ASUS Maximus Formula SE

[ReaperX]

Hello...

I have 4x1gb ballistix tracer 1066 on maximus with 0903 bios and Vista x64 installed.

I tried most of the settings posted in the thread but I'm having big problem with ram overclocking..(Anything other than stock ram speed results in memtest errors or os bsod).


Any help would be appreciated...

Did you read any of my previous post? They all point to overclocking challanges when running 4 slots and overclocking at the same time. I and many serious overclockers since the birth of DDR have never fussed with overclocking 4 slots occupied. It put a major address load on the memory controller and is really only a bennifit for servers, not overclockers. 2 gb of RAM in 2 slots has prooven to be the most reliable for several years now. even dence RAM of 2gb x 2 is adding a challange.

You can do it but you now need to do a lot of relaxing and upping on some mobo volts.

For starters, try this. Keep strap and frequency to AUTO (1:1), up PCI-E to 111, open timings close to stock (usually 5-5-5-18 for 1066), Enable Static Read Control if using or wanting higher FSB, Disable DRAM Booster and relax to 3~5, set Ai Clock Twister to light. Up CPU GTL Ref to 63x, and chipset GTL Ref to 67x, FSBT to 1.47~1.50v, and NB to at least 1.5v~1.52v for the 450~485FSB range. Although, the 4 slot configuration is a compromise of a bit of less FSB on top of looser timings and yet a lil added mobo volts.

This should get you to Prime further. Scores will report a tad less on paper but you may never notice if you didnt see the numbers.

Let me know how it works

I was running 4 x 1 GB sticks of two different brands, two Corsair TWIN2X2048-8500C5 and two Crucial Ballistix BL2KIT12864AA1065. They were both DDR-1066 and I ran them at 5-5-5-15 @ 2.2 V.

Currently I am running 8 GB of RAM, 4 x 2 GB of OCZ OCZ2N800SR4GK (DDR-6400 running at DDR-1066). I couldn't run these at their specified rating of 5-4-4-15 without tweaking the northbridge and DRAM voltage.

With my 4 x 1 GB setup, I had northbridge at 1.39 V and DRAM at 2.2 V. With the 4 x 2 GB setup, I had to increase the northbridge to 1.55 V and DRAM was fine at 2.2 V (2.12 V in the BIOS, but the board overvolts).

The OCZ were finicky. I couldn't get them running when manually setting the 5-4-4-15 timings and I had to set them to auto. After testing over the weekend, I found that some of the sub-timings had EPP values higher than what I could manually set in the BIOS.

I hope that helps, good luck with the overclocking.
