The Maximus Formula Thread - Help/OCing/Guide/Rampage conversion

[zlojack]

I still see no compelling reason to update from 0308 to 0401.

1. The most important difference between the two is tRD or Performance Level. This is implicitly controlled in the MF BIOS through the transaction booster, but the RF not only gives direct control over this, but can allow phase "pull-ins", which basically allow you to run different RAM/FSB phases at the nominated performance level minus one. Using this added feature, many of us are able to run our RAM near DDR3 SPEEDS. A very in-depth article explains the brute power of this additional flexibility. It begins on this page: AnandTech Article. It is recommended reading even if you don't flash Rampage because it really goes into fabulous detail about NB, RAM, and FSB. Everything you wanted to know but were afraid to ask, basically.

2. There's a good thread about the P5E HERE. It has BIOS information.

3. I'm not following this question, sorry.

Thanks ill check out the links, i have been out of the loop for a while, even got the x38 cause of the rocketraid 3520 and 4 wd640gb not cause crossfire

I believe he is asking if you pencil mod for Vdroop, what is the measured resistance with a multimeter across the resistor....I wondered this myself when I read the first post...I find load line calibration enabled adequate myself, but when you do pencil mods it's nice to know target resistance so you don't over do it.

Yap, exacly what im asking, i would like to know the final resistance before i assemble everything, dont have the space to test it out of the case.

With loadline, what kind of a vdoop do you get?

[aicjofs]

For loadline enabled I get this on 2 different boards

qx6700 at 3.8-3.6Ghz on Maximus around .01

qx9650 at 4.5Ghz on Maximus SE around .02 to .025, which is a little more then I like normally, however since the 45nm is less tolerant of voltage I don't mind a little droop to prevent overshoot returning from load to idle.

[aussie-revhead]

Im currently priming at 3200 just to find a nice stable 24/7 clock with low volts . With loadline enabled and vcore set to 1.25v in bios , cpu-z is showing 1.232v loaded , so thats pretty decent . Next time Im running at max overclock I will check again though I think it drops a little more at higher voltages.

[Brama]

Anyone knows what is the maximum safe temp for the x38/x48 ?

Following Intel datasheets, X38 has a max of 92° and X48 of 85°.

They are absolute max values.

I think till 60-65° 24/7 it is safe to operate.

thanks guys, i might not even bother with the mod then, on the ga p35-ds3p i got now i get 1.248 on idle and 1.216 on small fft load, so at least asus doesnt seem worse than that if not better at least, thaught it had a bigger drop than that.

[HDPC]

Reaching out for help.

I tried some of the templates on the first post, but I can't get mine to OC at all. It kept saying OC failed (something like that). Please forgive me, as I am still learning all this.

I made all the changes, but when I go to the CPU advanced Configuration, my CPU information never changes. It always shows 2.4GHz.

Can anyone help me? Anyone with similiar hardware can post there settings? Thanks.

I must find some way of cooling my Rampage without removing que stock cooling

With 1,51v on the x48 I get 55ºC in full. Having a room temperature of 19ºC this is bad as the summer is comig soon

[Dostoyevsky77]

Dostoyevsky, that bandwidth is sick!

Is that on 24/7 settings?

What PL and what Pull-Ins are you using for that?

Hehe, thanks. But there's a lot more to it than just PL and pull-ins. It is my 24/7, and I stole most of what I know from Zucker and Grnfinger. A really high FSB in the 333 strap for 8:6 seems like the sweet spot with my RAM (and maybe the board???). I run at PL7 with no pull-ins. Pulling in phases 4 and 5 can POST, but not OS. Of course, the Ballistix are good even though it's not on the Crucial QVL. Some people have problems, but I've had nothing but success.

@ Millyons, sorry I don't know the answer to your question about the voltage. I really hope you read that article, though. It might convince you that the Rampage BIOS is worth flashing to. Once you have a USB drive dedicated to flashing BIOS, it becomes infinitely simple to flash to a new RF BIOS or flash back to MF BIOS. Honestly, it's almost as easy as EZFlash! Oh, and by the way, my sister lives in Beograde. She teaches English at a uni there; not sure which one.

[zlojack]

Hmm...

