Is Kingston Value RAM holding system back?

My system is: Phenom II x 2 555 @3.7, 2x2BG Corsair XMS and 2x1GB Kingston Value RAM, ASUS 890GTD Pro/USB3 MB

When OC'ing when i got to 3.7GHz on CPU and RAM at stock 1400Mhz (1333 with FSB at 200) I got an critical error in Prime95, when i drop RAM speed to 1067 i don't get an error.

Question: Am i limited on the overclock due to the Kingston RAM that does not come with a stock heat sink and is just cheaper RAM. If so could i actually get faster speeds and real world results by taking out those 2 1GB Kingston sticks and overclocking the remaining 4GB further???

Thanks in advance for the help!

Replacing your 2GB of memory with 4GB may, or may not, impact your OC, but will definately improve your performance within your OS.

Probably need to up the voltage for the RAM to reach 1333. Try increasing your memory voltage one step at a time and rerun Prime95.

Moving up to DDR1600 (Running at 1333) will let you overclock without worrying about the ram...

Value ram usually does not like to overclock much. You could try a voltage bump on the ram and go back to 1333. See how far you can go.

it's at 1.55v right now. What is the next logical bump up? Also how long would you run Prime95 Blend when OC'ing in between each frequency boost? (I realize in the end i will want to run a 12 or 24 hour test)

In Prime95 Blend is it good to custom the RAM usage to use 100% to fully stress the RAM and CPU?

Do you know the exact model of the memory? Link with specs? Without knowing the specs I would bump the voltage in the BIOS one level and rerun Prime95.

Personally, I run Prime95 for an hour or two between settings changes. When "dialed in" I will run for 4 - 8 hours. IMHO anything more than that is overkill.

Thanks for the info, Both sets of RAM stock are 1333Mhz CL9 1.55v. The Kingston Value RAM does not OC nearly as well as my Corsair (because of stock heatsink). So with 210 FSB and 667Mhz the RAM runs at 1400Mhz which i'm scared is to high for the Kingston. Do you think that is the case?

OC AMD very worth use Dual RAM, because Mobo support dual RAM
The kingstone value ram is good for CPU Black edition !
it have limited in CPU non Black edition:
1333 : max FSB 255 x 14 multiplier get 850( CPU-Z) VDIM:1.602 CPU clock 3.5Ghz
1067 : max FSB 288 x 14 m get get 753 (CPU-Z) CPU clock 4.018Ghz VDIM 1.63
800 : max FSB 305 x 14m get 602 (CPU-Z) VDIM 1.45 Clock 4.2Ghz
OC Ram value need RAM Heatsink + mini fan

Just run the ram at the fastest speed closest to it's rated speed. Tweak the cpu to where you want it, then work on lowering timings.

Will i get better overclocks on my CPU and/or RAM if i force/leave my HT and NB frequencies at ~stock 2000mhz? Ive read that somewhere and want your opinion?

You can play around with it a little to help find a good ram frequency, but clock for clock there's not going to be a big difference with a faster HT link running.
