Hello. I'm running an Epox EP-8RDA+ mobo and recently added PC3200 DDR400 memory to it. The person that initially built it had PC2700 in it to save money. Normally, I'd have bought 2 1024 sticks, but I was able to find a crazy deal on 512 sticks of Kingston Value RAM. I've got 3 512 sticks of that now (KVR400/512R).

When running the PC2700, I believe I remember it running at 200MHz. The PC3200 I just installed runs at the same frequency rather than the 400MHz I figured I'd be able to pull out of it.

My question is this: Is there anything I'm doing incorrectly that is impeding a faster memory frequency? Some of the topics I've read up on seem to indicate that this board has issues with memory. Would a BIOS update allow for better memory compatibilty? The BIOS update notes from Epox didn't do me much good.

Here's my BIOS info:

BIOS Type Award
Award BIOS Type Phoenix-Award BIOS v6.00PG
Award BIOS Message 03/05/2003 For nForce2-ST Chipset
System BIOS Date 03/05/03
Video BIOS Date 07/19/04

BIOS Manufacturer
Company Name Phoenix Technologies Ltd.
Product Information http://www.phoenix.com/en/products/default.htm
BIOS Upgrades http://www.esupport.com/biosagent/index.cfm?refererid=40

Any help is greatly appreciated. Thanks in advance.

200Mhz is the proper memory frequency for pc3200.
It is double pumped to make an effective frequency of 400Mhz.
If the pc2700 was running at 200Mhz then it was overclocked.

Thanks much. I probably should have came here before trying to set the frequency higher on my own in BIOS. At least I learned about the CMOS battery and how to reset the BIOS in the process. :rolleyes:

Again, thanks for the quick reply.

Edited for spelling

hey amano,

the pc3200 supports an FSB of 200mhz, therefore a total of 400mhz FSB total(200mhz x 2). at 400mhz FSB, the total bandwidth is 3.2gigs and thats why they named the memory pc3200.

now pc2700 supports an FSB of 166mhz, a total of 333mhz(166mhz x 2). at 333mhz, the total bandwidth is 2.7gigs.

if you are running 200mhz on that computer then the pc2700 memory is overclocked. but is the system stable? i know the epox 8RDA+ was one of the best nforce 2 motherboards back then. is a major overclocker too.
