Opty 165 or Pentium D

[jayanath]

i was considering of buying a opty165 for OCing instead of pentium d @ stock. so what do u guys think i should get.. if Ocing i need to do it using software not in the bios...
so any thoughts guys?????

Not even close, Opty 165. Even at 2.5 it will best a PentiumD@4.2, and you need phase change to get that, where the Opty will do 2.5(alomost guaranteed) on stock air cooling, and may go as high as 3.0 on air (not typical)

 

[jayanath]

so which software can i use

 

[Markfw]

Why not in the bios ?

 

[jayanath]

i dont know why but software sounds safer than bios

 

[Markfw]

Bios is way too easy for an easy OC. Just do it. Especially with the Opteron, just set a memory divider, and set the fsb up to 250-260 and you are good to go. Oh, and a little vcore (not a lot)

 

[jayanath]

i understand how to change memory divider but what i dont understand is the Vcore..what is it,what does it do and what do i do to it

 

[Markfw]

vore is the voltage for the cpu. You raise it a little. Without that you can't OC for anything.

I agree with the opty 165. While you wouldn't likely actualy need phase change to hit 4.2ghz with a Presler, you would need very good air cooling, and an expensive motherboard and some luck as well. The best I got mine to was 3.7ghz(before one of the cores died), and it didn't come close to performing as well as my X2 @2.6ghz. My second 920 is only @3.4ghz so it's even farther behind my X2. Also, it's easiest to just do the overclocking from the bios. Software that lets you overclock tends to be lacking in options, you have the best options right in the bios.

EDIT: Here is a link to Zebo's quick and dirty overclocking guide, that should help you out quite a bit.

how come i cant change the vcore in my current processor its a P41.8ghz the max i get is 2.0ghz. the vcore option is not accesible in the bios is this why i cant go above 2.0ghz

 

[Markfw]

Because its a dinosaur, all the new ones let you do that.

 

[jayanath]

yup its fossil alright
anything i can do to unlock or override or somethin

My two cents: It depends what you are going to do with it. Just got the 805 Pen-D and will be building a rig for video encoding this week. I'll still have my AMD rig for general usage but from what I've seen so far, the D is unbeatable for encoding at a measly $130. If you are only going to have one rig and it will be multi-purpose, the 165 is likely the way to go.

 

[jayanath]

yeah i was considerin the 165 what bothers me is its 1.8ghz stock speeds

Get an X2 4200 then @ 2.2GHz. It's slightly more than the 165, but you get a much higher multiplier.

Pentium D's...
Smithfield :thumbsdown:
Presler :thumbsup:

Wow...Just wow...

Where to begin pointing out your ignorance...

1) It takes an AMD at 2.6-7Ghz to match a P4 at 4.2Ghz

2) 4.2Ghz DOES NOT require phase change. Trust me on this
I've been running at 4.2 for three months now...

Dude, don't even stress those stock speeds, I thought the same thing with my Opty 144, so I shopped around for good steppings found some, and have my CPU to 2.9 with a crappy Corsair Value select 1gb kit. (my OCZ 2gb platinum is on its way) after my OCZ comes in I'm expecting at least 2.95-3.1ghz with 1.52vcore 49c load temps

GO FOR Opteron 165 all the way

EDIT: Pay $20 extra to have someone else test the OC and buy it used.. my 2cents

He was wrong about the phase change, for Presler at least, smithfield is another story. But since I own an 805 a 920, and an X2, I can tell you that it does take 4.2ghz on a pentium-d to match a 2.6ghz 512k cache, or 2.5ghz 1mb cache X2 in most things. There are a few programs where the pentium-d starts pulling ahead around 3.8ghz, but primarly, 4.2ghz is required to beat the X2.

Wow ! First, I have both and have benchmarked them. It depends on what you are running but my statement is true, and I posted the benchmarks back when I got the 820D. On the phase change, I was talking 8xx, not 9xx. If you know anyone that has a 8xx (805 or 820 specifically) that runs 4.2 on any kind of air, please post link.

As to telling me I am ignorant, since I own them and know of what I speak, and you don;t, well figure it out, and thanks for the insults. I got banned for that, but since I don;t PM a mod every time some ignoramus posts, I will just end this here.....

X2 4200 hmmm ive got to check the prices

You've benchmarked a 920 at 4.2Ghz? Nope. I rememeber your threads.

a) You had an 820, not a 920. The processors perform differently at the same speed due to cache size differences.

b) From what I remember of your posts you got your 820 nowhere near 4.2Ghz so your comparisons were nothing more than extrapolation.

c) On the phase change, your fault for not specifying. You gave the impression that it takes phase change to get an Intel D up to 4.2. NOT the case.

I have a 920, 805, and X2, and had an 830 as well...his description is pretty accurate, 4.2ghz will equal around a 2.6ghz X2. There will be some programs where the Pentium-D will pull ahead before that, but for the most part 4.2ghz is needed to match or pull ahead in a majority of programs. Most programs are not very cache dependant either, so the cache differance between the 820 and 920 means very little in a majority of cases. My 805 and 920 compare very similarly at 3.7ghz, despite the cahce differance, and FSB differance. The main differance I see between the 8xx and 9xx series is the amount of heat generated, the 8xx series runs a lot warmer.

My only points, besides the phase change misinformation, were:

1) The people making the comparison between their AMD's at 2.6 and the Intel D' at 4.2 have not actually gotten their Intel's to 4.2, or in Marks's case were using a 820 to extrapolate 920 performance. Nobody that I've seen has been able to do an apples to apples comparison.

2) Cache size difference does make a substantial diference in the only apps I care about; Games. The D920's outperform their 820 counterparts at the same clock speed consistently.

You should also note that your 4.2GHz on air isn't very typical either.

Well then maybe you should go buy an X2 so you can see it for yourself, I don't see you being able to do an apples to apples comparison either..I can tell you that at 3.7ghz, the pentium-d's still lag far behind the X2 @2.6ghz, which is more than you can say having nothing but the pentium-d yourself..and going by the numbers I get at differant speeds, 4.2ghz is a very accurate prediction of what is needed to catch the X2 @2.6ghz..maybe if any of my 4 differant pentium-d's were able to make it to 4.2ghz on a reasonably priced motherboard I could give you an exact comparison, but why would I want to spend twice as much on a motherboard to get the performance I already get with my X2?
