Default Re: eVGA 6800U SLI on dual Opteron 250

All my ram is 400ecc buf 3200

This board has 8 slots, not 4.

Unless you mean 4 per CPU.

The 250 support 600, 800, 1000

the 252 support up tp 1.2 but they market them as 1. The HT bus is more dependent on what the board can do,

I usually will not run lesss than 1ghz

Venturi,
I went through all the posts and did not spot anywhere that stated what your system cost to build.

Care to share that info?

Thanks

The moment I share the cost - certain things will happen:

1. The price will be lower than expected and this will invite a littony of how's, and B.S. allegations and a slew of personal attacks from my bank account to the relationships with the actual makers of the hardware and software.

2. It will invite a series of "where did you get this or that for that much?"

4. Opens up issues on other posts that will inevitably quote and paraphrase the excerpts in the wrong methodology. No I don't want this thread to be a flame fest.

I want to keep this post technically informative without detracting from the sharing of knowledge.

I apologize for not answering this one question.

With sincere respect

VENTURI

Well said! In fact, the primary discussion here is the experience(s) in use and putting together components, along with discussion of performance-related aspects of such a high-end system.

Personal costs for reasons, as outlined, is secondary and not a subject of this thread.

Venturi can you please post the brand name of the sticks you are using and the actual part number of the modules or the chips used on the modules please?

Venturi,

I certainly understand your position on the price of the system. I see that you use it in your work, and understand that it's cost is immaterial in getting the job done in the best manner.

The question was asked to just save some time in estimating the cost on my own, and that was just for curiosity sake, as I am not in need of one anytime soon for my work.

I think it's great that you had the knowledge and wherewithall to build it, as your benches certainly answer a lot of "what-if" questions we all have.

I ran 3DMark 05 tonight on a 3.4 GHz system with an ATI 800XT, ( a Dell XPS Gen 3 machine picked up for my girlfriend from their refurbished shop), and am still amazed that the last part of the bench only sees 2 fps, and from what you stated, even your SLI system has stuttering in the same area.

When it comes to graphics performance, it looks like the next generation of cards, possibly using XDR memory, is really needed to see the 4-fold, or greater, increases needed to not stutter so much.

SLI performance increases are a testament to the benefit of multi-GPU architecture, so that when software becomes available, and stable, for the multi-CPU setup, as you have, along with fully functionable 64-bit software, maybe we will have reached the beginning of graphics utopia.

My best guess is a 1 - 2 year wait.

Thanks for all the time you have spent on your project, and sharing the results.

I still remember my first REAL video card for games. It was an OBSIDIAN x24, it was basically two voodoo2s on one slot. Back then 3dfx was big on GLIDE and I remeber how well the first Unreal game ran on it.

Well, I've been hooked ever since.

I suspect 64 bit will take longer than 2 years to be mainstream. Not because of technology but because of marketing. The corporate goal is to sell products that have a 20/80 rule that caters to basically the Wal-Mart shopper.

So, these high end systems really only cater to a few percent of the buying consumer force.

I apologise for not answering the q's on price. However, I did notice that you can find every component on Pricewatch so you could peacemeal a retail price from the site.

What does not show up, is the sweat equity. Despite whaht I thought was a good knowledge base, putting that system together took (from parts to running rig) about 12 hours. The darn cables and cooling were quite a work out to do it neat. The OS, drivers and finessing was another day.

yes, I was somewhat perplexed on the slow CPU tests in 3dmark-05. I had not expected such a low frame rate in the cpu tests. What machine delivers that section smoothly?


Ciao

Is 3Mark 2005 SMP capable? If not you probably won't see any benefits, more negatives than benefits IIRC.

Yeah man I loved my x24 card. That thing was the bomb for Quake 2! I sold that bad boy once the Riva TNT came out though. I loved that card!

NOPE, 3dMark is blind to the second processor. As a matter of fact it won't even see all the ram.

On the DETAILS tab, it reports 6.5Gb of ram (less than half)
It also does not report the speed of the chips, it just says "Engineering Processor 00"

The SLI does seem to work well with it although. But the CPU test seems to still stuuter and/or get low frames.

Hope that helps.

To be expected. That test is doing all the pixel/vertex shaders in software. Even at low resolution the highest end CPUS cant run it at any decent speed. That and the fact its not optimised for dual CPUS. To be fair to 3dmark05 there are practically no games that use the second CPU either. So it's pretty representive in that case.
