Floored the volts to my NB...... (1.85v)

**kris23** · Nov 15, 2009, 07:59 PM

well....... in my quest for the most performance outta my system....... i successfully floored the volts of my NB on the Asus Maximus Formula to the max setting of 1.85v....... i have been able to finally boot into windows with my CPU at 3.8GHz+

im really expecting this thing to explode now but my NB temps are actually really low! (40C) probably because i have a high CFM fan going on top of it...... even feeling the heatsink is barely warm to the touch

now...... for my question.... who thinks im crazy? and why?

also, for the more experienced OCers, are there any other risks other than overheating that i have to be wary of with volts this high?

**kris23** · Nov 15, 2009, 08:07 PM

aww lame..... right after i posted this... my system crashed.....

got it back up running its normal OC though.....

[hobo]eclipse · Nov 15, 2009, 09:22 PM

really not surprized on the crash, that is a lot of nb voltage there. i dont believe your doing any good with it that high, not sure about damage. i am not familiar with your board or the x38 ne more, but what options are available for voltage to the cpu pll (clock gen) cpu termination and wat/ how many reference voltages are on there? have u read up much about the reference voltages and ever googled "edge of stability". quite technical read but may help. also be sure about your RAM timings.

It knew you were bragging about it..... showoff!

**kris23** · Nov 15, 2009, 09:43 PM

haha well after doing some reading with the info [hobo]eclipse gave me and a couple of other places, i found that my OC is inline with other Maximus Formula users with people using Gigabyte X38s scoring a bit higher.....

i already had plenty high volts on the CPU PLL and FSB termination..... i guess i just gotta give up on this one! not worth the added stress....

[hobo]eclipse · Nov 15, 2009, 09:54 PM

yas i never played with a quad on the x38 (btw finally updated specs under name), but i recall the NB difference. if your getting reboot while at near idle states (web surfing, music movie playback) for me ne way, it is a sure sign to mess with the voltage references. i have oc profile saved that is 10 hrs blend stable, 10 hrs 16 pass memtest stable, and with extensive l4d testing, but will reboot itself while web surfing. lol, tuning in the references currently.

**kris23** · Nov 15, 2009, 10:22 PM

i bet i could easily get 4GHz if i had a P45 chipset.... used a P45 board in a system i sold my friend an Asus P5E...... that thing outdid my maximus formula in terms of FSB and its a mainstream board....

[hobo]eclipse · Nov 15, 2009, 10:35 PM

o im on my way here, it not something to expect real easy real quick. if i wanna know just how things are reacting to different settings, its gunna take time and observation.

Booted a few times quite awhile back a 550+ FSB, that needed some voltage, but this here is running 1.2-1.22 MCH.

your CPU is an E0 revision wasnt it? wat voltage u use to the CPU for 3.6?

**kris23** · Nov 15, 2009, 10:39 PM

volts are 1.168v from CPU-Z current OC is 3.65GHz

but i set it to 1.2V in BIOS. not really sure which one to believe...... even the in-BIOS hardware monitor shows 1.168v......

[hobo]eclipse · Nov 15, 2009, 11:24 PM

nice! i believe i was around 1.25 for the 3.6 range with this C1. i didnt catch the 4x2GB mem config earlier, no wonder the x38 is askin for the juice! lol. no doubt you want the 8 gig, but may be fun to see how it reacts to 2x2. u know. the x38 will do the fsb, the wolfy i had was at 471 on the x38, but being a dual twas easy. i bet u get closer to 450 fsb with 2 sticks.

about your voltage to cpu, does it droop further than 1.168 at load? like p95. in my experience with this board the higher i go from a stock cpu voltage the bigger the droop is. with this giga board set to 1.35 cpu voltage it would idle right around 1.296/1.3 but droop to 1.26 at p95 load, but i use the load line calibration with keeps the cpu voltage at 1.328 at idle and load while set at 1.35 in bios.

**kris23** · Nov 15, 2009, 11:55 PM

yea there was definitely a vdroop..... i cant remember by how much but there was a pretty big one..... ill stress it later, just going to find the minimuim stable volts for my mobo

i use the intel Burn Test to test my system... makes things visible quicker...

i just upped my vCore to 1.3v just since i dont see a temp difference at idle or load with my cooling.... seen as 1.264v

[hobo]eclipse · Nov 16, 2009, 12:02 AM

carefull with that intel bt, im sure u know, but the cpu amp and wattage draw is quite abit more with oc'ing on these quads. i guess its my board that that has the sensor, but in everest i get a amp\watts reading for cpu, with a p95 its max 80-90 amp/125watt draw. with ibt its no problem to get to 100 amp 150 watt draw. ive also read alil about people opions that it may damage mobo cpu pwr vrm. plus with my 1300 rpm noctual lets it heat quite abit.

if b4 wen it rebooted after the initial post u were at 1.2 cpu v, i would consider that a good possibilty of causing the reboot. im not sure how much of an effect the 4x2 RAM setup will effect the voltage needed to cpu, but i'd imagine it would have some.

**kris23** · Nov 16, 2009, 01:23 AM

yea with my OC, i see around 70A as reported by CPUID HWmonitor doesnt go to far out of the processor's normal TDP

im testing right now and i see 71.18A 82.23W Vcore volts under load is 1.216v

isaak · Nov 16, 2009, 06:38 AM

My CPU is crazy like that, requires 1.2vcore to get 3.2ghz, and I have to up it to 1.3vcore to get stable at 3.4ghz, which is when the temps get too high... (for my liking - 64C max)

anyone have any suggestions as to why?

while i do not know the ins and outs of your setup, it is common for chips to have a "wall" if you will. a point where the voltage increase was negligible b4 but now requires more juice to get to the good stuff

Especially when your upping the FSB. Whats that your running for RAM? 2x2gb and 2x1gb? i don't think that will help you achieve higher clocks, and may hinder the possibility.

I can pretty much guarantee that. I too had the Formula and I could not break 3.8GHz no matter what the hell I tried. I pulled it out, dropped in a $80 P45 and I can now run at over 4.3GHz with lower voltages/temps! If you are serious about oc'ing a 775 you need a P45!

[hobo]eclipse · Nov 22, 2009, 05:11 PM

nice specs there dip, you are running an e0 revision? or no?

do you use easy tune 6? can ya post a screenshot for a lil comparison? iv'e got a C1 chip with a pack date of 04/02/09 so its a late one. it doesnt do to bad but maybe about at my current limit as the 1300 RPM noctua i have is not cutting it at full load. also i got have the LLC on and the vcore doesnt move, how do feel about LLC, you use it?

dipstick · Nov 22, 2009, 06:30 PM

Thanks, I think all 9650's are e0. I don't use the software tho, all done through the bios. These are my settings but there is a also a yorkfield thread here that makes for a good read. And yes, I do like to enable LLC on most boards I have seen. The drop is too much without it
