cant get passed 2.6 ghz on my CP(AMD 64 3200 venice)

[bloodwolf808]

I think something might be defective. My cpu can boot but it requires high voltages. For example I got it to run at 2.6 ghz 100% stable at 1.67 volts. Vet Ive seen others get theirs to 2.7 ghz at 1.52 volts? Does anyone know whats wrong???

Try dropping the multiplier to x10. At x11, I could never get mine past 235-240 EVER. At x10 I ran mine 2.7-2.72GHx stable 24/7. Every processor , board, and memory kit is different.....
CPU...... drop the multi to x10
HTT.......leave it at x3
FSB.......260 (and work your way up slowly from there)
memory...loosen up the timings, and raise the voltage to 2.9 or so
voltages set the processor voltages to these.....1.425, 1.425 and 110%
These are by no means the "end all" you will have to tinker quite a bit to find the perfect settings.
What BIOS are you using? That has an impact as well. I recommend the 623-3 BIOS (latest official), but the fixed 704-2 BIOS modded by "Big Toe" is supposed to work very well too.

My friend said my Cpu probaly juist cannot overclock well. He said some chips can overclock easily paste 3.2 ghz and some just doesnt do well.

trust me, you need to drop the multi on that processor.....you are not going to scale very high at the default multi of 11. You should have no trouble hitting 2.6-2.7 with it, but the tops uyou'll see at x11 are 230-240. If you drop the multi to 10, you should also be able to get where you want to be with 1.49 to 1.525 vcore.

2.7Ghz, took some volts but runnin stable, temps are acceptable as well. Ran prime for 8 hours, but had to get my bf2 on... no point in oc'ing if you can't have fun with it!

[LVCapo]

well there you go. Congratulations and have fun. I would recommend you to keep toying with different BIOS settings. My 3500+ ran perfectly at 2.7 GHz (270x10) with 1.562 volts running through it.....but regardless, it seems you have the right idea about things and were able to get where you wanted to be.

capper,

Thanks... After a nice burn in, i can run 2.7 at a tenth less volt and 3c less as well!!! Hopefully bloodwolf808 will have the same success.

Thats a great OC way to be

@bloodwolf808, I suggest testing out each componantly individualy to see what is limiting you. First, set a very low cpu multiplier, and a really low ram divider (such as 1/2) and see hot far the HTT will scale. Next, see how far up you can scale with your ram at 1:1. You will not be able to max out your componants if you don't know what the limiting factor is.

(CPU-Z reports the voltage incorrectly, its actualy 1.5v)

The OC I decided to use for every-day: http://home.earthlink.net/~eckyx3/woot.JPG
(CPU-Z reports the voltage correctly there, using a later version)

Has anyone run their Venice over 1.6v for a while - like over 6 months? My Silent Tower has no issues keeping it at 45c even at 1.65v, does that mean I can get away with it?

[infinitevalence]

I ran my winchester at 1.65 for the last 6 mths, and it just died on me, not sure yet what the problem is so im not quite ready to say its the cpu it could be psu related.

Any idea why my initial and Loop1 times would be faster but then your machine overtakes mine?

.453s Init
1.984s Loop1
3.719s Loop2

34.406s Pi to 1M

what are your memory timings?

[gvblake22]

For some reason i cannot get to 250 FSB to boot up. My multiplier is currently at 11x. Im still not sure why its not working I even got the voltage up to 1.7 which is the max I will go. Is there a certain RAM timings i should use(Im currently at 2-3-2-6 OCZ 512x2 dual channel).

HTT=x3
Multiplier=x11
LDT voltage=auto
Max FSB I got to boot=240
cpu voltage=1.7v

Have you tried running memtest yet? 240mhz with RAM timings at 2-3-2-6 is pretty impressive actually. What EXACT model is your OCZ RAM? I would be willing to bet money you just need to loosen the RAM timings or run it on a divider to boot any higher. The exact settings for the RAM will depend on the actual model of the RAM and the chips it was manufactured on. You could try 2.5-3-3-7 or 3-3-3-7 or even 3-4-4-7. You could also try bumping up the RAM voltage a tid bit if you find you need that extra boost to get it stable.
But yeah, try some extensive testing with Memtest86+ and changing the RAM timings and/or voltage to see if your RAM is the one crapping out on ya. If so, then you'll have to run it at a divider so your RAM runs slower than the HTT bus and your CPU. But don't worry, it really doesn't affect performance too much.

EDIT: CRAP!! LOL, I did not realize this thread had two pages, hahahaha....

i am running pc4000 memory, with 3-3-3-7 as timings and 1:1 ratio... While i dont know what each timing does, i do know that as you oc your ram, you need to loosen the timings a bit. Luckily, i have a season'd veteran of a friend that helps me with my pc stuff, when its to complicated to just guess...

Try and go for 2.8GHz. Im a 2.8 stable right now and will be going for 2.9 all on air. Hope all goes well.
