Oh really, that is interesting as hell. The games are changing to take advantage of multiple cores??? Wow!!!

So I think I finally understand your post a couple back.

The Pentium D is the dual core version of your processor, so not only are there two cores, a 1.86Ghz Core 2 duo core is like a 3.6Ghz core!
Consequently, since the 2.66Ghz E6750 is now dirt cheap, you can get a cheap CPU that's effectively like a 5.2Ghz dual core version of your CPU!


When you say "it doesn't need 64 bit to kick ass" you're meaning is that it doesn't need 64 bit software, isn't that what you are saying. It is a 64 bit chip, right, they all are now, right? (Remember I know even less about cpus than I knew about fans a week ago.)

I did a quick google on the E6750. They're selling the 2.66 E6750 for about $200. That outperforms the 1.86 core 2 duo, which benched similar to the pentium D at 3.6Ghz. It outperforms in the ratio of 2.66/1.86. So, take 3.6 and multiply it by 2.66/1.86 and it would be like having two cpus, each one running 5.2Ghz, compared to my one cpu running 3.2 Ghz.

Yeah, fast!

Do you still prefer AMD. I read that they are extremely price-competitive and everybody has great offerings under $300.

Travis, I need your help, and you're the perfect person still here in the agp world with me. So are you off the meds enough to help me out? I hope you're feeling better, btw.

Sam was answering my question about putting more memory in my computer, maybe another stick. Several posts up I was asking:
Quote:
My memory is DDR2, known as DDR400, 400 Mhz, 184 pin, motherboard MS-7103. Your post implied that I could take it with me later - in that case shouldn't I invest in one stick? Each stick is $67. I have two slots total currently each has a 512mb stick.

You mentioned your friend did fine with 1 gig.

But now with the x1950 xt agp I'll be running shader 3 and some of this other high end stuff, and I imagine texture memory at only 256 will be taxed, and could perhaps slow me down.

Wouldn't the x1950xt agp (with only 256mb memory vs. your memory of 512mb) benefit from a little texture storage help from main system memory, which it would get if I open up the AGP aperture to 256mb? (Not as good as the memory being on the board itself - but somehow for agp that doesn't work.)

So Sam admittedly is not really an expert in this area, and doesn't need to be anymore since as you said some time back, PCI express does the memory allocation on the fly. Should I get the extra stick, and will it help? Should I get two sticks and max out at 2 gigs?

Thanks all you guys,

Rich

Hey guys, I am trying to get a little more cpu savvy by reading through some wiki articles. I just came across this in an article about the P4:

Quote:
Overclocking early stepping Northwood cores yielded a startling phenomenon. When VCore was increased past 1.7 V, the processor would slowly become more unstable over time, before dying and becoming totally unusable. This is believed to have been caused by the physical phenomenon known as Electromigration, where the internal pathways of the CPU become degraded over time due to excessive electron energy. This was also known as Sudden Northwood Death Syndrome.


Sam, is this what you were telling Raymond about?

Hey Raymond, it looks like you have the same P4 I do, 3.2.

The quote implies that you can go to 1.7 volts, and that the problem does not begin until you go past that voltage. I believe, Sam, you mentioned 1.6 as the upper limit. Were you being extra cautious, or did you have some other data? You talked about him burning out his cpu in the course of a few months no matter how cool it was running.

Finally, the thermal problems were so severe, Intel decided to abandon the Prescott architecture altogether, and attempts to roll out a 4 GHz part were abandoned, as a waste of internal resources. Also of concern was the fact that a review showed that in games, it took a 5.2 GHz Prescott core to soundly beat the performance of an Athlon FX-55 that clocked at 2.6 GHz.[4] Considering Intel boasted at launch the Pentium 4 architecture was intended to support up to 10 GHz operation, this can be seen as one of the most significant, certainly most public, engineering shortfalls in Intel?s history. This also meant that while Northwood ultimately achieved clockspeeds 70% higher than Willamette did, Prescott only managed a 12% rise over Northwood.


Another quote from wikipedia. Sam, is my P4 3.2 a Prescott, that sounds familiar to me. It is hot as hell. It does support hyperthreading.

