Upgrading from a 939 socket motherboard

My friend wants me to rebuild his computer. Currently he has a 939 socket Asus A8n32-sli deluxe motherboard, an AMD 4400+ CPU and pc 3200 ram. Everything else is worth keeping. He is not a gamer and mostly uses the computer for internet browsing, word, excel and AutoCad/ LDD. He is giving me a $200-$300 budget to purchase a mobo ram and cpu. It would be great if he could get a quad core but with the budget it doesn't seem plausible. If he were a gamer I would get an intel set up but he not so i'm not sure if a phenom set up might be worth it for the cheaper multi-cpu performance. Please help me with some suggestions.

It's probably a good idea to list all the other parts being used so people can be on the lookout for incompatibilities.

You could think about one of the new triple core CPUs: Phenom II X3 710 2.6GHz $119
And the quad core prices arent atrocious: Phenom 9650 2.3GHz $126

I built this system a couple of weeks ago. I used some G. Skill DDR2 PC26400 I already had. I like using this processor as much as my C2Q 9450. A night and day upgrade from socket 939.

AMD Phenom II X4 940 Deneb 3.0GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM2+ 125W Quad-Core Black Edition

^ It's a nice cpu, but the board is a bit dated. It doesn't allow for much future upgrades.

You are better off with DDR2 800 RAM than the 1066. It is more stable and the timings are better. The intel builds are better overall quality than the AMD builds right now.

Intels currently running. Q9450, Q6600, E8400, E6600. The PII 940 is better than the last three and almost equal to the Q9450. The ASUS 780G is as stable as it gets get for $80. Sure, if OP wants Intel, no problem, but for around $300 for CPU, MB and RAM it is almost as good as sex. 8)

It's not a bad board. But it will handicap any future upgrades. No options for a second card. The e7400 can be oc'd ~3.3Ghz rivaling the e8400/e8500 on stock.

PII 940 @ 3.6GHz is equal to Q9450 @ 3.0GHz. Close. The PII 940 is a hell of a processor for $229. OP would do well building with one.

I had the e7400 in my hand at Microcenter and put it back on the shelf. I'm glad I bought the PII 940 instead.

So the Gigadud P45 is a good board? I'll keep my 780G. :sol:

No question the PII is better, but also $110 more.

ragsters - It appears as if your friend is a mainstream user. With one exception, the software your friend is using does not require a lot of computing power. You mentioned your friend uses AutoCad/LDD. What does your friend do with AutoCad? Which operating system is your friend using? That is probably the main factor for making a recommendation.

It's about time. This should have been the first response. For what the OP is doing , his present rig should have no problems and he won't see any difference at all with the maybe the exception of CAD, exactly what do you use it for? That is the only thing I see that could show improvement by doing an upgrade.

I have three socket 939's in use every day. AMD 4800 X2, FX 55, AMD 4000+. I let a sixteen year old student have my fourth running AMD 3800 939 system for $50. PII 940/ASUS 780G/4GB PC2 as an eventual $340 replacement for one of my current systems worked great for me. If any of my three 939 MB''s or processors went down, I would not replace them even if I could. Discontinued years ago. Finding new 939 boards and CPUs is rare. I tried Sleezebay and got a dead A8N32-SLI. Sure replacing an old, discontinued system is a good idea. Was for me. I'm still in that process.

Thanks everyone for all the replies. He Is running Windows XP Pro but he wants to run Windows 7 when it comes out. His main concern was to have the ability to upgrade to a good amount of ram with a new board.

Welcome. I'm using 8Gigs with Vista 64 on my 780G. I had the PII 940 at 3.6GHz by simply raising the multi to 18x, but I am using an old socket 939 FX55 92mm HSF and it's not Prime stable with it. It is almost equal to my Q9450 at 3Ghz. There are a lot of great deals out there. 8)

My friend and I are both civil engineers with LDD being our main tool for designing. When building a surface there is a lot of computer power needed for it to run smoothly and for the computer not to crash. At least 4 GB of ram is needed but I'm not sure if Autcad is optimized for multiple cpu's.

I had a hunch engineers would be involved. We've got design engineers at the technology complex where I work. They definitely use the same software as you and your friend. I'll check with them and confirm; however, I am fairly positive they swear by quad core and lots of memory. I can't remember which operating system. I'll post again when I find out.

ragsters - It was such a beautiful day in Phoenix, Arizona. The sun was shining and it was pleasantly warm. The engineers left work early. I will have a response in the morning.

Thanks. I'll be hearing from you tomorrow.

I had the opportunity to speak with the design engineers this morning. They are using several different versions of Intel quad core cpu's, 16GB of memory, Windows Vista 64 bit operating system, and AutoCad 2008 which works well with a 64 bit operating system. There are different versions of AutoCad. The older versions do not work well in a 64 bit environment. The newer versions improve rendering and other features. They could not comment about AMD Phenom II simply because it is brand new and was not available when they did their upgrade last year.

There appears to another issue - video cards. The engineers felt priority should be assigned to the cpu and lots of memory at the expense of a video card. Their line of thinking was that intensive 3D video games are gpu intensive while the work they do is cpu and memory intensive.

Thanks JohnnyLucky that is exactly what I needed to hear. I'll try to get him to cough up more money and get a quad core with this Gigabyte board.

With a $300 budget going for quad core, I would do this:

Q8200 + GIGABYTE GA-EP45-UD3R + OCZ Reaper HPC Edition 4GB (2 x 2GB)

~$304 after rebates

can you give me the link for that?

The answer to your question is memory - The board with model #GA-EP45-UD3R can accept DDR2 1366 and/or 1066 memory. The board with model# GA-EP45-UD3P accepts DDR2 1366 memory.
February 26, 2009 10:25:33 PM

What is 1366? Don't they mean 1333?
February 26, 2009 10:27:16 PM

Are you also saying that the board GA-EP45-UD3P will not accept lower than 1366/1333. I thought that if it takes 1366/1333 it should take anything lower.

The board will take ddr2 1333 and allow it to be OC'd to 1366

It will take memory as low as ddr2 667

The difference is the option for xfire on the GA-EP45-UD3P

February 27, 2009 2:02:14 AM

OOPS! My mistake. I stopped when I saw the memory difference. Didn't see the CrossFire difference at the bottom of the charts.

aford10 correctly pointed out lower memory can be used. I wasn't thinking about that.

I think maybe I should shut down for this evening as my attention to detail isn't very good!

The boards are pretty much identical other than that.
February 27, 2009 2:17:11 AM

Thanks for everyone replies. I think I am going to go for the GA-EP45-UD3R version or the non crossfire version.
