im looking at upgrading my ram. right now im running corrsair xm3 1333mhz 2x2. its awful ram. always has errors. so im wondering about this g skill ram. lots of people seem to run it.. im wondering though.. if i buy ram rated at 9-9-9-9 at 1800mhz.. does that mean if i lower the frequncy to say 1600mhz ill be able to run tighter timmings?

Q - What MOBO?
Q - What CPU?
Q - Wat DIMM slots?
Q - What if any 'RAM' settings did you enter into the BIOS?

o yea lol

A - right now msi 870a-g54. upgrading to crosshair IV next 2 weeks
A - amd 1090t. overclocked to 4 ghz. water cooled. hopefully farther with new mobo and ram
A - running dual channel ram. ? 2 x 2gigs or 2 x 4 gigs
A - right now its just set to 1280 mhz. the ram isnt even stable at its set 1333mhz. 9-9-9-9-24 i think.

im looking to over clock lots sence my computer is water cooled. i like to push everything i can. this computer is just for gaming and it also has a 6970. soon another one.

Okay, you've got problems with your 'current' MOBO, but you listed totally different components.

Future rig:
RAM: G.SKILL Flare 4GB (2 x 2GB) DDR3 1800 F3-14400CL9D-4GBFLS
MOBO: ASUS Crosshair IV Formula/Extreme
CPU: AMD 1090T

Will all work together, BUT you'll need to OC the FSB and Manually set ALL of the DRAM, AI OC, and CAS timings to use 1800 MHz RAM.

Current rig:
MOBO: MSI 870A-G54 http://us.msi.com/index.php?func=proddesc&maincat_no=1&...
RAM: {assuming} http://www.newegg.ca/Product/Product.aspx?Item=N82E1682...
1333 MHz 9-9-9-24 @ 1.5v
CPU: Unknown
DIMM Slots used: Unknown

Slots:
CPU: | 2GB | 2GB | empty | empty | ; use the ONLY the Black slots with 2X2GB set

BIOS:
FSB/DRAM Ratio -> 6.66
//Adjusted DRAM Frequency (MHz) should display 1333 MHz

Advance DRAM Configuration / Enter {optional}
set the timings 9-9-9-24
1T/2T Memory Timing -> 2T

DRAM Voltage -> 1.55~1.60v
Save & Exit - Yes

More than likely, you either have the RAM in the incorrect DIMM slots or the DRAM Voltage isn't sufficient and the RAM is underpowered so the RAM is producing errors.

your good lol.. yes the msi board and xm3 ram u listed is what i have right now. and the 1090t.. im just upgrading the mobo and ram.. the ram is in the black slots. soo reading online 1600mhz with cas7 seems to be a nice spot for the 1090t.. thats why im wondering with 1800mhz ram can i lower the frequency and run tighter timmings? like is ram that is able to run at higher frequencies able to be run at lower frequencies at tighter timings? or do i have to get 1600mhz ram with cas7?

I get what you're asking, and the you'd need to ask G.SKILL with the SPD and JEDEC CAS timings are other than the 1800 MHz 9-9-9-24-2N, my guess they're the same for 1600 MHz and 'maybe' 8-8-8-24-2N, and 99.99% certain they're not 1600 MHz 7-7-7-24-2N.

I've built off the 2000 MHz Flare and they were 8-8-8-??-2N edit: {running at 1600 MHz} off the top of my head.
