I'm using

Athlon 64 3200+ NewCastle socket 754 + CoolerMaster Hyper 6
2x512MB Corsair XMS PC3200 3-3-3-8 @ DIMM 1 n 3
DFI Lanparty nForce 3 250gb UT
Seagate 120GB 7200rpm ATA 133
ASUS FX 5700 256 MB
Creative Blaster Live ! 24bit 7.1
CoolerMaster eXtreme Power 380W Dual

Because I've just started OCing so...I really need help from anyone who had experience in OCing !!!

I wanna OC my CPU and Ram....Where can I start ?? How can I OC ???

Please help me !!!

Please Post in detail cause I'm just beginer


thanks alot

Ok, i'm not quite sure about how 754's work, but they can't be too different

Also, i'm fairly new to this too, so you might want to wait after what i've said for other people to correct me, I must have made a couple of mistakes.

Ok first off, check your HTT is at least 4x, then set your memory to 2T command rate, and up your memory voltage to 2.7 (Be careful though! read some tutorials if you're unsure, I don't want the blame if you fry your chips!)
Now up your FSB by 2 Mhz each time, restart and boot into windows after each increment. Then this should work until about 215 with your setup. When things start to crash or if your computer bleeps at you, then set it a tad lower so you don't cause much damage. After this what you want to do is set a divider up for your memory, so in the memory section put an artificial memory limiter (I think that's what it's called in your bios) for 166Mhz. Now you can continue to overclock for a bit longer.

One thing I am worried about is your PSU... 380W good enough? How good is it?

I'll say the rest about voltages later. there's alot of info there! So please, if you have learned from this, remember how the REP system works

Thanks for ur helping!!!

However, there some word I dun understand such as :

"set your memory to 2T command rate" ?

"set a divider up for your memory" ?

"artificial memory limiter"

I'll try my best to explain


ok, in the memory section, there will be a setting called "command rate", this will be possibly set to "Auto". You need to get it to "2T".

A divider, simply means that your memory is running slower than your cpu, but you need to tell it how much slower, by selecting "166"

Artificial memory limiter, is another name for a divider (I think!)

Your o/c will not be as good as a 939 because the 754 is built on the 130nm hence this creates alot more heat than the 90nm 939 .Just keep goin by increasing the fsb by 5mhz at a time then when you reach the wall up the v-core a notch ..But knock the htt down to 3 if the fsb goes close 1000mhz good luck

Forget all about hte 2t command rate keep it a 1t i doubt if you will exceed the confines of 1t

In DFI Lanparty nF3 250gb UT BIOS, the HTT is "LDT/FSB ratio" or "CPU/FSB ratio".

what different between them ???

thx for helping

LDT/FSB is your htt control knock it down to x3 this give a more stable o/c .TThe other one is your cpu fsb which is what you want to increase by 5 mhz

I've just OC but I wonder which is better:

1/ FSB:215MHz
Mul: x11
---->CPU: 2.36 GHz
FSB/DDR : 1/1 --->DDRam:215 MHz ( 3-3-3-8)
LDT/FSB : x4 ----> HTT : 1720 MHZ

2/FSB:225MHz
Mul: x10
---->CPU: 2.25GHz
FSB/DDR : 10/9 --->DDRam:204 MHz ( 2.5-3-3-7)
LDT/FSB : x4 ----> HTT : 1800 MHZ

3/FSB:260MHz
Mul: x9
---->CPU: 2.34 GHz
FSB/DDR (memory divider) :200/166 MHz --->DDRam:212MHz (CAS: not test)
LDT/FSB : x3 ----> HTT : 1560 MHZ

My RAm is Corsair XMS 2x512MB

I've just OC my

CPU (Athlon 64 3200+ NewCastle) stock 2.2GH
PC3200 2x512MB Corsair XMS (3-3-3-8-12-16)
PSU : eXtreme Power 380W Dual CoolerMaster

the OC detail is

1/ FSB:220MHz
LDT/FSB : x3 ---->HTT = 220x3x2 =1320MHz
CPU/FSB: x10---->CPU : 2.2GHz
DDR/FSB : 9/10 ----> DDR: 200MHz
CAS latency ( 2.5-3-3-7-11-16) CPU-Z

CPU temp from 49-51 in the beggining then 42-45 at the end of OCCT test

This system passed the OCCT Stability TEST

IS this the best OC I can have ???

