ok got my new system up and running and started overclocking

my 7900GTO is now a 7900GTX as i have overclocked that to 800mhz from its default 660mhz and running very stable

ive started on my AMD 4600+ x2 which started a 2.4ghz per core and im now at 2.7GHZ

however i can not currently go any higher, my temperature at idle is still around 19 - 21 and its not topped 26 at load yet so its pretty healthy on the temp side of things

any way i now need to downlockc my memory so that i can continue my overclock, i could not ifnd the settings in my BIOS, is their any other way to do this other than in bios?

Nope BIOS is really the only way to unlock your memory, and loosten the timings. Also what are your northbridge temps? I know that was a factor in my un-ability to hit the 4Ghz mark. You could also try changing your multiplyer.

cheers cam,
yeh i did think of changeing my multiplyer. my goal is the 3ghz (per core) mark and then im happy kinda..(ned more ram)

so bios is the only way to loosen my timeings.
cheers dude

With a 12x multiplier you need to hit 250mhz FSB to get the cores running at 3Ghz.

If the memory's holding you back, do the following:

1) Set the HTT link speed to 4x (from 5x).
2) Put the memory on a 333 (sometimes called 166) divider.
3) Set the FSB to 250mhz.

Should be fine.

(333/400)*250 = 208.125mhz (This is the frequency your memory will run at - should be OK as it's only 8mhz above stock speed.)

gettting an x2 to 3gig is not going to be easy

the memory controller on a dual core is not as stable as a single core CPU


good luck

2.7ghz for an X2 is a good max o/c. Don't be surprised if you don't get much further regardless of your memory settings.

You need to change the memory divider, which is a setting in bios which is used to manually select a lower ram type.

GeForce explains this above in step 2.

Step 1 is required because the hypertransport frequency will crash the PC if it exceeds 1000mhz

26degrees at load?!!?!?!? Damn I wish my card would do that.

Now all you have to do is flash it to a Geforce GO 7950GTX.

I think that was the cpu temp Bindoe.

Either way, it's not correct, niether CPU or GPU runs at those low temps without some very sophisticated cooling solution.

I've heard of 26C at idle with a tornado in the case and a zalman on the CPU but load? would have to be about 35-40C minimum I'd think....

actualy i just have the stock cooler and every temp monitor i have is saying 26 at load so that just rocks

i do however have a very very good case, i have the heatsink on the GPU then their is a fan right on top of it extracting it straight out my case their is also a 80mm fan on the back of it and a 40mm on the front. so when it comes to cooling its pretty well coverd, i am however looking at getting a water coolign system to keep the temps down in the summer

john

You must live on a glacier for temps like that.

Aren't you suspicious something is wrong when every other CPU in the world is double that in temp at load?

What is your room temp?

I once had a broken sensor that reported sub-zero temperatures.
