.
  8. well after lot of tests. now it is running at 940Mhz latency is 5-5-5-14

    and processor is at 3.5 where origial is 3.0 .

    it is really fast now, but theres something to me to do for this get faster than this? lol
  9. I give you a lot of credit for getting those 800 sticks to run at 940MHz. Now, have you tested for stability at that speed.

    Test:
    1. Archive a 100Mb file at max compression
    2. Run Orthos for a minimum of 30 minutes.
    3. Run Crysis for awhile or a game that uses heavy resources.
    4. Cold boot test. Shut the computer down every night and check the bootup the next day for a several days.
  10. i made all tests, except that cold boot test, but ill do, anyway, maybe i can icrease a bit more? if i can where should i? :)
  11. Your crazy man! A cool crazy though.
  12. hahahah, sure iam, well iam brazilian lol, and everyone i know from internet says: " now i know why ur crazy hehe"

    but serious, is there a way? lol
  13. I run Intel so I don't know much about OCing AMD processors. But either way you should still be able to disable these features in the bios for better performance:

    Spread Spectrum Control: All Disabled
    CPU Internal Thermal Control: Disabled
    Limit CPUID MaxVal=Disabled
    Enhanced C1(C1E)=Disabled
    CPU C State Capability=Disabled
    Execute Disable Bit=Disabled
    Virtualization Technology=Disabled
    SpeedStep Technology=Disabled

    These features may or may not appear in your bios because we have different chips but we both have ASUS boards. You can also raise your VCore to see if you can get a little more out of your FSB. NB and SB may also have to be raised but only if necessary. Go to the hardware monitor in the bios and see where your VCore is at now before you manually raise it. I don't know anything about your cooling so keep an eye on your temps.

    AMD Phenom II X4 940 Deneb 3.0GHz
    Voltage range: 0.875-1.5V

  14. ok man ill try and post soon, just to let you know, my cooler is this one.

  15. i did everything, and works nice. temperature isnot so good in my opnion.

    it is like 50C in idle..aff well here where i live is too hot..like 35C everyday and somedays goes to 40C easly ;(
  16. I run at room temp with no OC. But I have to crank my VCore up to raise the FSB and my CPU temp rises, same thing with my GPU's, I OC them to. Shoot me some final results.
  17. Disreagard, posted on the wrong page.
  18. thats what i thought. lol.


    btw, i was searching on net..and i heard very well from de cooler master v8..i have a friend comming from spain in the next month..do you think it is worth?

    46 euros.

    here in brazil is like 100 cos of the tax import..so the time to me buy is now.. so should i?
  19. hmmm i heard very well from that V8..and iam really sad here, i spent a good money on this asus and now i see that it isnot so good for overclocking...arg.. maybe thats is good in filand, sweden..or something..not here in brazil lol
  20. The ThermalRight is probably the best for air cooling from the links I posted. I have a Freezer Pro on my 2nd rig (1st link) which is a good cooler but it only has a 92mm fan compared to the ThermalRight 120mm fan. Water is another option just depends if that's your thing or not and how much you want to spend.
  21. well i can spend how much how as i need. i just want it cool hehe.
  22. That's why I recommended the water because I know your crazy just like I am, you got to be a little crazy to stick water inside of a computer. If you need any help with air or water just yell, I'm chillin today.
  23. hmm do you use msn? let me know then i shoot you by pm with my adress
  24. No, I was talking about right here. We're not doing anything wrong and we are on topic.
  25. sure. i know we are not doing anything wrog..just asked because we could chat more about those things, but nevermind.

    to put water cooler, i need to look for a decent case also right?
  26. My mistake, I never thought about that. But if you have a mid tower you can still make it work with an external kit and save yourself some money.

    If you make a decision on water let me know because I have a question to ask.
  27. i was looking for this one, a store in spain, and i found awesome, price , since it comes already with watercooler inside. and ill ask my friend whos in spain if he could bring it to me.

    take a look
  28. That is okay if you plan on cooling your CPU only. Ask yourself this question, will I change my mind later and want my video cards and other hardware cooled as well. I just don't want to make the mistakes I made and in up spending a ton of money for nothing. Look at my specs below, I have the same case in a full tower, I bought the BigWater kit separately. It was okay but beyond the CPU its worthless, if you add video cards your temps go right back to air cooling. The only thing my BigWater cools now is my ram. As far as the case is concerned, The Armor is a great case. It looks good and the engineering is 2nd to none. If you know for sure all you want to cool is your CPU its a good deal, go for it.. But if you plan on adding additional hardware to the loop now would be a good time to position yourself for that.
  29. I wanted to add one thing. That water cooling unit takes up 3 drive bays, I have the 2 drive bay unit. This means you will only be able to use 2 drive bays because you have to leave the bay directly under it open for air flow. One more thing if you purchase this unit make sure it comes with water cooing and not just optimized for water cooling, call them to confirm.
  30. well i wont mind for cooling if it didnot impact on performance, otherwise, i'd let burn xD, but since i need low temperatures to have a nice performance, iam going for this and i think that CPU is the most important no? so ye iam planning cooling cpu only(with water of course) i have just one dvd driver then bay wont be a problem. my grafic cards is a radeon 3850, and right now temeperture is on 47 GPU , thats the temperature of GC?
  31. That's cool. You can still expand later on down the road if you want. My bigWater is still in use serving a purpose, I don't believing in wasting anything can't afford to. If you have any questions just ask, if not let me know how everything went.
  32. well, iam like 90% decided at buying this case, tomorrow ill make contact to my friend whos in spain to know if he can bring it to me, hes comming around 15 of july, not so late, i can wait hehe

    one case like this here, coast like $500, brazil has a big tax for importation products ;(
  33. I'll keep the email notification enabled on this thread so you can let me how it went.
  34. sure, thanks a lot for the help.
