First OC.

post #1 of 9
Thread Starter 
I can't really say that I did it, but I ran nTuner for 3 hours, wrote down the adjusted values, and changed it in the CMOS.

AMD 3200+ Venice - 2.21GHz to 2.62GHz (19%)
FSB from 201MHz to 238MHz

Memory timings (?) - tRAS: 4 tRCD: 1 tRP: 1
I have no idea what this is about.

HTT Multi stayed at 4

AGP Bus - 67MHz to 77MHz

No adjustments to voltages.

~46C testing with 3DMark06, ~39C idle.

Pre-OC 3DMark06: 3511

Post-OC 3DMark06: 3604.. +2.6%

[Note: Those scores are with the resolution set to a lower 1024x768]

Default 3DMark06 Official Score: 3271
I rank with 3700+ processors. ^^

I have a question, though. How does a 201MHz bus and a 4x multiplier give you 2.21GHz? How does a 238MHz bus and a 4x multiplier give you 2.62GHz? When I was setting this up in the BIOS, I was expecting to see 2.4GHz. Not a monstrous 2.6GHz. Don't get me wrong, that's great. But I'm not sure how stable it will be, or how much it will affect this processors life span.

Let me know if I screwed up anywhere, or if there's anything I need to check.

The HTT Multi is different to the CPU Multipier.

The CPU Multi will be @ 7 (238FSB * 7CPUMulti = 1666MHz )

The HTT Multi is to do with the FSB + the HTT (should be set at 3x) over 250FSB as the overall HTT bus speed should be under 1000Mhz

It should all be fine, get a CPU-z Varify link aswell

Thanks for the reassurance. I still don't know what all this memory timing is about. Like I said, I copied and pasted from nTuner, but they didn't give me the last number. They only gave me 3. What should the fourth one be? Right now I'm at 2.5-2-2-5.

PS- Why does my voltage fluctuate?

Apparently you can, as I've read. I changed the AGP FSB in BIOS, but I don't think it saved. nTuner says it's still 67MHz instead of 77MHz.


Edit: Loosened the timings after reading more about them, and my own RAM. 2.5-3-3-9

Your cpu has a multiplier of 11 x! It's 11 x 201 = 2.21ghz

The HT speed of an AMD cpu should always be around 1000mhz and that's why 5 x 200fsb = 1000mhz on stock

Example: 250fsb x 11 = 2750mhz
4HT x 250 fsb = 1000mhz HT link

So as I change my CPU bus, it's also my HT Speed. You don't want to go over 1000MHz on that, correct? Thus, a ceiling for your CPU clock?

HT Bus from 804MHz to 952MHz.

250MHz x 4HT would be the 1000MHz limit.

250MHz x 11 multi = 2.75GHz ceiling? Given that your CPU cooler is adequate.

Then again, you could turn both of these multis, or just your HT multi down. Forget all that I said. No ceiling.

I now understand CPU overclocking. Thanks guys! On to understanding RAM overclocking, and if it's even necessary.

CPU effects the RAM bus speed only the same amount if the RAM is set to 200MHz (DDR400) initialy.
If the RAM is set to 166MHz (DDR333) it only increases approxamately 83% of the CPU increase. That can vary slightly dependant on the multiplyer used on the CPU.
The HT or sometimes called the HTT...
It's multiplyer default is 5x, when that is multiplyed by the default CPU bus speed of 200MHz the total is 1000MHz. Most MBs start to get unstable if the HT is beyond 1080 but some can go higher and still be stable. Above 1000 does nothing for performance.
4x is usually ok up to a CPU speed of 260. If you excede that drop to a 3x.

BTW, CPU-Z should give you more RAM timings and it's handy to have

My Corsair stick only shows one speed at 200MHz. 2.5-3-3-8

My two matched Kingston sticks show 133, 166, and 200MHz.

2-2-2-6, 2.5-3-3-7, and 3-3-3-8 respectively.

On the Memory tab, it says the Frequency is at 119 MHz. Should I adjust this in the BIOS to 200MHz? Then my timings would be 3-3-3-8.

Edit: It shows 200MHz in the BIOS, but in the same page at the top, it says it's running at 100MHz o.0 My options are 200MHz, 266MHz, 333MHz, and 400MHz.

Sorry to bump, but I need an answer on that RAM frequency.