Hey Raymond, if you can push yours to 4 Ghz, you will fulfill what the factory tried to do on a production basis, and then gave up on. (Although they talk about a 5.2Ghz Prescott - it must have been some type of overclocked heavily cooled monster.) Also, Sam, I don't find the Sudden Northwood Death Syndrome showing up in the discussion of the Prescott. So the worry over Raymond's cpu slowly burning itself out over the next few months if he amps his vcore too high, is that not applicable to the Prescott?

Waymon! Look at this:
Quote:
Overclocking record
In 2007, a frequency of 8.32 GHz was reached by an Italian overclocking team known as SFERA OC Team, using a Pentium 4 641 with a FSB of 520 MHz and a multiplier of 16. This is considered the highest clock frequency ever realized on a consumer CPU.


Sh*t, if they can hit over 8, then I think you can hit 4, Raymond, and I'll be right behind you (after I get the Gecube installed and working.) What do you think, Sam?

Hey dudes!

Sam what does this quote mean? Is this what you were talking about, games beginning to use multi-threading?

Quote:
NVIDIA's video drivers are now multithreaded, so we should see some amount of multithreading action happening in any application that uses the GPU for 3D graphics, even if the game is only single-threaded.
(Red added by me.)

...


These testers used some program of theirs to optimize multi-threading, which they were able to turn on and off. The XP task manager is thus showing two cpus, each multi-threaded (4 windows) with the optimization turned off, top set of 4 windows, and turned on, bottom set. Look at how much more evenly spread out is the cpu utilization on the bottom set of windows.

Then, the exciting part, the "proof of the pudding", the framerates, are on the right. On each set of bars, the upper longer and better bar comes from turning on the multi-threading feature, versus turning it off. As you said Sam, even if the game is single-threaded, at least in this case, Nvidia is multi-threading the graphics processing (and I am sure ati does the same thing, or soon will.)

By the way, the quote and graphic came from here - a bench of core 2 duo vs amd.
http://techreport.com/articles.x/10351/5

I am seeing what you are talking about in terms of architecture, Sam - the "wide" path, superior power per watt ratios, and modest clock cycles of core 2 duo architecture, (similar to amd) versus the narrow long path of Prescott in the earlier attempt by Intel to push to 10Ghz and be the clock cycle king, (until the chips started burning up.) Yeah, you told me to stop thinking of Ghz - I get it. However, since we already own these Prescotts, I still want to see Raymond push to 4Ghz, and me right behind him!

(Wow, Diamond viper has a 2900 card with 1 gig of DDR4 memory! vents out the back) http://www.diamondmm.com/2900XT1GPE.php

Well yes, but of course that implies a 64-bit operating system. To my knowledge you can't run 64-bit software on a 32-bit operating system without emulation, and the best 64-bit thing we've managed to emulate in windows so far is the Nintendo 64, a triumph, but nonetheless it's not exactly great considering you need at least a 2Ghz P4 to guarantee good performance emulating something that hada processor less than 100mhz.

AMD are still competitive, but now at the lower end of the market, they've had to slash their prices to compete with the core 2 duo since the Core is a superior product. You can find some absolute bargains, but the best performance is intel side, and given the cost of the e4300 now, you may as well go with that rather than an AMD, especially if you overclock. Keeping everything stock and using standard quality parts, 10% would be a good overclock for an Athlon64 X2. With a core 2 duo you should be ashamed if you can't manage 30%, 50% is a good target to aim for.

Waymon: Ah, I didn't realise the stock voltage was that high, I'm used to 1.325V! No problems then, 1.65 would be better than 1.7V really, but if you can't choose it I suppose 1.7 would be OK. I run my Chipset 0.3V higher than normal, it seems ok, but boy does it get hot!

Quote:
Sam, is this what you were telling Raymond about?
That's exactly what i was telling Waymon about, but it stands for any processor, not just a Northwood. His is probably a Prescott anyway.


