PC3200 or PC4000/4400

post #1 of 6
Thread Starter 
Hey everyone this is my first post here at overclock.net, Im very new to overclocking, I have an AMD Opteron 146 (skt 939) which is stock at 2.0ghz with a 10x multiplier. I have an Asus A8N-SLI motherboard, and a Thermaltake Big Typhoon cpu cooler with very good airflow in my case. I have some generic PC3200 DDR400 sticks (4 x 512) Running at 2.5cl in dual channel mode right now, and have been able to up my FSB to 240 (while not changing anything else like voltage or memory speeds) and its running stable but wont go any higher... I would like to get atleast a 260FSB or even 280FSB if possible, and I think I need new memory to do it. So my question is what speed memory should I buy? All i want to do is up the FSB and thats it... if i have to change voltage thats fine but i dont want to change the htt or memory speed or anything like that, just want the FSB to be 260 or 280 so my processor will run at 2.6ghz or 2.8ghz. I am so lost as to which memory to buy to do this. Any help would be greatly appreciated. Thanks guys!

You just need to set the memclock option in the DRAM settings lower which will reduce the memory speed.
Eg. it's currently set at 400 which is in a 1:1 ratio with your HTT.
If you set this to 333, your memory speed will be 333/400*HTT.
So at 260Mhz, your ram will now run at 216Mhz. This will give you more headroom to overclock your CPU and won't cost you anything.

You'll also need to set the HT Multiplier to 4x upto 250Mhz and then to 3x beyond this to keep the system stable.

nice computer!! and welcome to overclock.net
yes i reccomend running a divider,
take me for example i was maxing out around 3.6 because of my ram
but then i was around 3.8 with a divider on a crappy mobo (according to most ppl on this website) so if rams the problem, run a divider good luck

do you need steps? or you know how? just askin(not in a degrading way towards your knowledge or n e thing) but i didnt know how to run a divider untill a maybe 2 weeks ago

No, I have no idea how to run a divider, ideally however I want to keep my memory at DDR400 but I want it to keep up with the FSB of either 260 or 280... I read when you change your FSB your memory is changed along with it... however I dont want to lower my memory to 333 in order to get a higher fsb that seems to be defeating the purpose to me... I saw this on newegg and it seems like the right choice http://www.newegg.com/Product/Produc...82E16820231021 but I'm not exactly sure... again I didnt have to change anything besides the FSB to get my computer from 2ghz to 2.4ghz but anything higher and it wont post... Is it 100% necessary to lower the htt if going any higher than 2.4? What are the steps people who have either an Opteron 146 or Athlon 64 3200 to get their speeds from 2.0ghz to atleast 2.6ghz or higher? IE what voltages are you having to change to, memory timings, htt and so forth. Thanks again for everyones help!

I'd suggest having another read of my first post
Setting the memclock to 333 (divider) will only set your memory to DDR333 if you leave your HT (FSB) at 200Mhz. The formula is there as to how to work out your new memory speed when using a divider other than 400, which is a 1:1 ratio.

Here is an overclocking guide for an AMD that should get you started:
http://www.overclock.net/overclock.p...king-guide.htm

Running your HTT over 1000Mhz (HT*HT Multiplier) will usually give you no extra performance and will only cause instability. Best just to keep it below 1000Mhz (set HT Multi to 4x from 200Mhz - 250Mhz; 3x after this )

Good luck
