Thread: GA-EP45-DS3L - 4GB 800 MHz or 1066 MHz that works?




  1. #1

    Default GA-EP45-DS3L - 2x 2GB 800 MHz or 1066 MHz RAM that works?

    I saw another thread where Mushkin DDR2 800 MHz modules were recommended. I am upgrading a build that I did about 4 years ago (Pentium4, AGP, etc) and decided on the GA-EP45-DS3L motherboard so far. I will be using the Intel Core2 Duo E8500 for the processor. Will either of these modules be stable with the motherboard? I haven't decided on overclocking at this point, but the potential exists due to what I have read about the Core2s in general.

    Here are two I am looking at (non-eVCI):
    1. 2x 2GB DDR2 800: Newegg.com - mushkin 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory
    2. 2x 2GB DDR2 1066: Newegg.com - mushkin 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory - Desktop Memory


    Any other recommendations? I would like this install to be as painless as possible.

    Also, are there any potential issues adding in another pair of 2x 2GB down the road as far as stability goes? With todays prices, 8GB is tempting.

    Thanks :)

    Either of those would work great! I am using the 996580's now and they will do 1066 just with the same looser timings. So you may want to grab the 996580's and save some cash.

    8GB of them would work fine for sure.

    Ya, prices are dropping fast these days. I see those 996580's are $60 now with a 20 rebate. I bought my first set of them at $120, and second at $80. Now that you linked me and I see the price I may grab another!

    That's great to hear!

    I'll probably be getting my parts together within the next few days, though depending on timing, Thanksgiving might get in the way. As far as installation goes, do you recommend installing one module at a time and verifying POST before getting too far ahead? Should I be able to POST with the defaults? Also, I noticed that the Mushkin memory has higher voltage specs than it says for the motherboard (2.0-2.1 vs 1.8). Is that something that is just fixed in one of the BIOS settings?

    Finally, does BIOS chart that you post to get more info from people just use settings from the BIOS itself, or does that require a Windows tool? The reason I'm asking is I was planning on just putting Ubuntu on here, but have an XP CD around if necessary.

    Thanks again. I have so many more options now than I did with my Intel board 4 years ago

    Well, that all depends on how well you know a BIOS. 1 2GB stick for sure should work in Auto, 2x2GB may or may not. You will need to change several things for both. You will need to set your ram voltage to 2.0-2.1 (Yes it is a BIOS setting and easy to find and set) and you will need to set MCH Voltage to 1.2-1.3 (Maybe 1.24-1.28 would be fine) and trfc will need to be set to at least 52-62. Set performance enhance to standard for sure.

    The BIOS template I post you just print out, or write down your settings and come here and post them back in the template. No apps do it, so you will be fine whatever system you use. Just has to be done manually

    Ya, TONS of options in P45 BIOS for sure!

    Here is a template for you so once you get built you can post back what settings you are using, and what you want to try and I will advise back >>>

    Thanks for the info. I think I'm going with 8GB of the 800 MHz, so I'll be sure to post back with any issues or successes.

    Good luck with your build, and let us know how you get along!

    I wanted to let you know that my build went smoothly as far as memory goes. I put in 2 sticks (4 GB) and changed the BIOS settings to MCH Core of 1.200V and DRAM Voltage of 2.000V. I thought I set tRFC manually the first time, but now when I look it is set to an auto value that is within your suggested range. It is set to 52.

    With the stock CPU cooler, the CPU temperature in the BIOS monitoring section was about 56 C, so I decided to get an aftermarket one. I went with the Zalman CNPS9700 LED, which is massive to say the least. However, once it was installed, the temperature in the BIOS was something like 37 C on startup. I've attached an picture to give a sense of size. Don't mind the power cables - this was before I installed my hard drives and optical drives.

    Here is a breakdown of my new parts:

    • Motherboard - Gigabyte GA-EP45-DS3L
    • Processor - Intel Core 2 Duo E8500 3.16 GHz
    • Heatsink/Fan - Zalman CNPS9700 LED
    • Memory - 2x mushkin 4 GB DDR2 800 MHz kits (8 GB total)
    • Video - EVGA GeForce 8800 GTS 320 MB
    • Power - PC Power & Cooling Silencer PPCS500 500W
    • Case - Antec P182


    I got the video card for a great price from a friend who purchased it for SLI, but never installed it. I picked up the P182 because my Sonata didn't really have enough room for the video card and definitely not enough for the heatsink.

    I have an Audigy 2 ZS (PCI) that I was going to install, but it doesn't fit with the IDE connector is in use. I still need that for my two optical drives. I just set up onboard sound, which seems fine. Plus, you can easily hook up the front-panel audio connectors. The hard drives are a 300 GB and a 500 GB from my last PC that still have plenty of life left in them. I see the 1 TB drives are quite cheap now, but I think I'll hold off since I just bought all of these parts. One of these days ...

    Congrats on your build!! Ya, Those are huge! I used to use one in my case and liked it very much!

    Looks nice and clean in your case, good work!