Your 3.2Ghz is also probably a prescott, they are the newer generation of CPUs (despite the fact that they're not as good as the Northwoods they replaced, just like how the P3 was better than the p4)

Quote:
Sh*t, if they can hit over 8, then I think you can hit 4, Raymond, and I'll be right behind you

Do you guys have any idea the lengths people go to in order to get those overclocks?
It involves using Liquid nitrogen (pretty cold stuff!) to cool the CPU and a Vapour compressor to cool the chipset, running both at sub zero temperatures. I can assure you now that 4Ghz, while very impressive for a Prescott, is not that easy to achieve cost-effectively and permanently.


Multi-threaded drivers presumably mean that 3D data can be sent to the graphics card using two cores, which would ease off the frame calculating of the CPU a little. Games would have to be multi-threaded as well to take full advantage of that fact, but it was a start.

Diamond may have a 1GB HD2900XT but the sad reality is that the much older 768MB 8800GTX is still faster, and by now probably cheaper. It too vents out the back, and has done since it was first released nearly a year ago.

wow sam, what a coincidence! I was just getting bored last night and decided to put a list togeather to upgrade my computer to PCI-e this summer. It included:

Western Digital 10,000rpm 150GB Raptor X
OCZ GameXstream 700watt PSU
OCZ Ati Crossfire 2GB (2x 1GB) DDR2 800
ASUS P5B LGA 775 Intel P965 Express ATX Intel Motherboard
Intel Core 2 Quad Q6600 Kentsfield 2.4GHz
Microsoft Windows Vista 32-Bit Ultimate
Diamond
DIAMOND 2900XT1GPE Radeon HD 2900XT 1GB 512-bit GDDR4

Total Cost is around $1520USD

Is this ok? What do you think?

Oh yea, regarding the processor question, I have a Socket 478 Prescott 3.2GHz HT processor, running at 3.759Ghz according to CPUZ right now. So you think I can get to 4Ghz with 1.6v? Or will I need to up it more? The Bios goes (from smallest to largest) 1.6, 1.7, 1.8,1.9 blah blah blah.


EDIT: Btw, I found this cool video: http://video.google.com/videoplay?docid=...earch&plindex=1

It's pleasing to see that using GDDR4, the HD2900XT is finally a product to outperform the 8800GTX. I had no idea until I just looked how much better the Diamond Viper peforms. it being able to overclock to gain an extra 15% performance boost only sweetens the deal. That will be a kickass PC, Waymon, if a little loud.

I highly doubt you can get to 4Ghz with 1.6V. If you can't get there with 1.7V, don't try to get any further or you'll risk damaging the CPU. 4Ghz was a pretty amazing goal a while back, so don't think you'll have a doddle of a time of it.

Yea, I think I will only try to get to 4Ghz when I get all my new stuff, that way I can rsik blowing the $30 processor and replace it with a $250 one...

Any recommendations on a mobo though? I need something that will have 1 PCI-e slot since I wont be doing sli or crossfire, and I need 3PCI slots and something that has ddr2 800 as its main memory, any ideas? All suggestions are welcome since I'm still a noob at looking for mobos.

Oh yea, is it ok if I keep my processor at 3.75Ghz with 1.6volts? Or will the cpu blow later on?

1.6V isn't that much above stock, you should be alright. With regard to the motherboard, the Gigabyte GA-965P-DS3 revision 3.3 is a good one to go for.

That was an awesome video Raymond! Just what Sam was talking about.

Sam, you said that you read some stuff showing the Diamond outperforming the 8800 - the benches I read showed slightly underperforming? Can you link me to what you were reading. Thanks!

Well I read that the 8800 does outperform the 2900 in only some tests. In other tests the 2900 outperforms it... So I guess its half and half. I just dont ant to spend $650 on a graphics card... I would like one with GDDR4 and 1GB of vram, that way I can be ready for the future.

Well, the 2900 has 1gb of ram... Also has 320 stream processors, a higher core clock and memory clock... It runs with less heat also. Not really sure if my tidewater will fit it though... Or if it will even keep up with the heat.

Dont really want to spend $650 anyway, I want to stay under $1500 with my upgrade.

