gigabyte 8iexp ram tweaking

Recommended by Wim's BIOS...

i have a gigabyte 8iexp motherboard and 400Mz corsair RAM, the problem is i cant run it at that speed

, so i was wondering if there is any way to change this, the bios settings only allow me to double the CPU host frequency, i currently have the ram at 182mz, i dont know much about decompiling bios's,. any help would be MUCH appreciated!

cheers - Brett

Hi Brett
If your RAM is at 182 MHz, does this mean your CPU is at 91 MHz ? Why not 100 or 133 ?

Not an over-clocking forum...

no, because my Pentium 4 is quad pumped, it has a 533 FSB, anyway the multiplier is locked at *19. im not exactly sure how it all works, the clock, is at 141Mz., and if u times that by 19 u get around 2.68GHz.

i know this forum is not about overclocking, this solely has to do with the BIOS settings, the end result is an overclock

sorry, i did actually make a mistake :oops:

, the ram is at 282 not 182 Mz

The ratio of memory speed to CPU speed is determined by the chipset; some allow 133MHz FSB for memory and 100MHz FSB for CPU. The only thing the BIOS may allow you to change is the RAM timing in the CMOS setup. If you have a BIOS that permits overclocking it probably allows you to change some RAM timing parameters as well. That's all I can suggest.

hmm, true, it dosnt allow me to change any memory timings in my cmos setup, so i guess ill just have to put up with it,
would anyone know anyone who would be willing to decompile my bios to fix it for me?

I have experienced problem with GA 8IEXP motherboard and RAM. Definitly there is big problems with E7205.It suports dual DDR 200MHz and 266MHz onlly (manufacturer words).It is logical that DDR 333MHz and DDR 400MHz will also work on 266MHz but there are the problems about it. I have unlocked my CPU and there are supported FSB from 100-166MHZ (CPU 400-664FSB).If You use DDR 200MHz You should set FSB to 100MHz and if You use DDR 266MHz it should be 133MHz.I tryed with 166MHz but memory still worked with 2x266MHz (it was DDR Kingstone 300MHz).Also I have problem with ATI Radeon 9500Pro and AGP 8x suport.System was very unstable and I must set up it to work as AGP 4x.Allso Intel anounced that E7205 has problem with AGP 8x and that won't be fixed!!! Ideal use of that motherboard is FSB 533MHz and RAM on 533MHz (2x266MHz) but motherboard with Intel 845PE chipsets are faster then this E7205 experiment.
