Re: EP35C-DS3R won't boot with new DDR3 ram

At the main bios screen press CTRL + F1 at the same time.
This will give you full access to most of the bios options that are grayed out and not modifiable.

In the MIT screen you will also need to set:

PCI Express Frequency (Mhz) ------- [100] <-- 101 is OK
Performance Enhance --------------- [Standard] <-- for now
System Memory Multiplier (SPD) ---- [Manual] <-- AUTO won't let you make changes

Re: EP35C-DS3R won't boot with new DDR3 ram

Hello again.
I had to change the memory to 2x 2GB, GoodRAM, at the store. Works, but I have problems with OC. System won't boot if I try OCing a bit. I'll test this more.
Thanks for suggestions.
Regards.
Fodan.

If you are having problems with booting or overclocking, go to http://forums.tweaktown.com/gigabyte...tml#post312040, post #4 and save the P35 generic bios template.
Open this template in NotePad or any plain text editor.
Enter your bios settings in the template, save the settings as a TXT file and then post your completed bios settings.

Note: Ignore all settings in the generic bios file and fill in your settings and enter AUTO where appropriate.
For any settings that are not in your bios, enter N/A in the setting's field.
Include a link to your memory's full specifications from the manufacturer's website.
Include a CPU-z screenshot that includes all four panels similar to post #13 with non-overclocked settings.
Your will probably need to set (G)MCH OverVoltage Control = +0.2V or slightly lower.

Let us know if you have any questions.

Re: EP35C-DS3R won't boot with new DDR3 ram

Hello,

I have read this post and I have the same problem exactly.
I bought 2 dims of 4gb each 1333mhz Kingston hyper blue and when I'm installing them, the computer not boot.(I try only one-the same)
I know the specs of my mobo telling only 4gb of DDR3 but like the guy who posted this thread I have read on the internet
that people succeed to install 8gb DDR3 on this motherboard.
anyone here encounter this issue? maybe I need to change few settings in the bios?
(I update the bios to F4 and try load optimized default - no help)
Thanks

@asafvak

We don't know anything about the hardware in your system except for which memory kit you have.

Using the bios template, fill in and post the bios settings that you have tried.

You might need to use a different 2 x 4GB memory kit.

I can't help you until you also provide a detailed hardware list.

We need detailed information about ALL OF THE HARDWARE in your system.

We can best help you after you create a detailed hardware list in the System Specs
portion of your forum profile at the bottom of the profile page or in your forum signature.
Be sure to include brand names and model numbers.
When you are done editing or creating your hardware list, save the settings.

Re: EP35C-DS3R won't boot with new DDR3 ram

Hi all,

i'm new and have the same problem.

I currently run my system with 4x 1GB DDR2 800 and wanted to switch to 2x 4GB DDR3 1333 after i heard that 8GB work on my EP35C-DS3R Board.

I bought this DDR3 Ram from Kingston and tried it on my board. The system isn't booting up. After first fire up (2-3 sec) it restarts. Than it boots for more than 10 sec, but restarts anyway without the "Beep" you hear when System is OK. This cycle never stops.

I searched through more than 20 Forums and read about xxxx Posts about my board and the running 8GB Ram perfectly. But mine won't work for any reason. So i got deeper in the substance and i think my problem is caused by my CPU. It only has 266 FSB (max. 1066).

My question is: Can i run 1333 MHz Ram with a CPU that only supports 266 FSB (max. Multi 1066) when the board supports DDR3 1333?

If no, could i overclock my CPU to get enough bandwidth to get it running with DDR3 1333? (I know that overclocking my CPU up to 350 FSB is possible without problems).

What do you think? Could this solve the Problem with the DDR3 RAM?

Here are my CPU-Z Stats:


(these stats are with one DDR2 bar installed)


If you need more Info about my System, i will post it.

Re: EP35C-DS3R won't boot with new DDR3 ram

@Oz_el_Ruso
Your chances of using 2 x 4GB of modern DDR3 memory successfully are probably slim to none.
You can try using only one memory module initially where you set the memory speed lower than the 1333MHz rated speed.
MCH Core voltage that is too high or too low can cause boot loops.

As I recall, most P35 and P45 DDR3 memory setups required much higher Dram voltage, usually up to about 1.8 volts.

