uh...wheres the review..

What's the Pentium-D equivalent? 5+ GHz?

I am sorry to say but that's not an equivalent. You can make eggs over easy for breakfast with a P-D 5ghz and it won't complain and AMD just deprives us from this satisfaction.

This is a tremendous overclock Elfear. How is 520W Powerstream holding up?

I have a 420W version myself and looking at specs Bottom page:

420W = 3.3@28A, 5@30A, 12@30A
520W = 3.3@28A, 5@40A, 12@33A

Since today computers rarely rely on 5v rail, it seems that 520 and 420 are very close in theoretical performance. I was wondering if I got a new setup, if it would be sufficient? I mean looking at the wattage rating it seems pale wrt to latest PSUs, but for today's demand on 12v rail it seems sufficient no?

Currently waiting on a motherboard that will do 330+MHz on the fsb so I can get some stability shots for you guys. Hopefully that will be in the next week since DFI will be releasing their RD580 board on the 10th I believe.

Thanks man. I also noticed that the 12V rail on the 420W and 520W models are very close, which is really what matters IMO. You should be fine unless you decide to go Crossfired X1900XT's or SLI'd 512MB 7800GTXs. Those will lay waste to PSUs previously thought of as very good. You did future proof a bit though because it's a single rail psu.

Sorry to drag this old thread up but I thought I'd post an update and a screenshot.

For some bizarre reason my board decided to miraculously start working. I can now boot into Windows at fsb speeds above 320MHz. I've got it stable (dual SuperPi 32M) at 3.04GHz@1.55V so far. Hoping for 3.1-3.15GHz bench stable when all is said and done.

3.04GHz@1.55V

hey nice overclock..
about your HTT
raise your chipset voltage. to like 1.7 and the LDT to 1.5-1.4 and see if it solves the problem
if not you can revert to stock . but it should help a little.
i find it nice to up the chipset to arount 1.6 (what i use 24/7) and LDT up a notch

Ya, if you look at the screenshot I've got the LDT voltage at 1.4V and the chipset voltage at 1.7V. I seem to be limited by the chip now which is good since I won't have to spend any more money on a better board. Looks like we have pretty similiar rigs.

Nice overclock elfear, best 165 i've seen.

It's a CCB1E 0550 VPMW I got from Monarch a few weeks ago.

I'll try and get some screenshots later today or by this weekend. School has been crazy so I don't have a lot of time right now but I will post something up for you guys.

D00D! You and me have the same stepping!... Too bad I'm on air... But I'm going for 2.9 GHz

Thanks man. I know Lopri's got the same stepping but it is a bit better than mine.

You have a very nice 170 by the way. 3.15Ghz is amazing in and of itself but it's even crazier that it's Prime stable at those speeds.

That stepping has been clocking very well so you should be able to hit 2.9GHz without too much trouble.

 

[lopri]

Congrats on your achievement, Elfear. I just saw this somewhat old thread and very happy to see you finally achieved the magic No.3! You should be proud of yourself.
What was your previous board (I'm seeing your current one as DFI Ultra-D)?

What stepping do you have and where did you get it?

 

[designit]

Nice overclocking. But you need to reduce the SPi time. 27.17 is a bit high.
I have got Venice 3000 @ 2.7 Ghz do 26.50 . Not intending to downgrade your good work, but a hint. maybe need to play w/ dividers. Dont go by 133/266, 166/333 etc... look @ cpuz and see how it's dividing cpu/mem ratio and you may find out that 166/333 could be used(if you are now using 133/266).
let me know if you need help w/ that.

 

[Shimmishim]

27 minutes is a bit high but i think that's mostly due to what divider he's using.

superpi is very mem dependent. also running dual superpi 32M vs. single superpi32M will result in a slower time. im not sure why.

i've tried dual 1M on a opty 170 vs. single 1M on a opty 170 and i got better results running just one instance.

so it's not a surprise your venice actually does better times.

Funny that my dual core chip can now run as fast as my old venice did And with less volts

Can't wait till I can get this X2 under water... when I feel like putting 1.5+ volts into it, there is no doubt in my mind I'll get close to 3 Ghz.

Still using the same Ultra-D. I have no idea why it suddenly started to work. The only thing I've changed is the ATI drivers. Might explain why I was able to boot into Safe Mode and run SuperPi no problem the first time, although I have no idea why the graphics drivers would limit my oc??

