value overclocking

When I overclock, I do it not to have the best and fastest system, but to maximize the bang for my buck. Don't get me wrong, I'm interested in having a fast sytem, but I would never for example, by an Athlon FX just to have the unlocked multiplier.

So I have recenlty begun to think about building a decent system around based on an Athon 64 value overclock. On the other hand, I really would like to look into a 939-based Nforce 4 system because I want to get a Geforce 6600 GT AND I like the idea of Native Command Queuing for my HD. Are the desires for overclocking value and platform features incompatible? I feel that the 754 vs. 939 complicates the situation when it comes to overclocking as well. As we have seen, the 90nm 939 3000+ overclocks very nicely and I would be pretty happy to get it to a nice and conservative 2.4 running at 266 fsb. I also understand that I can probably get the same speed out of a 130nm 2800+ on 754. Furthermore, since pushing HT past 1000MHz seems iffy, I would probably have to set the HT multiplier to 3x which gets me 800MHz. This is perfect for 754 but underclocked for 939; not sure if it matters. But what might matter is the fact that 939 has double the memory bandwith. I'm not sure how much of a difference it makes at clock speeds as low as 2.4, but I'm sure it will be more important as clock speeds scale up. Also regarding memory, I have been planning to get value PC3200 at CL2.5 to keep costs down, and just use a memory divider to get ~200 MHz. I figure that I will get at a minimum, the same performance as a stock system clocked at 2.4. I understand that spending more money on faster memory helps because latency if effectively reduced (bandwith is maybe not so important). One more thing I'm worried about is that for 754, I think that means that I will have 2 memory modules (2x512MB) loading the memory bus so I may have to set the command timing to 2T and I know that this kills performance. This wouldn't be a problem with 939 because there is only 1 module loaded on each channel.

So, what do I do? I'm pretty set on getting a value processor, but the other variables are 754/939, AGP/PCIe, value/fast memory. I'm not exactly sure how I want to prioritize bang for my buck vs. platform features and future upgrade potential. I am ALWAYS torn between the two. There never seems to be a good combo that hits both of these goals. What is recommended for each of these goals? IS there a reasonable compromise?

I'm pretty set on AMD. I play games. I'm an engineer and I respect the philosophy behind their design. I'm am also a Red Sox fan, so getting behind the traditional underdog is in my blood (especially when the underdog is the better performer). ;-)

939 and value do not belong in the same sentance no matter what you get.

It's $340 minimum with HSF. You can get a 2800AX BOX a chaintech VNF3-250 mobo and farcry game from mwave.com for $202 and overclcok this to 2400-2600Mhz with indeserable speed differences.

Yeah, mobile bartons are great overclockers but there only as fast the slowest K8's in games.

Forgot to mention, I also like to keep the noise down. So I was thinking about going with a K8 Silent Boost instead of the stock cooler for whatever processor I buy. I also have bunch of panaflo case fans that I can use. I'll need a solid but relatively quiet PSU as well; something capable of powering a 6800GT/ULTRA if I want to get one cheap in a year or two.

My mobile @ 2700 = my A64 @ 2200 aka 3200A64 in games but ingeneral I agree, for gaming, A64 should be your only choice. And at $200 there is no excuses.

Good quiet cooler. PSU = Super Flower 140mm fanned varity. Same build as Enermax IE high powered 12V rail but silent due to fan size and low rpm.


Model NO: SF-480T14 or above.

Dude you are in a for rude awakening and lesson on noise with this 6800 stuff and trying to overclock. The little 60mm fans or blowers on these new cards are insanely loud. Overclcoking CPU with even the "silent boost" will not net you anything unless you crank fan rpm to noticable levels. But we all have different tolerances. If I can hear comp I have issues. I'm old and have brats so I'm a bit testy anyway.

I moved to water cooling a long time ago for this reason. Silent and high performance.

I don't think silent boost fan speed is variable. Anyway, based on reviews from newegg, it seems to be more than sufficient for cooling a 2.4 GHz AMD64. Regarding the video card, I was planning on getting a 6600GT and I hadn't planned to overclock it (unless its overclocked stock). Remeber that I overclock because its something for virually nothing, the part is capable of the higher speeds (while still running relatively cool) but it is badged as lower speed. I get the feeling that the Geforce 6 video cards are stock clocked pretty close to as high as they can go because of the excessive heat. Since you can't seem to overclock them too much without expensive cooling solutions, I would guess they are heat limited. Anyway, if video card noise is really bad, I can always get an NV silencer.

Does using > 1 DIMM on a 754 board require setting command rate to 2T?

presuming that you have a CG cpu, than no. many C0 will require it, though.

That is pretty incorrect. A fast enough mobile barton, say running at 2.8 ghz, is actually faster in games then a stock AMD 64 3200.

There isn't as much difference as you think. Been a lot of tests done between the processors, and lots of articles written on it.

The Sempron 3100+ has proved to be a great overclocker, reaching 2.4GHz, which is almost a 40% overclock.
the DFI LanParty is a good mobo match for this CPU

754 doesn't give up much to the more expensive 939 platform. The integrated memory controller trumps the dual channel most of the time, making the two perfom very similar. With value in mind, this may affect your decision

I say 939, the price of 90nm 3000+ will drop to 150 oem by end of year I bet, and with 130 dollar nforce 4 board you will be getting a much more future resistant fx-55 level performance for 280 if you will OC. I say that is bang for your buck because it will play future games better.

Edit: Not to mention, as new games will require massive amounts of ram, and 754 dont perform well in memory category with >1 dimm, that is a perfect example of the future resistance of the 939.

Are you kidding? You are telling someone talking about buying athlon64 to consider celeron? XP's stomp all over celerons and A64's stomp all over XP's. Tell Pat you'd like to buy a clue.

Umm, no.

CG allow it, C0 are ALWAYS at 1t. Going much above 200-220mhz @ 1t with more than 512megs ram is quite hard in my experience