EDIT: sammoris, you really think my x1950xt will be able to play crysis? It comes out in 9 days here in the US, hope I can play it....

Well the thing that scares me most is that I just downloaded the World In Conflict demo-fantastic game by the way, and got fairly good fps in the beginning, but then they were pretty bad, usually about 10-15... I just hope I can play Crysis with medium, some high at 1024/768 with at least 20fps...

Wow I would think so at 1024 x 768. Maybe start out with everything on low settings, making sure you're at least getting 20 to 30 fps, then you can turn a few things on. I recently found out that I take a big fps hit with AF, but AA is not too bad, and vsynch doesn't hurt at all if I throw triple buffer in there which is supposed to fix the vsynch hit. However, with only 256mb on the Gecube, you might have to be careful about high settings on textures, fog?, etc. etc.

(That's why I like your thinking on the 2900 - 1 gig of memory, and all those shader pipelines doing 5 things at once versus the 8800 doing one thing at once - maybe not being fully implemented in programming now but I believe you're right about providing room for future growth.)

PWM FRIENDLY MOBOS DON'T EXIST

Just like you, Raymond, I'm thinking of my next machine. I acquired a huge education this weekend on cpus - core 2 duo, versus P4 architecture, etc. etc.

But I have given up on trying to find a pwm friendly core 2 duo 775 motherboard - I'm just going to buy the damn little Mcubed and let it sit at the bottom of the case. I found an Abit board with support for 6 fans, but the user manual showed that they were all 3-pin headers, except for the 4-pin pwm cpu fan. Sure abit allows you to control the speed of the other fans through voltage, not pwm, but it's basically a bios setting that goes from 40% to 100% (it is temperature dependent however, I will give them that.) But what about pwm?

The mobo manufacturers don't think it will sell any more boards for them, except Rich will buy one, so that is that. I found one other board, a Gigabyte, with 3 fan support, 2 of them with pwm. The speedfan site lists hundreds of boards that supposedly are pwm friendly. (They all have the added date of Nov 30, 1999, which is Alfredo's default date for everything, lol - some of the boards just came out.)

Looking at socket 775, there are still a ton of boards, and I could spend a solid week trying to find one that will run 4 pwm fans. I don't think there is any such thing. It's just so much easier to spend the $100 or $150 and buy the BigNG T-balancer from Mcubed and have it shipped here from Austria.

What do they get for Crysis? $50? Are you picking up a DVD or downloading from their web site.

By the way, I was just thinking about all the boards I have looked at this weekend, Raymond. Some of them were really set up for overclocking, with awesome copper coolers all around the chipsets - one of them is called the roller coaster design - loops of copper - I kid you not! The abit was highly reviewed - got some editor's choice awards. I know you want to overclock, and Sam says you should aim at 50% with the core 2 duo, but the $75 board he mentioned didn't seem like it had a lot of cooling on it when I went to look at it on Newegg to see if there was any pwm fan support.

The other boards were running $150 to $225, and the abit was priced a little lower at $185. I don't know if that will break your budget, but if you can make it up with the overclocking and effectively score a more expensive cpu that way, (course you're already factoring in quad 4 2.4 - pretty heavy merchandise - 50% that's 3.6 Ghz quad 4 - no cpu bound for you for a few years, huh) maybe it sort of pays for itself.

Plus the reviewers were specifically talking about the ease of the overclocking without having to amp up the volts that much, for some reason (I didn't pay 100% attention, looking for f'ing pwm support.) I got the idea that for some reason you don't have to juice the chipsets etc that much to ramp up the clock, don't remember why, Sam probably knows.

What's your take on all that Sam, higher end mobos with a lot more copper cooling, and easier o'cing. - Rich

If you're going to overclock, you'll need a well-cooled motherboard, without question. As for the frame rates for the later games, they'll all run on the X1950XT, but you'll have to turn a few things down. Even I will. Even an 8800GTX owner will.

Makes sense, Sam

What about that abit - do you like it? The pro model - sorry I don't have the exact model number handy. They don't make many boards. Their flagship board, socket 775, $184. Highly reviewed.

I see you changed your signature.
