Hi there,
I recently brought a 4800+ x2 to fit in mt asus a8n sli premium motherboard.
Im a noob at overclocking so would like to know if the on board ai overclocking prog is any good and how good is the standard amd fan?

Thanks
 
What air cooling is the best and what can i clock the cpu to with this?
Are there any good cpu progs that i need to monitor my cpu?
 
last ones now floating around a few retailers are not that good. you will need to put a lot of volts into it to get best clocks . the one i picked up 2 weeks back tops out at 2760 won`t go higher on air just to hot. will be removing the cap weekend should see me up to around 2800 area but not something you should do unless your not to worried about killing the chip. :eek:

Lapped the IHS instead, didnt have the balls to remove it. Not got the cash to replace it if something did go wrong :D
 
Hi there,

Can someone tell me about stepping or give me a decent link that explains it. As far as I am aware it is a code on the CPU cover LBE0602 or something like that. Is it just a code that states what batch it is ie. what day of the week, die number etc??? Or does the code/stepping give more direct info like what multipliers it can use etc??? Just that I have been reading these forums for a while now and I still have not picked it up!!!!

Shame about only getting 2.7GHz on a 4800! I have managed 2.5GHz on my lowly AM2 3800x2 with stock cooler! Glad I did not splash out on a 4800. Do people manage much of an overclock out of the FX62??? Seems to me these higher chips are just the best couple of cpu dies from the wafer clocked to the limits.

PS... Just found the numbers I wrote down from the chip. I will just give the middle line (seems to be the one that people use)
LDB4F 0626XPdw ...... So what stepping is this then????

Not sure thats the right part of the code. Mine, for example is a CCBWE. No idea if that is good or not, or what it really means. It doesnt change anything about the CPU, just as you say contains info about what batch it is. So if theres a good batch, others can check to see if they have one from the same.

But as said above, mine only goes to 2.7 odd, at safe voltages. So it really is in the clocking, not the stepping. Try it out, and see what speeds you manage :)
 
I am sure the code I quoted is the correct one. I guess its the difference is reflected by the fact that mine is a AM2 chip and yours is a 939 one.
 
Ok the full *** on my processor are ....
ADA3800IAA5CU
LDB4F 0626XPdw
xxxxxxxG60588

xxxxxxx=no. witheld for privacy

What I have found so far...
[1st codeline]
ADA = Athlon XP
3800 obvious
I=Package type guess I=AM2
A=Maximum voltage=A=variable
A=Max temp=a=variable
CU=Part definition=Stepping ??(dunno), dual core, 0.09 micron, socket AM2-----guess

So the first line is straightforward bar the CU bit ... other Part definition codes have been defined as having E4 stepping etc what this means????

[2nd codeline]
LDB4F =Cryptic to me sure the digits mean something ... this is the "stepping" people seem to refer to. Indicator of some kind of batch number I guess
0626=manufactured year 06 week 26 easy
XPdw=Cryptic to me sure the digits mean something ...

All I can glean from the 2nd line is date of manufacture.

[3rd codeline]
xxxxxxx=probably a wafer id number
G6=Some sort of sort code binning number
0588=last 4 digits I assume is the cpu number on that particular wafer (how many cpus on a single wafer these days???? I dunno is 1000ish a reasonable no??)

There we have it what I understand so far what the numbers mean. Feel free to chip in lol.... maybe this should be a new thread?

PS I have moved the stepping stuff to a new thread in the CPU section called "What the Hell is stepping?" as I should not have hijacked this thread!!!! sorry!

c61..... back to you!!! ... erm I would not use the AI controls or programs personally I would do the overclock manually following the oc guide at the top of the board. I would also make sure that you turn off things like cool'n'quiet and q fan control in the bios as they tended to interfere with my overclocking limit.

Let us know how you get on.

Very similar to my 4600 (yes, I know the OP was talking about 4800s, but the core is the same): takes 1.55v to get 2760 stable, but even 1.75v won't get 2800MHz running.

Decided to just stick with stock everything for the time being. Feels just as fast as it did when I had it overclocked. Havnt got the time nor patience to keep messing around now ;)

Got the CPU to 2.7 stable at 1.55v 225HTT and the memory 1:1 2,2,2,5 @ 3.3v but it would fall over at random times. Sometimes after an hour of priming perfectly.

Shame, because OC'ing is still pretty fun to me, but I just cant be arsed trying to find the sweet spot.

Good luck to the rest of you with 4800's :)

ppl are running the cpu`s too hot.
My +4800 would not do 2.8 Ghz at 1.6V untill i pointed the airconditioner at the cpu fan! rockstable but then the aircon packed up & system restest at anything above 2.724 on air..overheating cpu.
when i finally get the water sorted then i hope to pass 2.8
