i7 860 overclock - Page 4

post #31 of 50
Thread Starter 
next im tightening up my ram timings..
181x8 = 1448 @ 6-6-6-20
or
181x10 = 1810 @ 8-8-8-24

going to run memtest86+ for a couple of tests(3-4)

then prime95 for an hour or so...

lower timings are better than higher freq so i'll try the first option first...

Are you able to drop the cpu volt down a notch? Because mine is running faster on lower volts.

currently my RAM is running 1448mhz 6-6-6-20 running stable for 4 runs of memtest 86+

.::6-6-6-20 1448mhz RAM::.
running 181x8 = 1448mhz
memtest86+ for 4 runs sucessfully @ 6-6-6-20
1.6v vDimm <- default/stock voltage

uhh i dont think i could honestly

i could try but im pretty sure i cant, you run lower volts because you have an i7 870 which runs a high stock freq.

if i did lower by vcore what should i lower it to and would i need to lower my QPI/vtt?

thanks.

ps. is 6-6-6-20 1448mhz too high overclock for 24/7 use?

Does your motherboard bios have any vdroop or load line calibration (LLC) options? I only need 1.24v (1.28v load) for a 4GHz overclock.

hi nitrousX,

yes i have LLC enabled, i think maybe my cpu is volt hungry

also should i have spread spectrum disabled?

ps. do you have the same cpu batch as me ?(doubt it)

You need to disable all spread spectrums. I'm not really sure of the batch sorry I bought it about two years ago. What is your voltage under load? Do you have any LLC level (level 1, 2, 3, etc.,) options in your bios?

i bought mine like 2 years ago but i tore off the flap of the box with the batch number label XD.

as for LLC levels i have either auto, disabled or enabled therefore i enabled

spread spectrum i disabled already

voltage under load is 1.31v, idle is 1.296v

ps. is my ram safe to run at 6-6-6-20 @ 1448mhz 24/7?

You should run your memory at it's rated speeds (if possible).

I noticed that you have a UD4 motherboard. A friend of mine uploaded this overclocking tutorial on youtube a while back. His setup is nearly identical to yours.


Hope this helps.
