I'm looking for some suggestions on overclocking mostly through my FSB if possible, at the moment I'm running my FSB at 212 with a multiplier of 19 for 4ghz @ 1.4 Vcore. It's stable and has gone through prime95 and intel burn test for over 12 hours.
My ram is dual channel, but cpu-z and Aida64 read it as single ever since I started going through my FSB, also the ratio is 1:2. I have read that 1:2 is fine and I have also read it isn't. I also know nothing about tweaking ram timings at all and I'm hoping someone can explain or help with tweaking them properly if needed.
CPU: AMD Phenom II X4 965
Motherboard: GIGABYTE GA-MA785GM-US2H
Memory: G.SKILL 4GB (2 x 2GB) DDR2 800 Dual Channel
you got your chip to 4ghz, what more do you want? looks like you're squeezing everything you can out of that thing. 24 bank cycle time? lol..i cant remember, maybe that was normal for ddr2. you should probably set the ram to all defaults and try to get it 1t command rate. default the timings, frequency, etc. and see if it will do 1t.
Well I tried to push for 4.5 but that was a no go no matter what I did, even went past 1.55V and tons of combinations of FSB and mult but no luck. Since I didn't make it to 4.5 I thought I should go for the 2nd best thing and that's 4.4ghz. I am currently running 4.4 @ 18.5 multi with 240 FSB, HT link 2400 ( I have tried lowering it to about 2100 but fail to boot into windows) with my ram still at 6 - 6 - 6 - 18 2T ( I have tried putting it at 1T but cant boot into windows even without a OC ) with 2.0v @ 3.33 mult for 800 mhz. I haven't touched NB or SB voltage or any of that because I never have and I don't want to be over volting something I shouldn't. It's stable to boot into windows but the second I start Prime95 my first core always fails, I have no idea what to do at this point to make it stable so any suggestions would be great!
Also the default timings for my ram is actually 5 - 5 - 5 - 15 24 2T.
You have your RAM sticks in the Dual channel slots? I'd assume so since apparently it said dual channel before you changed the FSB. Dunno why it would change.
I've never seen OC'd RAM as offering much performance gain, but suit yourself.
Iv tried everything I can think of, different ram timings, upping NB volt, SB volt, ram volt, lowering my HT to 2120 then to 1920. I have tried raising the NB freq and lowering it, everything I can think of shy from raising my Vcore which its already at 1.575, 1.552 in windows because of Vdroop. I cant seem to get prime 95 to run more then 10 minutes without 1 core failing. I'm at a complete loss at what else I can do at this point. I'm not even hitting the heat wall of 55c at load from prime I hit 50c max.
I'm big into gaming, iv had a 4.0 OC for a long time and never truely pushed my cpu to the limits due to a shitty aftermarket air cooler. Since buying my H100 water cooler thought I finally would see what I could push.
