Overclocking my 3500 x64
- Thread starter akirru
- Start date
To be honest mate... The RAM doesnt really make much difference anymore with AMD64's
I bought a pair of Corsairs XMS4400 TwinX Sticks and a Pair of the same but Platinums, and guess what? I have chucked them into a pair of Socket A PCs instead!
Dont know the exact model of your Board, Asrock Sata II ? - Dont have experience with it, but is it a clockable board?
NForce boards are the best choice if you ask me for clocking as they keep the PCI / AGP / PCIE slots locked down ( Sometimes you need to lock the AGPto 67 or the PCIE to 100 to do this ) but otherwise, you will be overclocking the bits that you dont want to.
The RAM as I said, is no worries anymore... Its rated to 200 ( 400 DDR ) so just knock the RAM down to 166 and push the CPU up a little... If oyu canfind you are going over 233 on the CPU, this will also mean that the RAM will be going over 200, so knock the RAM down to 133 and carry on!
If you start to get sily things like not running well, then up the CPUs volts a notch and re-try.
Keeping your eyes on the temps, you will find that as long as the board is ok, and will let you clock the CPU, the CPU will clock at least something.
Like I said, I dont know about this particular board.
Best clockign boards to get, are MSI or DFI.... NForce 3 or 4 chipsets yeah?

Not a problem.
Here you are ... Thisis what do with some of my PCs
These ones run at 200FSB stock, so the basics will be the same as yours.
( Assuming I have just cleared the CMOS )
1 - Knock the AGP to 67 or the PCIE, set to 100
2 - Set the RAM, to 166
3 - Set the CPU FSB to 230
4 - Set the HTT to 4x
5 - Set the CPU to 1.5
These are as simple as they can be... They all work on my main boards.
My main AMD Boards are all NForce 3 or 4
These boards are:-
MSI Neo4-F & X2 4400
MSI Neo2-P & x2 3800
MSI Neo2-P & Winchester 3200
DFI LanParty UT 250GB & Newcastle 3000
And will let all of these run at 230 in just a few touches of the settings.
They all run higher, but some of these ( x2 4400 and the Newcastle ) require a little more TLC to take them further... This way is a tried and tested way to get 230FSB without any real work.
Ok, so describe what each bit does...
1 - Knock the AGP to 67 or the PCIE, set to 100
The PCI bus runs at 33.3Mhz. The AGP at 66.6. If your PC has PCIE instead of AGP, then that runs at 100.
I wont go into too much details, as better info can be had in a million wab pages, but we MUST make sure, that we DO NOT overclock the PCI / AGP / PCIE ports... If your board starts to over clock them, then you can say good bye to any kind of overclocking. If you can set the PCI / AGP /PCIE to anything, then there is a good chance it will lock them.
2 - Set the RAM, to 166
Because our ram is maxed out at 200, if we clock the CPU to say 210, then the RAM will also go up by 10 too, making the RAM run at 210 also.
Now, if we knock the RAM down to 166, then once we have gone up by 10, the RAM will also go up by 10, and in this case, it will be running at 176... and so, we are still running the RAM below its max of 200 arent we?
Of course, we then have a sort of limit of 234FSB on the CPU, but if we can go past that, then all we have to do, is start the RAM at 133 instead!
Nice and easy yeah?
3 - Set the CPU FSB to 230
Of course, thats what I do, because I know they do it wih no problems. Your CPU will too, butwill your Motherboard let you?
I suggest going up in much smaller jumps... start at say 205 first, and see how it goes, then 210, then 215 and so on... Its always better to be carefull especially if its your first try at clocking.
4 - Set the HTT to 4x
Now, with AMD64 CPUs, apparently, there is no such thing as an FSB anymore? - its HTT.
This, I will tell you now, is thick!
You have to keep the HTT below 2000
The HTT is an FSB Multiplier... In the BIOS there will be an option to adjust this. with a FSB of 200, the HTT will be 5x or, in other words HTTxFSB / 5x200 = 1000
You can run it well below, but dont go over.
As soon as you start to clock, set it to 4x
To be honest though mate... I have had it at 1x, 2x, 3x, 4x and 5x and not noticed any drop in performance or stabiliy - EVER!
But, better to go with those who really know!
5 - Set the CPU to 1.5
This is the VOLTS.
I think you will probably get away with running a fair bit higher than 200FSB with the standard volts actually, again, I just set it to 1.5 cos (a) I got good cooling (b) I cant be bothered to faff about with 1.475 for 245FSB or 1.45 for some other FSB... 1.5 lets me go to 250FSB and I am happy there.
Oh, by the way, I just mentioned that I can go to 250FSB, and at that, my HT is at 4x
I can go higher with all these CPUs but I have no need... 4x250 is 1000 and 1000 doubled is 2000 - gets that HT spot on to 2000. As soon as I go to 251FSB or above, it means tat I would need a 3xHTT wouldnt it?
Listen. I am waffling now, so have a read up on things and NEVER take what I say as the gospel. What works for me, might not work for you... As with any kind of over-clocking, you will always run the risk of frying your PC, and if you do that, its no one elses fauly but your own.
Read what I say, but verify it first, and make sure you are happy before you do anything.
Good luck.

