A64 Overclocking Adventure...

[-=CrAnSwIcK=-]

i'm not doing too bad right now, so far i got 2.4ghz...and it ran 6 hours and 51 minutes of prime95...Ok, one question though, does the HTT bus has to stay under 2000mhz??, so any significant incease in FSB or CPU frequency, whatever we call it now, requires a drop in the HTT multiplier, right??

anyways, here's where i am so far....

It depends on your set up. Some have more success going past 1ghz HTT than others. I usually don't go too much over. I'm running 289x4 right now, haven't even tried 5x cause I'm lazy

oh right, it's 1000.... (2000MT/s) lol, see this A64 stuff is confusing me already...i got a random restart at 267x5 so i dropped it to 4...and haven't had any problems yet...

I am having stability issues around 2.6ghz...i haven't tortured it at 2.6 yet...but it dropped out of 3Dmark...so i clocked it back...and i even had to up the volts a bit...from 1.35 to 1.4 to get the 2.4....but in the reviews i read prior to this build showed they could do 2.6 on stock volts...

[omga14]

you can drop it to x3 without any performance hit at all so your safe if you need to do so for stability. i'd say keep it under 2000. doing damn fine with that cpu. i'm at 2.6ghz now with my 3700+(s754). stuck there cause the stepping's no good.

[saurongt]

I would suggest increasing the voltage to like 1.5v if you want to top 2.6. That's what i had with my 3200. The fact that others get good overclocks out of stock voltage does not imply that you will be able to do the same, it all depends on luck. Don't worry about higher voltages, just keep a close look at the temps.

is nTune pretty accurate with temps??

its just a generic software.......... i'd rather trust program rolled out by the motherboard manufacturer instead
And remember to put a memory divider.........

And from my experience, you probably hit the overclocking wall. My Winchester 3200+ could do 2700mhz (270FSB X 10) on 4X HTT @ 1.5V...............

And for my new Venice 3500+, i havent overclocked it yet because i'm too lazy to push the reset button over and over again

[-=CrAnSwIcK=-]

if i kick the volts up, i can hit 300mhz HTT...but i'm on stock cooling, so 2.4ghz is as high as i want to go for for now...

[evil_penguin]

well, I suggest u get a thermalright xp-90 or xp-120, and sme artic silver 5. artic silver 5 voids warrenties, but why should we care? dont get the xp-90c, it is more exensive, heavy, and doesn't work much better, by 1c. get a silent fan, I have a thermal take silent cat 92mm, but it sounds like the cat has whooping cough at 2556rpm. getting a after market cooler is worth it. get better cooling, it's quieter, and it allows for more oc'ing, like mine can be at 2600mhz, 11.5 *226 @1.54v (venice core) and my idle is 32c!

Arctic Silver does voided the warranty, but who's that idiotic to RMA a CPU with AS5 all over the processor?

Just clean it off with isophryl and all will be OK

As for heatsink, i'd go for Cooler Master Hyper 6+. Thermalright xp-120 are pain in the ass...... check the mobo compatibility before buying those.......

[evil_penguin]

they are only a pain if u have it in ur case allready, or memory installed, I had these paper cut like cuts all over my hands with it in the case ouch! the hyper 6 or whatever, is too heavy, but hey, it's your money and pc have fun

Hey guys,
Does any one know wats the highest that u core speed that u can get out of a AMD64 3000XP+.
Cos one of my mates got a new pc with a similar config to what -=CrAnSwIcK=- has and i could over clock it to like 1.92GHZ with a FSB of 240 and a multiplier of 8. and the HTT multiplier of 4. Oh yeah he running on a stock cooler still.
Wat would u recommend as good combination of multipliers and FSB.
Thanks

There is no AMD64 3000XP+. It's either the AMD Athlon64 3000+, or the AMD AthlonXP 3000+.

Think you have the 64 though.

There is not good combination we can really give because every motherboard/CPU is unique. They overclock differently. You "should" be able to get 2.4-2.8 ghz out of the CPU. However, it may not go that high or it could go even higher. The best thing to do is to raise the FSB(HTT) a few mhz at a time until it's unstable. But of course it's best to read the overclocking guides out there and follow along.

If you're running 1:1...i would set the RAM back to like 166mhz...and keep going...I would test all you hardware independantly...and find all your maximum clocks...my guess is your RAM is gettin flaky at 220mhz...so next i would drop the multi, maybe 8 is good maybe lower, but it's just to rule out the CPU as the limiting factor, set the RAM to a super low divider and crank the HTT till the mobo flakes out...then you'll know the limits of your mobo and RAM, and overclock your CPU accordingly...

Also is your mate's 3000+ a winchester or a venice core...you can check this with CPU-Z found here...this will give us a better idea of what you cn expect out of it...mine is a Venice E3...and does 2.6ghz with a small voltage boost and stock cooling...but i run at 2.4ghz @ stock volts till i get better cooling...But to answer the original question, i think they're name is the max clock...but i wouldn't go there...i think 2.8 would be as far as you'd wanna go...but not on air...atleast, i wouldn't

[-=CrAnSwIcK=-]

Ok, back to my overclocking adventure...ok, it's official...my VNF4 Ultra seems to be quite overclockable...as in, if i drop HT multi to 3x, i can hit 300HTT at 1.5 vCore and 1.6v chipset...i read the PC stats review on the board and they were only able to get 247mhz HTT...i'm running it at 267mhz right now...and i can go right up to 295 without touching the voltages...CPU requires a bit more juice at that speed...

[AMDnewbie2005]

Awesome, I'm very confident in my new rig now, Cranswick lol I've got the XP-90 and AS5 ready to go

[-=CrAnSwIcK=-]

Also...i got to doing some work on the RAM...but i'm kinda stuck...see the problem is everything runs great at 2.4ghz...but my CPU and mobo are quite friendly with eachother...so i wanna go higher right?? but if i go to 2.6ghz my RAM can't handle the clocks, so if i set the RAM down another notch to 133mhz...then i lose like a gig of memory bandwidth, cause the RAM will still be under 200mhz...like 170 some...so what i'm thinking is i should just go all out and do like 300 HTT or more...say like 311...which would give me 2.8ghz...or go even higher and set the set a lower multiplier...BUT, i can't seem to find the option to change the CPU multiplier...like it's not there, i've check a bazillion times...but i know it SHOULD be there...cause it's even in the manual, and all the reviews...

[-=CrAnSwIcK=-]

This is with all 4 sticks in (1.5gb), @ 218mhz in 2T mode (cause 1T doesn't work with 4)
[IMG]****************img507.imageshack.us/img507/781/218mhz2t15369pq.jpg[/IMG]

And here's what i get with 1gb, @ 218hz in 1T mode..
[IMG]****************img515.imageshack.us/img515/9411/218mhz1t10249wj.png[/IMG]

when i run 1024mb in 2T i get a little bit higher than the 1.5gig in 2T...but both the 512 and 1024 kits running by themselves in 1T score about the same...with the 1024mb taking the cake at just over 6gb/s

[rottenotto]

gotta hand it to ya , bro---- yer pushing the envelope on unconvention. Keep up the good work, and hope you don't fry anything ( fingers crossed).

[PCgeek]

Dude what timings are you running on that RAM cause my Bandwidth is so much worse than yours...

1.5 GB ; 220MHz ; 2.5-4-4-8 ; 2T = 5063 MB/s vs. your ~5100MB/s @ 218MHz

1 GB ; 220MHz ; 2.5-3-3-8 ; 1T = 5862 MB/s vs. your ~6200MB/s @ 218MHz

You're kicking my ass tell me ur secret lol.
