Exclamation Timings problem with Gigabyte mobo and OCZ

Hey guys, I am having problems getting the timings that Newegg.com posts as possible with this pair of ram. I have OCZ Titanium XTC 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Retail. Supposedly runs at 4-4-4-12 with 2.1 volts. I set the voltage to 2.1, even to 2.175, I set it to those timings and my system becomes extremely unstable, blue screens, crashes, locks up. It does run for about 5 minutes though, and I'm able to play unreal 2004 for about 5 minutes sometimes.

I managed to make it stable with timings of cas 5-4-4-16-25-2T. Oddly enough cpu-z tells me that it's 5-4-4-18-26-2T. So I'm confused as to whether cpu-z is giving me correct timings, or to trust the BIOS where I manually set this. I had to disable EPP because it crashes the system also. I ran Memtest on each stick individually, when I had the looser 54418 timings, I got zero errors after 3 passes, on both sticks. When I ran memtest with 44412 timings I got 20 errors after 3 passes on both sticks.

On neweggs site a user posted that he had to change his northbridge voltage to 1.5 v. My north and south bridge are automatically set to default of 1.2 volts. I'm kinda scared of frying the board so I didn't raise that voltage to test it.

Any advice as to what's up? It runs in dual channel and at ddr2 800, so I'm happy with that. But the timings

Thanks!

A-Man.

That memory is rated to run at 4-4-4-15 2T @ 2.1 volts. You can safely bump the voltage to 2.2V if needed.

If you can't get the memory to run stable at those speeds without any errors in Memtest, you may need to get an RMA. Their customer service is excellent. You can get some really good help with them at the Official OCZ Support Forum. That's where I went for help with an old set of DDR PC3200 Platinum series that wouldn't play nice with my Abit board.

yeah I hit their forums, just wanted to see what other communities thought, maybe someone with this mobo. I can only put the voltage up to 2.175 max.

I ended up talking with a mod there who was very helpful and ended having to RMA my set. It is entirely possible that you got a bad stick or two of memory. Try contacting OCZ and telling them of your problem.
