overclocking - Page 3

post #21 of 34
Ok sounds like a smart move If i were you I would move my ram up to 1600 and try and get the QPI/VTT VOltages as low as possible. GO in steps of .01 first then once you are no longer stable bump it up one notch or .005 and then see if you are stable. Then do the same with your CPU PLL voltage and your DVID (start at -.005) and then keep going down until you are no longer stable. Good luck with the chip. Once you are at the lowest possible DVID, CPU PLL, QPI/VTT, then now you can leave your multi at stock 33x, enable Turbo boost technology (this is under the menu with the Turbo by core sectoin, I think advanced frequency settings. also enable C1E, EIST, C3/C6 and when you boot into your os you should see your idle at .09 and your load at what ever it was before you enabled the c states

One thing to note is that sometimes when you enable the c states (C1E, EIST C3 C6) your voltage at idle might drop too low and cause you to crash. If this happens just slowly upp your DVID by .005 and try to switch between idle and load several times in order to replicate the bsod. (maybe by starting and stoping IBT maximum a couple of times and open Fire fox or sometime IDK get creative. This is only if you have trouble with your IDLE VOltage becoming too low.

Finally once you are completely stable I would then run Prime 95 for 12+ hours and IBT for 10 or so passes on maximum. This will be pretty much the hardest 13 hours of your computers life but you need to know if it is up to it so stress away!

so first bump 1600 the ram and lower qpi by one step and test for 5 min or so and ibt twice..
next lower pll cpu volt
then dvid.
ill let you know by tomm what i get it down to,
whats a good volt/dvid for 4.6ghz

So i dropped my QPI back to stock levels.. 1.050 i believe is the stock. The 4.6ghz still ran stable. I also upped the ram to 1600mhz. I then started dropping the DVID and i went to -.015 or -.020. but idk how to change my cpu pll. In my advanced voltage settings my voltage core is at Normal like you told me put it. Do i scroll down to cpu pll where it says 1.8v. im a little confused as what to do here

basically at load now im droppin to 1.272 from 1.32 so i can see that the dvid as im lowering it is making my base voltage droop more and more under load. Should i keep doing that until it gets unstable and then how do i change my base voltage. Thats the part i dont understand.

Yes that is correct the reason I am telling you to drop your cpu pll is because It can potentially lower your Vcore. This also helped my system become a little more stable but that is not related in this situation because you do not have CPU PLL Overvoltage enabled. Did you turn on. C1E C6 and C3 and EIST? If not do so now. You may have trouble getting stable after you enable the c states and EISTif you do just up you dvid in incriments of .005. When lowering your cpu pll overvoltage from 1.80 I would lower it in increments of .010 or 2 steps at a time. until you are no longer stable then upp it by .005 (if this is even possible if not up i by one step)

This is something I would suggest forming an opinion on by reading up a little. HERE is a post on this topic you can start. this is not the first I have heard of this either there are several articles scatterd throughout the interent that talk about how Droop is good with Intel. In the past an overclockers job was mainly to keep the droop to as little as possible but with sandy bridge Intel went as far as to including a droop into their speck sheets. I forget what the specification is for droop. If you are too lazy and just want me to answer for you then I would do what you are doing now keep the droop and just see how low you can get the DVID. One thing to remember is you do not change the base voltage. If I said that you needed to then It was an accident because you can not change the base voltage directly you change the dynamic voltage which in tern either lowers or raises the "base voltage" or VID

alright so i dropped my cpu pll from 1.8 to 1.7v and its still running stable.

338'

1. my core V on cpuz is at 1.32-1.308v regular and 1.26v under load. Im starting to see the load V go down but my regular core V is not going down as much. is that normal?
2. should i keep dropping till it gets stable?
3. My Dvid is still only at -.020 should i keep dropping that also or just leave it and keep working on step one?
4. Ill enable the C's when i get back just wanna make sure i got this part down

Keep dropping all of the voltages individually until you are no longer stable then increase them by one step Probably by .005. do this with CPU PLL voltage first then with qpi/vtt then with DVID one at a time.

1. Yes this is normal.
2. Do you mean Unstable; as in your are 100% stable now and you are dropping your cpu pll until you reach unstabliity right? Cause if so then yes
3. Yes after you drop your cpu pll try dropping your dvid as well. One thing to do is maybe drop the cpu pll to maybe 1.695 and then start lowering your DVID and see if your idle vcore or VID is lowered any. Try this and report back and see fi lowering your dvid say .010 is enough to lower your VID or Vcore. If your VID is lowered then try to see how low you can go with your DVID. If your VID does not go down then try lowering your cpu PLL voltage some more.

So i changed my heatsink to a cheaper version of the one i had to save some money and to get a smaller heatsink
Its overall working great. But for some reason my 1.7v cpu pll is not stable. Doubt its a coincidence or anything but i am going to run one more burn test to see if it is unstable. If so ill start raising it some more to get to a stable number. Maybe as i work on the Dvid my cpu pll will start to go down. ill update by tomm =]

Try turning it up, you really should have no problem lowering cpu pll on the GB LGA1155 boards. I know hicookie runs his at 1.3v., no joke.

FWIW The lowest I could get mine was 1.78. I Once you get that lower everything else and turn on the c states and you should be good to go. make sure you also turn on turbo boost. I think it is under the advanced frequency settings.

ok well i know the ranged for cpu pll whats the usual ranges for dvid. Mines at -.025 should i keep going in the negatives. is there that much more to drop?
