eVGA 680i memory issues! Buyers beware.

Run in sync mode. I'm doing 850MHz 3-3-3-9 1T and it's faster than 1200MHz 4-4-4-8 2T. No lockups, either. Whatever works, I guess. I'm just going to wait for a BIOS that fixes this **** before I waste anymore of my money on memory.

How do you keep the processor overclocked if you run in sync mode though?

Just put the memory in sync. You can still change the FSB. My FSB is at 1600MHz, and the memory is at 800MHz.

Anyway, I'm not stable at 850MHz 3-3-3-9 1T anymore. I can't get any faster than 800MHz 5-5-5-15 2T now. Ridiculous. SPP and MCP voltage doesn't seem to fix anything this time around, so I guess it IS 100% the memory right now. Going to contact Crucial and set up a RMA, I guess.

How is your system now tacos4me? Less than 30 days and my memory is already starting to puke again. I'm getting lockups in games again but can make things stable if I lower the memory from 1066MHz(factory spec) down to 800MHz. Same crap as last time. I just need to get a new motherboard and RAM but talk about a major PITA

I've found this board just doesn't like anything but a 1:1 FSB/memory ratio. I was getting random freezes left and right until going with this, and now it seems stable @ 400FSB, 800mhz 4-3-3-4. *knock on wood*

Also, I found that it just wasn't worth it trying to boot into a 1T command rate. It just doesn't seem to make much difference on the Intels like it did w/ the AMD's. I'm guessing it has something to do w/ the extra cache. Check out my SuperPi benches w/ 1T command rate vs. 2T:




14.610 w/ 1T vs. 14.828 w/ 2T

Hardly even worth the hassle. I'm now running a faster time (14.344s) at 2T @ 800mhz 4-3-3-4 than I was w/ 1T 4-4-4-5 (lowest timings I could get it to boot @ 1T with)

It's definitely not the overclocker my P5B Deluxe was. Had to make zero memory adjustments on that one.. booted right into 500FSB w/ a divider set to run my G.Skill @ 1000mhz and was prime stable to the day I swapped it for this one.

But, SLI comes with a drawback or two. Still worth it, IMO.

So what would be the best motherboard to get that's not SLI? I only plan on using the 1 8800 GTX anyway. I just wanted the 680i because of all the good overclocking capabilites it had. Is there anything equivalent that's not designed for SLI?

Gigabyte DS3. It's a great little overclocker at a good price.

1 vote for the Asus P5B Deluxe here. I actually have a lightly used one I'd be willing to sell you for 50$ off retail.

Why'd you make the switch from Asus P5B to the 680i anyway? Oh yeah, does that board support 1066MHz memory?

[GitDat]

It seems like the only motherboards I see that can do 1066 RAM are SLI

SLI. P5B Deluxe doesn't support it. No recent Intel chipsets do, that I know of.

And yeah, it supports 1066.

I'm running great right now. I just gave up with the high frequencies. Currently running 850MHz (1:1) 4-4-4-8 2T with the same sticks I was having problems with. I have some cold boot issues if I leave the computer off for longer than an hour, but other than that I've been stable.

Also, I've had more luck (less problems ) running at a lower voltage. I believe 2.2v+ might be causing the problems for people.