Heya I know this topic is a little old but using your advice ive done my first CPU overclock ever...Im now at 2.42Ghz, but when i try to raise my CPU FSB higher than 220 i tihnk im on, its just crashes on Windows loading bit, is this becuase i need to put my Voltage to 1.5 and then i will be able to go higher. Also i couldnt find anything to do with HHT in my BIOS...
Oh and my temps are still pretty low, 36Oc Idle and 44Oc Full load...

Not bad temps or overflock for your first try! In regards to the HTT, it might be shown as 'LDT multiplier'. Things can start to go funny if your HTT frequency/speed is more than 1000MHz so as said previously, you should try dropping it to 4 i.e. 4 x 220 = 880MHz
Its always better to up the FSB.
What CPU is it? Most CPUs there days are locked down to whatever the Multiplier is.
I remember with my good old XP17 ( Still that little darling - never get rid its such a speed demon ) but that would let me play with anythign on it, and to stupid speeds too!
I was able to run the Multiplier all the way to 18, and the FSB was fine till about the 255ish marker but again, I was able to play at higher with various settings at various levels of success ( And failure ) and when I finally broke the 3Ghz marker, my FSB was really low... 216 I think it was?
However, when I was tryign to get the FSB higher, keeping the Multi as low as possible, I never quite reached 3Ghz, but the PC itself was far, far faster than it was at 3Ghz.
Not sure of the exact figures I was on, I could make somethign up, but cant be arsed right now, btu it showed me that high FSB is better than high Multi.
I suppose in a slighty similar way, I can compare my P4 against my Conroe...
My P4 is 18x240 - best I have had is 18x266
My conroe is only 7x480 - best I have had is 7x500
and its just walking all over the P4 yet the actual end speed in MHZ is way lower. Bad comparison I know, but there you go... Its 7AM and not my time at all.

Well atm its stuck on 11x220, any higher and its doesnt like it, im just thinking that the mobo or the CPU is just crap for overclcoking, i never bought this hardware wanting to o/c and now ive had the guts to do it ive never realised how easy it was (just abit risky). Im still really low temp and its the hardware thats restricting me. Oh well its all experiance for the future i guess...
I might try 12x200 and see if it lets me do that (logically, its the exact same as what i have now...), should do and then just knock FSB up 1 at a time to see the max...

Yeah, thats cool.
You have a Theoretical max FSB of 220 ( Trust me, it will go higher, but lets stay there for now ) and so, if you can up the Multi, then thats great... You iwll then be able to take the FSB up to the 220 too, so, if you do indeed get 12x multi then thats 12x220 you know you can acheive... In theory... Which could be 2.6Ghz, or its just over actually... 2.64 in fact.
What CPU are you using?

12 x 220 on a 166 divider will mean that your RAM will be running slower than it's rated to. You'd need to have your FSB @ 240 MHz for your RAM to be running at it's rated speed whilst on a 166 divider. That would give you as follows: 240/6 * 5 = 200 MHz RAM.
If you've already put a lot of volts through the chip & can't get anywhere then the problem may lie elsewhere, check cpuz to see if the RAM timings are set as per the SPD tab.
