on my Asus Crosshair III it takes 1.28v to get 3000NB stable. if that helps

If that was to me, it did help now my cpu, cpu nb and ht are overclocked

At the moment I'm at

3.64 ghz 1.45v
cpu pll volts 2.53v
cpu nb 2600 1.25v
ht 2600 1.3v1.3


Volts seem soo high

the 1055 I had did the same clocks with no voltage adjustment

 

[JrRacinFan]

Sounds about right for a c2 720 non black. TBH I wouldnt bother trying to push core further.

 

[LifeOnMars]

Panther, rest assured they are not high volts. This is what I posted in the Maxmemm thread -


It's a cold day and I have been going for a crazy overclock, here's what I got 1.55v on CPU and 1.55 NB!!!! AHHHHH I'm getting another sandybridge setup early next year so not too worried if it goes pop LOL

Yes I am crazy But with the cold winter wind rushing into my room, anything is possible

Well the CPU only goes to 45c and thats if I have my heater on in my room.
Reckon I can push further?

"Sounds about right for a c2 720 non black. TBH I wouldnt bother trying to push core further. "

Cheers for the help man, I think it has a bit more to pull out of it though, 3.78ghz was nearly stable just need to get to grips with what other voltages do, and what are the safe limits etc.

 

[LifeOnMars]

45c is that all? I would therefore try 1.475v on the CPU and one more notch on the CPU/NB. Anywhere up till 55c you are golden. I can actually keep mine stable up to 70c but it's not good for the chip. With those settings above I load up to 66c after 40 passes of IBT, when gaming it only goes up to 52 max with a multitude of CPU hungry games like Bad Company 2 and GTA IV.

Note - Do not use the crazy voltage I have on my CPU/NB........it just needs a helluva alot on mine to get it anywhere near 3000 stable.....but I want it there as the lower latency on the ram makes everything soooo speedy

Don't suppose you remember you're other voltage settings?

I should note, this cpu doesn't have to last me for ever, don't mind pushing volts to 1.55 and NB volts a bit more etc.

I just want more FPS in town on skyrim damn it

Tried unlocking my 4th core for the lulz again, seems with the high voltages I've got I can either have 3.78ghz tripple core or 3.64ghz quad

Cool!

(unlocking the 4th core didn't work at stock speeds with 1.45ghz going into the cpu, so I'm guessing it's the pll voltages or something helping?)


Actually scratch that, still crashes in prime 95 large ffts, small ones are all fine and dandy though.

Should I disable the core again or large ffts uncomming in day to day use? (gaming, listening to music etc)

push more. u are still in ddr2 zone

 

[de.das.dude]

just a question... does athlon ii's support 2000+mhz RAM?

 

[Velvet Wafer]

just a question... does athlon ii's support 2000+mhz RAM?

most probably not, except if you get a very, very good IMC... 1800 seems more likely as max, and it can be as low as 1600/1500 and with worser procs of older steppings, not even that.
AII and PHII needs tight timings tho... higher bandwith beyond 1600 with looser timings is by far not as useful as 1600 modules with very low timings... something like the Gskill Pi Kit with 1600 6-8-6-27 and 1.6v stock.
If you ever used DDR3 at CL5, with a decent bandwith, you will see that lower timings are in fact much crisper

 

[JrRacinFan]

does athlon ii's support 2000+mhz RAM?

Ummm, technically ALL am3 cpu's are 1333 native. You ARE overclocking the IMC even if running 1600mhz dram/ 2000mhz cpu-nb.

 

[de.das.dude]

yes i know that we are OCing both as they are 1333 max. but are phenom ii's more capable of attaining higher frequencies, like 1600MHz?

i just want to tally the effectiveness of PC3128000 kits if i buy for my next build, which may be either an athlon x4 or an phenom x2 (x4BE maybe).

 

[JrRacinFan]

Most I can say is the best you're going to get is 1600 CL6 on am3, anything bandwith wise is just pure overkill with very diminishing results and cl5 on ddr3 is non-existent.


10GBps with 50ns is in theory the best you can expect.

 

[Velvet Wafer]

cl5 on ddr3 is non-existent.

Thats not true, there are just no kits that have that timings stock, with a useable amount of bandwith. but i would bet, that the PIs could easily do 1333 5-5-5, with a little tweaking

 

[LifeOnMars]

@Panther - Only voltages I touch are CPU , CPUNB and RAM. All of the others are stock.

My ram will not do CL 6 timings at any frequency it's like it's hard locked. However, it will do alot higher frequency which combined with a high NB gives me that same latency and crisp feel you can get at lower frequencies with tighter timings.

One thing to note, make sure your ram timings are stable when working on your overclock Panther as one little bad timing/subtiming can throw up errors in CPU stabilty programs. (I'm sure you know that, just making sure)

@ de das dude - I loled at your DDR2 comment

Yep, all other voltages I've never needed to touch and if you do, it's very minimal adjustments.

 

[pantherx12]

So CPU NB over voltage is required even if you don't raise cpu nb speed?

Thanks guys you've been super helpful by the way,

If you don't raise the NB Speed then you can leave the voltage at default. You only raise it if you need to get your NB stable.

i'd push more but my mobo is poop.

You do realise AIDA benches differently don't you - here's mine...I'm still Loling

 

[JrRacinFan]

@Velvet
Ok ok near non-existent and VERY rare.

@LoM
Looks like a winner! What's the furthest you got so far? Is it that?

Nah crazy Lom is going to try for more today. If I don't return it means it went POP!!!

 

[JrRacinFan]

I know I could tweak this a little more, maybe push my cpu/nb closer to 2.7. It's got an average IMC, not a golden chip, just unlockable.

shouldnt ddr3 scores be higher, like in 20's??

 

[JrRacinFan]

Yes but what you're seeing is IMC bottlenecking the ddr3.
