ASUS A8N-E Questions - Page 5

post #41 of 65
The difference between Skt. 939 and 754 is that 939 has dual-channel memory support i.e., when u put 2 identical memory modules in alternative slots, it'll work in dual-channel mode effectively doubling the bandwith available. But 754 has only single-channel memory and so there is no need for identical memory. But if u wanna upgrade in the future, getting 2*256 or 2*512 would be better.

What I would suggest is, keep the RAM that u've now as a stand-by and get 2*512 400 MHz RAM as ur RAM only runs at 266 MHz which is a ,ajor bandwith loss when compared to the 400 MHz RAM.

Run SuperPI Mod 1.4 32M test after every FSB increase - This after u find the limit of the RAM by using Memtest after the initial FSB increase. Initially u'll be increasing only in 5 MHz instalments and later in 10 or 15 MHz instalments. Use SuperPI when u go into the 10~15 Mhz phase. If not, download OCCT and run it for 2 hrs for every accumulated 30 MHz increase ( 3*10 Mhz at a time or 2*15 at a time ). That will tell u if the system is really stable or not.

And yes, ur RAM does increase in the same proportion as ur FSB if the RAM frequency is set to 400 MHz in the BIOS ( 1:1 ).

There's nothing worse that could happen. Ur system may not boot into Windows, random crashes or blue screens are what may indicate a bad OC.
cool. thanks alot freaky... how long on average does it take to complete super PI 32m test? Won't it take a while to get the OC stable if i run the OCCT everytime i increase FSB 30mhz? Is it worth it?

Also, is using JUST OCCT good enough to 'prove' stability or is it better to run memtest and prime 95?

BTW, could i set the FSB straight up to 227 (which makes 2.4) or is that not possible.. would it not be stable.

thanks reps to you

anyways i get to the pointy...

Q1: For my new rig (S939) i ahev chosen the ASUS A8N-E hobo, i was just wondering on the overclockabilitea with this surfboard. E.g. Easy navigation of BIOS, alot of settings (you guys all know what i mean).

I am pairing the hobo with a 3700000+ SD and some Corsair XMS3200 1gb kit (2.0-2-3-6, i think... correct me if i'm wrong )you're wrong

Q2: I have figured i can get 2.48897 easy, 218 * 11 = 2398Mhz, or lower with alot of effort (i hope). Do you guys know what pimps i can expect from the stock freiza @ those speeds? i dont think i have to use a divider (entirely sure). Do you know what speeds i can get the sheep to run at 240kph?, what timings?

Thanks alot guys for your output, greatly unappreciated! Reps to go around for useful answers for both of my questions and if they are in detail.

yes yes i know that about dual channel, but i hear somewhere that when you have 512 in piece, it disharge and charge memory faster than 2 x 256, coz when its 2 x 256, firs it discharge 1st module, and if it dont have enough room, then he goes to discharge the second...

but smart thinking anyway, ill have to sell that old memory to raise money for the new one then i get one 512, and when i upgrade my system ill buy another one.

Id say run 32M pi if it can handle it its stable enough.

The SuperPI 32M would take abt 45~50 minutes to complete. U need to run OCCT only for 2 hrs as compared to abt 6 hrs of Prime95. There is a post here which is on Revision E OCs. It states there that a screenshot of 2hrs of OCCT or 6hrs of Prime for would prove the validity of the OC.

Run OCCT on reaching 250 FSB. Till then run SuperPI 32M. This after u find ur RAM's limit. Increase by 10 MHz in the beginning to find out ur RAMs limit. Even after that increase by only 10 at a time.

And as I posted earlier, ASUS boards do not like FSB jumps. So, be patient and get a stable OC. OC'ing is never a simple process. It is always time-consuming and a frustrating process. But once u get the settings right, u can enjoy the time-spent.

thank you. thank you. thank you. Now i can get started on the OCing now that i realise the programs used to dertermine stability...

So, instead of Prime95 i can use OCCT, correct?
Also i will use memtest.
and Super PI 32M

Is that all?

what about for gaming, if it (the OC) passes OCCT then can i assume it will play games without crashing/BSODing?

Also i am gonna use an XP120 with AS5, so i should be set...

thanks again.

reps to you.

If it passes OCCT, then it will not crash while gaming provided that u do not have any video card issues. And since u've written that ur gonna use AS5, ensure that u follow the steps in the ArcticSilver website to apply it.
