Only unexpected costs were a network card after a win 10 update caused the inbuilt gigabit to stop working (tried everything short of a rollback) and a new fan as the HP original sounded like a Hoover!

Very interesting stuff! Some time last year I tested putting a LGA771 x5355 into my GA p35 DS3R, swapped out my E8400, but I never tried using the DDR3 capability of the board while doing the testing. They worked out really similarly with the few video cards I had, in my limited testing scenarios, but ended up using twice the wattage, so I gave up. Long story short: Thanks! I always wondered if it was strictly frequency / timings dependent.

This really answered my questions :) I'm am late here lol, but I got one of those crazy high end ASUS boards with a Q9300 for $35NZD from a junk shop lol. It's running really well with windows 7 and a GTS250 :) I'm making a second system around a Q6600 but only have high end 775 boards left. It's good to see its not going to make much of a difference :)

Main culprit is the memory controller itself and the additional latency since the memory controller is in the chipset. Anandtech also tested this back in the day and there is A LOT of performance to be gained is you tune the performance level. I had a 8GB DDR2 OCZ memory kit that was rated for 1150MHz CAS5 combined with a P45 chipset (DFI Lanparty motherboard) and a 333FSB strap (running 492FSB with a Q9650 @ 4.43GHz watercooled) with a very low performance level (read: very aggressive timings between the memory and the memory controller). It was about 1,5x faster than a motherboard running auto settings and some cheap DDR2 800 memory...

But as you said, difference in performance is close to zero, DDR2 800 MHz vs DDR3 1333 MHz is the same, sometimes it's even better in some tests for DDR3. Socket 775 boards were not ready for DDR3 yet, DDR3 started to make since with 1600+ MHz with later sockets. Combination of socket 775 and DDR3 brings you just problems.

FSB is heavy bottleneck and you really can't increase it that much. To match just bandwidth of 1066MHz dualchannel memory, FSB needs to hit 533. Only handful of boards could do that.

A DDR memory channel is also 64bit but since there's two of them, it can transfer 16bytes. 667 x 16 = 10672MB/s.

Good video as always! The two uses for DDR3 on LGA775 platform are: 1. High BCLK OC 2. 16GB of RAM achievable The first one is quite obvious,as going over 500BCLK(or even higher) is really hard with DDR2,high frequency DDR2 modules are way too expensive and too demanding for cheap motherboards. Even DDR2 1200MHz cost an arm and a leg back in the day,not to mention their scarcty in 2018. With DDR3,1200MHz isn't a big problem as 1333MHz modules are everywhere. One of the highest BCLK record was done on Rampage Extreme with 710MHz BCLK(at 2:3 ratio means 2133MHz DRAM frequency). And the best BCLK record is also done on DDR3 board,it's the EP45T-Extreme with 750MHz BCLK. The latter is doable on DDR2 but requires very expensive and ridiculously rare DDR2 4GB DIMMs(and very picky with motherboards),with DDR3 it's easier with double side 4GB modules. Other than those two,using DDR3 will give you a little bit more headaches as DDR2 is cheaper and easier to find(the compatible ones). Also,if you want to fine tune the absolute best performance,timing is everything and high end DDR2 modules will get you covered.

1: Highest BCLk was not on the legendary rampage extreme but on a gigabyte ep45T-Extreme, 750Mhz... 2: The problem with DDR2 high freq is a: the good stuff only comes on 1GB modules and b: the MC doesn't like high clocks with 4 modules so in practice you're limited to 2GB at 600+ FSB :)

@@KitKatFresse - You are right about EP45T-Extreme but that MB had so loose internal timings on the NB that a DFI P45T2RS Plus at FSB 400 could easily beat with the same memory on SuperPi or Wprime the EP45T-Extreme at 420mhz just tightening the latencies on the DFI. I have a friend who had that MB and I was beating the crap out of him on SuperPi and WPrime with the same CPUs and OS. The second one was I thing the Biostar IP45 which could reach crazy FSB speeds. The best kits with DDR2 were the one with Micron D9GMH IC's. I've had two kits on my hands back in the day. One was the A-Data Vitesta Extreme 800mhz (the red ones) and the second one was the Team Group Xtreem 2x1GB PC9600 (tall radiators). The second one wast one of the best kits on air I've seen. I could reach on cold air (-5 ambient) and a Delta blowing on them 1333mhz 5-5-5-5 @2.45v or 1200mhz 4-4-4-8@2.45mhz, all of those on the DFI LP P45T2RS Plus and an E8400 C0. From what I've heard that kit could do 1500mhz with looser timings and sub zero, and that was DDR2... I really loved that MB, to fully understand the BIOS you needed to play with settings a few weeks at least 4h/day. A monster of a BIOS on the DFI boards and very good on air overclocking.

