can somebody write down the max voltages that should be used for the settings in bios? i just want to make sure that i don't go over them and really screw something up... thanks!

[froste]

Hey guys, new to the forums here. I got my board last saturday. Been working on some OC's off and on. So far I like the board, I have an issue where it wont POST on some restarts with stable OC settings in the latest BIOS. Hopefully this gets addressed in a future BIOS. Below are some shots of the work in progress. For daily use I run 3.8GHz 423x9 w/ memory at 1:1. Voltages are (as shown by ASUS PC Probe) CPU: 1.51v, FSBT: 1.50; NB: 1.65. My PLL voltage is at 1.76 in BIOS and Load line calibration is on. Currently using 0505 BIOS.

froste what is your room temp??

[Wiggy McShades]

can someone explain what the cpu ppl voltage does?

[CERO]

Does this board "hates" Samsung Drives like the P5K premium?

CPU pll is the part of cpu that runs FSB, so to speak. So, as you increase FSB, this voltage may need an increase in order for the cpu to continue functioning @ the overclocked FSB speeds.

Quads need more cpu pll than duals, from my experience, however the dualies I got all do 450 or higher without increase to CPU PLL. the one that stops @ 450 requires more voltage to go higher, and adjustment of this voltage allowed 25mhz FSB from stock, on a previous board that only offered a max of 1.7v for CPU PLL volts. I have not had a chance to throw that cpu in here yet.

The other cpu does 515mhz FSB with 1.5v CPU PLL, So i have yet to find a need to increase this voltage with this cpu yet.

I have not be able to determine if this truly is FSB-related or raw MHZ-related, but I'll be investigating this with this maxumus as it allows beter control of voltges than any other board I've got now.

ahh ive never seen this on a board before this asus. also are the gtl voltages on this wierd or is it just me the 680i i had needed fine tweaking or else it was not stable AT ALL, where this has only like 5 choices for gtl voltages and its fine despite it seemingly beeing a very broad setting

[cadaveca]

GTL is like inter-FSB communication votlage...voltage for core-core communication. AS the FSB is the bus used for this communication, CPU PLL has a similar effect as well, however you'll find that GTL tweaking only really shows signifigant gains for quadcores, and not duals, as the source for each of the operation's votlages(GTL, CPU PLL) are related, but not the same.

GTL is liek the "low" setting to "HIGH" setting voltages for communication, "low" being like a "0", and "HIGH" being a "1". these ride within the FSB voltage, but FSB is bus for cpu-chipset, and each provides it's own power source for out-bound communication, so each must be tweaked individually, as each will have a differing load on them, based on what work is being done. The GTL voltage will drop as it gets to each core, a little bit, and when you increase speeds, this drop is larger, so we adjust GTL to compensate for this. A board with lots of expansion cards and 4 DIMMs is more likely to need chipset FSB volts than CPU FSB volts, due to the load on the chipset, while on a board with jsut a vidcard and two DIMMs, it's not going to be as important.

SAme for the cpu..quad is more work than dual, and high FSB is more work as well...so hopefully by now you kinda understand what's going on with these settings.

yeah im pretty familiar with the gtl voltage tweaking having gone through two dfi's with my quad, but it just seems like this asus board has a more broad way of adjusting these settings than most other boards. i know the dfi and the newest abit's all adjust it point by point and per core. i guess its a good thing, what took me days of finding stability on my dfi took me maybe 20 minutes on this asus. so im just kinda curious as to how asus is doing this. maybe a table that is in relation to the vtt? as i know the vtt and the gtl voltages to have a pretty direct relation

worked with a maxtor and a wd for me, i dont think this has any hard drive compatibility issues

I dunno. It could just be a standard formula..as "A" increase "X" amount, "B" must increase proprtionally to "X". This would allow good clocking, but not the fine-tuning that you're looking for. I think maybe the "EPU" is what does it, as this board installs driver for such, so I imagine that this driver may adjust GTL as FSB voltages as needed, again, based on a set formula. I cannot fathom any other reason for ASUS to highlight this "EPU" othr than for what I mentioned, as Intel cpu's have thier own power-state management, so I assume that the "EPU" deals with both cpu and chipset.

froste what is your room temp??

