Fixed Rebooting system crash?

[Overkiller]

Hi all,
system specs:
asus a7v133-C
1.2 ghz tbird 266
786mb pc-133
radeon 9700 pro
ibm 45 GB 75GXP

I am not 100% that my problem is fixed (lot more testing needs to be done) but w/ your help i do believe i've found out the problem w/ my system and why it was ina constant rebooting loop and then after reformat /reinstall it still periodically crashed...

I ran IBM's drive utiliity on my HD and it came up fine but we all know those HD utilities dont always catch bugs...Someone else suggested prime 95 in the distributed computing section....Basically this pushes cpu/mem/bus to the max and if something is wrong it becomes apparent w/in seconds...Here are my results:


9x133 = 1200mhz = Test Fail
8.5x133 = = Fail
8.0x133 = Fail
7.5 x 133= = fail
7.0 x 133 = Fail


~~~~~~~~~~~~~

9.0x 100 = 900 mhz = test PASS
10.0 x 100 = 1000 mhz = Test pass
11.0 x 100 = 1100 mhz = test pass
12.0 x 100 = 1200 mhz = test pass

hmmm

~~~~~~~~~~~~

8.0 x 113 = 900 mhz = test pass

hmm

~~~
7.5x 120 = 900 mhz = System CRASH
9x120 = 1080 = System Crash
Move to 9x133 again = system startup..test fail...system crash during reboot

9x130 = 1170mhz = test PASS.....

it look likes its the ram modules after all... Is it ok running them @ 130 mhz instead of 133...I ask this b/c when FSB is set to 100 mzh PCi bus is 33 mhz...will the pci/agp bus mhz damage my cards b/c i'm running the FSB @ 130 mhz instead of 133..??

Testing some more to see if it crashes..hopefully i have fixed my problem...I will keep you guys posted! for all those that helped thank you very very much! {sinfulweeper, confused,bgeh}

In the FS treads people have a lot of PC133 memory for sale. I would suggest buying a good stick. Corsair, Crucial, PNY, or at the very least Kingston, just be sure to avoid generic.
Or you could always go to a local store. But keep the above in mind.

What about your CAS settings? Try lowering them to 3-3-3 and see if it still fails memtest86. Not all PC133 memory will run @ fast CAS settings.

I have a setting in my BIOS to run "Turbo" or "Normal".
When using turbo system is not stable when running DC client and using computer.

2 dimms (which were in b4 the huge crash that started this) are pc-133 from CRUCIAL. <-- the higher quality stuff that many many ppl took to 140 and far beyond..thinking maybe 141 over a few days might've created slightly too much heat for them...

the other 256 MB dimm is no-name from someone else's pc..going to take out the 2 crucial dimms , running the 3rd @ 133mhz...put in 1 crucial...same thing, try the other one...it could just be 1 of them that is faulty (or both crucial dimms)...either way

its not worth my money to buy 2 new dimms now..if need be i'll run it @ 130mhz..its only 3 mhz off and my proc. is 1170 i think instead of 1200..not *that* big a deal...

i'm saving up for major AMD 64 overhaul.
Thankfully i already have a 48X burner, pioneer 16x dvd, radeon 9700 pro,and SBlive 5.1 along w/ speakers/monitor that i can salvage so the upgrade wont be *that* pricey..
