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???
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
