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

[jwfitt]

jwfitt,
Are you still prime95 blend stable? I don't think this is a matter of voltages.
Rather, our lovely blue G.Skill 8500's are requiring some rather particular memory timing settings.
Time to dive in!

I was around 1.375 cpu vcore, and auto ram timings. Right now, it's looking pretty good for 9.5x400, 333 strap, 801 Ram with manual timings at 4-4-4-12, and 55 trfc, twister:moderate, booster:disabled @ 3 (gonna try to bring to 0). Same everything else as my previous post...well over an hour now, gonna let it run while i go sleep!

Which is better performance wise:
445*8 = 3560MHz with DDR2 @ 1066MHz giving you a 12:10 ratio.
OR
400*9 = 3600MHz with DDR2 @ 1066MHz giving you a 16:12 ratio

Shouldn't you be able to reduce cpuv going from 9 multi to an 8?

[initialised]

Thanks for that. My Maximus is now a Rampage. Slick mod, but could you put a link to the latest 219? BIOS and to the Asus Rampage downloads page on the first post?

I would think the 8 multi would do slightly better, but you'd have to bench it to be sure.
Another option is 450x8 3600MHz @ 1080MHz and that with the right timing is no a bad setup, or wasnt for me anyways when I still had my Q6600

I have read in some reviews about 3870 cards not working in maximus motherboard. Was going to buy a Diamond 3870 512mb DDR4 512mb anyone every heard of this problem.

No problem at all. I had the Diamond HD3870 512 and it ran perfect, now I have the Diamond HD3870X2 1G and it runs prefect.

Sorry if this has been asked before, but is it better to flash this board to the Rampage Formula BIOS, or the latest Maximus Formula beta BIOS? I have a board coming, and I want to get it set right the first time. I know the Rampage BIOS is a little dated compared to the Formula one, but I'm not sure if they've increased the FSB capability with the Formula one or not. Last I heard the Rampage one was getting higher FSB on peoples boards. Thanks

I am setting mine up this weekend and I am certainly going to use the latest Asus bios that is specific to this board. If it doesn't do what I want it to then I will perhaps flash to the Rampage bios. Not sure if I would want to void my warranty in hopes of better performance or sell it and buy something different.

Ive overclocked my q6600 to 3.3 and running prime95 my temps are good for cpu but my northbridge is reaching 55 sometimes, it idles at 48 which is same as what it was on my 3ghz setting.

My southbridge is running at 49-50 on full load.

Am i looking at trouble down the road if its running at these temps?

Also my cpu voltage is 1.30volts but as soon as i run prime 95 it drops to 1.26 s this normal?

[dimsdale]

What do you folks make of this "Write Recovery Time" (tWR) setting in the BIOS? According to the BIOS, it likes the default to be 6.
Now looking at the EPP for my G.Skills 8500s in Everest, it seems to be saying that this Write Recovery Time (tWR) should be set for 13!

I've looked at a lot of people's settings, and I've never seen anyone post a tWR that high. Does 13 make any sense?

What is your NB voltage? You might not need it as high as you have it. Try dropping it in .1 increments and see if you can maintain stability.

Do you have Load Line Calibration enabled?

[MrHydes]

no way back turn this difficult choice ...serious thought at least.. double
the good things are so much better than the new bios available?

The Stilt thanks for this tutorial very nice, very sharp
congratulations, fabulous job for the comunity.

my NB voltage is at 1.31 in bios = 1.36 ( real ) i had it at 1.33 (real) and lost stability

I should say i have the SE version but not using watercooling on the NB also.

Do you have Load Line Calibration enabled?

Nope guess i should give that a bash then? Ive been purposely setting my voltages in the bios at higher volts due to the overvolt thing does this make the bios values same as the real values?

page 13 tells you how to go back.

Would be great to have the OP updated with the latest info so people can stop asking the same questions over and over again. It'll also make it easier to search for information.

Loadline Calibration will make the BIOS voltage and actual voltage much closer when the CPU is under load. It's generally helpful for overclocking as you won't have to have your CPU jacked up with extra volts at idle just so that you have enough after the drop that takes place with load.

Google on maximus formula and "vdroop". Or just search this thread!

[ZenEffect]

yes it would be nice, but i imagine the stilt has alot of other stuff going on atm

perhaps someone (not me, im lazy) should start a part2 as kup has done on the maximus

[GlowingBulb]

Or perhaps people should read through the thread as there's a lot of good info in there. I know it's a long thread but it saves asking the same question that must have been asked many times before. Took me the best part of a month to read the 1st Maximus Formula thread but I found the answers to a lot of what I wanted to know in there. I was also able to see the results of each of the BIOS releases before I decided whether to upgrade or not.

very true, those people interested in the mod SHOULD read through all the pages to gather as much info as they can, all i was stating was that the basic information could be consolidated into a really useful guide

kk thanks for help

[Nuckin_Futs]

O.K. I tested since last night by Disabling ACPI 2.0 and repost of VGA was already off too and as I stated, I alwayz use S3 only, and of corse ACPI suprt On. 3 time of S3/STR and out again and so far, so good. On day 2, yet it was a warm morning here in California.

Also, to the guy about BIOS overvolting. You already know this mobo overvolts just about all the settings. so you need to set as LESSER value to get what you might want in actual as reported and used and not go to high. That is why it makes sence to POST here with actual or as reported by CMOS, not as set. It is simple, set a voltage, then reboot entering CMOS to read it in Power management. Just like that. And these should be the only voltages we need to see in POST since each mobo will overvolt a tad different and especially in a combo of variuos PLL and GTL settings as well as FSB level.

[TheScavenger]

Loadline Calibration is definitely a must. Without it enabled my voltages were all over the place and my system was really unstable.

That HD 3870 compatability nonsense mentioned above is silly.
