whats better for ocing the 754 or 939

[rpmcrash]

I just dont understand why the 754 sigs look better than the 939. Is there some kind of performance hit
the 939 is getting when ocing . their is people posting claiming how much better the 939 is over the 754
and their o.ced numbers dont evan compare to the 754 numbers.

I think you need to go look at a 3000+ 90nm part and see the margin of overclock you can get. From what I saw, it is a very nice part. The parts will further differentiate themselves in the next few months when the next stepping 90nm parts roll out. Then it will actually make sense to buy something faster than a 3200+. I really think the differences lie in the dual channel memory access, MBD silicon, and HT speed modifications. As we see valid second and third revisions of motherboards, the 939 may look to gain ground. What do you think?

I think that dual channel 939 is the only edge it has over the 754 right now im running a vnf3-250 3200 +nc 2.55 ghz [255x10] 1.6v.
ive had this oced in 280 but on a stock heat sink it was running a little hot so i kick it down to 255 again and i order a water cooling kit.
what do you think would happen if you put dual channel on a S754 board how much of a gain would the 939 have then .

I could be brain dead for even thinking this way .

You can't put dual-channel memory on socket 754. Remember, the Athlon 64 has its memory controller on the chip. Changing the socket and the motherboard chipset will not give you a better memory controller.

You can put nice stuff like PCIe, etc on socket 754(with nForce 4 will do, apparently), but you'll still be stuck with single-channel memory.

If you put dual channel on a 754 board youd have a 939 (with different socket) The only diffrences I have seen are the dual channel and lower voltage/heat. 754s have faster default clocks and hotter running, more voltage (electricity in San Francisco is not cheap and my bill actually went down 20$ this month since I have installed my winchester!) and more 754 mobos at the moment. A choice between the two, I can't see why to not get cooler chip with dual channel. Plus 754 is dead end it seems -no dual channel and there are awesome 939 OC boards getting cheaper evey day.
939 is cooler and has dual channel mem controller on-chip. why would 754 even be something to look at since the prices are the same now?
GA-K8NS Ultra-939 OC's with ease like my old NF7-S rev 2.0 115$ Whole lot more features too. -recommended with 3000+ 2.55 on stock air.
754's look better becasue they are more mature. I am afraid 754 is not going to be the focus of AMD anymore with obsolete mem controller on-chip though.754's still kick serious ass but I couldn't see getting one right now knowing I have mem ready for dual channel. yeah it might be just a step better then a gimmick but hey if you don't want gimmicks you could always get a celeron with integrated video. As for me more features the better when I am buying new technology and thinking about the future.

the way i see it i will keep my 754 for now overclock the hell out of it . learn more about useing diffrent multipliers then get ready for the
ddr2 939 sli board to come out in 2005 may or june the way things keep changing . keeping up can put a strain on ones pockets.
Im not into gimmicks . plain and simple is what i like . as far as the celeron i might need to try some of what your smoking to understand it.
thanks for comments. and i hope my threads will get better in the future.

if u could get 2.8 GHz stable out of a chip with water cooling i wouldnt bother going to skt 939 for more oc'ing!

And as for Steeplerot, i just ordered a skt754 3400+. I dont see what you mean when u say prices are the same. This is as fast as a 3500+ and cost's $50 less. The DFI board that i ordered also is probably the best mobo to date.

Also, i hate people saying "i'm buying skt 939 so i'm ready for the future!" By the time ur processor is too slow, the new socket is gunna be out most likely, and i'll have my extra $50 to put towards that new board! I'm thinking about the future too....

Dual channel is nice, yes, but the extra 200mhz on the skt754 also has it's benifits.

I'm not saying skt 939 is bad, but skt 754 processors are gunna be fast for just as long as a $50 more expensive skt 939 processor.

The selection of value overclocking s939 boards is nonexistant. I'd like a board that doesn't have raid, dual lan, firewire, and other crap I don't need that jacks the price up $50.

I'm waiting for a DFI infinity/Abit NF7-S/Shuttle AN35N Ultra type of motherboard for s939.
I'm only wanting to get a s939 board because of the winchester chips. Otherwise, I'd grab a s754 3000+ and throw it into an 8KDA3j or DFI Infinity.

Agreed, although want PCIe

some say the 754 board will be dropped . then i hear a new 754 NF4 board with one pci-e slot will be
comming out soon. That works for me because i wont be looking at empty slot like with sli thinking i
would have to fill it to get max performance. a 754 NF4 BOARD wow that would be a value board with some muscle .

Check out Madshrimps for two reviews that show the 754 is ahead of the 939. On a DFI mobo, you can run the FSB up to 360 and memory up to around 305 with one stick of ram. Hard to beat that.

If you visit the hardcore overclockers forum XtremeSystems.org you will see that the Winchester cores seem to have problems with their memory controllers. What is meant is this... my NC 3000+ can hit 297 fsb all day on air, other NCs are up in the 300+ range. The WC 3000+ cant seem to reach that high of fsb. If the WC could do high fsb speeds it would kill the NC but it seems it is not able to ramp that high. Also, the WC controller doesnt seem to like the tightest timings such as 250 fsb at 2 2 2 0 like the NC does. It is a big crap shoot. I prefer the NC at this point as I was able to buy my 3000+ and my DFI UT 250 that gives me 2.4Ghz and right at 300 fsb every day on air cooling for less than $275.
