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

[Zucker2k]

This is definitely going to get some of you folks to sit up and mess around a little bit more in your various bios setups. It was simple, really. I just selected 266 strap and left everything else at it is lowest setting. Only settings I touched were vcore and vdimm.

Setup:

Rampage Formula, Bios 0308, Performance Level 7
Q9450 @ 8x450, 1.160v
2x2GB G.Skill PC2 8500 (DDR2 1066) @ 1125MHZ, 1.97v

Check out these insane voltages...

I know back in the day. The 939 day that is. It was a big strain on your MB to run 4 memory sticks vs 2. With the Intel X38 is that still a problem? Should I be going for 2X2GB vs 4X1GB>

You can go for 2x 2GB but choose carefully, there's still issues and needs some tweaking to run stable at higher clocks....

I recommend G-SKill or OCZ

Ok I think now might be a good time to flash to a rampage!

Nice work!

zucker2k - can you manage to get to a pl6? or ai clock twister to strong or stronger?
with 0461 bios i'm at 455x8, fsb strap 266 and ram 1137 and ai clock twiester moderate. as soon as i try pl6 or ai clock twister to strong or stronger, the mobo won't post, hang on "det dram", so i'm wondering if 0308 bios is more friendly with low pl...

no you wont get PL6 with that FSB and divider. PL7 will be the best you can do without a hang.

Always impressive as usual
Your running a real Rampage correct not a Maximus modded board?

Thanks, yep, running a rampage here. By the way, I'm on the 333 strap now, 3.7Ghz and working upwards.

why do u guys prefer bios 308 then latest one?

308 gives the best bandwidth/stability atm
Better tref value of 16383

[icecpu]

Can someone tell me what is the northbridge voltage range for a quad core ??
I'm planning to get Q9650

[Malik]

I have 1.37V with my qx9650

[Zucker2k]

Hardware same as above on Vista x64

[Grnfinger]

hmm I think its time to grab a 9450 and play
BUT the 9550's will soon be price cut and there a very sweet looking chip.

[Cold Storm]

When do you think the price cut will be? Been waiting on that to happen myself..

Can you please post your complete settings for this 450x8 and ram ar 1200? Are you using PL6?
I'm also trying to get my system stable with ram at 1200, bit core fails after 2-8 min of prime95 blend...tried upping differents voltages, changed mem subtimings, played with gtls, but no way, every time a core fails after few minutes of priming...
thanks

[MarcusFoX]

lol Yes

that is my Stable clock...... I use this 24/7. I use this in COD4 in Cal and Cevo Gaming leagues

Highest ive had the E8400 is 4.8 but it isnt stable.... id like to see some screen shots of some of these xtreme clocks tested with prime for 16 hours I dont think they could last 2 minute, get a heavy overclock is the easy part getting it stable is the the real task.

If anyone has some pointers for this Maximus Formula Rampage editon with a an E8400 bios 403.... feel free to give advice so I can get some higher stable clocks.

[RCG_Bex]

Well since updating to Rampage BIOS 308 from my Maximus 903 I've dropped my CPU V by like 0.18v! Epic when it needed nearly 1.6v before to get anything stable! 266 strap with ram @ 1245mhz

However it does have 1 issue with prime after a while so I need to tweak that out. Might need to slacken the mem timing a wee bit but I think it just needs a wee bit more voltage. Currently @ 5-5-5-18 2T @ 2.2v if I recall (my RAM is sick though, found it can do really stupid OC's at slack timings. I've seen people run it @ 1402mhz with 5-8-8-21 2T with 2.45v

Nice clocks....

The 4.5 at 1.456 volts hasnt been stress tested.

Did you find the 308 bios better than the 403 bios??

I have to run 1.5v or more to get anything stable after 4ghz, and it seems the only difference is the bios version

what you running your trd at GRN and is your board vmod penciled

Torturing your hardware for 16 hours straight at levels you're never ever going to use your system is a little bit e-penis wagging in imho. This is the highest I ever bothered priming.

[RCG_Bex]

Gah! Rampage BIOS sucks balls for me apart from lower voltages. Doesn't like my E6750 clocking to 4ghz at all!

Tried everything I can think of - won't even run my games stable. Although I must say, it's taught me huge ammounts more about my RAM and timings

Might flash back to the Maximus 0903 again.... then again... might leave it and get a new CPU

....although I do really like my E6750 - it's my first OC'ing chip

Opinions?

There was no point in priming 4500 there was little difference from 4400
308 is the best bios to date imo

Post your current Rampage bios setup
Rampage will clock higher than Maximus, it takes awhile to learn and tweak the settings
9x450 should be a easy clock for Rampage

That's all off the top of my head that I've tried... I've papers at home with scribbles with other attempts that Ill post when I get home from wokr (I love my work - click the "microplay" sig to see where I work)

Take the NB volts to 1.53, I needed 1.53 to run at 500 FSB