I have quite a rare bird. The Gigabyte EP35C-DS3R with 4xDDR2 slots AND 2xDDR3 slots. Was my first ATX board off eBay in 2015. It is showing its age with the slightest vibration crashing the system.

The results were as I expected. Nice video anyhows:)

I have a p5q deluxe and am currently running 8GB of ram(2x4). The motherboard supports up to 16, but finding 4GB ddr2 compatible dimm's has been impossible. It would be interesting how a pc with 16gbddr2 would perform

This was interesting thanks Lga 775 was alot of fun. I've still got my old Q9650 on Gigabyte a EP45T-UD3LR mobo, oc'd to 4.06ghz with 16GB ddr3 oc'd to 1804mhz with a gtx 1660 running on my TV in my bedroom for rpg/survival games in bed with a wireless mouse and keyboard setup

Interesting findings with DDR2 vs DDR3 the issue with using DDR3 based LGA775 board is the price of these boards are pretty steep I got a X48 Asus board but it cost me over 200 USD I used the Q9650 CPU with the X48 chipset board, although the board supports 1600MHz RAM and above. it failed to boot with 4x2GB sticks of DDR3 1600MHz Samsung chip RAM which were taken out from HP OEM PCs I dont have 2x4GB sticks to confirm but will one day test it out with either a higher end CPU like the Xeon CPUs are try OCing the FSB pairing my Q9650 and 8GB of DDR3 with a GTX 960 4GB for some retro gaming

i just reassembled my old, first pc i ever built. lian li pc-a05, asus p5q-em, go q6600, ocz vendetta air cooler, 8 gigs of corsair xmw2 ddr2 800, western digital caviar 640gb, and a radeon hd7850. it originally had 4 gigs of ocz vengeance(?) 800 and a 9600gt, which i still have packed away in their original packaging. i was going to use those and just do a 32 bit xp build. but then i got it into my head to do a 64 bit vista experiment. perpetual upgraditis.

a lot of work on this vid, relevant for me in 2020 ! thanks :)

around here 2GB of DDR2 ram costs the same as 4GB of DDR3 ram and 2Gb of DDR3 ram are half the price of them in the used market so it all depends on availability, motherboards costs pretty much the same but DDR3 ones are a little hard to find these days... anyway for me it was time to say goodbye to the LGA 775 platform and embrace the 1155 greatness for W7 and XP era games

I think it you’d see a much larger difference with a heavily overclocked E8600 and fast DDR3 matched to the FSB speed. You could demonstrate difference by just lowering the ram speed in bios on one system . Pair with fastest graphics card to show bottleneck.

If the DDR2 takes CL4 at 667, then dual 667 vs 1333 FSB will be synchronous quad pumped, just like the early P4 with dual DDR400 - I had that, and it always felt quicker than similar systems that didn't have the same synchronization - there has to be some overhead where the RAM and FSB clocks are slipping in relation to each other. Now debating whether to replace my C2D E7600 3.06GHz with a Q9300 2.5GHz, or a Q6600 with tape mod... maybe a Xeon 771-775 hack, but it's an Intel board so modding the BIOS may be difficult or impossible (equally, has no OC options, so a Q6600 tape mod would have to get by on stock volts) Oh boy, the price of the top end quads is just silly, unless you want bragging rights for the fastest LGA775, it just doesn't make sense to go there

Ah, the old school synchronization thing. Memories of the early 2000s :)

As a game dev I wasnt expecting much of a differnece at all and I was correct. Look folks, a game loads its assets into the GRAPHIC CARD memory for future access lol the main memory is only used once or twice while loading assets from your drive.

