Also, i've heard with the lanparty it's best to manually sest your RAM settings and not leave them to automatic.

Yeah but I use CPUz and it shows that they are at the timings they are supposed to be

use a 1:2 divider and one stick of ram and see what happens



One stick of Ram? may I ask why?


i guess you may.


A64s have onboard memory controllers that are normally the first thing to crap out. So lets see what happens with one stick.

ignore that and loosen the timings

Ok I tried the 1:2 ratio - no luck
1:2 ratio with 1 stick of RAM, system no boot
I just tried the alternate RAM slots- im gonna fiddle with that for a few minutes, loosen times and such, if that doesn't work I'll move em back to the old spot and work on loosening timings

i have no idea why it didn't boot- it just was beeping and there was no monitor activity... Obviously timings is not the problem, I put it at 3-5-5-9 at 225X10 and core 1 still failed, I'll try using a diff stick with 1X and then I'll try loostening the timings in the other slots

Ok just did 1 stick with 1:2 ratio and loos timings, again core 1 fails me. Let me just get this straight, the prime test I am supposed to be doing is Small Ftt's right? I'll try both sticks in the different slots with low timings now

Ok this is really interesting. When I run small Ftt's in prime, core 0 handles it fine while core 1 fails- it doesnt matter if I do them both at once or each one seperate, core 1 always fails. Now when I do Blend test, It can only run one core at a time but if I leave it to core 1 and do the blend test, I look in the task manager and see that core 1 is at 100% usage and it does not fail... what does that tell me?

Ok should I just leave Htt to auto or manually put it at 3? Also I read this about prime:

The other two errors messages, SUMINP! = SUMOUT and ROUND OFF > 0.40 are caused by one of two things:


For reasons too complicated to go into here, the program's error checking is not perfect. Some errors can be missed and some correct results flagged as an error. If you get the message "Disregard last error..." upon continuing from the last save file, then you may have found the rare case where a good result was flagged as an error.
A true hardware error.

could it be prime- should I test the cpu with another program

lol you got me stumped. If it was me I would reinstall one instance of prime and run it on core 1 to see what happens.

set it to 3 manually

change the instance that you were running for core 0 to core 1 and test. Dont worry about reinstalling.
