Well.. as the title implies I have OCZ PC-1600 DDR-3 Ram.
Precisely:
OCZ Obsidian 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model OCZ3OB1600LV4GK - Retail
Dual Channel for Intel Core i5 & i7 CPU & P55 chipset
Here is the link if you wish:

Anyhow, 93$ Ram,.. with a $30 rebate, I haven't mailed in.. SO still RMA (able) if I wish.
This stuff won't hit 1600.. not on stock speeds..
I've tried every multiplier and FSB between 133 and 200 and SPD between 6-10.
It is most stable on auto settings (the board ramps up voltage automatically for all parts, go figure) -- If I manually set the voltages it is less stable,.. shrug.
I can run the ram at 145FSB x 10 and run Prime95 for 24hours straight without an error (I stop it then) -- I also boot with memtest ISO 4.0 and let it run a few hours at this rate -- this is the most solid 'fastest' speed I can achieve with zero errors.
Now I can go up quite a bit with 'few' errors.. but 1 error is too much for me for RAM.
At 1600 it simply isn't error free. Computer and memtest recognizes it as PC-8500.. a clue? Shrug.
I guess, any more tips for me to try? Or am I shot?
The cpu is on WC now, and at stock speeds runs 19c idle, and 30ish at full load.. so it can clock well (4.2 hasn't been an issue).
I'm thinking the RAM is the weak link here for whatever reason, and maybe some more reliable , perhaps a little more expensive different branded RAM would be more compatible with this P55-UD4P board and i5 chip.. might hit 1600 as designed?
Am I wrong?
This is OCZ, yes.. but it is 90$ OCZ.. considerably cheap imho for ddr3 1600 .. Maybe some mushkin or corsair would make things 'work' ?
Let me know what you think.