Well I can't run that FSB on my quad. I've got 421 FSB with 561 RAM

I'm on the 400 strap tRD 6 and tRFC 60 all pullins disabled with 8GB. I'm still pretty happy with my bandwidth, but yours is awesome!

I'm going to play a bit with my subtimings and see if I can squeeze a little more out of these awesome Corsair sticks.

For real world performance, the 1:1 w/ @ cl4 is a bit better then cl5 at only 1066, now if @ 1200 @ cl5 as in 5-5-5-18, then you'll see big difference in acores as wel as performance. If at 400FSB airm for 1200 (3:2) or close to it. You will need 2.24v for over 1175MHz if relaxing trd to 50~55.


My 1st guess will be too much stressing on DRAM performance boosting and tigh timings. 2md is as the guys above mentioned, except if he was reffering to actual voltages, some more then needed, and a few not enough.

Try.. more vcore, few Q6600's need up to 1.58~1.6v, PLL: of at least 1.632v but up to 1.712, FSBT of 1.42v~ but as much as 1.48v (1.504v on the 8x), NB shouldnt need more then 1.504 at such a mild FSB of only 400, but6 if on a divider. SB: 1.05~1.075v, SB_1.5: 1.5~1.55v and PCIE to 110 for starters.

This is an average starting point. Just remeber to keep RAM out of it as much as possable till you know it's stable. You're just gonna end up crashing it so often and corrupt your OS install.

Just take it one step at a time. All voltages as actual reported.

1200mhz produces much better at 5-5-5-14 for me.

Thanks Grn

Thank You, started with your suggested settings, ran prime for 2 hrs, everything good. bumped vcore & n/b volt down two notches, so far so good, will let prime overnight, maybe lower a little more if still stable.

would be nice to get ram back to 1066 or better, with 333 strap only have option of 960 or 1280, running at 960 now, 1280 is to much for my ram I think, will have to play with it after I'm sure that I'm stable at lowest possible voltages

I use the 400 strap to get 1066mhz

[Spyrus]

Since 0401 has loosen tREF to 3120 instead of 16383 memory latency will be loose also
and also bandwidth but no as much.
Sure will make more modules compatible since is jedec compatible (7.5-15us for tref => ~1600T-3120T)
I think i will go back to 0219 or 0308, since my ram have no problem with that.
At this time i have Linux and not windows on main rig so i have not seen how much is the difference.

[Krav]

My 3.3 q6600 passes 24 hour blend prime which i tested a month ago, but recently i guess due to weather not sure in game ive got bsod twice.

I didnt think weather could affect my stability so much. I think its the northbridge which is getting to hot and already got a spotcool fan pointed at it.

Im on bios 907 at the mo will i see any better stability or lower temps with one of the newer bios's?

Thanks.

[cadaveca]

the lowered Tref and other timings in 1201 helped lower chipset voltages quite a bit. otherwise...they are all basically the same.

Thanks, i still didnt get a chance but will soon, the usb flash is not a problem, have one set up for couple years now with all my bioses, i think i still might have the afudos i used on the p5b dlx on it

thats nice, how does she like it here?

[Nuker_]

How do you make slash or backslash in DOS then? Alt gr does not work and all combinations differ from the ones I'm used to. Maybe that should be included in this guide?

[kup]

I just type a forward slash or a backslash and it works?

On my keyboard I have to type shift + 7 or + + alt gr to get slashes. I don't have any special keys to do so. I found out that alt + 92 can make a slash, but it is the wrong type...

[kup]

You don't have the forward and backslash keys?

[Grnfinger]

wtf kind of keyboard do you have?

"/" is the same key as the "?" key
"\" is the same key as the "|" (pipe) key above the enterkey or below shift key on the right, depending on what modle keyboard you have

[XtremeTiramisu]

MF 1201 and RF0401 are the best bioses released up-to-date for me.
In previous MF or RF bioses, I'd get occassional DET RAM hang whether my system is stable or not.
I've just finished 2 days testings with diff config with both MF1201 and RF0401 and I've NEVER come accross with DET RAM hang ever.
It doesn't matter whether my OC'ed settings were Prime/OCCT stable or not, the system hasn't encountered any DET RAM hang issue yet.
The stability is greatly improved from either bios.

Isn`t it P45!? Or did you make a joke? XS.de would be great
