P5N32-E SLI 680i Quad Failure - Page 7

post #61 of 199
Just some info for GP..your cpu should have no problem being stable over 400mhz..but your mobo might not be so stable. That is just what the GTL mod is supposed to help with. I can tell you* that at 430mhz, my Q6600 is very stable and happy to do whatever..prime95 small FTT's..orthos blend [thanks to Audi for recommending orthos!] while running 12mil SuperPi...at 3.2 its a little different though.

While I have managed a quick boot at 3.6ghz on my new mobo..it was not stable. More testing is to come for sure. I will post any results of successful OC's beyond 3.2ghz with my Q4...
*my sig'd rig is at the work though..so testing time has been very limited since it has been up and running. Also, its my 1st set of HZ's and I am still 'learning' them...

just set them to 2.3V and try getting close to 950MHz with 4-4-4-12-1T which is what gave me the lowest SuperPi times... the high end for speed was 4-4-4-12-2T 1100MHz... I havent OC'ed them back up isnce a chrash from not testing for stability after I flashed to 1103, but I have been running 4-4-4-12-2t 1000MHz just fine with 4 sticks... now that I got proper NB cooling I should try and up it all the way, but first I have to get an OC'ing install on a separate HDD...

I guess I better get that install ready if I will get serious about this mod... I mean, I could finally break my stupid 450FSB steel wall of China... one I couldn't jump either... that guy got 470 3.73GHz out of an E6300!!!! (and look at my sig!!!)

I'd be happy with an uber-stable 3.4GHz... Reeeal happy!!!!

then I might be able to preview 1080p in my 32-bit NLE flawlessly which might make me reconsider buying into the Q6600 G0 and waiting for the natives... but that will be hard to pass up... regardless if I am going to stick with this board I need to look into this mod hard... cause I don't want to be stuck at 3.15GHz with my E6300 and most definitely don't want to be stuck at 3.0GHz with a $300 Quad that is known for doing 3.4 EASY!

Now you have a P35 P5k in your sig... is that what you are considering this mod for?

Frankly, i dont think the P5K needs the GTLv mod...I am already at 430mhz with my Q6600..the mobo is teriffic! I have already been to 450mhz..but not stable. My goal is to have a 500mhz FSB for the Q4..6x or 7x multi...hopefully 7x as that should be ~3.5ghz.

Thanks for that tidbit..I have the HZ's running 1000mhz at 4-4-4-12-4-20-8-9-9-9 on 2.3v currently...I think I will stay around there..i dont know if there will be too much benefit to pushing them much faster.

I had 338 with my QX6800 running benches

and heres at 345

I was using the multi more for the higher OC than the FSB though.

I would be leery of modding my mobo, especially if I need a soldiering iron. One thing I have learned in OCing is: sweet spot. Sweet spot for vcore, fsb, ram timings, nb volts, sb volts, you name it, it needs a sweet spot. That means countless of hours, rebooting and writing notes.

Until I have all of my Quads+mobo+rams perfect sweet spots then I might use the vdroop mod. Even after the mod, you have to still find a NEW sweet spot.

The mod this thread is about is focused at FSB's over 400mhz, when using a 680i mobo and a Q4 cpu. The 680i doesnt have enough GLTv for the cpu to operate well at the higher FSB. Without this mod..you would need a new mobo to successfully achieve those clocks.

While soldering the mobo isnt for eveyone, it is not that difficult to do, and really is needed to stabilize extreme clock speeds, by adding much needed MCHv, PLLv and even extra SBv. Most RAM and vcore options are good enough to get some really high speeds..but BIOS options are pretty limited to the amount of voltage for the mobo components itself...

BTW, the vdroop mod works killer! It will help stabilize your OC and get rid of unnecessary vcore, as you can set the cpu for the voltage you want it to receive..and you dont get .04-.07v less...more like .01v less. I have mod'd for vdroop on my P5B-dlx and my P5K..working great!

so that gets rid of high voltsges during idle? that sounds like a good time/effort investment then... hummm.... linky??

there i practicaly none... tht's why I have slacked on OC'ing them all the way back up... maybe I'll try your complete timings as I have everything else on auto...

why did you get different RAM? are you going to run all four sticks together?
