Help on OCing OCZ Platinum XTC PC6400 Rev 2

[tomb18]

HI,

I was wondering if there were any tricks on overclocking this ram. So far I have been able to get

800 MHz, 4-4-4-15 (stock)
850 MHz 4,4,4,-15 at 2.05V
900 MHz 5,5,5,17 at 2.1V

Is this the best that it can do?
Thanks

I got mine to 1046 5-5-5-15 @ 2.1V. With my nForce 590 SLI board, the key was to set the RAM termination manually to 50 ohms and set max async latency to 10ns. All other settings on AUTO.

I have a 680 SLI board. Do these settings have any special nemonics? like t...?

Thanks

The rev 2 is now using other IC's then half a year ago, i have the rev2 with promos chips, which can almost do 1100mhz, 1070mhz full stable.
I dont know how the rev2 with PSC chips perform.
One thing no matter you're rev2 has promos or PSC chips, you need to change the tRFC to 42, and loosening timings to cas5, and if needed more subtimings.
Use Memset for timetweaking.

Thanks for the info. Last night I tried 900 at 4,4,4,15 2.1V with memtest and awoke to tons of errors.
Now trying at 850.
This is with 4G BTW.

I can hit 970 4-4-4-12 benchable, and haven't tried maximum stable.
I run 900 4-4-4-12 for 24/7 fully stable.

I think you can better first bench wit 2gb, and then test with 4gb.
Anyway, you should hit 900mhz cas4 easily.

My error, it was 940MHz 4-4-4-15 that gave errors. Today I ran memtest all day at 900 MHz 4-4-4-15, 2.1V

I guess thqat's pretty good for cheap ($100/g) ram these days.

The ram does with it is labeled to do, for me anyway, no extra voltage help me at all. The sticks I have could do about 850, 4-4-4-12@2.1~2.2v. Nothing special IMHO.

yeh i cant seem to overclock this ram worth a :banana::banana::banana::banana: either, im keeping the ram, but im gona be swapping it out for some faster ram, and im gona use this in another pc.

although it doesnt seem to be able to take much in the way of mhz i was able to squeeze 4-4-4-12 out of it at 2.0v, i did 15 passes of memtest86 overnight with no errors, that was a good 6-8 hours. Im gona run a memory test in windows now for a few hours also.

I'm afraid the Gigabyte board you have has not been a great overclocker overall. Tightening the timings should do you some good though. :)

its a finicky board to say the least, but so far i havent had any real problems with it as far as some of the nightmare storys ive been hearing about this thing eating ram and video cards lol

There's someone on the forum thats at 4-4-3-8 1.9v with these rams.

How do you tell if you got IC's or Promo chips?

mine defaulted to 10-4-4-3 @ 1066 on stock volts when i booted up my 2140 with bsel mod. right now i got it running at 8-4-4-3 @ 824mhz
