Help! My System crashes only a 227MHz HTT speed.

[anthrax]

My system crashes at only 227MHz HTT. Is there anything I can do to increase it ?

Its not my CPU as I have underclocked it with the low mulitplier.
Its not my RAM as I have underclocked it to less than 110 MHz too.
I have already tried cranking up the HHT voltage but it has no effect.


Mobo: Gigabyte GA-K8NSNXP-939
CPU: A64 3500+ clocked at 1600MHz
Kingston DDR 2700 clocked at 110MHz ( i am going to get new ram later.)

any time you boost HTT you are overclocking the ram and the CPU and if you dont have a working AGP/PCI lock both of those busses as well..
overclocking results are not guarnanteed..
there are a million things that can stop an overlclock.. ususally its ram or CPU or voltage.. you say you are underclocked.. but you are pumping the HTT which is overclocking ...

ctrl-f1 in bios and lower your HT multiplier to 3x, if that doesn't work, then that may just be the best your cpu/mobo can do

Thx Stardust

Cntrl F1 enabled the Advance Chipset Features Sceen.

I was wondering where the RAM Timing , HHT multiplier controls where...

Thanks

Okay, Dropped my HTT mulitplier and my board will do up to 245MHz. (which is pretty resonable.)

Now CPU overclocking questions..

The CPU seems to runs fine @ 2530 MHz (11 x 230MHz)......
It will post post and crash while loading windows @ 2585 MHz (11 x 235MHz) @ 1.7 Volts Vcore.


Is it risky running a Athlon 64 @ 1.7 Volts Vcore?

I am currently running stock cooling. Should i go get a Cooler Master Hyper 6 Heatsink and then see if i can push the system further?

I'd try a Thermalright heatsink or a Zalman 7000A-AlCu (or what ever the model number is). I wouldn't push more than 1.65V through an Athlon64 personally, stock is 1.45, and a .2V bump on an XP up to 1.85V was considered dangerous by many. The same bump on an A64 is a higher percentage than the same .2V bump on an XP.

1.7v should be just fine. I have had my old CO A64 3000+ at 1.76v for over 6 months and even up to 1.85v a few times. As long as you have good cooling, 1.7v is okay IMO.