I think that the only way that you will have a stable system with 8GB of DDR3 memory is to use an older memory kit that originally came out around 2008 or earlier. Modern DDR3 is designed to be used with more modern memory controllers with 16GB or 32GB systems.

Except for the current lower price, higher speed DDR3 memory speeds will have no benefit with your P35 system in real world performance compared to high quality, cas4 800MHz memory or cas5 1066 DDR2 memory. Current cost for high quality 2 x 2GB DDR2 memory kits is about $75 per kit on my side of the pond. My HyperX 1066MHz cas5 memory is superb at 844MHz with 4-4-4-10 timings. My OCZ Repear 1066 cas5 DDR2 memory is stable at 876MHz with 4-4-4-10 timings. YMMV.

Re: EP35C-DS3R won't boot with new DDR3 ram

So that means that even when I find DDR3 Ram with 1.8v, i wouldn't really notice difference between DDR2 800 and DDR3 1066?

The thing that I don't understand is that there are many people that can run their EP35C-DS3R with DDR3. I don't think that they all found RAM with 1.8 voltage, because the Threads where they posted were from 2010 - 2012.

By now I found nothing but I hope to find some 1.8v DDR3. DDR3 8GB here in germany costs ~60 EUR and DDR2 is up to ~80 EUR for the same amount.

Thank you for your help. Hoped that I not have to send back the RAM

EDIT:
I looked at the compatibility list of Gigabyte for RAM and there is for example the KVR1333D3N8 from Kingston that works with 1.5v. How can it be if the board only supports 1.8 volt like you said?

Re: EP35C-DS3R won't boot with new DDR3 ram

In post #23 I said:

As I recall, most P35 and P45 DDR3 memory setups required much higher Dram voltage, usually up to about 1.8 volts.

Your current 1333MHz memory is rated at JEDEC standard 1.5V (1.425V ~ 1.575V) Power Supply. I would NOT run any DDR3 memory with more than 1.65 volts unless it is rated at higher voltages.

A web search using: p35 ddr2 vs ddr3 memory performance includes an interesting 2007 AnandTech article, AnandTech | Intel P35 Memory Performance: A Closer Look, where they describe their results with P35 and P965 systems.

Review the P35C threads that said that they were stable with 2 x 4GB of DDR3 memory and which specific memory kits worked and what their bios settings were. You can use the TweakTown Advanced Search feature where you type P35C EP35C in the Keyword(s): field and select the Search Titles Only option.

In many of these threads, they had to start with lower memory speeds and perform stability tests and gradually tweak and retest with somewhat faster memory speeds. Your best overall performance will be when your cpu speed is overclocked even if you need to run with somewhat lower memory speeds. See if you can get your system stable with 800 - 1066MHz speeds using only one memory module. You will probably need to set (G)MCH voltage to +0.20 or +0.25 volts. Do not go higher than +0.30 volts for this setting. If you have a very good cpu cooler you shouldn't have any heat related issues with a higher cpu overclock. Also check out the excellent http://forums.tweaktown.com/gigabyte...ing-guide.html

See if you can find several P35C or EP35C web reviews where DDR3 memory was used. Over the years AnandTech has posted many excellent P35 and P45 motherboard reviews that included o/c results and bios settings.

@Oz_el_Ruso

Have you tried contacting Kingston Technical Support to see if they have any suggestions or recommendations?

• Company Contacts | Kingston Europe/Germany
• Contact Information | Kingston USA

Maybe they will let you RMA your current memory for a different kit that might have better compatibility.

Re: EP35C-DS3R won't boot with new DDR3 ram

To make it clear. I sent back the Kingston HyperX.
Bought this ones "Team Group Elite Series DDR3-1333 CL9 - 8 GB Kit" and they work. They are also 1,5V and they work. It is not depending on the voltage.

For the audience:
I can confirm that this is 100% working DDR3-Ram for the Gigabyte GA-EP35-DS3R (rev. 2.1) with Bios Version F4 (06/08/2009). See also my SystemConfig at my previous Post in this Thread.

Re: EP35C-DS3R won't boot with new DDR3 ram

Glad to hear that you found a compatible memory kit.
I found the following information at Teamgroup - official website - Memory Function

• Intel G41 G43 G45 series or later chipset
• Intel P35 P43 P45 series or later chipset
• Intel Q43 Q45 series or later chipset
• Intel X38 X48 series or later chipset

Thanks for the update.
