N00b memory stability and overclocking questions

post #1 of 7
Thread Starter 
hey guys, im new to overclocking and what not however i read up some and seem to have understood the concept more or less... i would appreciate it if you could help me out in my search for reaching the best possible setup on my system.

up until this morning i was running on 2X512 GeIL 2.5-4-4-8 on dual channel setup. mobo is D865PERL with ntel Prescott 3.0, everything was fine.

i got my hands on some super Talent memory sticks 2X512 2.0-3-3-6 i believe...from what i read i understand these are excellent for overclocking.

im not looking for crazy speeds or anything like that however would like to get the best out of these 4 sticks together.

i put the super talent in and restarted, my system defaulted to DDR320 speeds by setting the GeIL sticks to the Super talent timings @ 166MHZ, from what i more or less understood this was not good at all...

i read up some more and saw some methods of bettering the setup. essentially i went into my bios and put the speed from auto to 400MHZ, reboot--->no go.

went back to bios put timings at 2.5-4-4-8 the original GeIL timings and left the speed at 400MHZ, reboot--->stable and working

however by this process i actually sacrificed the better timings of the supertalent didnt i?

this is where i could use your help, what now? should i try different timings and see where i can end up with the optimal setup....what timings would u suggest whereby i keep the 400MHZ speeds?

oh and on CPU-Z it shows FSBRAM ratio as 1:1 is that good or did i actually slow something down? because before it was 5:4 at DDR320 speed 2.0-3-3-6...

anyway would appreciate any help you guys can give me

The best performance achieved is through a FSB:RAM ratio of 1:1. You only want to run a divider favoring higher FSB and lower memory frequency when your RAM is limiting your OC.

hello, thanks for your reply

i did have the system on Auto with all 4 RAMS in and it auto defaulted to 166mhz...

as for using 2.0-3-3-6 timings for all 4 rams, how do you think the GeIL sticks would handle these timings? before when set to 2.0-3-3-7 @ auto they worked on 166mhz, should i just try 2.0-3-3-6 @ 400mhz?

also i havent fiddled with the vdimm, where do i find the options for that?

I would in fact, bump the vdimm up to 2.8 V. You might be able to get the GEIL to run at CL2. Or instead, I would set your timings to 3-4-4-8 and try to run 1:1 with your overclock.

Hmm, could you fill out your User CP System specifications?
(http://www.overclock.net/usercp.php then click Edit System Specs and fill-in )

Edit: As mootin suggested, you will not be able to control Vdimm with your motherboard, this is the PDF for your motherboard it details all the BIOS settings:

typical intel product code, i doubt you can overclock or change the vdimm options

is the pc a dell, gateway,hp etc ?

lol, no PC is not a dell or gateway or any commercial company, i actually built it myself with the limited cash and deals i could scrape here and there.

i agree the mobo choice is not the hottest but it was purchased for a low price at a time when i needed to upgrade the mobo badly.

as far as my user profile system specs, i updated what i could for now, time difference is a ***** and i got to get up tomorrow morning so im tired hehe....

in short, what are my choices, what CAN i do as far as improving the RAM performance with my current setup, i promise when i get the chance i will upgrade to something more OC compatible
