ram speed probs with A7N8X-X mobo
Hi I bought an ASUS A7N8X-X mobo last year and was using an Athlon 1700 XP+ CPU. Then I bought some PC 2700 ram, which i was running at PC 2100 speed. More recently, I bought an Athlon 2500 XP+ CPU, which boosted my FSB to 333, and the ram automatically adjusted to PC 2700 (333MHz). That was when the problems started. Games and intensive apps kept crashing with "Memory can't be read" General Protection Faults. After a while of having an unusable machine, I set the RAM down manually to 80% (266MHz). This worked for a while. Very recently the same errors as before have started turning up again. Just today I checked the receipt for the RAM, and found out it was PC2100, not PC2700 (ie: I was lied to by the shop I bought it from, and they are now out of business - some advice, never buy new hardware from a "friend"
I ran the MemTest86 program, and it produced lots of errors with the RAM at 333MHz, but none at 266MHz.This is weird. I would now like to buy some PC3200 RAM, but am not sure if it will work properly at the 333 MHz speed of my FSB. If that is the case I will just buy PC2700 ram, and buy some PC3200 when I get a new motherboard - prolly 6 to 8 months away.
I appreciate any advice
