help me overclock my i7 950 to 4ghz - Page 2

post #11 of 42
74-78c is fine on those chips. In reality they are probably safe up over 90, I wouldn't push it though But you could probably stand to bring the QPI down to about 1.3v or so, just check that it's stable, will help slightly with temps too.

now I'm at 4025mhz with 1.325v vcore(but 1.296v only at full load) and 1.355v QPI and everthing is auto except for dram which I increased to 1.6v (i think the defaule 1.5v was too low). im running prime right now hopefully it's stable

EDIT:

just got a blue screen within the first 5 minutes

afaik my corsair xms3 is rated at 1.6-1.65v (but bios has it at 1.5v default) should I leave it like that or change it to 1.65v? prime failed instantly on my setting -.-

try without Vdroop and set the volt to 1.65. mine is set at 1.63. i notice it goes to 1.67 when i set mine to 1.65.

also start off with HT disabled. just a suggestion.

Yes raise your volts to 1.65v for your ram. I have 1.660v set in my bios. Also set the timings in the bios for what the ram is rated for.

Do not disable HT unless your only gaming. Why suggest that?

What Bsod code are you getting?

thanks. ima restart now and set it to 1.66v then run prime again.

didnt bother to look at the bsod code coz i don't understand it anyway lol. next time i have a bsod im gonna post it this time

im not really sure about the timings on my ram so I have it at 1528mhz at CL10 something lol. im gonna get my overclock stable first before setting up my ram.

Cool. That bsod code will let me know what you need to change. It helps a bunch. Just look at the end like if its a 101, 124.

You have to disable HT and make it stable 1st then turn on later to avoid
hassle.

ok thanks. btw I just changed my timings to 8-8-8-24 and didn't bother with the others and after I rebooted my cpu-z still has the following. CL 10.0 tRCD 11 tRP 11 tRAS 24 tRFC 86 CR 1T. why didn't it change?

nvm. I got the correct timings to work now. running prime95 now
