Questions on oc'ing

[ntdouglas]

Yeah, the utilities that report wrong cpu speed are reading correct fsb
speed but there cpu speed = 9 multi. For instance, I'm at 475 fsb on multi of 7 = 3.32g. The utilities reporting wrong cpu speed are at 475 fsb = 4.27g. Thats 475 fsb on multi of 9. Wouldn't I have to be on water cooling or something to be at almost 4.3g? Anyway, I booted stable at ddr2 750 3-3-3-10 on 1:1. Pcmark05 ram score of 6827. Highest pcmark05 ram score is 7261 at ddr950 on 1:1.
I found that very interesting.

I just checked. cpuz,everest report correctly. Coretemp,easytune are wrong. I dropped divider to 6x400 and ran mem @ 500(4-4-4-10) just to see if i could.
[edit] You should use the free version of everest to test your mem. It's really fast and you can check read/write/lat it also is a good info tool. Just seems better then running pc mark. That thing takes to damn long.

Yeah baby. So its not just my f'ing board. That makes me feel better about it There not able to calculate a non-stock multi? Waz up. What do you mean 500mhz on ram? 250x2 or 500x2? I become unstable at 4-4-4-12 980mhz. Bump timings up to 5-5-5-15 and I'm stable at ddr2 1060.
I've got the bought version of pcmark05. I just specify the ram bench. It doesn't even take 3 minutes.

500x2. First time ive got this mem to 1000. Ran pi stable but performance was crap because cpu was only 2.4 and divder on mem. It's weird it seemed stable there but when i put multi back to 7 system became unstable. So for whatever reason i can run 400x7 with mem 1:1 totally stable. If i throw in a divider to run mem @ 1000 it craps out But if i drop cpu multi to 6 and leave everything else alone it's fine. This brd is frickin strange.

 

[ntdouglas]

Dude, its us not the mobo. lol. Did you get 1000mhz at 4-4-4-10 ???
If you were at 1000mhz at 4-4-4-10 thats your problem. It ran fine at low cpu speed which I've done. It became unstable at higher cpu speed because of the tighter timings. Loosen it up. Try 5-5-5-15 . Then back down slowly. 5-5-5-12, then to 5-5-4-12, etc. I've read our boards get "tricky with d9's". "You have to fine tune mobo." I keep thinking about what mushkin told me. "We test all ram at mch 1.55v."

The timing shouldnt be a factor because the multy only affects cpu. I tried it though just so i could tell you i tried it and nope still very unstable. It makes it seem like cpu is the problem going by this information but i know the cpu will do 3.2 stable with mem 1:1.

 

[ntdouglas]

Ok, I thought it might work. What about bumping up mch by +0.30.
Was it your ram or the mch? Well I'm at 440 fsb on 8 multi for 3.52g
on cpu although I haven't ran orthos yet. 41c idle. I've been meaning to ask you this, in tat cpu 0 shows 41c and cpu 1 shows 39c. Why is 1 core running a little hotter than the other? And this is all the time, not just with this oc.

 

[rizzo]

They all do that. mine is usually like 42/45 when i'm running 3.2 or so. On the mch thing i might have tried it dont remember but it already proved it could run this speed when i used the 6x multi which should have no impact on anything else... except a bit more power consumption. The mind boggles...

 

[ntdouglas]

My shit rebooted running pcmark05 at 3.52g when I left it for 15 minutes. I think I'm going to try the +0.30 mch and fsb
thingy before I give up.

 

[rizzo]

So you cant get 9x400? Thats only a 400 bus so the brd and mem should not be a factor and gives you a 3.6oc. You should do a google for your specific brd if you havent already(read some reviews if available). The dq6 seems like it may be a lil tougher to oc in some cases. You've done well though.

 

[ntdouglas]

Thanks man. No to 9x400. I'm at 440 x8. I didn't see it but I believe my shit rebooted. I just ran pcmark again while I watched and it ran fine with highest scores to date. I'm going to run orthos now. And hold my breath. I scored higher on my ram scores at 880mhz with tight timings verses a 2.5 div at ddr2 1050 with looser timings. The ram runs faster as the cpu and fsb run faster. Very interesting. I read alot dude. Your very active tonight, I see your in my new thread!!!! Super pi 1m score 14.383.

 

[ntdouglas]

Something strange happened . I was at 426 fsb and 8multi and a 2.5 divider on ram for
ddr2 1065 orthos stable. I tried bumping it up to 428 fsb for ddr2 1070 and ram didn't like it.
Now I can't get stable beyond ddr2 1040. All settings are the same. How could I be stable at a setting and now I can't?

 

[ntdouglas]

Cleared cmos and I'm ok. ddr2 1065 and orthos stable. I'm gonna get the Ocz ram cooler. I really think that up to a certain temp the ram pukes. Cooling it will only help. Ddr2 1100 with active cooling.
