Difficulty finding timing settings KVR1333d3n9_4g

post #1 of 6
Thread Starter 
Evening,

I'm having some trouble finding the right timing settings for 3 PC10700 KVR1333d3n9_4gig ram sticks I just bought from Kingston. They run stock at 1333mhz, but seem to register on the bios as 1066mhz ram - maybe this is why the default timing is messing with stability. I can't seem to boot with anything above 1333mhz...

Ive tried a number of different suggested timings, such as 8-9-8-24 but to no avail. I was hoping someone with more experience can lead me in the right direction.

System specs:
i7-950 @ 3.87 ghz (O.C. @ 1.41v, x24 multi) w/Corsair H50
Asus Rampage III Formula motherboard x58 chipset (tri channel)
Ram is cooled with aftermarket copper heatspreaders.

I don't claim to be an expert by any means when it comes to overclocking, rather I should point out that this is my first time manually manipulating ram timings... but I figure that if I Want to get the most out of this rig, I should try to optimize it myself.

Thanks for any help you are able to give.

increase the ram voltage a bit, not enough juice can cause that
and while doing this, loosen the timings to 9-9-9-27 with a command rate of 2T to increase the odds it will work.

test with memtest and intel burn test to ensure it has been properly overclocked and is stable

the speed seems to be locked at 645mhz, it doesn't seem to matter how I Change the timing and voltage. They register as changed on CPU-Z, but the speed is no different. Is it because I am using CPU level up on my bios?

Anyone with experience using the Rampage III bios please let me know.

successfully overclocking at the moment at 766mhz dram frequency. Timing is set at 9 - 9 - 9 - 27 - 2T, will not boot with 1T.

950 is now at 4.2ghz, 191.5mhz x 22 multi. Temperature is hovering around 32 C, under load around 50 C. I'm thinking im going to push this, see if I can manage closer to 5ghz. I see somewhere that someone got to 4.7ghz on aircooling, though it was unstable. Im using the corsair H50, i might manage around the same with a little more stability.

The vcore voltage is at 1.42, is this too much for 4.2ghz?

Hi mate

I dont have my old notes, but at BLCk 200 x23 on i7 950, its about 1.5v for me. Main thing is your temps, your temps are ok. Plus if you go to user control panel, you can edit your system specs, makes things a bit easier to see what you got there thumb.gif

Oh by the way if you end up on the x23 multi you might need to go tighter settings on the ram, at 4.8ghz and up. Let me know how you go

thanks much for the suggestion m8, I appreciate it. I just managed to get 4.4ghz multi 23 x 193mhz, ram is at 1600mhz, same timing. CPU voltage is at 1.43.

Just out of curiosity, how does HT play a role in stability and overclocking ceiling? Im still running at 8 threads at this speed.