Personally I'd just go with a DDR2 system in this case, the boards are much easier to find. That being said, the reduced power consumption of DDR3 modules is especially noticeable in laptops - ones with DDR2 tend to get very warm around the memory area!

Thanks for the video Phil, i know a lot of work went into it.I Think either Memory system will make a good XP Machine if the price is right.

Very interesting video. When i got my LGA 775 rig I had a DDR3 motherboard that was capable of 16GB of RAM being a P45 chipset but it didn't want to boot with 16GB for whatever reason maybe I needed to flash the BIOS in order for it to work properly or I was using memory that was too fast for it or something. Anyway when I upgraded from a Core 2 duo E8400 to a Core 2 Quad Q6600 I had to downclock my RAM 1333mhz RAM to 1066mhz due to the FSB on the Q6600 and I didn't notice that much of a performance drop and besides It made the RAM last longer. When you mentioned the chipsets running warmer it reminds me of the newer motherboards like for 4th generation core i series CPUs I had to increase the voltage of my RAM because I went from 2 stick of memory to 4 and it made Windows unstable to the point where I was getting blue screens.

I'd be interested in seeing this same test with an AM2+ DDR2 board and a AM3 DDR3 board. I have a spare pc with a Phenom II X6 1055t running on the AM2+ board with 8gb ddr2. Was curious what performance improvement it would have with ddr3 ram. The Phenom 2 and AM3 boards should have been far better designed to use DDR3 ram

Very interesting video ! I've had my P5B with 8Gb DDR2 for a long time and thought about switching (not anymore when I saw the prices for DDR2 (cheaper) vs ddr3 on AliExpress for 4*2 ) and I'm glad I kept my DDR2 ! The investment isn't worth it for me with my e5450. I have many old systems still on DDR2 (family) and prices are so low on Ali that it's not worth upgrading for just ddr3. A bigger step is needed for our uses (like X79 jumps)

Thanks for the tip, I keep that model in mind.

I went with a P5K Premium Black Pearl Edition as thats the board I had back in the day, 8GB of Corsair Dominator DDR2 1066 (5-5-5-15) as that was my original ram. I would have prefered the P5Q Premium as I have plenty of spare 1600 DDR3 sticks spare but they were stupid price and to be honest, I would rather use my old haswell system for XP than pay over the odds in that case. The P5K and 1066 DDR2 seems to work fine with the X5460. One thing I have learned though is keep the hardware for old OS support if your newer hardware no longer supports it, saves a small fortune in the long term and like my old Voodoo 5 5500 PCI, can be a bit of a cash cow as well if needed.

Remember that DDR3 at it's start was worse than many DDR2 dimms.

I have one of those oddball "transitional" motherboards that has both DDR3 and DDR2 slots, and a Q9450. There doesn't seem to be much difference in performance between the two!

Very interesting outcome! I would have expected there to be a slight bump but nothing too noticeable DDR2 to DDR3, but didn't expect DDR2 to edge out the later. Is this mostly due to timings? Looks like the DDR2 memory had lower latency? If I remember correctly I think Linus (Linus Tech Tips) did a similar comparison with DDR3 to DDR4 and noticed a slight but rather insignificant advantage on the DDR4 memory. Nothing that would warrant the extra cost though.

I got a 8gb ddr2 1200mhz kit and a 16gb ddr2 1066 kit, both worked Good on my p5q pro. Switched to the x58 Platform now, its a Huge difference.

I am curious about the results of the benchmark when you did DDR3 1600 vs DDR 800? This is a question that would be interesting. And also if there is any difference in brands in any of these era's RAM sticks to find a general pattern for example in types of performances on specific tasks. Thanks Phil

With socket 775, you would need Core 2 Extreme with 1600 MHz FSB to have compatibility with 1600 MHz DDR3 and these CPUs are very rare and expensive. Ofcourse you can take 1600 MHz sticks and overclock it to that 1600 MHz with standard Core 2 CPU, but I have very bad experiences with OC on socket 775 boards with DDR3 rams, it's just not stable.

oh man, color schemes on motherboards from these days were crazy. blue board, green and black IDE connectors, red RAM slots, orange SATA connectors, light blue pci-e connector, purple parallel port...

