Help Ram Overclocking

post #1 of 8
Thread Starter 
Hello,
Yesterday I received my 2 new Corsair Vengeance 8GB 1600mhz kits (16gb) [Low Profile]
I am not very familiar with RAM overclocking so I went and did my research first
because when I first installed the memory I was running at only 888mhz (or so)
I have it now 1333 I don't wish to achieve 1666 because I cannot boot windows when I try

but anyways here is the issue that I am now running into
I have my phenom ii x6 1100t running at 4.0 ghz (it is stable I ran occt for a few hours)
but whenever I play games or use adobe applications etc, I blue screen after so long

the memory comes at stock 1.5v I gradually bumped it 1.65v still running into this issue

any help will be greatly appreciated,

Specs:
Mobo: Asus m4a89gtd pro/usb 3
CPU: AMD Phenom ii x6 1100t w/ Thermaltake Frio OCK
RAM: 16GB Corsair vengeance LP
GPU: His Turbo 6970
PSU: Kingwin Laser 1000w

Set the memory to the rated frequency, voltage and timings. Set CPU-NB voltage to 1.4v. Make sure your HT Link and NB frequency are at 2000mhz (or if you're overclocking via FSB then close to 2000mhz). Run memtest86+ to check for memory stability. If it passes that, you can leave the memory settings alone. Then to stabilize you may need to adjust the CPU-NB voltage and CPU vcore. CPU-NB voltage just so you know is basically the voltage applied to the memory controller on the CPU, so this helps stabilize higher memory clocks (like 1600mhz instead of 1333mhz) and also higher capacity of memory (like 4 sticks instead of 2)

Thanks for quick reply,
though how do i set my ram timings,
ive only been tweaking the mhz and voltage
post #4 of 8
It will be in the bios, something like Advanced DRAM Configuration or similar. You should only worry about setting the first 4 timings - CL (CAS latency), tRCD, tRP, and tRAS - and everything else can be left on auto. Also set the command rate to 2N or 2T, some boards list N and some list T so it just depends.

Okay so I did what you said to do in the bios and I ran memtest with no errors but when I play games or run applications like photoshop I still blue screen, I am not to sure what to do at this point,

Well starters Im not familiar with that motherboard your running but i have an 1100T cpu also and I dont need cpu-nb at 1.4v for stock 2000mhz. I have 1866mhz memory and run the cpu-nb at 2990mhz with 1.25v and cpu running at 4140mhz (230x18) with cpu-vdd 1.43v and vcore will ramp to usually 1.48 on prime95. The 230 fsb/ht is so that I can boost the memory to its rated mhz or I would be stuck at a max of 1600 if I leave the fsb/ht at the factory 200.

Like the other guy mentioned, set the ram to the factory specs BUT make sure you have the memory voltage set correctly too. Unless its intel memory rated to 1.5v yours is probably 1.65, mine was and the bios sets it to 1.5v on me, so I needed to configure the voltage on the memory, and set the timings too because the motherboard had the timings a lot slower than the factory setting.

Also rather than needing to overclock the fsb(ht) to achieve 1600mhz isnt there a multiplier/ratio option in the bios near the memory features? That might allow you to set it to 1600 without needing to tweek anything else too.

edit: Remember no two parts are the same, even though we all have 1100Ts here so far, that doesnt mean you can run at what my voltage is or someone elses. At least you see the range of voltage that we all need to run for the same results. And I would try leaving cpu-nb voltage to auto unless you start overclocking the cpu-nb.

thanks for the input Racer, but i managed to get my RAM stable by using what Dopemin3 said, though i settled for 1333 instead of 1600.
been running fine under stress for the last 6 or 7 hours.
Thanks for the help again guys