...before this, I OC like this

2/ FSB:215MHz
LDT/FSB : x4 ---->HTT = 215x4x2 =1720MHz
CPU/FSB: x11---->CPU : 2.36GHz
DDR/FSB : 1/1 ----> DDR: 215MHz
CAS latency ( 3-3-3-8-12-16) (same as stock )CPU-Z

But..I didn't test the Stability by OCCT.... !!!

I'm using the number 1 (FSB:220)

THEN... I have few questions ....

Why the CAS latency of RAM didn't change when FSB at 215MHz. When I set FSB to 220 MHz , the CAS automatically changed (although I kept it at "AUTO" ) ???

I wonder which is better (1 or 2) ??? or can I OC more ???

When I keep using the (numer 1) is it good for my CPU and RAM ?

When the HTT down to 1320MHz, does it effect to the speed of my com. ?

My CPU has stock speed @ 2.2 GHz. When I OC like (number 1) does CPU run faster ??? is the CAS latency important ??

Thanks for answer

Ok, first determine what chips your Corsair XMS uses.
Look on the sticker on the heatspreaders and look up the suffix (C2, XL, LL, etc.) and the revision number.

-XMS-PC3200C2 Rev1.0 (2-3-3-6-1T) --chip--> Winbond CH-5
-XMS-PC3200C2 Rev1.1/2.1 (2-3-3-6-1T) --chip--> Winbond BH-6
-XMS-PC3200C2 Rev1.2/2.2 (2-3-3-6-1T) --chip--> Winbond CH-6
-XMS-PC3200C2 Rev1.3 (2-2-2-5-1T) --chip--> Winbond UTT ?
-XMS-PC3200C2 Rev1.4 (2-2-2-5-1T) --chip--> Mosel Vitelic 5ns ~ Brainpower PCB
-XMS-PC3200C2 Rev1.5 (2-2-2-5-1T) --chip--> Winbond New BH-5 ~ Brainpower PCB
-XMS-PC3200C2 Rev1.6 (2-2-2-5-1T) --chip--> Winbond UTT ~ Brainpower PCB
-XMS-PC3200C2 Rev1.7 (2-2-2-5-1T) --chip--> Winbond New BH-5\\UTT ~ Brainpower PCB ?
-XMS-PC3200C2 Rev3.1 (2-3-3-6-1T) --chip--> Infineon B-5
-XMS-PC3200C2 Rev4.1 (2-3-3-6-1T) --chip--> Samsung TCCD
-XMS-PC3200C2 Rev4.2 (2-3-3-6-1T) --chip--> Samsung TCCD & TCC5
-XMS-PC3200C2 Rev4.3 (2-3-3-6-1T) --chip--> Samsung TCCD & TCC5 (Rev. F) ~ Brainpower PCB
-XMS-PC3200C2 Rev5.1/6.1 (2-3-3-6-1T) --chip--> Mosel Vitelic 5ns
-XMS-PC3200LL Rev1.1/2.1 (2-2-2-6-1T) --chip--> Winbond BH-5
-XMS-PC3200LL Rev1.2/2.2 (2-3-2-6-1T) --chip--> Winbond CH-5
-XMS-PC3200LL Rev3.1 (2-3-2-6-1T) --chip--> Infineon B-5
-XMS-PC3200XL/XLPT Rev1.1 (2-2-2-5-1T) --chip--> Samsung TCCD
-XMS-PC3200XL/XLPT Rev1.2 (2-2-2-5-1T) --chip--> Samsung TCCD ~ Brainpower PCB

Then tell us what chip type you have and how to proceed from there.

Thanks so much

After check my RAM, this's what I got : XMS3200 v5.2 0546096-4
XMS 512MB 400MHz 3.3.3.8



That photos show what I OCed :

LDT/FSB :x4

P/S: I dun know how to share photo so..I use Yahoo Photo

Set your divider to 166 that will give you soome room then put your ram at fsb 250, ht at 3x, vcore at 1.6 ram at 2.65 or 2.7 and see if it posts that should give you atleast 2.5ghz
