Which one would be better suited for overclocking? I currently have the EP45-DS3L with a Q9550 clocked at 4.0 ghz (471x8.5). I was offered to trade it for a EP35C-DS3R, which triggered the dilemma.

I know that EP35c supports ddr3 which is the only reason I'm considering the trade, other than that I don't know if it's any good in terms of overclocking so therefore I need some advice. Q9550 at 4.0 ghz + 4gb ram or (possibly lower than) 4.0 ghz + 8gb ram, which one would you pick?

i'd take the ep35c just for the fact you can use DDR3... ddr2 is long dead. also wouldn't worry too much about oc potential, if you can even get a mild oc you should be happy. the difference isn't that much, and that chip has been overpowered for some time now.

Far as I remember the P35 can only take 8GB RAM, the P45 can take 16GB DDR2 (only 8GB DDR3), but finding enough high capacity DIMMs to do that may prove expensive and diffecult.

If its a free trade I'd do it since you can use regular cheap DDR3 to get 8GB RAM. Don't know about OC potential, that properly depends on luck of the draw...

I'd recommend against reverting from a P45 to P35 chipset. Spending money on either board for additional memory would also seem less efficient than simply upgrading to a more up-to-date Haswell or Ivy Bridge system.

If I were to switch to P35 I could easily sell my 4gb 1066 ram and buy 8gb ddr3 for the same price. In the end it basically comes down to the chipset.

My Q9550 E0 hasn't broken a sweat yet despite the 30% overclock and I've seen a big improvement in terms of rendering times in C4D so I'm planning on keeping it that way. My only concerne is if the P35 could handle the vcore voltage of 1.4500v.

good luck trying to break even.
it's old, and not many people are going to want it.

i've been trying to offload my core 2 duo machines for months.

Yeah, who's going to buy 4GB ddr2 for $80?

First question would be, are you actually memory limited? If so you could also get some more ram secondhand.

To me this only makes sense if you plan on upgrading the rest of your system in the near future so you could carry over the ddr3.

If you can hold out a bit longer, the days of ddr4 are approaching so you might as well skip ddr3 altogether.

Also, P35 is pci-e 1.0.

ep45 ud3r or ud3p is imo one of the best motherboards for this q9550. I am also running a similar setup aswell.. I wouldnt trade though..

I have the ep35c-ds3r. I just completed an upgrade. I tossed out the e7450 dual core for the x9770 quad core. Picked it up used for $300 on ebay. That's pretty much the max chip for LGA 775 I'm clocking to 4ghz and despite what the specs say, I'm running 8gb DDR3 corsair 1600Mhz ($80 at BestBuy). It's fast!! It's benchmarking higher than gen 2 I7's with a mild STABLE overclock! My graphic card is 7yrs old. A Geforce 9600 GT with 512mb. !'ve got $1800 in this system since I bought it in 2007!! :D:D Hoping to get 5-7 more years out of it, but looking for a new graphics card!

I say this in the nicest way, but you're crazy to spend $300 on a 775 CPU, when you can get an i7 Haswell for similar money. The only way that would make sense is if you had some expensive $1000+ software package that was activation-locked to that motherboard, and therefore you couldn't upgrade that board without incurring significant expense.

Thanks for the tip about the EP35C and 4GB DDR3 DIMMs. I had thought that the P35 chipset was limited to 2GB DIMMs, regardless of DDR2 or DDR3. (I have that board in a server.)

+1 You said it. DDR3, DDR2 -- that's still six to eight-year-old technology.

I have three LGA_775 C2D/Q systems fitted with 4x2GB or two kits each. I'm reticent about retiring the systems, because everyone is still happy with them. But I'm also shy about recycling six 2x2GB kits of what were once great G.SKILL RAMs for those boards. I don't ever remember having the feeling that I "squandered" money. I must have added a kit every couple years -- maybe for $60 or $70 a pop.

Pity . . . Even so -- you can get 2x4GB kits of G.SKILL 8GBPQ, but it's got a price-tag of $200+ dollars. I guess it could be nice if you could socket 2x4 or 2x8GB of DDR3, even if only 1333.

I wouldn't put any more money into an LGA-775 system, unless you can transfer the parts to an 1155 or 1150 system and get full performance you might ordinarily purchase for such systems.
