AMD 3500 Winchester reaching FSB ceiling too soon

Just put together my first machine. MSI NF4 SLI Platinum board with AMD 3500 winchester. I don't know exactly what I am missing, but anandtech says that you can get FSB speeds of 235 with fairly stock settings. I can't get past 220. I am probably missing an important BIOS setting, anyone have similar problems with the 3500 or MSI board?


Thanks,

Jake
 
As always we need more details:

FSB
Vcore
Vdimm
CPU Multiplier
HTT Multiplier
Case Temp
CPU Temp
Memory Divider?
Memtest Results
Memory Rated Speeds and actual timings from bios or CPUz
and anymore details you can procure for us 🙂

BIOS Settings to check - Disable spread spectrum, Lock PCI bus to 33, Lock sata to 100mhz etc etc
 
OK did a little more reading and checking my stats but I still can't get my FSB above 220MHz. I read that with the 3500, this should be able to reach 235 without changing voltages and tweaking memory. I think I am probably missing some crucial BIOS setting.
 
Oh and I already checked out that guide, I have isolated the HTT and it wont go above 222MHz. This should def be higher.

Well, you didn't follow the steps. To find the highest FSB and CPU speed, you need to drop the memory speed down to 100 from 200.
 
you using SATA drives? SATA ports 1 and 2 are not PCI locked on that board

plug em in to 3 and 4 and you'll get nice overclocking

I did drop the memory, didnt know that was the divider. It wont get better than 222.

You don't need it to get better than 222 you need to set the divider so it is lower than 220.

You need to list exactly what your settings are so we can help.

HTT:
Voltage:
Mem divder:
ram timmings:
ram volts:
LDT:

LOL, now after looking up I noticed that thriemus was the first one to reply and ask you the same thing, details man we need details.😀










 
FSB - 222
HTT - 5X
Vcore 1.55V
mem divider i have been setting to 100, cause it should isolate the FSB
ram volts 2.6
CPU multi at 6x to isolate FSB again.

If i do successfully isolate the FSB, shouldnt that be my highest possible FSB overclock as well? After i begin to increase my multiplier and HTT ( if i knock it down to test), the max FSB overclock will be limited right?
 
Your HTT should be at 1000 or less at all times. The HTT (FSB) multiplier is LDT, which should be set to 4X. Also, you don't need 1.55 vCore at 222x6, that just causes unnessecery issues with heat.
 
Check for voltage fluctuations on 12v and 5v rails, very likey to be whats stopping you.

IMHO a $35 power supply is never a good choice, especially for an NF4 board they are really picky with power. The wattage rating means nothing, 600w yeah right!, just like those 1000 watt speakers you can buy at the flea market.

If you want to O/C I strongly suggest that you get a real power supply.
