i posted that screen only as an example of submitting his bios screens / sorry for the confusion

redenvy

if you scroll up, i did post two pictures of my BIOS and one of CPU-Z when i was asking voltage difference questions :). I will take a picture of my RAM information too though... i think i know where to look.

For the linking you would go into guru utility and select DRAM Speed (CPU : DRAM) and set it to 1:1 (My preference and if we achieve a good overclock will set your ram to at or near rated setting). I think the default setting would be unlinked.

For ram timings they should be under advanced chipset features.

redenvy

ohh i see.. when do you think i should change the ram stuff? once i get a stable clock on my cpu?

HD_Monkey

Well it depends. I would normally start out with loose ram timings 7-7-7-20, ram linked 1:1, voltages at default, and fsb at stock speed. Then I would gradually raise fsb in increments and stress test while monitoring temps.

It really depends on where you are in the overclock. If you can get to 3.5 on stock voltage with good temps. then you can likely squeeze some more out of it with some voltage tweaking.

For you:

I would set ram voltage to 1.95 just for comfort.

At the first BSOD or system freeze, go in and bump the voltage a little on the cpu vcore. Run test again. Just don't go upping the cpu voltage too high. It's unneccesary and will only increase heat. I would use 1.45 as a cut off point before we start looking at raising voltage any more on ram.

Post back with your progress.

Ok heres my gameplan before i start it lol... Right now im at 3.3ghz stable.. ran a 9 hour prime95 test with no problems. stock cpu voltage and ram at 1.9v

so my plan is bump up ram to 1.95v and set it to 1:1, then stress test
then bump up clock by 10 and stress test a couple times

sound like a good idea?

linderman

yes thats a good idea; BUT dont leave your cpu voltage on AUTO that will often times send too much juice to your cpu


use core temp(free) it will give you your CPU VID number (thats a voltage setting)

then you can factor what to set your voltage at

ALWAYS monitor your temps

HD_Monkey

Ditto on that. We don't want any voltage settings on auto or default. Set them manually.

linderman

in the bios you will want to add about .03 volts to that number


example = my cpu has a VID of 1.25 so I set my cpu voltage in the bios to 1.28 to account for V-droop

redenvy

i've found that core temp seems to always be 5 degrees under real temp but i do use both programs

linderman

what does core temp report your VID as ?

redenvy

1.3500v

redenvy

okay so far so good with RAM stress test. Now at 1.95v and 1:1 setting. temps never go above 58. Tomorrow I will bump the clock of the CPU up to 3.4 and see how it goes.

Heres some ram info from CPU-Z


Memory Type DDR2
Memory Size 4096 MBytes
Memory Frequency 370.0 MHz (1:1)
CAS# Latency (tCL) 5.0 clocks
RAS# to CAS# (tRCD) 5 clocks
RAS# Precharge (tRP) 5 clocks
Cycle Time (tRAS) 15 clocks

linderman

looking good; I think! what is your cpu voltage at; you set your voltage at 1.38 and that should get you to 3.6ghz as long as your stress tests dont exceed 60C your golden I wouldnt try for anything above 3.6

redenvy

My current CPU voltage is 1.36 and i've got it clocked at 3.4ghz running stress tests all day. 3.6 sounds awesome! my goal was 3.5 so thats great. I will post with the results when im back from work.

linderman

I would try 1.36 volts and 3.6ghz ........if it fails stress test; then shoot for 1.38 volts



that will be about the end for "normal" overclocking; beyond that is the extreme stuff ...........ALWAYS watch your temps from now on


make sure your cpu fan is always running at 100% speed


a few more high rpm case fans would probably be a worth while cheap investment too!

you must shop by RPM though........common 120mm fans rotate at 1700rpm; but there are better models which hit 2800 rpms and more

they are louder = cooler / quiet = hot

redenvy

how do i go about making sure my CPU fan is 100%?

also i have this case

http://www.newegg.com/Product/Produc...82E16811119160

Would you recommend replacing maybe replacing one of the larger fans with 4 smaller high rpm ones?

linderman

that case is well ventilated; plenty good as is


BTW: thats one of my #1 fav cases

linderman

the cpu fan speed options are in your system bios / general under a section called PC Health & Monitoring or something similar


generally their is some sort of "Cpu fan speed" set that to "disabled" and the fan will run on high rpm's all the time

redenvy

Yeah i love the case :) I will check the bios settings once i get home and will post a SS if I can't find the option.
