    Default Suggestions for new PC based on GA-EP45-UD3R

    Don't have a lot of $$$ to spend on this project, but wanted to get the group's opinion of the following CPU - Motherboard - Memory combo.

    I'll be reusing my PC Case, IDE DVD Burner (ND-3550a), WD SATA Raptor 150g hard drive, XFX HD4770 Video Card (recently upgraded), Monitor-Keyboard-Mouse, and Corsair CMPSU-520HX 520W power supply (recently upgraded).


    So here goes....


    Motherboard:
    Gigabyte GA-EP45-UD3R ( http://www.newegg.com/Product/Prod [...] 6813128359 )

    CPU:
    Intel Q9550 ( http://www.newegg.com/Product/Prod [...] 6819115041 )

    Memory:
    Kingston KVR800D2N6K2/4G ( http://www.newegg.com/Product/Prod [...] 6820134641 )
    or
    Kingston KVR1066D2N7K2/2G ( http://www.newegg.com/Product/Prod [...] 6820134655 )

    Ok...so now you know my selections.

    With today's economic situation, I'd prefer to get my best "bang for the buck"...so although a i7 combo would be wonderful, its just a bit too far outside my price range at this time. Also, PCI ports are important as I still use a modem (for faxing), WiFi and TV Tuner / Video Capture Card.....which I don't want to have to re-purchase.

    I'm not a gamer...nor do I wish to overclock the system, but I do want a stable PC. Other than the typical programs (Word - Excel - Outlook - Firefox...etc), I regularly use Adobe Creative Suite 4 Web Premium (Photoshop & Dreamweaver & Flash mostly) and do of video & audio editing occasionally for my family. I use older versions of Adobe Encore & SoundBooth.

    My final thought of concern is that the FSB on the Q9550 is 1333MHz...however, the Kingston memory is only rated at a 800MHz (or 1066MHz). There seems to be several threads concerning memory related issues that I would love to avoid <g>. So will my memory choice become a bottle-neck or cause stability issues?

    So based on your knowledge (especially if you own or have worked with these hardware models), I'd like to submit for everyone to kindly give me your valuable input and opinions so I can make a final decision. Your opinions are greatly valued and appreciated.

    Thanks in advance!</g>

    You can get the ram at 1333Mhz....but you have to OC and I realize you do not want that!

    I was about to say the exact same thing profJim.

    I also have nothing against Kingston. I've used their value RAM in 40% of the PCs I've built for friends and family. However there seems to be some fundamental problems with the combination of Kingston RAM and the EP45-(T)-UD3(P/R) boards.

    The list profJim has provided is excellent! I'd give any of the modules on there a go, and be almost certain to get a good result.

    I can confirm from experience that Corsair XMS2-6400C5 (1.8v) and XMS2-8500 (2.1v) are both compatible with the UD3 boards. Also the first set of RAM on that list (the GSkill) is known to be compatible. A member of this forum (grishkafool) is currently running 8GB of that same stuff with a high (500 FSB + ) overclock, and has had no issues.

    Your RAM will not bottleneck you in any way. The 1333MHz quoted FSB is infact what is termed as "quad pumped" meaning simply that 4 pieces of information can be transmitted per clock cycle. Its true speed id 333MHz (333*4=1333 approx). The motherboard has RAM multipliers which are selectable in the BIOS alowing you to run your RAM faster than the FSB.

    RAM speeds:

    On a 333 FSB with DDR800 (400MHz actual as it's "double pumped") then setting a 2.40 RAM multi will make the modules run at 400MHz, ie DDR800

    On a 333 FSB with DDR-1066 (533MHz actual) then a RAM multiplier of 3.20 would be used to make the modules run at 533MHz ie DDR-1066.

