Sup Guys.

I just build this rig 2 weeks ago.

Fortron BlueStorm 500Watt
AMD Athlon64 3700+
OCZ EL Platinum Rev2 TCCD 2-2-2-5
DFI Lanparty UT NF4 Ultra-D
EVGA Geforce 7800GT w/copper heatsink
Pioneer DVD-Burner
Zalman CNPS7700-Cu



Currently running at: 1:1 ratio

CPU : 300 x 9 = 2700 mhz @ 1.425 Volt
Ram timing: 2.5-4-3-7 @ 2.9 Volt


Genie BIOS Settings:

FSB Bus Frequency - 300
LDT/FSB Frequency Ration - Auto
CPU/FSB Frequency Ratio - 9
PCI eXpress Frequency - 100Mhz

CPU VID StartUp Value - StartUp

CPU VID Control - 1.425v
CPU VID Special Control - auto
LDT Voltage Control - 1.20v
Chip Set Voltage Control - 1.50v
DRAM Voltage Control - 2.9v

Temperatue: idle 27 celcius, load 37-39 celcius.

I already tried 240 x 12 = 2600 mhz at timing of 2-3-3-5 and its stable. CPU volt is at default, ram is at 2.9 volt.

what do u think? should I go for 2700 or 2600 on tight timing. how can I achieve 2800mhz?

Also how is my Temperature?

CPU - idle 27-29 celcius, load or after playing quake 4 or Counter-strike 37-39 celcius
PWMIC - idle 37celcius, load 39-40 celcius
Chipset: 48 celcius, max I see is 49 celcius?

what is the safest temperature on these chip?

UPDATE: I just read some threads, and they say something about using a divider to get my memory on tight timing. Can I do 2800mhz on tighter timing? like 2-2-2-7?

Hey I just disable Thermal Throtting awhile ago and my temp is drop considerably.
I mean it always around 27-29 celcius, not fluctuating toward 38 anymore.

Usually the temp reach 38 celcius and my fan start to sped up to full speed cause I set it in the BIOS temp > 38, full fan speed. Is there anything wrong with it?

I have the same CPU and ram and I run it

255x11=2805 1.55v

with the DDR333/166 divider which runs my ram at 208mhz 2-2-2-7 at 2.8v

1. Don't leave your LDT multiplier on auto. Thats fine if you aren't overclocking, but once you start overclocking you need to lower the LDT multiplier as going above 1000mhz HTT causes instablility. Change it to 4x for up to 250mhz FSB, above that go to 3x.

2. Using a mem divider will help you get a higher CPU overclock. A64's are not bandwidth starved, so using a divider isn't going to have a major impact on performance, while it will keep you from being memory limited in your overclock.

3. As for your temps, they are very good. I would worry if you started getting to around 60c.

Its been shown in reviews, Athlons thrive on tighter timings. I would venture to say that 2600 is faster. And those chips top out around 2700 anyway.

What does your CPU max out at at certain voltages? I can get 2805MHz at about 1.435V on my 3700+.

UPDATE

RIGHT now I'm running 280 x 10 @ 1.45v on a divider 5/6, DRAM 2-3-3-7 @ 2.8v. Pass SuperPi 32M on 27m 266s. STable

is it better? or worst cause its on a divider of 5/6.

Please great ELDERS, should I keep this or go back to 240 x 11, 1:1, 2-3-3-5 2.8v

And is 2.9v on TCCD too much?

So your RAM is running at about 232MHz. 2.9V is usually safe on almost all RAM. Push it to 2.9V, then see if you can't get tighter timings. Also, the forth number in the x-x-x-x thing makes very little performance difference. Around 10 is supposedly ideal, but don't quote me on that.

Ya the ram is running on 233 at 2.8v, timing of 2-3-3-7, I will try 2-2-2-7 or 2-2-2-8 at 2.9v.

So 2.9v is really safe? Smarguardian show 2.9v in red meaning it is not safe?

So are u saying running on a divider with tight timing is better than running on 240x11 without divider but at 2-3-3-5? I'm really confused

Your current settings are much better than the 240x11 settings. You've got 200mhz more CPU with the same ram speed and latencies. Even if you had to sacrifice ram speed the 200mhz CPU increase would be worth it, but in your case with ram virtually the same its a no brainer.

Don't worry too much about the mem divider, just use whichever one is needed to keep ram at a stable speed with your max HTT overclock. The best range on the last figure is usually 5-8 but don't sweat that too much either, I leave mine at 7.

Ok I'm happy now. I have three option.

1. 300 x 9 @ 1.425v, 1:1 ratio, Ram timing: 2.5-4-3-7 @ 2.9 Volt

2. 240 x 11 @ default volt, 1:1 ratio, Ram timing: 2-3-3-5 @ 2.9 Volt

3. 280 x 10 @ 1.45v, 5:6 ratio, Ram timing: 2-3-3-7 @ 2.8v

Which one should I go for?

Dooh! The one with the higest CPU clock >smacks head<

Not a very difficult concept, the bigger the number the better.
Ram speed means nothing, ram latency means little.

Sorry Master GuitarDaddy, bow bow bow !!!

haha ya I'm using 280 x 10 @ 1.5v CPU VID 104%, 5:6 ratio, Ram timing: 2-3-3-7 @ 2.8v

I will test Prime95 tonight.

Go with number 3. The CPU speed is the most important.
