Low mem bandwith P4B533-E

slkcrab · Aug 15, 2002

Was wondering if anyone had any input regarding memory tuning.
System specs: P4B533-E (1007bios) 1.6a runnin at 154FSB (2.464) 1 512 chip of Corsair XMS3000C2.

PCI/AGP is locked at 66/33 (70/35 didn't make a difference) DIP trick for the memory and set at 1:1. This helped improve Sandra, but I would like to think I should be at or close to 3000. Mem timing is 2-2-2-5. Any ideas???

Check out this post on the 3:4 hack.A guy named Mikki has this board and there is some discussion on the memory bandwidth for the P4B533-E.http://forums.anandtech.com/messageview.cfm?catid=28&threadid=828762&highlight_key=y&keyword1=3%2F4

SUCCESS!!!!!!!!!!

Yahoo!!! Success!!!

Lastride, thanks for your link. I had been following a similiar one at asusboards and where I screwed up was thinking dip1 was dip6 (turns out I was the dip) set the right one and using the timing of 2-3-3-6 (lowest I could go) got the following bench!

fitch21: simply turn your 6th dip switch on, it will activate 3:4 mem ratio above 133fsb

Does the 6th dip switch trick only work in jumper mode? I just tried it and I had no joy but am running in jumperfree mode - is that the problem? Does this mean I am going to be limited in my choice of FSB if I use the 3:4 divider as there are only certain frequencies listed on the jumpers.....

Just found out that the BIOS lies and 1:1 is actually 3:4, whilst 4:3 actually gives 1:1

Cool!