The 3Dmark and super Pi runs were last night, I am not sure exact temp. Proabably 75 Fahrenheit in my room or around there.

Bit of a question here guys...

I just received my Maximus Formula from a certain UK online store...

Well they sent me the wrong one. I ordered the Non SE version, as I won't be water cooling. They sent me the SE version with the Fusion Block. My luck. Next day delivery was 3 days late from them too, and then it's the wrong board, even though my invoice clearly states the Non SE version.

Now, my question is, will my n/b suffer with the Fusion Block over the aircooled version? If not I'll probably just keep the board to save the hassle, but if for an aircooled rig, the normal aircooled block is better, I'll be returning this board (at their expense) and getting the correct version!

Please help me out here guys, I've spent half a week waiting for this board, booked the weekend off work to rebuild and play with my new system, and at every possible opportunity something has gone wrong!

[froste]

I have the SE version and only water cool my CPU, NB runs cool even when overclocking. I say keep the SE in case you get the water cooling bug down the road.

[kup]

I may one day water cool, but right now I'm more interested in how it'll affect my temps and overclocks using the water block as an air cooler? What do you reckon?

[GAR]

i have the SE, and my NB runs about 15c cooler, than it did on my gigabyte X38, the fuzion block is also a good air cooler as well, i would def. keep the SE!

I agree. +1

Hey got this board, after buying Asus P5N32 SLI and finding I couldn't clock the q6600 on it to any degree.

After reading that there is a vdroop mod out there that it seems only EVGA boards seemed to have been factory done.

So i bought this board, and what can I say its the easiest board i ever worked with regarding clocking. All I had to do was to first install the next bios up as i had strange results from cpuz. The mutiplier was fluctuating from 9 to 6.

Upgraded to 504 and at once fixed the fluctuation.

All I had to do then was set q6850 in bios to get 3000mhz speed, but putting it on crazy setting got 3.700mhz without touching a single volt. The only probs ican see is the NB can get a little warmer. So am going to watercool with XSPC kit, but the great thing was it is very stable. Have not had a single crash. (maybe im lucky but I dont think so this board ROCKs)

I just thought N00bs like me to overclocking, would like to hear that quad core processors on this board can be overclocked easily and with 4GB of memory on board. To a high speed 4ghz easlily achievable. Whereas the P5N32 struggled to get 3Ghz.

q6600, 3ghz present 3.7Ghz air but will watercool, 4GB Crucial PC8500 running at 1066mhz, 2 Quantum Raptors, 1 Spinpoint, Adaptec 39160, 4*15K Atlas II, BFG8800GTX, tj09 Silverstone, Enermax Galaxy and Dell 30"3007-HC XP+Vista64 Dual Boot

Are you actively cooling the Fuzion Block? Or just using it empty (no water) without any active cooling (aside from the 900 side fan?)?

[TheSamurai]

i'm WC'ing my cpu and eventually my gpu. i'm not going to bother with the fusion block right now. like everybody said, it's quite cool without with the water cooling!!!

[GAR]

the only thing cooling the NB is my side fan on the 900, thats its.......and i can put my finger on it for more than 20 seconds, i could not do this with the gigabyte, my finger would burn up.

[Talonman]

Man, if you can put your finger on the NB on air, for 20 sec or so, the stock Fusion cooling on water aught to be more than enouigh....

Thanks for the info.

1 more reason to love the board, and I havent even turned the key over yet...

This is the best board i have ever owned, and i have owned them all, from the 965, 975, to p35 and 680i, this is my fav.

[GAR]

Anyone ever catch this, prime 95 isnt stressing my cpu 100%.....system is always 12-25% using the cpu....anyone else have this issue? vista x64 here.

[Darkatom]

Anyone know if a thermalright HR05-IFX (withfan) on the NB and a evercool cooler (http://www.newegg.com/Product/Produc...82E16835119080) on the SB will fit ok ? If so are they sufficient to keep things cooler than the stock heatsink ?
