I am trying to work out what my X2 4600 is capable of doing

I have got an Asus A8N SLi SE mobo and 2 gig of DDR3200 ram. I am working on the assumption that I can leave the multiplier alone and just ramp up the FSB a few notches and adjust vcore as needed to ensure stability.

It would be helpful if some of you more experienced overclockers could post your clocks and setting here e.g FSB/Dividers/Vcores for an X2 4600 so I have got a better idea of the ballpark I should be headed for before I blow something up.

I am doing this on air cooling only so I don't think I should be considering any vocres above 1.45 ? (or can I go higher ? )
 
Well I have the AM2 version of the chip and get 2760MHz max stable out of it, 2.8GHz if I work it correctly but it isn't fully stable.

I have to clock mine as so;

FSB - 299Mhz
Multi - 12x
HT - 4x
Vcore - 1.45v

I'm not sure that there is much difference between our two chips, but as far as I know 939s seem to be capable of getting better clocks than the AM2s.

Hope that helps, even if it is only a little. :)

You can't have your FSB@299Mhz & the multi x12 mate,that would give you 3.5Ghz :eek: If you do have it @299 you need to drop the HTT down to x3,that may help your stability problems ;)

Why not try this as a starting point

FSB-250
HTT x4
Multi x10
Vcore -1.45-1.5v although you may need with less/more.Depending on cooling temps
Ram 166 divider

Once you start going above 250 FSB lower the HTT to x3 & you may have to lower the ram divider as well.Never used that mobo,so i'm not familiar with what divider options you have

2760 is still the max it'll do, I tried fiddling with all different settings and they are all naff :rolleyes:

I have at the moment put it back to standard...I've forgotten why.

What sort of ram voltage should I put my ram on, it's 4-4-4-12 corsair ram, just thinking that on auto voltage it probably isn't the best idea.

I did get the bios to tell me I had about 3.2Ghz when I had a low clock and a low fsb, not too sure what was wrong with the bios's readout, but it wouldn't actually post, it'd beep at me, then let me get into bios to change it.

Back on topic;

Start with small (5mhz) increases on the FSB and when the ram starts to be looking a little shadey, drop the divider thing down one to allow for higher cpu clocks. Also keep an eye on the 'HT Link' normally you want to keep it below 1000mhz, mine can go up to 1100mhz though.

I have gone into the bios and under the "jumperFree" configuration i get the following options

Overclock profile ( I set this to manual so I can make the changes my self)
CPU frequency - I have set this to 220 (going for a small OC first)
PCI express Clock - 100mhz
DDR voltage - choice of 2.6-2.9v or auto
CPU multiplier x 12
CPU voltage - I set to 1.45
PCI synchronization clock ? no idea what to do with this, I get 3 choices of Auto, To CPU or 33.3mhz - any help with this one would be welcome :)

Under dram configurations I have the following options

Timing mode - Manual
Memclock index value - currently set at 400mhz
CAS latency - 3
Min RAS active time - 8T
RAS to CAS delay - 3T
Row precharge time - 3T
Row cycle time - 11T
Row refresh cyc time - 14T
Read to write time 5T
Write recovery time - 3T
1T/2T Mem Timing - 2T
S/W DRAM over 4g remapping - enabled
H/W DRAM over 4g remapping - enabled

Could I just set the timing mode to manual and let it adjust itself to the CP frequencies ?

CPU frequency - I have set this to 220 (going for a small OC first)Sensible, start with low and work up 5mhz at a time
PCI express Clock - 100mhz Leave on auto
DDR voltage - choice of 2.6-2.9v or auto Depends on the manufacturer's stated voltage of your DDR
CPU multiplier x 12That'll be fine
CPU voltage - I set to 1.45Mine is 1.40 stock, so 1.45 will be fine, especially as I can get 2.4Ghz to 2.7Ghz on 1.45v
PCI synchronization clock ? no idea what to do with this, I get 3 choices of Auto, To CPU or 33.3mhz - any help with this one would be welcome :)Leave as is/auto

Under dram configurations I have the following optionsI'd use 'CPU config > DRAM settings' (or something like that) which will enable you to change the main timings that get used without messing up others.

...

Could I just set the timing mode to manual and let it adjust itself to the CP frequencies ? If you set it to manual you should change settings, if you aren't going to then leave on auto.

Hope that helps a bit. :)

ok tried 220 x 12 @1.45v and it posted fine. I think processor might be running a little hot though as the idle temps are being reported as 44.

the hyperthreading is 1100 and it seems to be ok.

Will run a few tests to see how it performs

Pity ,it would have been some oc :p

Why not drop your multi & ramp up your fsb a bit mate ;)

and what would that accomplish? with a64 there is no fsb, its the htt. and it works differently to old type fsb's. sacrificing base speed for more htt is just plain stupid.

What are you on about :confused: :confused: Where have i told anyone to sacrifice thier base speed

Where did i say that,i said drop the cpu multi & up the fsb

Quote from the oc guide-(though HT provides most of the functions previously associated with the FSB, the CPU clockspeed is still manipulated by the FSB option in the BIOS). So you still need the change the FSB in the bios

If thats the case,why have you got your A64 @300fsb instead of default then if its not any faster

The LDT/HTT still needs to be kept around 1000,so if your fsb is @ 250 you then need to drop the LDT/HTT to x4,so on & so forth

e.g. 240 x10 is still faster than 200x12

I have my 4400 set @ 300 x 9 just now & its faster than having it @ 245x11 :rolleyes: Mate....i've been overclocking cpu's for years ;)
