Is it safe to OC 1600 to 1866? Please Help..

[19nero68]

My question might be a little newbish, I built my 1st own system or gave any thought to the usual head scratching in regards to bottlenecks, system limitations, actual vs. claimed specs, etc.

I have a ASRock 970 Extreme 4 MoBo and the specs said that it can handle everywhere from 1033 to 2100 RAM speed. I want to go with 1866..

so i bought GSkill Ares 1866 4gb(x2)..
my FX4100 CPU can handle 1866 of memory..

but when i look at bios..

DRAM CONFIG

if i'm not mistaken it is called "Profile"
9-10-9-28 1.50v DDR3 1866 is indicated in there.

but on DRAM Frequency.. it is set as "auto" and set as DDR3-1600..
________________

What if i change the frequency to 1866? is it safe?

please help.. thanks a lot in advance.. =)

BTW.. My PC Specs are..

CPU- FX4100 3.6ghz
MoBo- Asrock 970 Extreme 4
RAM- Gskill ARES 1866 (4gb x2)
PSU- CM GX650watts
GPU- Sapphire HD6850 1gb GDDR5

as long as your ram can handle at that speed and stable ... no problem

yeah!! i changed it to 1866mhz without encountering any problem..
but one more.. http://www.overclock.net/t/1250397/1600mhz-8-8-8-ram-vs-1866mhz-9-10-9-ram-for-gaming it that link i read that "ROMIN" changed the ram timing to 9-9-9-28... and the default timing of Gskill Ares 1866 is 9-10-9-28..
can i also change mine to what ROMIN did?

thighten timming maybe ... hmmm , just for to know , go benchmark ram 9-9-9-28 vs 9-10-9-28 with Maxxmemm2 software and submite for result, take highest result
i think,the score isn't too far (near same)

what's the best potential i can get with my 8gb Gskill Ares 1866 (2x4gb) with my MoBo Asrock 970 Extreme 4..

in bios, in DRAM timing control..
i saw this,

CAS# Latency (tCL) - 9
(in description: Min 5, Max14)

RAS# to CAS# Delay (tRCD) - 10
(in description: Min 5, Max19)

Row Precharge Time (tRP) - 9
(in description: Min 5, Max19)

RAS# Active Time (tRAS) - 28
(in description: Min 15, Max40)

can you suggest a good timing that my components can handle??

default from factory 9-10-9-28 more stable than 9-9-9-28 (tweak) also score not different soon download Maxxmem2 for to know !

heres the result.. i dont know how to understand the result. =( i'm newbie..

Mem-Copy: 12839 MB/s
Mem-Read: 10168 MB/s
Mem-Write: 8546 MB/s

Reached memory score: 9.36 GB/s
Mem-Latency: 67.2 ns

which win ??? 9-9-9-28 or 9-10-9-28 .. i don't see compare

man i changed it to 9-10-9-28 then after saving and exit..
at windows start up.. i encountered blue screen.. then asking to launch windows for repair or start windows normally..

why did it happened?

 

[henydiah]

because your ram default at 1600 and you change tweak ran over that ... in above you said it Ok and stable .. maybe need more voltage at ram max at 1.6-1.62 or go back default your ram

man how would i compare results?
in reached memory score i think the highest is the fastest? am i right?

but in the latency score? the lower the better??

 

[henydiah]

i'm sorry if you hard and difficult to translate my language ... it's just different gap
... yes right in above , highest is better and low latency is better
ex. test compare as long as stable and no BSOD :
1600 9-10-9-28 score : 92 latency 46 stable/ no BSOD ... keep at screenshot
1866 9-9-9-28 score : 102 latency 46 stable / no BSOD .... keep at screenshoot

and than setting your PC at higher score and ignore latency and keep it ... i think you know wich better