I'm on a 133 divider right now which puts the ram at 220MHz with 3-4-4-8 timings. I'm sure that's why the SuperPi times are a bit high, that and what Shimmishim mentione with the dual instances.

I haven't had a chance to test with a 166 divider yet. I don't think my ram will do 280MHz so I don't think it will work. I've had problems in the past with the odd dividers (140 and 150) using an Opteron, so I might be limited to the 133.

What stepping do you have? The newer X2's have been doing really well from what I've seen. Right around 2.9-3.0GHz with really good air or H2O.

 

[designit]

Right now, probably your cpu is using 14x 217.28 because 13x will put it over 133 divider (3042/13=234), so that means your actually using lower than 133 divider(128 to be exact). If you use 166 you will be able to put the ram @276.5(276.5x11=3041.5)
if the ram can't handle 276, then use 270, or even 260 to get: 265x11=2915/9=323.8~323.
I bet @ 323x9=2907, you will have better score, the ram @ around 264. I believe those Gskill will clock as high as 270 mhz if I recall.
play around w/ 166 divider and see what come up w/. we know you can do >3ghz, but now the whole purpose is fine tunning it to get better scores.

errr...

he has an opty 165. the highest mult is 9x.

so it's impossible for him to run 14x217.

he can't do 13x... he can't do 12x.. he can't do 11x... he can't do 10x...

yeah...

 

[designit]

shimmishim, I am using cpu/ram divider. the one that cpuz shows in memory section.
the bios dividers(100, 133,166,etc...) are not exactly how cpu divides it's cpu/mem ratio.
it has to fall to nearest integer (no fraction). those # i showed represent that, not the cpu multiplier, and are correct.

Where did you read about high X2 OC's?

Good job on the SPI, but lets see u get dual prime now!

CCB1E 0550VPMW is a hit-or-miss stepping. Not as consistent as, say, 0530TPMW or 0546XPMW, etc. Some chips will clock extremely high (like Elfear's), but some will not be as good. My observation on this stepping is:

1. Excellent clocks @low volts. Many will do 2.6~2.65GHz @stock or near stock vcore. Perfect stepping for people who wants a cool, quiet system. Basically it's like a stock FX-60.
2. If you're not lucky enough to get a chip like Elfear's (which is very likely ), you might hit the great wall around 2.7GHz.
3. The 2 cores might show extremely unequal behaviors. For example, core 1 can go up as high as 3GHz but core 0 will not even do 2.75Ghz, etc..

Elfear's chip is one of the golden, magnificent CCB1Es. But in general I think this stepping is somewhat defective. (Well, if you could call it that, lol) I'm not saying that 2.6GHz @1.31V is bad! I'm talking about the manufacturing for this stepping and the pattern of chips performance/clocking behavior.

Elfear, what is the batch # of your CCB1E? The first 3 digit numbers right after "L" on the 3rd line of imprint. I'd much appreciate it if you could remember.

These days it seems like dual-core CPUs clock higher than single-core CPUs. lol.. Congrats again on your extraordinary achievement, Elfear. I don't think we'll see a retail chip faster than that till next year. FX-64 for $300! Holy!

Edit: Spelling

This is EXACTLY what my 165 has done for me. 2.6GHz @ 1.45v. Hit a wall around 2.7-2.8 and core 1 would always keep going long after core 0 would fail. I didn't bother to see how high my best core could go because I don't like to tease myself with "what might have been". Granted I'm VERY happy with the price/performance, and am just a little jealous of those who have virtual FX62s or 64s, I'm stuck with my FX60 ... lol. Although to be fair, the FX60 can overclock too, I don't like to boast about how my CPU is as good as an FX60, because it definitely is not - as FX60s can overclock too...however I'll "gamble" and save my $800 everytime.

Hmm... I'm right now at 2.908 GHz with 1.475v... Not sure if its stable, but I'm still tweaking... I'm not sure if I want to push 1.5v... 2.8 GHz only required 1.4v...

Looks almost exactly the same as mine. 2.8GHz@1.4V is dual Prime stable which is what I use for 24/7 use. What cooling are you using? 1.5V isn't bad at all for good air-cooling.

I'm using a 92mm 27 cfm/19 dba 92mm nexus with a xp-90... But do I really want to push 2.9 GHz?... that's the question.
