My cousin had called me yesterday to overclock his system consisting of the below stuff
AMD Athlon64 3200+ (2.0Ghz,1MB L2 Cache, ClawHammer core with SH7-C0 revision), with Stock Cooling
MSI K8N Neo Platinum, with a active HSF on chipset
1 SAMSUNG 80 GB SATA HDD (Plugged on SATA 3)
1 Samsung 40 GB IDE HDD
Iomega 16X DUAL LAyer DVD writer
3*256 MB RAM Made by NANYA Technologies (has been checked for compatibility on MSI Test Report)
Now coming on the problem
I checked the RAM for its Overclockability (honestly I had never heard of NANYA technologies), the RAM did good it clocked 280 Mhz DDR ie 560 Mhz with tight timings of 2.5-2-2-5 on 2.75V
I set the HT multiplier to 3 and started pushing FSB with CPU multilpier set at 9 and CPU core set at 1.6V and RAM set at 2.5-2-2-5 with 1:1 ratio
As I started clsoing towards 267 Mhz HT the RAM started showing errors in memtest86 I was damn shocked. I had checked the RAM to be stable at 280 Mhz DDR with the same timings.
I reduced FSB to 255 Mhz yet the same thing.
Finally just to see if RAM was the actual culprit I decreased the CPU multiplier to 7. BUT ALAS! the Ram showed no errors in memtest86 and Prime95. I was shell shocked.
Now you ppl tell me is the CPU the culprit for all this??? I think the memory controller of the CPU is damaged some how or is not working properly.
Anyways if the above stated conclusion is true what wud I say for the replacement of the CPU to the dealer??? I mean he won't understand the technical terms as Memory controller on dies, etc.???
Help me plz.
