stable clocked ram remains forever?

[Chiari]

First off all im glad to find a board where we can discuss about top-performance and FSX at the same time! Have been reading since a year ago but never signed up.

The problem is that i have a p5k dlx, q6600 and 2gb crucial pc6400 400. In the past ive got the cpu to 3.0 (333x9) and ram to 1066 5-5-5-15 pretty stable.. Prime 8hrs, memtest 8hrs and not even a single reboot or bsod for about 10 months. It means all the games, apps and FSX and that was with a low-end aircooling.

Yesterday i bought a TRUE with an 110cfm fan to let the fun get more serious. Put the cpu on 3.6 (9x400), ajusted all the voltages until it get stable to boot and start prime. I didnt mess with the ram since it was fine with the soft clock (3.0). Now what i want to know, is if it was stable in the past, will it become unstable since i changed only the CPU frequency? Truly the p5k decreased the mem speed by the fault of my max cpu strap of 333, so it

sorry ive made a mistake talking about the cpu fsb strap, its on 266 and not 333. 333 only let me to choose between mem speed of 960 or 1280. For 1000 im using 266.

dram static read control, transaction booster and clock overcharging mode are all set on AUTO. All of the dram subtimings are on AUTO too.

The voltage damper is enabled and the voltages are as follow

PLL CPU: 1.50v
FSB: 1.40v
NB: 1.55v

its good to figure out that not only the core temps are good but the northbridge too. It never exceeded 43degrees on prime blend test.

your memory is going to hold you back


I am really tied up right now and do not have time to look at this but I will try to get back to it in a day or so

tnx nick, i think i got it in order

the good news are that i stablished the whole system. The main reason was that vcore wasnt enough.. Raised it to 1.50 on BIOS wich means 1.48v on overload and now everything is pretty descent. The memory is holding tight in its job, running at 1080 5-5-5-5-15 with 2.05v. Another improvement i did too was changing 9x400 to 8x450! everything is fine now

I decided then to tune those other voltages beside vcore. The weird thing was that i could set all of them to the lowest values on bios, meaning northbridge, cpu pll and fsb termination. Doesn

Sick! I give up for fsx, theres no way i can run it smooth on my pc, sadly. Its quite funny it only depends on the traffic, i can run with all sliders to the right, even autogen on 'extremely dense' and weather coverage at max, at about 30fps with 0% traffic on the airports. But if i take it to the most disgusting 5% of airliners, then the whole shit drops to 1 digit framerates on heavy hubs such as klax an kjfk. Crazy stuff.

Sorry but i wont touch this game until i have a nice ~ 5.0ghz quadcore with 8gb ddr3 and a kind of gtx350 when it comes out. ive done all that i can  :'(

I had almost the same setup as you and got excellent results. Raed the above thread - might help.
