Kingston HyperX DDR4000 trouble...

Recently I bought a stick of 512MB Kingston HyperX DDR4000 to complement my 2 sticks of 256MB Kingston HyperX DDR3500 (rest of the system specs in my sig).

For some reason, I cannot get the DDR4000 (500Mhz FSB) stick stable at an FSB 460, when my 3500 sticks do it without a problem (the 3500 sticks can run memtest86 all night long w/o trouble, when the 4000 starts shooting errors in just a half hour).

Before I got this particular stick of 4000, I had to exchange it with another I bought from Best Buy. The previous one was chalk full of errors even at (the CPU's) stock speeds. This one runs fine at the CPU's stock speed, but it cannot get anywhere near it's rated speed w/o erroring out quickly.

Is there anything I may be doing wrong, or does Kingston not expect people to use this RAM anywhere near there rated speeds anymore?

    What latencies are you running it at? That PC4000 needs to run at 3-4-4-8 or it will error and quite profusely at that.

    Default for the board... but I'll double check.

    Set it manually to 3-4-4-8 or whatever the equivelent is for that board as the SPD settings will want to default to 2.5-4-4-7 or something close to that until it hits 250fsb and that's error city for that ram.

    Well, I thought it was CAS 2, but I just read it's CL 3... so now the settings are at 3-4-4-8, rather than 2-4-4-11. I'll see how things go... wish me luck.

    The memory must run at 3/4/4/8. It will not do the timings the 3500 is SPDed to (Lower than 3/4/4/8).

    As is typical with all my posts, I must note that it really was a bad choice to purchase PC4000 for an AMD computer. Not only can PC4000 sticks not run the desired 2/2/2, the extra price is unwarranted because the motherboards themselves are scarcely capable of the speeds PC3500 offers.

    2/2/2 PC3500 is the best type to shoot for when assembling an Athlon system. Any timings that are slower than 2/2/2 just suck for AMD, and any speeds higher than PC3700 are rare.

    Well, I just checked on Memtest, to find 100,000+ errors AND COUNTING! :banghead:

    I should <i>also</i> note that mismatching memory speeds is also bad. Especially when there's as great a rift in default performances as there is with 3500 and 4000.

    Actually, I was going to get 3700 (Kingston doesn't sell PC3500 anymore) but this stuff went on sale at BB for $99 (the PC 3700 was going for $116). I'm already running the 3500 over it's rated speed (it's speed is 430, I run it at 460).

    The tests I'm running at the moment are w/o the PC3500 in the system.

    My second comment didn't relate to memtest. :)

    But it still crapped out, dispite being the only DIMM installed. I think I'll just return this for a refund, and get the lower latency stuff.

    Thanks for all your help guys!