    Overclocking the FSB to increase CPU speed would simply alter the memory multiplier you'd want to use. For example if you were to set your Q9550 (333*8.5 = 2830MHz) to run over clocked at 3.4GHz, you'd simply raise the FSB to 400 (1600MHz quad pumped). at 400Mhz FSB, for DDR800 RAM you'd use a 2.00 (1:1) divider which would run the RAM at the same speed as the FSB. If using DDR-1066, you would use a 2.66 RAM multiplier to run the modules at 533MHz (DDR-1066).

    It can get a little confusing until you get experienced with the settings, and when you adjust multipliers in the BIOS it will show you the speed your RAM will run at using the selected multi.

    Your choice of CPU is great, as is your choice of motherboard. I know that you say you don't want to overclock, but don't completely write the idea off. If you're lucky enough to get an E0 stepping of the Q9550, they max out stable at around 4GHz - 4.2GHz in general. Even a modest overclock to 3.4GHz-3.6GHz will require minimal tweaking. If you really do want maximum bang for your buck, then you can turn your Q9550 into a stock QX9770 with the greatest of ease, and at 3.4GHz, you probably won't even have to increase CPU Vcore voltage at all.

    I have the same mobo and CPU and I had good luck with
    Newegg.com - G.SKILL 4GB &#40;2 x 2GB&#41; 240-Pin DDR2 SDRAM DDR2 1066 &#40;PC2 8500&#41; Dual Channel Kit Desktop Memory Model F2-8500CL5D-4GBPK - Desktop Memory

    And like Psycho says: this mobo/CPU combo overclocks very easily: it's not too hard to set up a couple of different bios profiles, so if you're doing something that requires more speed, you just load the other profile.

    WOW!

    Thanks everyone for your wonderful input!!

    CoolMaster...I had heard that Gskill was good, but looking over the forums here there seemed to be a few that had problems with it also. I'm sure they didn't ask for advise prior to their purchase...so thanks again!

    ProfJim...I'll take a look at the link you provided right after I complete this post. Thanks for getting that info for me. And yes, I agree with you and not wishing to start a flame war.....and want to purchase the best memory based on everyone's recommendations.

    I've seen several posts that mention GSkill and Crucial as good quaility memory. I was concerned that IF something was found wrong that it would be more difficult to diagnose and/or repair with a Gigabyte RMA.

    Psycho101...Thanks! I appreciate you clearing that up for me (memory question)....it was a concern about the bottle neck since I wasn't fully understanding the way it worked.

    As for the CPU....the Q9550 was recommended to me as a good "bang for the buck"....although I've recently read that Intel is about to release a new Q9505...but it doesn't seem to have the benefits of the Q9550. Thanks for your input on my processor choice.
    List of future Intel Core 2 microprocessors - Wikipedia, the free encyclopedia

    As for overclocking...I'll have to wait and see what stepping I receive from NewEgg. Is there a program or a location that will tell me which I have after I assemble the PC? Additionally, would your recommended overclock require a new heatsink / fan? If so, which do you recommend (I realize we might be getting off the subject...but just a bit is ok).

    Thanks Psycho101 all of the great info in your post.

    Climber...How long have you had your combo for? I presume your using the G.Skill RAM you provided in the link....any specific timings or other settings that you've found to be very stable? Thanks also for your input.

    One last question to the group. With the current rebate that Gigabyte is offering, would it be best to hold off on submitting it until the last possible date? Or is it even worth submitting? Several on NewEgg's site have noted issues with their rebate....and besides, $15 isnt' going to break the bank

    Thanks to everyone who has already posted (its 10:25pm currently) and will review the links and check back tomorrow. Have a GREAT evening!

    When you assemble the PC, run a copy of |CPU-Z. On the front page, there is a section near the top called Revision, which will show your processor stepping (there's a section labeled stepping, but it contains different info, not relevant to OCing). If it's E0 you've likely got a good overclocker. Even the C1 will do at least 3-3.2GHz on stock voltages.

    Not sure about the rebate thing, nobody offers them in the UK, so I don't know how they work as regards to when to send them off.