Ive been told by a couple of PC techs (builders/IT services) that ASUS boards are pretty much garbage these days. I do not know this from personal experience, but just observations from others. Excellent channel!

My gaming pc for many years (purchased used) was a ddr3 Intel motherboard with an X3370 3.0 GHz quad core CPU. It performed so strong I kept it through several GPU upgrades.

Great video, in the current health and economic problems, your videos on super budget PC upgrades are on the spot. If possible please add Cinebench R15 and R20 benchmarks.

For Motherboards, perhaps OEM could have been a option for something on a budget? I have a HP from 2007 with a ASUS IPIBL-LB (HP/Compaq name: Benicia-GL8E) that's a G33 Chipset with support for up to 8GB DDR2 (4x2GB) or a Acer/ECS G41T-AD that's a G41 chipset as per the name with 2xDDR3 slots so I would think 2x4GB DDR3 should be possible with the one I have from a Slim/SFF Acer Aspire coming with 2x2GB 1333MHz DDR3 though for 8GB I can get a 2x4GB kit of 1600MHz CL9 DDR3 used on local classifieds. For CPUs the HP DDR2 board came with a Q6600 though I had picked up a Q9400 that I planned to replace it with while the Acer DDR3 board came with a Pentium E6600 in it, i was planning on going with replaceing the Q6600 with the Q9400 for the DDR2 system and move the Q6600 to the DDR3 System replaceing the Pentium E6600 however thinking while watching this I'll keep the Q6600 in the DDR2 system and replace the Pentium E6600 with the Q9400 due to the FSB bump (1066 of the E6600/Q6600 to 1333) to get more out of whatever DDR3 I put in

When it comes to the DDR3 RAM, I'm not sure what the timing would work out 2 considering it would top out at 1333 but on my local classifieds there's someone selling a 2x4GB kit of Kingston HyperX 1600 9-9-9 1.65v though looking it up SPDs are programed to JEDEC standard 1600 11-11-11 at 1.5v, listed at $15 CAD, another option for something faster but less specific info for timings is someone selling 2x2x8GB (2x8GB=16GBx2=32GB in 4x8GB) Patriot Viper DDR3 1866MHz listed for $45 CAD. Then for $20 there's a 2x4GB Kit of Kingston 1600MHz CL11 (11-12-A1) 1.35v or G.Skill Ripsaws 2x4GB 1600MHz 9-9-9-24 1.5v. Edit: If I were to stick with 4GB instead of going up to 8GB (or 16GB), I should have a 2x2GB kit of G.Skil Ripsaws 1333MHz CL7 RAM around somewhere that could perhaps be used.

That means DDR3 is worthless on an LGA775 platform, good to know, now if only I can find a reasonably priced DDR2 motherboard with a max of 8 or even 4GB of ram to replace Foxconn 45CMX/45GMX with it, using only 2GB is very suffocating and sometimes I can't use more than 1 and it's killing me, my PC could at least breath a bit and I could finally move to x64 bit version of Windows 7 that I always wanted to use then jump to Windows 10, at least for while till I can upgrade with a much more modern hardware, I have 2x2GB DDR2 lying around for like 7 years that I can't use and I'm not even whether they're alive or dead, using this PC is very frustrating and the prices of those mobos just doesn't help. Any motherboard you recommend? That could be cheap of course.

Good video Phil. DDR2-1066 cl.5 is still the best for FSB1066 CPU's. (actually total latency wise, the DDR2-1066 cl.5 even beats the DDR3-1600 cl.9) On the FSB1333 CPU's, then I would prefer DDR3. FSB:RAM 1:1 is (if someone dosn't know) optimal on LGA 775. If you OC the Q9650 to 3.6GHz. @400(1600) FSB, then go with with DDR3-1600. A Q9650 @3.6(FSB1600) with DDR3 in sync = very close in performance to the i5-750 @3.6GHz. :)

Conclusion of the video is that if your processor is older like core2duo or core2quad, DDR2 and DD3 perform nearly the same. If the processor is fairly recent and quadcore and has a clock speed of 3 Ghz or more, DDR3 performs better. Nice practical explanation.
