Gigabyte DS3 o/c'ing problems - post HERE !!!

Hi folks, found this thread in my search for an answer to the problem I have with my DS3, but it appears that I am in the same boat. :(

You can add me to the list of the users unable to overclock their DS3 at all, well not from the bios anyway, can overclock using Easytune but would rather not use a software solution to do it since Easytune appears to have enough bugs itself.

Been through Gigabytes email support but got enough canned responses to open a can factory even when pointing out this thread.

CPU: Intel E6400
Motherboard: Gigabyte DS3 of course
Video: Palit 7900GT Sonic 512MB
Mem: OCZ PC2-5400, 2x512MB Sticks, Part No. OCZ26671024VPDC-K
Hard Drive: Maxtor 200GB SATA
Optical Drive: Pioneer 111D
Assorted USB peripherals.

Please Gigabyte, find a solution to this problem some time soon.

Anyone know why I cant do Cas 5 1:1 on my DS3 :confused:

If I set it at cas 5 bios it reads it sets it as Cas 3, which is why I cant get past 3.85Ghz (using Cas 4). If I could do Cas 5 I think 4Ghz easy as my mem is pretty stable @ 515Mhz doing Cas 5.

I cant change it in MemSet either as it just crashes.

I have manually set Cas Latency to 5 in bios. As you can see it actually sets it to Cas 3, which is preventing me doing 500+ fsb.

Currently using F4C bios.

I can do Cas 5 4:5 ok but not 1:1.

Thx

Here's a question to those that haven't been able to OC at all - which SATA ports are you using? The GSATA (controlled by the JMicron controller) or the orange ones (controlled by the ICH8 Intel southbridge)?

When I use the ICH8-controlled ports, I can successfully overclock in BIOS but lock up about 3 cycles (of the little blue thing) through in the XP loading screen (this began when I first tried to up my Vcore). When I use the GSATA (Jmicron) ports, I can't overclock at all.

Could someone else just try this out? When using the orange ports I can boot into safe mode, but as soon as my keyboard's numlock light comes on the XP loading screen just freezes. I don't really feel like reformatting but I would if that's what I need to do to fix the problem.

the CL3 display is a bug, it is not actually CL3

It still appears to me there's a bug with the cas latency on F4c. When I use the 4:5 ratio I can get my memory stable at ~460Mhz. However, when I leave all the settings exactly the same, but change the ratio to 1:1 the system won't even load windows. Can't think of anything else it could be really :confused:

yeap, it's not CL3, somehow programs get a bad read from bios settings :|


to you guys, there must be sth your MB doesn't like. in 99% cases it's gpu or ram... i dunno what else... i did even try to o/c my without drives, without anything in PCI and so on... and the problem was solved only by another vga card...

It is CL3, when using 4:5 I can do CL5 & my mem does over 515fsb.

When using CL5 1:1 it sets it as CL3 & they wont go past 470/480fsb!

It does NOT change the RAM timings! How many times do we have to go over this? I'm sorry, but this has been discussed to death. CPU-Z cannot read timings at all correctly on the DS3.
