DFI LT X48+OCZ reaper problems

[nolifer]

Hey everyone, great forum, lots and lotsa helpful topics.

I'm having stability problems with my ram at 1066MHz.

I'm using the 2x2GB 0cz hpc reaper kit(5-5-5-18 2.1-2.2v) and the newest bios(29/08 I think), and have my q9300 OC'd at 3GHz using A FSB of 400 and 7.5 multi.

All the OC guides have taught me how to, and what to watch out for, BUT, I just can't get it stable at 1066MHz. I tryed bumping up NB a notch or 3, tryed switching off Vdroop, used 2.1v and 2.2ish V on the ram, tryed manual ram timings, still get lockups, and BSODS with game crashes etc.

The CPU OC is fine, have had no problems with it when the ram's at 800 using the 333/667 strap with a 400 FSB.

Any tips or templates? Have studied all the stickies and guides, just need a couple of pointers from someone with a similar rig.

BTW, seems to lockup while I'm using internet utilities, or media players, and I use the 400/1066 strap for the OC.

I've filled out the system form in my profile, need any more info? I'm an OC noob :-(

Welcome to the forums

Grab the template for your board and post all your BIOS settings please - You can find it in the sticky in the Intel overclocking section

Have a look at the stickies in the overclocking section and hardware section, plenty of general info there.

Thanks clunk, have read, saved, reread, the stickies, need some base figures for something similar and the GTLref stuff is a bit unnerving for a noobie, so trying to avoid that.

Feels like it's slower and a lot more unstable at 5-5-5-18 than at 5-5-5-15, also rasing dram volt to 2.19v kills the stab, even with a higher NB v(+-1.31v)

[Clunk]

There shouldn't be any noticeable difference in performance with 5-5-5-15 and 5-5-5-18.

On the face of it, the settings look ok for a relatively modest overclock.

Is it stable if you run 333/667 strap?

You might want to grab memtest86+ v2.xx and give the sticks a test.

[nolifer]

No errors with memtest, I've run it about three times in the past.

Ran prime with stock cpu clock(2.5GHz) and 1066MHz stable for 6 hours, it seems it's the cpu OC giving trouble, would increasing CPU volt a notch above auto help?

[!TIMMY!]

Yes I would try it. I need 1.35v (+ Auto Special Add) for my Q6600 to get to 400fsb, and 1.405v NB for my ram to get to 1066.

What cooling do you have?

[nolifer]

Looks like the board runs the reapers only slightly better at 1066MHz than at 800MHz. The 1:1 strap also allows better timing values at 400MHz FSB.

So running 2.8GHz 800MHz ultra stable and I'm chuffed.

BTW, If you're running 1066MHz with the reapers, you GOTTA set the tRFC to 72 or higher, won't boot sometimes if set to auto, which memset indicates as 54, atleast it proves I don't have to reflash the sticks, bad batch had a auto tRFC of 52, so yay!

I can run at 3GHz 1066MHz easily, with much higher voltages, but it's summer in South Africa, so 30+ deg. celsius everyday.

Thanks for the info

hmm i have the pc2-9200 reapers and they are hitting 612mhz on 2.23v with 5-5-5-18 and 5-5-5-15 on 2.3v


Maybe those reapers use a differant chip i have the entire dram set to auto except the 5-5-5-15/18 .

which version of the reapers do you have?

Might be different chips. I have used the 2x2GB 9200 sticks also and tRFC was fine at 54 all the way to 1200 on the DFI X48 board.
