930 or 805 ??

[rgold28]

Makes me think about an issue i need help with. Want to convert all my desktop PC's to Conroe, but waiting for the price to become reasonable. So staying away from the dual cores now. A guy is selling an Engineering Sample Conroe on eBay for $850. Wonder if Intel is going to tear him a new one.

hey, to the guy who essentially said that single cores are crap, they generally are able to overclock higher than dual cores...... just look at the whole cedar mill series

I'll take a dual core at 3ghz over a single core at 3.5ghz any day of the week.....period. In any multithreaded app, that dual core will smack the single core around like a cheap whore on a friday night in Vegas...


Don't forget, Windows XP is indeed multithreaded software...

 

[fan_83]

so according to MC, its either a 805 that can get to 4ghz or a 930, with a N18 can only reach 3.3 ... hmmm

tough choices.. does anyone else have a 930 and is willing to share their settings and mobo that allow them to reach over 4ghz??

 

[ChronicTrees]

You could hit 4 ghz with an oldschool northwood if you are [H]ardcore enough. However after seeing Yonah, Conroe and Merom, some would see it as a waste to spend a penny on anything else at this time. At stock speeds they rape my processor at 5.5ghz Maybe not rape, but it's freaking amazing.

 

[MC FLMJIG]

The 930 can go MUCH higher but from what is seen just not on an NVIDIA chipset.

 

[viper650]

Go with the 930 (it OCs very well, while running cooler, requiring less juice, has more cache, and a more advanced cache access system, clock for clock a 9xx chip is faster than a 8xx chip) and put it in an Asus P5WD2-E Premium.

Why the premium board? 975x chipset, it's worth the extra money. This is one of the two motherboards based on 975x that have been confirmed to work with conroe. So, when the 930 isn't cutting it anymore, all you have to do to upgrade is pop in a conroe CPU in its place, and everything is dandy.

this is a complete and utter lie. unless something was released in the last 12 hours, there are NO current boards out besides the intel bad axe with rev whatever403 or something like that, that will support conroe.

higher clocks dont necessarily mean higher performance... it took 4.9ghz to reach a 28s super pi for me on a cedar mill, my presler can do that at 4.3ghz.

930D, p5wd2 premium ocz gold 2x1gb ddr2-800
vcore set to 1.3875
ram set to 855@5-5-5-12 timings(best performance, can go higher if wanted to)
fsb set to 285 pcie 100/33.33 um i think thats all i changed. im sure if i tweaked it more, i could get higher. i have hit 4.5ghz stable, but the board i have droops way too much and im not comfortable going any higher until i decide if im selling this computer or keep it and vmod it.

Hey, Viper, what HSF were/are you using?

but if you're paying for electricity, you're going to be sorry

Dude, I've honestly heard enough about the whole electricity bill bullshit. People just don't have a clue. Current national average rate for electricity is $.10 KWH (that's kilowatts per hour). So basically, if your computer puts out 500 watts (which is a lot, would take a very highly OC'd system), you're paying a whopping $.05 per hour. 8 hours a day (again a lot) X 30 days = 240 hours per month. Yup, $12 a month. Don't know about you all, but if you can afford a pc that puts out 500 Watts, you can prolly afford $12 a month in electricity to run it...

 

[MC FLMJIG]

975 mobos support conroe

 

[viper650]

975 mobos support conroe

no, no they do not. only one is the intel 975bx, and it must be revision 304.

 

[messerchmidt]

get the nforce4 sli intel edition with a 930d and some ddr2 ram and your golden

 

[MC FLMJIG]

Only if he doesnt want to OC

Nvidia chipset is not good at all to OC.

@ least not the ABIT NI8

Truth. If you can't afford $12 a month for your PC power needs, you prolly should not have a high end PC in the first place, the $$$ would be better spent on food for the kids, education, home, etc.

thanks viper but I have a question: why oc ram?

cos from what i have gathered, a 1:1 is best but you seem to have gone 285:427.5
2:3, wouldn;t underclocking it to 1:1 work better?

if at 4.275ghz is the limit for a p5wd2 premium, then my 4.5 goal seems a bit unrealistic unless you were a bit unlucky...

1:1 isnt always best. perhaps if you are running a ddr rig, then 1:1 would work quite well. however, you always want the highest it can do stable, right? with the ddr2 800@ 885, i see nearly 400mb/s difference in sandra bandwidth test over the stock 400mhz. it does make a noticeable difference. if i was to run this ram at 1:1 ratio, i could get this to do timings of 3-3-3-6(i got bored and tried it) but timings dont really affect the bandwidth like mhz does. i scored only 5500 mb/s in the bandwidth test. obviously higher is better.

4.275 isnt the limit for the board, it just offers the best daily performance. ive seen 320fsb and something like 4.6 ghz. im just not willing to crank the vcore up any higher then 1.4375 for daily use. i dont want to kill my chip either. remember asus boards have a nasty droop, which also effects how much vcore you can give it.

viper so if i am understanding you courrectly, it doesn;t matter about the divider, but i should just try to oc my mem as high as possible. and that as long as its more than 1:1 i will see performance gain instead of a bottle neck.

i want a 4.5 with good daily usage.. i plan to use the comp for at least 2-3 years, turned on most of the time.. so if at 4.275 is the best stable speed on can get with a margin of safety built in

also regarding the power cost thingy... i find most of the high cost calculation supporters argument a bit flawed... they do not consider the fact that for your comp to be drawing such huge watts, it has to be turned on before you even oc it..

your standard 805 draws around 90w i think( not sure) and when oc , draw to around 200 (toms hardware i think)
thats only an increase of 110, so for an hour worth of oc you will be charged 0.01, using 0.1 as kwh
assuming a nice 12 hours usage: thats 3.6 for a month..

they seem to be ignoring the fact that once they oc, the huge 500w pull is only due to oc but its due to the system that they have

therefore shouldn;t it be concludable that ocing is a negligible cost from power supply point of view ??

i dont know why everyone keeps babbeling over power bills, mine has never been higher then 32 bucks in a month, and thats when i left my ac on all day while at work doh'

intels dont really care about tight timings, they like higher mem frequency's. so yes, if you have ddr667 and you have been running at 1:1, you are seeing a HUGE performance loss unless you are running an fsb of like 320 or something. now dont forget that at a certain point, your ram will stop gaining you performance, and become unstable and actually hurt your performance. i can run 450mhz, but the performance gain of 428 vs 450 is 400mb/s, despite the higher clock. it really just takes you playing around with the settings, and running benchmarks. run sandra, its a great way to test for a baseline of where youre at, and how your increases affect performance.

i can tell you right now, if you dont do much but email and web surfing, 4.5 is overkill for daily. its really hit or miss with these chips, mine will do 4.0ghz on stock volts... STOCK 1.28 in bios. thats awsome... but it takes a lot to get to 4.5. 4.0 is more then enough for day to day stuff.

 

[fan_83]

so from what you are saying is that in ddr2, the divider don;t matter as long as its more than 1:1.. hmm i will try to max out my ram then and score it..

but it takes ages to do a proper series of tests .. can't someone come up with stability tests that takes less than a couple of hours to run
