Having trouble OCing my A64 3000

I raised the FSB to 220, it ran stable at 2.2 ghz, then i tried 230 FSB and it wouldn't post. Then i tried 255x9 with memory/fsb ratio at 5:6 with HT multiplierx3. Still wouldnt post. My mobo won't let me change the CPU voltage, so i couldnt try to up that. What can i try next?
 
Im an OC nub myself, but as far as I know, you have one of the best s754 mobos for overclocking. To change your CPU volatage, go to the Genie section of the bios, then turn off cool and quite. Try upping the CPU and memory voltage. I believe that the XMS' default voltage is > 2.7V. GL
 
Well, i know i CAN raise the vcore, but it's all greyed out now so i can't touch it, i tried turning off cool and quiet and i still couldnt raise it.

Should i have to be upping the vcore so soon anyways?
 
Yep, latest version.

Also, maybe i should mention my Vcore goes up and down a lot, minimally, but it keeps changing, same with my CPU speed. Is that normal? My Vcore likes to stay around 1.45, when it should be 1.5 all the time, it seems like.
 
If your vcore and CPU speeds are going up and down at the same time, then that's cool'n'quiet doing it's job. It drops the multiplier *and* the vcore when the system is not under load. So if the CPU is at 1GHz, then don't worry if your vcore is lower then 1.4.
 
are you sure you turned off cool and quiet? it really limits your oc. The vcore shouldnt be greyed out though. IS there some kind of jumper on the board? Read the manual.
 
350W Antec PS, i got a lot of stuff in the case. Was hoping i wouldnt have to buy a new one, might have to - is there anything else i can try?
 
Just a quick question in the bios for the voltage it doesn't say vcore it says cpu vid control for the voltage. Is this greyed out or not. I have the same board and it works fine changing the voltage.
 
Ok, now i'm running at 2340 mhz, HTT 260X9 with 1.65 vcore and 5:6 memory/fsb ratio, HTX3. Not quite sure how stable it is yet, was showing temps of up to 57C, which is quite a raise from my normal 39c idle and 48c under load temps. Should i keep climbing? These temps are getting a little scary, hopefully they won't raise any more. Cool and Quiet is disabled now too, so that may be part of the problem. I can turn Cool and Quiet back on when i'm done overclocking, correct?

Did the Sisoft Sandra CPU Arithmetic Benchmark, so i guess that means it's stable, or at least fairly stable. Should i try a different multiplier?...Different Mem/FSB ratio?
 
I would consider getting a better heatsink for that and you can rasie the vcore even more if needed. Underneath where you change the voltae there is an option which will take your vcore and then multiply it by say 104% to get a higher vcore.
 
Can temps really be that different though? From 39c idle to 58C under max load? That doesn't seem right.

Any advice? Could really use some help.
 
Are you using the bios to find the temperatures because the bios has much higher temps than sandra and my other temperature monitors. If you are serious about overclocking I still recomend using a new heatsink. I am using a Zalman right now and my temps never go above 35C
 
I might, but that's another $40 in the hole =/...probably, which model do you have? Plus this overclock wasn't going so well anyway, and probably won't be able to OC too high even if i do get a great heatsink.
 
Went ahead and bought it, probably won't help my overclocking much, but at least my temps won't be so crazy.

Still open to overclocking advice as i don't really know what i'm doing 😛, i have it back down to 2.2 ghz now, stock voltage and stuff. Will overclock more when i get my Zalman installed.

Are you reading your 35C from the motherboard? Or the monitor that came on the motherboard cd? Then can I ask which version of Bios you are using? I have 2800+ on this board (not overclocked yet), and motherboard and the monitor says my temp is 40C ~ 42C. But my temp probe that I put next to the cpu core ( and its flush touching the side of the core) says around 34C~35C. Is the temperature sensor or monitor on this board accurate?



 
I am using sisoft sandra and it seems pretty accurate. When I was using MBM5 I compared the two and they were the exact same. I can't use MBM5 now though because it doesn't support the Lanparty 🙁

And Jacktackle which one did you buy the all copper of copper and aluminum
 
Got the all copper one.

So would 1.7 Vcore be 100% safe? I got a nice heatsink and it should keep the temps down. Going to overclock more tonight, and i *can NOT* have any errors. Any OC advice from the pros out there? =p - Should i use a low multiplier?
