My FSB is currently at 250 giving me a nice 2.5Ghz Athlon 64 X2 3800. My DDR is 1:1 (400) at 250 @ 2.5-3-3-6.
Is it possible to run my DDR at higher speeds, such as 433, 466, or even 500?
What speeds would that make it run at? For example, if I ran my DDR at 433, would it be running at 270 (with my CPU still at 250)? I have Geil ONE TCCD DDR400 which also runs at DDR600 @ 3-4-4-8 so I was wondering if I could run my CPU at 250 and my DDR at 300.
I'm at work so I can't test it out for another 8 hours but any insight would be appreciated by the time I get home!
My CPU's limit is 2.55Ghz stable. No matter what combination of FSB, voltage, multiplier, and RAM timings, it won't do 2.6Ghz.
My mobo's gone up to 290+mhz but it didn't do any good because, like I said, with any combination, my CPU wouldn't do 2.6Ghz. I have a Zalman 7000CU cooler, soon to be exchanged for a Thermalright Xp-120 so maybe I'll hit 2.6 or 2.7 later this week.
Yeah, I've had my HT at 4 and 3. DDR at 400 and 333. timings loosened all the way to 3-4-4-8. I can run the FSB all the way up to 290+ but every time I get my CPU at 2.6 (regardless of the combination to get there) it's not stable. Well, it boots into windows but Prime 95 lasts about 5 minutes. Voltage has been up to 1.55V. Don't want to go any higher. Need the computer to do 3D work. Don't want to risk anything
My temps tipically at 2.5Ghz are 32 idle and anywhere from 48-54 load
yeah, I'm more than happy at 2.5Ghz. I just gotta get my temps down. The only way I can get it up to 54 degrees is if I run Prime 95 and CPU burn-in simultaneously. By themselves (or when I game/render 3d) it doesn't get above 48. I'd like to keep it below 48 no matter how many things I have running though. Can't wait for the xp-120. Oh, and my NV5 for my 7800 GT is coming in this week as well. Between the two of them, my temps should drop a bit.
Oh, check out my thread and you'll see why I'm happy
Thanks for trying. My CPU is stubborn, but I love it just the same
In the past I rushed to buy a huge fic MB with 1000 jumpers supposedly allowing me to run the RAMs and CPU at different
speeds. No other settings would work at all for more than a few minutes, however, only 1:1 ratios would succeed. And even todaymost motherboards are so completely un-buffered that they need to be run at 1:1 ratios.
I have a time getting mine to 1:1 and then I have to guess the ram numbers
the SPDs I know from CPUZ but the timings I want to have detected somehow
the fact is you should run one step higher speed then the clock speed you are running at
even at the exact speeds at the SPD the BIOSs seem to mess up what is the way to see all of their settings
The rightmark people have something that sometimes works, you can set the settings and perhaps you will
be stable and even benchmark at better rates and feel right to change your BIOS timings.
