Gigabyte-EP4-EXTREME with TWIN2X4096-8500C5DF problems


Titchy

Recommended Posts

Hi guys , i have just built my new system this week and its driving me mad , it worked alright for a day or two before i started doing much with it.

Now that i have installed a few games and stuff and started " using " the computer it is constantly rebooting and crashing . With the whole 4gb installed it actually stopped booting at all and i kept blue screening. A search in google with some of the numbers suggested it was faulty memory so i pulled the sticks out one at a time and found that one certainly seems to not want to work.

The other one worked fine for a few hours today but has just now started crashing as well , its really getting on my nerves !

Can anyone help me please with what my exact bios setup should be ?

I have an intel Q9650 CPU , fitted as well . The sticker on my ram says to set voltage at 2.1v so i have done that , my memory is 4gb -TWIN2X4096-8500C5DF and is version 1.1 if thats any help cheers .

I swear this pc will have rebooted about 25 times today :(:

 

Thanks in advance for any help ,

George.

Download Memtest86+ V2.01 from--->

Download CPU-z from
.

Shut the system down. Insert a single stick in Slot 1 (Closest to the CPU). Restart. Enter the BIOS. On the main BIOS screen press Ctrl + F1. You will see the screen flicker. Next select the MB Intelligent Tweaker option. On that screen you will see many additional settings that were not there before. Enter these values:

Shut down the System. Insert the other DRAM sticks. Restart and boot to the Memtest CD. If you pass Memtest, enter Windows and post screenshots of your CPU-z's CPU, Memory and SPD tabs. Show the SPD tabs for all four modules.

Hi thanks for the help , i will try that now , the only thing is , perhaps the description of my memory is misleading there, it is 4gb of ram total , on 2 x 2gb sticks which are meant to run at 1066 , i assume by your help there you were thinking it was 4 sticks and the speed they will run it will be 800? If it makes the system stable though i could live that to be honest :D:

 

I assume due to it just being two sticks i will just need to test slots 1 and 3 yeah ? Thanks very much for your help so far, i really appreciate it.

Sorry for more questions guys , but while i have built my own systems trouble free for years , i dont have a deep knowledge of bios settings so i just want to make sure i get it right !

 

In Advanced clock control you advise setting bios as follows :-

 

CPU Clock Drive: Auto

PCI Express Clock Drive: Auto

CPU Clock Skew (ps): Auto

MCH Clock Skew (ps: 100ps

 

I dont have an auto option in any of these 4 settings, just variables:-

 

CPU Clock Drive: 700,800,900,1000

PCI Express Clock Drive: 700,800,900,1000

CPU Clock Skew (ps): from 0 - 750 in increments of 50

MCH Clock Skew (ps: from 0 - 750 in increments of 50

 

Also in the timing settings you recommend 4-4-4-12 , the sticks say 5-5-5-15?

 

( Im not saying your wrong , i appreciate the help , im just not that confident doing these things so im just making sure we are not speaking about 2 different memory sets :biggrin: )

 

Thanks again.

 

Also my title has a misprint , that mobo is a gigabyte-EP45-extreme, i have it typed as EP4 not EP45 !

I just checked up on the memory , the description i gave for my memory stated 2x4096 but its only 4gb total i have so i checked the sticker , it says 2x2048 i actually copied and pasted the 2x4096 from my invoice for my pc but its a misprint as i only have and ordered 4gb total , its 2x2048 that the memory is just so its clear sorry for all the confusion guys!

 

They are CM2x2048-8500C5D .

 

Thanks again , sorry about that.

I had thought you were running with a four DRAM slot population. Please check the edited settings.

 

MCH Clock Skew (ps: from 0 - 750 in increments of 50

 

Set to 100

 

The timings were for 800Mhz (4-4-4-12). See the edited settings for 1066Mhz.
