Hi all,

I just bought my first AMD system and it's AMD X2 3800+ and I want to OC my CPU to 2.4 Ghz.

I have read the OC guide but still don't really know what to set.

Looking at my target of 2.4 Ghz, can someone who is familiar with MSI K8N Neo4 Platinum mb tell me the optimal setting?

I am using value ram and 420 W OCZ power supply. My CPU cooler is a Zalman.

The overclocking page of the MSI bios look like this:

CELL MENU:

High performance mode [Manual]
Aggressive timing [Disabled]
Dymanic Overclocking [Disable]
Adjust CPU FSB Frequency [?]
HT Frequency [?x]
HT Width [down 16 up 16]
CPU Spread Spectrum [Center Spread]
SATA Spread Spectrum [Disabled]
PCIE Spread Spectrum [Disabled]
PCIE CLock [100Mhz]
SSE/SSE2 Instructions [Enabled]
Cool 'n' Quiet [Disabled]
Adjust CPU Ratio [Startup]
Adjust CPU VID [Startup]
CPU Voltage [?]
Memory Voltage [?]
NF4 Voltage [?]

High performance mode [Manual]
Aggressive timing [Disabled]
Dymanic Overclocking [Disable]
Adjust CPU FSB Frequency [240]
HT Frequency [4x]
HT Width [down 16 up 16]
CPU Spread Spectrum [Center Spread]
SATA Spread Spectrum [Disabled]
PCIE Spread Spectrum [Disabled]
PCIE CLock [100Mhz]
SSE/SSE2 Instructions [Enabled]
Cool 'n' Quiet [Disabled]
Adjust CPU Ratio [10x]
Adjust CPU VID [Startup] - Leave your vcore at 1.4V, & raise in small increments if you cannot get stable at 2.4GHz (stay below 1.5V to be safe)
CPU Voltage [?] - IIRC, this is for adding additional vcore by percentage. Don't worry about this for now, unless your mobo is undervolting
Memory Voltage [2.7]
NF4 Voltage [Auto]


Also, you may need to lower your RAM speed (use a divider) if you have PC3200.
I would go into RAM settings & set the divider for 166, assuming you have PC3200 memory.
I know there's a ton of RAM options too on that mobo, just leave them auto for now.

Hi there, thanks a bunch for your assistance. Have few more questions.

How do HT 4X and FSB 240 Mhz add up to 2.4 Ghz?

Yes, I am using PC3200 and therefore need to set the divider to 166.

Which screen should I go to input 166? Is it the DRAM configuration?

Do I set Timing mode [Manual]

And next change Memclock Index Value Mhz [166] ?

On the same screen, do I have to change any other value?

The 4x, means that your HTT will be at 960 (separate from FSB). FSB x multi = cpu speed, HTT x LDT(4x) = Hypertransport speed (how it talks to the motherboard)

N7 has the right idea with the settings. Make sure you go with something other than stock cooling if you want 2.4 or better. I am at 1.45v (I think it was 8.3% or something) at 257, and not sure the LDT, I think I lft it at 4x, for a total currently of 2570.

Mark about covered that :thumbsup:

Keep us posted on how it fares, aight? :)

Whoa, Mark, i thought you had your 4400+ @ 2.7 GHz? :confused:
Your sig states that your 3800+ > 4400+ eh?

Here's my setup. Same board, but I have the 4400+. The only real difference should be the multiplier/CPU.

High performance mode [Manual]
Aggressive timing [Disabled]
Dymanic Overclocking [Disable]
Adjust CPU FSB Frequency [235]
HT Frequency [4]
HT Width [down 16 up 16]
CPU Spread Spectrum [Center Spread]
SATA Spread Spectrum [Disabled]
PCIE Spread Spectrum [Disabled]
PCIE CLock [100Mhz]
SSE/SSE2 Instructions [Enabled]
Cool 'n' Quiet [Disabled]
Adjust CPU Ratio [11]
Adjust CPU VID [+0.10V]
CPU Voltage [1.45V]
Memory Voltage [2.8V]
NF4 Voltage [AUTO]

Yes, actually at the moment, it is a few mhz higher. 4400+@2552, 3800+@2570, but the 4400+ is dual channel@1:1, and the 3800+ is single channel with a 166 divider. I think the 4400+ would bench higher based on all that. And the 3800+ is at 2T, where the 4400+ is 1T.

After I OC from 2 Ghz to 2.4 Ghz, my CPU idle temp increased from 34 'C to 41 'C, is it normal?

This is the second day of my PC and I think my AS5 thermal has not been burnt in yet.

Should I stay OC at this temp or should I let my system run for a few days first?
