TPU's Core i7 Overclocking and Feedback

[giorgos th.]

have you played with Vpll?mvolts of the clock skew?
f.e. if i give 900mv i stuck at 4700mhz...
if i give 800mv i go all the way to 5ghz....

 

[Fitseries3]

i have tried high and low vcore but it seems to be no different at all. 1.425v runs the same as 1.6v

i have tried pll but it seems to have a negative effect on stability when not set to auto.

i have tried qpi/dram voltage and it helps to some extent but then hinders the stability at higher clocks.

i have tried keeping the vdram .5v over the qpi/dram voltage which seems to be a good way to get stability but quickly becomes worthless and causes instability.

i have tried IOH voltage increase up to 1.53v and it helps for a bit but anything over 1.53v causes the board to not post(like the p5e64 evo did)

i have tried enabling and disabling LLC. neither helps at all.

i have tried the different vreg freq settings but 1000hz seems to be the best. all the others cause bsod on boot.

i have tried reloading 3 different OSes many times and all have the same issue. no stablilty at 192blck+

what now?

 

[giorgos th.]

try a different mobo......

 

[Fitseries3]

dont have the money for one.

 

[giorgos th.]

your bclock maxes out at ~192mhz?
what about turbo?on?off?

 

[Fitseries3]

the first day i had it running i got to 215 but it WILL NOT even post that high now. windows will not load successfully over 192 bclk. turbo on or off. doesnt make a difference.

Binge of course you`ll try.....
that`s the point....
the bottom line is from the point you bought the 920 you`ve got a limit to your o/c.....
no matter what you do you wont go over the barrier of 220-230 bclock....
which means ~4.6-4.8ghz in the best case scenario...

Bottom line is waltzing into a thread and telling people it's easy with a 965 when we're all working with 920s is kind of pompous. We have to do much more work to get the clocks you just multi to get easily.

This screen sucks because Coretemp doesn't show the correct BCLK. I seriously did the test at 4.5ghz. Coretemp is to show idle temps are not a problem.

 

[J-Man]

When are the 8 core CPU's out?

 

[Fitseries3]

hey now binge.... dont murder giorgos th. he may have a 965 but he does know OCing better than us. alot can be learned from him if he's willing to let it out. A LOT of guys keep this kinda info to themselves. hence my problems on XS. NO ONE wants to cough up the details on how they got to where they are. i ask and never even get acknowledged.

it's all good guys.

i dont like how the 965 guys think the 920 is cake like the 965 though. not talking about anyone in particular though.

 

[Fitseries3]

When are the 8 core CPU's out?

mid next year. thats what im getting eventually.

 

[Fitseries3]

now this is how you cool an i7 rig....

 

[Fitseries3]

31c idle all 4 cores at 4.2ghz~!

 

[Fitseries3]

working better...

 

[Binge]

working better...

Much! I want to see you break 26k like I know you can. Good luck!

 

[Chicken Patty]

funny thing is fits cards are on stock coolers, imagine them on LN2!!!!

 

[mojom@n]

working better...

So is the 7 month old version better then Microsoft.Windows.7 Build.6801?

 

[Fitseries3]

yes.

its the only one that allows physx + ati cards.

 

[Fitseries3]

VICTORY IS MINE!!!!

2ghz mems on i7/x58!

Fit's I keep seeing you want to go under the -0c with phase or LN2...

How hard do you think it would be for a NooB to maintain a system..I have the chance to get a SS but dont want any hassle maintaining it(no HVAC experience)

I know I'm not fit but he might agree with me. If you were to go phase you probably won't be doing it 24/7 because of the cost of electricity. Undoing a phase is just as time consuming and difficult as putting it on.. The HVAC parts of owning one you can always talk to your local heating/cooling guy about, but there's a lot more to phase than just maintenance.

With that I go to sleeps... zzZZzzZZzzzz

Thanks!! but this will be only for the odd bench and when I get money together for an i7 rig....
I'm sure with a bit of help I can maintain it but you never know...

EDIT: How many guy's here do have Xtreme cooling??/

 

[LiveOrDie]

i get my i7 in two weeks ill let you know how i go with my oc

Want to get mine in the new year but would like to know if a SS cooler be worth the hassle over water cooling.

The SS will be a gift so the cost does not come into it..but just fun!! what would you go with??

If SS is free, then by all means, take it.

oh yeah buddy....it`s much easier....that`s why i bought the 965...
i will send you my setup and see if you`ll get the same numbers...
nevermind.....story ends here for me....good luck with your effort...
