what is limiting my OC

post #1 of 6
Thread Starter 
ok so first off dont worry about temps, because even with a cheap HSF, my 13 fan case mod creates a vacuum in my case allowing my HSF (which sucks in) to get high velocity air moving form higher pressure outside through the only hole where air can go in (the rest of the holes air is forced out by fans) and my temps are fine

ok i have (as you can see in my specs below)

AMD Athlon 64 3800+ Venice skt 939
DFI nf4-DAGF
1GB stick of pc3200 ULTRA RAM

i get BSOD's and program errors and weird OC-related troubles with windows when i OC past 2.58GHz

i tried voltages (ram and cpu) but i know (and they didnt) make a difference as its stock is 2.4 so 2.6 ghz is not much of a change

is it the ram?

what combos of multiXCPUvoltageXFSB (and RAMvoltage have worked the best with this particular CPU (or similar, like 3500+, 3400+ A64 venice core skt939)

(NOT 3700+, thats SD core)

Whats your...
LDT setting
RAM speed setting (ie what divider)
Memory Controler voltage
Chip set voltage

Also, can you and did you disable USB legacy support?

Whats your...
LDT setting -whats that?
RAM speed setting (ie what divider) -1:1 doesnt putting a divider decrease performance, especially in an A64 system. cause its not worth having a little extra CPU speed if the ram cant keep up i mean its actually almost slower cause of its inefficiency....
Memory Controler voltage-right how its stock 2.7 i think
Chip set voltage-idk northbridge or south? also where in BIOS is it and why would it matter? i thought only
CPU and RAM voltage mattered...


Also, can you and did you disable USB legacy support?
i dunno so probably not, i know i cant boot with a live usb like a flash drive, that have anything ot do with it?

LDT stands for Lightning Data Transfer. It is the other name to Hypertransport. What speed bus are you running and what Hypertransport multiplier are you running? It sounds like you just raised your Hypertransport bus (not the multi) and kept a 1:1 memory divider. If you put your bus speed to 215mhz to get to the 2.58ghz and kept your memory running at 1:1 with the bus, you are probably running your memory too fast, thus getting the BSODs. Just as when you OC your chip and it is not stable and reboots, the same thing can happen to your memory that is OCed beyond what it is capable of at that setting. Either try upping the voltage to the RAM (vdimm) or throw a divider in to get the memory speeds back down. Dividers are not bad to have provided that you have the right divider in. It can allow you to greatly OC the main bus without having to worry about the memory speeds.

"Memory Controler Voltage" ie: south bridge is not the RAMs voltage, it's the "controler" that manages the memory. Typically around 1.2-1.4v, upping it may improve the memory controlers stability.
North Bridge an persay South Bridge can attain some improvment in stability, the harder you work the system OCing the harder they work, thus the possible inmproment in stability with increases in voltage.
Note, I said possible, helps some and not others.
